No directions are given but I assume you want the given sentence in algebraic form.

Let c = cars

Increase here means to add.

Answer: c + 9

Suppose P varies directly with q and that P=36 when q=9 . What is the value of P when q=3?

Yuri [45]

Answer:

P=12

Step-by-step explanation:

Since P=36 and q=9, this looks like a ratio of 4:1. So if q=3, multiply that value by 4 to get your answer

Nick has fraction 1 over 2 cup of syrup. He uses fraction 1 over 6 cup of syrup to make a bowl of granola.

SCORPION-xisa [38]

Part A) How many bowls of granola can Nick make with fraction 1 over 2 cup of syrup?

So if we have 1/2 cup of syrup and 1/6 is needed we can divide 1/2 by 1/6 to find our answer for part a.

1/2 / 1/6

"keep change flip" -> 1/2 x 6

answer -> 3

He can make 3 bowls of granola

Part B) On your own paper, draw a fraction model that shows the total number of bowls of granola that Nick can make with fraction 1 over 2 cup of syrup. Make sure to label the model. Below, explain your model in detail to describe how this model visually shows the solution for Part A.

(visual attatched)

You could say "This model visually shows the solution for Part A because each bowl of granola has 1/6 cup of syrup in it. The 1/2 cup is split into 3 different parts, as you can see"

(draw it neater though, it's hard on a computer with a mouse haha)

(second problem you commented)

Part A: How many 3 over 4 foot pieces can Clark cut from the 7 and 1 over 2 feet of wire? Show your work. (5 points)

First let us change 7 1/2 into an improper fractoin,

7 x 2 = 14 + 1 = 15/2

So then we can, as we did above, divide 15/2 by 3/4 which looks like:

15/2 / 3/4

keep, change, flip -> 15/2 x 4/3

60 / 6

answer -> 10

Clarck can cut 10 3/4 foot pieces.

Part B: Using the information in Part A, interpret the meaning of the quotient in terms of the two fractions given.

*I am honestly kind of confused by this question, so here is some words that are hopefully somewhat correct*

You could say here that "Calrck had 7 1/2 feet of wire. He needed 3/4 pieces, so when he cut it up he got 10 pieces. This is because 3/4 times 10 is 7 1/2 so this quotient makes sense with the two fractions given."

Hopefully these are correct and help, have a nice day! :D

Ava bought a 250-ml bottle of concentrated

Reil [10]

Answer:

Ava needs to add 50ml of cleaner.

Step-by-step explanation:

Ratio of cleaner : water = 1:7

This means that the total ratio;(water+cleaner) = 1+7 = 8

Find fraction of each item out of the total ratio of 8;

Fraction of water = $\frac{7}{8}$

Fraction of cleaner = $\frac{1}{8}$

Knowing the fractions, find the quantity of cleaner in ml out of a total of 400-ml;

Cleaner = (1/8 )*400 = 50ml

Therefore, Ava needs to add 50ml of cleaner.
