Answer:
First number is x
Second number is y
Step-by-step explanation:
x = 2y + 1
x + y = 25
(2y + 1) + y = 25
3y = 24
y=24/3
y = 8
x = 2(8) + 1
x = 16+1
x=17

In how many ways can 3 red balls , 4 blue balls and
5 white balls be selected from 5 red balls, 5 blue
balls and 7 white balls ?
Answer:
1050 ways
Step-by-step explanation:
Total Number of red balls = 5
Total Number of blue balls = 5
Total Number of white balls = 7
Number of red balls selected = 3
Number of blue balls selected = 4
Number of red balls selected = 5
Using the multiplication and combination relation :
nCr * nCr * nCr
Red balls = 5C3
Blue balls = 5C4
White balls = 7C5
Using calculator:
5C3 * 5C4 * 7C5 = 10 * 5 * 21
(10 * 5 * 21) = 1050 ways
Christina is making a necklace using beads. She has 20 red, 14 blue, 10 purple, 28 green, and 8 yellow beads. She randomly chooses a bead to start the necklace. What is the probability of Christina choosing a pink bead?
Answer:
0.
Step-by-step explanation:
There is a total of 20 red + 14 blue + 10 purple + 28 green + 8 yellow beads which equal 80 total beads. However, she does not have any pink beads, so the probability of picking one is 0 pink beads / 80 total beads = 0.

What is the mean of the following data set: 100, 121, 105, 113, 108
Answer:
Mean = 109.4
Step-by-step explanation:
Mean = (Sum of all values)/(Number of values)
Mean = (100 + 121 + 105 + 113 + 108)/(5)
Mean = (547)/5
Mean = 109.4
Answer:
109
Step-by-step explanation:
Mean is just finding the average of the data set.
100+121+105+113+108=547, first add up all the numbers
547/5=109.4, then divide that sum by the amount of numbers in the set

Answer:
(x - 3)(x - 12)
Step-by-step explanation:
Assuming you require to factor the expression
x² - 15x + 36
Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (- 15)
The factors are - 3 and - 12, since
- 3 × - 12 = + 36 and - 3 - 12 = - 15 , then
x² - 15x + 36 = (x - 3)(x - 12) ← in factored form

Answer: 6 1/8
Step-by-step explanation:
Each x on the line represents one piece of string that long. For example, since there is one x at 1/8, she cut one piece of string 1/8 ft long. So you take all the values and add them up:
1/8+2/4+2/4+2/4+2/4+5/8+3/4+3/4+7/8
then find a common denominator (so make everything over 8)
1/8+4/8+4/8+4/8+4/8+5/8+6/8+6/8+7/8 = 41/8
when you divide this, you will get 5 1/8
since theoriginal problem says she still has 1 foot leftover, you add one to get the total value when she started.
So, Emma had 6 1/8 ft string originally

48 boxes are loaded onto a truck. The still need to load 96% of the boxes onto the truck. What is the total number of boxes being loaded
Answer:
the total number of boxes being loaded is 1,200 trucks
Step-by-step explanation:
Given that
There are 48 boxes that should be loaded onto a truck
And, still it is required to lead 96% of the boxes onto the truck
We need to find out the total number of boxes that should be loaded
So
Since 48 boxes represent the 4% of the boxes that are loaded
So,
The total number of boxes would be
= 48 × 100 ÷ 0.04
= 1,200 trucks
Hence, the total number of boxes being loaded is 1,200 trucks

