1938

Step-by-step explanation:

For this, you will need to use order of operations. You would need to multiply 56 and 34 to get 1904 first, because multiplication comes before addition.

Remember to use PEMDAS.

34 + 56 x 34

56 x 34 = 1,904
(Because PEMDAS)

1,904 + 34 = 1,938

The circle graph represents a family’s monthly budget. If the total monthly budget is $6,500.00, how much more does the family spend on housing than food?

Answers

Answer:

Use the percentages to help you.

Ask yourself, what is 25% of $6,500.00?

Turn your percent into a decimal which is 0.25

then multiply $6,500 by 0.25

you should get 1625.

Find the amount of money spent on the food and find the difference of the two.

C. $390.00

Explanation:

Housing: 6,500/.25= $1,625
Food: 6,500/.19= $1,235

Subtraction:
$1,625 - $1,235= $390

The family spends $390.00 more dollars in housing than food.

What is Arithmetic Mean?

The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Given:

According to box plot the mean is

= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26

= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26

= 195 / 26

= 7.5

Hence, the mean is 7.5.

Also, the median = (7+8)/2 = 7.5

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.

a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.

Answers

Answer:

Equation: y=(-1/20)x+12.

Slope: -1/20

Y-intercept: (0, 12)

Step-by-step explanation:

Let x=the number of gallons of gas in Christopher's car.

If we start with 12 gallons, we have the equation: y=(-1/20)x+12.

This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

Round 6 6/13 to the nearest whole number.

Answers

6.

1/3 is not 1/2 or more than 1/2 so you have to round down.

Rounding to the nearest whole number involves writhing out the value of a number to the nearest integer value. Hence, the number would be written as 6

Converting the fractional value to decimal ; 6 61/3 = 6.461

Since the first digit after the decimal point is less than 5, we round to 0

Therefore, the number would be written as 6 (nearest whole number).

Answer:

b) 105*

c) 105*

Step-by-step explanation:

a) the car is facing west or left. If you imagine it spinning completely around to face east, it would be turning 180*. However it does not go that last 75* shown on the map. So 180 - 75 = 105

b) The angle diagonal to the 105* angle is also 105*. And since 3rd and 4th street are parallel so is the angle you are trying to find
