If one gallon of paint covers 270 square feet, how many gallons of paint will be needed to cover the shed, not including the roof? If a gallon of paint costs $25, about how much will it cost to paint the walls of the shed?
Answer:
$58.5
Step-by-step explanation:
the surface area of the shed =
[2×(11+15)×11] +[2×½×15×4]
= 572 +60
= 632 ft²
the total costs = 632/270 × $25 = $58.5

What is linear equations in two variables?When written as ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not zero, an equation is said to be a linear equation in two variables.
For this kind of equation, the solution is a pair of values, one for x and one for y, which also make the two sides equal.
Given Equations 12x + 6y = 12...….(1)
y = x + 15
y - x = 15...….(2)
divide eq. (1) by 6
(12x + 6y)/6 = 12/6
2x + y = 2
subtract from eq. (2)
y - x - (2x + y) = 15 - 2
-3x = 13
x = -13/3 = -4.334
substitute value of x in eq. (2)
y - (-4.334) = 15
y = 15 - 4.334
y = 10.667
Hence the solution of equations gives x = -4.334 and y = 10.667.

A study was conducted to examine whether the proportion of females was the same for five groups (Groups A, B, C, D, and E). How many degrees of freedom would the ????2 test statistic have when testing the hypothesis that the proportions in each group are all equal?
a. 1.
b. 0.20.
c. 5.
d. 4.
Answer:
d. 4
Step-by-step explanation:
The degree of freedom is the amount of independent data set used to calculate an estimate. The degree of freedom is quite different from the sample size (n). It is calculated by subtracting one(1) from the total value of the data set (sample size (n)).
From the information given:
The sample size is the number of people in the same group
sample size n = 5
degree of freedom = n - 1
= 5 - 1

title: 300%payday: 650%check cashing: 214%Step-by-step explanation:
The formula for simple interest is ...
I = Prt
where P is the principal amount loaned, r is the annual rate, and t is the time in years. Solving for interest rate, we get ...
r = I/(Pt)
We assume 12 months or 52 weeks in a year.
__
Car title loan
r = 125/(500×1/12) = 3 × 100% = 300%
The APR is 300%.
__
Payday loan
r = 125/(500×2/52) = 6.5 × 100% = 650%
The APR is 650%.
__
Check cashing
r = 19.66/(478.41×1/52) ≈ 2.1369 × 100% ≈ 214%
The APR is about 214%.
What is the inverse of the function f(x) = 169x2 when x ≥ 0?
A- f−1(x) = 13‾‾
B- f−1(x) = √13
C- f−1(x) = 13x
D- f−1(x) = 113
Answer:
[tex]f^{-1}(x) = \frac{\sqrt{x}}{13}[/tex]
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse, we exchange the y and the x values, and then isolate y.
Function:
[tex]f(x) = 169x^2[/tex]
That is:
[tex]y = 169x^2[/tex]
Exchanging x and y:
[tex]x = 169y^2[/tex]
Isolating y:
[tex]y^2 = \frac{x}{169}[/tex]
[tex]y = \sqrt{\frac{x}{169}}[/tex]
[tex]y = \frac{\sqrt{x}}{13}[/tex]
[tex]f^{-1}(x) = \frac{\sqrt{x}}{13}[/tex]
Gabriela makes a profit of $0.80 for every cup of coffee that she sells at her coffee shop. She wanted to make a profit of at least $75 today on coffee. If she sold 90 cups today, which statement is correct? She met her goal, because she made less than $75 on coffee today. She met her goal, because she made more than $75 on coffee today. She missed her goal, because she made less than $75 on coffee today. She missed her goal, because she made more than $75 on coffee today.What is the value of the expression below?
(9.5 minus 3 times 1 and one-half) divided by 0.5
0.5
5
10
19.5
Answer:
She missed her goal, because she made less than $75 on coffee today.
10
Step-by-step explanation:
Target profit = $75
Profit per cup = $0.80
Number of cups sold = 90
Profit made today = Profit per cup * Number of cups sold
= $0.80 * 90
= $72
She missed her goal, because she made less than $75 on coffee today.
2. (9.5 minus 3 times 1 and one-half) divided by 0.5
(9.5 - 3 * 1 1/2) ÷ 0.5
= 9.5 - 3 * 3/2 ÷ 0.5
= 9.5 - 9/2 ÷ 0.5
= (9.5 - 4.5) ÷ 0.5
= 5 ÷ 0.5
= 10