The line 3x-8y=k cuts the x-axis and y- axis at the point A and B respectively. If the area of ∆AOB =12sq.units, find the value of k.
Given:
The equation is:
[tex]3x-8y=k[/tex]
It cuts the x-axis and y- axis at the point A and B respectively.
The area of ∆AOB =12 sq.units.
To find:
The value of k.
Solution:
We have,
[tex]3x-8y=k[/tex]
Substituting [tex]x=0[/tex] to find the y-intercept.
[tex]3(0)-8y=k[/tex]
[tex]0-8y=k[/tex]
[tex]y=\dfrac{k}{-8}[/tex]
[tex]y=-\dfrac{k}{8}[/tex]
Substituting [tex]y=0[/tex] to find the x-intercept.
[tex]3x-8(0)=k[/tex]
[tex]3x-0=k[/tex]
[tex]x=\dfrac{k}{3}[/tex]
Area of a triangle is:
[tex]A=\dfrac{1}{2}\times base\times height[/tex]
The height of the ∆AOB is [tex]OB=\dfrac{k}{8}[/tex] because distance cannot be negative and the base of the ∆AOB is [tex]OA=\dfrac{k}{3}[/tex]. So, the area of the ∆AOB is:
[tex]A=\dfrac{1}{2}\times \dfrac{k}{8}\times \dfrac{k}{3}[/tex]
[tex]A=\dfrac{k^2}{48}[/tex]
It is given that, the area of ∆AOB = 12 sq.units.
[tex]\dfrac{k^2}{48}=12[/tex]
[tex]k^2=576[/tex]
[tex]k=\pm \sqrt{576}[/tex]
[tex]k=\pm 24[/tex]
Therefore, the value of k is either 24 or -24.

PLEASE HELP DUE IN 10 MINS
Answer:
x = 8
Step-by-step explanation:
The measures of the angles in a triangle add up to equal 180°
That being said we can create an equation to solve for x
( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )
180 = 90 + 5x + 5 + 5x + 5
now we solve for x using basic algebra
step 1 combine like terms
90 + 5 + 5 = 100
5x + 5x = 10
now we have 180 = 100 + 10x
step 2 subtract 100 from each side
180 - 100 = 80
100 - 100 cancels out
now we have 10x = 80
step 3 divide each side by 10
10x / 10 = x
80 / 10 = 8
we're left with x = 8
How do i do this? With steps pleaseeeeeeeeeee thank youuu
Answer:
110°
Step-by-step explanation:
Since angle B is 30° and the ratio of a to b is 2:1, multiply 30 by 2 to get the measure of angle a = 60°.
Since angles a is 60° And the ratio of a to c is 3:1, divide 60 by 3 to get the measure of angle c = 20°.
add them up:
60 + 30 + 20 = 110°

Answer:
56.25 π cm^2
Step-by-step explanation:
The circumference of a circle is given by C = 2 π r
15 π = 2 π r
Divide each side by π
15 = 2r
Divide by 2
15/2 = 2r/2
7.5 = r
We want to find tha area
A = π r^2
A = π (7.5)^2
A = π 56.25
A = 56.25 π

AThe formula for the area of a trapezoid treats the distance between the parallel sides as the height. Doing this lists the height as 4m.
BYou can separate a trapezoid into a rectangle with a width of 3 and a height of 4, as well as a right triangle with a width of 2 and a height of 4.
CThis expression is the written out portion of separating the trapezoid into a triangle and rectangle.
(3 * 4) represents the rectangle and (1/2 * 2 * 4) represents the triangle.
DThe area as found by the accurate expression in part C is 16.

Find the volume of the given prism. Round to the nearest tenth if necessary.
1 m
34
8.5 m
17 m
Question 2 (4 points)
Given:
The base of the prism is a right triangle with legs 1 m and 2 m.
The height of the prism is 17 m.
To find:
The volume of the given prism.
Solution:
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
So, the area of base of the prism is:
[tex]Area=\dfrac{1}{2}\times 1\times 2[/tex]
[tex]Area=1[/tex]
Now, the volume of the prism is:
[tex]V=Bh[/tex]
Where, B is the base area and h is the height of the prism.
Substituting [tex]B=1,h=17[/tex], we get
[tex]V=(1)(17)[/tex]
[tex]V=17[/tex]
The volume of the prism is 17 cubic m. Therefore, the correct option is (d).
A wheelbarrow has one wheel and a wagon has 4 wheels. Each day, a company has 160 wheels which makes 70 garden vehicles. How many of each vehicle can the company make?
Answer:
x = number of wheelbarrow = 40
y = number of wagon = 30
Step-by-step explanation:
Let
x = number of wheelbarrow
y = number of wagon
x + y = 70 (1)
x + 4y = 160 (2)
subtract (1) from (2) to eliminate variable x
4y - y = 160 - 70
3y = 90
y = 90/3
y =30
Substitute y = 30 into (1)
x + y = 70 (1)
x + 30 = 70
x = 70 - 30
x = 40
x = number of wheelbarrow = 40
y = number of wagon = 30
