Answer:
See explanation
Step-by-step explanation:
Let the number of adults = a and the number of children = c.
Since the number of people using the pool is 288, we know that a + c = 288
Based on the price information, we know that 1.75c + 2.5a = 528
Combining these two equations allows us to solve for the values of a and c, the process for which follows
a = 288 - c
1.75c + 2.5(288 - c) = 528
c = 256
a = 288 - c = 288 - 256 = 32
a = 32
c = 256

Find the area of the region in blue.
Round to the nearest whole number.
Answer:

The number of dollars in Chi's bank account on Tuesday was 4 times as much as the amount on Friday. How many dollars were in the account on Friday?
Answer:
Step-by-step explanation:
Since we are not given actual numerical values then we can use the available information to write an equation that calculates the final amount in the account on Friday (f). In this equation, x will be our variable that represents the amount of money in the account on Tuesday. Since the amount on Tuesday was 4 times more than on Friday, we need to divide the amount on Tuesday by 4 to get the amount on Friday.
f = [tex]\frac{x}{4}[/tex]
This equation will give us the value of the account on Friday after we input the value of x.

4400 dollars is placed in an account with an annual interest rate of 7%. To the nearest year, how long will it take for the account value to reach 10100 dollars?
Answer:
19 years approx
Step-by-step explanation:
Given data
Principal P= $4400
Rate r=7%
Final amount A=$10100
Time t= ???
Let us apply the simple interest expression
A=P(1+rt)
substitute
10100=4400(1+0.07*t)
open bracket
10100=4400+308t
10100-4400=308t
5700=308t
t= 5700/308
t= 18.50
Hence the time is 19 years approx

Find the height of a trapezoid that has an area of 64 square inches, and bases of 8 and 12 inches.
Answer:
6.4 inches
Step-by-step explanation:
Area= (a+b)/2 x h
64 in^2= (8+12)/2 x h
= 20/2 x h
= 10 x h
64 in^2 / 10 = height of 6.4 inches

i don't know english very well so i don't knoe what transplant is but i think i got it right with my logic
Answer:
m∠1 = 136°
m∠2 = 44°
m∠3 = 136°
m∠4 = 44°
m∠5 = 136°
m∠6 = 44°
m∠7 = 136°
Step-by-step explanation:
Corresponding angles, like m∠1 and m∠5, need to equal each other.
m∠1 and m∠3 are the same
m∠3 and m∠2 need to be added together to equal 180
Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x=2y-7 and 4x+y=71 *
Answer:
The solution is (15, 11) There is only one solution.
Step-by-step explanation:
Solve this system using substritution. In the second equation replace x with 2y - 7, obtaining:
4(2y - 7) + y = 71, which simplifies as follows:
8y - 28 + y = 71, or
9y = 99. then y must be 11. If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15
The solution is (15, 11) There is only one solution.
The cone and cylinder above have the same radius and height. The volume of the cylinder is 48 cm3. What is the volume of the cone?
A.
24 cm3
B.
16 cm3
C.
96 cm3
D.
144 cm3
Answer:
Option B (16 cm³)
Step-by-step explanation:
GIVEN :-
Both cone and cylinder have same radius and height.Volume of cylinder = 48 cm³TO FIND :-
Volume of coneFACTS TO KNOW BEFORE SOLVING :-
Volume of a cylinder having radius 'r' and height 'h' is [tex]\pi r^2h[/tex]Volume of a cone having radius 'r' and height 'h' is [tex]\frac{1}{3} \pi r^2 h[/tex]Hence ,
Volume of cylinder = Thrice the volume of cone
[OR]
Volume of cone = One third of volume of cylinder
PROCEDURE :-
Volume of cone = [tex]\frac{1}{3} (Volume \: of \: cylinder) = \frac{48}{3} = 16 cm^3[/tex]
Find the 8th term of the geometric sequence 6, 18, 54, ...
Answer:
13122
Step-by-step explanation:
6 x 3 = 18; 18 x 3 = 54; continue to do this 8 times and you get 13122!
Answer:
a(8) = 6*3^7 = 13122
Step-by-step explanation:
Each new term is equal to the previous one times the common ratio, r, which in this case is 3.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).
In this particular case, we have a(n) = 6*(3)^(n -1).
The 8th term of this sequence is a(8) = 6(3)^(8 - 1), which works out to:
a(8) = 6*3^7 = 13122

The cost of leveling a square park at Rs.15 per square meter is Rs.6000. Then the side of the square is ________. *
Answer:
20 m
Step-by-step explanation:
Given :
Leveling cost per square meter = 15
Total leveling cost = 6000
Number of square park leveled :
Tottal cost / unit cost
6000 / 15
= 400 m²
The length of one side of the square
Area of square = s²
where, s = side length
400 = s²
Sqrt(400) = s
s = 20 m
Length of one side = 20 m
Use π = 3.14, and round your answer to the nearest hundredth
Answer:
3.13
Step-by-step explanation:
Because the 4 is in the hundreds place. The rule for the number would be less than five so round down. 4-1=3.
The value of π to the nearest hundredth is 3.14.
What is a place value?Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
Given:
An equation,
π = 3.14
To round off the number to the nearest hundredth:
The digit at the hundredth place in decimal is 4.
And the left to the digit is 3.
The number 4 is less than the number 5.
So, there will be no changes in the approximation of the decimal number.
So, π = 3.14.
Therefore, the value is π = 3.14.

A box of chocolates costs $12. They are on sale 50% off. How much will you pay after a 9% sales tax?
Gabe paid $ 120 for 3 shirts and 2 pairs of pants.
Each shirt cost $15.
Each pair of pants cost the same amount.
The equation 3s + 2p = 120 can be used to determine p, the cost of each pair of pants.
Gabe solved the equation using the following steps:
3s + 30=120
3s= 90
s= 30
Therefore, Gabe calculates the cost for each pair of pants as $30. Did Gabe find the cost for each pair of pants correctly?
If he did, justify each step of Gabe's solution using mathematical properties.
If he did not, describe any error Gabe made in his calculations and determine the price of each pair of pants.
Answer:
3s+2p= $120
each shirt is $15
3(15)+2p= $120
45+p=120
p= $75
each pair of pants is $75 and each shirt is $15
3s+2p= $120
3(15)+ 2(75)
