Keeli was asked to approximate the square root of 38 to the nearest whole number.

We know that 36<38<64

so sqrt36 < sqrt 38 < sqrt 64 it is equivalent to 6< sqrt38 < 8

since 38 is closer to 36 than it is to 64, so 6 is approximate the square root of 38 as a whole number

3y-y+8-2=20 combine like terms and solve

Flauer [41]

3y - y + 8 - 2 = 20
3y - y = 2y
8 - 2 = 6
2y + 6 = 20
2y = 20 - 6
y = 10 - 3
the answer is: y = 7

Step-by-step explanation:

$\frac{2a}{a + b - c} = \frac{2b}{b + c - a} = \frac{2c}{a + c - b} = k \\ \\ by \: theorem \: on \: equal \: ratios \\ \\ \frac{2a + 2b + 2c}{a + b - c + b + c - a + a + c - b} = k \\ \\ \frac{2(a + b + c)}{a + b + c} = k \\ \\ \therefore \: k = 2$

In 1945, an organization asked 1467 randomly sampled American citizens, "Do you think we can develop a way to protect ourselve

patriot [66]

Yes.

1467-776=691

Which means 776 believed the country was protected and 691 believed the country wasn't.

If m(x) = x+5/x-1, and n(x) = x-3, which function has the same domain as m of n of x?

mamaluj [8]

Is that the exact question? because the last part doesn't really make sense to me

Given that <img src="https://tex.z-dn.net/?f=2%20%7B%7D%5E%7Bx%7D%20%20%3D%200.125" id="TexFormula1" title="2 {}^{x} = 0.12

Luda [366]

Take the natural log of both sides

ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3

ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative
