Find the area of circles whose diameters
(a)14 cm
(b) 28 cm
Answer:
(a) 153.93804
(b) 615.75216
Step-by-step explanation:
(a) A=πr2
14 divided by 2 =7
=π*7 squared =153.93804
(b) A=πr2
28 divided by 2= 14
=π*14 squared=615.75216
Suppose you have a bag with 50 letters tiles in it and 9 of the tiles are the letter m. If you pick a letter tule at random from the bag, probability that is the letter m is 9/50
Answer: True- [tex]\dfrac{9}{50}[/tex]
Step-by-step explanation:
Given
There are 50 letter tiles
9 of them is m letter
Favorable outcomes to draw an m letter tile is 9
The total ways to draw a single tile is 50
Probability is the ratio of favorable to the total outcomes
[tex]P=\dfrac{9}{50}[/tex]
So, the given statement is true
Suppose you have a bag 40 marbles and 20 of them are white if you choose a marble without looking the pribability that you choose a white marble is 20/40 describe the probability
Answer:
0.5
Step-by-step explanation:
If there are twenty white marbles in a bag of 40, then the chances of drawing a white marble is 20/40, or 0.5: one chance in two of drawing white.
Please help me with question number 2
Answer:
2. The area of the side walk is approximately 217 m²
3. The distance away from the sprinkler the water can spread is approximately 11 feet
4. The area of the rug is 49.6
Step-by-step explanation:
2. The dimensions of the flower bed and the sidewalks are;
The diameter of the flower bed = 20 meters
The width of the circular side walk, x = 3 meters
Therefore, the diameter of the outer edge of the side walk, D, is given as follows
D = d + 2·x (The width of the side walk is applied to both side of the circular diameter)
∴ D = 20 + 2×3 = 26
The area of the side walk = The area of the sidewalk and the side walk = The area of the flower bed
∴ The area of the side walk, A = π·D²/4 - π·d²/4
∴ A = 3.14 × 26²/4 - 3.14 × 20²/4 = 216.66
By rounding to the nearest whole number, the area of the side walk, A ≈ 217 m²
3. Given that the area formed by the circular pattern, A = 379.94 ft.², we have;
Area of a circle = π·r²
∴ Where 'r' represents how far it can spread, we have;
π·r² = 379.94
r = √(379.94 ft.²/π) ≈ 10.997211 ft.
Therefore, the distance away from the sprinkler the water can spread, r ≈ 11 feet
4. The circumference of the rug = 24.8 meters
The circumference of a circle, C = 2·π·r
Where;
r = The radius of the circle
π = 3.1
∴ For the rug of radius 'r', C = 2·π·r = 24.8
r = 24.8/(2·π) = 12.4/π = 12.4/3.1 = 4
The area = π·r²
∴ The area of the rug = 3.1 × 4² = 49.6.
3y - 21 = 12x How to solve for y
Answer:
y=4x+7
Step-by-step explanation:
Let's solve for y.
3y−21=12x
Step 1: Add 21 to both sides.
3y−21+21=12x+21
3y=12x+21
Step 2: Divide both sides by 3.
3y /3 = 12x+21 /3 y=4x+7

Assuming the point A has coordinates (2,3) and the center of dilation is the origin.
Then the image of point A under a dilation of scale factor of 4 is (4∗2,4∗3)=(8,12)(4*2,4*3)=(8,12)(4∗2,4∗3)=(8,12)
Hence A(2,3)→A′(8,12)A(2,3)\to A'(8,12)A(2,3)→A
′
(8,12)
In general the rule for a dilation of scale factor of k is (x,y)→(kx,ky)(x,y)\to(kx,ky)(x,y)→(kx,ky)

