options:
1.6 miles
3.375 miles
3.75 miles
5.25 miles
Answer:
3.375 miles
Step-by-step explanation:
A runner runs at a rate of 4.5 miles per hour. How far does the runner run in 0.75 hours?

Answer: 2, 8, 96cm^2, 35 miles
Explanation:What we know:
We need to solve all of the given problemsWe have the information we needWe can use ratios to our advantageHow to solve:
By using our knowledge of ratios and substitution, we can solve these problems.
Process:First problem
Set up ratio 7.5:15
Find GCF (7.5:15)/7.5
Simplify 1:2
Solution: 2
Second problem
Set up equation (x/10) = (6/7.5)
Rewrite (x/10) = (60/75)
Simplify (x/10) = (4/5)
Common denominator (x/10) = (8/10)
Isolate variable [(x/10) = (8/10)]*10
Simplify x = 8
Solution: 8
Third Question
where x represents the new width, y represents the new length, and A represents the new area.
Set up equation A = xy
Substitute A = (2*4)(2*6)
Simplify A = (8)(12)
Simplify A = 96
Solution: 96 cm^2
Fourth Question
Where x represents the unknown length in miles
Set up equation (21:3) = (x:5)
Rewrite in fraction form [(21/3)] /3 = (x/5)
Simplify (7/1) = (x/5)
GCF 5(7/1) = (x/5)
Isolate variable [(35/5) = (x/5)]*5
Solution: 35 miles = x
Answer: 2, 8, 96 cm^2, 35 milesCheck:Problem 1:
If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:
(1/2^2)(15*15) = (7.5*7.5)
(1/4)(15^2) = (7.5^2)
225/4 = 56.25
56.25 = 56.25
Therefore, a scale factor of 2 is correct.
Problem 2:
If x = 8, then 8/10 should equal 6/7.5. Let's solve this:
when x = 8:
8/10 = 6/7.5
0.8 = 0.8
Therefore, x = 8 is a correct solution.
Problem 3:
If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:
(1/2^2)(96) = (6*4)
(96/4) = 24
24 = 24
Therefore, the new area is 96 cm^2.
Problem 4:
If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:
(21/3) = (35/5)
7 = 7
Therefore, the houses are 35 miles apart.

Step-by-step explanation:
256 ft² wood will be needed for 4 props.
What is Surface Area?The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.
According to the figure,
The lengths are
= (5ft +8ft +7ft +2ft +3ft +5ft) x 2 x 4
= 32 x 2 x 4

The number of customers at Yummy Smoothies varies throughout the day. During the lunch rush on Saturday, there were 120 customers at Yummy Smoothies. The number of customers at Yummy Smoothies during dinner time was 10 customers fewer than the number during breakfast. The number of customers at Yummy Smoothies during lunch was 3 times more than during breakfast. How many people were at Yummy Smoothies during breakfast? How many people were at Yummy Smoothies during dinner? Let d represent the number of customers at Yummy Smoothies during dinner and b represent the number of customers at Yummy Smoothies during breakfast.
Answer:
190 people
Step-by-step explanation:
At lunch, there were 120 people.
There were 3 times more people at lunch than breakfast meaning you divide 120 by 3.
120 / 3 = 40
At dinner, there were 10 people less than at breakfast.
40 - 10 = 30
Add up your numbers.
120 + 40 + 30 = 190

Volume = length x width x height
This formula can be used to find the number of cubes as well as the volume.
Number of Cubes: 36
3 x 4 x 3 = 12 x 3 = 36
Volume of One Cube: 1/64 cm^3
1/4 x 1/4 x 1/4 = 1/64
Volume of the Solid: 9/16 cm^3
Length = 1/4 + 1/4 + 1/4 = 3/4
Width = 1/4 + 1/4 + 1/4 + 1/4 = 1
Height = 1/4 + 1/4 + 1/4 = 3/4
3/4 x 1 x 3/4 = 9/16

Step-by-step explanation:
The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area
a = 5m
b = 12m
c = 13m
L = 11m
First, we need to find the base area...
base area = (a*b)/2
(5*12)/2 = 30 m^2
Next, find the surface area
A = 11(5 + 12 +13) + 2*30 = 390 m^2

A corner store sells 60-watt bulbs in packs of 4.
Write an equation that shows how the number of bulbs in stock, y, depends on the number of packages, x.
Answer: y = -4x + 60
Step-by-step explanation:
we can use a simple linear equation to write this problem:
y = mx + b
The slope is given to be the number of bulbs in each pack, which is 4.
now we have: y = 4x +b
The value of b is the y intercept, or the starting value, 60. From this value, 4x can be subtracted to show our remaining bulbs in stock:
y = 60 - 4x
Writing this in the form y = mx+b gives us the equation:
y = -4x + 60
Answer:
y = 4x
Step-by-step explanation:
A corner store sells 60-watt bulbs in pack of 4.
x = number of packs
y = number of bulbs
y = 4x
Check your answer using the problem:
60 = 4x
/4 /4
12 = x
This means that there are 12 bulbs in each pack.
Hope this helps!
