Answer above is correct
Gennadij [26K]3 years ago

Answer: D

Step-by-step explanation: slope = "rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing

slope is the change in height, the vertical change, divided by the change in horizontal distance

2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot

slope = 1/18 = (1/2)/9  

the door is 2 feet higher than the ground level,  1.5 + .5 = 2 feet change vertically

Find the missing side lengths
lora16 [44]

Answer:

the side lengths will be 4√2- 4√2 - 8

Step-by-step explanation:

When you have missing side lengths of a right triangle, you can use special triangles to find the side lengths.  Where the angles are 45-45-90, each triangle has side lengths with the relationship 1 - 1 -√2.

This means for problem 9, the side length 8 is the equivalent of the special triangle √2 * √32 = √64 = 8. So each side is multiplied by √32.

So the side lengths will be 4√2- 4√2 - 8.

These are found using:

1*√32 = √32 = 4√2

1*√32 = √32=4√2

√2*√32 = √64 = 8

I will give brainiest to whoever answers correctly !!
tigry1 [53]

Answer:

The graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.

Step-by-step explanation:

This can be determined using the formula for calculating the future value (FV) formula as follows:

FV = PV * (1 + r)^n ................................. (1)

Where;

FV = Future value or the amount the graduate will have at end of 36 months = ?

PV = Present value or the total amount invested = Cash gifts from friends and relatives + Amount of 3 scholarships he received = $900 + $250 + $300 + $1,400 = $2,850

r = daily interest rate = 1% / 360 = 0.01 / 360 = 0.0000277777777777778

n = number of days = 36 months * 360 days = 12,960

Substituting the values into equation (1), we have:

FV = $2,850 * (1 + 0.0000277777777777778)^12,960

FV = $2,850 * 1.43332224806396

FV = $4,084.96840698229

Approximating to the nearest cent as required, we have:

FV = $4,084.97

Therefore, the graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.

ernesto baked 3 cakes in 2 1/2 hours. Assume that the number of cakes baked varies directly with the number of hours. Write and
Masja [62]

3 cakes in 2.5 hours

Divide 7.5 (hours you are solving for) by 2.5 (known hours for 3 cakes)

7.5/2.5=3

Multiply that answer, 3 * 3= approximately 9 cakes in 7.5 hours
