Answer: You have the following information given in the problem above:
- Lou filled the tank with gas that cost $3.80 per gallon.
- Lou's car had 5.9 gallons in the 13-gallon tank.
2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
3. Then, the result is:
$26.98

Find the value of: 2.52 =
Answer:
6.25
Step-by-step explanation:
Since 2.5 is squared, we should multiply it by itself once which will give us 6.25
Answer:
2.5^2 = 6.25
Step-by-step explanation:
2.5^2 is basically the same thing as 2.5*2.5, so you can do these either way if you like. You should get 6.25 as your result of the answer.
HELP THIS IS DUE IN ONE HOUR I NEED A GOOD ANSWER! Each sales associate at an electronics store has a choice of the two salary options shown below.
• $115 per week plus 9.5% commission on the associate’s total sales
• $450 per week with no commission
a. The average of the total sales amount for each associate last year was $125,000. Based on this average, which salary option would result in a higher salary?
b. What is the difference between the two salary options?
Answer:
A) The best option would be a fixed weekly salary of $ 450.
B) The difference between the two options is $ 106.64.
Step-by-step explanation:
A) To determine which option would result in a better salary, knowing that on the one hand you can have a fixed salary of $ 450 per week without commission, while on the other you can have a salary of $ 115 per week plus a commission of 9.5% on the total sales of Each associate, knowing that the average annual sales of each associate in the last year was $ 125,000 and that each year has 52 weeks, the following calculation must be made:
125,000 / 52 = Average sales per week
2,403.84 = Average sales per week
2,403.84 x 0.095 = Weekly commission
228.36 = Weekly commission
228.36 + 115 = Weekly salary
343.36 = Weekly salary
Therefore, the best option would be a fixed weekly salary of $ 450.
B) The difference between both options arises from the subtraction between each amount received by the worker, that is:
450 - 343.36 = X
106.64 = X
Therefore, the difference between the two options is $ 106.64.

Maggie runs 1/4 of a mile in 1.3 minutes. Olivia runs 2/3 of a mile in 2.9 minutes. Who runs faster? HOW MICH FASTER PER HOUR DOES THE PERSON RUN?
Answer:
Code: Olivia-2.40
Step-by-step explanation:
Given that:
Maggie runs 1/4 of a mile in 1.3 minutes
1/4 can also be written as 0.25
Speed = [tex]\frac{Distance}{Time}[/tex]
Speed = [tex]\frac{0.25}{1.3}[/tex]
Speed of Maggie = 0.19 miles per minute
Speed of Maggie per hour = 0.19*60 = 11.40 miles per hour
Olivia runs 2/3 of a mile in 2.9 minutes
Speed = [tex]\frac{\frac{2}{3}}{2.9}=\frac{2}{2.9*3}[/tex]
Speed = [tex]\frac{2}{8.7}[/tex]
Speed of Olivia = 0.23 miles per minute
Speed of Olivia per hour = 0.23*60 = 13.80 miles per hour
Therefore,
Olivia runs faster.
Difference = 13.80 - 11.40 = 2.40 miles
Hence,
Code: Olivia-2.40
Answer:
Olivia-2.25

Step-by-step explanation:
Solve for X!! I’ll give BRAINLIEST
Answer:
x = 75
Step-by-step explanation:
1. Find the inner angle (opposite from where x is), using the outer angle of 150.
Note: these two angles are supplementary, meaning that they add up to 180 degrees.
Since the outer angle is 150, the inner angle is 30 degrees because 150+30 = 180.
2. Find the other two angles to get x.
The red markings on the two sides of the triangle indicate that this is an isocoleses triangle. Isocoleses triangles have two congruent angles. This means that the remaining two angles will be the same.
With that in mind, recall what I said about the angles being supplementary. All angles in a triangle add up to 180. So, use the following equation and solve for x.
2x + 30 = 180 (Subtract 30 from both sides)
2x = 150 (divide by 2)
x = 75
3. x = 75
Answer:
X = 65 degrees
Step-by-step explanation:
180 - 150 = 30 the angle beside the 150 degrees
180 - 30 = 130 180 degrees is the sum of all three angles in a triangle
130/2 = 65 since both sides are equal the other 2 angles are the same
What is the difference between Susan’s and Jim’s lawn-care businesses in the amounts they charge for 10 hours of work?
Answer:
Let's assume that Susan's graph is linear. Then, we can do linear interpolation. Let y be the amount charged for 10 hours of work done:
(7-10)/(7-11) = (168-y)/(168-264)
y = $240
For Jim's Lawn care, let's find the constant slope using points (1,20) and (2,40):
m = (20 - 40)/(1-2) = 20
Then, since the y-intercept is zero, the linear equation is:
y = 20x
Substituting x = 10 hours,
y = 20(10) = $200
The difference between the two would then be:
Difference = $240 - $200 = $40

can u pls help me with this question
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', the equation becomes
y ∝ x
y = kx
where 'k' is called the constant of proportionality.
From the table, it is clear that 'y' varies directly with 'x'
Let us check the value of k for all the points
k = y/x
For the point (130, 9.10)
k = 9.10 / 130 = 0.07For the point (145, 10.15)
k = y/x = 10.15 / 145 = 0.07For the point (150, 10.50)
k = y/x = 10.50 / 150 = 0.07For the point (185, 12.95)
k = y/x = 12.95 / 185 = 0.07Thus, the value of proportionality constant is same.
i.e. k = 0.07
Determining the cost of 21 feet of the wire
And need 21 feet of the wire.21 feet = 252 inch
Using the equation
y = kx
where y represents the cost and x represents the length in inchesThus, the cost of 252-inch wire will be:
y = kx
substituting k = 0.07, and x = 252
y = 0.07 × 252
y = 17.64 Dollars
Thus, the cost of 21 feet wire will be: 17.64 Dollars
Determining the cost of 15 yards of the wire
Emily needs 15 yards of the wire.15 yards = 540 inches
Using the equation
y = kx
where y represents the cost and x represents the length in inchesThus, the cost of 15 yards of wire will be:
y = kx
substituting k = 0.07, and x = 540
y = 0.07 × 540
y = 37.8 Dollars
Thus, the cost of 15 yards of wire will be: 37.8 Dollars

The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 117 and standard deviation of 17 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure
Answer:
the percentage of adults have stage 2 high blood pressure is 0.0057
Step-by-step explanation:
The computation of the percentage of adults have stage 2 high blood pressure is shown below;
Given that
mean = 117
Standard deviation = 17
and, the sample is 160
Now based on the above information,
The percentage is
= (Sample - mean) ÷ (standard deviation)
= (160 - 117) ÷ (17)
= 2.529
p(z>2.53) = 0.0057
hence, the percentage of adults have stage 2 high blood pressure is 0.0057
