Pablo's family began their trip with a full tank of gas in their car. They drove 384.1 miles and
stopped to fill their tank back up with gas. It took 14.2 gallons of gas to fill up their tank.
About how many miles per gallon of gasoline did they average on their trip?
Work Shown:
(384.1 miles)/(14.2 gallons) = (384.1)/(14.2) mpg = 27.049 mpg approximately
mpg = miles per gallon
Answer:
27.05 miles per gallon
Step-by-step explanation:
384.1 miles = 14.2 gallons
x = 1 gallon
14.2x = 384.1
x = 384.1/14.2
= 27.0492958
≈ 27.05 miles per gallon

The image point of A after a translation right 4 units and up 4 units is the point B(-5, -1). Determine the coordinates of the pre-image point A.
Answer:
(-9, -5)
Step-by-step explanation:
You have to imagine where it came from so the only way to find that is by reversing the translation. Instead of adding 4, we need to subtract 4 left and down. Once you did the inverse you receive your answer.

Alex wrote the expanded form for the number 165.038 as “100 + 60 + 5 + 30 + 8.” Was he correct? If not, give the correct expanded form. P.S I really need the answer asap!
Answer:
no he is not correct.
the correct expanded form: 100+60+5+0.0+0.30+0.008
Step-by-step explanation:
Hope this helps also i learned about this r u in 5th grade
Alex's expanded form for the number 165.038 is not correct. The correct expanded form for the number 165.038 is 100 + 60 + 5 + 0.03 + 0.008.
The number 165.038 can be broken down into its individual place values:
Hundreds: 100
Tens: 60 (6 tens)
Ones: 5
Tenths: 0.03 (3 hundredths)
Hundredths: 0.008 (8 thousandths)
So, the correct expanded form for the number 165.038 is:
100 + 60 + 5 + 0.03 + 0.008
Hence, Alex's expanded form for the number 165.038 is incorrect. The correct expanded form is: 100 + 60 + 5 + 0.03 + 0.008.

One example of a mathematical model is an equation that describes the relationship between two quantities.
a. True
b. False
Answer:
True
Step-by-step explanation:
Linear equations are often used to model the relationship between the dependent variable that is affected by changes in the independent variable.
For instance, the linear function: f(x) = 2x + 3, where f(x) is the output (dependent variable) depends on the value of the input, x (independent variable).
Therefore, the correct answer is True.

The perimeter of the rectangle below is 65 inches.
a. What is the value of x?
b. What are the dimensions of the rectangle?
Answer:
A :-) Given -
perimeter = 65 inches
Side ‘a’ = 2x
Side ‘b’ = 3 1 by 4x + 1
Solution -
Perimeter = 65
= a + b = 65
= 2x + 3 1 by 4x + 1 = 65
( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4
= 13 by 4 )
= 2x + 13 by 4x + 1 = 65
= 2x + 13 by 4x = 65 - 1
= 2x + 13 by 4x = 64
= 15 by 4 x = 64
= x = 64 x 4 by 15
= x = 256 by 15
= x = 17.06

Emma has just started a new sales job. She makes $20 an hour. On top of her hourly wages, she’ll be paid a commission of 15% on all sales she makes. Use this information to answer the following questions.
Part A
Question
Which equation in the form y = mx + cs models Emma’s situation?
y = 20x + 0.15
y = 20x + 15
y = 20x + 0.15s
y = 20x + 15s
Answer:
y = 20x + 0.15s
Step-by-step explanation:
Shew makes $20 par hour, so for x hours, she makes 20x.
She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.
The total she makes is 20x + 0.15s
Answer: y = 20x + 0.15s
The equation in the form y = mx + cs models Emma’s situation is
y = 20x + 0.15s
Shew makes $20 par hour, so for x hours, she makes 20x.
What is the slope-intercept form of the line?
The slope-intercept of the line y= mx+c
Where y co-ordinate
x- x co-ordinate
m=slope of the given line
C-y intercept.
She makes 15% commission on the sales, s. 15% = 0.15,
So for the sales, she makes
15% * s = 0.15s.
The total she makes is 20x + 0.15s
y = 20x + 0.15s

In how many ways can a committee
of 5 men and 3 women be selected
from 9 men and 7 women ?
Answer：
use the same method
Step-by-step explanation:
Men=5
Women=3
Available Strength:
Men=7
Women=6
Objective:Finding no of such committees where particular 2 women are never together.
So initially ,Total possible number of commitee=7c5×6c3=420.
Now we need to find total committes where two particular women say(Sita and Gita ) are never together.
Approach—->
As the commitee requires 5 men and 3 women.
Let us first find number of committees where Sita and Gita are always together.
Hence we reserve 2 women seats for them.
Now we need one women out of remaining 4 women.
So possible number of such commitees 7c5×4c1.
=84.
Hence number of committees where Sita and Gita are never together
=420–84
=336.
