0.40% of a number is 68
40% of n = 68

40% = \frac{40}{100} = 0.4

0.4 × n = 68

\frac{0.4n}{0.4} = \frac{68}{0.4}
n = 170

40% of 170 is 68

0.4 * x = 68
x = 68/0.4
x = 170

check:

0.4 * 170 = 68

Hey i know this question is linked to Pythagorean theorem but i am still confused. So, please help me if you can ❤️
antiseptic1488 [7]

Step-by-step explanation:

From Pythagorean theorem, one of the sides can be determined as x^2 + y^2 =8^2

or y = (8^2 - x^2)^(1/2)

we can write the perimeter P as

P = 2x + 2y ---> 20 = 2x + 2(8^2 - x^2)^(1/2)

Dividing by 2, we get

10 = x + (8^2 - x^2)^(1/2)

Move the x to the other side,

10 - x = (8^2 - x^2)^(1/2)

Take the square of both sides to get rid of the radical sign:

(10 - x)^2 = 8^2 - x^2

Move everything to the left and expand the quantity inside the parenthesis:

x^2 + (100 - 20x + x^2) - 64 = 0

2x^2 - 20x + 64 = 0

or

x^2 - 10x + 32 = 0

Now we can see that a = -10 and b = 32

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain
Harrizon [31]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.

Solve for x: −4x+6(6−2x)=−7x−36
ValentinkaMS [17]

Answer:

x = 8

Step-by-step explanation:

-4x + 6(6 - 2x) = -7x - 36

-4x + 36 - 12x = -7x - 36

-16x + 36 = -7x - 36

<u>       +36           +36</u>

-16x + 72 = -7x

<u>+16x           +16x</u>

72 = 9x

divide by 9

<u><em>x = 8</em></u>
