The Ortiz family will travel from Indianapolis to Denver this summer. The driving distance between the two cities is 1,058 miles. They need to find out about how much the gas will cost round trip. Their car gets about 20 miles per gallon. A. Write and solve an algrebraic equation to find out how many gallons of gas they will use. Explain your steps. B. Write and solve an algebraic equation to find out how many miles they will travel.

We get the following outcomes

(I) Relation between distance,mileage, and Amount of fuel spent is   D=MN

(II) Amount of gas spent to travel 1058 miles = 52.29 gallons

It is given that

Distance D between two cities = 1058 miles

Mileage M of the car = 20 miles per gallon

as we know that

distance traveled D = mileage M* Number of gallons N

D=MN

### what is the mileage?

Mileage is the number of miles traveled or covered.

So, the amount of gas spent to travel 1058 miles:

D/M = 1058/20 =52.29 gallons.

Hence,(I) relation between distance,mileage, and amount of fuel spent is D=MN.

(II) Amount of gas spent to travel 1058 miles = 52.29 gallons

A. Write and solve an algrebraic equation to find out how many gallons of gas they will use. Explain your steps.

let x = gallons of gas they will use
y = distance traveled

x = y/20
x = 1058/20 = 52.9 gallons of gas

B. Write and solve an algebraic equation to find out how many miles they will travel.

let x = distance traveled
y = gallons of gas used

x = 20y
x = 20(52.9)
x = 1058 miles

Hope this helps. Have a nice day.

A consumer advocate wants to collect a sample of jelly jars and measure the actual weight of the product in the container. He needs to collect enough data to construct a confidence interval with a margin of error of no more than 3 grams with 95​% confidence. The standard deviation of these jars is usually 3 grams. Estimate the minimum sample size required.

n=3.8416≅4

So Minimum Sample Size is 4

Step-by-step explanation:

In order to find the minimum sample size, the formula we use will be:

Where:

n is sample size

Z is the distribution

S is the standard deviation

E is the  Margin of error

S=3 ,E=3

For Z:

Alpha=1-0.95=0.05

Alpha/2=0.025=2.5%

From Cumulative Standard Distribution Table:

Z at Alpha/2 = 1.960

n=3.8416≅4

So Minimum Sample Size is 4

True or False
100% of any number must greater than or
equal to 100

False

The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle?

3 units ×16 units

Step-by-step explanation:

Please see the attached picture for full solution.

Length = x+13=6+13=19units

Step-by-step explanation:

P = 2(l +w)

Let width be x

Length = x + 13

P = 38

38 = 2(x + 13 + x)

38 = 2(2x + 13)

38 = 2x + 26

2x = 38 - 26

2x = 12

x = 12/2

x = 6unit

Width = 6units

Length = x + 13 = 6+13 = 19units
