It would be 32 1/4 - 30 5/6
129/4 - 185/6
387-370 / 12 = 17/12 = 1 5/12
So, he dived for 1 5/12 inches
1. 24, 60
24 = {1, 2, 3, 4, 6, 8, 12, 24}
60 = {1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60}
The GCF is 12.
2. 7, 9
7 = {1, 7}
9 = {1, 3, 9}
The GCF is 1.
3. 9, 12, 15
9 = {1, 3, 9}
12 = {1, 2, 3, 4, 6, 12}
15 = {1, 3, 5, 15}
The GCF is 3.
4. An example of this is #5. It can help you figure out what the greatest amount you can have is.
5. 14 boys and 21 girls.
14 + 21 = 35
Find the multiples of 35.
{ 1, 5, 7, 35 }
Obviously 35 can't be used, because there will be only 1 group. So the greatest number of groups would be 7, each containing 5 students.
JCL because
JCL + LCT = 90
If you notice there is a right angle symbol
First, we must determine the circumference of the paddle wheel.
The formula for the circumference of a circle is:
c = 2πr
Where r is the radius of the circle. However, we know d = 2r where d is the diameter of the circle.
Therefore:
c = 2rπ = dπ
Substituting 8ft for d gives a circumference of:
c = 8πft
The time it takes to complete 1 revolution can be found using the formula:
t = d/s
Where:
t is the time it takes: what we are solving for in this problem.
d is the distance traveled: we calculated this as 8πft
s is the speed traveled: from the problem we know this is
6.7ft/sec
Substituting and calculating t gives:
t = 8πft / (6.7ft/sec)
t = 1.2πsec
Two find how long it would take for 100 revolutions we can multiply this time by 100
100 × 1.6πsec ⇒ 122.2πsec
If a number is required for the answer we can use 3.14 as an estimate for π giving:
122.2πsec ⇒ 122.2 × 3.14sec ⇒ 383sec
Answer:
Step-by-step explanation:
<u>Dimensions of the picture:</u>
<u>Area of the picture:</u>
Scale factor = 2.5
<u>Enlarged picture's area:</u>
- 40*2.5*2.5 = 250 in² (scale factor affects both dimensions)
Option B is correct
