Answer:
Question 7: Company A has a lower rate
Question 8: Caiden's vehicle gets more miles per gallon
Step-by-step explanation:
Question 7:
According to the table for Company B's rates, if you divide the total cost by the square footage in each row, you would get $2.75/ft² each time. Therefore, Company A would charge the Smiths a lower cost per square foot.
$2.25/ft² < $2.75/ft²
Company A < Company B
Question 8:
Using the given equation, we already know that Caiden's vehicle has a gas mileage of 16.2 miles/gallon The graph for Ethan's gas mileage can be figured out using slope. Taking the points (0, 0) and (2, 30) on the line, we can figure out the line's slope.
slope = rise/run,
where "rise" is how much you add or subtract to get from the first y-value to the second, and "run" is how much you add or subtract to get from the first x-value to the second.
slope = rise/run
slope = 30/2
slope = 15/1
The slope of the line is 15, so that means the line's equation is y = 15x. Therefore, Ethan's gas mileage is 15 miles/gallon.
16.2 mpg > 15 mpg
Caiden > Ethan

Jen deposited $750 in her savings account. The account earns 2% simple interest per year. She has the money in her account for 24 months. How much money did she earn in simple interest?
Answers
Answer: $30
Step-by-step explanation:
She has the money in her account for 24 months which is 2 years.
Simple interest is formula is:
A = P (1 + rate * no. of periods)
= 750 * ( 1 + 2% * 2)
= $780
She started with $750 and now has $780.
Earnings in simple interest :
= 780 - 750
= $30

5(-1x+5)=10 pls help
Answers
Answer:
-5x+5=10
-5x=10-5
-5x=5
x=-5/5
x=-1
Step by step
5 ( –1x + 5) = 10
(1) Distribute
= – 5x + 25 = 10
(2) Subtract 25 from both sides of the equation
= –5x + 25 -25 = 10 – 25
(3) Simplify
= –5x = – 15
(4) Divide both sides of the equation by the same factor
= –5x/–5 = –15/ –5
(5) Divide the number
= x = –15/–5

Step-by-step explanation:
Using Pythagoras' Theorem, we have
x² + 10² = (12√3)²
Therefore x² = (12√3)² - 10²
= (144)(3) - (100) = 332.
=> x = √332 = 2√83. (B)

Mark wants to continue using whole liters of paint and thinks he can create a mixture of green paint the is 38 liters. Evaluate Mark's thinking using mathematical reasoning.
The ratio from blue to yellow paint is 2:3
I need helpppppp ASAP
Answers
Answer: It's not possible to create 38 liters of green paint with whole liters of blue and yellow paint.
======================================================
Explanation:
The ratio of blue to yellow is 2:3. We have 2 parts blue and 3 parts yellow.
Multiply both parts by x to get 2x:3x
We have 2x parts of blue paint, and 3x parts of yellow paint.
x is some positive whole number.
In total, we have 2x+3x = 5x liters of paint. Set this equal to 38 and solve for x to get
5x = 38
x = 38/5
x = 7.6
We don't get a whole number, which contradicts how we set up x earlier. This must mean that Mark must use a fractional liters, instead of whole liters.
-------------------------
Here's another way to look at it:
Lets say he uses 2 liters of blue and 3 liters of yellow. This mixes to 2+3 = 5 liters of green.
Now let's say he uses 4 liters of blue and 6 of yellow. I multiplied both parts by 2. This mixes to 4+6 = 10 liters of green.
We continue this process to get the following
6 liters of blue + 9 liters of yellow = 15 liters of green8 liters of blue + 12 liters of yellow = 20 liters of green10 liters of blue + 15 liters of yellow = 25 liters of green12 liters of blue + 18 liters of yellow = 30 liters of green14 liters of blue + 21 liters of yellow = 35 liters of green16 liters of blue + 24 liters of yellow = 40 liters of greenAs you can see, we don't land on 38 liters of green. We can get to 35 liters or 40 liters, but not 38. Each of the amounts of green are a multiple of 5.
This is confirmation that Mark will have to use some fractional amount of liters of blue and yellow paint.
Students planted 2(3x + 4y) amount of trees on Saturday and then 3(x + 8) amount of trees on Sunday. What is the total amount of trees that the students planted? *
Answers
Answer:
(9x + 8y + 24) trees
Step-by-step explanation:
The total amount of trees the students planted is calculated as:
Amount of trees planted on Saturday + Amount of trees planted on Sunday
= 2(3x + 4y) + 3(x + 8)
= 6x + 8y + 3x + 24
= 6x + 3x + 8y + 24
= 9x + 8y + 24
Hence, the total amount of trees the students planted was (9x + 8y + 24) trees

the first option is the answer, r = √6
Step-by-step explanation:
[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]
hypotenuse = q = √12
adjacent = p = √6
opposite = r
substitute the values into the hypotenuse formula

[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]

Answer:
C. 5.8
Step-by-step explanation:
We use the Pythagoras theorem here. which is a²+b²=c².
a and b are the replacements for the 5miles and 3miles here.
They are a and b because a and b are always on the right angle side.
The longest side of this triangle is called a hypotenuse which is the c in this case.
the other sides (a and b) are called the adjacent and the opposite.
it doesn't matter if you use adjacent or opposite for a and b in this case.
the only important thing is the hypotenuse here.
So it's a²+b²=c², which is 5²+3²=c².
5² is 25 and 3² is 9, so we add them and we get 34.
so c²=34, we don't want the square on c so we send it to 34 which becomes √34.
√34 gives us 5.8 miles which is up to just only one decimal place.
You might need to use calculators for square roots because they take long to calculate.
