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

Challenge A new coffee shop sold cups of hot coffee and cups of iced coffee during its first two days. The ratio of cups of hot coffee sold to cups of iced coffee sold on the first day was . On the second day, the shop sold as many cups of iced coffee as the first day. The ratio of cups of hot coffee sold to cups of iced coffee sold on the second day was . How many cups of each type of coffee did the shop sell each day?
Answer:
1 day = 221 hot coffee cups and 117 iced coffee cups
2 day = 247 hot coffee cups and 234 iced coffee cups
Step-by-step explanation:
A new coffee shop sold 468 cups of hot coffee and 351 cups of iced
coffee during its first two days. The ratio of cups of hot coffee sold to cups of
iced coffee sold on the first day was 17 : 9. On the second day, the shop sold
twice as many cups of iced coffee as the first day. The ratio of cups of hot
coffee sold to cups of iced coffee sold on the second day was 19 : 18.
a) How many cups of each type of coffee did the shop sell the first day?
Let cups of hot coffee be denoted by x
Then
17x+ 19x= 468
or
36x= 468
x= 13
On the first day the number of hot coffee cups sold are 17y or 17*13= 221 cups.
On the second day the number of hot coffee cups sold are 19y or 13*19= 247 cups.
Similarly Let cups of iced coffee be denoted by y
Then
9y+18y= 351
27y= 351
y= 351/27= 13
On the first day the number of iced coffee cups sold are 9y or 13*9= 117 cups.
On the second day the number of iced coffee cups sold are 18y or 13*18= 234 cups.

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
Workout plus offers a membership for $30 each month plus a $100 startup fee. Fit Works offers a membership for $50 each month plus a $20 startup fee. After how many months will memberships to both gyms cost the same amount?
Answer:
4 months
Step-by-step explanation:
Let
x = number of months
Workout plus = 100 + 30x
Fit works = 20 + 50x
After how many months will memberships to both gyms cost the same amount?
Equate the cost of both gyms
Workout plus = Fit works
100 + 30x = 20 + 50x
100 - 20 = 50x - 30x
80 = 20x
x = 80/20
x = 4 months
After 4 months, memberships to both gyms cost the same amount

-5x+4y=7 y=-2x-8
x = 13, y = 18
hope this is right
Answer:
x=−3 and y=−2
Step-by-step explanation:
-5x+4(-2x-8)=7
-13x-32=7
-13x-32+32=7+32
-13x=39
divide both sides by -13
x=-3
substitute x for -3
-2(-3)-8= -2
y= -2
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 :)
i hope this helps

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
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.

how do you write a linear equation that relates y to x
Answer:
Find the slope and y-intercept of the line. = −2 Because the line crosses the y-axis at (0, 3), the y-intercept is 3. So, the linear function is y = −2x + 3. Use the graph or table to write a linear function that relates y to x.

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

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
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
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

Answer:
Area = 117 sq. ft.Perimeter = 44 feetStep-by-step explanation:
Given,
Length of the bedroom = 13 feet
Width of the bedroom = 9 feet
Therefore,
First Case:
Area of the bedroom = Length × Width
= 13 feet × 9 feet
= 117 sq. ft.
Second Case:
Perimeter of the bedroom = 2(Length + Width)
= 2 (13 + 9) feet
= 2 × 22 feet
= 44 feet
Hence,
Required area of the bedroom is 117 sq. ft. and perimeter of the bedroom os 44 feet (Ans)

use the cosine (cos)
Step-by-step explanation:
There are three trig functions:
sin
cos
tan
An easy way to remember which sides go with which function is the saying:
soh - cah - toa
so....breaking down the acronoym
sin refers to opposite over hypotenuse
cos refers to adjacent over hypotenuse
tan refers to opposite over adjacent