Emma wants to buy a new cell phone. She commits to saving 10% of the cost
each month. Let p be the percent she has saved after m months.
Answer:
p(m) = 0.1(m)
Step-by-step explanation:
Given that :
Percentage of cost saved per month = 10%
The percentage, p of cost saved after m months will be ;
Percentage of cost saved after m, months will be ; p(m) = Percentage of cost saved per month * number of months
p(m) = 10% * m

Write an exponential function in the form y and (2,396) ab" that goes through points (0,11)
Answer:
[tex]y =11(6)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,11)[/tex]
[tex](x_2,y_2) = (2,396)[/tex]
Required
The exponential function
This is represented as:
[tex]y = ab^x[/tex]
In [tex](x_1,y_1) = (0,11)[/tex], we have:
[tex]11 = ab^0[/tex]
[tex]11 = a*1[/tex]
[tex]a = 11[/tex]
So, we have:
[tex]y = ab^x[/tex]
[tex]y = 11b^x[/tex]
In [tex](x_2,y_2) = (2,396)[/tex], we have:
[tex]396 = 11 * b^2[/tex]
Divide both sides by 11
[tex]36 = b^2[/tex]
Taks square roots
[tex]6 = b\\\\b=6[/tex]
So, we have:
[tex]y = 11b^x[/tex]
[tex]y =11(6)^x[/tex]
For this line 3x−4y−12=0, which statement is true? 1- The x-intercept is 4, and the y-intercept is 3. 2-The x-intercept is 4, and the y-intercept is -3 3-The x-intercept is 3, and the y-intercept is -4. 4-The x-intercept is 3, and the y-intercept is 4.
9514 1404 393
Answer:
2. The x-intercept is 4, and the y-intercept is -3
Step-by-step explanation:
The given equation is in general form. I find it easier to see the intercepts when the equation is written in standard form:
3x -4y = 12
Setting y=0 and solving for x, we have the x-intercept:
3x = 12 ⇒ x = 12/3 = 4
Setting x=0 and solving for y, we have the y-intercept:
-4y = 12 ⇒ y = 12/-4 = -3
The x-intercept is 4; the y-intercept is -3.

Find the dicontinuities of the function.
f(x) =
x2 + 12x + 27
x2 + 4x + 3
.
There is a removable discontinuity at
(
,
).
Answer:
Step-by-step explanation:
I'm assuming you meant to type in
[tex]f(x)=\frac{x^2+12x+27}{x^2+4x+3}[/tex] because you can only have removable discontinuities where there is a rational (fraction) function. Begin by factoring both the numerator and denominator to
[tex]f(x)=\frac{(x+3)(x+9)}{(x+1)(x+3)}[/tex] and cancelling out like terms would have us eliminating the (x + 3). That is where there is a removable discontinuity. It leaves a hole. The other discontinuity, (x + 1) doesn't cancel out so it is a non-removable discontuinity, which is a vertical asymptote.
The removable discontinuity is at -3. There is no y value at x = -3 (remember there's only a hole here), because -3 causes the denominator to go to 0 and we all know that having a 0 in the denominator of a fraction is a big no-no!!!

Find the amount of interest for a 19-year investment of $4500 at a simple annual rate
of 2.73%
Answer:
A = $7,554.84
A = P + I where
P (principal) = $4,500.00
I (interest) = $3,054.84First, convert R as a percent to r as a decimal
r = R/100
r = 2.73/100
r = 0.0273 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,500.00(1 + 0.0273/12)(12)(19)
A = 4,500.00(1 + 0.002275)(228)
A = $7,554.84
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $4,500.00 at a rate of 2.73% per year compounded 12 times per year over 19 years is $7,554.84.
