maya drive 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
8 hours
Step-by-step explanation:110 miles ................. 5 hours
176 miles ..................x hours
x = 176×5/110 = 880/110 = 8 hours
Answer:
maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
We use the rule of three
110 miles -------------> 5 hours
176 miles ------------> ???
So (176 miles × 5 hours) /110 miles
We simplify by 《miles》 because it is in the numerator and the denominator
SO (176×5 hours )/110
= 880 hours / 110
= 8 hours
So she drives 176 miles in 8 hours.

14f= -6
Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by the plumbers are listed. Which list shows these lengths in order from greatest to least?
Answer:
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]
Step-by-step explanation:
To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.
[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]
LCM of the denominators,
2 | 25 11 100 24
2 | 25 11 50 12
5 | 25 11 25 6
5 | 5 11 5 6
1 11 1 6
LCM = 2×2×5×5×6×11 = 6600
[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]
[tex]=\frac{792}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]
[tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]
[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]
[tex]=\frac{594}{6600}[/tex]
[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]
[tex]=\frac{275\pi }{6600}[/tex]
[tex]=\frac{864}{6600}[/tex]
Now we can arrange these fractions in the order of greatest to least.
[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]

===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates

Using that idea for the given vectors leads to
v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
v - w = < 10, 5 >

what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

the number of diagonals that can be drawn in a opolygon of n sides is 1/2n(n-1)-n. If 230 diagonsaals can be drawn how many sides does the polygon have'
Answer:
n = 20
Step-by-step explanation:
The number of diagonal that can be drawn in a polygon of n sides is given by :
[tex]D=\dfrac{n(n-3)}{2}[/tex]
If the number of diagonals are 230, then put D = 230 in above formula. So,
[tex]230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0[/tex]
It is a quadratic equation, the value of n is equal to 20.
It means that for 230 diagonal, there are 20 sides of the polygon.
The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same
What is the value of p in the linear equation 24p +12 - 18p = 10 + 2p - 6 ? −4 −2 2 4
Answer:
SO we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
p = -2
The value of p is -2.
The correct option is (B)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
24p +12 - 18p = 10 + 2p - 6
Now, solving for p
6p + 12= 2p + 4
6p - 2p = 4 -12
4p = -8
p= -8/4
p= -2
Hence, the value of p is -2.

We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5hd, equals, 5, h. How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour?
Answer:
a) 0.2 h
b) 5 cm
Step-by-step explanation:
The given equation is:
[tex] d = 5h [/tex] (1)
Where:
d: is the depth in centimeters
h: is the time in hours
a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:
[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]
Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
b) The depth in centimeters of snow accumulate per hour is:
[tex] d = 5h = 5*1 = 5 cm [/tex]
Therefore, 5 cm of snow accumulates per hour.

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3
Answer:
126 in³
Step-by-step explanation:
Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:
Volume of cylinder = πr²h
Where,
r = radius = ½ of d = ½*4 = 2 in
h = height = 10 in
Take π as 3.14
Plug in the values into the formula
Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign of the larger number. In complete sentences explain what Hannah got wrong. What should the correct answer be?
Answer:
The sum is 1
Step-by-step explanation:
When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.
Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.
