Are the ratios 5:3 and 15:12 equivalent? Justify your answer?

1 answer:

5 0

No, if you do something to one side you do to the other. So 3 times 4 is 12 and 5 times 4 is not 15. I hope that makes sense

Step-by-step explanation:

2^3 X 3^-4 X 5^2 / (2x5)^2 X 2 X 3^2 X 3^-6

I will simply the expression on the RHS if the bracket first

2^2 X 5^2 X 2 X 3^2 X 3^-6

= 2^3 X 3^-4 X 5^2

So, putting them together

Both sides have th same expression

They cancel out each other

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

ryzh [129]

Answer:

The area of the clock $= 315.41\ inch^{2}$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}$

So the area of the face of the clock = $315.41\ in^{2}$

Answer:

Step-by-step explanation:

g(4)=4^2 =16, so we need to find f(16).

f(16)=16-7=<u>9</u>

Answer: See the picture attached.

Step-by-step explanation:

Given the following mixed numbers:

$-2\frac{3}{4}\\\\-4\frac{1}{2}$

You need to convert them to decimal numbers. The steps to do this are shown below:

1. Divide the numerator of the fraction by the denominator.

2. Add the quotient obtained to the whole number part.

Then:

$-2\frac{3}{4}=-(2+0.75)=-(2.75)=-2.75\\\\-4\frac{1}{2}=-(4+0.5)=-(4.5)=-4.5$

Therefore, the point is:

$(-2.75,-4.5)$

Where $-2.75$ is the x-coordinate and $-4.5$ is the y-coordinate.

Knowing this, you can plot it on the coordinate plane, as you can see in the picture attached.
