Answer: $403.75
Step-by-step explanation:
Cost price= $475
Discount percent= 15%
Discount = 15% of 475
= 15/100 × 475
= 0.15 × 475
= $71.25
To get the reduced price of the keyboard, we subtract the discount from the cost price of the keyboard.
= Cost price - discount
= $475 - $71.25
= $403.75
The reduced price of the keyboard is $403.75
9.55 as a mixed number would be 9 11/20.
9.55 = 9 55/100 = 9 11/20

Answer:
Option (c) is correct.
The value of x is 9.
Step-by-step explanation:
Given : Two angles are complementary. They have measures of (7x + 2)° and (3x – 2)°, respectively.
We have to find the value of x.
Two angles are said to be complementary if the sum of measure of angle is 90°.
Given (7x + 2)° and (3x – 2)° are complementary angles.
That is sum of (7x + 2)° and (3x – 2)° is 90°
⇒ (7x + 2)° + (3x – 2)° = 90°
⇒ 7x + 2 + 3x - 2 = 90
⇒ 10x = 90
⇒ x = 9
Thus, the value of x is 9.
Hence, option (c) is correct.
The volume of the larger cylinder is 250Pi.
We have given that,
The ratio of the radii of two similar cylinders is 3:5. The volume of the smaller cylinder is 54pi cubic centimeters.
We have to determine the volume of the larger cylinder.
The formula to calculate the volume of a cylinder is given by the product of base area and its height.
5/3 = 1.66667
1.666666^3=4.6296 (Volume is measured in cubic units)
54x4.6396=250
250 x pi = 250Pi.

Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
