==========================================

Explanation:

AB is a diameter of the circle with point O in the center. This makes angle AOB to be 180 degrees. Consequently, arc ADB makes up 180 degrees of a full 360 degree circle (ie it makes up half of the circle since 180/360 = 1/2)

We're told that arc ADB is 15pi units long. Since arc ADB makes up half the circle, the full circle must therefore be 2*15pi = 30pi. This is the circumference.

------------------

We're also told that angle COB is 60 degrees. Let's find angle COA

(angleCOA) + (angleCOB) = 180

angleCOA = 180-(angleCOB)

angleCOA = 180-60

angleCOA = 120

Angle COA is 120 degrees

This makes up 120/360 = 1/3 of the full circle

So (1/3)*(circumference) = (1/3)*(30pi) = 10pi is the arc length of AC where we take the shorter path from A to C along the circle's edge.

Answer:

AC = 10π

Step-by-step explanation:

Consider arc ADB with length 15π

ADB = circumference of circle × fraction of circle , that is

2πr × [tex]\frac{180}{360}[/tex] = 15π

2πr × [tex]\frac{1}{2}[/tex] = 15π

πr = 15π ( divide both sides by π )

r = 15

∠ AOC = 180° - 60° = 120° ( adjacent angle to 60° )

Thus

AC = 2πr × [tex]\frac{120}{360}[/tex]

     = 2π × 15 × [tex]\frac{1}{3}[/tex]

     = 30π × [tex]\frac{1}{3}[/tex]

     = 10π

Answer:

she makes 10$ an hour

Step-by-step explanation:

Jada makes 35$ after working for 5 hours.

We may determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio.

Given, Jada earns 7$ per hour mowing her neighbor's lawn. remaining data is unnecessary for the given problem.

working 1 hour Jada makes = 7

working 5 hours Jada makes = 7* 5 = 35

Therefore, $35 is money Jada makes after mowing her neighbor's lawn.

Answer:

no

Step-by-step explanation:

because 1 deciliters is 0.1 liters

The 4 deciliter milk will not fill a 1 litre bottle

From the question, the amount of milk is:

Amount = 4 deciliters

As a general rule;

1 deciliter = 0.1 liters

So, we have:

Amount = 4 * 0.1 liters

Evaluate the product

Amount = 0.4 liters

0.4 is less than 1

Hence, the milk will not fill a 1 litre bottle

Answer:

31.564

Step-by-step explanation:

The centroid (the point where the medians meet) divide each median into parts with lengths in a ratio of 2:1. This means 7x + 1 is twice the length of 3x + 4, or

7x + 1 = 2 (3x + 4)

Solve for x :

7x + 1 = 6x + 8

7x - 6x = 8 - 1

x = 7

Then XE has length

XE = 4•7 - 2 = 28 - 2 = 26

FX is twice this length, so

FX = 2•26 = 52

and so FE has length

FE = FX + XE = 52 + 26 = 78

Answer:

yes it is a rational number

Answer:

You'd distribute the 2 to everything in the parenthesis. So, you'd do 2(4x) - 2(-11), which would then be 8x - (-22) = 19. You'd then add 22 to 19 to get 41. The only thing you can do from here is divide 8x by 41 to get 41/8 = x

Answer:

It will travel 213.2 miles.

Step-by-step explanation:

Multiply 41 by 5.2

There are 213.2 miles a car travel with an average of 41 mph in 5.2 hours.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

An average speed of a car = 41 mph

And, Time taken by car = 5.2 hours

We know that;

⇒ Speed = Distance / Time

Substitute all the values, we get;

⇒ 41 = Distance / 5.2

⇒ Distance = 41 × 5.2

⇒ Distance = 213.2 miles
