Step-by-step explanation:

The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.

Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.

aleksley [76]

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.





PS i wouldn't recommend doing a 2 km swim fly and breast

Which ordered pair is the solution to the system of linear equations y = -7x + 2 and y = 9x - 14?
lisabon 2012 [21]
Y = -7x + 2
y = 9x - 14

-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x

y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5

solution is : (1,-5) <==

If G = {(-1, 7),(-8, 2),(0, 0),(6, 6)), then the range of G is
lana66690 [7]

Answer:

\{0, 2, 6, 7\}

Step-by-step explanation:

You are given the relation G = \{(-1, 7),(-8, 2),(0, 0),(6, 6)\}

This means that

f(-1)=7\\ f(-8)=0\\f(0)=0\\f(6)=6

The input values of this relation are -1,\ -8,\ 0,\ 6, so the domain of this relation is \{-8,-1,0,6\}

The output values of this relation are 7,\ 2,\ 0,\ 6, so the range of this relation is \{0, 2, 6, 7\}
