Answer:
[tex]n(A \cup B) = 6[/tex]
Step-by-step explanation:
In Venn sets, we have that:
[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)[/tex]
In which n is the number of elements that each set contains.
In this question:
[tex]n(A) = 8, n(B) = 9, n(A \cap B) = 6[/tex]
So
[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B) = 8 + 9 - 6 = 17 - 6 = 11[/tex]
So
[tex]n(A \cup B) = 6[/tex]

Dennis Hampton earns a straight com-
mission of 7% on sales of $5,000 or less
and 9% on sales in excess of $5,000. One
week Dennis had a gross pay of $578.
What were his total sales for that week?
Answer:
Denis's total sales that week were $ 6,422.22.
Step-by-step explanation:
Since Dennis Hampton earns a straight commission of 7% on sales of $ 5,000 or less and 9% on sales in excess of $ 5,000, if one week Dennis had a gross pay of $ 578, to determine what were his total sales for that week the following calculations must be performed:
7 = 578
100 = X
100 x 578/7 = X
57,800 / 7 = X
8,257.14 = X
9 = 578
100 = X
100 x 578/9 = X
57.800 / 9 = X
6,422.22 = X
Therefore, Denis's total sales that week were $ 6,422.22.
1 Remy has 4 monster trucks, 3 firetrucks, 1 ambulance, and 2 taxis. He will randomly choose. what is the probability that Remy will choose a taxi
A 1/10
B 1/5
C 2/4
D 1/3
Answer:
B) 1/5
Step-by-step explanation:
Remy has 2 taxis, and 10 cars in all. It is asking for the probability that Remy will choose a taxi. Divide the amount of taxis from the total amount of cars. Simplify the fraction:
2/10 = (2/10)/(2/2) = 1/5
B) 1/5 is your answer.

Find an ordered pair (x,y) that is a solution to the equation.
5x+y=6
Answer:
(0,6) and (1.2 , 0)
Step-by-step explanation:
5x + y = 6
if we take x=0
5(0) + y = 6
y = 6 ; so, one of the solution is (0,6)
if we take y=0
5x + (0) = 6
5x = 6
x = 6/5 = 1.2 ; so, the other solution is (1.2 , 0)
But basically, you can find other solutions of the equation if you do this:
5x + y = 6
5x = (6 - y)
x = (6 - y) / 5 ; so if you use whatever number of y, you will find the rigth solution for x.
and you can do the opposite too:
5x + y = 6
y = 6 -5x ; with this, you can use whatever number of x, and find the right y.
I hope this helps you!!!
8) Lisa and Jasmine are selling cheesecakes for a school fundraiser. Customers can buy pecan
cheesecakes and apple cheesecakes. Lisa sold 3 pecan cheesecakes and 7 apple cheesecakes for a
total of $130. Jasmine sold 12 pecan cheesecakes and 14 apple cheesecakes for a total of $338.
Find the cost each of one pecan cheesecake and one apple cheesecake.
9514 1404 393
Answer:
both cost $13 each
Step-by-step explanation:
Let p and a represent the costs of pecan and apple cheesecakes, respectively.
3p +7a = 130 . . . . . . Lisa's sale
12p +14a = 338 . . . . Jasmine's sale
Both the ratios of p-coefficients (4) and a-coefficients (2) are "nice" numbers, so "elimination" is a viable solution method here.
Subtracting twice the first equation from the second eliminates 'a'.
(12p +14a) -2(3p +7a) = (338) -2(130)
6p = 78 . . . . . simplify
p = 13 . . . . . . .divide by 6
Substituting into the first equation gives ...
3(13) +7a = 130
7a = 91 . . . . . . . subtract 39
a = 13 . . . . . . . . divide by 7
The cost of one pecan cheesecake is $13; the cost of one apple cheesecake is $13.

A graphing calculator can solve the two equations nicely. Below is a graph of them, showing the solution is (p, a) = (13, 13). Graphing calculators and some scientific calculators can also solve these equations when they are written in matrix or augmented matrix form. It can be worthwhile to learn how to use these calculator features.

in a population of grasshoppers, the ratio of grasshoppers with a white marking to those without a white marking is 2:3. An entomologist captures and photographs 290 grasshoppers. How many photographs are likely to show grasshoppers with a white marking?
A. 193
B. 58
C. 112
D. 116
Answer:
D. 116
Step-by-step explanation:
Let the grasshoppers with a white marking be 2x.
Let the grasshoppers without a white marking be 3x.
2x + 3x = 290
5x = 290
x = 290 / 5
x = 58
The grasshoppers with a white marking
= 2x
= 2 ( 58 )
= 116

Help me please!!!!! I need help with angles
Answer:
<CFE = 28
<RPQ = 53
Step-by-step explanation:
1)
<CFE + 152 = 180
<CFE = 180 - 152
<CFE = 28
2)
Complementary means the angles add up to 90 so:
<RPQ + 37 = 90
<RPQ = 90 - 37
<RPQ = 53

A rectangular prism has a length of 112feet, a width of 212feet, and aheight of 8 inches. What is the volume of the prism in cubic inches?
pls hurry :)
Answer:
27,353,088 cubic inches
Step-by-step explanation:
How to find the volume of a rectangular prism
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Solve
In this case, The volume of a rectangular prism with a length of 112feet,
width of 212 feet, and height of 8 inches:
But in this case, we need to convert both the length and width to inches.
If 1ft = 12in
Then, 112ft = 1344in (Multiply 112 by 12)
Also, 212ft = 2544 (Multiply 212 by 12)
So, the volume = 1344 x 2544 x 8
Calculated out this gives a volume of 27,353,088 cubic inches.
