Answer:
The reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Step-by-step explanation:
We are given the following in the question:
The completion of a chemical reaction is expressed by the equation
where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160
Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Hmm, so they seem to be increaeing by powers of 5
10=2 times 5
25=5 times 5
35=7 times 5
60=12 times 5
so maybe it is
nth term=5(n+2) or 5n+10
lets try it
0th term
5(0)+10
0+10=10
corrrect
3rd term
5(3)+10
15+10
25
correct
so the function is
f(x)=5(x+2)
Answer: 48
Step-by-step explanation:
total of all the degrees of the angles of the triangle is ALWAYS 180
let the measure of angle G be x
180 = 102+30+x
180 = 132+x
x = 48
I think it’s 15 sorry if I’m wrong
To work out the surface area of a triangular prism:
Base: l x w
= 4 x 7
= 28 feet
Top: l x w
= 5 x 7
= 35 feet
Two sides: 1/2 x b x h
= 1/2 x 4 x 3
= 6 + 6 (for the other side)
= 12 feet
Left side: l x w
= 3 x 7
= 21
Add all of them up:
= 28 + 35 + 12 + 21
= 96 square feet
