Answer:
Step-by-step explanation:
cube means 3D square.. right?
so for volume we want the height x width x length.. make sense?
since each edge is 9'
the volume is [tex]9^{3}[/tex] = 729 [tex]ft^{3}[/tex]
Answer: 729
Step-by-step explanation:
This is very simple all you do is cube 9
[tex]9^{3}\\729[/tex]
Which equation best represents the graph?
Answer:
The third one
Step-by-step explanation:
The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of
x^2 is negative.
So, the answer must be either the first or the third.
It can be seen that when x= -4, y becomes 5.
Substituting the value of x, the third equation gives the value 5.
So, the answer is the third one.
Ernesto has $50 in a savings account that earns 10% interest, compounded annually.
To the nearest cent, how much will he have in 3 years?
Answer:
66.55$

50x.1=5 50+5=55
55x.1=5.5 55+5.5=60.5
60.5x.1=6.05 60.5+6.05=66.55$

Carran is building a fence around his rectangular yard. The fence will cover the front and the 2 sides of the yard. The
front of the yard is 4 feet more than twice the length of one side of the yard. The sides of the yard are the same length. If
the perimeter of the yard is 80 feet, what are the dimensions of the fence?
9514 1404 393
Answer:
sides: 12 feetfront: 28 feetStep-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)
Mrs. Rodriguez assigns 9 more homework problems to
her afternoon class than to her morning class. On
Tuesday, the morning class was assigned 19 homework
problems. Amanda is a student in the afternoon class.
She has already completed 11 homework problems.
How many more problems must she complete?
Answer:
17 problems.
Step-by-step explanation:
19 + 9 = 28
(Amanda is in the afternoon class, so she gets 9 more homework assignments than the morning class, which gets 19.)
28 - 11 = 17
(Amanda has already completed 11 homework problems.)
The square of a number x is 16 more than six times the number
Form an equation in x and solve it.
Answer:
x= 8
Step-by-step explanation:
x^2 = 6x+16
TAKE RHS OVER TO LHS TO EQUATE IT TO 0
x^2 - 6x - 16 = 0
FACTORISE
(x-8)(x+2) =0
Therefore
x-8= 0 or x+2= 0
x= 8 or x= - 2
Sub and see which works
8^2 = 6(8) + 16
64= 64
-2^2 = 6(-2) + 16
-4= 4
So the answer must be
x= 8
Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of the yard not inside the fence?
Answer:
[tex]\angle MKJ = 34[/tex]
Step-by-step explanation:
Given
[tex]\angle LKJ = 124[/tex]
Required
Find [tex]\angle MKJ[/tex]
From the attachment:
The measure of [tex]\angle MKJ[/tex] is calculated using the following expression:
[tex]\angle MKJ + \angle LKM = \angle LKJ[/tex]
Where
[tex]\angle LKM = 90[/tex] -- right-angled.
The expression becomes
[tex]\angle MKJ + 90 = 124[/tex]
[tex]\angle MKJ = 124 - 90[/tex]
[tex]\angle MKJ = 34[/tex]

You guys are Smart, Answer me this. But I need It fast-
Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90
