Answer:
y = 25
Step-by-step explanation:
Hey There!
The angle labeled x is supplementary to the angle that is equal to 115 meaning that the sum of the two angles will add up to equal 180
so to find x we subtract 115 from 180
180-115=65 so x = 65
Now we can find y
remember the sum of the triangles angles add up to equal 180
so we subtract the given angles(90 and 65) from 180
180-90-65=25
so y = 25
Answer:
Step-by-step explanation:
"Two times one number added to three times a second number is 21.
2x + 3y = 21
"The second number is ten less than five times the first number"
y = 5x-10
Substitution
2x+3(5x-10) = 21
2x + 15x - 30 = 21
17x = 51
x = 3
y = 5x-10 = 5
Answer:
x= -3

Look at the screenshot, it explains how I got the answer.
Step-by-step explanation:
The outlier is excluded, so the minimum is 59.
Let's think of something that one can hold against a page and draw a circle. Some examples are: a cup, a D battery, a can of soda, the tube from the inside of a paper towel roll, a can of beans, etc.
Think of the can of beans. The part that touches the page (and that you trace around with your pencil) is called a face.What these items have in common is that the faces at the ends are circles (they may or may not be the same size).
The name for this 3-D figure is called a cylinder. Her block, therefore, is a cylinder.
Technically, if the ends were ovals we would still call it a cylinder and so to make sure you have the one with the circles at the ends you would say you have a "right circular cylinder" but for most cases people just say "cylinder" and assume the ends are circles. It really depends what level (elementary, middle school, hs, college) of math you are doing whether just cylinder suffices.
