Answer:
The total cost in dollars, y = $7n.
Step-by-step explanation:
a) Data and Calculations:
Price of hot dogs = $2,75 each
Price of drinks = $1.50 each
Cost of hot dogs bought by one person = 2*2.75 = 5.5
Cost of drinks bought by one person = 1.50
Number of people in a group = n
y = total cost in dollars
y= n($5.5 + 1.50)
y = n * $7
y = $7n
b) Each person's purchase of hot dogs will cost $5.5 (2*2.75). When the cost of hot dogs per person is added to the cost of drinks per person, we have $7 ($5.50 + 1.50). This implies each person will consume hot dogs and drinks worth $7. The total cost will then be $7 multiplied by n, the number of people ($7n).

convert 8.132132132... to a rational expression in the form of a fraction
Let x = 8.132132132... .
Then 1000x = 8132.132132132... .
Subtracting x from 1000x eliminates the fractional part, leaving you
999x = 8132 - 8 = 8124
Then
x = 8124/999 = 2708/333

7 girls are dancing in Circular form. In how
many ways can they stand in circle?
Answer:
I'm sorry if i'm wrong but i think Its 6.
Step-by-step explanation:
Answer:
42 I believe
Step-by-step explanation:
They way I think about it is if you think about one girl there are 6 other girls around her and so on. So 6 times 7 is 42
But it could be a trick question and it only be 7, because a circle doesn't have a definite start place like a line
And article says that 15% of a non-profits Donations about 30,000 a year comes from individual donors what is the total amount of down donations to nonprofit receives
Answer:
200,000
Step-by-step explanation:
Step one:
given data
We are given that 15% of a non-profits Donations is about 30,000
Required
The amount in total received in donation
Step two:
Let the total donation be x
so
15/100*x= 30000
solve for x
0.15*x= 30000
divide both sides by 0.15
x= 30000/0.15
x=200,000
Hence the total donation is about 200000
juliet school collected 480 can food last month witch represented 80 percent of rheir goal. What is the toatal of her goal? PLEASE HELP ME I NEED TO HAVE THIS FINISHED ITS THE LAST DAY IN THE SEMESTER FOR OVERALL GRADES!?!?!?
Answer: 600 canned foods was the total.
Step-by-step explanation: We need to find out what‘s 100% of 480. Since 480 canned foods is 80%, we can divide 480 by 8 which gives us 60. Aka 60 canned foods = 10%. Now, we multiply 60 by 10 which gives us 600. Hope this helps!
easy vector problem! show work/explain please :)
Answer:
Step-by-step explanation:
a = 2i + 3j + zk
b = xi + 1j + 4k
Given a X b = 6i -14j +5k
a X b = | i j k|
|2 3 z|
|x 1 4|
a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k
equate the coefficients of i , j and k
12- z = 6; implies z = 6
8 - xz = -14 implies 8 - 6x = -14
2-3x = 5 implies 2 - 3x = 5 implies x = -1
A glass is
1
-
3
full. Then 63cm3 of orange juice is poured in.
The glass is now
5
-
8
full.
What is the total volume of the glass?
Step-by-step explanation:
x=volume of the glass
(1/3)x+63=(5/8)x
63=(5/8)x-(1/3)x
63=(15/24)x-(8/24)x
63=(7/24)x
multiply both sides by 24/7
(24/7)(63)=(24/7)(7/24)x
216=x
216 cm3 is the volume (answer)
1/3 of 216 is 72
72+63=135
135/216=0.625=5/8

what times what equals 3/8
Answer:
1/8 * 3
Step-by-step explanation:
1/8*3 means the numerator gets multiplied by 3 so we get (1*3)/8 which is 3/8
The equivalent value of the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = pq
when the value of p = 3/4
And , when the value of q = 1/2
On simplifying the equation , we get
3/8 = ( 3/4 ) ( 1/2 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 3/4 ) ( 1/2 )
A = ( 3/4 ) ( 1/2 )
A = 3/8
Therefore , the value of A = 3/8 = ( 3/4 ) ( 1/2 )
Hence , the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Solve the problem and explain the steps you took to solve.
Answer:
Because there are 12 months in a year the ratio of the number of pieces of mail Max delivers in 12 months can be written as: 852012 or 7101 (720 pieces of mail per month).
Answer:
He would deliver 1420 mails in 2 month's
Step-by-step explanation:
First, I divided 8,520 by 12 because 12 month's in one 1 year
Then, I get 710, that is the amount he delivers each month
Lastly, I multiply 710 by 2 because that is the amount for 2 month's and it equals 1,420 so, the answer is 1,420 :)
What is the answer to this?
Answer:
Since 5 tenths is 5 over ten, 5 tenths as a Fraction is 5/10. If you divide 5 by ten you get 5 tenths as a decimal which is 0.50.
