On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is

baherus [9]

Answer:

$I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

$\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}$

$\frac{I}{F}=\frac{6}{16}$

Now, let us solve for $I$ .

$I=\frac{6}{16}\cdot F$

$I=\frac{3}{8}\cdot F$

Now, let us solve our equation for F.

$I\cdot\frac{8}{3}=\frac{8}{3}\cdot\frac{3}{8}\cdot F$

$\frac{8}{3}\cdot I= F$

$F = \frac{8}{3}\cdot I$

Therefore, our required equations would be $I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

A box contains 12 red marbles,8 blue marbles, and 4 yellow marbles. Three marbles are drawn at random with replacement (means I

Liula [17]

Answer: 1/8

Step-by-step explanation:

Number of red marbles = 12

Number of blue marbles = 8

Number of yellow marbles = 4

Total number of marbles = 24

Probability of getting red = 12/24 = 1/2

The probability of getting three reds with replacement will be:

= 1/2 × 1/2 × 1/2

= 1/8

Sharon earns $25 per item she sales plus a base salary of $100 per week. Write and solve an inequality to find how many items sh

artcher [175]

$25 per item sold + $100 per week = 700 total goal in 1 week

X is our items sold variable. We only use 100 since our goal is for only one week.
25x + 100 = 700

Subtract 100 from each side.
25x = 600

Divide by 25.
x = 24

Olegator [25]

Answer:

4g - 1

Step-by-step explanation:

4 and -5 are numbers

While, -6g and 10g are variables.

Add numbers and variable separately.

4 + -6g + 10g + -5

= 4 - 5 + 10g - 6g

= - 1 + 4g

= 4g - 1
