Answer:
205°
T(t) = 65°+20°t
Step-by-step explanation:
Let the temperature be T and time be t
<u>The equation to determine the temperature T after t minutes is:</u>
<u>For t = 7 we get:</u>
- T(7) = 65° + 20°*7 = 65° + 140° = 205°
Answer:
8
Step-by-step explanation:
4/13 x/26
4 times 26, the that number divided by 4. Its called the butterfly/cross multiplying method
Answer:
A=259.43
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r=R/100
r=2.5/100
r=0.025 rate per year,
then solve the equation for A
A=P(1+r/n)
A=250.00(1+0.025/1)
A=250.00(1+0.025)
A=$259.43
Refer to the diagram below for the sketch of the position of the mirror, Michelle, and the flagpole.
Using similar triangle concept, to find the height of the flagpole, we first need to find out the scale factor of the horizontal distance.
We write this as ratio
Mirror to Michelle : Mirror to Flagpole
12ft : 48ft
1 : 4
So the ratio of the height is
Michelle : Flagpole
1 : 4
5ft : 20ft
