As an estimation we are told 5 miles is 8 km. Convert 70 miles to km. km

Lena [83]

Answer: 112 km

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

Work Shown:

(5 miles)/(8 km) = (70 miles)/(x km)

5/8 = 70/x

5*x = 8*70 ... cross multiply

5x = 560

x = 560/5 .... divide both sides by 5

x = 112

According to the given estimation, 70 miles converts to 112 km.

The more accurate conversion is approximately 70 miles = 112.65408 km, so this estimation isn't too far off.

Genrish500 [490]

Answer:

50.24 in

Step-by-step explanation:

to find how far it it will go you will need to find the circumference and times it by 2 to find the circumference the formula is 2*pi*radius so you would do 2*3.14*4 and that is 25.12 but since it is 2 revolutions you times 25.12 by 2

Use the diagram and the Pythagorean Theorem to find the EXACT area of square ABCD

Burka [1]

ANSWER

The area of square ABCD is
$25 \: square \: unit$

EXPLANATION

The area of square ABCD is the square of the length of one side.

That is the area of ABCD is |AD|²

From Pythagoras theorem,

${|AD|}^{2} = { |AG| }^{2} + { |GD| }^{2}$

We can read from the graph that, each box is one unit.

This implies that,

${|AD|}^{2} = {4}^{2} + {3}^{2}$

${|AD|}^{2} =16 + 9$

${|AD|}^{2} =25$

Therefore the area of square ABCD is 25 square units.

The correct answer is option C.
