If the shapes are scaled copies, select a reasonable scale factor that could be applied to shape 2 to create shape 1?
Answer: 1.8
Step-by-step explanation:
First option is wrong because using a scale factor of 1 would result in the same shape.
Second option is wrong because using a scale factor less than 1 would result in shape 2 becoming smaller.
Third option is most likely as shape 1 looks almost double the size of shape 2.
Fourth option is unlikely because shape 2 would have to expand more than 4/3 to be as large as shape 1.
Fifth option is wrong because the scale factor cannot be less than 1.

So confused please help this is a 30 60 90 triangle
Answer:
x = 10, y = 20
Step-by-step explanation:
The ratio of the sides of a 30-60-90 triangle is a:[tex]\sqrt{3}[/tex]a:2a. The side given is the one that is the [tex]\sqrt{3}[/tex]a. This means that you can do [tex]10\sqrt{3}[/tex] divided by [tex]\sqrt{3}[/tex] to get that a = 10. That means that side x is 10. For side y, it is 2a, or 2 * 10 = 20.
-8x+3x+16=17 simplify
Answer:
x = -1/5
Step-by-step explanation:
-8x + 3x = -5x
17 - 16 = 1
-5x = 1
-5x/-5 = 1/-5
x = -1/5
Dulce flipped a coin three times. What is the probability that she will get exactly 2 tails?
Answer:
0.38
Step-by-step explanation:
0.38 is the probability of getting exactly 2 Tails in 3 tosses.
Answer:
For exactly 2 tails, the possible outcome would be 0.38.
Step-by-step explanation:
step 1: Find the total possible combinations of sample space S
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
S = 8
step 2: Find the expected or successful events A
A = {HTT, THT, TTH}
A = 3
step 3: Find the probability
P(A) = Successful Events / Total Events of Sample Space
= 3 / 8
= 0.38
P(A) = 0.38
0.38 is the probability of getting exactly 2 Tails in 3 tosses.
Hope this helps :)

Find the next 3 term of geometric sequence
Answer:
32, 64, 128
Step-by-step explanation:
Let us start by looking at the geometric progression. A geometric progression multiplies each number by a constant, which we can name r, to get the next term. Let us find this constant:
16÷8=2
8÷4=2
Both expressions confirm that our r, the constant, is indeed 2.
To find the next few terms, we simply multiply by r:
1. 16r=16×2=32
2. 32r=32×2= 64
3. 64r= 64×2 = 128
I hope this helps! Please let me know if you have any further questions :)
Select all the values for r that indicate a positive slope for the line of best fit.

Answer:

0.8
Step-by-step explanation:
i just did it and was right
The required values of the r that shows the positive slope are 1, 0.5, and 0.8.
Given that,
To select the values for r that indicate a positive slope for the line
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
y -y₁ =(y₂ - y₁) / (x₂ - x₁) (x - x₁)
Here,
The positive slope is defined as the positive value of the r, not also zero because zero represents the contant nature of the function while the positive slope shows the increasing nature of the function or curve.
Thus, the required values of the r that shows the positive slope are 1, 0.5, and 0.8.

If a block is moving at a constant speed of 4 m/a and travels for 15.43 s, what is the distance did it travel in km, show all work.
Answer: It traveled 0.06172 km.
Step-by-step explanation:
Given: Speed of block = 4 m/s
Time taken by block = 15.43 s
To calculate: Distance covered by it in km.
We know that,
[tex]Distance = speed \times time[/tex]
So distance covered by block = [tex]4\times15.43[/tex]
= [tex]61.72\ m[/tex]
Since 1 kilometer = 1000 meters.
So,
[tex]61.72\ m=\dfrac{61.72}{1000}\ km=0.06172\ km[/tex]
Hence, it traveled 0.06172 km.
Mary can run 5 kilometers in 18.75 minutes.
At this rate, how long would it take to run 8 kilometers?
Answer:
30 minutes
Step-by-step explanation:
Find the unit rate (time per SINGLE kilometer).
5/5=1 18.75/5=3.75
Multiply 3.75 (unit rate) by 8.
3.75 x 8=30
Ms. Lee invites the other math teachers to
go
to the movies. It costs $25 for a large
pizza to share, and $8.00 per movie
ticket. She spent a total of $49.00. How
many teachers total went to the movies?
This is 7th grade math it’s 2 step equations
Answer:
3 adults
Step-by-step explanation:
What I did is subtract the price of the large pizza from the total
49-25 = 24
so the reamining total is $24 so i divded that by the cost of each ticket $8
24÷8= 3
so the adults went to the movies
