Answer:

the diameter will be D=26 in.

Step-by-step explanation:

The area of a circle is given by:

[tex]A=\pi R^{2}[/tex] (1)

Where:

Now, we know that A = 169 π in²

So, we just need to use equation 1 to find R.

[tex]169\pi = \pi R^{2}[/tex]

[tex]R=\sqrt{169}[/tex]

[tex]R=13 \: in[/tex]

Therefore, the diameter will be D=2*R=26 in.

I hope it helps you!

The diameter of the circle is 26 inches

The area of the circle is given as:

[tex]A = 169\pi[/tex]

The area of a circle is calculated as:

[tex]A = \pi r^2[/tex]

By comparison, we have:

[tex]\pi r^2 = 169\pi[/tex]

Divide both sides of the equation by pi

[tex]r^2 = 169[/tex]

Take the positive square roots of both sides

[tex]r = 13[/tex]

Multiply by 2, to calculate the diameter

[tex]d =2 * 13[/tex]

[tex]d = 26[/tex]

Hence, the diameter of the circle is 26 inches

Answer:

The answer is D, $60 per toy plane.

Answer:

d.) 60$

Step-by-step explanation:

You divide 300$ by 5 and you get 60 dollars per toy plane

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

Answer:

Step-by-step explanation:

So we know that Alex is trying to save $230.

He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.

If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.

38×5= 190

Therefore, Alex will have enough money to buy a tablet in five weeks.

I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

Answer:

33 1/3 %

Step-by-step explanation:

6/9 = 1/3 = 33 1/3 %

Hope that helps!

The 6 is approximately 66.67% of 9.

To calculate what percent 6 is of 9, we can use the following formula:

Percent = (Part / Whole) * 100

In this case, 6 is the part and 9 is the whole. Substituting these values into the formula:

Percent = (6 / 9) * 100

To simplify, we divide 6 by 9:

Percent = (2 / 3) * 100

Multiplying 2/3 by 100:

Percent = (2 * 100) / 3

Percent = 200 / 3

To express the result as a decimal:

Percent ≈ 66.67

Therefore, 6 is approximately 66.67% of 9.
