What is the total height of all the plants?

Answers

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

1 1/2 = 1 4/8

1 1/2 = 1 4/8

5/8 =     5/8

3/4 =     6/8

1/4 =      2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8

Out of the 25 students in Mrs. Coulter's class, 15 are girls. In the school there are 390 boys. If the ratio of boys to students in Mrs. Coulter's class is proportional to the ratio of the number of boys in the school to the total number of students in the school, how many students are at the school?

Answers

Answer:

975 students

Step-by-step explanation:

This is a dense question. Let's look at it piece by piece:

1. The ratio of boys to students in the class is 10/25. If there are 25 students and 15 girls, that leaves 10 boys.

2. The question says that the ratio is in proportion of boys to total students in the school. "In proportion" in this case means that if we convert 10/25 to a fraction with numerator 390, the denominator is the amount of students in school.

3. 10x39=390. What you do the numerator you must do to the denominator: 25x39=975.

4. This means 975 students go to the school.

How do I solve this problem for 7th grade!

Answers

Its 55

35% = 35/100
So 35/100*200 <- 200 is the number of all tags
When you do this, you’ll get 70
So 70 tags are blue

Next, to find how many yellow tags, just
3/8*200 = 75
There’s 75 yellow tags

If you add both amounts (70+75) you’ll get 145

Now we know there are 200 tags and 145 of them are yellow and blue, so the rest are red
200-145 =55

Answer:

55 name tags are red

From the set {37, 50, 63}, use substitution to determine which value of x makes the inequality true.
[tex]x - 13 > 37[/tex]



A. 50

B. 37

C. 63

D. none of these

Answers

50 - 37 = 37 (doesn’t make the inequality true, since it equals 37)

37 - 13 = 24 (doesn’t make the inequality true since it’s less than 37)

63 - 13 = 50 (this is correct because your answer is greater than 37)

Answer: C
37-13 is less than 37 50-13 is equal too 37 so c is the answer
