Answer: A) 264ft/minute

Step-by-step explanation:

1. Based on the information given in the problem, the speed of the track runner was 3 miles per hour ( $3\frac{mi}{h}$ ).

2. If you want to know the speed of the track runner in feet per minute, you need to apply the following proccedure:

$(3\frac{mi}{h})(\frac{5280ft}{1mi})(\frac{1h}{60min})=\frac{(3)(5280)}{60}=264\frac{ft}{min}$

3. Therefore, the answer is the option A.

a village having a population of 4000, requires 150 litres of water per head per day. it has a tank measuring 20m x 15m x 6m. fo

allochka39001 [22]

The water will last for 3 days

Solution:

Given that, village having a population of 4000, requires 150 litres of water per head per day

Let us first find the volume of tank

The tank measuring 20m x 15m x 6m

Length = 20 m

Breadth = 15 m

Height = 6 m

$volume\ of\ tank = length \times breadth \times height$

$Volume\ of\ tank = 20 \times 15 \times 6 = 1800$

Thus volume of tank is 1800 cubic meter

From given,

Water required per person per day = 150 liters

Therefore, water required for 4000 people per day is:

$\rightarrow 4000 \times 150 = 600000 \text{ liters }$

Convert to meters

$600000 \text{ liters } = 600000 \times \frac{1}{1000}\ m^3\\\\600000 \text{ liters } = 600\ m^3$

How many days will the water of this tank last?

$\text{Number of days water will last } = \frac{\text{volume of tank}}{\text{total water required per day}}$

$\text{Number of days water will last } = \frac{1800}{600} = 3$

Thus the water will last for 3 days

Someone please answer this correctly!!

Luda [366]

Answer:

1.98 × 10^10

Step-by-step explanation:

First solve for how many text messages were sent out per one month:

22,000,000 × 900

19,800,000,000

Convert into scientific notation:

1.98 × 10^10

In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.

What would the equation be for d=0.68t + 1.5

frozen [14]

Answer:

Step-by-step explanation:

d=0.68t + 1.5 if t time is 3 hrs

d=0.68(3) + 1.5

= 2.04 + 1.5

d= 3.54 ft

d=0.68t + 1.5 if d depth is 4 ft solve for t

d - 1.5 = 0.68t

(d - 1.5) / 0.68 = t

(4 - 1.5) / 0.68 = t

t = 2.5/0.68

t = 3.68 ft
