help me pls i need this ive been waiting for 5 hours
Step-by-step explanation:
15.2*15.2=231.04
5.98*5.98=35.76
35.76 = 15.47
231.04 100
100-15.5= 84.5%
let me know if I was right cause I'm pretty sure its the answer
I need to know that slope and y-intercept, I also need to know what y=_x+_
This is a inverse

The siding of a house is 2250 square feet. The siding needs two coats of paint. One quart costs $18 and covers 80 square feet. One gallon costs $29 and covers 320 square feet. What is the minimum cost of the paint needed to complete the job? How much paint is left over?
Answer:
Minimum cost needed = $221
Remaining quart paint = 7/8
Step-by-step explanation:
Let
x = number of 1 gallon paints
y = number of 1 quart paints
1 gallon covers 320 square feet
1 quart covers 80 square feet
Number of gallons paint needed = Total siding of the house / 320 square feet
= 2250 / 320
= 7.0312
Approximately to the nearest whole number
Number of gallons paint needed = 7 gallons
Total siding of the house covered by gallons = 7 gallons × 320 square feet
= 2,240 square feet
Siding of the house remaining = Total siding - Siding covered
= 2,250 - 2,240
= 10 square feet
1 quart covers 80 feet
Therefore, 1 quart will cover the remaining 10 square feet
A. The minimum cost of the paint needed to complete the job
Total cost = (Price of gallons × Quantity of gallons needed) + (price of quart × Quantity of quart needed)
= (29 × 7) + (18 × 1)
= 203 + 18
= $221
Minimum cost needed = $221
B. How much paint is left over
Recall
1 quart covers 80 square feet
And remaining siding to be covered = 10 square feet
That is,
10/80 = 1/8 of a quart paint used
Remaining quart paint = 1 - 1/8
= 7/8 quart paint

no

Ray buys bottles of water at $2 each and a large pizza at $13. The total cost was $21. what equation can be used to find the number of water bottles purchased A 13+21x=2 b 13x+2=21 c 21+2x=13 or d 2x+13=21
Answer:
13 + 2x = 21 where x is the number of bottles of water
Step-by-step explanation:
pizza plus water = 21
13 + water = 21
Each water is 2 dollars
13 + 2x = 21 where x is the number of bottles of water
I NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I WILL GIVE BRAINLIST WHOEVER COMES FIRST Evaluate the expression if x = 9 and y = 2. 5x + y
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
Find the inverse of the function f(x) = x3 + 5
Answer:
[tex]{f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]Step-by-step explanation:
[tex]f(x) = {x}^{3} + 5[/tex]
To find the inverse of f (x) , equate f(x) to y
That's
y = f(x)
[tex]y = {x}^{3} + 5[/tex]
Next interchange the terms
That's x becomes y and y becomes x
[tex]x = {y}^{3} + 5[/tex]
Next solve for y
Send 5 to the other side of the equation
[tex] {y}^{3} = x - 5[/tex]
Find the cube root of both sides to make y stand alone
That's
[tex] \sqrt[3]{ {y}^{3} } = \sqrt[3]{x - 5} [/tex]
[tex]y = \sqrt[3]{x - 5} [/tex]
We have the final answer as
[tex] {f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]
Hope this helps you

What is the sum of the following equatiioin? 10x+20y+5x=?
Answer:
15x + 20y
Step-by-step explanation:
First, we need to combine like terms,
10x + 20y + 5x
15x + 20y
Since x and y are different variables, we cannot combine them, meaning that the answer is,
15x + 20y

There is a math student in distress over Algebra 2. Pi-Guy quickly travels to go tutor the student. Here is Pi-Guy’s movement to travel to the student: he flips downward, flies 7 units to the right, and then down 8 units. Write the equation f(x) to show the movements that Pi-Guy makes from his original location (the parent function from Part 1). You do not need the specific type of function, just write in terms of f(x).
Answer:
See below explanation
Step-by-step explanation:
So you just have to move the heroine around the map. Draw out a map with a village and the hero-guy will go save the college student.
Equational path (you have to make sure f(x) is in the pathological way because that is part of the instructions for this problem) : g(y) = a^8 + 7(f(x)
This shows that the guy went 8 miles and then 7 in the function.
To show the flip that the guy does, just turn the equation around: f(x)*7 +a^8 = g(y)
Answer:
f(x)*7 +a^8 = g(y)

what is greater than 3:5
Answer:
They have a common numerator, that is 3. Therefore we can directly conclude that fraction with smaller denominator is greater of the two. Thus 3/5 is greater than 3/6. One way to compare the two fractions would be to both have the same denominator, so that numerators will be easily compared
