A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples.
Is the owner's estimate reasonable?
The owner’s answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with.
The owner’s estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.

Given the similar triangles, find the value of x.
AABC~AAGF
Answer:
x = 4
Step-by-step explanation:
Given that ∆ABC ~ ∆AGF, it follows that their lengths would be proportional to each other. This implies that:
AB/AG = AC/A F
Substitute
55/22 = 30/(4x - 4)
5/2 = 30/(4x - 4)
Cross multiply
5(4x - 4) = 30(2)
20x - 20 = 60
20x - 20 + 20 = 60 + 20
20x = 80
Divide both sides by 20
20x/20 = 80/20
x = 4
An art class is making paperweights out of plaster. They use a mold in the shape of a rectangular prism. (2 1/4m, 2 1/2m, and 1 3/4m represents the size of the prism)
How much plaster will it take to completely fill the mold?
9.84 m³ plaster will it take to completely fill the mold.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Cubic units are used to quantify a solid's volume. For instance, the volume will be given in cubic metres if the dimensions are given in metres. The International System of Units uses this as the reference unit for volume (SI).
We have,
A rectangular prism. (2 1/4m, 2 1/2m, and 1 3/4m represents the size of the prism).
So, the capacity or Volume of mold is
V= l w h
Now, w= 2 1/2 = 5/2 = 2.5 m
and, h=1 3/4 = 7/4 = 1.75 m
and, l= 2 1/4 = 9/4 = 2.25 m
Then, the Volume is
V= 2.5 x 1.75 x 2.25
V = 9.84 m³
Thus, the required volume is 9.84 m³.

How many 1/2 go in 3/4
How many 1/2 go in to 1/4
Answer:
1, 0 or 1, 1/2
Step-by-step explanation:
[tex]\frac{1}{2} = \frac{2}{4}[/tex]
2 goes into 3 once
and doesn't fit into 1
So, [tex]\frac{2}{4}[/tex] goes into [tex]\frac{3}{4}[/tex] once
and it doesn't go into [tex]\frac{1}{4}[/tex]
It could also be 1, 1/2
because half of two can fit into 1
so half of [tex]\frac{2}{4}[/tex] can go into [tex]\frac{1}{4}[/tex]

Answer:
I. The width is 43.5 inches.
II. The length is 24.5 inches.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Perimeter of rectangle = 136 inches
Translating the word problem into an algebraic expression, we have;
L = W - 19 ......equation 1
Perimeter of rectangle = 2(L + W) ......equation 2
To find the dimensions of the rectangle;
136 = 2(L + W)
Substituting eqn 1 into eqn 2, we have;
136 = 2(W - 19 + W)
136 = 2(2W - 19)
136 = 4W - 38
4W = 136 + 38
4W = 174
W = 174/4
W = 43.5 inches
To find the length;
L = W - 19
L = 43.5 - 19
L = 24.5 inches

Which ordered pair would form a proportional relationship with the point graphed below? (60,-20)
Given:
The graphed point is (60,-20).
To find:
The ordered pair that would form a proportional relationship with the given point.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
For the given point,
[tex]k=\dfrac{-20}{60}[/tex]
[tex]k=\dfrac{-1}{3}[/tex]
For option (A),
[tex]k=\dfrac{30}{-10}[/tex]
[tex]k=-3\neq \dfrac{-1}{3}[/tex]
For option (B),
[tex]k=\dfrac{-15}{30}[/tex]
[tex]k=-\dfrac{1}{2}\neq \dfrac{-1}{3}[/tex]
For option (C),
[tex]k=\dfrac{10}{-30}[/tex]
[tex]k=\dfrac{-1}{3}[/tex].
The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.
Therefore, the correct option is C.

12 + x/4 > 20
Thank you if you answer!! please just put the answer
Answer:
The answer is x > 32.
Step-by-step explanation:
1) Subtract 12 from both sides.
[tex] \frac{x}{4} > 20 - 12[/tex]
2) Simplify 20 - 12 to 8.
[tex] \frac{x}{4} > 8[/tex]
3) Multiply both sides by 4.
[tex]x > 8 \times 4[/tex]
4) Simplify 8 × 4 to 32.
[tex]x > 32[/tex]
Therefor, the answer is x > 32.
Find the major intercepts for the ellipse shown below.
A. (0, ±3)
B. (±3, 0)
C. (±2, 0)
The required intercepts of the given ellipse x²/4 + y²/9 = 1 would be (A) (0, ±3).
What are intercepts?A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation intersects the coordinate system's y-axis.
This is done in analytic geometry using the common convention that the horizontal axis represents the variable x and the vertical axis the variable y.
These points satisfy x = 0 because of this.
So, we have the ellipse:
x²/4 + y²/9 = 1
So, the intercepts would accordingly be:
(0, ±3)
Therefore, the required intercepts of the given ellipse x²/4 + y²/9 = 1 would be (A) (0, ±3).

15. Write an equation of a line in standard form that: 2x + 5 passes through the point (1, 5) and is parallel to y=2x+5
Answer:
[tex]y = 2x +3[/tex]
Step-by-step explanation:
Given
Parallel: [tex]y = 2x + 5[/tex]
Passes through (1,5)
Required
Determine the equation
Because it is a parallel to [tex]y = 2x + 5[/tex] then they have the slope.
The slope of [tex]y = 2x + 5[/tex] is 2 i.e. from [tex]y = mx + b[/tex]
So:
[tex]m = 2[/tex]
The line equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 2(x - 1) + 5[/tex]
[tex]y = 2x - 2 + 5[/tex]
[tex]y = 2x +3[/tex]
