8 miles in 40 minutes = 12 miles per hour

5 miles in 30 minutes = 10 miles per hour

workings

60/40=1.5

1.5x8=12

60/30=2

2x5=10

method

you divide the 60 by however many minutes, then times that by the amount of miles

If side A is twice as long as B and C is 25 using the Pythagorean Theorem,What are the lengths of side A and B? Round to the nea

777dan777 [17]

Answer:

The lengths of side A is 22.4 and B is 11.9.

Step-by-step explanation:

Given:

If side A is twice as long as B and C is 25 using the Pythagorean Theorem.

Now, to find the lengths of side A and B.

Let the side B be $x.$

So, the side A be $2x.$

Side C = 25.

Now, to solve by using Pythagorean Theorem:

A² + B² = C²

$(2x)^2+(x)^2=(25)^2$

$4x^2+x^2=625$

$5x^2=625$

Dividing both sides by 5 we get:

$x^2=125$

Using square root on both sides we get:

$x=11.18.$

B rounding to the nearest tenth = 11.9.

Now, to get A by substituting the value of $x$ :

$2x\\=2\times 11.18\\=22.36.$

A rounding to the nearest tenth = 22.4.

Therefore, the lengths of side A is 22.4 and B is 11.9.

48 divided by four fifths

Fed [463]

Answer:

The answer is 60.

Step-by-step explanation:

$\frac{48}{1}$ ÷ $\frac{4}{5}$

Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):

$\frac{48}{1}$ × $\frac{5}{4}$

Cross-cancel(common factor of 4):

$\frac{12}{1}$ × $\frac{5}{1}$

Multiply:

$\frac{12 x 5}{1 x 1}$

Simplify:

12 x 5=60

The answer is 60

hope this helps :)
