Answer:
Step-by-step explanation:
first of all, we need to divide $45 and the 3, we get 15, so shes making 15 dollars an hour. do 15 x 5=75. so the answer is 75
∠1 and ∠2 are complementary angles. ∠1 = x° ∠2 = (3x 30)° Using this information, find the value of x. Question 6 options: x = 50 x = 75 x = 15 x = 150.
Answer: Assuming 3x 30 = 3x+30, x = 15
Step-by-step explanation:
Complementary angles sum to 90.
Therefore, x + 3x + 30 = 90
4x = 60
x = 15

In the solid pictured, the cylinder has a radius of 4 cm and a height of 10 cm. There is a hole in the cylinder in the shape of a square prism. The base of the prism has side lengths 4 cm.
Calculate the volume of the solid. Round your answer to the nearest tenth.
Answer:
342.7 cubic cm
Step-by-step explanation:
see image
Calculate the volumes of the cylinder and the prism. Subtract.
see image.
Volume is the amount of three-dimensional space enclosed by a closed surface. The volume of the solid is 342.655 cm³.
What is volume?The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity called volume.
The volume of Cylinder = πr²hThe volume of Prism = Area of prism × hThe volume of the solid is the difference between the volume of the cylinder and the volume of the square prism.
[tex]\text{Volume of the solid} =\text{Volume of the cylinder}-\text{Volume of the square prism}[/tex]
[tex]\text{Volume of the solid} =(\pi r^2 h)-(a^2 h)[/tex]
We know that the radius of the cylinder is 4 cm while the length of the side of the square prism is 4 and the height of both is 10cm. therefore, substituting the values,
[tex]\text{Volume of the solid} =(\pi\times 4^2 \times 10)-(4^2 \times 10)[/tex]
[tex]=4^2\times10 (\pi -1)\\\\= 342.655\RM\ cm^3[/tex]
Hence, the volume of the solid is 342.655 cm³.

What is the probability of winning a game of checkers against my friend?
Probability can be described as the process of determining the chances of an event happening. The chances that an event would occur has a value that lies between 0 and 1. A value of 0 is given when the event does not occur and a value of 1 if the event occurs.
The probability of winning a game of checkers = probability of winning both games / probability of winning a game of chess

Complete the steps to evaluate the following expression, given log3a = −0. 631. Log3 a 3.
The completed steps to evaluate the given expression is [tex]a = 3^{-0.631} \approx 0.5[/tex]
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = log_a(c)[/tex]
Some properties of logarithm are:
[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) + \log_b(c) = \log_a(c)[/tex]
Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.Log with base 10 is written as [tex]\log(x)[/tex] simply.The considered equation is [tex]\log_3(a) = -0.631[/tex]

We can find a system of congruences where x≡a (mod 4) x≡b (mod 5) where the solution is x≡7 (mod 20).
If x ≡ 7 (mod 20), then
x ≡ 7 ≡ 27 ≡ 47 ≡ 67 ≡ 87 ≡ … (mod 20)
or equivalently, x = 7 + 20k for some integer k.
Taken mod 4, we have
x ≡ 7 + 20k ≡ 3 (mod 4)
and mod 5,
x ≡ 7 + 20k ≡ 2 (mod 5)
so that a = 3 and b = 2.

The cost of going to a drive-in movie theater is $5.50 per person plus $2.75 per car. It has to create an algebraic equation that shows how many people can go to the drive-in with one car for $19. 25.
Suppose the total number of people in the car for drive-in movie theater is x. Thus, the cost of the x person to watch the movie is,
[tex]C=5.50x[/tex]
As the cost of one car is $2.75. Thus, the total cost of watching a movie by x person will be,
[tex]C=5.50x+2.75[/tex]
Now, the total cost, drive-in with one car for $19. 25. This cost must be equal to the above expression for total cost. Therefore,
[tex]C=5.50x+2.75=19.25[/tex]

Answer: D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports
Step-by-step explanation: If you add up all the number of visitors, you'll get 80. Since we want to find the numbers for the next 200 visitors, we'll divide 200 by 80, which will get us 2.5. Then you'll multiply all the numbers by 2.5 to get:
Camping = 70
Hiking Trails = 55
Water Sports = 35
Biking Trails = 40
After that, you'll just compare the numbers to get your answer.
whats the length of each side of an equilateral triangle if the perimeter is 33
Answer:
11
Step-by-step explanation:
A triangle has 3 sides.
Add up all the sides to get the perimeter.
So.... divide the perimeter (33) by the number of sides (3) and you get the length of each side. (11)
[tex]33/3 = 11[/tex]
We can check this by using the perimeter of a triangle formula. [tex]P = a + b +b[/tex]
[tex]P = 11+11+11[/tex]
[tex]P = 33[/tex]
