Roberto and Maria Santanos spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and
dryer would cost them a total of $774. How many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer?
HELP PLEASE!
Answer:
72 weeks
Step-by-step explanation:
If 1 week =$10.75 then $774 will be equal to $774×1 week=774 then divide by $10.75=72 weeks
It will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.
We have - Roberto and Maria Santana's who spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and dryer would cost them a total of $774.
We have to determine in how many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer.
If you are saving $5 every day, then in how many days you will save %100?You will save $100 in = [tex]\frac{100}{5}[/tex] = 20 days.
According to question, we have -
Cost of a Laundromat = $10.75/week
Total cost of a new washer and dryer = $774.
The number of weeks it will take for the laundromat cost to equal the cost of a new washer and dryer will be -
n(W) = [tex]\frac{774}{10.75}[/tex] = 72 weeks
Hence, it will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.

1. f(x) = x2 + x and g(x) = 2x + 1
a. Evaluate f(g(3))
b. Evaluate g(f(3))
Answer:
f(g(3)) = 56
g(f(3)) = 25
Step-by-step explanation:
fog = f(2x+1)
f(2x+1) = (2x+1)^2 + 2x+1
(2x+1)^2 + 2x+1 = 4x^2+6x+2
f(g(x)) = 4x^2+6x+2
f(g(3)) = 4(3)^2+6(3)+2
f(g(3)) = 56
gof = g(x^2+x)
g(x^2+x) = 2(x^2+x)+1
2(x^2+x)+1 = 2x^2 + 2x + 1
g(f(x)) = 2x^2 + 2x + 1
g(f(3)) = 2(3)^2 + 2(3) + 1
g(f(3)) = 25
I NEED HELP WITH OPPERATIONS WITH COMPLEX NUMBERS
(PLEASE HELP)
Answer:
see below
Step-by-step explanation:
z1 = sqrt(3) -i
z2 = -i
z1+z2 = sqrt(3) -i + -i = sqrt(3) -2i
z1-z2 = sqrt(3) -i - -i = sqrt(3) +-i +i = sqrt(3)
z1*z2 = sqrt(3) -i * -i = sqrt(3)*-i -i*-i = -sqrt(3)i + i^2 = -sqrt(3)i -1
z1/z2 = sqrt(3) -i / -i = sqrt(3)/-i - i/-i = sqrt(3) *i/-i*i +1 = sqrt(3)i/-i^2 +1
= sqrt(3) i +1

In a New York coupon experiment, the experiment was conducted to test the effects of the face value of coupons on the likelihood of coupon redemption. Subjects were randomly assigned to 2 treatment groups. One group was offered 15-cent coupons and the other 50-cent coupons for four products. During the interviews, the respondents answered questions about which brands they used and how likely they were to cash coupons of the given face value the next time they shopped. In the preceding experiment, the dependent variable that was ________.

the length of a rectangle is 24 feet more than the width. The perimeter of the rectangle is 88 feet. What is the length and width of this rectangle?
Answer:
W = 10 ft
Step-by-step explanation:
Represent the length by L and the width by W. Then L = W + 24.
The perimeter is P = 2W + 2L, or 88 ft. Thus, after substituting L = W + 24,
88 ft = 2W + 2(W + 24), or
88 = 2W + 2W + 48, or, after reduction,
44 = 2W + 24, or
2W = 20, and so W = 10 ft
The length of the rectangle is 34 feet.
The given parameters;
perimeter of the rectangle, P = 88 feet.let the width of the rectangle = wthen, the length of the rectangle, L = 24 + wThe length of the rectangle is calculated as follows;
P = 2(L+ w)
P = 2(24 + w + w)
P = 2(24 + 2w)
88 = 48 + 4w
subtract 48 from both sides of the equation;
88 - 48 = 4w
40 = 4w
w = 10
Now, solve for the length;
L = 24 + w
L = 24 + 10
L = 34 feet
Thus, the length of the rectangle is 34 feet.

4x+1y=12 solve please need help
Answer:
-0.25y
Step-by-step explanation:
Simplifying
4x + 1y = 12
Solving
4x + 1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
4x + 1y + -1y = 12 + -1y
Combine like terms: 1y + -1y = 0
4x + 0 = 12 + -1y
4x = 12 + -1y
Divide each side by '4'.
x = 3 + -0.25y
Simplifying
x = 3 + -0.25y
Answer:
x = 3 + -0.25y
Step-by-step explanation: Simplifying:4x + 1y = 12Solving:4x + 1y = 12Solving for variable 'x'.:Move all terms containing x to the left, all other terms to the right.Add '-1y' to each side of the equation.4x + 1y + -1y = 12 + -1yCombine like terms: 1y + -1y = 04x + 0 = 12 + -1y4x = 12 + -1yDivide each side by '4'.x = 3 + -0.25ySimplifyingx = 3 + -0.25yassume f(x)=-2x+8 and g(x)=3x. what is the value of (g o f)(3)
Answer:
6
Step-by-step explanation:
(g o f)(3) = g(f(3))
We can find f(3) using its formula with x=3:
f(3) = -2·3 +8 = -6 +8 = 2
Now, we can find g(2) using its formula with x=2:
g(2) = 3·2 = 6
So, the composition value is ...
(g o f)(3) = 6
