Answer:
Step-by-step explanation:
<u>With 22% decrease the value after the year is:</u>
- 100% - 22% = 78% of the current value
To find 78% we need to multiply the current value by 0.78.
The same number is multiplied each year to find the decreased value.
<u>The formula for the car would be:</u>
The decay factor is 0.78
Correct choice is B
First find the volume of the cylinder.
The formula is: V=πr²h
Plug the numbers in the figure into the formula.
V=πr²h
V=π×3²×10
V=π×9×10
V=π90
V=282.743
Therefore, the volume of the cylinder is approximately 282.7in³
Find the volume of the rectangluar prism.
V=lwh
V=12×7×4
V=84×4
V=336
Therefore, the volume of the rectangular prism is 336in³
Add the volumes:
282.7+336=618.7
The volume of the composite solid is approximately 618.7in^3
Answer:
16
Step-by-step explanation:
4x3x2=24
2x2x2=8
24-8=16
From the given triangle in the photo, the lengths of the sides are 3m and a, the hypotenuse is c. One angle, opposite of 3m is given to be 50 degrees C. The right equation that would solve c is,
sin (50 degrees C) = 3m / c
Thus, the answer is the first choice.
