Answer:
x = 34
Step-by-step explanation:
90° + 42° = 132°
180° - 132° = 48°
m∠DFE = 48°
2x + 48 + 64 = 180
2x + 112 = 180
2x = 68
x = 34
Answer:
FIrst, lets set up some rules to keep in mind:
The interior angles of any triangle will add up to 180°
Therefore, m<FED + m<FDE + m<DEF or in other words 64 + 2x+ m<DFE=180
Next, lets note that there are supplementary angles in this problem which are a set of angles that add to 180°. For example, m<HFC + m<EFH + m<DFE = 180.
With those in mind lets solve:
If we find the m<DFE then we can find the value of x since the interior angles of any triangle add to 180.
to find f we can use supplementary angles.
42°+90°+m<DFE=180
132+m<DFE=180
m<DFE=48°
Therefore,
64+48+2x=180
112+2x=180
2x=68
x=34
To check our answer we can plug in 34 for x and the 3 interior angles of that triangle should add to 180
2(34)+64+48=180?
68+64+48=180?
180=180
x=34 is valid

Find the volume of a hemisphere with a radius of 8. Round to the nearest tenth.
Answers
Answer:
V(hemisphere) = 1072.3in^3
Step-by-step explanation:
To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.
The volume of a sphere is:
Let's plug in the radium of 8 into the equation and solve:
Now, divide it by 2
V(sphere) = (2144.660585)/2
V(hemisphere) = 1072.3in^3

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?
Answers
With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.
Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.
Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.
I hope that helps, have a great rest of your day! ^ ^

Answers
Answer:
Solution
First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.
D={2,3,4,5,6}
Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.
The second coordinate in an ordered pair is the output value. The range is the collection of the ordered pairs' second coordinates. Never list the same output more than once.
What is a domain?The domain of the function is defined as the set of all the possible values of the function. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Determine the input values first. The first coordinate in an ordered pair makes up the input value. Since the ordered pairs are just listed, there are no restrictions. The set of the ordered pairs' initial coordinates is known as the domain.
D={2,3,4,5,6}
Next, identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs. Do not list the same output twice.

(look below)
The number of gallons of white paint mixed with 1 gallon of blue paint is ______.
--I think it could be 4, but it already says 2 gallons of blue paint equals 4 gallons of white paint, so maybe 2...?
Answers
Answer:
2
Step-by-step explanation:
because it is 2 parts white paint one part blue paint
The number of gallons of white paint mixed with 1 gallon of blue paint is 2.
The graph shows the number of gallons of white paint mixed with gallons of blue paint in different ratios.
It is given that 2 gallons of blue paint can be mixed with 4 gallons of white paint.
Since 2 gallons of blue paint can be mixed with 4 gallons of white paint, we can divide both sides by 2 to find the ratio of white paint to blue paint when using 1 gallon of blue paint.
2 gallons of blue paint / 2 = 4 gallons of white paint / 2
1 gallon of blue paint equals 2 gallons of white paint.
So, the number of gallons of white paint mixed with 1 gallon of blue paint is 2.

What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
When you multiply any number by 1, the product is always the same as the original number.
For example, 5 times 1 is 5, and 100 times 1 is 100.
So 1 is known as the multiplicative identity because it has the special property that when it is multiplied by any number, the result is always the same as that number.
