Answer:
raise = $0.76
new wage = $10.26 per hour
Step-by-step explanation:
8% in decimal form = 8/100 = 0.08
To find 8% of 9.50: 0.08 x 9.50 = 0.76
Therefore, the housekeeper's raise = $0.76
To calculate the amount she now earns after the raise, add the 8% rise to the initial value:
0.76 + 9.50 = $10.26
Answer:
y =-5x-17
Step-by-step explanation:
Slode-intercept is
y = mx + c
The first step is to find the slope, that is the m
To do that, use this formula
Y2 - y1
------------
X2- x1
And u will get - 5
Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs
So let's say I chose (-4, 3)
So x = - 4, y = 3
y=mx +c
3= - 5(-4) +c
C = - 17
Therefore your end product will be
y = - 5x - 17
The number of books sold is 473.
<u>Step-by-step explanation:</u>
- The original cost of each book = $0.64
- The selling price of each book = $0.75
The difference between the original price and selling price of the book gives the profit per book.
The profit of one book = Selling price - Original price
Let,
- The total number of books be 'x'.
- The number of books sold be 'y'.
- The unsold books is 100.
- The total profit is -12 because it was gone to a loss of $12.
Therefore, the equation is formed as
total Profit = 0.75y - 0.64x
⇒ 0.75y - 0.64x = -12 --------(1)
Total books = sold books + unsold books
x = y + 100
⇒ x-y = 100 -------(2)
Substitute x= 100+y in the eq(1),
0.75y - 0.64(100+y) = -12
0.75y - 64 -0.64y = -12
0.11y = -12 +64
y = 52 / 0.11
y = 472.7
y ≅ 473
The number of book sold is 473 books.
The total number of books is (100+473) = 573 books.
a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
in this case, 10 video games cost $145
the question's basically asking what you have to multiply 10 by to get 145
y= 145; x=10
k= y/x = 145/10=14.5
the constant of proportionality is 14.5
Answer:
S.A. = 981.7 ft^2
Step-by-step explanation:
radius = 25 ft
S.A. = 1/2πr2
S.A. = 1/2π(25)^2
S.A. = 981.7
