Answer 2

Answer:

Equation B and Equation C

Step-by-step explanation:

We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

Answer:

1/3

Step-by-step explanation:

So remember slope is y/x.

THe y value is 1st y minus 2nd y. In this case 6-4.  This gets you 2

The x value is 1st x minus 2nd x. In this case 8-2. This gets you 6

Put the y and x value into your fraction(y/x) and you get 2/6.

A​ student's course grade is based on one midterm that counts as ​% of his final​ grade, one class project that counts as ​% of his final​ grade, a set of homework assignments that counts as ​% of his final​ grade, and a final exam that counts as ​% of his final grade. His midterm score is ​, his project score is ​, his homework score is ​, and his final exam score is . What is his overall final​ score? What letter grade did he earn​ (A, B,​ C, D, or​ F)? Assume that a mean of 90 or above is an​ A, a mean of at least 80 but less than 90 is a​ B, and so on.

Answers

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

Proportion:

[tex]Midterm = 15\%[/tex]

[tex]Project = 25\%[/tex]

[tex]Assignment = 40\%[/tex]

[tex]Exam = 20\%[/tex]

Scores

[tex]Midterm = 66[/tex]

[tex]Project = 90[/tex]

[tex]Assignment = 75[/tex]

[tex]Exam = 66[/tex]

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

[tex]Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66[/tex]

[tex]Overall = 9.9 + 22.5 + 30 + 13.2[/tex]

[tex]Overall = 75.6[/tex]

Solving (b): The letter grade

From the question, we have:

[tex]A: Mean \ge 90[/tex]

[tex]B: 80 \le Mean < 90[/tex]

[tex]C: 70 \le Mean < 80[/tex]

The overall score falls in the following category:

[tex]C: 70 \le Mean < 80[/tex]

Because:

[tex]70 \le 75.6 < 80[/tex]

Hence, the letter grade is C

Malik has 3 boxes of baseball cards. Each box has 2 containers with 8 cards in each container.

Malik multiplies 8 x 2 and gets 16.

He then multiplies 3 x 2 and gets 6.

Then he multiplies 16 x 6 and comes to his final answer of 96.

Do you agree with Malik? Why or why not?

Answers

Answer:

no

Step-by-step explanation:

I think he did the first step correct, 8×2=16.

He did that because in each box there are 2 containers with 8 cards. so all together there are 16 cards in each box.

But then he should've multiplied 16×3=48 because there are three containers with the 16 cards.

What is the surface area of the rectangular prism shown above?​

Answers

Answer:

The surface area of the rectangular prism is [tex]160in^2[/tex].

Step-by-step explanation:

The surface area of a 3-dimensional shape is found by adding the area of each side of the shape together. In this case, the areas of each side of the rectangular prism are 20 in, 20 in, 50 in, 50 in, 10 in, and 10 in. Find the surface area by adding each area together and you'll get [tex](50*2)+(20*2)+(10*2)=100+40+20=160in^2[/tex].

A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.

Answers

Answer:

The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05

1

​  

⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x&lt;3.75}.

Step-by-step explanation:

In a sale, the price of a sofa is reduced by 70%. The sale price is £255 What is the price before the sale?

Answers

So 255 is 30% of the original price
So what we need to do is divide 255 by 30 to get one percent
255/30=8.5
So 8.5 is one percent of the original price or one hundredth. So to get the original price multiply that by 100 and get 850.
The original price was £850.

Answer:

850

Step-by-step explanation:

Price x .30 (100%-70%)=sales price

price x .30 = 255

price = 255/.30

price = 850
