A worker is spray painting doors. It takes LaTeX: \frac{2}{5} 2 5 of a can of spray paint to paint 1 door. The worker has 2 cans of spray paint total. How many doors can the worker paint? Group of answer choices
Answer:
5 doors
Step-by-step explanation:
Can of spray paint : door painted = 2/5 : 1
The worker has 2 cans of spray paint total.
How many doors can the worker paint?
Let x = number of doors the worker can paint
Can of spray paint : door painted
2 : x
Equate both ratios
2/5 : 1 = 2 : x
2/5 ÷ 1 = 2/x
2/5 × 1/1 = 2/x
2/5 = 2/x
Cross product
2 * x = 5 * 2
2x = 10
x = 10/2
x = 5 doors
The worker can paint 5 doors with 2 cans of spray paint

Y is directly related to X, and Y is 81 when X is 27.
The constant of variation is ___
(there are no answer choices, it's just a type in box so i need an exact answer please! :))
Answer:
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
So, the constant of variation is 3.
Which function rule models the function over the domain specified in the table below?
f(x)
11
11
17
O f(x) =3x + 10
O fx) = 2x + 3
O fx)= 4x +5
O fx) =3x-10
The function with the domain is given by f ( x ) = 2x + 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the x values be x = { -7 , -1 , 3 , 4 , 7 )
Let the y values be y = { -11, 1 , 9 , 11 , 17 }
Now , the function is given as
f ( x ) = 2x + 3 be equation (1)
when x = -7
y = 2 ( -7 ) + 3
y = -11
when x = 7
y = 2 ( 7 ) + 3
y = 17
Hence , the function is f ( x ) = 2x + 3

a, b, and c represent three different digits. If you add up all of the six two - digit numbers that can be written with these digits, where you don't use the same digit twice in each number, then the sum will be 528. Find these digits.
Answer:
7, 8 and 9Step-by-step explanation:
Two-digit numbers are:
ab, ac, ba, bc, ca, cbSum of them is:
10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 52822a + 22b + 22c = 528a + b + c = 528/22a + b + c = 24The only option of three different digits with the sum of 24 is 7, 8 and 9
Answer:
The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb
The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
22a + 22b + 22c = 528
a + b + c = 528/22
a + b + c = 24 The only option/options of the three different digits with the sum of 24 is 7, 8 and 9.

A couch costs $350 to make. Before it is sold, it is marked up in price 80% more. How much will the couch cost?
Answer:$630
Step-by-step explanation:
What is 80% of 350?
Y is 80% of 350
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 80% * 350
Converting percent to decimal:
p = 80%/100 = 0.8
Y = 0.8 * 350
Y = 280
then u add 280 to 350
PLEASE HELP!!! A $950 computeris on sale for 15% off. If sales tax is 6% will this computer cost including tax?
Answer:
the computer will cost 864.5
Step-by-step explanation:
15% of 950 is 142.5.
950-142.5=807.5
6% of 950 is 57
Answer:
$855.95
Step-by-step explanation:
So We can first multiply the original price by 0.85 becuase its 15 percent off and we’re paying 85 percent of the original price basically.
You’ll get 807.50.
Now to find the sales tax we multiply that by 1.06 becuase the 100 percent is the price now and we’re just adding 6 percent so 1.06, and you’ll get 855.95
So no adding and subtracting and that takes off 2 steps and its way quicker
So the final answer is $855.95

The graphed line shown below is y = 5 x minus 10.
On a coordinate plane, a line goes through (2, 0) and (3, 5).
Which equation, when graphed with the given equation, will form a system that has no solution?
y = -5 x + 10
y = 5 (x + 2)
y = 5 (x - 2)
y = -5 x - 10
Step-by-step explanation:
For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.
Hence the answer is y = 5(x + 2).
