5. What single rigid motion can move the solid figure onto the dashed figure?
Translation
Dilation
Reflection
Rotation
Answer:
Rotation
Step-by-step explanation:
If you were to translate it, it wouldn't match up because it needs to be turned around. translation just involves moving the shape without rotating it. a dilation means that you're changing the size, and you're not supposed to do that for this problem. a reflection means that if you were to fold in between these two shapes, they would match up. They Don't in this case so that won't work. A rotation is the only way to get it so that all of the areas match up.

If Jamie is riding at 14 mph and cori is riding at 0.04km per minute, how far will each of yjem bike in two hours? 1 mile = 1.61 km use the equation D=V/T
Answer:
Jamie will have covered a distance of 45.08 km while Cori will be 4.8 km away
Step-by-step explanation:
Here, we want to know how far will each of both riders be in 2 hours time.
Jamie is riding 14 mph
This means the number of miles covered in two hours will be 14 mph * 2 = 28 miles
For comparison purposes, let’s convert this to kilometer.
Since 1 mile = 1.61 km, then 28 miles will be 28 * 1.61 km = 45.08 km
For Cori, he is riding at 0.04 km per minute
1 hour = 60 minutes
so 2 hours = 2 * 60 = 120 minutes
Since the speed is 0.04 km in a minute
Then the distance in 120 minutes will be 0.04 * 120 = 4.8 km
Answer:
The answer is B.
Step-by-step explanation:
0.40 km to miles 0.248548
Then 0.248548 x 120=2 hours
Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x= 63 . Which of these statements are true? Choose ALL that are correct. A. Robert's sales are represented by x when solving 3.5x= 63 . B. Robert's sister's sales total $18.00. C. Robert's sales total $25.20. D. Robert's sister's sales are represented by x when solving 3.5x= 63 . E. Robert's sales are represented by x when solving 2.6x= 63 .
Answer:
The answer is B. and D.
Step-by-step explanation:
if you solve the equation, you will find that X=18. Since his sister's sales are X, his sister sold 18. You multiply by 2.5 to find Robert's sales.
The correct statements are (B) and (D).
What is an equation?Two or more expressions with an equal sign are defined as an equation.
The given equation is x + 2.5x = 63.
Note that Robert's sales are 2.5 times his sister's sales, therefore, if his sister's sales is x then his sales are 2.5x
Hence, option (A) is incorrect, as Robert's sales are 2.5x.
Solve the equation as follows:
x + 2.5x = 63
3.5x = 63
x = 63/3.5
x = 18
Hence, option (B) is correct.
Since x=18, Robert's sales are:
2.5 × 18
= 45
Hence, option (C) is incorrect, as Robert's sales are $45, not $25.20.
Option (D) is already shown to be correct.
Option (E) is also incorrect, as option (D) is correct.
Hence, the correct statements are (B) and (D).

the number 102 is NOT a term in this sequence. explain why.
thanks :)
Answer:
common difference = 4
if 102 is a term in sequence n should have non decimal value
a +(n-1)d = 102
0r 6 + (n-1)4= 102

The formula d = rt gives the distance, d, traveled in time, t, at rate, r. A motorcycle traveled 67.2 mi in 1.2 h. What was its average speed (rate)? 30 mph 56 mph 66 mph 80 mph
Answer:
56mph
Step-by-step explanation:
If d=rt,
then s=d/t,
so if d=67.2 and t=1.2,
then 67.2/1.2=56
A crate to ship boxes of baseballs can hold 4 boxes that are each (6 x 6) * 2. How
many baseballs can be shipped in the crate, if each baseball takes a 1x1x I space?
Show your thinking using words, numbers, or labeled sketches.
Answer:
Each crate can contain 288 baseballs.
Step-by-step explanation:
Since one baseball takes up 1 × 1 × 1 space, and each box has 6 × 6 × 2 units of space, then the number of baseballs in one box is 6 × 6 × 2 ÷ 1 × 1 × 1 = 72 baseballs.
So, 72 baseballs can be contained in one box.
Now, since each crate contains 4 boxes, the number of balls contained in each crate is 1 × 4 boxes = 1 × 4 × 72 baseballs = 288 baseballs.
So each crate can contain 288 baseballs.

The formula for the surface area of a cylinder is 2\pi r(r+h)2πr(r+h)2, pi, r, left parenthesis, r, plus, h, right parenthesis where rrr is the radius of the cylinder's base and hhh is its height. A certain pole has a cylinder-like shape, where the base's radius is 101010 centimeters and the height is 222 meters. What calculation will give us the estimated surface area of the pole in square centimeters?
Answer:
2pi x 10 x 210
Step-by-step explanation:
The estimated surface area of the pole is 13194.68 square centimeters and this can be determined by using the given data.
Given :
The formula for the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].A certain pole has a cylinder-like shape, where the base's radius is 10 centimeters and the height is 2 meters.The following steps can be used in order to determine the surface area of the pole in square centimeters:
Step 1 - According to the given data, the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].
Step 2 - Now, substitute the values of 'r' and 'h' in the expression of the area of the cylinder.
[tex]A = 2\pi\times 10\times (10+200)[/tex]
