Juan always saves the same amount from his weekly allowance. The table shows how much he has saved at different times.

erastova [34]

On the 14 week Juan will save $ 52 because each 3 week he earns 3.
So you do 9 divide by 3 and get 3. Then you do 3 times 2 and get 6.
46 + 6 = 52

The distance from Earth to the moon is 2.4 × 105 miles. The distance from Earth to the sun is 9.3 × 107 miles. Complete the sent

Liono4ka [1.6K]

Answer:

$Distance = 9.276 * 10^7$ miles

Step-by-step explanation:

Given

$Earth\ to\ Moon = 2.4 * 10^5 miles$

$Earth\ to\ Sun = 9.3 * 10^7 miles$

Required

Difference in the distance of earth to sun to the distance of earth to moon

This can be solved using:

$Distance = Earth\ to\ Sun - Earth\ to\ Moon$

$Distance = 9.3 * 10^7 - 2.4 * 10^5$

Express 10⁷ as 10⁵ * 10²

$Distance = 9.3 * 10^5 * 10^2 - 2.4 * 10^5$

Factorize:

$Distance = 10^5(9.3 * 10^2 - 2.4)$

Solve the expression in the bracket

$Distance = 10^5(9.3 * 100 - 2.4)$

$Distance = 10^5(930 - 2.4)$

$Distance = 10^5(927.6)$

$Distance = 927.6 * 10^5$

Expand 927.6

$Distance = 9.276 * 10^2 * 10^5$

$Distance = 9.276 * 10^{2+5}$

$Distance = 9.276 * 10^7$

An airplane can cruise at 570 mph. How far can it fly in 4/3 hours?

cestrela7 [59]

Answer:

The plane can fly 760 miles in 4/3 hours.

Step-by-step explanation:

Given that:

An airplane can cruise at 570 miles per hour.

We have to find the distance travelled by train in 4/3 hours.

Distance = Speed * Time

Distance = $570*\frac{4}{3}$

Distance = $\frac{2280}{3}$

Distance = 760 miles

Hence,

The plane can fly 760 miles in 4/3 hours.
