HELP ME DO THIS QUESTION PLEASE
Answer:
Volume: 864
Surface Area: 684
Step-by-step explanation:
Volume:
[tex]\frac{1}{2}(9 * 16 * 12) = 864[/tex]
Surface-Area: (Pretty Self-explanatory)
1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)
2. Base - 16 * 9 = 144
3. Height/Base - 12 * 16 = 192
4. 15 * 16 = 240
192 + 144 + 108 + 240 = 444
The Surface Area is 684.
the width w of a rectangular swimming pool is x+5 the area a of the pool is x^2+4-5
what is an expression for the length of the pool? step by step
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1
Answer:
x-1

Which graph represents a proportional relationship?
Answer:
C
Step-by-step explanation:
proportional will be linear and go through the origin
Answer:
C
Step-by-step explanation:
Proportional relationships must go through the origin (0,0) and must create a straight line
The only graph that shows a straight line going through the origin (0,0) is graph C, hence C represents a proportional relationship

Find the missing dimensions
Answer:
short base: 6 yards
long base: 8 yards
Step-by-step explanation:
Our understanding of your figure is shown below.
The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."
The short base is 6 yards.
__
The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.
The long base is 8 yards.
Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.

A book store is keeping track of the price of books according to the number of pages. Which scatterplot represents that bivariate data? A graph has price (dollars) on the x-axis and pages on the y-axis. A graph has books on the x-axis and pages on the y-axis. A graph has pages on the x-axis and price (dollars) on the y-axis. A graph has books on the x-axis and price on the y-axis.
Answer:
The graph has pages on the X-axis and price (dollars) on the Y-axis
Step-by-step explanation:
The X-axis will always have the independent variable (pages), while the Y-axis will have the dependent variable (number of pages). The pages will exist no matter how many there are, but the price is influenced by the number of pages.

3.3 + 10m = 7.81 find the value of m ill give brainliest
Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451
Answer:
0.451
Step-by-step explanation:
3.3+10m=7.81
10m = 7.81-3.3
10m = 4.51
m = 4.51/10
m = 0.451

x + -3 + 3 = 5 + 3
x = 5 + 3
(5 + 3 = 8)
x = 8
Answer:

Together, Matthew and Daniel have 67 DVDs. Matthew’s collection has 3 times as many DVDs as Daniel’s collection. Which equation can be used to determine the number of DVDs in Daniel’s collection?
A. 3x - x = 67
B. x + x = 67
C. 3x + x = 67
D. 3x = 67
Answer:
C. 3x + x = 67
Step-by-step explanation:
Means Mathew has 3 units and Daniel has 1 unit.
There's 4 units in total.
4x = 67
3x + x = 67
3x is Mathew's DVDs
x is Daniel's DVDs

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
