A shopkeeper has corn flour and wheat flour. The ratio of the weight of the corn flour to the weight of the wheat flour is 3 : 5. The weight of the corn flour is 21 pounds. What is the weight of the wheat flour?
Answer:
35 pounds
Step-by-step explanation:
To solve this, we can set up a proportion.
Let's name the weight of the wheat flour "x."
3/5=21/x
Cross multiply to solve.
3*x=5*21
3x=105
x=35
The weight of the wheat flour is 35 pounds.

Answer:
12a. (-6, -6)
12b. 17
13a. y = [tex]\frac{-1}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
13b. 2
Step-by-step explanation:
12a. Using the midpoint formula:
[tex](\frac{-9-3}{2} ,\frac{2-14}{2} )[/tex] = [tex](\frac{-12}{2} , \frac{-12}{2})[/tex] = (-6, -6)
12b. Using the Distance formula:
d = [tex]\sqrt{(3 - (-9))^{2} +( 14 - 2)^{2} }[/tex] = [tex]\sqrt{(12)^{2}+(12)^{2} }[/tex] = [tex]\sqrt{144 + 144}[/tex] = [tex]\sqrt{288}[/tex]
= 12[tex]\sqrt{2}[/tex] or 17
13a. x + 2y = 3
2y = 3 - x
y = [tex]\frac{-1}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
13b. The perpendicular slope is 2
What is the median of the following set of data?
0.6, 0.5, 0.9, 0.4, 0.3, 0.7, 0.2
Answer:
Median: 0.5
Step-by-step explanation:
Arrange the following set of data from least to greatest:
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9
then find the middle number (the median).
since there are seven numbers in the data set we divide it, by doing this:
{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}
Therefore, the median for the data set is 0.5!

There are 90 penguins in a zoo. There are two types - Humboldt and Emperor.
52 are female, of these 6 are Emperor penguins.
There are 5 male Emperor penguins.
Use this information to complete the frequency tree.
Humboldt penguins
Emperor penguins
Male
Female
Humboldt penguins
Emperor penguins
Answer:
See below.
Step-by-step explanation:
Humboldt penguins; 90 - (5 + 6) = 79.
Emperor penguins: 5 + 6 = 11.
Total Male: 90 - 52 = 38.
Male Humboldt penguins: 38 - 5 = 33.
Total Female: 52.
Female Humboldt penguins: 52 - 6 = 46.
We can solve this by creating an attribute table.

A cardboard box is 18 feet long, 7 feet wide, and 6 inches high. What is the is closest to the volume of the box in cubic YARDS? 20 points
Answer:
The volume of the box is [tex]2.33\ \text{yards}^3[/tex].
Step-by-step explanation:
We have,
Length of a cardboard box is 18 feet
Width of cardboard box is 7 feet
Height of a cardboard box is 6 inches
The conversion from one units and another is as follows :
1 foot = 0.334 yards
18 feet = 6 yards
7 feet = 2.334 yards
1 inch = 0.0277 yards
6 inches = 0.1667 yards
Now,
Length, l = 6 yards
Width, b = 2.334 yards
Height, h = 0.1667 yards
The box in the form of cuboid. The volume of a cuboid shaped object is given by :
[tex]V=l\times b\times h[/tex]
Plugging all the values, we get :
[tex]V=6\times 2.334\times 0.1667\\\\V=2.33\ \text{yards}^3[/tex]
So, the volume of the box is [tex]2.33\ \text{yards}^3[/tex].

please answer with the:
axis of symmetry
vertex
(explain how if you can)
Answer:
x=1
Step-by-step explanation:
X= means that it is the vertical line on that number, so x=1 would be the vertical lines going through 1, which would be in the middle of the parabola, thus having symmetry
Answer:
axis of symmetry: x = 1
vertex: (1,-4)
Step-by-step explanation:
You can find the axis of symmetry for this parabola by looking at the x coordinate for the vertex or buy looking at the graph for which x value that you can draw a line through and have symmetry on both sides.
For the vertex, you just look for the maximum of minimum (for this graph its minimum) point on the parabola.

