Answer:

a) 2.5π, b) ≈673 times

Step-by-step explanation:

diameter = 2.5

circumference = diameter*π

circumference = 2.5π

5280/2.5π

≈5280/2.5*3.14

≈5280/7.85

≈672.6, ≈673

Answer:

I think its 345.6m^3

Answer:A fraction represents a part of a whole

Step-by-step explanation:

eg: 3/5 by 5/5

please view explanation

The definition of a fraction is a part of a whole .

If a whole is  divided into equal parts, these equal parts are called fractions.

Fractions are written like this :

[tex]\boxed{\\\begin{minipage}{4cm}fractions\\$\displaystyle\frac{x\xrightarrow{numerator}}{y\xrightarrow{denominator}} \\ \end{minipage}}[/tex]

 Where

y = the number of total parts

x = the number of parts taken

Now, it doesn't necessarily have to be a pizza or a cake.

Suppose your companion Danette has 32 pencils. Out of them, 8 pencils are red.

What fraction of the pencils is red?

Total number of pencils = 32 (denominator)

Number of red pencils = 8 (numerator)

So the fraction of red pencils is :

[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{8}{32} \\ \end{minipage}}[/tex]

If the numerator and denominator are divisible by the same number, then we can reduce the fraction :

[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{1}{4} $\\ \end{minipage}}[/tex]

Step-by-step explanation:

Answer:The number of all possible codes = 26 * 26 * 10 * 10 * 10 = 676000

Step-by-step explanation:

five digit code; each code is 3 digits (0-9) followed by two letters. That's ten numbers to choose from and 26 letters in the alphabet.

The problem suggests numbers and letters can be used more than once, like having a code: 555AA

To find the number of possible codes, you multiply by the choices for each digit.

10*10*10*26*26 = 676,000

Answer:

26 * 26 * 10 * 10 * 10 = 676000

Step-by-step explanation:

The area of the circle is the amount of space on the circle

The area of the circle is about 14 cm²

From the question, we understand that the circle fits perfectly into the grid.

This means that the area of the circle is about the same with the area of the square grid.

The area  of the square grid is:

Area = 4 * 4

Evaluate

Area = 16

The surrounding areas are triangles with the following estimated dimensions:

Base = 1.5, Height = 1.5

The area of the four triangles is:

Area = 4 * 0.5 * 1.5 * 1.5

This gives

Area = 4.5

Subtract the area of the triangle from the square

Remaining area = 16 - 4.5

Remaining area = 11.5

Approximate

Remaining area = 12

Hence, the area of the circle is about 12 cm²

To improve the grid, we simply get the actual dimension of the black region

Answer:

B

Step-by-step explanation:

Add the number of the remaining cards

8 cards of tomatoes + 3 remaining cards of carrots

since Lidia turned the cards and put away 1 carrot card.

At first she had 4 on the table but now she has 3

So, add 8+3= 11

The question is asking... what is the probability that the card Lydia turns over has a carrot on it.

so we put the number of remaining carrot cards over the total number of cards.

r=4in  4^2 is 16 then multiply it by 3.14 to get 50.24

r=2in  2^2 is 4 then multiply it by 3.14 to get 12.56

d=2in Since you have the diameter first, you just divide it by 2 and your radius is 1. 1^2 is 1     1*3.14=3.14

r=8in 8^2 is 64 then multiply it by 3.14 to get 200.96

d=12in divided 12 by 2 and you get 6. 6^2 is 36, multiply that by 3.14 to get 113.04

Step-by-step explanation:

∠CDJ = 34°.

Step-by-step explanation:

In this question AK and MJ intersect at 90°.

∠ADC = 4x° and ∠JDC = (3x - 8)°

We have to find the measurement of ∠CDJ.

Since ∠MDA = ∠KDJ = ∠ADJ = ∠MDK = 90°

Therefore ∠ADJ = ∠ADC + ∠JDC = 90°

4x + 3x - 8 = 90

7x - 8 = 90

7x = 98

x = 98/7 = 14

Therefore m∠CDJ = 3x - 8 = 3×14 - 8 = 42 - 8 = 34°

Answer is m∠CDJ = 34°

2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.

=====================================================

Explanation:

Consider the problem of 0.68 of 1, in other words 0.68*1 or simply 0.68

The number 0.68 is 68/100 or 68 over 100. We can have a 10 by 10 grid of tiny squares. Shade in 68 of them to represent 0.68 aka 68 hundredths.

So you'd have 6 full rows shaded  (to account for 0.60 so far) and then an additional 8 squares in the seventh row (adding on 0.08 to get 0.60+0.08 = 0.68)

All of this is for one square. Double this process and you'd get 0.68*2 to represent the value 1.36

In total, 2*68 = 136 squares are shaded out of 2*100 = 200 squares total.
