A fruit vendor purchased 540 fruits in all for $150. He sold 15 dozens at 2 bananas a dollar, another 15 dozens at 3 bananas a
dollar and the remaining at 5 bananas a dollar. Find his loss or gain percentage. ( with explanation )
Answer:
First find how much bananas are in a dozen
15 x 12 = 180
Divide the amount by the amount of bananas per dollar to find profit
180 / 2 = $90
Do the same thing as before
15 x 12 = 180
180 / 3 = $60
Find how many bananas are left
180 + 180 = 360
540 - 360 = 180
Do the same as before
180 / 5 = $36
Add up all the money. 90 + 60 + 36 = 186
Subtract the cost
185 - 150 = 36
To find percentage increase
36 / 150 = 0.24 or 24% profit
Hope this helps

How are the following three expressions different from each other, if needed they are? Do not just state the value of each but explain what may be same or different.
That what my teacher said I’m confused plz help
Thank u so much to the people who helped me answer it.
Answer:
2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.
Step-by-step explanation:
We are given the three expressions different from each other
We are supposed to find what may be same or different.
1) [tex](-2)^2[/tex]
[tex]\Rightarrow (-1)^2 \times (2)^2\\\Rightarrow -1 \times -1 \times 2 \times 2 \\\Rightarrow 4[/tex]
2)[tex]-2^2[/tex]
[tex]\Rightarrow -1 \times 2^2\\\Rightarrow -1 \times 2 \times 2 \\\Rightarrow -4[/tex]
3)[tex]-(2)^2[/tex]
[tex]\Rightarrow -1 \times (2)^2\\\Rightarrow -1 \times 2 \times 2 \\\Rightarrow -4[/tex]
Now 2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.

3x-2≤5(x+2)
Distribute
3x-2≤5x+10
Subtract 3x
3x-2-3x≤5x +10-3x
-2 ≤2x+10
Subtract 10 from each side
-2-10 ≤2x+10-10
-12 ≤2x
Divide by 2
-12/2≤2x/2
-6 ≤x
Answer:
Step-by-step explanation:
You have to first use the distributive property of 5(x+2)
That would be 5x+10.
So it would be all together
[tex]3x-2\leq 5x+2[/tex]
to see if it is true
x=2
6-2
[tex]6-2\leq 10+2\\4\leq 12[/tex]
it is true

Answer:
Step-by-step explanation:
1). Segment AB = [tex]\overline{AB}[/tex] (Option D)
Segments are represented by an over-line/bar on the segment.
2). Length of segment AB = AB (Option B)
3). MN = 7 (Option C)
Since the measure of segments MN and KL are equal from the figure attached.
4). [tex]\overline{KL}[/tex] is congruent to [tex]\overline{MN}[/tex]
Given in the figure attached.
Answer:
1) Segment AB =d
2) Length of segment AB = b
3)MN=c
4) [tex]\widehat{KL}[/tex] is congruent to = a
Step-by-step explanation:
We are supposed to match the items
Options:
a.[tex]\widehat{MN}[/tex]
b. AB
C. 7
d. [tex]\widehat{AB}[/tex]
1) Segment AB
So, D option denotes the segment
So, 1) Segment AB = [tex]\widehat{AB}[/tex]
2) Length of segment AB = Option b
So, Length of segment AB =AB
4) [tex]\widehat{KL}[/tex] is congruent to
So, referring the given figure we can say
[tex]\widehat{KL}[/tex] is congruent to [tex]\widehat{MN}[/tex]
So, [tex]\widehat{KL}[/tex] is congruent to option a
3)MN
Since [tex]\widehat{KL}[/tex] is congruent to [tex]\widehat{MN}[/tex](by 4)
So, KL = MN = 7
So, MN = 7
So, MN = option c

Step-by-step explanation:
using SOH CAH TOA, solve for x.
Answer:
x=10.93 or 10.9
Step-by-step explanation:
To find x we use sin
sin(40) = 0.6427876097 then * 17
= 10.9273
= 11
We can check and plug in answer as inverse to find other side
11/sin (40degree) x (90 degree) = 17.11
If we plug in the original 10.9273 we actually find 17
So we should show the correct amount 10.9273 and if rounding try 10.93
10.93/sin (40 degree) x sin (90 degree) = 17.00
A line passes through the point (–7, 5) and has a slope of One-half. Which is another point that the line passes through?
A. (–13, 9)
B. (–9, 13)
C. (9, 13)
D. (13, 9)
Answer:
C. (9, 13)
Step-by-step explanation:
y = mx + b
y = (1/2)x + b
(-7, 5)
5 = (1/2)*(-7) + b
5 = - 7/2 + b
b = 5+ 7/2 = 10/2 + 7/2 = 17/2
y = (1/2)x + 17/2
C. (9, 13)
13 = (1/2)*9 + 17/2
13 = 26/2
13=13 True
Answer:
It is C (9,13)

