sorry :(
Hopefully someone fills in the rest of the answers!!!
Answer:
Question 1:
8/12 = 4/6 = 3/x
0.6 = 0.6 = 3/x
It is a similar triangle, therefore 3/x = 0.6
x = 5 because 3/5 = 0.6
Question 2
You did that correct :)
Question 3:
"Check all that apply"
B
D
Question 4
You got question 4 wrong since similar triangles have similar ratio.
8/10 = 8/10 = 10/14
0.8 = 0.8 = 0.7
Correct answer for question 4 is B("No they are not similar because the ratios are not equal")
Question 5
The Quadrilaterals are similar. Therefore:
22.4/14 = 12.8/8 = 12/7.5 = 26/x
1.6 = 1.6 = 1.6 = 26/x
Meaning 26/x = 1.6
x = 16.25
Because 26/16.25 = 1.6

27x9^3x can be written in the form 3^k where K is an expression in terms of x. Find k
Answers
Answer:
k = 3 + 6x
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Given
27 × [tex]9^{3x}[/tex]
= 3³ × [tex](3^{2}) ^{3x}[/tex]
= 3³ × [tex]3^{6x}[/tex]
= [tex]3^{3+6x}[/tex]
= [tex]3^{k}[/tex] → with k = 3 + 6x

Question in picture solve
Answers
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
Check:
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
A rectangular swimming pool has a volume of 1750 ft.³ water is being added to the pool at a rate of about 20 ft.³ per minute. use an equation in point slope form to determine about how long will it take to fill the pool completely if there were already 1125 gallons of water in the pool use the fact that one cubic foot of space holds about 7.5 gallons of water round the answer to the nearest integer if necessary
Answers
Answer:
You have a rectangular pool 15 X 30 X 5 feet
The floor of the pool is 15X30 = 450 ft2
Two sides are 5X15 = 2(75) = 150 ft2
Two sides are 5X30 = 2(150) = 300 ft2
Total area to be painted: 900 ft2
(900 ft2)/(250 ft2/gal) = 3.6 gallons
Since we can't purchase .6 gallons we
must purchase 4 gallons of paint
The volume of the pool is 15X30X5 = 2250 ft3
1 ft3 = 7.48 gallons
2250(7.48) = 16,830 gallons of water

-6a +3 =-3(2a-1) question number 2
Answers
Answer:
D. identity
Step-by-step explanation:
- 6a + 3 = - 3(2a - 1)
First, distribute -3 within the parenthesis.
- 6a + 3 = - 6a + 3
Subtract 3 from both sides of the equation
- 6a = - 6a
Divide - 6 on both sides of the equation
a = a
We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity
For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.
I hope that this helps! :)

There are 4 quarts in a gallon.
She wants to convert 6 quarts to a gallon.
To find:
Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.
Solution:
We have,
[tex]4\text{ quarts}=1\text{ gallon}[/tex]
[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]
[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]
Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.
