When a number is decreased by 8.5%, the result is 33. What is the original number to the nearest tenth?

Reil [10]

Answer:

Step-by-step explanation:

Let the original number be x

(100-8.5)% of x = 33

91.5% of x = 33

$\frac{91.5}{100}x=33\\\\x=33*\frac{100}{91.5}\\\\x=36.07$

x= 36.1

Wheel A has a diameter of 25.4 inches. Wheel B has a diameter of 22.5 inches. About how much farther will Wheel A travel in one

MissTica

Wheel A will travel a distance of approximately 9 in more than wheel B in one rotation.

<u>Explanation:</u>

Given:

Diameter of wheel A, d₁ = 25.4 in

Radius of wheel A, r₁ = 12.7 in

Diameter of wheel B = 22.5 in

Radius of Wheel B, d₂ = 11.25 in

Distance travelled by A = ?

In one rotation, the distance travelled by a wheel is equal to its circumference.

Circumference of a wheel = 2πr

Circumference of wheel A = 2πr₁

= 2 X 3.14 X 12.7 in

= 80 in

Circumference of wheel B = 2πr₂

= 2 X 3.14 X 11.25 in

= 71 in

Therefore, wheel A will travel a distance of approximately 9 (80 - 71 in) in more than wheel B in one rotation.

The transportation department has to put a railing along the outer curve of this road. The road is 20 feet wide. What is the len

Dovator [93]

From my research, the image attached supports the problem. Since only the outer curve is to be solved for, the formula for arcs can be used.

s = theta*radius

where s = arc length = outer curve

theta = 70 (pi/180)
radius = 70

s = 70 * (70*pi/180)
s = 85.52 feet

Therefore, the outer curve is 85.52 feet long
