Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A =
=
=
, then
∠ A =
(
) ≈ 41° ( to the nearest degree )
The sum of the angles in the triangle = 180° , then
∠ B + 41° + 90° = 180°
∠ B + 131° = 180° ( subtract 131° from both sides )
∠ B = 49°
Using Pythagoras' identity in the right triangle
AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )
AB =
≈ 10.6 ( to the nearest tenth )
From fraction to decimal: divide the numerator by the denominator
From decimal to percent: move the decimal two places to the right. For example: 0.062=6.2%
From percent to decimal: move the decimal point two steps to the left. For example: 56%=0.56
From decimal to fraction: Rewrite the decimal number number as a fraction (example: <span>2.625=<span>2.6251</span></span>) an then Multiply by 1 to eliminate 3 decimal places, we multiply numerator and denominator by 10 cubed = 1000<span><span><span>2.625/1</span>×<span>1000/1000</span>=<span>2625/1000 and don forget to reduce if possible;)

The answer is D (42.39 cubic inches)
Answer:
135,000 times
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
<u>We need to know the size of your bakery store. </u>
As we can see, the entire shopping center is: 45000 square feet and your shop is 1/10 of that space
=> Your shop area is: 45000*1/10 = 4500 square feet
In the question, they want to know how many thirtieths of the space does it take up, so let say thirtieths in numerical is: 1/30
Hence, the number of thirtieths it takes:
=
= 135,000 times
Hope it will find you well.
Answer:
-51
Step-by-step explanation:
PEMDAS suggests you start with parenthesis
10+9•(-3)2-(7)
10-(27)2-(7)
