Answer:

233.3 cubic units

Step-by-step explanation:

Volume of a pyramid

=  \frac{1}{3} × base area × height

The volume of the pyramid

=  \frac{1}{3}  \times (10 \times 10) \times 7

= \frac{1}{3}  \times 100 \times 7

= 233.333...

= 233.3 cubic units (rounded to the nearest tenth)

Delisile spends 30% of her income on rent and 50%of the remaining on food and travelling. she pays R2200,00 per month for educat
DIA [1.3K]

The total monthly income of Delisile including her spendings is R 1,520,000

<h3>How to find Delisile monthly income</h3>

Given:

  • x = Total monthly income

  • Amount spent on rent = 39% of x

= 0.30x

Amount remaining = x - 0.30x

= 0.70x

Amount spent on food and traveling = 50% of 0.70x

= 0.50 × 0.70x

= 0.35x

  • Amount spent on education = R 220,000

  • Amount left = R 312,000

Total = rent + food + education + amount left

x = 0.30x + 0.35x + 220,000 + 312,000

x = 0.65x + 532,000

x - 0.65x = 532,000

0.35x = 532,000

x = R 1,520,000

C)<br> A bus drives for 3/2 hours at an average speed of 56 mph.<br> How far does the bus drive?
natta225 [31]

Answer:

The bus drives 84 miles

Step-by-step explanation:

The question relates to relationship between average speed and time

The given parameters are;

The time duration in which the bus drives = 3/2 hours = 1.5 hours

The average speed of the bus = 56 mph

The formula average speed is given as follows;

Average \ speed = \dfrac{The \ total \ distance \ driven}{The \ time \ duration \ of \ travel}

Therefore, we have;

The total distance driven = Average speed × The time duration of travel

The total distance driven = The distance the bus drives

Substituting the given values, gives;

The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles

The distance the bus drives = 84 miles.

muminat

Answer:

Ramp

Step-by-step explanation:

A ramp is easier for a person to go up or down on because it is just higher sloped ground. For a person with crutches, a ramp does not have any abnormal steps for them to try and get over with one leg.
