Answer:

468 square feet.

Explanation:

The lateral surface of the foam pit can be calculated as:

Lateral Surface = Perimeter Base x Height

So, the perimeter of the base can be calculated as:

Perimeter = 12 ft + 24 ft + 12 ft + 24 ft

Perimeter = 72 ft

Therefore, the lateral surface is equal to:

Lateral surface = 72 ft x 6.5 ft

Lateral surface = 468 ft²

Then, 468 square feet will be painted red.

If c(x)=4x-2 and d(x)=x^2+5 , what is (c o d) (x)

Nookie1986 [14]

Answer:

4x² + 18

Step-by-step explanation:

note that (c ○ d )(x) = c(d(x))

To evaluate substitute x = d(x) into c(x), that is

c(d(x))

= c(x² + 5)

= 4(x² + 5) - 2

= 4x² + 20 - 2

= 4x² + 18

Sports American football fields measure 100 yards long between the end zones, and are 53 1_3yards wide. Is the length of the dia

Ann [662]

Answer:

$113 \frac{1}{3}$ Yards

Step-by-step explanation:

solving using Pythagorean Theorem

$a^2+b^2=c^2$

$100^2+53.33^2 = c^2$

$10,000+2844.0889=c^2$

$12844.1=c^2$ square root

= $113 \frac{1}{3}$

Base on the explanation above we can tell that the length of the diagonal across this field is less than 120 yards.

Evaluate the statistics expression:39C1

Aleksandr-060686 [28]

<h3>Answer: 39</h3>

========================================================

Explanation:

You can use the nCr formula shown below

$_n C _r = \frac{n!}{r!*(n-r)!}$

where n = 39 and r = 1. However, you could also use the identity

$_n C _{1} = n$

which basically says there are n ways to pick 1 item if you are given a choice of n items. In this specific case, we have 39 items total, and there are 39 ways to pick one item.

How to graph {3x-8y = 29

labwork [276]

<span>How to graph {3x-8y = 29 3x+y = -2}
</span> The first thing you should do is to clear "y". Then, you must substitute values of x in the equation to find the values of "y". Finally, graph the points obtained. (see graphic)
How do you convert this to slope intercept form? 3x-8y = 29 ---> y = 0.375x - 3.625 3x+y = -2 ---> y = -3x - 2

The sun produces 3.9 ⋅ 10 to the 33th power ergs of radiant energy per second. How many ergs of radiant energy does the sun prod

arlik [135]

So the sun produces 3.9x10³³/ second

Using this ratio (3.9x10³³/ second) we can use the porpotions to calculate time taken (T) to produce 1.55x10⁷.

$\frac{3.9(10^3) ergs}{1 second} = \frac{1.55(10^7)ergs}{T}$

Then isolate T and find the time

$\frac{T3.9(10^3)ergs}{1 second} = {1.55(10^7)ergs$
$T3.9(10^3)ergs = ({1.55(10^7)ergs)seconds$
$T = \frac{(1.55(10^7)ergs)seconds}{3.9(10^3)ergs}$
$T = \frac{(1.55(10^7)seconds}{3.9(10^3)}$
$T = \frac{1.55}{3.9}(10^4)seconds$
$T = 0.397(10^4)seconds$
$T = 3.97(10^-^1)(10^4)seconds$
$T = 3.97(10^3)seconds$

Thus it took 3.97x10³ seconds for 1.55x10⁷. of ergs to be produced
Hope that helped and if it did, a Brainliest rating would be much appreciated
