Which angles are vertical to each other? Select all that apply.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

9 people

Step-by-step explanation:

40 + 18.25x = 124 + 7.75x

18.25x - 7.75x = 124 - 40

10.5x = 84

x = 84 ÷ 10.5

x = 8 people to EQUAL the same price as trampoline

Question is how many people must be invited to cost MORE, not the same.

If 8 equals, then anything above is more

Since there is no such thing as half a person, the answer is 9 people

Answer: 11 - 5 + 7

Step-by-step explanation:

In math, an expression is a combination of numbers, variables, functions(such as addition, subtraction, multiplication or division )

subtract 5 from 11 ( 11 - 5)

Then add 7 ( + 7)

Put these in expression form

11 - 5 + 7

28=4x+4

Step-by-step explanation

your total is $28 so that is you sum

you are adding $4 because of popcorn

and there are 4 people. (3 friends and you equal 4)

so 28+4x+4

x=6 by the way

Answer: The whole is divided into 3 equal parts. 2 out of 3 parts are shaded. 2/3 (two thirds) of the whole is shaded. 1/3 (one third) of the whole is not shaded.

Step-by-step explanation:

Answer:

Question 1: The whole is divided into 3 equal parts,

Question 2: 2 out of 3 parts are shaded.

Question 3: 2/3 of the whole is shaded,

Question 4: 1/3 of the wholde is NOT shaded.

Step-by-step explanation:

Question 1: You can see on the shape there are 2 lines and is divided into 3 parts(3 pieces separated), that means it is divided into 3 parts.

Question 2: if you look on the rectangle closely, you can see that 2 of the 3 squares are shaded.

Question 3: in question 1, we know that there are 3 pieces and in question 2, we know that 2 are shaded and that means that the fraction is 2/3.

Question 4: we know that 2/3 of the squares are shaded so that means we have to subtract 1 by 2/3 so 1-2/3=1/3 and that leaves us with 1/3 of the pieces are shaded.

Answer:

A 3/8

Step-by-step explanation:

2 digits with 9 options (as there is no 0).

and no double digits allowed.

that gives us 9 options for the first and then only 8 options for the second digit (as whatever was picked for the first, cannot be picked again for the second position).

in total

9×8 = 72

possible combinations.

and we are looking for the probability that the second digit is a prime number, when the first digit was already a prime number.

P(B|A) = P(B and A)/P(A)

we need prime numbers. what prime numbers are possible ?

2, 3, 5, 7

that means we have 4 desired cases out of 9 for theoretically each position (4/9), but again one less for the second position : 3 out of 8 (3/8).

that gives us as combined probability of A and B

4/9 × 3/8 = 12/72

the probability that the first digit is a prime number is again 4/9.

so, formally, we have for

P(B|A) = 12/72 / 4/9 = 12×9 / 4×72 = 12 / 4×8 =

= 3/8

Answer:

The answer is A, 3/8

Answer:

281 miles

Step-by-step explanation:

We know that 2 and a half hours is 150 minutes. If we divide 215 by 150, we get 1.43 miles per minute. We can multiply that by 60 to get 86 Miles Per Hour. She drives 2 Miles Per Hour faster for the next 3/4 hour. This means she drives 88 MPH for the next 3/4 hour. So, we can multiply 88 by 3/4 to get 66.

She drove 66 miles in 3/4 hour

She drove 215 miles in 2 1/2 hours

66+215 = 281 miles

Hi where are options. Hope you understand mr

Answer:

c and b

Step-by-step explanation:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion

(Hope this helps some way)

two-pairs should be your answer.

Answer:

Step-by-step explanation:

1436.45 square feet more than the other lawn

Step-by-step explanation:

15+12x=13x+5

we move all terms to the left :

15+12x-(13x+5)=0

We get rid of parentheses

12x-13x-5+15=0

We add all the numbers together , and all the variables

-1x+10=0

We move all terms containing x to the left , all other terms to the right

-x = -10

x = -10/-1

x= +10

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

You already said the answer. There are 400 billion birds in the world. ("if there are 400 billion birds in the world...")

Also, if you wanted an approximate calculation of everything, you would have to tell us how many years there are. Is this a trick question?

Answer:

As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40.

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

\( \frac{4}{7} \times y\)

Remainder =

\(y - \frac{4}{7}y = \frac{3}{7} y\)

Amount spent on frozen foods = two-thirds of remainder = $22

\( = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y\)

\(\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77\)

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

\( = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44\)

Negative 3, negative 2.4, negative 1.5, negative 2 and one-fourth, negative 1 and one-eighth
