The total cost of renovation depends on labor and materials. You decide to budget $25,000 towards labor. The amount, A, that each worker earns varies inversely to the number of workers on the job, n.
1) complete the table to indicate the amount earned for the given number of workers.
2) what do you notice about the product, A*n?
Answer:
see attachedA*n is the constant 25000Step-by-step explanation:
1)The amount A is said to vary inversely with n, so the equation relating the two is ...
A = k/n
The value of k can be found by multiplying this equation by n:
k = nA
Using values from the first line of the table, we find ...
k = (1)(25000) = 25000
So the relation we need to use to fill the table is ...
A = 25000/n
The filled table is attached.
__
2)As we saw in part 1, the product A*n is the constant of proportionality. It is a constant.

Answer:
x = 7
Step-by-step explanation:
The Triangle Sum Theorem tells us that the sum of the measures of a triangle's interior angles is 180. Using this information, we can make an equation to solve for x.
82 + 9x - 6 + 6x - 1 = 180
75 + 15x = 180 (Combine like terms)
15x = 105 (Subtract 75 from both sides)
x = 7 (Divide both sides by 15)
We can plug the value of x back into the equation to make sure of this answer.

4 slices of pizza cost $10.50. At this rate, what is the cost of 10 slices of pizza?
Answer:
$42.00
Step-by-step explanation:
Answer:
26.25
Step-by-step explanation:
If 4 slices are 10.50 $ then 8 are 21 $.We need 2 more to reach 10 slices and half of 4 is 2 so half of 10.50 is 5.25 so add 21 $ + 5.25 $ = 26.25.

Drag number to the blanks to write a quadratic function, f(x), that has zeros at x = 2 and x = 6. f (x) = x2 + ___ x + ___
Answer:
f(x) = x² - 8x + 12
Step-by-step explanation:
Given the zeros are x = 2 and x = 6 then the corresponding factors are
(x - 2) and (x - 6)
The function is then the product of its factors
f(x) = (x - 2)(x - 6) ← expand using FOIL
f(x) = x² - 8x + 12

the y intercept is -5
Step-by-step explanation:
because the equation is y=MX+b
Answer:
The y-intercept is -5.
Step-by-step explanation:
[tex]y=2x-5[/tex]
The equation is in slope intercept form.
[tex]y = mx+b\\\\m - \text{Slope}\\\\b - \text{Y-intercept}[/tex]
Since ' -5 ' is in 'b' 's place, it is the y - intercept.

A store has a 20% off sale on pants. The price of the pants before the discount was $48.
What was the sale price of the pants?
Answer:
$38.40
Step-by-step explanation:
20% of $48 is 9.60
48- 9.60= 38.40
Answer:
$38.40
Step-by-step explanation:
1. convert the percentage into a decimal by dividing x/100.
20/100 = 0.2
2. multiply by the original price.
0.2 * 48 = 9.6
3. subtract the discount.
$48 - $9.60 = $38.40

Step-by-step explanation:
Find a and b given f(x) = ax + b, f(1) = 7, and f(3) = -5.
Answer:
a = - 6, b = 13
Step-by-step explanation:
Given f(1) = 7 , that is f(x) = 7 when x = 1
f(3) = - 5 , that is f(x) = - 5 when x = 3
Substitute these values into f(x) = ax + b
a + b = 7 → (1)
3a + b = - 5 → (2)
Subtract (1) from (2) term by term to eliminate b
(3a - a) + (b - b) = - 5 - 7
2a = - 12 ( divide both sides by 2 )
a = - 6
Substitute a = - 6 into either of the 2 equations and solve for b
Substituting into (1)
- 6 + b = 7 ( add 6 to both sides )
b = 13
Alice earns £450 in wages per month.
She pays £200 rent per month.
Next month.
her wages will increase by 2%
her rent will increase by 5%
She says
"The increase in my wages will pay for the increase in my rent."
Is she correct?
You must show your working.
Answer:
false
Step-by-step explanation:
Since in the question it is mentioned that the wages would be increased by 2% and rent would increase by 5%
So, the increased value of both is
= $450 × 1.02
= $459
And,
= $200 × 1.05
= $210
As the wages are increased to $9 and the rent is increased to $10 since the amount is not equivalent to each other so the given statement is false
what is 4.2 less than 7.6
Answer: 3.4
Step-by-step explanation: 6-2 is 4 and 7-4=3 therefore it’s 3.4
The solution is 3.4
The value of the equation 4.2 less than 7.6 is 3.4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is expressed as
A = 4.2 less than 7.6
Substituting the values in the equation , we get
A = 7.6 - 4.2 be equation (1)
On simplifying the equation , we get
The value of A = 7.6 - 4.2
The value of A = 3.4
Therefore , the value of A is 3.4
Hence , The value of the equation 4.2 less than 7.6 is 3.4

What is the Y-Intercept of this table?
[tex]\left[\begin{array}{ccc}x&y\\5&16\\6&19\\7&22\end{array}\right][/tex]
Answer:
The Y-intercept is 4 or (0,4) in a plot
Step-by-step explanation:
To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13
(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)
Now continue until you reach 0 in the "x"
4 to 3 and 13 to 10
3 to 2 and 10 to 7
2 to 1 and 7 to 4
So the y-intercept is 4 or (0,4) in a plot
