Answer:
[tex]3\frac{1}{4}[/tex]
Step-by-step explanation:
Given the two -3 1/4 and -6 1/2 numbers on the line, the distance between he numbers can be gotten by simply taking the differences between both values as shown;
[tex]= -3\frac{1}{4} -(-6\frac{1}{2} )\\ \\= -\frac{13}{4} + \frac{13}{2}\\ \\= \frac{-13+26}{4}\\ \\= \frac{13}{4} \\\\= 3\frac{1}{4}[/tex]
Hence the distance between two numbers on the number line is [tex]3\frac{1}{4}[/tex]

The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about ______ times that of the Sun-Earth system.
References:
The distance to size ratio of the Sun- Nearest Star system is 100,000,000
The distance to size ratio of the Sun-Earth system is 10,000
Hint you have to divide them, however, the answer is not 10,000
Please help! I will mark the brainliest!
Answer: 1:10,000
Step-by-step explanation:
given data:
distance of the nearest star system = 100,000,000
distance to size ration of the sun earth system = 10,000
therefore;
100,000,000 / 10,000
= 10,000
The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.

Solve for . 5w-26=-4(w-7) Simplify your answer as much as possible. PLZ HELP
Answer:
w = 6
Step-by-step explanation:
5w-26 = - 4 (w - 7) multiply -4 through
5w - 26 = - 4w + 28 add 4w to each side to cancel it out on the right
5w + 4w - 26 = 28
9w - 26 = 28 Now add 26 to each side
9w - 26 + 26 = 28 + 26
9w = 54 Now divide each side by 9
(9w)/9 = 54/9
w = 6
Some fireworks are fired vertically into the air from the ground at an initial velocity of 24.5 meters per second. Find the highest point reached by the firework – just as it explodes. Include your equation in your response. Don't forget to include units!
Answer:
The highest point reached by the firework is approximately 30.6 meters
Step-by-step explanation:
The upward velocity of the fireworks is given as 24.5 m/s
The equation of projectile motion for an object fired vertically upwards can be written as follows;
v² = u² - 2·g·s
Where;
v = The final velocity of the motion = 0 m/s at maximum height
u = The final velocity of the motion = 24.5 m/s
g = Acceleration due to gravity = 9.81 m/s²
s = The height reached = (The highest point reached by the firework)
By substituting the values, we have;
(0 m/s)² = (24.5 m/s)² - 2 × 9.81 m/s² × s
Which gives;
2 × 9.81 m/s² × s = (24.5 m/s)² = 600.25 m²/s²
19.62 m/s² × s = 600.25 m²/s²
s = 600.25 m²/s²/(19.62 m/s²) = 30.594 m ≈ 30.6 meters
The highest point reached by the firework is approximately 30.6 meters

Answer:
y = 5 units
Step-by-step explanation:
It is given from the image that both the polygons are similar.
Corresponding sides of the similar polygons will be proportional.
By this property ratio of the sides of the given polygons will be,
[tex]\frac{4}{x}=\frac{z}{9}=\frac{2}{6}=\frac{3}{w}=\frac{y}{15}[/tex]
We have to find the value of y.
Therefore, we will take the ratio,
[tex]\frac{2}{6}=\frac{y}{15}[/tex]
y = [tex]\frac{2\times 15}{6}[/tex]
y = 5
Measure of side y = 5 units will be the answer.
Glenn bought 3 pounds of tomatoes. He used bles of them to make sauce. Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce. Move numbers and symbols to the blanks to complete the equation. If there is no whole number in the answer, put a 0 in the first box after the equals sign.
Answer:
He used [tex]1\frac{7}{8}\ lb[/tex]
Step-by-step explanation:
Given
[tex]Total = 3\ lb[/tex]
[tex]Fraction = \frac{5}{8}[/tex] to make sauce
Required
Determine the number of pounds used
To solve this, we simply multiply the fraction of tomato used by the total;
[tex]Used = Fraction * Total[/tex]
[tex]Used = \frac{5}{8} * 3\ lb[/tex]
[tex]Used = \frac{5 * 3}{8}\ lb[/tex]
[tex]Used = \frac{15}{8}\ lb[/tex]
Convert to mixed number
[tex]Used = 1\frac{7}{8}\ lb[/tex]
Hence,
He used [tex]1\frac{7}{8}\ lb[/tex] out of the 3lb he bought

