Answer: 16 minutes
30-27. 28 = 2. 72
2. 72 ÷ 0. 17 = 16
Answer:
Part 1) 
Part 2) The length of the hypotenuse is 6 units
Step-by-step explanation:
Part 1) we know that
In the right triangle of the figure
----> by SOH (opposite side divided by the hypotenuse)
solve for y

Remember that

substitute


Part 2)
Let
h ----> the length of the hypotenuse
we know that
In the right triangle of the figure
----> by SOH (opposite side divided by the hypotenuse)

Remember that

substitute


Answer:
C) 2.5
Step-by-step explanation:
8.8=x*3.5
divide 3.5 on both sides.

Step-by-step explanation:
<u>Step 1: Define Expression</u>
2 × (3³ - 5 + 8)
<u>Step 2: Evaluate</u>
- [Parenthesis] Exponents: 2 × (27 - 5 + 8)
- [Parenthesis] Subtract: 2 × (22 + 8)
- [Parenthesis] Add: 2 × 30
- Multiplication: 60
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
