Answer:

Perimeter is distance around the room.

Perimeter = 14 + 10 +14 +10 = 48 feet

Rolls needed = Perimeter / roll length = 48 /20 = 2.4.

Since you can't buy a partial roll you have to get a full roll

Rolls need = 2.4 rounded up to the next number is 3.

Use the equation to answer the questions. Round both answers to nearest whole number. Y = 47.25 − 2.25 X If Y equals 8 , what is

noname [10]

Answer:

If Y equals 8, X is equal to 17.

If Y drops to 4, X is equal to 19.

Step-by-step explanation:

We know that the equation is $Y = 47.25- 2.25X$ and we want to find X when Y = 8. To do this we solve the equation for X.

$47.25-2.25X=8\\47.25\cdot \:100-2.25X\cdot \:100=8\cdot \:100\\4725-225X=800\\4725-225X-4725=800-4725\\-225X=-3925\\\frac{-225X}{-225}=\frac{-3925}{-225}\\X=\frac{157}{9}=17.4444...$

17.4444 rounded to the nearest whole number is 17.

If Y drops to 4,

$4 = 47.25- 2.25X\\47.25-2.25X=4\\47.25\cdot \:100-2.25X\cdot \:100=4\cdot \:100\\4725-225X=400\\4725-225X-4725=400-4725\\-225X=-4325\\X=\frac{173}{9}=19.2222...$

19.2222 rounded to the nearest whole number is 19.

For the triangle above, find sin A. a. 36° c. 0.9323 b. 50° d. 0.385

Lerok [7]

The picture in the attached figure

we know that
in the right triangle ABC
sin A=opposite side angle A/hypotenuse

in this problem
opposite side angle A=BC-----> 10
hypotenuse=AB-----> 26
so
sin A=10/36------> sin A=0.3846------> sin A=0.385

the answer is
the option <span>d. 0.385</span>
