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.

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.

Answer:
(0,-9), x = 0, (-3,0), (3,0), domain, -9
Step-by-step explanation:
Complete the square and you can read everything off the equation,
y = x^2 - 9
= (x - 0)^2 - 9
Vertex : (0,-9)
Axis of symmetry: x = 0
x-intercepts: x^2 = 9 -> x = ±3
Left x-intercept: (-3,0)
right x-intercept: (3,0)
Since the function is well-defined for any x-values,
we can say that its domain is the set of all real numbers.
Since the minimum point of the graph is (0,-9),
The range will be greater than or equal to -9.
Answer:
-
Step-by-step explanation:
-
How do I solve this problem?
6x + 9 <7x
Answer:
x > 9
Step-by-step explanation:
6x + 9 < 7x .
-6x -6x <---- Subtract 6x from both sides.
9 < x <----- 7x - 6x = 1x (which can also be written as just x)
Therefore the answer is x > 9.

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 equation represents a line that passes through (2, -1) and has a slope of 3?A) y- 2 = 3(x + 1/2)
B) y- 3 = 2(x + 1/2)
C) y+ 1/2= 3(x - 2)
D) y+ 1/2= 2(x - 3)
Given:
The slope of the line is 3.
The line passes through the point (2,-1).
To find:
The equation of the line.
Solution:
Point slope form of a line: If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (2,-1) with slope 3. So, the equation of the line is
[tex]y-(-1)=3(x-2)[/tex]
[tex]y+1=3(x-2)[/tex]
Therefore, the required equation is [tex]y+1=3(x-2)[/tex]. Hence, all the options are incorrect.
