Answer:

x=5

AOB = 8

BOC = 13

AOC = 21

Step-by-step explanation:

<em>Angle AOB and Angle BOC is equal to Angle AOC.</em>

AOB = x+3

BOC = 4x-7

AOC= 2x+11

AOB + BOC = AOC

x+3+4x-7 = 2x+11

5x-4 = 2x+11

3x = 15

x = 5

Therefore, the value of x is 5.

<em>Angle AOB = x+3</em>

AOB = 5+3

AOB = 8

<em>Angle BOC = 4x-7</em>

BOC = 4(5)-7

BOC = 13

<em>Angle AOC = 2x+11</em>

AOC = 2(5)+11

AOC = 21

Answer:

x=5

$\angle AOC=21$

$\angle AOB=8$

$\angle BOC=13$

Step-by-step explanation:

We are given that

$\angle AOB=x+3$

$\angle AOC=2x+11$

$\angle BOC=4x-7$

We have to solve for x and find the angle measures

$\angle AOC=\angle AOB+\angle BOC$

$2x+11=x+3+4x-7$

$2x+11=5x-4$

$11+4=5x-2x$

$15=3x$

$x=\frac{15}{3}=5$

Substitute the value of x then, we get

$\angle AOC=2(5)+11=21$

$\angle AOB=5+3=8$

$\angle BOC=4(5)-7=13$

Find the diameter of the wheel. 0.6ft

s344n2d4d5 [400]

Answer:

Diameter of the wheel = 1.2 feet

Step-by-step explanation:

Radius of a wheel = Distance between a point on the circumference and the center of the circle

Diameter of a wheel = 2(radius of the circle)

= 2(0.6)

= 1.2 feet

Therefore, diameter of the wheel is 1.2 feet.

Michael has a set of 24 math problems to do for homework. Michael completed 1/4 of his homework in 3/4 of an hour. If he continu

gtnhenbr [62]

Given:

Total number of problems = 24

Michael completed $\dfrac{1}{4}$ of his homework in $\dfrac{3}{4}$ of an hour.

To find:

What fraction of his homework would he complete in one hour.

Solution:

We have,

Part of work done in $\dfrac{3}{4}$ of an hour $=\dfrac{1}{4}$

Part of work done in an hour $=\dfrac{4}{3}\times \dfrac{1}{4}$

$=\dfrac{1}{3}$

Therefore, he complete $\dfrac{1}{3}$ of his homework in 1 hour. Hence, all options are incorrect.

circle a has a circumference 2 2/3 m. Circle B has a diameter that is 1 1/2 times long as circles a’s diameter. What is the circ

White raven [17]

Answer:

Circumference of circle B,

$C_{b}=4\ m$

Step-by-step explanation:

Given:

Let,

Circumference of circle A be Cₐ =2 2/3

∴ $C_{a} =2\frac{2}{3} \\C_{a} =\frac{8}{3}$

Radius of circle A be, rₐ

Radius of circle B be, $r_{b}=1\frac{1}{2}\times r_{a}=\frac{3}{2}\times r_{a}$

To Find:

Circumference of circle B,

$C_{b}=?$

Solution:

We have Formula for Circumference.

$Circumference=2\pi \times radius$

∴ Cₐ = 2 × π × rₐ

∴ $\frac{8}{3}=2\pi\times r_{a}\\ \\\therefore r_{a}=\frac{4}{3\pi}$

Now

Circumference of circle B,

$C_{b}=2\pi\times r_{b}\\\\But\ r_{b}=\frac{3}{2}r_{a}\\ \\\therefore C_{b}=2\pi\times \frac{3}{2}r_{a}\\\\Put\ r_{a}=\frac{4}{3\pi} \\\\\therefore C_{b}=2\pi\times \frac{3}{2}\times \frac{4}{3\pi}\\\\\\\therefore C_{b}=4\ m$

Therefore, Circumference of circle B,

$C_{b}=4\ m$

How do you divide fractions?

Kaylis [27]

First flip the 2nd number. (denominator becomes numerator and vice versa) then multiply the numerators and multiply the denominators. that's the answer.
