A bookcase is to have 5 shelves including the top. The height of the bookcase is to be 3 feet more than the width and only 20 feet of lumber is available. Use an equation to determine the width and height of the bookcase?
Answer:
The width and height is 1.375 and 4.375 respectively
Step-by-step explanation:
The computation of the width and height of the book case is shown below:
Let the width be w
And, the height be h
So, the following equations should be made
5w+3h=20 ......(i)
h = w + 3......(2)
Now
put the value of h in equation (1)
5w + 3(w + 3) = 20
5w + 3w + 9 = 20
8w = 20-9
8w = 11
w = 11 ÷ 8
= 1.375
And, the height would be
= 1.375 + 3
= 4.375

what is the surface area of this rectangle prison of 6 9 4
Answer:
You need to be specific on which is the length, height and width. Making the most basic assumption I would have to assume the answer is 228
Step-by-step explanation:
Formula for the surface area of a rectangular prism is A=2(wl+hl+hw)
A = 2 x (9 x 6 + 4 x 6 + 4 x 9)
A = 2 x (54 + 24 + 36)
A = 2 (114)
A = 228
An advertising company is curious about the impact the lengths of their television advertisements have on viewers' feelings about a product. They showed advertisements of different lengths to a group of volunteers and asked the volunteers to rate how positive they felt about the product on a scale of 111 to 101010. Their data is shown in the table below.
Avg. product rating/ 6.0/ 7.0/ 5.0/ 3.0/ 2.5
Ad length (seconds) 30/ 45/ 60/ 75/ 90
Answer:
Graph C
Step-by-step explanation:
Khan Academy
The correct graph that represents the given data effectively would be:
Graph C
The given data offers the average ratings of the product and the length of their advertisements in seconds.The third graph most effectively shows the data as it contains provided variables on the appropriate axis i.e. ad length on the x-axis and the average rating on the y-axis. The other graphs fail to represent the explanatory variable and the other variable effectively.Thus, 'graph C' in the scatter plot format is the correct answer.

Can someone plz help me with this one problem plz!!!
Answer:
10, 11, 12, 13
Step-by-step explanation:
2 + 8 = 10
3 + 8 = 11
4 + 8 = 12
5 + 8 = 13
x | y
2 | 10
3 | 11
4 | 12
5 | 13
y = x + 8, so take x, add 8 to it, and you get y
25 POINTS IF YOU ANSWER THIS AND PLEASE TELL ME WHAT K IS!!

Answer:
k = 2
Step-by-step explanation:
Find a coordinate of a point and its image. k is the ratio of those.
Here, it is easy to use the y-coordinate of J and J'.
Jy = -1
J'y = -2
k = J'y/Jy = -2/-1 = 2
The scale factor k is 2.
Kareem received $50 during his birthday. In addition, he saves $10 each week. Which equation can help find w, the number of weeks it will take Kareem to save a total of $200?
Answer: 50+10w=200 w=15
Step-by-step explanation:
So we know that Kareem starts off with $50 and every week he gains an additional $10 so as many weeks it takes to get $150 in addition to the $50 he already has to get $200. so $50+$10w=$200 where w represents the number of weeks it takes until the sum is 200
