Grade 5 and 6 collect 12 times as many cans as grades 1 and 2. Grades 3 and 4 I collect 6683 cans, and that amount is 2389 cans less than great 5 and 6. How many cans are collected by grades 5 and 6?

Answers

Answer 1
Answer:

Answer: 9072

Step-by-step explanation:

It seems that the number of cans that grades 1 and 2 collect are irrelevant in the problem so you can basically ignore that. Grades 3 and 4 have 6683 cans which is 2389 cans less than grades 5 and 6 so that means grades 5 and 6 have 2389 cans more than 6683. Now you just add 6683 and 2389 to find the cans that grades 5 and 6 have.

6683 + 2389 =  9072

Grades 5 and 6 have 9072 cans

Someone help me on this.

Answers

Answer:

-57-39i

Step-by-step explanation:

So we have the expression:

(7+2i)(-9-3i)

FOIL:

=7(-9)+7(-3i)+2i(-9)+2i(-3i)

Simplify:

=-63-21i-18i-6i^2

Recall that i² is just -1. Thus:

=-63-21i-18i-6(-1)

Simplify:

=-63-21i-18i+6

Combine like terms:

=(-63+6)+(-21i-18i)

Add:

=-57-39i

If the ratio of boys to girls at the school is 2:5 and there are 40 boys how many girls are there?

Answers

The total number of students in school is 140 and number of girls at the school is equal to 100.

What do you mean by ratio ?

Ratio is the quantitative relationship between two values indicating how frequently one value contains or is contained within the other.

It is given that the ratio of boys to girls at the school is 2:5.

Let's assume the total number of students in school is x.

We now need to find the number of girls in the school but before that we must try to find the total number of students in the school.

Sum of ratios = 2 + 5 = 7

It is given that there are 40 boys in students.

2/7 of the total number of students are boys.

i.e., the expression can be written as :

2x / 7 = 40

2x = 40 × 7

2x = 280

x = 140

The total number of students in school is 140.

So , the number of girls in school is :

= 140 - 40

= 100

There are 100 girls in the school.

Therefore , the total number of students in school is 140 and number of girls at the school is equal to 100.

Answer:

100 girls

Step-by-step explanation:

The ratio of boys : girls is 2 : 5.

In other words, boys are 2 parts of the school while girls are 5 parts of the school.

Since there are 40 boys, 2 parts of the school is 40. Thus:

2p = 40\np = 20

1 part is 20.

Since there are 5 parts girls, there are

5p = 5*20 = 100

100 girls.

Answer: 100 girls
