Answer:
D. 96
Step-by-step explanation:
Using the Multiplication Principle, we multiply the number of choices for each item together:
![8 \cdot 4 \cdot 3 = 96](https://tex.z-dn.net/?f=8%20%5Ccdot%204%20%5Ccdot%203%20%3D%2096)
Answer:
1800
Step-by-step explanation:
(1/2)/100 of x = 9
1/2*1/100 of x = 9
1/200 of x = 9
x/200 of x = 9
x = 9*200
x = 1800
Answer:
<em>The cosine of the complementary angle to 38° is 0.62. </em>Answer: d
Explanation:
<u>Complementary Angle</u>
Two angles x and y are complementary if
x+y=90°
The complementary angle of 38° is 90°-38°= 52°
Now use a calculator to find the approximate value of
![\cos 52^\circ \approx 0.61566](https://tex.z-dn.net/?f=%5Ccos%2052%5E%5Ccirc%20%5Capprox%200.61566)
Rounding to two decimal places:
![\cos 52^\circ \approx 0.62](https://tex.z-dn.net/?f=%5Ccos%2052%5E%5Ccirc%20%5Capprox%200.62)
a. Incorrect. The cosine of 52° is not 0.68
b. Incorrect. The cosine of 52° is not -0.16
c. Incorrect. The cosine of 52° is not -0.22
d. Correct. The cosine of 52° is 0.62 to two decimal places.
Answer:
Semicircle = 353.25 cm²
Step-by-step explanation:
Area of semicircle = πr²/2
substitute the values
semi circle = 3.14 × 15 × 15 / 2
Area of semicircle = 353.25 cm²
