If Janet has 5 yards of fabric that is 2 1/4 feet wide, and she used 1/3 of it to make one kind of curtains, and the rest to make another kind, what is the area of the fabric she used for the first kind of curtains?
11 1/4
Step-by-step explanation:
the yards have to be converted to feet
1 yards = 3 feet
5 yards x 3 = 15 feet
Area of a rectangle = length x width
15 x 2 1/4
15 x 9/4 = 33 3/4
33 3/4 x 1/3 = 135 /12 = 11 1/4

Given:
The figure of a triangle LMN.
P is the centroid of triangle LMN.
To find:
14. Find the value of PN if QN=30.
15. Find the value of PN if QN=9.
Solution:
We know that the centroid in the intersection of medians of a triangle and centroid divides each median in 2:1.
Since P is the centroid it means NQ is the median from vertex N. It means P divides the median NQ in 2:1. So, PN:PQ=2:1.
14. We have QN=30.
[tex]PN=\dfrac{2}{2+1}QN[/tex]
[tex]PN=\dfrac{2}{3}(30)[/tex]
[tex]PN=2(10)[/tex]
[tex]PN=20[/tex]
Therefore, the value of PN is 20 when QN=30.
15. We have QN=9.
[tex]PN=\dfrac{2}{2+1}QN[/tex]
[tex]PN=\dfrac{2}{3}(9)[/tex]
[tex]PN=2(3)[/tex]
[tex]PN=6[/tex]
Therefore, the value of PN is 6 when QN=9.

Answer:
15u + 141 = 420
Step-by-step explanation:
So basically we are modelling how much the coach is spending. Each player is given a uniform and a basketball
We can use 'u' as the cost of a single uniform
We can use 'b' as the cost of a single basketball
Since there is 15 players we must give a ball and uniform to each so
15u + 15b = 420
The problem gives us the cost of each basketball: 9.40
so now 15u + 15(9.4) = 420
15u + 141 = 420
Solve the equation for all real solutions.

Shelby earns $8 an hour babysitting. How many hours must she babysit to earn enough to buy a bicycle that costs $176?
Answer:
Number of hours= 22
Step-by-step explanation:
Giving the following information:
Hourly rate= $8
Cost of the bycicle= $176
To calculate the number of hours to be worked, we need to use the following formula:
Number of hours= total cost / hourly rate
Number of hours= 176 / 8
Number of hours= 22 hours
Suppose a 250-brick set of Braille Bricks includes 50 pieces of each of five colors: red, yellow, green, blue and orange. If Kevin chooses one piece of lego at random, what is the probability that he chooses a red or a yellow piece? Write your answer in simplest fraction form.
Answer: 2/5
Step-by-step explanation:
Number of red bricks = 50
Number of yellow bricks = 50
Number of green bricks = 50
Number of blue bricks = 50
Number of orange bricks = 50
Total number of bricks = 250
The probability of choosing a red piece is 50/250 = 1/5. Also, the probability of choosing a yellow piece is also 1/5.
Therefore, the probability that he chooses a red or a yellow piece will be:
= P(red) + P(yellow)
= 1/5 + 1/5
= 2/5
Find the slope of the line.
(0,2) (2,-2)

The slope is 4/2 and you simplify it inti 2. And since the line is going down, it’s a negative slope, so the answer will be -2.
Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
2, 10, 18, ...
Answer:
Arithmetic sequence; common difference is 8.
Step-by-step explanation:
An arithmetic sequence increases or decreases by a fixed amount from term-to-term.
10 - 2 = 8
18 - 10 = 8
The next term will be 18 + 8 = 26, and so on.
Find the 9th term of the geometric sequence whose common ratio is
2.
and whose first term is 7.

On a coordinate plane, the location of 3 points are: (0, 6). (5. -4), and (-1-5). Where would the fourth point need to be located in order to form a parallelogram?
Given:
The three vertices of parallelogram are (0,6),(5,-4),(-1,-5).
To find:
The fourth vertex of the parallelogram.
Solution:
Consider the given vertices of parallelogram are A(0,6), B(5,-4), C(-1,-5).
Let the fourth vertex be D(a,b).
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
We know that the diagonal of parallelogram bisect each other. It means their midpoints are same.
Midpoint of AC = Midpoint of BD
[tex]\left(\dfrac{0+(-1)}{2},\dfrac{6+(-5)}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]
[tex]\left(\dfrac{-1}{2},\dfrac{1}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{5+a}{2}=-\dfrac{1}{2}[/tex]
[tex]5+a=-1[/tex]
[tex]a=-1-5[/tex]
[tex]a=-6[/tex]
And,
[tex]\dfrac{-4+b}{2}=\dfrac{1}{2}[/tex]
[tex]-4+b=1[/tex]
[tex]b=1+4[/tex]
[tex]b=5[/tex]
Therefore, the coordinates of fourth vertex are (-6,5).

find the value of x by finishing solving the equation shown below
Answer:
Final answer is x = -2
Step-by-step explanation:
-6x-3=9
add 3 to -3 and to 9 (we add 3 because its a negative)
9+3 becomes 12.
now we are left with -6x=12
divide on both sides, -6x divided by -6, and 12 divided by -6.
this leaves us with -2.
x= -2

Step-by-step explanation:
The area of the figure which is composite of rectangle and triangle is 42.5 square meters
What is Area of Rectangle?The area of Rectangle is length times of width.
Let us find the area of rectangle whose length is 7 m and width is 5 m
Area of rectangle =7×5
=35 square meters
Now we observe the figure there is right triangle whose base is 3m and height is 5m
Area = 1/2×3×5
=7.5 square meters
Total area is sum of rectangle area and triangle area
Total area = 35+7.5
=42.5 square meters
Hence, the area of the figure which is composite of rectangle and triangle is 42.5 square meters

Answer:
480 inches^3
Step-by-step explanation:
The volume of a Prism is: Bh
B= length of the base
h= height of the lateral face
(8*10)4
320 inches^3
So for the 2nd figure on top you do the same.
This time you divide by 2.
So it's 160 inches^3.
Add up you get a sum of 48- inches^3.
