Last question of the day i think so plz help

Answers

Answer:

It's 170 or C

Step-by-step explanation:

We multiply the base first, which would be 14 x 10 or 140. Then we take the top triangle, which would be (6 x 10)/2 or 30.  So then we add 30 and 140 to get 170

Answer:

170

Step-by-step explanation:

(rectangle) 14 x 10 = 140

(triangle) (6 x 10)/2 = 30

140 + 30 = 170

Brian read 2/15 of his novel in 20 minutes.
If he reads at the same rate, what portion of his novel
can he read in one hour

Answers

3/15, since he reads 2/15 of his novel in 20 minutes plus 20 to the minutes and add 2 to the fraction and go until 60 minutes = 3/15

Answer:

2/5 of their novel

Step-by-step explanation:

20 minutes is 1/3 of an hour, so 20*3 gets you an hour. Now we can do 2/15*3 because that's how many "batches" of 20 minutes there are. 2*3=6 so it would be 6/15, this would be you answer. But, we can simplify this fraction by dividing the numerator and denominator by 3. This gets you 2/5.

Raymond just got done jumping at Sky Zone. The total cost of his session was $43.24. He had to pay a $7 entrance fee and $1.25 every minute he was on the trampoline. Write an equation to determine the number of minutes (t) that Raymond was on the trampoline.

Answers

Answer:

1.25x + 7 = 43.25 :)

Step-by-step explanation:

x= how many minutes he stayed every minute

The total cost is $43.24.

We know that there is a $7.00 entrance fee so we can go ahead and subtract 7 from 43.24

43.24 - 7 = 36.24

We know that the rest of the price is the minutes that Raymond was on the trampoline. So what we will do is divide 1.25 from 36.24

36.24 ÷ 1.25 = 28.992

We will round up 28.992 to 29.00

so we can say that Raymond was jumping on the trampoline for about 30 minutes for a total of $43.24.

The number of lime-flavored candies in a candy machine is 85. If this is
17% of the number of candies in the machine. How many candies are in the
machine?

Answers

the answer is:500

step by step explanation: i don't know if i'm right by the way

500

Percent means per hundred.

Therefore,

17% = 17/100 = 0.17

Let the total number of gumballs be n. Then

17% of n = 85 means that

0.17 x n = 85

n = 85/0.17 = 500
