For each hour he babysits, Anderson earns $1 more than half of Carey’s hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey’s hourly rate, c?

Answers

Answer:

The equation is 1/2c + 1 = 6

The answer to this equation is 10.

Step-by-step explanation:

Anderson earns $1 more, so you would put '+1' in the equation. Since it says 'half of Carey's hourly rate', you would put 1/2c in the equation. $6 is the total, so that would go on the other side of the equation, thus creating the final equation 1/2c + 1 =6.

Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
12=2+c
c=$10
Carey earns $10 hourly

What is one-third of 2,700?

Answers

2700* 1/3 = 2700 ÷ 3 = 900

help this helps!

Final answer:

To get one-third of a number, you divide that number by 3. When we divide 2,700 by 3, the result is 900. Therefore, one-third of 2,700 is 900.

Explanation:

To find a fraction of a whole number, we multiply the numerator of the fraction by the provided number and then divide the product by the denominator of the fraction.

To find one-third of a number, you can divide that number by 3.

In this case, to find one-third of 2,700, you simply divide 2,700 by 3.

The result when you divide 2,700 by 3 is 900

Therefore, one-third of 2,700 is 900.

If the diameter of a circle is 6 inches, how long is the arc subtended by an angle measuring 70°?

Answers

Answer:

Length of arc of a circle is given by:

$L = r \cdot \theta$ .....[1]

where

L is the length of an arc

r is the radius of the circle.

As per the statement:

Diameter of the circle(D) = 6 inches.

we know that:

D =2r

6 = 2r

Divide both sides by 2 we get;

3 = r

r = 3 inches

We have to find the long arc arc subtended by an angle measuring 70°.

Substitute the value of r = 3 inches and $\theta = 70^(\circ)$ in [1] we have;

$L =3 \cdot 70$

Simplify:

L = 210 inches

Therefore, 210 inches long is the arc subtended by an angle measuring 70 degree.

C = πD = π6in

Arc = D * 70°/360° = 3.1416*6*7/36=3.67 in

Find the area of the circle in terms of pi. 20mAnswers

Answers

What is the area of a circle formula?

The area of a circle formula:
$\pi r^2$

So all you have to do...
is plug in 20 for r!

$20 \pi ^2$
20 x 20 is 400.
$400 \pi$

If you don't want pi...
400 x pi is about:
1256.64

The answer is (C).

Final answer:

The area of the circle with a radius of 20m is 400π square meters.

Explanation:

The formula to find the area of a circle is π * radius2. Given that the radius is 20m, we can substitute it into the formula: Area = π * (20m)2. This simplifies to 400π m2. Therefore, the correct answer is 400π m2.
