Answer:

1400 mi

Step-by-step explanation:

The triangle CHE is right, angle CHE is marked as right angle.

We have:

CD= CH = 3960 mi
DE = 240 mi
EH = ?

Use Pythagorean theorem to find the value of EH:

CE² = CH² + EH²
CE = CD + DE = 3960 + 240 = 4200

Substitute known values and solve for EH

4200² = 3960² + EH²
EH² = 4200² - 3960²
EH² = 1958400
EH = √1958400
EH = 1399.42 ≈ 1400 mi (rounded)

The exact circumference of the circle is $7 \frac{49}{150} k m$

The approximate circumference of the circle is $7.33 k m$

Explanation:

The diameter of the circle is $2 \frac{1}{3} \mathrm{km}$

Now, we shall find the circumference of the circle.

The formula to determine the circumference of the circle is given by

$C=\pi d$

Where C is the circumference , $\pi$ is 3.14 and $d=2 \frac{1}{3} \mathrm$ is the diameter of the circle.

The exact circumference of the circle is given by

$\begin{aligned}C &=\pi d \\&=(3.14)\left(2 \frac{1}{3}\right) \\&=(3.14)\left(\frac{7}{3}\right) \\&=\frac{21.98}{3}\end{aligned}$

Multiply both numerator and denominator by 100, we get,

$C=\frac{2198}{300} \\C=\frac{1099}{150}$

Converting $\frac{1099}{150}$ into mixed fraction, we get,

$C=7 \frac{49}{150}$

Thus, the exact circumference of the circle is $7 \frac{49}{150} k m$

The approximate value of the circumference can be determined by dividing the value $\frac{1099}{150}$

$C=\frac{1099}{150}=7.327$

$C=7.33km$

Thus, the approximate circumference of the circle is $7.33 k m$

The cost of going to the big playland park for a family is given by c = 15x + 50, where c represents the cost and x represents t

marusya05 [52]

C = 15x + 50

let c be $125 since c represents the cost
15x + 50 = 125
15x = 125 - 50
15x = $75
x = 75 ÷ 15
x = 5
