Answer:
the answer that 3.45 should be as a percent should be 345% because you mutliply 3.45 times 100 getting an answer of 345% and if you want to convert into a mixed number the percent 3 45/100 or simplified to 3 9/20 so hopefully that is the correct answer.
Step-by-step explanation: :DDDDDD hope this helps and mark me brainliest please.
<h2>x = 15°</h2><h2>--------------------------</h2>
<u>Step-by-step explanation:</u>
10 + 5x = 10 + 5(15)
= 10 + 75
= 85°
4x - 10 = 4(15) - 10
= 60 - 10
= 50°
6x - 5 = 6(15) - 5
= 90 - 5
= 85°

So you are asked to find t when the ball hits the ground, so set the equation to 0.
0=65-10t-5t^2
Answer:
Step-by-step explanation:
Our approach here is to isolate X, and simplify this solution. We want to begin by subtracting matrix 2, as shown below, from either side - the first step in isolating X. Afterwards we can multiply either side by the inverse of matrix 1, the co - efficient of X, such that X is now isolated. We can then simplify this value.
Given,
: Matrix 1
: Matrix 2
( Subtract Matrix 2 from either side )
( Simplify )
( Substitute )
( Multiply either side by inverse of Matrix 1 )
- let's say that this is Matrix 3. Our solution would hence be Matrix 3.
7/8 = y/11
so multiply 11 to both sides of the equation
so now its (7*11)/8= y
y=77/8
if decimal then 9.625
hope that helps
