Answer:
31.5
Step-by-step explanation:
divide 42 by 4 you would get 10.5, then multiple 10.5 by 3 and you would get 31.5 thats the answer
Yoko needs 300 copies of her resume printed. Dakota printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies. If the number of sets of 100 resumes is represented by r, express the cost of the resumes c(r) algebraically as a piecewise function How much will 300 copies cost, including a sales tax of 4 1/2%? Round to the nearest cent.
Answer:
A. c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. $29.78
Step-by-step explanation:
A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:
c(r)=$19.5 when r represent an INTERGER and is less than 2
c(r)=$19.5+(r-2) ($9) (1+0.045)
c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2
Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%
Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)
Cost of 300 copies=$28.5+$28.5(0.045)
Cost of 300 copies=$28.50+$1.28
Cost of 300 copies=$29.78
Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78
Find the area of the triangle.
C = 133.5°, a = 45.7 ft and b = 37.1 ft
The area is
square ft.
(Simplify your answer. Type an integer or a decimal. Roun
Answer:
i think the answer is area = 1695.47 ft squared
Step-by-step explanation:
just do 45.7 x 37.1 since you’re finding area of a SQUARE which has all equal sides.

What is the rate of this answer ??
Answer:
Option (4)
Step-by-step explanation:
Let the input output values of the table are represented by the equation,
y = mx + b
Here m = rate
b = y-intercept
Since, at x = 0, y = -1 [Point given in the table]
y-intercept 'b' = 0
Rate = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points given in the table.
If the points are (-2, -5) and (-1, -3),
Substitute the values in the formula,
Rate = [tex]\frac{(-5)-(-3)}{(-2)-(-1)}[/tex]
= [tex]\frac{-5+3}{-2+1}[/tex]
= 2
Therefore, Option (4) will be the answer.
Use the linear combination method to solve the system of equations. Explain each step of your solution.
5x - y -= 3
x + 2y = 5
Answer:
1)y=-3+5x
2)y=5/2-1/2x
Step-by-step explanation:
for both equations
1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)
2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides
3) your equation should now be y=5x-3

This relation is an inverse variation. {(–1, 8), (4, –2), (–2, 4)} Which equation represents this relation?
Answer:
[tex]y = -\frac{8}{x}[/tex]
Step-by-step explanation:
Given
Inverse Variation:
[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]
Required
Determine the equation of the relation
An inverse relation is represented as:
[tex]y = \frac{k}{x}[/tex]
Where k = constant of variation
Make k the subject:
[tex]k = xy[/tex]
When x = -1, y = 8
So, we have:
[tex]k = -1 * 8[/tex]
[tex]k = -8[/tex]
When x = 4, y = -2
[tex]k = 4 * -2[/tex]
[tex]k = -8[/tex]
When x = -2, y = 4
[tex]k= -2 * 4[/tex]
[tex]k = -8[/tex]
From above calculations, we've established that:
[tex]k = -8[/tex]
Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]
[tex]y = \frac{-8}{x}[/tex]
[tex]y = -\frac{8}{x}[/tex]
Hence, the equation is:
[tex]y = -\frac{8}{x}[/tex]

what must be the value of a and b for PQRS to be a parallelogram?
Answer:
a = 2
b = 4
Step-by-step explanation:
In parallelogram opposite sides are equal.
4a + b = 2a + 8
4a - 2a + b = 8
2a + b = 8 -----------------(I)
b = 8 - 2a
11b - 10a = 6b
11b - 6b -10a = 0
5b - 10a = 0 ---------(II)
Substitute b = 8 - 2a in equation (II)
5*(8-2a) - 10a = 0
5*8 - 2a * 5 - 10a = 0
40 - 10a - 10a = 0
40 - 20a = 0
-20a = - 40
a = -40/-20
a = 2
Plugin a = 2 in equation (I)
2*2 + b = 8
4 + b = 8
b = 8 -4
b = 4

Answer: the equation of this parallel line would be: Answer: y = 5x - 6
Step-by-step explanation:
Slope of the parallel lines are same
So, m= 5
(3,9)
Equation: y - y1 = m(x -x1)
y - 9 = 5(x - 3)
y - 9 = 5x - 3*5
y -9 = 5x -15 {add 9 to both sides}
y - 9 + 9 = 5x - 15 + 9
y = 5x - 6

The perimeter of a right triangle is 60 feet and the area is 150 square feet. If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle? A. 500 ft. B. 600 ft. C. 7120 ft. D. 8640 ft.
Answer:
B. 600 ft
Step-by-step explanation:
The formula for the Perimeter of a right triangle = Side a + Side b + Side c
The perimeter of a right triangle is 60 feet
If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?
Hence, the perimeter of the new right triangle = 10 × 60ft
= 600ft
