Well, first you should know the formula for finding the full distance around a circle. The distance is also known as the circumference C:

C = 2<span>πr 

where r is the radius which is half of the diameter. since we know the diameter, then we have enough information to solve for this:

</span>C = 2<span>π(64/2) m

C = 2</span><span>π(32) m

C = 64</span><span>π m

C </span><span>≈ 200.96 m

Now you might choose this as the answer, but the problem asks for half of the distance around the circle which is half of the circumference:

1/2C = 200.96/2

1/2C = 100.48

Thus the answer is A. 100.48.</span>

A company has two manufacturing plants with daily production levels of 5x+17 and 3y-4,respectively.
Troyanec [42]

Complete question :

A company has two manufacturing plants with daily production levels of 5x + 11 items and 2x - 3 items, respectively, where x represents a minimum quantity. The first plant produces how many more items daily than the second plant?

Answer:

3x + 14

Step-by-step explanation:

Given that:

Production level of plant 1 = 5x + 11

Production level of plant 2 = 2x - 3

The first plant produces how many more items daily than the second plant :

Plant 1 production - plant 2 production

(5x + 11) - (2x - 3)

Open the bracket :

5x + 11 - 2x + 3

5x - 2x + 11 + 3

3x + 14

Daily production of plant 1 exceeds that of plant 2 by 3x + 14

Why is it important to know how to estimate quotients?
Zigmanuir [339]
In the real world you are not going to have a calculator on you 24/7. Nor will you have a pencil or paper to do longhand. You need to know how to accurately estimate your answers in order to be successful.

the width of a rectangle is 8 feet and the diagnal length of the rectangle is 13 feet which measurement is closest to the length
____ [38]

Answer:

Well the whole answer is 10.246950 smth smth but I don’t have the multiple choices so your gonna have to round yourself

Step-by-step explanation:

Okay so you have a weigh of 8 and a diagonal of 13.

If you look, theres a triangle there. One side has 8 and the diagonal that was cut forms a 13. So we have a leg and a hypotnuse. To find the other leg (length) just follow the Pythagorean theroum and solve for b or a.

Pythagorean theroum: a^2+b^2=c^2

Now subsitute c for 13 since its the hypotnuse and a or b as 8 but only one.

In this case I’m substituting a for 8.

8^2+b^2=13^2

Solve the squares

64+b^2= 169

Isolate the b

b^2=105

Now square root 105

√105 will give the answer above on a normal calculator but if you have to round, I don’t know what place but you can round.