do all % please
if u get them right i need help with more
Answer50% = 12.5
Step-by-step explanation:
Answer:
Im too lazy to put here
Step-by-step explanation:
10% off --> 90% the actual cost
25 x 90% = 22.50
$22.50
20% off --> 80% the actual cost
25 x 80% = 20.00
$20.00
30% off --> 70% the actual cost
25 x 70% = 17.50
$17.50
40% off --> 60% the actual cost
25 x 60% = 15.00
$15.00
50% off --> 50% the actual cost
25 x 50% = 12.50
$12.50
A cube with a side length of 6 feet is sliced diagonally such that it passes through the three vertices shown in the figure. Which describes the cross section?
A cube. A cross section is a triangle that touches 3 corners of the cube.
a triangle with 3 equal sides measuring 6 feet
a triangle with 3 equal sides measuring greater than 6 feet
a triangle with only 2 equal sides measuring 6 feet
a triangle with only 2 equal sides measuring greater than 6 feet
Answer:
C) a ttiangle with only 2 sides measuring 6 feet
Step-by-step explanation:
The cross section is a triangle with three equal sides measuring more than 6 feet.
What is a cube?A cube is a solid three dimensional shape with 6 faces or squares of equal length.
Analysis:
The diagonal of one face of the cube forms right angle triangle with the adjacent sides of that face of the cube.
So using Pythagoras to find length,
[tex]diagonal^{2}[/tex] = [tex]6^{2}[/tex] + [tex]6^{2}[/tex]
[tex]diagonal^{2}[/tex] = 36 + 36
[tex]diagonal^{2}[/tex] = 72
diagonal = [tex]\sqrt{72}[/tex] = 8.48 feet. Which is same form the remaining two diagonals forming the triangle.
Therefore the cross section is a triangle with three equal sides with length greater than 6 feet.
In conclusion, the cross section is a triangle with three equal sides with length greater than 6 feet.

Whats the answers for questions 3
Answer:
?
Step-by-step explanation:
Choose the system of equations that matches the following graph:
3x + 4y = 24
3x + y = −3
3x + 4y = 24
3x − y = 3
3x − 4y = −24
3x + y = −3
3x − 4y = −24
3x − y = 3
One of the lines passes through points (0, 6) and (-4, 3). Hence the equation is given by:
(y - 6)/(x - 0) = (3 - 6)/(-4 - 0)
(y - 6)/x = -3/-4 = 3/4
4(y - 6) = 3x
4y - 24 = 3x
3x - 4y = -24
The other line passes through points (0, -3) and (1, 0). Hence the equation is given by:
(y - (-3))/(x - 0) = (0 - (-3))/(1 - 0)
(y + 3)/x = (0 + 3)/1
y + 3 = 3x
3x - y = 3
Therefore, the system of equations representing the graph is:
3x - 4y = -24
3x - y = 3

Answer:
63$...I think
Step-by-step explanation:
if there was 5 friends and each paid 14$ the total must have been 70$. However, since the soda was 7$, then if you take away 7$ from the total, then the chicken must have been 63$
I don't know, man. Math isn't really my strongest suit, but I hope this helps :D
Answer:
$77
Step-by-step explanation:
Each person paid $14
Aiden+5 friends= 6 people
$14×6= $84
total cost of soda was $7
$84-$7= $77
The figure above the x-axis is the preimage. The figure below the x-axis is the image. Which transformation produced the image?
A.
reflection across the x-axis
В.
reflection about the origin
C.
rotation 90° clockwise about the origin
D.
rotation 90° counterclockwise about the origin
Answer:
Option B.
Step-by-step explanation:
From the picture attached, figure above the x-axis is the pre-image and below the axis is the image.
Let's choose a point B of the image having coordinates (0, 2).
When the point B is transformed, coordinates of the point B' is (0, -2)
And the rule for this transformation will be,
(x, y) → (-x, -y)
This rule shows the reflection of pre-image over the origin.
Option (B). will be the answer.
Answer:
B
