In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?

A:Tasha, because she has the lowest ratio since 0.9 > 0.8
B:Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C:Jana, because she has the lowest ratio since 0.9 > 0.8
D:Jana, because she has the highest ratio since 27 over 30 is greater than 24 over 30

paul is going to a college where tuition for one year is $14,200. He has a scholarship worth $1,500 and a grant worth $200. He earns $125 a week at this job how many weeks does paul need to work to pay 50% of the remaining tuition.
hurry pl ill make brainliest

Answers

Answer: 50 weeks

First, since he has a scholarship and a grant, those are used to pay off college debt. So $1,500 + $200 = $1,700

Now we subtract that from the total debt.

$14,200 - $1,700 = $12,500

Now since we're only seeing how much can pay for HALF of his debt, we divide $12,500 by 2.

$12,500 ÷ 2 = $6,250

Finally, we have to divide by the amount of money he earns in a week to find the total weeks.

$6,250 ÷ $125 = 50

50 weeks!

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

6 on the first cube, 1 on the second cube

2 on the first cube, 5 on the second cube

5 on the first cube, 2 on the second cube

3 on the first cube, 4 on the second cube

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:

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.

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.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the number is 3 more than 20% of 40. Let the number be N. The number will be calculated as below.

N = 20% of 10 + 3

N =( 40 x 0.2 ) + 3

Under all 3 cases the cells attach to the substrate. You suspect that the reason the neuronal phenotype is supported by the laminin coating is due to the ability of laminin, but not collagen or poly-lysine, to bind to the integrin receptors RGD binding domain thus triggering a molecular cascade that leads to the expression of the neuronal phenotype.
