A book sold
34,900
copies in its first month of release. Suppose this represents
9.1%
of the number of copies sold to date. How many copies have been sold to date?
Round your answer to the nearest whole number.
Let X be the number of copies sold to date.
0.091 * X = 34900
X = 34900 / 0.091
X ≈ 384615.38
The number of copies sold to date is approximately 384,615.
Light travels
×310^5
kilometers in one second. How far does it travel in
47
seconds?
Write your answer in scientific notation.
To find the distance travelled in 47 seconds, we need to multiply the speed of light by the number of seconds.
×310^5 * 47 = 310^5 * 47
Since both numbers are in scientific notation, we can simply multiply the coefficients and add the exponents.
310 * 47 = 14570
The exponent remains the same.
Therefore, the distance light travels in 47 seconds is 1.4570 × 10^5 kilometers.

(a) The ratio of daisies to all flowers in the vase is (13 - 9):13 or 4:13.
(b) The ratio of daisies to roses is 4:9.
Lucy drove
13
laps on a race track. Each lap was the same length. If she drove a total of
57.2mi
what was the length of each lap? Write your answer in yards.
Use the table of conversion facts as necessary, and do not round your answer.
1760 yd = 1mi
To find the length of each lap in yards, we need to convert the total distance (57.2 miles) to yards and then divide by the number of laps (13).
1 mile = 1760 yards
57.2 miles = 57.2 * 1760 yards = 100672 yards
Length of each lap = 100672 yards / 13 laps = 7759.38 yards (rounded to two decimal places)
Therefore, the length of each lap is 7759.38 yards.
