Water flows into a tank at the rate of 3 litres per minute.
a. If the tank fills completely in 450 seconds what is the capacity of the tank in ml?

A hole is drilled in the bottom of the tank. Water flows out of the hole at a rate of 60 ml per second.
b. How long will the tank take to drain completely if the flow of water IN continues at the same rate?

Answers

Answer 1

Answer:

a) 22,500  b) 2250 seconds (or 37.5 minutes)

Step-by-step explanation:

a) There are 1000 ml in a liter.

Therefore, the rate of water flowing in can be 3000 ml per minute. To convert this into per second, we divide 3000 by 60.

This becomes 50 ml per second. If the tank fills in completely in 450 seconds,  we multiply 50 by 450 to get how much water in ml was used to fill the tank completely. 50 times 450 = 22,500. Therefore, the capacity of the tank is 22,500.

b) Since water keeps flowing into the tank at a rate of 50 ml per second, and water flows out at a rate of 60 ml per second, we can define the rate flowing out of the tank as 10 ml per second.

Because the maximum capacity of the tank is 22,500 ml, we divide this by 10 ml (the rate flowing out) to get how many seconds it will take for the tank to drain out completely. 22,500 divided by 10 is 2250.

So, it will take 2250 seconds for the tank to drain completely. In minutes, this becomes 37.5 minutes.

A baseball diamond is a square that is 90 feet on each side. What is the distance a catcher has to throw the ball from home to second base?

Answers

Omg I did this like one month ago. Okay so first draw a square and mark 90 on each side. Then draw a diagonal line. You are left with 2 triangles. Now you have to do a2+ b2= c2
So 90 squared + 90 squared = c2
90 x 90= 8100 x 2 is equal to 16200.
16200= c2
The square root of 16200 is about 127.27 feet. That’s the answer

Rewrite the sum of 96 + 80 using the distrubutive property

Answers

Yes I have the same problem with my phone I think it’s 190
96+80 is just 176 but we need to do the distributive properties. So distributive properties for example at a(b+c) but we need ours to equal 176. Let’s pick an a value, let’s say 4 so 4(b+c)=176. A quarter of 176 is 44, so b+c =44. B has to stay as a variable. Let’s say b= 30. C would be 14. So 4(b+14) would be a distributive property for 96+80

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A salesman earns 60% commission on all the merchandise that he sells. Last month he sold $800 worth of merchandise.

So, the Commission he earns

= 800 + 800 x 60%

= 800 + 800 x 60/100

= 800 + 480

= 1280

Hence, the commission is $480.

What is the equation of the line that passes through the point (- 3, 1) and has a slope of 2/3?

Answers

Step-by-step explanation:

Equation of a line passing through a point (h, k) and slope 'm' will be,

y - k = m(x - h)

If this line passes through a point (-3, 1) and has a slope 2/3 32 .

Therefore, equation of the line will be,

y-1=2/3(x+3)y−1=32(x+3)

y=2/3+2+1y=32x+2+1

y=2/3 x+3y=32x+3

Therefore, equation of the line will be,

y=2/3x+3y=32x+3

One-eighth of the parts tooled by a machine are rejects. How many parts were tooled
*437 parts were rejected?

Answers

There were 3,496 parts in total that were tooled by the machine.

Assuming the total number of parts tooled is x, that means that 1/8 of x is 437 parts because that was the proportion of the total that was rejected.

To find the total number of parts therefore, use the formula:

Proportion of rejects × x = Number of parts rejected

1/8 × x = 437

1/8x = 437

x = 437 ÷ 1/8

x = 437 x 8

x = 3,496 parts

In conclusion, there was 3,496 parts.

the equation is

x + 0.25 = 15.75

by subtracting 0.25 from both sides we get

x = 15.75 - 0.25 = 15.50

so, her hourly wage before the raise was $15.50.

she got a raise less than $1/ hour, so her new hourly wage should be less than $15.50 + $1 = $16.50. her new hourly wage of $15.75 is less than $16.50, so the answer is reasonable.
