Answer:
264 cm³
Step-by-step explanation:
Consider the L-shaped end of the figure. It is 7 cm wide, and 3+4 = 7 cm high. It can be considered to be a 7 cm square with a portion cut out of the upper right corner. That portion is a square that is 4 cm by 4 cm.
Then the area of the L-shaped end is ...
(7 cm)(7 cm) -(4 cm)(4 cm) = (49 -16) cm² = 33 cm²
The volume of the figure is the product of this area and the overall length, which is 8 cm.
V = Bh = (33 cm²)(8 cm) = 264 cm³ . . . volume of the figure
_____
Additional comment
There are other ways the volume can be figured. For example, it can be considered as a 7 × 8 × 3 cm block with a 3 × 4 × 8 cm block on top. That gives a volume of ...
V = LWH . . . . for each block
V = (7 cm)(8 cm)(3 cm) +(3 cm)(4 cm)(8 cm) = 168 cm³ +96 cm³ = 264 cm³

Use a coordinate plane to create a rectangular park that has one corner at (−412, 312) and a perimeter of 30 units. Label the coordinates of each corner of the park. Then plot points with mixed number coordinates inside the park to represent a swing set, a slide, and a bench. Plot the slide farthest from the x-axis and the bench closest to the x-axis. What are the coordinates of the points you plotted?
A rectangle has four sides, where the opposite sides are equal
The possible coordinates are: (-4.5, 3.5), (-4.5,10.5), (3.5,3.5) and (3.5,10.5)
The coordinate point is given as:
[tex]\mathbf{(x,y) = (-4\frac12,3\frac12)}[/tex]
Express as decimal
[tex]\mathbf{(x,y) = (-4.5,3.5)}[/tex]
The perimeter is said to be 30 units.
So, we have:
[tex]\mathbf{P = 2(L + W)}[/tex]
This gives
[tex]\mathbf{2(L + W) = 30}[/tex]
Divide through by 2
[tex]\mathbf{L + W = 15}[/tex]
This means that the sum of the dimensions is 15 units.
So, we can assume that:
Length = 8
Width = 7
So, the other coordinates are calculated as follows:
[tex]\mathbf{(x,y) = (-4.5,3.5+7) = (-4.5,10.5)}[/tex]
[tex]\mathbf{(x,y) = (-4.5 + 8,3.5) = (3.5,3.5)}[/tex]
[tex]\mathbf{(x,y) = (-4.5+8,3.5+7) = (3.5,10.5)}[/tex]
So, the possible coordinates are: (-4.5, 3.5), (-4.5,10.5), (3.5,3.5) and (3.5,10.5)

Answer:
Step-by-step explanation:
1) x +y = 3
Subtract 'x' from both sides
y = -x + 3
2) x - 3y = 12
Subtract 'x' form both sides.
-3y = -x + 12
Divide the entire equation by (-3)
[tex]\dfrac{-3y}{-3}=\dfrac{-x}{-3}+\dfrac{12}{-3}\\\\\\y = \dfrac{1}{3}x-4[/tex]
3) 5x + 2y = 10
Subtract 5x from both sides
2y = -5x + 10
Divide the entire equation by 2
[tex]\dfrac{2y}{2}=\dfrac{-5x}{2}+\dfrac{10}{2}\\\\\\y = \dfrac{-5}{2}x + 5[/tex]
4) y = 6x + (1/3)
It is already in y =mx +b form
5)
[tex]y=\dfrac{1}{x}*x-15\\\\\\y = 1-15\\\\y = -14\\\\y=0x -14[/tex]
Which statement correctly uses ratio language to describe a part-to-whole ratio of 7:10?
How can we get Equation B from Equation A?
A. 2x−1=5x
b. −1=3x
Question 2 options:
Rewrite one side (or both) using the distributive property
Add/subtract a quantity to/from only one side
Add/subtract the same quantity to/from both sides
Rewrite one side (or both) by combining like terms
Answer:
-1 = 5x - 2x
Step-by-step explanation:
When 2x will go to the other side of the equal sign, it will become negative.
5x - 2x will become 3x
From here you will get Equation B
2x - 1 = 5x
-1 = 5x - 2x
-1 = 3x

M=-1, b=2 write an equation of a line with the given slope m and y- intercept b
Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = - 1 and b = 2 , then
y = - x + 2 ← equation of line

Answer:
w = [tex]\frac{t}{4}[/tex]
Step-by-step explanation:
We have t = 4w, the question is asking to rearrange the equation to make "w" the subject, meaning that we have to isolate the variable w.
When we have a number (usually known as a coefficient) next to a variable and want to get rid of it, we need to divide it by both sides. Therefore :
t = 4w
[tex]\frac{t}{4} =\frac{4w}{4}[/tex]
[[tex]\frac{t}{4} =w[/tex]]
Since "t" is an undefined variable and has no initial value, you cannot divide it by anything, therefore it'll stay as [t/4 = w]

If the radius of a right circular cylinder is doubled and height becomes 1/4 of the original height, then find the ratio of the curved surface areas of the new cylinder to that of the original cylinder.
Given info:-If the radius of a right circular cylinder is doubled and height becomes 1/4 of the original height.
Find the ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder ?
Explanation:-
Let the radius of the right circular cylinder be r units
Let the radius of the right circular cylinder be h units
Curved Surface Area of the original right circular cylinder = 2πrh sq.units ----(i)
If the radius of the right circular cylinder is doubled then the radius of the new cylinder = 2r units
The height of the new right circular cylinder
= (1/4)×h units
⇛ h/4 units
Curved Surface Area of the new cylinder
= 2π(2r)(h/4) sq.units
⇛ 4πrh/4 sq.units
⇛ πrh sq.units --------(ii)
The ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder
⇛ πrh : 2πrh
⇛ πrh / 2πrh
⇛ 1/2
⇛ 1:2
Therefore the ratio = 1:2
The ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder is 1:2
The temperature at Violet's house is set at 76 degrees Fahrenheit but might vary as much as 5 degrees. Write an inequality to represent this situation.
The inequality to represent this situation is |x - 76| < 5.
The temperature of her house is set at 76° Fahrenheit. The temperature might vary at 5 degrees. This simply means the temperature might increase by 5 degrees or decrease by 5 degrees.
Therefore, the inequality to represent this situation can be represented below:
|x - 76| < 5
-5 < x -76 < 5
add 76
-5 + 76 < x -76 + 76 < 5 + 76
71 < x < 81
Therefore, the inequality to represent this situation is |x - 76| < 5.

Answer:
$4127
Step-by-step explanation:
The amortization formula is good for finding this value.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where P is the amount invested at rate r for t years.
A = $600,000(0.055/12)/(1 -(1 +0.055/12)^(-12·20)) = $4127.32
You will be able to withdraw $4127 monthly for 20 years.
