nadya68 [22]

Answer:

Part 1) V=343\ km^{3}

Part 2) V=1,331\ yd^{3}

Step-by-step explanation:

The volume of a cube is equal to

V=s^{3}

where

s is the length of the cube

Part 1)

we have

s=7\ km

substitute in the formula

V=7^{3}

V=343\ km^{3}

Part 2)

we have

s=11\ yd

substitute in the formula

V=11^{3}

V=1,331\ yd^{3}

An airplane flies 810 km in 1.5 hours. How far will the plane fly into. Two hours if it maintains the same airspeed
nadezda [96]

It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:

810/1.5 = 540 km/hour

Then, multiply both the hour and the distance by 2:

540 * 2 = 1080 km/2 hours.

Which graph would help you find the solutions of 2 – x2 = –x?
Lelechka [254]

Step-by-step explanation:

A quadratic graph will surely help you find the solutions

X2-x-2=0

x1=2 x2= -1

Substitute each of the x value in the original equation to get the y value

(2)^2-(2)-2= 0 (2,0)

(-1)^2-(-1)-2=-2 (-1,-2)

plot the coordinates on the graph,the graph should be a curve
