Answer:
I will let you answer this after reading below
Step-by-step explanation:
a=area
[tex] a = \pi {r}^{2} [/tex]
[tex]r = d \div 2[/tex]
write a in terms of d
[tex] a = \frac{\pi {d}^{2}}{ 4}[/tex]
since it's a semicircle divide a by 2 and that's your answer

Step-by-step explanation:
find the surface area of a prism with the length of 6m a width of 2m and a height of 10m.
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
Hope this helps!! :)

Answer:
25
Step-by-step explanation:
because if you do 1000 divided buy 25 its 69420 so if you do 69420 divided by 69420 its 1 and 1x1000 its 1000 divided by 54 its 25 so its 25
The average human reaction time from eye to finger is 0.16 second. How is this expressed as a fraction?
Answer:
4/25 seconds
Step-by-step explanation:
the second (0.16) is in two decimal places, so divide 16 by 100
[tex]\frac{16}{100}[/tex]
to express in the simplest form, divide the numerator and the denominator by 4
= [tex]\frac{4}{25}[/tex]
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?
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

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.
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.

A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
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

Find the intercept and slope in the graph, and find the aquation for the function.
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

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
Option (2) will be the answer.
Homes appreciate 8% every year. What is the multiplier?
Answer:
1.08
Step-by-step explanation:
Home appreciates 8% every year. Since 8% is increased every year , therefore 1 + 8/100 will be multiplied to the initial cost every year .
Hence the multiplier is 1.08 .The number of school buses needed to transport students on a field trip is given by the function

$1,004.80 4
$1,009.60 8
$1,013.20 11
D.
Balance Due Number of Months
$1,005 5
$1,007 7
$1,012 12
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

A washer and a dryer cost $726 combined. The washer costs $76 more than the dryer. What is the cost of the dryer?
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
