Answer:
He could use 104 pages in the photo books .
Step-by-step explanation:
Given :
A photographer has 591 photos of animals and 234 photos of plants.
Each page of the photo books holds 8 photos.
To Find : Fewest number of pages he could use in the photo books.
Solution :
A photographer has 591 photos of animals and 234 photos of plants.
Thus total no. of photos he have = 591+234 = 825 photos
Since he wants to put all the photos into photo book
No. of pages required for 8 photos = 1
No. of pages required for 1 photo = 1/8
No. of pages required for 825 photos:
=
⇒103.125 pages ≈ 104 pages
Hence he could use 104 pages in the photo books .
ANSWER:
STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:
The slope can be calculated as follows:
We use the points (4,7) and (1,1) to calculate the slope:
Now, we calculate the value of b, using the point (1,1) and the slope, like this:
Therefore, the equation would be:
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above and solve for P
Given:
Area of a circle, A=50.265 sq. units.
Radius of circle, r = 4 units.
To find:
The value of π to the nearest thousandth.
Solution:
Formula for area of a circle is
Now, using expression, we can find the value of π.
Approximate the value to the nearest thousandth (three digits after decimal).
Therefore, the approximated value of π is 3.142.
