Answer 1

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

How to simplify the expression?

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

help pleaseeeeeeee!! John is baking rectangular cakes. The first cake he baked was 3 inches wide and 5 inches long. The second cake he baked was 6 inches wide and 10 inches long. The third cake he baked was 12 inches wide and 20 inches long. If John continued this pattern, what would the dimensions of his fourth cake be?

Answers

Answer:

Step-by-step explanation:

try 40 inches long and 24 inches wide

and 3 x 2 = 6 6 x 2 = 12 12 x 2 = 24

The number are getting multiplied by 2 each time so the fourth cake would be 24 inches wide and 40 inches long.

Which of the following rounds most closely to 1?
A. 1/5

C. 4/8

D. 2/3

Answers

Answer:4/5

Step-by-step explanation:

1/5 is closer to zero than 4/5 so we know it can't we that one.

4/8 is equal to 1/2, and 4/5 is closer to 1 than 1/2 is

2/3 multiplied by 5 is 10/15, while 4/5 multiplied by 3 is 12/15

by getting the same denominator we can see that 4/5 is the closest fraction to zero.

The answer is b 4/5 is closer to 1

Drag and drop one set of parentheses into the expression below so that it's value when simplified is 31. Where would these ( ) go? _2_*4^2_+_square root36_-_13_

Answers

Answer:

2 * (4^2 + squared root of 36) - 13

since the space where the _ are, that's where the parenthyeses would be placed. If you place these around 2, you get 25, is around 4^2, it's also 25, if placed around square root of 36, it will also be 25, but if placed around -13, it's -46. But place then around 4^2 + the square root of 36, then you will get your answer of 31 simplified.

The answer is 2* (4^2 + squared root of 36) - 13

Fabiola’s basketball team practices 4.25 hours each week basketball season is 14 weeks long .how much time does Fabiola’s spend in practice during the season? and show how to do the problem

Answers

Answer:

59.5 hours

Step-by-step explanation:

Since Fabiola has basketball practice for 4.25 hours each week and we need to find how much she practices for 14 weeks, you have to multiply.

4.25 x 14 = 59.5

In order to determine the total time, we simply need to multiply 4.25 hours by 14, since the length of time is dependent to the number of weeks.

= (14)(4.25)

=59.5

Final answer:
Fabiola's team spend 59.5 hours in 14 weeks.

I’m pretty good with functions, all the numbers in the domain can only have one range ☝ so if for example, 3 had a arrow going to 5 and 7. That wouldn’t be a function, because 1 function has 2 domains, and since you have no range its not a clarified answer meaning that there’s following domain to go with the range so I wouldnt really say it’s a function because the domains have not range to go to, hope this helped!! :D
