At a zoo, the price of 4 adult tickets and 6 child tickets is $77.The price of 6 adult tickets and 4 child tickets is $83. What is the ticket price for one adult and for one child?
Answers
Answer:
the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5
Step-by-step explanation:
Given that:
the price of 4 adult tickets & 6 child tickets = $77
the price of 6 adult tickets & 4 child tickets = 83
then the price of 1 adult ticket and 1 child ticket will be:
Let assume that the cost of 1 adult ticket to be $p
Then;
the cost of 4 adult ticket = $4p
Similarly, the cost of 6 adult ticket = $6p
However, assuming that the cost of 1 child ticket is $q
Then;
the cost of 6 child ticket = $6q
the cost of 4 child ticket = $4q
∴
We can express them with their given prices that:
4p + 6q = 77 --- (1)
6p + 4q = 83 --- (2)
From equation (1), let 4p = 77 - 6q
Then; [tex]p = \dfrac{77 - 6q}{4}[/tex]
replace the value of p into equation (2)
∴
[tex]6 \Big ( \dfrac{ 77 - 6q }{4}\Big) + 4q = 83[/tex]
[tex]\dfrac{462 - 36q}{4}+ 4q = 83[/tex]
[tex]115.5 - 9q + 4q = 83 \\ \\ 115.5 -5q= 83 \\ \\ 115.5 - 83 = 5q \\ \\ 32.5 = 5q[/tex]
[tex]q= \dfrac{32.5}{5}[/tex]
q = 6.5
Since q = 6.5, then using equation (1)
4p + 6(6.5) = 77
4p +39 = 77
4p = 77 -39
4p = 38
p = 38/4
p = 9.5
Thus, the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5

Step-by-step explanation:
Pack of 4 = £1
Packs of 6 = £1.20

Pack of 4 ;
Unit price : cost / units
Unit price = £1 / 4 = £0.25
Pack of 6 ;
Unit price : cost / units
Unit price = £1.20 / 6 = £0.20
Pack of 6 is the best value for money as it has a lower unit price
how do you work out what 8 cubed is ?
Answers
Step-by-step explanation:
so do you have building blocks cuz you use it and then after you do that you get the cue that has an eight on it and then you would keep on adding on and then that would be the answer
Answer:
512.
Step-by-step explanation:
8 cubed is the same as 8 to the third power.
We usually use other ways to represent certain number to the power to help make equations easier and write less so,
instead of saying: 2 to the second power; we say 2 squared.
Instead of saying 2 to the third power; we say 2 cubed.
The number 2 was used just as example, it could be any number.
so 8 cubed = 8 to the third power so,
8 cubed = [tex]8^{3}[/tex] = 8x8x8 = 512

Write an expression to show 5 fourths times the product of 3 and 1 fourth.
Answers
Answer:(5/4)(3/4)
Step-by-step explanation:
Hello,
First of all, an expression does not have an equal sign, unlike an equation.
First, start with the fraction 5/4.
Second, know that the whole number, 3, and the fraction, 1/4, are being multiplied.
(3)(1/4)=(3*1)/4=3/4
Finally, 5/4 * the product of 3 and 1/4 is:
(5/4)(3/4)

I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025 $ 1025 plus 13% 13 % of his monthly sales. Write a linear equation for his monthly income for sales of x dollars. ( I=mx+b I = m x + b ).
Answers
Answer:
l = 0.13x+1025
Step-by-step explanation:
Let the monthly sales be x
Monthly income = $1025 + 13% of monthly sales
Monthly income = $1025 + 0.13x
Since l represent the monthly income
l = 1025+0.13x
Rearrange
l = 0.13x + 1025
Hence the linear equation representing the statement is l = 0.13x+1025

A container in the shape of a pyramid has a rectangular base with dimensions of 5 inches by 15 inches. The height of the rectangular pyramid is 12 inches. Marbles fill half the volume of the container. How many more cubic inches of marbles are needed to finish filling the container?Enter your answer in the box.
{ }in3
Answers
Answer:
First you find the volume of the pyramid:
1. find the area of the base:
A= 15 x 5= 75
2. Multiply the Area of the rectangle by the height; h= 12 and si use the result by 3.
V= A x h /3 =. 75 x 12 = 900 /3
V= 300
3. If only 1/2 is filled, that means
V= 300/2= 150 in3 is filled and
150 in3 of marbles is needed to fill the container.

Eve took one of her friends out to lunch. The lunches cost $100 and she paid 3% sales tax. If
Eve left a 15% tip on the $100, how much in total did she pay?
Answers
Tax: 3% = 3/100= 0.03
So 0.03 X $100 = $3 in tax
Tip: 15% means 15/100 = 0.15
0.15 X 100 = $15
So tax was $3, tip was $15, and bill was $100, all added up is $118

At the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that Sarah has a coupon for 25% off any item at the big fish store. If she buys an item regularly marked $60,
Sale price =Original price - discount
Sale price = $60 - 25% of $60
Sale price = $60 - $ 15
Sale price = $45
Thus, at the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.

Mathilde has 20 pints of green paint. She uses 2/5 of it to paint a landscape and 3 /10 of it while painting a clover. She decides that, for her next painting, she will need 14 pints of green paint. How much more paint will she need to buy?
Answers
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed
