Answer:

1st integer=x

2nd integer=x+1

3rd integer=x+2

4th integer=x+3

2(x +(x+2))= 3(x+1) +11

solve

2 (2x +2) = 3x + 3 + 11

4x + 4 = 3x + 14

-3x-4 =-3x -4

x=10

1st integer=10

2nd integer=11

3rd integer=12

4th integer=13

Step-by-step explanation:

The area of a ferris wheel is about 154 square meters. Which of the following is closest to the length of one of the spokes? [As

babunello [35]

Answer:

The length of one of the spoke is 7 m

Option C is correct answer.

Step-by-step explanation:

Area of Ferris Wheel = 154 square meters.

We need to find the length of one of the spokes.

We are given: Assume the spokes go from the centre to the edge of the Ferris wheel.

So, We are given area of circle and we need to find radius of circle.

The formula used is: $Area\:of\:circle=\pi \:r^2$

Putting values and finding radius

$Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m$

So, Radius of circle = 7 m

The length of one of the spoke is 7 m

Option C is correct answer.

Which expression is NOT equal to 125? (1 point)

DENIUS [597]

Choice 1:
= 5 * [5^3 / (2/5)]^2
= by looking at the equation, it's kinda not equal to 125

choice 2:
= [5^3 / 5^4]^-3
= 5^-9 / 5^-12
= 5^(-9 - -12)
= 5^3
= 125

choice 3:
= 5^-2 / 5^-5
= 5^(-2 - -5)
= 5^3
= 125

choice 4:
= 5 * 5^5/5^3
= 5 * 5^(5-3)
= 5 * 5^2
= 5^3
= 125

So the expression that is not equal to 125 is:
<span>5 times the quotient 5 cubed over two-fifths, raised to the second power</span>

Help asap pls i’ll appreciate it a lot !!

WARRIOR [948]

Answer:

A. 7.5 cm

Step-by-step explanation:

3/4 = (x + 3)/(2x + 1)

3(2x + 1) = 4(x + 3)

6x + 3 = 4x + 12

2x = 9

x = 4.5

BC = x + 3

= 4.5 + 3

= 7.5 cm
