A local carnival charges $7.50 for adult admission and $5.25 for child admission. The carnival made $378 in an hour. The carnival
admitted twice as many children as adults.
How many adults and children were admitted in the hour?
Answer:
21 adults42 childrenStep-by-step explanation:
You want to know how many adults and children were admitted if there were twice as many children who paid $5.25 for admission as there were adults who paid $7.50, and total admission revenue was $378.
SetupLet 'a' represent the number of adults admitted. Then 2a is the number of children. The total revenue is ...
7.50a +5.25(2a) = 378
SolutionCollecting terms, we have ...
18a = 378
a = 21 . . . . . . . divide by 18
2a = 2·21 = 42 . . . . . find the number of children admitted
21 adults and 42 children were admitted.
21 adults were admitted.
42 children were admitted.
Describe algebra.Algebra is one of the numerous subfields of mathematics. The study of mathematical symbols and the rules for employing them in formulas is commonly referred to as algebra, which runs across almost all of mathematics.
Due to that,
Carnival earns a total of $378 in one hour.
Adult fees are $7.50.
Children's fees equal $5.25
Suppose that the carnival allows twice as many youngsters as adults.
If there are x adult, then
Children will thereafter be twice as many.
Since,
$378 is the total amount from both adults and children.
Then,
7.50x + 5.25(2x) = 378
7.50x + 10.50x = 378
18x = 378
x = 378 / 18
x = 21
As x was the total number of adults
Then, in an hour, 21 adults were admitted.
Since there were a total of two children,
Next, there were
42 kids were admitted in an hour (2(21)).
As a result, 42 kids and 21 adults were admitted in one hour.

Area is 314.2 cm²
Step-by-step explanation:
- Consider a circle whose radius is r, while calculating its area, the formula is derived from its circumference;

Adam’s house is 12 miles from his house. It takes his older brother 20 minutes to drive him school. What is his brother’s driving speed
Step-by-step explanation:
I assume we want ca miles/hour answer as speed.
but just formally, any distance per time unit is speed.
in that sense
12 miles / 20 minutes = 3 miles / 5 minutes
is the speed.
but now to convert this to miles/hour.
we want to multiply 3/5 or 12/20 by f/f, so that the denominator is 1 hour.
by multiplying the numerator by the same value we make sure the speed ratio remains the same.
so, what "f" do we need to multiply 20 with to get 60 (1 hour = 60 minutes) ?
right, f = 3
therefore, we get
12/20 × 3/3 = (12×3)/(20×3) = 36/60 = 36 miles / 1 hour
his brother's driving speed was 36 miles/h or 36 mph.
A toy company that makes bubbles fills its 8-ounce bottles using a machine. To check that the machine fills the bottles with the proper amount, the company randomly checks bottles off the assembly line.

The range of values that a bottle could contain to pass inspection will be 7.840 - 8.160 ounces.
How to calculate the value?It was stated that the toy company that makes bubbles fills its 8-ounce bottles using a machine.
The bottle passes inspection if the percent error of the amount is 2% or less. The minimum range will be:
= 8 ounces - (2% × 8 ounces)
= 8 ounces - 0.16 ounces

Given, the allowable percentage error is 2% or less.
Now, 2% of 8 ounces is,
= (2/100)×8.
= 0.16 ounces.
So, the allowable range is from (8 - 0.16) = 7.84 ounces to
(8 + 0.16) = 8.16 ounces.

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.

Two similar triangles are shown below:
Two triangles are shown. The sides of the triangle on the left are marked 4, 5, 6. The sides of the triangle on the right are marked as 3, 2, and 2.5. For the triangle on the left, the angle between sides marked 6 and 5 is labeled as a, marked by a double arc, and the angle between the sides marked 6 and 4 is labeled as b, marked by a single arc. The third angle is marked by a triple arc. For the triangle on the right, the angle between sides marked 2 and 3 is labeled as c and the angle between the sides marked 2.5 and 3 is labeled as d, marked by a double arc. The angle between the sides 2 and 2.5 is labeled as e, marked by a triple arc, and it is also the angle on the top vertex of this triangle.
Which two sets of angles are corresponding angles? (4 points)
Group of answer choices
∠a and ∠e; ∠b and ∠c
∠a and ∠c; ∠b and ∠d
∠a and ∠e; ∠b and ∠d
∠a and ∠d; ∠b and ∠c
Step-by-step explanation:
the 2 triangles are similar.
that means their corresponding angles are equal, and their side lengths (and heights and so on) have all the same constant scaling factor.
so, we see that the side with the length 6 must corresponds to the side with the length 3 (factor 1/2).
as then the side with the length 5 corresponds to the side with the length 2.5, and the side with the length 4 corresponds to the side with the length 2 (all have the same factor 1/2).
a is the angle between 6 and 5 (the 2 longest sides).
the angle between the 2 longest sides in the smaller triangle (3 and 2.5) is d.
so, a and d correspond.
b is the angle between 6 and 4 (the longest and the shortest side).
the angle between the corresponding sides 3 and 2 is c.
so, b and c correspond.
therefore, the 4th and last answer choice is correct.

Option D is true.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ log₅ (1/25)
Now,
Solve the expression as;
⇒ log₅ (1/25)
Since, log (a/b) = log a - log b
Hence,
⇒ log₅ (1/25) = log₅ 1 - log₅ 25
Since, log 1 = 0
⇒ log₅ (1/25) = 0 - log₅ 25
⇒ log₅ (1/25) = - log₅ 5²
Since, log a² = 2 log a
⇒ log₅ (1/25) = - 2 log₅ 5
Since, log₅ 5 = 1
⇒ log₅ (1/25) = - 2 x 1
⇒ log₅ (1/25) = - 2
Thus, The value of the expression will be;

This logic also applies to finding the next term with the answer to the previous term) The formula is an = a(n-1) + 6. Because of this formula the nth on the right side is the previous one plus 6. With that in mind let find the mext three terms To find a2 you would first substitute n for 2 making it a2 = a(2-1) +6 which is a2 = a1 + 6. We know that the first term is 3 so we substitute a1 for 3 to get a2 = 3 + 6 which is 9. The second term is 9 To find a3 we do the same steps for solving a2 only this time we use the second term to put in place of a2+ 6 which is 9 + 6 which equals to 15. The third term is 15 Again we are doing the same steps to find a4 but we use the third term to substitute for a3 + 6 which is 15 + 6 which equals to 21. The fourth term is 21.There's a image of all of the work above
