Answer:
20
Step-by-step explanation:
1/5(6+3+1)^2
PEMDAS says parentheses first
1/5(10)^2
Then exponents
1/5 *100
Then multiply
20
Answer:
[tex]\Huge \boxed{\mathrm{20}}[/tex]
Step-by-step explanation:
[tex]\Rightarrow \displaystyle \frac{1}{5} \cdot (6+3+1)^2[/tex]
Solve for the brackets or parenthesis first.
Adding the terms in the brackets or parenthesis.
[tex]\Rightarrow \displaystyle \frac{1}{5} \cdot (10)^2[/tex]
Solving for the exponent or power.
[tex]\Rightarrow \displaystyle \frac{1}{5} \cdot (100)[/tex]
Multiplying both terms.

After taxes, Alexandra's take home pay is 3 10 of her salary before taxes. Enter and solve an equation to find Alexandra's salary before taxes for the pay period that resulted in $162 of take-home pay. Let s represent your variable. The equation is . Alexandra's salary before taxes for the pay period was $
Answer:
The equation is 3/10 × s = 162
Alexandra's salary before taxes for the pay period was $540
Step-by-step explanation:
Let
Alexander's salary before taxes
=s
3/10 if Alexander's take home pay is $162 after taxes
3/10 of s = $162
The equation is
3/10 × s = 162
Divide both sides by 3/10
s = 162 ÷ 3/10
= 162 × 10/3
= 1620 / 3
= $540
Alexandra's salary before taxes for the pay period was $540
–2 times the quantity q minus 3
Answer:
This question was worded weirdly however I am assuming this is algebra and you need the equation. So here- -2(q-3) or -2q+6
Step-by-step explanation:
Distribute the -2, to all the terms in the parenthesis of -2(q-3) you get 2q+6
If you didnt know how to get -2(q-3), -2(multiplied) by q-3, you use parenthesis to make sure you know it is multiplication in front of the parenthesis.

Tell which set or sets the number below belongs to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers. 0
Answer:
Step-by-step explanation:
Natural numbers are otherwise called counting numbers. Numbers you can count, and excludes Zero.
Whole number is a little extension of natural numbers in that, they contain Zero. So, they're counting numbers including Zero and excluding negative numbers.
Integers are whole numbers in general. They also include negative numbers.
Rational number is a number that can be written as ratio. It can be written as a fraction in which both the denominator and the numerator are whole numbers.
Irrational numbers are very opposite to rational numbers, and can not be written as fractions.
Real numbers are the culmination of both rational and irrational numbers

Anyone down to help? 12pts for PRE-ALGEBRA question Use the information in the table for 2–4.
Answer:
See attached image
Step-by-step explanation:
If the number of blueberries is the x value, and number of calories is the y value, then we can create the ordered pairs (5,4) (10,8) (15,12) based on the data in the table.
Plotting these on the graph is simple - just go to the x value then the y value and plot where these lines meet.
The slope of a line is always the rise over run.
Every time our x increases by 5, our y increases by 4. The rise is 4, and run is 5, so the slope is [tex]\frac{4}{5}[/tex]

A falcon flew 70 miles in 3 hours. What was the speed of the falcon?
Answer:
23.3333333 miles per hour
23 1/3 miles per hour
10.43093333333333 meters / second
Step-by-step explanation:
Take the distance and divide by the time to find the speed
70 miles / 3 hours
1 mile = 1609.34 meters
1 hours = 3600 seconds
70 miles /3 hours * 1 mile /1609.34 meters * 1 hours / 3600 seconds
10.43093333333333 meters / second
Step-by-step explanation:
speed is normally measured in unit time meaning either per hour,second,minute etc
therefore for this question you will have to find what it travels per hour
if 70 is in three hours what about one hour
therefore
70/3=23.3'
so the speed will be 23.3miles per hour

find the equation of the line parallel to H passes through (-4,2)
Answer:
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{10}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate the slope m of H using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = [tex]\frac{-2+3}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 4, 2) into the partial equation
2 = - [tex]\frac{4}{3}[/tex] + c ⇒ c = 2 + [tex]\frac{4}{3}[/tex] = [tex]\frac{10}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{10}{3}[/tex] ← equation of parallel line

Celina and Zoe both sing in a band.
One evening the band plays for 80 minutes.
Celina sings for 65% of the 80 minutes.
8
Zoe sings for of 5/8 of the 80 minutes.
Celina sings for more minutes than Zoe sings.
Work out for how many more minutes.
Step-by-step explanation:
65% of 80= 80×0.65 = 52mins
5/8 of 80= 5/8×80 = 50 mins
more mins = 52-50= 2 more minYin practiced 604 minutes of piano. She plans to reach 700. How much minutes does she need to reach her goal?

6c-8-2c=-16+c what’s the value of c
Answer:
The correct answer is c = -8/3.
Step-by-step explanation:
The first step in solving this problem would be to simplify by combining like terms on the left side of the equation.
6c - 8 - 2c = -16 + c
4c - 8 = -16 + c
Then, we can subtract c from both sides of the equation to get rid of the positive c on the right side of the equation.
4c - c - 8 = -16 + c - c
3c - 8 = -16
Next, we can add 8 to both sides of the equation.
3c - 8 + 8 = -16 + 8
3c = - 8
Then, we can divide both sides of the equation by 3.
c = -8/3

The last two answers for the last question are c. h(g(x))= 1/ (x^2 +4) and d. h(g(x))=1/x^2 +4
Answer:
I'm pretty sure the answer to the third question is C
Step-by-step explanation:
We are solving for h(g(x)).
We already know that g(x) is equal to x^2+4.
So know, we can simplify our expression, h(g(x)), to h(x^2+4).
We also know that h(x)=1/x
we simply substitute x for x^2+4, giving us an answer of 1/(x^2+4)
Of the 100 children in the sixth grade
class, 76 can go on the end-of-the-year
field trip. What percentage of the
children can go on the trip?
Any number out of 100 can be quickly converted to percent form by just tacking on the percent sign. This is because "percent" is "per one hundred". Think of 100 cents in a dollar which may help you remember.
So 76/100 = 76%
i really need help please answer this
Answer:
Option 1
Step-by-step explanation:
Solve each piece individually first.
4 ^(1/2) = 2
The 4th root of 16 is 2 so 2/2 = 1
So we have:
2 * 1 - 10 ÷ 2
Order of operations.
2 * 1 = 2 10 ÷ 2 = 5
2 - 5 = -3
The answer is the first option.

Given that a rectangle with length $3x$ inches and width $x + 5$ inches has the property that its area and perimeter have equal values, what is $x$
Answer:
First, we need to know how to calculate the area and the permiter of a rectangle.
To calculate the area, we multiply base by height and to calculate the perimeter, we sum all sides.
Knowing this, we can say that the area is 3x * (x+5) and the perimiter is 3x + 3x + x + 5 + x + 5, as we know both are the same, we write it as an equation:
[tex]3x * (x+5) = 3x + 3x + x + 5 + x + 5[/tex]
Now we solve the equation:
[tex]3x^2 +15x = 6x + 2x + 10[/tex]
[tex]3x^2+15x =8x + 10[/tex]
[tex]3x^2+15x-8x-10=0[/tex]
[tex]3x^2+7x-10=0\\\\x_1=\frac{-10}{3}\\x_2 = 1[/tex]
As the negative result doesn't have sense, we only pick the second one: 1.
If x = 1, then area would be 3*6 = 18 square inches and perimeter 3+3+6+6 = 18 inches
Answer:
[tex]\huge\boxed{x = 1 \ \ \ \ OR \ \ \ \ x = -\frac{10}{3} }[/tex]
Step-by-step explanation:
Length = 3x
Width = x + 5
Area of Rectangle:
=> (Length)(Width)
=> (3x)(x+5)
=> [tex]3x^2 + 15x[/tex]
Perimeter of Rectangle:
=> 2 (Length) + 2 (Width)
=> 2(3x) + 2(x+5)
=> 6x + 2x + 10
=> 8x + 10
Given Condition is:
Perimeter = Area
[tex]3x^2 + 15x[/tex] = 8x + 10
[tex]3x^2 + 15 x -8x - 10 = 0\\3x^2 + 7x -10 = 0\\3x^2 + 10 x - 3x -10 = 0\\x(3x+10) - 1(3x+10) = 0\\(x-1) (3x+10) = 0[/tex]
Either,
x - 1 = 0 OR 3x + 10 = 0
x = 1 OR 3x = -10
x = 1 OR x = -10 / 3
