Answer:there are 10 Multiple choice problems.

There are 5 open ended problems.

Step-by-step explanation:

Let x represent the number of Multiple choice problems in the test.

Let y represent the number of open ended problems in the test.

Your your math test has 15 problems. . This means that

x + y = 15

Multiple choice problems are worth four points each and open ended problems are 12 points each. The maximum number of points possible on the test is 100. This means that

4x + 12y = 100- - - - - - - - - - 1

Substituting x = 15 - y into equation 1, it becomes

4(15 - y) + 12y = 100

60 - 4y + 12y = 100

- 4y + 12y = 100 - 60

8y = 40

y = 40/8 = 5

Substituting y = 5 into x = 15 - y, it becomes

x = 15 - 5 = 10

On Saturday, many tickets for a hockey game were sold. Children and adult tickets were sold in the ratio of 4:7. There are 88 ti
Illusion [34]

Answer:

49 tickets

Step-by-step explanation:

THis is pretty straight forward

So we have the ratio 4:7

We know there were 88 tickets in total but we don’t know the exact amount of adult and kids

So we can Add up the ratio

4+7=11

Now we can divide 88 by 11

you’ll get 7

So by doing this we know there are 7 groups of the ratio for child to adults 4:7

So we just multiply the 7 to each

4*7

7*7

you’ll get 28:49

Now we know there are 28 kid tickets and 49 adult tickets

We know this is correct becuase if you add up the ratio, it’ll be 88

Which is the same as the amount fo people at the hockey game

Water flows through a pipe at a rate of 710 pints per day. Express this rate of flow in cubic feet per month. Round your answer
Snowcat [4.5K]

Answer:

356 ft³ per month.

Step-by-step explanation:

From the question,

Water flows at a rate of 710 pints per day.

We shall convert 710 pints to cubic feet (ft³).

This can be obtained as follow:

1 pint = 0.0167 ft³

Therefore,

710 pints = 710 × 0.0167 = 11.857 ft³

From the calculations made above, 710 pints is equivalent to 11.857 ft³.

Thus, we can say that water flows at a rate of 11.857 ft³ per day.

Finally, we shall determine the rate of flow of water in cubic feet per month.

Note: there are 30 days in a month.

Water flow at a rate of 11.857 ft³ per day.

Therefore, the rate of flow of water in 30 days will be = 30 × 11.857 ft³ = 356 ft³

Thus, the flow rate of water is 356 ft³ per month.
