B. 40 is 160% of what number?

Mathematics
1 answer:
Anton [14]2 years ago
6 0

Answer:

25

Step-by-step explanation:

the question basically translates to

160% x n =40  

a little trick with percents I use is that the word "of" always means multiplication.

n=40/160%=25

180 = 96 + 2x + x + 12

180 = 96 + 3x + 12

180 = 108 + 3x

-108  -108

72   =  3x

24 = x

Can someone help me with this question please. I'll give the brainliest answer to whoever helps me.
Doss [256]

Answer: \sqrt[5]{y}

I realize its probably not the largest readable font. If you are having trouble reading it, it is the square root of y; however, there is a tiny little 5 in the upper left corner to indicate a fifth root. So you would read it out as "the fifth root of y"

The rule I'm using is

x^{1/n} = \sqrt[n]{x}

and the more general rule we could use is

x^{m/n} = \sqrt[n]{x^m}

where m = 1. This rule helps convert from rational exponent form (aka fractional exponents) to radical form.

Which expressions are algebraically equivalent to the correct usage of the distance formula to find the distance from point A(3,
egoroff_w [7]

Answer:

(5)

Step-by-step explanation:

The given two points are:

A(3,k) and B(h,4)

Now, using the distance formula that is=\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}.

In the given points, y_{2}=4,y_{1}=k,x_{2}=h and x_{1}=3, thus,

\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}=\sqrt{(4-k)^{2}+(h-3)^{2}}

which is the required equation, hence option 5 is correct.

Enter the degree form for 3π/4 radians in the box.
Paraphin [41]

Answer:

135 degrees

Step-by-step explanation:

2π radians is the central angle of a full circle, so 2π radians is 360 degrees.

That means that π radians = 180 degrees.

3π/4 radians * (180 degrees)/(π radians) = 135 degrees
