Use the hundredths grid to answer the question.

professor190 [17]

The question is an illustration of multiplication model.

The multiplication model is: $\mathbf{0.90 \times 0.10 =0.09}$

From the figure, the shaded portions are:

$\mathbf{Green = \frac{90}{100}}$

$\mathbf{Orange = \frac{10}{100}}$

So, the multiplication model represents:

$\mathbf{Model =Green \times Orange}$

This gives

$\mathbf{Model =\frac{90}{100} \times \frac{10}{100}}$

Express as decimal

$\mathbf{Model =0.90 \times 0.10}$

$\mathbf{Model =0.09}$

Hence, the multiplication model is:

$\mathbf{0.90 \times 0.10 =0.09}$

the graph shows your budget and the total cost of x gallons of gasoline and a car wash you want to determine the possible amount

Yuki888 [10]

Answer:

Part a) The budget is $40

Part b) The cost of one gallon of gasoline is $3.55 and the cost of the car wash is $8

Part c) $x \leq 9.01\ gal$

Part d) see the explanation

Step-by-step explanation:

The complete question in the attached figure

Part a) What is your budget?

The budget is given by the equation

y=40

therefore

The budget is $40

Part b) How much does a gallon of gasoline cost? how much does a car wash cost?

Let

y ------> the cost of a gallon of gasoline plus the cost of a car wash

x -----> the amount of gasoline in gallons

we have

y=3.55x+8

In this problem

For x=0

y=3.55(0)+8=8

The y-intercept is the cost of the car wash

so

The cost of the car wash is $8

Find the cost of one gallon of gasoline

we know that

The slope of the linear equation is

m=$3.55 per gallon

therefore

The cost of one gallon of gasoline is $3.55

Part c) Write an inequality that represent the possible amounts of gasoline you can buy

we have

$3.55x+8 \leq 40$

Solve for x

$3.55x \leq 40-8$

$3.55x \leq 32$

$x \leq 9.01\ gal$

Part d) Use the graph to estimate the solution of the inequality in part c)

we have the system

y=40

y=3.55x+8

The solution of the system is the intersection point both graphs

Looking at the graph the intersection point is about (9,40)

That means ----> The maximum amount of gasoline you can buy with the budget is about 9 gallons

271+425 use rounding or compatible numbers to estimate the sum

Irina-Kira [14]

271 rounded is 300, and 425 rounded is 400, so you could estimate the sum by adding 300 and 400, which equals 700.
