Given: d=6, l=25, w=15

need to find areas of all surfaces but the top because its a pool and the top is exposed:

2ld + 2dw + lw
2(25)(6) + 2(6)(15) + (25)(15) =
300 + 180 + 375 = 855 ft²

you need to paint 855ft² of interior surface of the pool. the question asked how much paint is needed though, so there is not enough info provided to answer that. once you know how much paint covers 1ft² then you can multiply by 855.

2 wide walls (15x6)x2=180 square feet
2 long walls (25x6)x2=300 square feet
ground 25x15=375 square feet

sum them all up and you get
375+300+180=855

you need paint for 855 square feet

Imagine that you need to compute e^0.4 but you have no calculator or other aid to enable you to compute it exactly, only paper a

labwork [276]

Answer:

0.0032

Step-by-step explanation:

We need to compute $e^{0.4}$ by the help of third-degree Taylor polynomial that is expanded around at x = 0.

Given :

$e^{0.4}$ < e < 3

Therefore, the Taylor's Error Bound formula is given by :

$|\text{Error}| \leq \frac{M}{(N+1)!} |x-a|^{N+1}$ , where $M=|F^{N+1}(x)|$

$\leq \frac{3}{(3+1)!} |-0.4|^4$

$\leq \frac{3}{24} \times (0.4)^4$

$\leq 0.0032$

Therefore, |Error| ≤ 0.0032

I was sick the day that the class went over how to do this and I don’t know how to do it.

You first need to know the equation A=pi x r^2. The equation you need for this problem is pi (3.14) x 3^2

Elsie pays $8.99 for a one-pound canister of Georgia pecans. Write and solve a proportion to determine the cost of 4

ch4aika [34]

Answer:

$ 35.96

Step-by-step explanation:

Let x be the cost ( in dollars ) of 4 ounces of the pecans,

So, the ratio of the cost and ounces needed = $\frac{x}{4}$

Also, the cost of 1 ounces of pecans is $ 8.99,

Thus, the ratio of the cost and ounces needed = $\frac{8.99}{1}$

Hence, we can write,

$\frac{x}{4}=\frac{8.99}{1}$

Which is the required proportion,

By cross multiplication,

x = 4 × 8.99 = 35.96

Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
