Answer:

the answer is 2.87

Step-by-step explanation:

use the pythagorean theorem

2^2+b^2=4^2

that goes to b= 3.5

for the triangle with x you also need to use the pythagorean theorem

$2^{2}$ + $x^{2}$ = $3.5^{2}$

4+ $x^{2}$ =12.25

subtract 4 on both sides

$x^{2}$ =8.25

$\sqrt{x}$ = $\sqrt{8.25}$

x=2.87

Find all real and complex roots of the equation below x^4-81=0

Pepsi [2]

$x^4-81=0 \\ (x^2-9)(x^2+9)=0\\ (x-3)(x+3)(x^2+9)=0\\ x=3 \vee x=-3 \vee x=3i \vee x=-3i$

Sam has 8 quarters, 5 dimes, and 3 Nicole's in his pocket. If one coin is selected random, what is the probability that it will

Murrr4er [49]

There are a total of 16 coins, so out of the ratio, that 16 goes on the bottom. Now you have to add up the coins that are NOT quarters and that number goes on the top. So your ratio is 8/16 or 1/2

A Triangle has an area of 36cm^2. The base and height are scaled by a factor of 5. What is the area of the resulting triangle?

Finger [1]

Answer:

Area of resulting triangle will be 900 $cm^2$ .

Step-by-step explanation:

When sides of any polygon if scaled by a factor of k

then area is scaled by $k^2$

According to the above statement

therefore here in the question since area of original triangle was 36 $cm^2$

and both base and height are scaled by a factor of 5.

therefore area of scaled triangle will be $5^2$ times of the original

that is 25 x 36 which gives 900 $cm^2$

So area of resulting triangle will be 900 $cm^2$
