Answer:

$49.55

Step-by-step explanation:

Firstly, we multiply how much money you receive per week by the amount of weeks saved. This means, $5.25 * 12, or $63.

Now, we subtract $63 - $13.45, the amount spent, which equals $49.55.

<u>This means that option B is correct, you would have $49.55 dollars left</u>

Step-by-step explanation:

Using the solution diagram attached below :

The difference in height of the two buildings :

Building B - Building A = (654 - 480) = 174 feets

Using trigonometry :

Cosθ = opposite / Adjacent

Cos 42 = d / 174

d = 174 * Cos 42

d = 129.307

A lumber company needs to estimate the volume of wood a load of timber will produce. The supervisor knows that the volume of woo

Hitman42 [59]

Answer with Step-by-step explanation:

Let the volume be represented by 'V'

Since it is given that Volume varies with height 'h' and square of the girth 'g' we can write

$V=khg^2$ where 'k' is a constant of proportionality

Now it is given that volume is 288 cubic meters for h= 40 meters and g =1.5 meters we can write

$288=k\times 40\times 1.5^2\\\\\therefore k=\frac{288}{40\times 1.5^{2}}=3.2$

Thus the volume of the timber as a relation is

$V=3.2\times hg^{2}$

Part b)

Volume of 50 trees with height 75 meters and girth 2 meters is

$V=50\times 3.2\times 75\times 2^{2}\\\\\therefore V=48000m^{3}$