Answer:
x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
f(x) = [tex]\frac{x-4}{2x-3}[/tex]
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
Thus x = [tex]\frac{3}{2}[/tex] is the vertical asymptote

Answer: 12/g
(these are the rest of the answers for the rest of the 7 slides of "Writing expression" assignment on e2020
4th: $25 dollars is the constant team so the cost for h hours is 15h and the correct expression is 15h+25 and 15(h+25) would be interpreted as adding 25 hours to the number of hours rented, and then multiplying by 15.
5th: m + 2m - s
6th: No it's not true. Each table began with x/8 balloons. If two pop then you will not be able to distribute it equally among 8 tables. There are x/8 - 2 balloons left. Not all tables will be equal.
7th: n - (1/4)n - 15
8th: 12n/r
9th: (x+3)/5
10th: (3r)/2 is what the second DJ had. 3 times as many songs as 3r and half as many is translated as division to 2 so half as many is translated as multiplication by 1/2. So therefore, the second DJ had (3r)/2 songs.

Derek is purchasing lunch meat for the class picnic. There are 300 people attending the picnic. Derek expects that for every 10 people 11 sandwiches will be eaten and that 20 pounds of meat will make 90 sandwiches. How much lunch meat should Derek buy? 73 1/3 pounds 330 sandwiches 67 2/3 pounds 110 pounds
Answer:
Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches
Step-by-step explanation:
People at the picnic = 300
For every 10 people 11 sandwiches will be eaten
Total sandwiches eaten by 300 people = 300/10 × 11
= 30*11
= 330 sandwiches
330 sandwiches will be eaten at the picnic
20 pounds of meat will make 90 sandwiches.
90/20 = 330/x
Cross product
90x = 330*20
90x = 6,600
Divide both sides by 90
x= 73 1/3
Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches
73 1/3 pounds 330 sandwiches

What is the value of x in the equation 1/2x - 2/3y=30 when y =15
Answer:
x=20
Step-by-step explanation:
Substitute 15 for y
it will be 2/3 multiplied by 15 then you get 10
you add 10 to 30 getting 40
then you divide 40 by 1/2 getting 20
:)))
Answer:
x = 80
Step-by-step explanation:
First, plug the 15 into the y.
[tex]1/2x - 2/3(15) = 30[/tex]
Use PEMDAS to solve the parentheses, 2/3 of 15 is 10.
[tex]1/2x - 10 = 30[/tex]
Add 10 to both sides of the equation.
[tex]1/2x = 40[/tex]
Divide each side by 1/2 (or multiply by it's reciprocal, which is 2)
That will get you your answer of x = 80
-3x + 5 = 2x + 10 what is the answer
Answer:
x = -1
Step-by-step explanation:
Step 1: Write out equation
-3x + 5 = 2x + 10
Step 2: Add 3x on both sides
5 = 5x + 10
Step 3: Subtract 10 on both sides
-5 = 5x
Step 4: Divide both sides by 5
-1 = x
Step 6: Rewrite
x = -1
Answer:
x = -1
Step-by-step explanation:
you want to move all the numbers with an x to one side and the ones without to the other so you get.
-5x=5
then you divide by 5 on both sides and get x = -1

Six times a number is at least four less than eight times the number. If x represents the number, which will help find the number?
Answer:
The first thing you need to do here is create an equation.
I've created it for you: 6x = 8x - 4
If you want to solve it, you have to move the like terms to one side so...
4 = 2x
and x = 2

