Mathematics

Burka [1]2 years ago

The answer would be 5/8 and 0.625 in decimal form.


1/-4 - 1/2 * 7/-4 (divide then multiply)

1/-4 - 1 * 7 over 2 * -4 (multiply)

1/-4 - 7 over 2 * -4 (simplify 1 * 7 to 7)

1/-4 - 7/-8 (simplify 2 * -4 to -8)

1/-4 - (7/-8) (move the negative sign to the left)

1/-4 + 7/8 (simplify brackets)

5/8 (simplify).

Answer:

46.5

Step-by-step explanation:

Of all straight angles have 180 degrees in them.

So, to find x we need to form this equation:

x + 65 + x - 22 = 180

2x + 43 = 180

2x = 180-43

2x = 137

68.5 degrees = x

68.5-22 = 46.5 degrees.

m<CBD = 46.5 degrees.

m<GBF = also 46.5 degrees because it is a vertical angle to <46.5 degrees.

If f (x) = StartRoot x EndRoot + 12 and g (x) = 2 StartRoot x EndRoot, what is the value of (f – g)(144)
Luda [366]

The value of (f-g)(144) is 0

Step-by-step explanation:

We are given:

f(x)=\sqrt{x}+12\,\,and\,\,\\ g(x)=2\sqrt{x}

We need to find value of (f-g)(144)

We will put x=144 for both f(x) and g(x)

(f-g)(144)=f(144)-g(144)\\=\sqrt{144}+12-(2\sqrt{12})\\=12+12-(2(12)\\=24-24\\=0

So, the value of (f-g)(144) is 0

Anna007 [38]
Side a is 13 when using the pythagorean theorem

a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169
c = 13