Answer:
99
Step-by-step explanation:
The following figure is a trapezoid with the following dimensions
Height = 9ft
Shorter Base Length = 6ft
Longer Base Length = 16ft
The area of a trapezoid can be found using this formula
[tex]A=\frac{a+b}{2}h[/tex]
where a and b = bases and h = height
Given all the information needed we plug in the values into the formula
[tex]A=\frac{6+16}{2} 9\\6+16=22\\\frac{22}{2} =11\\11*9=99\\A=99ft^2[/tex]
So we can conclude that the area of the trapezoid is 99 ft²
Answer:
Formula of a trapezoid:
Base 1 + Base 2 x H x 1/2
In this case:
Base 1 (6) + Base 2 (16) x Height (9) x 1/2
= 99
Y=1/5x+14 when b=7? how do i solve this?
Answer:
Step-by-step explanation:
Y = 1/5 x + 14 where b = 7
Result:
x + 70 = 5 Y
Geometric figure:
line
Alternate forms:
x = 5 Y - 70
x - 5 Y + 70 = 0
Real solution:
Y = x/5 + 14
Solution:
Y = x/5 + 14
Integer solution:
x = 5 n, Y = n + 14, n element Z

What is the area of a square if its side length is 1 173 cm?
Answer:
The number 173 or 1,173?
1,173 x 1,173 = 1,375,929
Since all sides are equal in a square, one given length would be all the side lengths since all sides are equal in a square.
If the side length was 173 then:
173 x 173 = 29,929

The diameter of a basketball rim is 18 inches. A standard basketball has a circumference of 30 inches. What is the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim? Show your work.
Answer:
4.2 inches
Step-by-step explanation:
Basketball rim:
diameter = 18 inches
r = 18/2 = 9 inches
Ball:
Circumference of ball = 30 inches
2πr = 30 inches
[tex]2*3.14*r = 30\\\\r = \frac{30}{2*3.14}\\\\r = 4.8 inches[/tex]
Distance between the ball and the rim in a shot when the ball goes exactly in the center of the rim = radius of the rim - radius of the ball
= 9 - 4.8
= 4.2 inches

A doll manufacturer is trying to develop a special package for their Holiady Dolls in thee shape of a pyramid with a triangle base. A net of the package is shown below where F is the base of the pyramid. If the height of the package is 10 inches how many cubic inches of space are avalible for the company to fill?
Answer:
80 in³
Step-by-step explanation:
The volume of a pyramid is :
1/3 * base * height
Height = 10
The base is : the area of the triangle :
Area of triangle = 1/2 * base * height
Base = 6 inches ; height of triangle = 8 inches
Area of triangle = 1/2 * 6 * 8 = 24 inches
Base of pyramid = Area of triangle
Therefore ;
Volume of pyramid = 1/3 * 24 * 10
Volume of pyramid = 8 * 10
Cubic inches of space to fill = 80 in³

Find the radius of the sphere with the given volume. (15 points)
volume= 32/3 times pie yd cubed
show your work please
Answer:
r=1.37
Step-by-step explanation:
so first we have to change 32/2 to a decimal
to do that you have to divide 32÷3=10.66...7
the formula to find the radius when given the volume is r=([tex]\frac {v}{4*pi}[/tex])^1/3
r=([tex]\frac {10.6666666667}{4*pi}[/tex])^1/3
r= 1.37
then to check your work-
v=4/3π1.37^3
v=10.77
technically 10.77 and 10.6666666667 aren't equal but that's as close as it'll get
good luck :)

If £2000 is placed into a ban account that pays 3% compound interest per year how much will be in the account after 2 years
Answer:£2121.8
Step-by-step explanation:
Given
Principal money [tex]P=[/tex]£2000
rate of interest is [tex]R=3\%[/tex]
time period [tex]T=2\ yr[/tex]
The amount by compound interest is given by
[tex]A=P[1+\frac{R}{100}]^T[/tex]
Putting values
[tex]\Rightarrow A=2000[1+0.03]^2\\\Rightarrow A=2121.8[/tex]
So, after two years it will be £2121.8

Find the area of the parallelogram.
Answer:
Area of Parallelogram = B (base) x H (height)
The height = 35 in.
The base = 38 in.
Area = 35 in. x 38 in.
Area = 1330 in.^2 (1330 inches squared)
Answer: 1330
Step-by-step explanation:
Area = Base · Height
Base = 38
Height = 35
38 · 35 = 1330
Therefore
Area = 1330
