Answer:

A.factor out a GCF

F.factor by grouping

Answer:6060 foot-pounds

Step-by-step explanation:

Given

Weight of cable(w')=0.6 pound per foot

depth of well=60 foot

weight of wrench=7 Pound

Now work done in raising monkey with wrench $=w\cdot h$

$W_1=(80+7)\cdot 60=5220$ foot-pounds

Now work done in raising rope

robot rises by climbing up the cable with one end of the cable still attached thus robot support half the weight of cable so work done

$W_2==\int_{0}^{60}\frac{w'}{2}xdx$

$W_2=0.3\times 0.5\times (x^2)_0^{60}$

$W_2=540$ foot-pounds

$W_{net}=5220+540=6060$ foot-pounds

Find the area of the triangle, also am I correct???

Ierofanga [76]

Answer:

The area of the triangle is 10.92 cm².

Step-by-step explanation:

The formula for the area of a triangle is

$A=\frac{1}{2}bh$

where b is the length of the base and h is the height. We know that b = 2.8 and h = 7.8, so you would substitute into the formula:

$A=\frac{1}{2}(2.8)(7.8)=10.92$ cm²
