A drawing is 14 inches tall and 5 inches wide what is 1/4 of that

14/4 = 7/2
5/4 cannot be simplified any further.
I wasn't sure if this was what you were asking but from the little information that you've supplied, I'm guessing you're asking for 1/4 of the parameters.

14x5=70
70/4=17.5
17.5 is 1/4 of the area of the drawing

The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie

andrey2020 [161]

Answer:

The answer is $25\pi$ units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

The distance between the $x$ 's is 9-3=6.

The distance between the $y$ 's is 9-1=8.

The distance between the points is given by $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$ .

The radius is therefore $\frac{10}{2}=5$ .

We are asked to find the area of this circle.

The formula for finding the area of a circle is $\pi r^2$ .

Since the radius is $5$ , then the area in terms of $\pi$ ,(pi), is $\pi (5)^2=\pi (25)$ .

The answer is $25\pi$ units squared.

I appreciate all the help guys! Need help on this one y’all

You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.

90/60 = 1.5

90 minutes = 1.5 hours

speed = distance/time = (105 miles)/(1.5 hours) = 70 mph

A surveyor measures the length of a surveying chain containing 1000 chain links. The length is 0.0533km. What is the length of a

Leya [2.2K]

Answer:

length of a single chain link = 5.33 cm

Step-by-step explanation:

Given data: chain contained 1000 chain links

total length was 0.0533km

1km = 1000m

1m = 100cm therefore 1km = 100000cm

total length in cm = 0.0533* 100000

total length in cm = 5330 cm

length of a single chain link = 5330/1000

length of a single chain link = 5.33 cm

What is the probability that a 13-card bridge hand contains all cards from the same suit?

slega [8]

The total number of 13-card hands that can be dealt is 52C13. Four of these are of the same suit. Therefore the required probability is given by:
$\frac{4}{52C13}= 6.3\times 10^{-12}$