According to the water surface area rule, a fish tank can be
stocked with one inch of fish for each twelve square inches of
surface area. The fish that you are interested in putting in your
fish tank are each 2 inches. Your fish tank has a surface area of
576 square inches. According to the water surface area rule,
what is the maximum number of fish you can put in your tank?
Answer:
24 fishes
Step-by-step explanation:
If for 1 inch of fish corresponds 12 square inches of surface area, then for 2 inches correspond 24 square inches. Given that each fish is 2 inches, then for 1 fish 24 square inches of surface area is needed. To know how many fish you can put in your tank, we need to solve the following proportion:
1 fish / x fish = 24 square inches / 576 square inches
x = 576/24
x = 24 fishes

A rectangular bathtub has a depth of 24 in., a width of 24 in., and a length of 60 in. If the tub is filled up to
3 inches below the top, how much water is in the tub?
Answer:
The amount of water is [tex]30,240in^3[/tex]Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a rectangular prism in the form of a bathtub.
Given data
depth of bathtub= 24 in
width of bathtub= 24 in
length of bathtub= 60 in
the volume of water in the bathtub is a function of the depth of water in relation with the dimension of the bathtub.
the depth of water is 3 in below the the top
hence the depth of water (24 in- 3 in)= 21 in
the expression for the volume of water is given as
[tex]volume= length* width*depth\\volume= 60*24*21=30,240in^3[/tex]
The relationship between the number of pounds (lb) of peppers and the
total cost in dollars is shown in the graph. What is the unit price of
peppers?
(Brainly this isn't a quiz for me so don't at me)
Explanation:
The unit price is the price of 1 unit, in this case one pound. So we locate x = 1 on the x axis, draw a vertical line upward til we get to the diagonal line, and then draw a horizontal line until we reach the y axis. You should arrive at y = 3.
Answer:
3$/1lb

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y– 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Answer:
[tex]y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex].
Step-by-step explanation:
If a line passing through two points, then the equation of line is
[tex](y-y_1)=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It is given that the passing through (1,3) and (-9,-2). So, equation of line in point slope form is
[tex]\Rightarrow (y-3)=\dfrac{-2-3}{-9-1}(x-1)[/tex]
[tex]\Rightarrow (y-3)=\dfrac{1}{2}(x-1)[/tex]
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
Now,
[tex](y-3)=\dfrac{1}{2}(x-1)[/tex]
[tex]\Rightarrow (y-3)=\dfrac{1}{2}(x}-\dfrac{1}{2}(1)[/tex]
[tex]\Rightarrow y=\dfrac{1}{2}(x}-\dfrac{1}{2}+3[/tex]
[tex]\Rightarrow y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex]
Therefore, the required equation is [tex]y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex].
Answer:
The Answer is C
Step-by-step explanation:
i think This is correct
what’s the best answer ???
Answer:
Option A
Step-by-step explanation:
Slope is: [tex]m=\frac{\text{Rise}}{\text{Run}} =\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (-4,3) and (3,1).
[tex]m=\frac{1-3}{3-(-4)}=\frac{-2}{7} =\boxed{-\frac{2}{7}}[/tex]
Option A should be the correct answer.
Please help me! I'm terrible at math
Answer:
(3.) x = 45
Step-by-step explanation:
Because the lines are parallel and cut by the same line, the angles within are equal as well.
Which means that...
Angle GE = Angle EFD
Therefore (2x-30) = (x + 15)
2x - 30 = x + 15
+30 +30 (add 30 to both sides to get rid of the -30)
2x = x + 45
-x -x (subtract x from both sides to get rid of the single positive x)
x = 45

Answer:
$997
Step-by-step explanation:
Base Salary: $150 (given)
Additional information on everything he sells: 14%
He sells $6050.00 last week, so then his commision would be 14% of the $6050.
x = 150 + ( 0.14 x 6050 )
OR
14/100 x 6050
would equal: $847
Total pay for last week would equal base salary and the additional pay.
$150 + $847
= $997
His total pay for last week would equal $997.
