A circle has a circumference of 7,850 units. What is the radius of the circle

Snezhnost [94]

Answer: Radius = 1,250

Step-by-step explanation: The circumference of a circle equals the 2 x radius x π.

The formula to solve the radius is 2r x 3.14 = 7,850

Divide both sides by 3.14 = 2r = 2,500

Divide both sides by 2 = r = 1,250.

The radius = 1,250

A certain insect can beat its wings 120 times per second write an equation in slope intercept from that shows the relationship b

dalvyx [7]

Answer:

The relationship between flying time in seconds in the number of times the insect beats its wings:

y = 120x

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the rate of change or slope

b is the y-intercept

In our case,

Let 'x' be the flying time in seconds

Ley 'y' be the number of times the insect beats its wings

Given that a certain insect can beat its wings 120 times per second.

It indicates that the rate of change or slope = m = 120

In our case the y-intercept b = 0, as there is no initial condition mentioned here.

Now, substituting m = 120 and b = 0 in the slope-intercept form

y = mx+b

y = 120x+0

y = 120x

Therefore, the relationship between flying time in seconds in the number of times the insect beats its wings:

y = 120x

A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a

Dafna1 [17]

Answer:

The nomber of people can attend a dinner that costs $131. 50 is 14.

Step-by-step explanation:

With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:

c=16+8.25x, where:

c is the total cost of he dinner

x is the number of people

Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:

131.50=16+8.25x

131.50-16=8.25x

115.50=8.25x

x=115.50/8.25

x=14

According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.

Solve the following equation for x.<br><br> 12x^2-36x=0

OlgaM077 [116]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve for x ~

$\qquad \sf \dashrightarrow \:12 {x}^{2} - 36x = 0$

$\qquad \sf \dashrightarrow \:12 x({x}^{} - 3) = 0$

$\qquad \sf \dashrightarrow \:12x = 0 \: \: or \: \: x - 3 = 0$

$\qquad \sf \dashrightarrow \:x = 0 \: \: or \: \: x = 3$

Therefore, the possible values of x are 0 and 3
