The diagram shows the dimensions of a school playground. What is the area of the playground?
Answers
Answer:
1574yd^2
Step-by-step explanation:
i split into 3, 2 rectangles and a triangle
40 x 30 = 1200
30 - 8 = 22 (height)
60 - 40 = 20 (width)
14 x 22 = 308
20 - 14 = 6 (base of triangle)
formula of triangle = (b x h) / 2
6 x 22 = 132 / 2 = 66
1200 + 66 + 308 = 1574

Answers:
The forces have opposite directions
The forces have equal magnitudes
=====================================================
Explanation:
Imagine a bucket of water being held up by a rope.
Gravity pulls down on the bucket with a constant force. The reason why the bucket doesn't fall to the ground is because the tension in the rope is holding it up.
More specifically, the force of the rope's tension is exactly matching the force of gravity. So we have equal magnitudes here. However, the force vectors point in complete opposite directions. Gravity points down and the tension of the rope points up. The two opposite directions cancel out to create balance and that's why the object doesn't move. It has velocity = 0 which is considered a constant velocity even though it's not something like 3 m/s.
If the forces acted in the same direction, then the magnitudes would add up to accelerate the object (either downward or upward). However, the bucket stays fixed in place, so it's clear that the vectors must be opposite in nature.
---------------
Now consider a skydiver. At some point of the descent, the skydiver will hit terminal velocity. This is the fastest s/he can fall because the force of gravity pulling down counterbalances perfectly with the upward force of wind/air resistance pushing upward. The air is resisting the downward motion being a form of friction. In this case, the magnitude of the gravitational force is the same as the magnitude of the upward air resistance.
Unlike the bucket of water, the skydiver is of course moving. They are moving at a constant velocity since they cannot accelerate any faster. Hence the name "terminal" meaning "the final or ending velocity". It is when the parachute is deployed that will apply a much greater upward force, which then slows down the downward velocity to allow the skydiver to safely land.
---------------
In both examples, we have a constant velocity happening when the vectors pull in equal amounts but in opposite directions. Think of it like a tug-of-war to keep everything balance. If there is an imbalance of any kind, then acceleration will happen.

Answers
Given :
Brianna is a waitress in an upscale restaurant. On Friday she waited on 12 groups of customers who spent an average of $186 per group.
Her tips averaged 18% of the total amount spent by all the groups of customers that day.
To Find :
Brianna's tip income earnings on Friday.
Solution :
Total amount of money spent by 12 groups :
P = $ 12×186 = $2232 .
She got tip of 18% of the total amount spent by all the groups of customers.
[tex]T = P\times \dfrac{20}{100}\\\\T= 2232\times \dfrac{20}{100}\\\\T=\$446.4[/tex]
Brianna's tip income earnings on Friday is $446.4 .
Hence, this is the required solution.

Answers
Answer:
b) |y-11|=6
c) |z-1|=5
d) |a-0|=1/2
Step-by-step explanation:
This definetly works!
The absolute value equations are =
1) |x - 11| = 6
2) |x + 1| = 5
3) |x| = 0.5
1) To satisfy the solution set of 5 and 17 on a number line, we can write an absolute value equation as follows:
|x - 11| = 6
Explanation: The midpoint between 5 and 17 is 11, which serves as the value c in the equation.
The absolute value of x minus 11 should be equal to the distance between the midpoint and either endpoint, which is 6.
2) To satisfy the solution set of -4 and 6 on a number line, we can write an absolute value equation as follows:
|x + 1| = 5
Explanation: The midpoint between -4 and 6 is -1, which is the value c in the equation.
The absolute value of x plus 1 should be equal to the distance between the midpoint and either endpoint, which is 5.
3) To satisfy the solution set of -0.5 and 0.5 on a number line, we can write an absolute value equation as follows:
|x| = 0.5
Explanation: In this case, the midpoint between -0.5 and 0.5 is 0, which is the value c in the equation.
The absolute value of x should be equal to the distance between the midpoint and either endpoint, which is 0.5.

There were 8 judges at a gymnastics competition. Kathleen received these scores for her performance on the uneven parallel bars.
8.9, 8.7, 8.9, 9.2, 8.8, 8.2, 8.9, 8.8
a. Find the mean, median, and mode.
b. Which statistic reflects a typical score? Explain.
Answers
Answer:
below
Step-by-step explanation:
mean : 8.8
The mean is the average, so you find it by adding all the numbers together and dividing by n, or how many numbers there are. For this, I added to get 70.4 and divided that by 8 (8 total scores).
70.4/8 = 8.8.
median : 8.85
The median is the middle of the data set, so you put the numbers in increasing order (lowest number to highest number) and then finding the middle of that set. For this set, since there is an even number of numbers (8), you have to find the middle by adding the two middle numbers and dividing by 2.
8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2
The middle numbers are 8.8 and 8.9, so you add those together and divide by 2 to get 8.85.
mode : 8.9
The mode is just what number appears most often. Because 8.9 appears three times in this data set, more than any other number, the mode is 8.9.
b. The mean reflects a typical score because it is the average, and is used most often when someone is expressing a typical or "average" score. It is the score most people are likely to get, and as there are no outliers in this data set, it reflects a typical score for this data set. It is also the same as the mode, or most often score, in this data set.
1) Put the numbers in order
8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2
2) mean is average
70.4/8 = 8.8
3) Median is the middle number; if m = 2, then divide them by 2
17.7/2 = 8.85
4) Mode is most often
8.9 (3 times)

1. a number is as much greater than 21 as it is less than 71. find the number
.
2. find 2 consecutive natural number whose sum is 63.
Answers
1. A number is as much greater than 21 as it is less than 71. Find the number
Solution -
Let the number be x.
x - 21 (number is as much greater than 21)71 - x (it is less than 71)As both the value of x - 21 and 71 - x is same hence,
=> x - 21 = 71 - x
=> x + x = 71 + 21
=> 2x = 92
=> x = 92/2
=> x = 46
Hence, the number is 46.
2. Find 2 consecutive natural number whose sum is 63.
Let the two consecutive numbers be x and x + 1.
=> x + (x + 1) = 63 (A.T.Q)
=> x + x + 1 = 63
=> 2x = 63 - 1
=> 2x = 62
=> x =62/2
=> x = 31
Hence, the consecutive natural numbers whose sum is 63 are 31 and 32.

Step-by-step explanation:
Here is the formula.
[tex]A=P(1+r)^{n}[/tex]
A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
