Answers

Answer 1
the answer is 16. It is 16 because you would use the formula (b/2)^2. so it would be (-8/2)^2. so it would then be simplified to (-4)^2. then simplify and it would give you 16

A bag contains 10 3/4cups of almonds. A serving of almonds is 1/4 cup. How many servings of almonds does the bag contain?

Answers

Answer:

43!

Step-by-step explanation:

There are 3 servings in 3/4 cups.

In each 1 cup there are four servings, so 4x10=40

40+3=43

The number of servings of almonds does the bag contains is 43.

Given that,

The bag contains [tex]10 \frac{3}{4}[/tex] almonds cups. And, the almonds served is [tex]\frac{1}{4}[/tex] cup.

Based on the above information, the calculation is as follows:

Here in [tex]\frac{3}{4}[/tex] cups there should be 3 servings.

And, for every 1 cup, there should be 4 servings

Therefore

[tex]= 4\times 10[/tex]

= 40

So, the total serving of almonds should be

= 40 +  3

= 43

Therefore we can conclude that the number of servings of almonds does the bag contains is 43.

Explain how to figure out the weight of a piece labeled with a letter by reasoning about the diagram (first answer gets brainliest) (please help ASAP)

Answers

1: 2.2+Z=6.8
2: you have to minus 2.2 and 6.8 to get 4.6 to even the weight
3: minus 2.2 n 6.8 =4.6

From the given figure, the equation is 2z+2.2=6.8 and the value of unknown number is 2.3.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1. From the given figure,

z+z+2.2=6.8

2z+2.2=6.8

2. From the given figure, one side there is rectangle with 6.8 and other side it is two pentagons with z and one square with 2.2

Now, remove weight of 2.2 on both the sides of balance, so the weight of the rectangle is 4.6.

The weight of rectangle is 4.6 is equal two pentagons

Then, the weight of each pentagon is 2.3

3. 2z+2.2=6.8

Subtract 2.2 on both the sides of an equation, we get

2z=4.6

Divide 2 on both the sides of an equation, we get

z=2.3

Therefore, from the given figure, the equation is 2z+2.2=6.8 and the value of unknown number is 2.3.

Hannah and Corrine are playing a game by rolling two cubes, each numbered 1 through 6. If the sum of the numbers on the cubes is 7, Hannah wins. If the sum is not 7, Corrine wins. Corrine says Hannah can win only if the following occurs:

1 on the first cube, 6 on the second cube
2 on the first cube, 5 on the second cube
3 on the first cube, 4 on the second cube

Which best explains if Corrine is correct?

Corrine is correct because there are only three ways to have a sum of 7 when the cubes are rolled.

Corrine is correct because there are no 7s on the cubes, so Hannah must roll a greater number on the second cube.

Corrine is not correct because Hannah can also roll doubles on the cubes, such as 3 on the first cube and 3 on the second cube or 4 on the first cube and 4 on the second cube.

Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

Answers

D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

Step-by-step explanation:

To get a sum of 7 by rolling two cubes, we need to get one of the combinations from the list below:

1 on the first cube, 6 on the second cube

or

6 on the first cube, 1 on the second cube

2 on the first cube, 5 on the second cube

or

5 on the first cube, 2 on the second cube

3 on the first cube, 4 on the second cube

or

4 on the first cube, 3 on the second cube

Therefore, the correct answer option is D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

Answer:

A

Step-by-step explanation:

its not d because hannah needs 7 not 6 and its not c because 3+3+4+4 is more than 7 and its not b because your 2nd roll doesn't have to be the highest because you can roll a 6 on your first roll and a 1 on your 2nd roll and get 7 and your first is the highest so therefore the answer is A.
