Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
Answer:
Length of truck = 160 +7% of 160 = 160 +11.2 = 171.2inches
I hope this helps! It’s been a while since I’ve done slope-intercept though, so I might be a little rusty
Answer:
1.5 times per second
(1 time per second if rounded to a whole number)
Step-by-step explanation:
1 minuet is equal to 60 seconds
Because you are given 88 vibrations in one minute, you will divide 88 by 60 seconds. You want your answer in seconds.
88/60 gives us 1.466666667 on a calculator
So the guitar gives a vibration of 1.466666667 per second
If we round this, we get 1.5 vibrations per second
Or, if we round 1.4666 to a whole number then it is 1 vibration per second