I need help finishing a question. I used the explanation function on the program, but it didn't specify what to do to get the final answer. I have attached a picture.
"Find the real solutions. Use the quadratic formula and a calculator."
At the last step, it said to use a calculator to see if the solutions satisfy the equation, but does that mean I need to plug in the whole thing for each x in the original equation? That would take a long time. I tried punching the "(1 plus or minus sqrt (1 + 160pi^2)) / 2" into my calculator, but the answers I got were wrong.
I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337
Add this to 1 and we have 40.75093337
Then divide over 2pi to get a final approximate result of 6.48571248
So x = 6.48571248 is one approximate solution
In short, I computed [tex]\frac{1+\sqrt{1+160\pi^2}}{2\pi}[/tex] only focusing on the plus for now.
----------------------
If you were to compute [tex]\frac{1-\sqrt{1+160\pi^2}}{2\pi}[/tex] you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.
Answer:
x = 6.49
Step-by-step explanation:
1st is to calculate [tex]\sqrt{1 + 160 pi^2}[/tex] = 39.75 then add 1 = 40.75
2nd divide it by 2pi = 40.75/(2pi) = 6.49
therefore your x = 6.49
the equation would look like
1 ± [tex]\sqrt{1 + 160 pi^2}[/tex] 1 ± 39.75
= -------------------------- = ---------------- = 6.49
2*pi 6.28
What is 4.5(5.6*2)+1.2?
Hi there! Hopefully this helps!
---------------------------------------------------------------------------
Answer: [tex]\boxed{51.6}[/tex]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[tex]4.5(5.6 \times 2) + 1.2[/tex]
Multiply 4.5 and 5.6 to get 25.2.
[tex]25.2 \times 2 + 1.2 = 51.6[/tex]
Multiply 25.2 and 2 to get 50.4
[tex]50.4 + 1.2 = 51.6[/tex]
Add 50.4 and 1.2 to get, you guessed it, 51.6![tex]\boxed{51.6}[/tex]
To solve this, we will first use order of operations to multiply the terms inside the parentheses, multiply the product by the term outside of the parentheses, and then add from left to right.
5.6 * 2 = 11.2
11.2 * 4.5 = 50.4
50.4 + 1.2 = 51.6
Therefore, 51.6 is the solution.

The coordinates of points A and B are A(4, -2) and B(12, 10). What are the coordinates of the point that is 1/4
of the way from A to B?
Answer:
[tex](x,y) = (\frac{28}{5},\frac{2}{5})[/tex]
Step-by-step explanation:
Given
A = (4,-2)
B = (12,-10)
Ration = 1/4
Required
Determine the coordinate of point at 1 million buys
The formula to use is as follows:
[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
Where m and n are the ratios
i.e.
[tex]\frac{m}{n} = \frac{1}{4}[/tex]
Convert to ratios
[tex]m:n = 1:4[/tex]
Considering A(4,-2) and B(12,10); we have
[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
[tex](x,y) = (\frac{1 * 12 + 4 * 4}{4+1},\frac{1*10 + 4*-2}{4+1})[/tex]
[tex](x,y) = (\frac{12 + 16}{5},\frac{10 -8}{5})[/tex]
[tex](x,y) = (\frac{28}{5},\frac{2}{5})[/tex]
Hence, the coordinate of the point is [tex](x,y) = (\frac{28}{5},\frac{2}{5})[/tex]

Choose one value that is in the domain of both ( ) = 2and 2 = and that is greater than 0. Substitute that value into ( ) = 2and 2 = and then simplify. Explain how your answers help to show that the graph on the left represents a function while the graph on the right represents a relation. Show your work and use function notation where possible
(ignore the little checks on the graph lol)
Heres a Simple Answer:
1. The one on the left follows the Vertical Line test, while the one on the right doesn't
2. A function is either y = mx+b, or a Nonlinear function. The one on the right is a Parabolic Function becuase it has the x^2 on it. The right one is y^2, which is not a function.
