Answers
Answer:
Option (A)
Step-by-step explanation:
Given angle in the picture is neither a right angle (equal to 90°) nor obtuse angle (greater than 90°).
It's an acute angle which measures less than 90°.
Therefore, possible measure of the given acute ∠XYZ = 30°
Option (A) will be the answer.

Answers
Answer:
$60, $90
Step-by-step explanation:
Amount paid when 50% off
=$ 120 - 50/100 * 120 = $ 120 - $60 = $60
Amount paid when 25% off
=$ 120 - 25/100 * 120 = $ 120 - $30 = $90

midpoint of this line segment?
Answers
A. -3
B. 6
C. 5
D. -4
Answers
Answer:
B
Step-by-step explanation:
So we want to find the value of x.
Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:
[tex]JK=JI+IK[/tex]
We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:
[tex]2x-1=(2)+(x+3)[/tex]
On the right, add:
[tex]2x-1=x+5[/tex]
Add 1 to both sides:
[tex]2x=x+6[/tex]
Subtract x from both sides. The right cancels:
[tex]x=6[/tex]
And the value of x is 6.
Our answer is B.

The perimeter of a rectangle is 150. The length of the rectangle is 9 more than the width. Find the width.
Answers
Answer:
33
Step-by-step explanation:
Length = Width + 9
Perimeter = Length + Length + Width + Width
Perimeter = Width + 9 + Width + 9 + Width + Width = 150
4(Width) + 18 = 150
Subtract 18 from both sides:
4(Width) + 18 - 18 = 150 - 18
4(Width) = 132
Divide 4 on both sides:
[tex]\frac{4(Width)}{4} =\frac{132}{4}[/tex]
Width = 33

It takes 2 finish carpenters 8 days to do the work. Each finsh carpenter ears $37.50 per hour and works 7 hours per day. How much will it cost to hire the finish carpenters?
Answers
Answer:
Total cost= $4,200
Step-by-step explanation:
Giving the following information:
It takes 2 finish carpenters 8 days to do the work.
Each finish carpenter ears $37.50 per hour and works 7 hours per day.
To determine the total cost, first, we need to structure the total cost formula:
Total cost= 2*(37.5x)
x= total number of hours
Now, for 8 days:
Total hours= 8*7= 56
Total cost= 2*(37.5*56)
Total cost= $4,200

Step-by-step explanation:
79.99 x .15 = 11.9985
Final price: $67.99
Discount: $12.00

Ronald rents a car from Cheap Rent-a-Car for $25 plus $0.05 per mile. Dixon rents a car
from Great Cars for S40 plus $0.03 per mile. How many miles must they both drive for
their rental fees to be the same?
Answers
Answer:
750 miles
Step-by-step explanation:
Ronald
Rental fee = fixed cost + variable cost
= $25 + $0.05x
Where x = number of miles
Dixon
Rental fee = fixed cost + variable cost
= $40 + $0.03x
How many miles must they both drive for their rental fees to be the same?
Equate the two equations
$25 + $0.05x = $40 + $0.03x
Collect like terms
0.05x - 0.03x = 40 - 25
0.02x = 15
Divide both sides by 0.02
x = 15 / 0.02
= 750 miles
