Answer:

x=196

Step-by-step explanation:

In order to solve this you just have to clear X fro the equation and solve:

$2\sqrt{x} - 5=2\\ 2\sqrt{x}=2+5\\\sqrt{x}=7*2\\x=14^2\\x=196$ Once you´ve calculated this you have the solution for the equation, that is x.

It is not an extraneous solution.

105 degrees

Step-by-step explanation:

Angle DEF measures 75°.Triangle DEF is an isosceles, so AngleDEF Is-congruent-toAngleDFE.

the angles all together is 180 degrees

What is the volume of the cylinder? Round your answer to the nearest whole number??

andreyandreev [35.5K]

Answer:

141

Step-by-step explanation:

1. The volume of a cylinder is $\pi r^2h$ , where r = radius and h = height. In this case, the height is 5 feet and the radius is 3 feet.

Solving Volume

Step 1: Plug in values

$\pi * 3^2 * 5$

Step 2: Simplify.

$3.14 * 9 * 5$
$28.26 * 5$
$141.3$
141.3 ≈ 141

Therefore, the volume of the cylinder is 141 ft^3 (but don't put ft^3, as mentioned in the problem).

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:12,376

Step-by-step explanation:

Given

Connie has 17 Pairs of jeans

She has to choose 6 pairs out of 17

We know, no of ways to pick r items out of n items is $^nC_r$

$\therefore \text{No of ways is =}^{17}C_6\\\\\Rightarrow \dfrac{17!}{(17-6)!6!}=12,376\ \text{ways}$
