The minute hand of a clock, while moving, creates an arc that is some part of a circle.

Since the minute hand is only moving for 45 minutes, it moves 3/4 of an entire circle.

This circle would have radius of 4.5 inches.
The circumference of a circle is πd, where d is 2r.

We can substitute 2*4.5 for d.

The circumference of a circle with radius of 4.5 is 9π.

Since only 3/4 of the entire circumference is travelled, multiply 9π by 3/4.

(3/4)*9π=27π/4, or ≈21.206

Would you please explain how you got 625 as the answer?

If on the sixth day Annie has 5/8 of the bag left, that means she ate 3/8 in 6 days. (3/8)/6=1/16, so Annie eats 1/16 of the bag per day.

By the 9th day, she will have eaten 9/16 of the bag, meaning 7/16 of the bag is left.

Let x=the number of sweets in the bag.

(7/16)x=63. To get rid of the coefficient of x, multiply both sides by (16/7), resulting in

x=63*(16/7), which also is x=144

Therefore, the number of sweets in the bag at the start is 144.

Would you please explain how you got 92 degrees as the answer?

To find the angle of the circle graph, we must first find how many total people are accounted for in this graph. 

Plugging in from the given information, 53+8+155+17+145+10+98+2=488

Since circles are made up of 360 total degrees, we divide 360/488 for the degrees per person. This also simplifies to 45/61.

Since 145 people are in the "45-54 year-old Males" sector, we multiply 145*(45/61).

145*(45-61)≈106.967
106.967 to the nearest whole number is 107, so the answer is 107.

Instead of using "snake" and "fish", we will set snake and fish equal to s and f, respectively.

The equation s=2f is true.

Since 9 fish are left in the shop after 5 are sold, the original number of fish was 14.

If you substitute this into the first equation, s=2*14, so s=28.

To find what percent of money the salesman buys the coat for, we can say that the original price is 100% of the value.

If 12.5% is discounted, 87.5% is left to pay for.

87.5% is the same as 7/8, so we multiply 64*(7/8), which equals 56.

If he sold the coat for a profit of 30%, the amount he profited is 130% of 56
130% is also equal to 1.3, so 56*1.3=72.8

We know that a 15% discount was given, so 72.8 is only 85% of the marked price. 

we can use the equation 72.8/x=85/100, which simplifies to 72.8/x=17/20

By cross multiplying, we get 17x=72.8*20, which is also 17x=1456

By dividing both sides by 17, we get x≈$85.65

As AD=EG, the diagram shown above must be a rectangle.
The area of a rectangle is defined as length*width.

AD*DC must be equal to EG*FH, since EG and FH are also perpendicular to sides AD and DC.

We know that AD=18, DC=27, and EG=18.

By setting FH=x, we get the equation

18*27=18x.

By dividing both sides by 18, we get x=27.

If the numbers are ordered from least to greatest, they would go as follows:
0.0123, 0.10203, 0.112233, 0.1223, 0.123, 0.123, 0.13.

The second and sixth numbers are then circled and added together. The second and sixth numbers are 0.10203 and 0.123.
0.10203+0.123=0.22503

Daniel,
0.75 is what is left of 60 from the original rectangle.

To find the percent decrease, you must subtract .75 from 1. The answer is then .25, or 25%.
