Answer:
295 mi
Step-by-step explanation:
we can write this as an equation. the base fee, with no miles traveled is 25. this will be our y intercept, or b in the equation y = mx + b
our slope is .4
for every 1 mile increase for x, our y increases by .4
so:
y = .4x + 25
set this equal to 143.40
143.40 = .4x + 25
x = 295 mi
The answer I got is (2x^2+x-15)
Answer:
B) 9 gallons
Step-by-step explanation:
It's asking you what 3/4ths of 12 is. Therefore, you multiply 3/4 by 12 to get your answer which is 9 gallons.
Answer:
lateral area = 2320 m²
Step-by-step explanation:
The question wants us to calculate the lateral area of a square base pyramid. The square base pyramid has a side of 40 meters.The height is 21 meters.
Half of the square base is 40/2 = 20 meters . With the height it forms a right angle triangle. The hypotenuse side is the slant height of the pyramid.
Using Pythagoras's theorem
c² = a² + b²
c² = 20² + 21²
c² = 400 + 441
c² = 841
square root both sides
c = √841
c = 29 meters
The slant height of the pyramid is 29 meters.
The pyramid has four sided triangle. The lateral area is 4 multiply by the area of one triangle.
area of triangle = 1/2 × base × height
base = 40 meters
height = 29 meters
area = 1/2 × 40 × 29
area = 580
area of one triangle = 580 m²
Lateral area = 4(580)
lateral area = 2320 m²
