I WILL GIVE BRAINLYEST

Answers

Answer 1

Answer:

270 minutes in all

Step-by-step explanation:

First, if we know that Deena spent 45 min painting, and that Clara spent 30 min more, than to find how much Clara painted you do 45 + 30 which equals 75. To find Adam, you do 75 x 2 which = 150.

150 + 75 + 45 = 270

Hope this helps!

Answer 2

Ok so you can work your way back. It says Deena has spent 45 minutes painting and Clara has spent 30 minutes more than Deena. 45+30 is 75. Next it says Adam spent twice as many minutes as Clara and we now know Clara spent 75 minutes. 75 times 2 is 150 minutes.
45+75+150= 270 minutes
(45 for Deena, 75 for Clara, and 150 for Adam)

Step-by-step explanation:

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

what is the solution to the systems of equations? equations - 3x-y= -17 , x-y= -13

Answers

Answer:

x=1 y=14

multiply x-y=-13 by 3 so the x would cancel out. solve for y

then plug in y to one of the equations to get x

Answer: the answer is x= -2 , y=11

Step-by-step explanation:

First

1: we have to find the answer for x in x-y= -13

2: add y on both sides of the equation

3: we will get x= -13+y

Second

1: Substitute x in 3x-y= -17 with x=-13+y

2: then you will get 3(-13+y)-y= -17

3: multiply 3 with -13 and y

4: you will get -39+3y-y =-17

5: add 3y and -y

6: you will get -39+2y= -17

7: add 39 on both sides of the equation

8: you will get 2y=22

9: divide 2 on both sides

10: you will get y= 11

Third

1: plug 11 for y in x= -13+y

2: then you will get x= -13+11

3: you will x= -2

So x= -2 and y= 11

A stepladder has an angle of elevation of 60° with the front of the house. The length of the stepladder is 24 feet. At what height does the stepladder meet the house?

Answers

Answer:

20.78 feets

Step-by-step explanation:

Based on the solution diagram attached below :

The height at which the step ladder meets the house can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin θ = h / 24

Sin 60 = h / 24

0.8660254 = h/24

Height, h = 0.8660254 * 24

Height, h = 20.78 feets

Cindy owns a rectangular lot that is 18 yards long and 45 feet wide.
She is going to cover the lot with square pieces of sod. If the sod costs $12 per square yard, how much will Cindy pay to completely cover the lot with sod?

Answers

Answer:

$3240

Step-by-step explanation:

First you need to find the area of that lot. Area of a rectangle = length x width. But you also have mixed units...yards and feet. Since the price of the sod is in square yards, we'll convert the 45 feet to yards. 3 feet = 1 yard, so divide 45 by 3, = 15 yards.

18 x 15 = 270 square yards

then you multiply that by the $12/square yard

270 x 12 = $3,240
