Jason started his project at 2:30 p.m and finished 2 hours and 15 minutes later . He spent 25 minutes doing research, 30 minutes writing a report and the rest of the time building a model. What time did he finish his project? How much time did he spend building the model?
Answers
2 hrs and 15 minutes later
=
4:45
2:30
+ 30
=
3:30
+ 25
= 3:55
4:45 - 3:55
= 50 minutes
He finished his project at 4:45.
He spent 50 minutes building the model.

Step By Step - add all the numbers in the triangle together then subtract that number by 180
Answer:
x=65
Step-by-step explanation:
In a triangle the three inside angles added together always equal 180. So 73+51+21+x=180
51+21+x=107
21+x=86
x=65

Answer:
the ball hit the ground at
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward
The vertex is a maximum
we know that
The x-intercept of the function is the value of t when the value of h(t) is equal to zero
The ball hit the ground when h(t) is equal to zero
equate the function to zero and solve for t
Factor the leading coefficient
The solutions are
therefore
the ball hit the ground at
When the ball hits the groung h(t) = 0
Then solve the equation for t
- 16t^2 + 96 t = 0
Divide by -16
t^2 - 6t = 0
t(t-6) = 0
t =0 is when the ball is kicked off
t = 6 is the answer.

volume of sphere=4/3pi times r^3
volume of earuth
4/3 times pi times 6371^3=aprox 1.08 times 10^12 (really big number so scientific notation)
volume of pluto
4/3 times pi times 1161^3=6.56 times 10^9
so pluto times x=earht
divide both sdies by pluto
x=earth/pluto
solve for x
earth=1.08 times 10^12
pluto=6.56 times 10^9
(1.08 times 10^12)/(6.56 times 10^9)=(1.08/6.56) times (10^12)/(10^9)
when dividing exponents, just subtract
12-9=3
so
1.08/6.56 times 10^3
0.164634 times 10^3
164.634
