Answer:

22%

Step-by-step explanation:

Well if the ramp can hold 1000lbs and 6 people all weight 780 in total (they must be really fat lol, but anyway) we can make the following fraction.

780/1000

So now we simplify the fraction to 39/50.

And do 39 / 50 = .78

To make that a percent we move the decimal point 2 times to the right so 78% of the ramp‘s capacity is being used meaning there is stil 22% capacity left.

Answer:

4x-7

Step-by-step explanation:

Solve for x:

180 = 44 + 3x - 11 + 4x - 7

Combine like terms: 180 = 26 + 7x

Simplify: 154 = 7x

Simplify: 22 = x

Substitute: 3(22) - 11 = 55 and 4(22) - 7 = 81

Create inequality: 44 < 55 < 81

An airplane is flying from New York city to Los Angeles.The distance it travels in Miles, D, is related to the time in seconds,

deff fn [24]

We have been given an equation $d=0.15t$ that represents the distance an airplane travels in Miles (d) is related to the time in seconds (t).

A. Upon substituting t=1 in our equation we will get,

$d=0.15\times 1$

$d=0.15$

We can see that our plane is travelling at rate of 0.15 miles per second.

$\text{Speed of plane }=0.15\frac{\text{miles}}{\text{second}}$

Therefore, plane is flying at the rate of 0.15 miles per second.

B. To find distance traveled by airplane in 30 seconds we will substitute t=30 in our given equation.

$d=0.15\times 30$

$d=4.5$

Therefore, plane will travel 4.5 miles in 30 seconds.

C. To find time it will take to travel 12.75 miles we will substitute d=12.75 in our given equation.

$d=0.15\times t$

$12.75=0.15\times t$

$t=\frac{12.75}{0.15}=85$

Therefore, plane will take 85 seconds to travel 12.75 miles.

Can someone help with this please it confusing

Part (a)

Since point E is on segment AD, this means the slope of ED is the exact same as the slope of AD.

Use the slope formula to calculate the slope of AD.

m = (y2-y1)/(x2-x1)

m = (7-2)/(4-0)

m = 5/4

<h3>Answer: 5/4</h3>

====================================================

Part (b)

The same idea and steps apply as part (a)

<h3>Answer: 5/4</h3>

====================================================

Part (c)

The x coordinates are the same, so we subtract the y coordinates to find the distance between C and D, which is the length of segment DC.

7-2 = 5

<h3>Answer: 5 units</h3>

====================================================

Part (d)

This time, the y coordinates are the same. We'll subtract the x values

4-2 = 2

<h3>Answer: 2 units</h3>

====================================================

Part (e)

Same idea as part (d), just different numbers this time.

2-0 = 2

<h3>Answer: 2 units</h3>

I can't get the answer!!!! >:(

Answer:

The scale factor of the smaller rectangle to the larger rectangle is 3/2

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

To find out the scale factor of the smaller rectangle to the larger rectangle. set up a proportion

$\frac{9}{6}=\frac{3}{2}$ ----> ratio of corresponding heights

$\frac{12}{8}=\frac{3}{2}$ ----> ratio of corresponding bases

therefore

The scale factor of the smaller rectangle to the larger rectangle is 3/2
