We already solve for the B or area of the triangular base which was 5.25cm².
There are 2 triangular faces in the prism so 5.25cm² x 2 = 10.50cm²
There are 3 rectangular face in the prism, we need to get the area of each.
area of a rectangle = length x width
rectangle 1: 5 cm x 4 cm = 20 cm²
same dimension with rectangle 2. so, area is 20 cm² also
rectangle 3: 5 cm x 2.8 cm = 14 cm²
let us all add up the area of each surface.
2 triangle = 10.50 cm²
3 rectangles = 20 cm² + 20 cm² + 14 cm² = 54 cm²
10.50 cm² + 54 cm² = 64.50 cm²
Answer:
-p+78x+39
Step-by-step explanation:
Since the car costs $117 a day and you are going on a three day road trip, then you would do 117 x 3 = 351.
Subtract 351 from the total cost 373 - 351 = 22
To find out how many additional miles you drove, 22/0.22 = 100
So you drove 100 additional miles.
(2x^3+9x)-(4x^2-15x+7)
(8x+9x)-(16x-15x+7)
(17x)-(1x+7)
16x+7
Answer: 61.25m
Step-by-step explanation:
To solve this, the formula used will be:
h = -16t^2 + vt + h(o)
where,
Initial velocity, v = 60mph
Height, h = 5 feet
t = ?
After solving for t, we get t = 1.875 seconds. We then slot it back into the equation.
h = -16t^2 + vt + h(o)
h = -16(1.875)^2 + 60(1.875) + 5
h = -56.25 + 1112.5 + 5
h = 61.25m
