The 'seconds' hand on the watch goes all the way around in 1 minute. <span>15 seconds is 1/4 of a complete 1-minute revolution. </span>So, the 2 cm is 1/4 of the way around the circle that the tip makes. This makes the full circumference of the circle 8cm.
<span>The length of the second hand will be the radius of the circle. Use the following equation: </span>
2 pi radius = circumference
Since we know the circumference, plug that in, and solve for the radius:
2 pi radius = 8 cm
radius = 8cm / 2 pi =<span> 1.27 cm</span>
Answer:
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Step-by-step explanation:
we have
Divide the compound inequality into two inequalities
-----> inequality A
-----> inequality B
<em>Solve inequality A</em>
Subtract 28 both sides
Divide by 4 both sides
Rewrite
<em>Solve the inequality B</em>
Subtract 28 both sides
Divide by 4 both sides
therefore
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Step-by-step explanation:
I added together his estimations and then subtracted the total from how much money was in his bank.
2,477+2,263+3,218=7,958
10,236-7,958=2,278
I really hope this helps
Hello!
We have to use a certain formula to find the area of a parallelogram. The formula is:
A = bh
Since we already have the area and the base of the parallelogram, we will be able to find the height!
Notice how we multiply the base by the height to find the area? Well, we'll have to do the opposite to find one of its dimensions.
What's the opposite of multiplication? Division!
Formula for base:
B = A ÷ h
Substitute:
B = 60 ÷ 5
B = 12
ANSWER:
The base is 12 feet long.
Good Day!
Answer:
3.
Step-by-step explanation:
Rearrange to make it easier: 6*x+3*y-(12)=0
Find like factors and eliminate them: 6x + 3y - 12 = 3 x (2x + y - 4)
So then you get 3 = 0. So y would be 3.
