The value of c is equal to _____.

Mathematics
1 answer:
DENIUS [597]4 years ago
8 0

For this case we have that by definition, the Pythagorean theorem states that:

c = \sqrt {a ^ 2 + b ^ 2}

Where:

a, b: Are the legs

c: It is the hypotenuse

According to the figure we have to:

a = 20\\b = 21

Substituting in the formula we have:

c = \sqrt {(20) ^ 2 + (21) ^ 2}\\c = \sqrt {400 + 441}\\c = \sqrt {841}\\c = 29

Answer:

Option D

) Which statements about -3 and -7 are true? Choose ALL the correct answers.
trasher [3.6K]

Answer: -3 is greater than -7 and the absolute value of -3 is less than the absolute value of -7.

Step-by-step explanation:

For NEGATIVE numbers, the closer the value is to 0, the greater it is. -3 is closer to 0 than -7 is, so -3 is greater than -7. For POSITIVE numbers, the further away the number is from 0, the greater it is. The absolute value of -3 is 3 and the absolute value of -7 is 7, and 7 is farther away from 0 than 3 is. So, the absolute value of -3 is less than the absolute value of -7. Hope this helps!

The difference of twice a number and five is three. Find the num
Grace [21]

Answer:

add 5 then multiply by 1/2

Step-by-step explanation:

Twice a number  is 2n.

The difference of twice a number and five 2n - 5.

The difference of twice a number and five is three. 2n - 5 = 3

2n - 5 = 3

2n - 5 + 5 = 3 + 5     (1) add 5

2n = 8

1/2*2n = 1/2*8    (2) multiply by 1/2

n = 4

8.6.PS-14
s2008m [1.1K]

Answer:

Answer:

11 feet

Step-by-step explanation:

Area formed by the watery pattern is 379.94 square feet.

Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.

Area of a circle is given as:

\begin{gathered}Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11\end{gathered}

Area=πr

2

379.94=πr

2

r

2

=

π

379.94

Using pi equal to 3.14, we get

r

2

=121

r=11

This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.

Step-by-step explanation:

im not sure if that is correct

comment if wrong

*hope it help:))
