Answer:
12.81 miles
Step-by-step explanation:
You need to use the Pythagorean Theorem to draw a triangle.
10 squared + 8 squared = c squared.
100 + 64 = c squared
164 = c squared
find the square root of 164:
12.81.
Answer:
x=36
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
Therefore,
x+65+79=180
Add 65 and 79
x+144=180
We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.
x+144-144=180-144
x=180-144
x=36
Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.
x+65+79
We know x is equal to 36, so we can substitute it in
36+65+79
180
The 3 angles add to 180, so we know that x=36
Answer: D the final mean is higher than the original
Step-by-step explanation:
90+85+98+60+84+78/6= 82.5 as the original mean
dropping 60 which is the lowest grade means 90+85+98+84+78/5=87 which means the new mean is 87 which is greater than the original mean of 82.5
So the answer is D
