Answer:
P(B and V)=10%
Step-by-step explanation:To solve this poroblema we use the formula of combinations:
C(n,r)=(nr)=n!(r!(n−r)!)
Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:
5C2= [tex]\frac{5!}{2!(5-2)!}[/tex]
5C2=10
The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:
2C2=1
Then the probability is:
P( B and V)= [tex]\frac{1}{10}[/tex]
=0.1= 10%
[tex]\frac{2C2}{5C2}[/tex]
Answer:
P( B and V)=10%

The elevator of a building is currently 10 feet above ground level on the first floor. The building's elevator rises at a rate of 5 feet per second. You enter the elevator on the first floor. Let t, represent the number of seconds you are in the elevator and h(t) represent the height of the elevator (in feet). Write an equation for h(t) b. What will your height be in 12 seconds? c. What does h(5) = 35 represent?
Answer:
[tex]h(t) = 10 + 5t[/tex]
70 feet
Your height in 5 seconds is 35 feet
Step-by-step explanation:
From the question, we understand that:
[tex]Initial\ Height = 10[/tex]
[tex]Rate = 5[/tex] per second
Solving (a): Equation for h(t)
This implies that the height at t seconds and is calculated as thus:
[tex]h(t) = Initial\ Height + Rate * t[/tex]
Where t represents seconds
Substitute values for Initial Height and Rate
[tex]h(t) = 10 + 5* t[/tex]
[tex]h(t) = 10 + 5t[/tex]
Solving (b): Height in 12 seconds
This implies that:
[tex]t = 12[/tex]
Substitute 12 for t in [tex]h(t) = 10 + 5t[/tex]
[tex]h(12) = 10 + 5 * 12[/tex]
[tex]h(12) = 10 + 60[/tex]
[tex]h(12) = 70[/tex]
Hence, your height will be 70 feet
Solving (c): h(5) = 35 means?
Using the illustration in (b) above;
This means that your height in 5 seconds is 35 feet

Sketch a 9 red counters and 4 yellow counters.How many zero pairs can you make?How many counters do you have after you remove the zero pairs? What do they represent
Answer:
36.75 and 1/6 ( 6 accounts equally distributed )
Step-by-step explanation:
Number of Red counters to be sketched = 9
Number of Yellow counters = 4
The number of Zero pairs that can be made = 36.75
When you remove the Zero pairs the number of counters you would have = 6 accounts ie. 1/6
Mr. Perkins wants to rent a car for a day. It will cost the daily fee of $75 plus $0.55 per mile driven, which expression shows the amount he will pay if m=the number of miles driven?
A. 75m+.55
B. 75+0.55m
Answer:
B. [tex]75 + 0.55m[/tex]
Step-by-step explanation:
We know that the constant is $75. You only pay this once.
Whereas $0.55 you pay per mile. Which means that you will multiply 0.55 by how many miles you drive.
This means that the equation will look like:
[tex]75 + 0.55m[/tex]

Point A is the incenter of triangle DEF. Point A is the incenter of triangle D E F. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Y, and A Z. Which must be true? Select three options
The points must be true for Point A which is the incenter of triangle DEF are 1> Point A is the center of the circle that passes through points X, Y, and Z. 2>Line segment A X is-congruent-to line segment A Y . 3> Point A is always inside triangle DEF .
What is incenter of triangle?
The incenter of a triangle is the point of intersection of all the three interior angle bisectors of the triangle. This point is equidistant from the sides of a triangle, as the central axis's junction point is the center point of the triangle's inscribed circle. The incenter of a triangle is also known as the center of a triangle's circle since the largest circle could fit inside a triangle. The circle that is inscribed in a triangle is called an incircle of a triangle.
According to the question
Point A is the incenter of triangle DEF .
Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Y, and A Z. (X,Y,Z are points on middle of sides )
Now,
According to the properties of incenter of the triangle
1.> The circle that is inscribed in a triangle is called an incircle of a triangle.
i.e
Point A is the center of the circle that passes through points X, Y, and Z.
2> The incenter of a triangle is equidistant from the sides of a triangle, as the central axis's junction point is the center point of the triangle's inscribed circle.
i.e
Line segment A X is-congruent-to line segment A Y .
3> A triangle's incenter always lies inside the triangle.
i.e
Point A is always inside triangle DEF .
Hence, The points must be true for Point A which is the incenter of triangle DEF are 1> Point A is the center of the circle that passes through points X, Y, and Z. 2>Line segment A X is-congruent-to line segment A Y . 3> Point A is always inside triangle DEF .

The length of a room is 2 1/2 feet more than its width. If the perimeter of the room is 80 feet, find its width and length?
Answer:
The width is 20.625 and the length is 19.375
Step-by-step explanation:
Let 2 1/2 + w = length
Let w = width
Equation:
2 1/2 + w + w = 80 Combine liked terms
2 1/2 + 2w = 80
-2 1/2 -2 1/2 Subtract 2 1/2 from both sides
2w = 77.5
÷ 2 ÷ 2 Divide 2 from both sides
w = 41.25
Length:
2 1/2 + 41.25 = 165/4 or 38.75
Width:
41.25
41.25/2 = 20.625
38.75/2 = 19.375

Answer:
All you have to do is find 20% of 25
Remember that you have to change the percent to decimal
20% = 0.2
0.2 × 25 = 5
The equation that should be used to find the number of oak trees on the property is 20% of 25.
Given that,

Step-by-step explanation:
The school that Jill goes to is selling tickets to fall musical. On the first day of ticket sales the school sold 2 senior citizen tickets and 5 student tickets for a total of $50.12 the school took in $78.12 on the second day by selling 6 senior or citizen tickets and 3 student tickets. Find the price of a senior citizen ticket and the price of a student ticket.
Answer:
The price of senior citizen ticket is $10.01 and the price of student ticket is $6.02.
Step-by-step explanation:
Let the price of senior citizen ticket be $x
and the price of student ticket be $y.
Now, from the question
The school sold 2 senior citizen tickets and 5 student tickets for a total of $50.12. That is
2x + 5y = 50.12 ...... (1)
Also from the question,
The school took in $78.12 by selling 6 senior or citizen tickets and 3 student tickets. That is
6x + 3y = 78.12 ...... (2)
Now, we will bring the two equations together and solve simultaneously
2x + 5y = 50.12 ...... (1)
6x + 3y = 78.12 ...... (2)
From equation (2)
6x + 3y = 78.12 ...... (2)
Make y the subject of the formula
Then,
3y = 78.12 - 6x
∴y = 26.04 - 2x ...... (3)
Substitute the value of y into equation (1)
2x + 5y = 50.12 ...... (1)
2x + 5(26.04-2x) = 50.12
2x + 130.2 - 10x = 50.12
Collect like terms
2x - 10x = 50.12 - 130.2
-8x = -80.08
8x = 80.08
x = 80.08 / 8
x = 10.01
Now, to determine y, substitute the value of x into equation (3)
y = 26.04 - 2x
y = 26.04 -2(10.01)
y = 26.04 - 20.02
y = 6.02
∴ x = 10.01; y = 6.02
Recall that, the price of senior citizen ticket is $x and the price of student ticket is $y.
Hence, the price of senior citizen ticket is $10.01 and the price of student ticket is $6.02.
