On a certain hot summer's day, 622 people used the public swimming pool. The
daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $1115.00.
How many children and how many adults swam at the public pool that day?
Answer:
There were 257 children and 365 adults at the public pool.
Step-by-step explanation:
Let the number of children and adult be x and y respectively,
x+y = 622
1.5x+2y = 1115
Now,
x+y = 622
or, x = 622 - y
Now,
1.5x + 2y= 1115
or, 1.5(622-y) + 2y = 1115
or, 933 - 1.5y + 2y = 1115
or, 933 + 0.5y = 1115
or, 0.5y = 1115-933
or, 0.5y = 182
so, y = 182/0.5
so, y = 365
Now,
x+y = 622
or, x + 365 = 622
so, x = 257

What is the equation of the line that passes through the point (7,-3) and has an undefined slope?
Answer:
X = 7
Step-by-step explanation:
Any line with a undefined slope is a vertical line, which goes up and down.
Since this is a vertical line, and our x-value is 7, this means that the vertical line has the x-coordinate 7 at all times, making the equation x = 7.

The answer to the question is 10
Answer:
10Step-by-step explanation:
To simplify the expression, open the brackets to obtain your result.
(4x + 5) - (4x - 5)→ 4x + 5 - (4x - 5)→ 4x + 5 + (-4x + 5)→ 4x + 5 - 4x + 5→ 5 + 5→ 10Hence, the result is 10.

A person places $60100 in an investment account earning an annual rate of 5.3%, compounded continuously. Using the formula V = P e r t V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 19 years.
Answer:
$164516
Step-by-step explanation:
Solution P = 60100 + = 19 r = 5.3/100
V= Pe
V= 60100 e 5.3x19/100
V= $164516
Answer:
164,516.33
Step-by-step explanation:
r = 5.3% = 0.053
p = 60100
t = 19
V = Pe^(rt)
Plug It In:
V = 60100e^0.053(19)
V = 60100e^1.007
V = 164516.3309 ≈ 164516.33

Investigate the weather forecast in your city.
Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.

Write a mathematical expression using the information from your table to answer the following questions:
What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.
What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
The average change in high temperatures over the next 7 days is 2.3. On the other hand, the average low temperature is 2.8.
How to calculate the average?To calculate the average of several values, we must perform a two-step mathematical operation:
We must add all the values.We must divide the previous result by the number of values we have.Below is the example with the values in the table.
High temperature:
1 + 3 + 2 + 2 + 5 + 1 = 1414/6 = 2.3Low temperature:
3 + 1 + 3 + 4 + 4 + 2 = 1717/6 = 2.8Learn more about average in: https://brainly.com/question/2426692

An american man wants to break the guinness Record or largest pizza. He manages to bake with a radius of 66 feet. he offers to feed his town. if he cuts a slice with a central angle of 37* , how much area would this slice cover?
Answer:
4418.6 square feet
Step-by-step explanation:
The area of a sector of a circle is given by the formula ...
A = 1/2r²θ . . . . where r is the radius, and θ is the central angle in radians
__
The area of the proposed pizza slice is the area of a sector with a radius of 66 ft and a central angle of 37°. That area will be ...
A = 1/2(66 ft)²(37°×π/180°) ≈ 4418.6 ft²
The pizza slice would cover 4,418.6 square feet.
_____
Additional comment
There are 2π radians in the 360° of a circle. That means ...
1 radian = 180°/π ≈ 57.296°
1° = π/180 radians
As we have done above, the number of radians can be found by multiplying the degree measure by π/180°. The units of degrees will cancel, leaving a "pure number" with no units. That is, "radians" is a non-unit: a number of radians is a pure number.
