Answer:

15 mL of 100% vinegar
45 mL of Italian dressing

Step-by-step explanation:

Let v represent the amount of 100% vinegar to be included in the mixture. Then the amount of vinegar in the overall mixture is ...

1.00v + 0.08(60 -v) = 0.31(60)

0.92v = 60(0.23) . . . . . . . collect terms, subtract .08(60)

v = 60(0.23/0.92) = 15 . . . mL of vinegar

60 -v = 45 . . . mL of dressing

15 mL of vinegar and 45 mL of Italian dressing should be used.

Question 9 of 2

Company A charges a $125 annual fee plus $7 per hour car share fee.

Company B charges $110 plus $10 per hour. The minimum number of hours that a car share needs to be used per year to make company A a better deal is 6 hours.

A: y=125+7 x

B: y=110+10 x

for A to be a better deal than B, 125+7 x<110+10 x has to be true

subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3 x

divide by 3: 5<x

so x has to be greater than 5 , im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you.

Equations are not always balanced on both sides using a "equal to" symbol in mathematics. Sometimes it can be about a "not equal to" relationship, meaning that something is superior to or inferior to another. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms.

Vika [28.1K]

Given that average mass of an ant $= 3 \times 10^{-3}$ grams.

Given that average mass of a giraffe $= 2 \times 10^{3}$ Kilograms.

Now we have to find about how many times more mass does a giraffe have than an ant. Before carring out any comparision, we must make both units equal.

Like convert kilogram into gram or gram into kilogram.

I'm going to convert kilogram into gram using formula

1 Kg = 1000 g

So the average mass of a giraffe $= 2 \times 10^{3} *10^3$ grams.
