A system of linear equations to describe this situation is given by:
A + O = 11.
0.80A + 0.95O = 9.95.
Harry bought six (6) apples and five (5) oranges from this store.
How to write a system of linear equations?In order to write a system of linear equations to describe this situation, we would assign variables to the amount of apples and oranges respectively, and then translate the word problem into algebraic equation as follows:
Let the variable A represent the amount of orange Harry bought.Let the variable O represent the amount of apple Harry bought.Since Harry bought a total of 11 pieces of fruit, we have:
A + O = 11 .....equation 1.
Since the cost of apples is $0.80 each and oranges cost $0.95 each, we have:
0.80A + 0.95O = 9.95 .....equation 2.
Part B.From equation 1, we have:
O = 11 - A .....equation 3.
Substituting equation 3 into equation 2, we have:
0.80A + 0.95O = 9.95
0.80A + 0.95(11 - O) = 9.95
Apples, A = 0.90/0.15
Apples, A = 6.
For the number of oranges, we have:
Oranges, O = 11 - A
Oranges, O = 11 - 6

Booker's father amount of commission earned is 668.31 dollars.
Sophia needs to make sells of 16744 dollars in order to earn at least 1800 dollars in commission.
How to find how much commission Booker's father will earn?Booker's father sells computer software and earns a 4.25% commission on every software package he sells.
The amount of commission he will earn after selling a software package of $15, 725 can be calculated as follows:
amount of commission earned = 4.25% of 15725
amount of commission earned = 4.25 / 100 × 15725
amount of commission earned = 66831.25 / 100
Therefore,
amount of commission earned = 668.3125
amount of commission earned = 668.31 dollars
Sophia needs to earn at least 1800 dollars each month to cover her living expenses.
The minimum she needs to sell in order to earn at least 1800 dollars if she earns 10.75% commission can be calculated as follows:
let
x = amount she needs to sell
Therefore,
10.75% of x ≥ 1800
10.75 / 100 x ≥ 1800
multiply both sides by 100
10.75x ≥ 180000
divide both sides by 10.75
x ≥ 16744.1860465
x ≥ 16744
Therefore, she needs to sell 16744 dollars worth of goods.

The probability of getting someone in the 18-21 age bracket or someone who responds is 28.7%.
The total number of people in the 18-21 age bracket is 93. The number of people in this bracket who responded is 79. The number of people in this bracket who refuse to respond is 14. The total number of people in the 22-29 age bracket is 251. The number of people in this bracket who responded is 219. The number of people in this bracket who refuse to respond is 32.
A person is randomly selected from all the people surveyed. We need to find out the probability of getting someone in the 18-21 age bracket or someone who responds. Let the variables E1 and E2 represent the events.
E1 is the event of getting a person from the 18-21 age bracket.
E2 is the event of getting a person who responds.
P(E1∪E2) = P(E1) + P(E2) - P(E1∩E2)
P(E1∪E2) = (93/344) + [(79 + 219)/344] - (79/93)
P(E1∪E2) = 0.27035 + 0.86628 - 0.84946
P(E1∪E2) = 0.28717
Hence, the probability of getting someone in the 18-21 age bracket or someone who responds is 28.7%.

degrees?
(X,y) -> (-X,-y)
(X,y) -> (X,-y)
(X,y) -> (y,X)
(X,4) -> (-X,4)
The required rotation of the 180° is given by, (X,y) -> (-X,-y), option A is correct and the required translation is given by (x + 6, y - 2), option D is correct.
Given that,
To determine which option shows the rotation of 180°, and translation of right 6 units and down 2 units.
Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
For the rotation of the 180°, the given coordinate undergoes the change in direction so the required coordinate after 180° rotation is given as (-x, -y).
Now, for the translation of 6 units right we must add x with 6 and for 2 units down we must subtract y by 2, the required translation is given as(x + 6, y -2).
Thus, the required rotation of the 180° is given by, (X,y) -> (-X,-y), and the required translation is given by (x + 6, y - 2).

A measure of an angle or of a rotation is also referred to as an angle. The ratio of a circular arc's length to radius is known as this quantity. When it comes to a geometric angle, the arc's vertex serves as its center and its sides as its boundaries. When there is a rotation, the arc is defined by the rotation's image and any other point other than the rotation's center.

Apply the distributive property to the following expression: 2n (5m -1)
I need HELP!! ASAP!!
By using the distributive property, we will rewrite the expression as:
2n*(5m -1) = 10*n*m - 2n
How to apply the distributive property?
The distributive property of the multiplication says that the product:
A*(B + C)
Can be rewritten as:
A*(B + C) = A*B + A*C
So we are "distributing" the product.
In this case, we have the expression:
2n*(5m - 1)
If we apply the distributive property, then we will get:
2n*(5m - 1) = (2n)*(5m) + (2n)*(-1)
Now we can simplify this expression to get:
(2n)*(5m) + (2n)*(-1) = 10*n*m - 2n

Work Shown:
F = (9/5)*C + 32
F = (9/5)*27 + 32
F = 80.6
F = 81
Side note: 9/5 = 1.8
Answer:
81 degrees Fahrenheit.
Step-by-step explanation:
Using the standard Fahrenheit-Celsius conversion formula.
27 * 9/5 = 48.6.
48.6 + 32 = 80.6.
Rounded to 81.
Therefore 81 degrees Fahrenheit.
find the values of x, y, and z.
To find x, you would do 180-36-63, which would be 81.
Then you would do 180-81 to find z, which is 99.
To find y, would do do 180-99-13, which is 68.
Answer:
x=81
y=68
Z=99
Step-by-step explanation:
to find x we have to remember the rule that all 3 angles sum up to be 180 in a triangle
So we use this to find x
180-(63+36)=x
180-99=x
81=x
Now to find z since it is on a flat plane you just subtract 81 from 180 to find z
180-81=z
99=z
Now to find y we add all the angles of the second triangle and then subtract that sum by 180
180-(13+99)=y
180-112=y
68=y

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The shelf is perpendicular to the wall.
The shelf makes an angle of 90 degree to the wall because when the shelf is perpendicular then the wall and shelf should be ninety degrees.
From the shelf edge to wall there creates an angle x.
We need to find the angle x.
