Answer: c.

Step-by-step explanation:

A= .5*b*h

A = .5* $\sqrt{5} * \sqrt{10}$

A = 3.5355339059

5/ $\sqrt{2}$ <em> = </em> 3.5355339059

What is the approximate radius of a sphere with a volume of 1436cm to power of 3

Margarita [4]

Answer:

<h3>The radius is 7 cm</h3>

Step-by-step explanation:

Volume of a sphere is given by

$V = \frac{4}{3} \pi {r}^{3}$

where r is the radius

From the question V = 1436 cm³

$1436 = \frac{4}{3} \pi {r}^{3}$

Multiply through by 3

We have

$4308 = 4\pi {r}^{3}$

Divide both sides by 4π

${r}^{3} = \frac{4308}{4\pi}$

${r}^{ 3} = \frac{1077}{\pi}$

Find the cube root of both sides

$r = \sqrt[3]{ \frac{1077}{\pi} }$

r = 6.99

We have the final answer as

Hope this helps

We have a box with eight green marbles, five red marbles, and seven blue marbles. We choose three marbles from the box at random

Salsk061 [2.6K]

Answer: 0.089

Step-by-step explanation:

Number of combinations of n things taking r at a time :-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

Given : A box has eight green marbles, five red marbles, and seven blue marbles.

Total marbles = 5+8+7=20

We choose three marbles from the box at random without looking.

Number of ways to choose 3 marbles with same color :-

$^8C_3+\ ^5C_3+ ^7C_3\\\\=\dfrac{8!}{3!(8-3)!}+\dfrac{5!}{3!(5-3)!}+\dfrac{7!}{3!(7-3)!}\\\\=56+10+35=101$ (1)

Total ways to select 3 marbles from 20 marbles :-

$\dfrac{20!}{3!(20-3)!}=1140$ (2)

Now, the required probability (divide (1) by (2)):-

$\dfrac{101}{1140}=0.0885964912281\approx0.089$

Hence, the required probability : 0.089

(1.3t3 + 0.4t2 – 24t) – (0.6t2 + 8 – 18t)

lorasvet [3.4K]

To solve this problem you must apply the proccedure shown below:
1. You have that the the polynomial being subtracted is 0.6t²+8-18t, therefore, <span> to find the additive inverse of the polynomial, you must multiply it by -1, as following:
</span>(0.6t²+8-18t)
(-1)(0.6t²+8-18t)
2. Therefore, you obtain the following result:
-0.6t²-8+18t
Then, tas you can see, the answer is -0.6t²-8+18t.

The Saxena family plans to install a light to illuminate part of their rectangular yard. Nikki and Dylan each proposed a differe

seropon [69]

The correct situation for the given condition are as follows:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.

<h3>What is Area of Triangle?</h3>

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

The area of a triangle = (base x height) / 2

and,

both lights illuminate the same base and height = (60 x 38) / 2

= 1,140 sq ft

Both Dylan's and Nikki's proposed placement will lit exactly half of the yard.

The yard's total area = 60 x 38 = 2,280 sq ft,

which is twice the area lit by the lights.

Thus, The correct situation for the given condition are as follows:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.
