Sophie has a doll collection with 36 dolls. She decides to sell s dolls to a museum and has r dolls remaining.
What is the independent variable?

Answers

Answer 1
R dolls is the independent variable

The independent variable is R dolls because the amount of dolls you have controls how many dolls you can sell. If you sell all of your dolls you can no longer sell and you’ll no longer have dolls. This means R is x (Independent variable) and S is y (Independent variable.
Answer 2
R dolls would be independent because that number controls the amount of dolls that you can sell.

D. The solid figure can be broken into rectangles, it’s dimensions would be 24mx0.4m
E. To find how much concrete is needed you have to...
multiply LxWxH
So multiply 1.8x1.2x2.4=5.184
Then divide 1.8 by 3= 0.6
Each small rectangle is 0.6 m in height
5.184-1.8=3.384

Truman is buying a teddy bear and flowers for his girIfriend. Flowers Galore charges $13 for the teddy bear and $0.75 per flower. Famous Florist charges $9 for the teddy bear and $1.25 per flower. Which inequality represents the number of flowers, f, Truman would need to buy to make Flowers Galore the cheaper option?

Answers

the answers is either f < 2 or f > 2

The inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f

How to determine the inequality?

At Flowers Galore, we have:

Teddy bear = $13

Flower = $0.75

At Famous Florist, we have:

Teddy bear = $9

Flower = $1.25

So, the expressions are:

Flowers Galore: 13 + 0.75f

Famous Florist: 9 + 1.25f

When Flowers Galore is the cheaper option, we have:

13 + 0.75f < 9 + 1.25f

Hence, the inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f
