Answer:
So Cody increase his savings by 87.5%
Step-by-step explanation:
We are given Cody's original savings = $40
We are given his new savings total = $75
Now, in order to find out the percentage we have to first find out by how much did he increase his savings:
Increase in savings = $75 - $40 = $35
So now we have the increase in savings we can find out the percentage:
[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]
Now we plug in our values that we found:
[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]
So Cody increase his savings by 87.5%

Casey wants to buy a gym membership. One gym has a $70 joining fee and cost $35 per month. Another Jim has no joining fee and cost $70 per month. when would Casey pay the same amount to be a member of either gym? How much would he pay?
Answer:
same amount at 2 months. he'd pay 140.
Step-by-step explanation:
35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.
the second gym is also 140 for the two months because each month is $70. and 70+70=140

What is least amount of surface area possible on a rectangular prism with a volume of 64 cubic inches? What are the dimensions of this rectangular prism?
Answer: 64=s3
Step-by-step explanation: V=s3
64=s3
find the cubic root of each side
3√ 64=s4=s
so the side of the cube is 4 cu in.
The surface area of a cube is
SA=nA
where SA
is surface area, n
is the number of faces, and A
is the area of one face.
Te area of one face (A) is s2 so

A right triangle has legs measuring 5 feet and 12 feet. If the legs of the triangle were doubled, what would be the difference in the original and enlarged perimeters?
Answer:
[tex]30[/tex]
Step-by-step explanation:
1. Approach
First, use the Pythagorean theorem to solve for the hypotenuse of the given right triangle. Then find the perimeter by adding up the values of all the sides. The problem then has the lengths of the legs doubled. When the legs undergo a scaling factor, the hypotenuse and perimeter undergo the same scaling factor. Here, the legs are doubled, hence the hypotenuse and the perimeter are also doubled. Finally, subtract the new perimeter from the original perimeter.
2. Find the original hypotenuse
Remember the Pythagorean theorem states;
[tex]x^{2}+y^{2}=z^{2}[/tex]
Where (a) and (y) are the legs (or the sides adjacent to the right angle), and (z) is the hypotenuse or the side opposite to the right angle.
Substitute in the given value and solve,
[tex](5)^{2}+(12)^{2}=z^{2}\\\\25 + 144 = z^{2}\\\\169=z^{2}\\\\\sqrt{169}=z\\\\13=z[/tex]
3.Find the perimeter of the original triangle
To find the perimeter of a polygon, one must add up the lengths of all the sides.
[tex]5 + 12 + 13\\\\= 30[/tex]
4. Find the new perimeter
In a right triangle, when both legs undergo a scaling factor, the hypotenuse also has the same change, and the perimeter also undergoes the same change. In this case, the length of the legs is doubled, therefore, the hypotenuse and the perimeter are also doubled.
New hypotenuse; [tex]26[/tex]
New perimeter; [tex]60[/tex]
5. Find the difference
Now all that is left is to subtract the new perimeter from the original perimeter;
(New_perimeter) - (original_perimeter)
= [tex]60 - 30[/tex]
= [tex]30[/tex]

Answer:
Did you know that Aronson and Carnes-McNaughton's have the perspective on how they study
ancient things from the past.I agree that Aronson will agree with Carnes--McNaughton's statement because they both said the same thing but just in different words. For example in the book "If Stones Could Speak," it will tell what Aronson statement was about when it comes to archaeology and in "Profiles Of Archaeologist," it will tell you the same statement but just in different words. For example it states in the book "If Stones Could Speak," on page 56 "Marc Aronson believes that, “It is about putting aside what you think you know, what has been passed along, and being willing to trust what you yourself see and to test it rigorously.” From this quote the reader will now know what Aronson thinks when it comes to archaeology. In "Profiles Of Archaeologist." On paragraph 19 It states "Being an archaeologist means looking at the world around us in a different perspective. We live in the present as we study the past in order to learn what to do in the future---- on this planet and possibly other. We learn to be humanities while at the same time we practice as scientists. From this quote the reader can understand that both of these statements are similar but they are just reworded. In closing, This why I think that Aronson and Carnes will agree to what to what there statement was.
Step-by-step explanation:
Answer:
Part 1: At eight hours they both charge the same.
Part 2: Flush Plumbing charges the least
Step-by-step explanation:
Part 1:
Flush Plumbing Co Equation: 50 + 10 h (h = hours)
Fire-in-the-hole Plumbing: 90 + 5h (h = hours)
50 + 10h = 90 + 5h
Solve the Equation:
5h = 40
h = 8
Part 2:
Plug in 7:
Flush Plumbing: 50 + 10 x 7 = 50 + 70 = $120
Fire-in-the-hole Plumbing: 90 +5 x 7 = 90 +35 = $125
Flush plumbing chargers the least

(2t2 - 36t + 162). - (t-9)
Answer:
2t^2 - 37t + 171
Step-by-step explanation:
distrube the - to the (t-9) and then combine like terms
Answer:(2t2 + 27t) - 162 = 0
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 2t2+27t-162
The first term is, 2t2 its coefficient is 2 .
The middle term is, +27t its coefficient is 27 .
The last term, "the constant", is -162
Step-1 : Multiply the coefficient of the first term by the constant 2 • -162 = -324
Step-2 : Find two factors of -324 whose sum equals the coefficient of the middle term, which is 27 .
-324 + 1 = -323
-162 + 2 = -160
-108 + 3 = -105
-81 + 4 = -77
-54 + 6 = -48
-36 + 9 = -27
-27 + 12 = -15
-18 + 18 = 0
-12 + 27 = 15
-9 + 36 = 27 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 36
2t2 - 9t + 36t - 162
Step-4 : Add up the first 2 terms, pulling out like factors :
t • (2t-9)
Add up the last 2 terms, pulling out common factors :
18 • (2t-9)
Step-5 : Add up the four terms of step 4 :
(t+18) • (2t-9)
Which is the desired factorization
Equation at the end of step
2
:
(2t - 9) • (t + 18) = 0
STEP
3

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

At a car dealership, 72 trucks were sold in one month. If 60% of
the total vehicles sold were trucks, how many total vehicles were
sold that month?
A 12
B 132
C 120
D 160
Answer:
The total number of vehicles is: x = 120
Hence, option C is correct.
Step-by-step explanation:
Total trucks that were sold in one month = 72 trucks
Let 'x' be the total number of vehicles.
Given that 60% of the total vehicles sold were trucks.
Thus,
60% of x = 72
60/100 × x = 72
x = [72 × 100] / [60]
x = 120
Therefore, the total number of vehicles is: x = 120
Hence, option C is correct.
Answer:
C 120
