the perimeter of the figure is 70 ft how long are the unknown sides?
Answer:
The unknown sides (x) are 6 ft. long
Step-by-step explanation:
Add it all together:
x+x+5+7+10+10+12+14=70
Simplify a little more:
2x+58=70
Subtract 58 from both sides
2x+58 -58=70-58
Solve
2x=12
Divide by 2 on both sides
2/2x=12/2
Solve
x = 6
The unknown sides (x) are 6 ft. long

Find the values of the variables. then find the side lengths of the square.
x = 2, y = 9, and the side length of the square is 6 units.
What is a Square?A square is a quadrilateral that has four equal lengths, that is, all its sides are equal.
Thus:
y - 6 = 2y - 15
Combine like termsy - 2y = 6 - 15
-y = -9
y = 9
Also:
3x - 3 = y - 6
Plug in the value of y3x - 3 = 9 - 6
3x - 3 = 3
3x = 3 + 3
3x = 6
x = 2
Therefore, the sides would be:
y - 6 = 9 - 6 = 3 units
In summary, x = 2, y = 9, and the side length of the square is 6 units.

Answer:
15 units = h
Step-by-step explanation:
formula to find the volume is:
V = (l·w·h) ÷ 3
675 = (9)(15)h ÷ 3
675 = 135h ÷ 3
multiply each side by 3 to get:
2025 = 135h
2025/135 = h
15 = h
You mix 2/3 quart of blue paint for every 3/4 quart of red paint to make 4 quarts of purple paint. How
much blue paint and How much red paint do you use?
Answer:
1.8828 quarts of blue paint
2.1172 quarts of red paint
(check the explanation for more round off variations)
Step-by-step explanation:
Convert both fractions to decimals
[tex]\frac{2}{3}[/tex] = 0.667
[tex]\frac{3}{4}[/tex] = 0.75
Then turn the decimals to percentages
66.7%
75%
Then rewrite it as a fraction to find the missing percentages
75% : 1.417 = x : 1
Solve for x
x = 52.93
Then do this again for 66.7%
66.7% : 1.417 = x : 1
Solve for x
x = 47.07
Then find the values of these percentages relating to 1
47.07% of 1 is 0.4707
52.93% of 1 is 0.5293
Now we have how much blue paint and red paint is in each quart of purple paint
Multiply them by 4 to get the total
0.4707 x 4 = 1.8828
0.5293 x 4 = 2.1172
Now we have:
1.8828 quarts of blue paint
2.1172 quarts of red paint
Now if you want it to be rounded off to the nearest tenths or hundredths
1.8828 = 1.9 (hundredths = 1.88)
2.1172 = 2.1 (hundredths = 2.12)

[tex]8/9 0.9[/tex]
One method which I find easier is converting both into fractions.
8/9 = 8/9 , and 0.9 = 9/10
Now, you have to find the least common denominator, which is 90 (9*10)
Now you have 80/90 and 81/90.
You have finished 80/90.
Your friend has finished 81/90.
81/90 > 80/90 so your friend is correct, they have done more of their project.
Hey im having a hard time understanding input and output and how they correspond with each other
Answer: A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

The center of a circle is located at (2, 3) and has a radius of 6 units. Which equation represents this circle?
A- (x - 2)2 + (y - 3)2 = 6
B-(x - 2)2 + (y - 3)2 = 36
C- (x + 2)2 + (y + 3)2 = 36
D- (x + 2)2 + (y + 3)2 = 6
By using the general equation for a circle, we will see that the correct option is:
(x - 2)^2 + (y - 3)^2 = 36
How to find the equation for a circle?
The general equation for a circle centered at the point (a, b) of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:
(x - 2)^2 + (y - 3)^2 = 6^2
(x - 2)^2 + (y - 3)^2 = 36

The speed of sound varies depending on many factors including temperature, pressure, and humidity, but it is
typically found to be approximately 550 m/s. What is the frequency of a sound wave with a wavelength of 0.2 m?
Answer: Hope this helps
Step-by-step explanation:The equation for finding the frequency of a sound wave given speed and wavelength is:
Speed = Wavelength * Frequency
Therefore, by algebra;
Frequency = Speed / Wavelenght
The given values are:
speed = 330 m/s
wavelength = 0.1 m
Therefore to solve for frequency:
Frequency = (330 m/s) / 0.1 m = 3.3 kHz
Therefore, the frequency of a sound wave at wavelength equals 0.1 m 3.3 kHz.

A cube has a volume of 64. What is the length of one side of the cube?
Answer:
4
Step-by-step explanation:
The volume of a cube can be represented as s^3 = v, where s = side and v = volume. In this case, we're given the volume as 64, so s^3 = 64. To solve this problem, we first have to know what a cube root is.
What's a cube root?
The cube root of a number is the number you multiply by itself 3 times to get another number.One common cube is 27, and the cube root of it is 3 because 3 x 3 x 3 = 27.Given the information above, let's go in order with the list of cube roots to see which one has a cube of 64.
1: 1 x 1 x 1 = 1. 2: 2 x 2 x 2 = 8. 3: 3 x 3 x 3 = 27.4: 4 x 4 x 4 = 64. (This is the cube root!)We found the cube root of 64, or the side of the cube with a volume of 64. The side of the cube, therefore, is 4.
