Estimate the side length of a square that has a 9cm long diagonal

Answers

Answer 1
s^2 + s^2 = 9^2 => 2s^2 = 81 => s^2 = 81/2 => side length s = 9(sqrt(2))/2 = 6.37 cm.
Answer 2
Answer:

9cm

Explain:

If it’s a square all sides are equal. So if one side is 9cm all sides are 9cm

Which sequence of transformations proves that shape I is similar to shape II?
A. a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2
B. a reflection across the x-axis, and then a dilation by a scale factor of 3
C. a reflection across the x-axis, and then a dilation by a scale factor of 2
D. a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 3

Answers

Answer:

C

Step-by-step explanation:

1) you can tell that one of the pre-images sides is 2 units and the corresponding image's is 1 so you can assume the scale factor is 2, also the preimage is on one side of the x axis and the image is on the other.

Answer:  C. a reflection across the x-axis, and then a dilation by a scale factor of 2

Step-by-step explanation:

We see that the shapes are on the opposite sides of the x-axis, and vertical lines are still vertical.  A 90° rotation would have made the vertical lines horizontal.

We see that the line that was 1 unit long is now 2 units. The line that went from 4 to 6 goes from 8 to 12. This is evidence of a dilation bt a factor of 2.

Four out of five customers ride their

bikes to the shop. On Saturday, 18

customers came in without riding their

bikes. How many rode their bikes?

Answers

72 rode their bikes.

Explanation:
18 did not ride their bike, which makes 1/5. Multiply 18 by 5, which will give you the other 4/5. Subtract 18 from 90, and you will get 72.

The number of people rode their bikes are 72.

Given that, four out of five customers ride their bikes to the shop.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

4/5 customers ride their bikes to the shop.

Number of customers do not ride their bikes to the shop = 1/5

On Saturday, 18 customers came in without riding their bikes.

Let the total number of people ride the bike to shop be x.

So, 1/5 × x = 18

⇒ x = 90

Now, 90-18=72

Therefore, the number of people rode their bikes are 72.

Answers

Answer: 11, 13, 15

Let the first integer be x.  The second integer is (x + 2) and the third integer is (x + 4).

x - (x + 4) = (x + 2) - 9

4 = x - 7

x = 11

Jill wants to make melonade for her family reunion. She needs enough lemonade for 60 people to each have 1 cup. Write a proportion Jill could use to find the number of gallons of lemonade Jill will need to make. (* do not solve ** must include units )

Answers

Answer:

[tex]\frac{x gallons}{60 cups} =\frac{1 gallon}{15 cups}[/tex]

Step-by-step explanation:

There are about 15.77 cups in a gallon, but I rounded down because .77 cup isn't a full cup. If you aren't supposed to round, use 15.77 instead of 15 and you should get 3.804... gallons needed. If you are supposed to round to nearest whole, use 15. You may have to adjust it depending on the instructions. I hope this helps. Feel free to comment any questions, I will try to respond.
