Answer: The correct option is (B) 27 units.

Step-by-step explanation: Given that a circle has a circumference of 85 units.

We are to find the approximate length of diameter of the circle.

The circumference of a circle with diameter d units is given by

$C=\pi d.$

In the given circle, we have

C = 85 units, diameter, d = ?

So,

$C=\pi d\\\\\Rightarrow 85=\dfrac{22}{7}\times d\\\\\Rightarrow d=\dfrac{85\times 7}{22}\\\\\Rightarrow d=27.04545...$

Thus, the approximate length of the diameter is 27 units.

Option (B) is CORRECT.

Ipatiy [6.2K]

<span>If Dingane has $8.00, and thirty percent of that money is from five cent coins, then 8 x 0.3 = $2.40 of Dingane's money is made of five cent coins. In this case the number of five cent coins is the number of cents divided by five: 240/5 = 48. Therefore, Dingane has forty-eight five-cent coins.</span>

If a concrete column is 6 inches by 6 inches square and 8 ft. long, calculate its weight in Newtons, given a specific weight of

tangare [24]

<h2>Weight of column is 555.83 N</h2>

Step-by-step explanation:

Size of column = 6 inch x 6 inch x 8 ft

Size of column = 0.5 ft x 0.5 ft x 8 ft

Volume of column = 0.5 x 0.5 x 8 = 2 ft³

Specific weight of concrete = 62.4 lb/ft³

Mass = Volume x Specific weight

Mass = 2 x 62.4

Mass = 124.8 lb = 124.8 x 0.454 = 56.66 kg

Weight = 56.66 x 9.81 = 555.83 N

Weight of column is 555.83 N

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has. If each loaf

Ganezh [65]

Answer:

Approximately 4 loaves of bread.

Step-by-step explanation:

Let us get out the total amount of flour that Josh has first of all. This is $13\frac{1}{3}$ cups of flour.

Each lof requires $3\frac{4}{5}$ cups of flour. This means that to make a loaf, he will be taking out this quantity of flour from the whole lot.

To get the total number of loaves he can make with this quantity of flour, we will have to divide the total quantity of flour available by the quantity required to make a single loaf.

This will be $13\frac{1}{3}$ ÷ $3\frac{4}{5}$ = $3\frac{29}{57}$ . This is approximately 4 loaves of bread
