Answer:
The answer to your question is It will take 1 hour to find Marissa
Step-by-step explanation:
Data
Marissa time = 7:00 am speed = 12 mi/h
Roommate time = 7:30 am speed = 18 mi/h
Process
1.- Calculate the distance traveled by Marissa in 30 min (0.5 h)
d = vt
d = (12)(0.5)
d = 6 mi
2.- Write an equation to solve this problem
Distance traveled by Marissa = Distance traveled by the roommate
6 + vmt = vrt
- Substitution
6 + 12t = 18t
- Solve for t
6 = 18t - 12t
6 = 6t
t = 6/6
t = 1 h
That would mean 6 is 3 times the original price, 6 is divisible by 3 so it is possible and the price would be 2.00
Hope this helps :)
Answer:
A = 70 mm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 10, b₁ = 10, b₂ = 4 , then
A =
× 10 × (10 + 4) = 5 × 14 = 70 mm²
Test each one out! Coordinates are written in (x, y) so just substitute each one
A) 3(1)+2(4) = 11
B) 3(2)+2(3) = 12
C) 3(3)+2(1) = 11
D) 3(4)+2(-1) = 10
Out of all these answers B has a value less than 12 so the answer is:
B (2,3)
