Over the last three evenings, Rita received a total of 91 phone calls at the call center. The third evening, she received 2 time

tatyana61 [14]

Rita received 24 phone calls on the first evening, and 19 phone calls on the second evening and 48 phone calls on the third evening at the call center.

Step-by-step explanation:

As per given details,

Rita received a total of 91 phone calls at the call center over the last three evenings.

Let us assume the number of phone calls Rita received in the first evening is X.

The second evening Rita received 5 fewer calls than the first evening

=>X-5

The third evening Rita received 2 times as any calls as the first evening

=>2X

Now as given sum of total number of calls received in the three evenings is

X + X-5 + 2X = 91

4X - 5 = 91

4X = 96

X =24.

Therefore total calls received on first evening is X = 24

On the second evening X-5 = 24-5 = 19

On the third evening 2X = 48.

$\huge\green{ \mid{ \underline{ \overline{ \tt ♡ ANSWER ♡ }} \mid}}$

$x = 40$

$(6 - 2x)(3 - 2x) \\ =( 6 - 2 \times 40)(3 - 2 \times 40) \\ = (6 - 80)(3 - 80) \\ = - 74 \times - 77 \\ = 5698$

60 students study a language at a school.

nirvana33 [79]

The answer will be that out of 36 boys 24 speak french and 12 speak german and out of 24 girls 16 speak french and 8 speak german.

<h3>What is the frequency tree?</h3>

In the question we have that there are 60 students in total out of which 36 are boys:

So number of the girls will be = 60-36=24

Now if 2/3 of the boys speak french the number of the boys who speak french will be = (2÷3)x36=24

Now the number of the boys who speak german will be =36-24=12

Now since 40 students study french so we have the number of the boys who speak french is 24. so the number if the girls who speak french will be =40-24=16

Since there are 24 girls in total and out of them 16 speak french so the remaining girls speak german=24-16=8

Hence answer will be that out of 36 boys 24 speak french and 12 speak german and out of 24 girls 16 speak french and 8 speak german.
