Answer:
Column 1 choose option 1 (x,y) --> (3/2x,3/2y)
Column 2 choose option 2 (x,y) --> (3/2x,3/2y)
Step-by-step explanation:
Focus on just Point S to go from (6,2) to (9,3) you would multiply 6*3/2 and 2*3/2. So, the scale factor is 3/2.
Answer:Column 1: 1 (x,y) --> (3/2x,3/2y)
Column 2: 2 (x,y) --> (3/2x,3/2y)

Answer: 235.5 yd^3
Step-by-step explanation:
Step 1. Find the radius.Remember the formula; pi * r^2 * h/3
Since the diameter is 2 times the radius, d=10, we have to split it by 2 {10/2 =5}
Step 2. Simplify. 3.14 * 5^2 * 9/3
Step 3. PEMDAS, start with exponents. 3.14 * 25 * 9/3
Step 4. PEMDAS, divide the numbers.
3.14 * 25 * 3
Step 5. Multiply 25 * 3.
3.14 * 75
Step 6. Simplify. 235.5 yd^3
Answer:
235.5 yd^3

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answer:
Step-by-step explanation:
To make the race close, the length of the race should be 450 meters.
Here's the reasoning behind the answer:
Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.
The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.
During this time, Henri would have walked a distance of 1 x 18 = 18 meters.
So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).
To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.
Let's call the total distance of the race "d."
So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).
We can set up an equation to solve for d:
d/1 = (d + 27)/2.5
Solving for d, we get:
d = 450
So, the race should be 450 meters long for Henri to win in a close race.

A photo of a beetle in a science book is increased to 778% as large as the actual size. If the beetle is 15 mm, what is the size of the beetle in the photo
Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.

help me asap please Which expression calculates the speed in feet per second of an object that travels a distance of 40 feet every 10 seconds?
Responses
A-10 divided by 40
B-10 plus 40
C-40 divided by 10
D-40 times 10
Answer:
C.
Step-by-step explanation:
Speed can be calculated by distance over time. (or in a fraction)
Therefore, the answer is C because 40÷10 equals 4 ft./h.

A bakery has a fixed cost of $119.75 per day plus $2.25 for each pastry.The bakery would like to keep its daily cost at or below $500 per day. Which inequality shows the maximum number of pastries, p, that can be baked each day?
a. [tex]2.25 + 199.75p \leq 500; p\leq 416[/tex]
b. [tex](119.75 + 2.25)p \leq 500; p \leq 409[/tex]
c. [tex]119.75 + 2.25p \leq 500; p \leq 169[/tex]
d. [tex]2.25p - 119.75 \leq 500; p \leq 275[/tex]
Answer: 169
Step-by-step explanation: We can set up an inequality. Subtract 119.75 to both sides: Divide 2.25 by both sides: So the maximum number of pastries that can be baked each day is 169. hope that helped x

What is the area of this trapezoid?
Enter your answer in the box.
Answer:
153 units squared
Step-by-step explanation:
first, multiply 10 x9 to find the area of the rectangle, which is 90
then find the area of the triangle. The formula for area of a triangle is
A=1/2bh
so, 7 x 9= 63 divided by 2 is 31.5
since there are 2, multiply 31.5 x 2= 63
add 63 to 90 which is 153
Answer: 153 sq. units
Step-by-step explanation:
Base a = 10
Base b = 7x2 = 24
Height = 9
area of trapezoid = 1/2 * (a+b) * h
= 10+24 * 9 /2
= 306/2 = 153

You have a bag of marbles with 630 marbles in it: 110 red, 230 green, and 290 blue. You pull out 1 marble, record the color, and replace it.
After you do this 100 times, the table shows the number of times each color was drawn:
Red Green Blue Total
21 35 44 100
Give exact, reduced answers.
a) What is the theoretical probability of drawing a blue?
b) What is the experimental probability of drawing a blue?
Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

Step-by-step explanation:
The volume of a cone is computed using the formula volume = 1/3 pi r^2 h
for this cone r = 5 m h = 12 m
Plug in the values : volume = 1/3 * 3.14 * 5^2 * 12 = 314 m^3
Answer: 314 m^3
Step-by-step explanation:
The volume of a cone is [tex]\pi *r^2*h/3[/tex]
[tex]\pi = (3.14) *r^2 = (5^2)* h/3 = (12/3)[/tex]
Step 1. Simplify the expression. [tex]3.14 * 25 * 12/3[/tex]
Step 2. Simplify the expression again. [tex]3.14 *25*4[/tex]
Step 3. Multiply 25 and 4. [tex]3.14 * 100[/tex]
Step 4. Finish simplifying. [tex]314 .m^3[/tex]
