A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
Answers
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21
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
Parallelogram PQRS has diagonals that are perpendicular. Based on that, which statement is most correct?
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.

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
7 1070
8 1080
9 1090

Answer:
Option (2)
Step-by-step explanation:
By the property of triangle,
If the sides of triangle are unequal, then the ratio of the measures of the angles will be equal to the ratio of their opposite sides.
Following this rule,
Angle opposite to the largest side will be biggest and angle opposite to the smallest side will be smallest.
Since, LJ > KL > JK
Therefore,
∠K > ∠J > ∠L

A rectangle has an area of 235.2m squared. One of the sides is 2.8m in length. work out the perimeter of the rectangle, please?
Answers
Answer:
P = 173.6 mSteps:
given:
A = 235.2 m²
S1 = 2.8 m
S2 = A/S1
S2 = 235.2/2.8
S2 = 84 m
P = 2(S1+S2)
P = 2(2.8+84)
P = 2 × 86.8
P = 173.6 m

Answers
Answer:
A

Answer:
A
[tex]f(x) = 3x - 2 \\ g(x) = 2x + 1 \\ (f - g)x = f(x) - g(x) \\ = (3x - 2) - (2x + 1) \\ = (3 - 2)x + ( - 2 - 1) \\ = x - 3[/tex]
