Is a triangle with sides of length 6ft, 21 ft, 23 ft a right triangle

2 answers:

7 0

According to the pythagorean theorem a^2+b^2=c^2 where c is the largest side. The square root of 6^2+21^2=21.84 which does not equal 23. So it is not a right angle triangle.

Try the Pythagorean theorem, $a^{2} + b^{2}= c^{2}$ . Does $6^{2} + 21^{2} = 23^{2}$ ? If it does, you have yourself a right triangle. If it doesn't, then it isn't a right triangle.

A tree grows 20 percent taller every year after it is planted. The tree was 12 feet tall when planted. How tall will it be after

Lelu [443]

Answer:

Option A; 74.3 feet

Step-by-step explanation:

~ Here we can see that this problem is set to be so that compound interest is applied ~

1. If compound interest is to be applied, it would be that the "20 percent" is the interest, the principle number ( start value ) ⇒ 12 feet in height, and the time is 10 years.

2. Let us approach this problem step by step. Instead of substiting values into a compound interest formula, let us simply attempt a variation of that process...

3. 20 percent is, in a decimal form, ⇒ 0.2

4. Now add 1 to this value 0.2, to get ⇒ 1.2

5. If we were to consider the formula, 1.2 would first be exponentially multiplied by itself 10 time, considering that it is to the power of 10 years. In other words ⇒ 1.2^10 = 6.191736422..........

6. Now let us multiply this infinite value 6.19...... by the principle quantity 12 feet ⇒ 6.191736422.......... * 12 = <em>(About) 74.30083707.......</em>

7. If we were to round this value, it would be to ⇒ 74.3 feet, or in other words the first option; <em>Option A</em>

Please help need to get to 80%

Shalnov [3]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.

Set up a unit converter:

$4\ ft(\frac{12\ in}{1\ ft})$

The ft cancel out leaving us with:

$4*12\ in=48\ in$

Now, we can set up a scale factor...

$\frac{drawing}{real\ length}=\frac{8}{48}=\frac{1}{6}$

mixer [17]

Answer:

Step-by-step explanation:

Respectively we will say the book has One thousand pages (1000) . Now we find 1/4 of a 1000 which is 250 , then we find 1/5 of a 1000 which is 200. Now we add them together which is 250+200=450 . 450 / 1000 = 9/20 which is about a half
