Answer:
x = 0
r = 20
Step-by-step explanation:
9x - 7 = -7
add 7 to each side of the equation:
9x = 0
x = 0
-4 = (r/20) - 5
add 5 to each side of the equation:
1 = r/20
multiply both sides by 20:
r = 20
+7. +7
9x=0
9x/9=0/9
X=0
5)r=20

A- Parallelogram PQRS is also a rectangle
B- Parallelogram PQRS is also a rhombus.
C- Parallelogram PQRS is neither a rectangle nor a rhombus.
D- Parallelogram PQRS is both a rectangle and a rhombus, so it is a square.
Answers
Answer:
B- Parallelogram PQRS is also a rhombus.
Step-by-step explanation:
Given
Parallelogram PQRS with perpendicular diagonals
Required
Which of the option is true
(a) PQRS can be a rectangle
A rectangle do not have perpendicular diagonals.
Hence, (a) is false
If (a) is false, then (d) is also false
(b) PQRS can a rhombus
The diagonals of a rhombus are not perpendicular.
So (b) is true
No need to check for (c), since only option is true
Answer:
B- Parallelogram PQRS is also a rhombus.

find the surface area of a prism with the length of 6m a width of 2m and a height of 10m.
Answers
Answer: Surface Area= 184 m²
Step-by-step explanation:
Concept
The formula for the surface area of a prism: SA=2(wh+wl+hl)
Given
Width (w) = 2 m
Length (l) = 6 m
Height (h) = 10 m
Solve
SA=2(wh+wl+hl)
SA=2(2×6+2×10+6×10)
SA=2(12+20+60)
SA=2×92
SA=184 m²

Find the intercept and slope in the graph, and find the aquation for the function.
Answers
Answer:
Slope = 3
y intercept = -8
y = 3x - 8
Step-by-step explanation:
From the table shown, we can make use of the coordinate points
(0, -8) and (1, -5)
Slope m = y2-y1/x2-x1
m = -5-(-8)/1-0
m = -5+8/1-0
m = 3/1
m = 3
Slope = 3
The standard form of an equation is y = mx+b
b is the y intercept
Substitute m = 3 and (0, -8) into y = mx+b
-8 = 3(0) + b
-8 = b
b = -8
Hence y intercept is -8
Get the required equation
Recall that y = mx+b
y = 3x + (-8)
y = 3x - 8
This gives the required equation

Find the measure of the indicated arc
Answers
Answer:
200 degrees.
Step-by-step explanation:
By theorem of inscribed angle...
The measure of an inscribed angle is half the measure of the intercepted arc. [Theorem]
therefore, m(angle J) = half of m(arc CDE)
therefore, m(arc CDE) = 2 * m(angle J)
therefore, m(arc CDE) = 2 ( 100)
therefore, m(arc CDE) = 200 degrees.

A washer and a dryer cost $726 combined. The washer costs $76 more than the dryer. What is the cost of the dryer?
Answers
Answer:Cost of dryer=$325
Step-by-step explanation:
Let the dryer be represented as x
and the washer be x+76
such that the price of both can be written as
dryer + washer=$726
x + x+76=726
2x+76=726
2x=726-76
2x=650
x=650/2=325
Cost of dryer =x=$325

Answers
Answer:
The answer is B
Step-by-step explanation:
Given: Cory owes $1,000 to his bank. During the time of his loan, he is charged a real of 12% simple annual interest
To find: If he does not make any payments on his loan, draw table showing the relationship between the amount he owes and the number of months
Solution:
Loan amount P = $ 1000
Rate of interest R = 12 % per annum
SI = P * R * T /100
one month T = (1/12) Years
Interest per month = 1000 * 12 * (1/12) /100 = $ 10
Hence interest chaarges $ 10 per month
Cory owes to bank the loan amount and interest
Cory owes = 1000 + 10 n
where n is the number of months
Month Amount
0 1000
1 1010
2 1020
3 1030
4 1040
5 1050
6 1060
