Answer:
The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm.
Step-by-step explanation:
first we would use A=length x width
so a = 614 cm x 212 cm = 130,168 cm
now we find the area of the pond using a= pi x r^2
the diameter is 114 cm so we cut that in half to find the radius which is 57 cm
a = pi x 57^2
a= 3.14 x 3249
a= 10201.86 cm
now we subtract the area of the pond from the whole area
130,168 - 10201.86 = 119,966.14 cm
The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm
The area of the park on the map is 641.37 square yards.
To find the area of the park on the map, we need to first find the actual dimensions of the park in yards, and then calculate the area.
It is given that :
Scale on the map: 114 cm : 8 yards
Width of the park on the map: 212 cm
Length of the park on map: 614 cm
Diameter of the circular pond on the map: 114 cm
We know that, 1 yard = 114cm/8 = 14.25 cm
Therefore, the width of the park in yards = 14.91 yards.
Area of rectangle: Width x Length
Thus, Area of park = 14.91 yards x 43.09 yards
= 641.37 yards
Therefore the area of the park on the map is approximately 641.37 square yards.

Step-by-step explanation: try 14
Which points have a distance of 6 units between them?
Select all that apply.
Answer: The answers are A, B, C.
Step-by-step explanation:
A bus travels at a constant speed from point A to point B, which are 600 km apart. Some time later, a motorcyclist begins the trip from A to B, traveling at 100 km/h. The motorcyclist overtakes the bus at 150 km from A, and continues on to point B. The motorcyclist arrives at B, rests for 1 hour, and begins the return trip to A, crossing paths with the bus. When the bus arrives at B, the motorcyclist is 200 km from B. How far from B did the motorcycle and bus meet the second time?
Step-by-step explanation:
the motorcyclist starts x hours after the bus.
it takes the motorcyclist 1.5 hours to meet the bus the first time, 6 hours to reach B, rest 1 hour and go another 2 hours before the bus arrives at B.
so, the bus needs
x + 9 hours to reach B.
x + 1.5 hours for 150 km (for the first meeting with the motorcyclist).
the speed of the bus is 600/(x + 9) km/h or 150/(x + 1.5) km/h.
so,
600/(x + 9) = 150/(x + 1.5)
4/(x + 9) = 1/(x + 1.5)
4(x + 1.5)/(x + 9) = 1
4(x + 1.5) = x + 9
4x + 6 = x + 9
3x + 6 = 9
3x = 3
x = 1
the motorcyclist starts 1 hour after the bus.
the speed of the bus is
600/(x + 9) = 600/(1 + 9) = 600/10 = 60 km/h
when the motorcyclist is starting its return trip, he is 7 hours after his start, and the bus is 7+x = 7+1 = 8 hours after its start, that means at
8×60 = 480 km of its total trip of 600 km.
120 km are still left for the bus to go.
from that point on both travel the same time y going with their speeds until they meet the second time.
the motorcyclist travels 100y km building up distance from B, while the bus travels 60y km reducing the 120 km distance from B.
when they meet the second time, the distance from B for the motorcyclist is the same as the remaining distance for the bus.
so,
100y = 120 - 60y
160y = 120
y = 120/160 = 3/4 = 0.75 hours
so, they meet at
100 × 0.75 = 75 km from B.

Julia loves collecting baskets. Every month she adds two new baskets to her collection. In the month of March she has 60 baskets. She’s worried she will soon run out of room in her apartment to keep her baskets. Write an equation that represents the percent of change of her basket collection from the beginning of the year to the end of the year, then solve.
The linear function that represents the amount of baskets in the xth month of the year is given as follows:
The percentage of her collection that she needs to get rid of is of 3.85%.
Linear Function:-
The definition of a linear function is:
y = b + mx
In which the parameters of the equation are given as follows:
•b is the value of y when x=0
•m is the rate of change for each unit of x
Every month she adds 2 new baskets to her collection, hence the slope is of : m = 2
Then: y = b + 2x
From the March amount, when x = 3, y = 60, hence the intercept b is given as follows:
60 = b + 6
b = 54
Hence the equation is: y = 54 + 2x
At the end of the year (12 months) the amount of baskets that she will have is of:
y = 54 + 2 × 12 = 78
Hence, she has to get rid of 3 baskets, as 78 - 75 = 3, and the percentage is of:
p = 3/78 × 100% = 3.85%.

1. A straight fence is constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. A certain fence begins and ends with a post. If there are 7 posts, what is the total length of the fence?
Answer:
72
Step-by-step explanation:
First, we will multiply the number of posts (7) by the posts' width (6) to get 42.
Since there is a chain between each post, there are 6 chains.
Multiplying the number of chains (6) by the chains' length (5), we get 30.
The question asks us to find the total length of the fence, so we add 42 and 30 and get 72.

Consider the numbers 13, 16, 27, and 41. a. Which of these numbers are a prime? How do you know? b. Which of these numbers are composite. How do you know? (NEED AN ANSWER ASAP!)
Consider the 3-digit number which are written by using only the digits 1,2,3,4,5. How many of these have two equal digits and one different digit?
5 3-digit numbers that have three equal digits.
we need to apply the principle of inclusion-exclusion to account for the fact that some 3-digit numbers may be counted multiple times.
any 3-digit number that has three equal digits will be counted twice once as a 3-digit number with two equal digits and one different digit, and once as a 3-digit number with three equal digits.
There are 5 choices for the digit that is repeated, and 1 way to arrange the digits, so there are 5 3-digit numbers that have three equal digits.
Therefore, we need to subtract 5 from the total number of 3-digit numbers that have two equal digits and one different digit.
60 number are 3-digit numbers that have two equal digits and one different digit.
What is permutation and combination?Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter.
The given digits are,
1, 2, 3, 4, 5.
Since, to find the 3 digits numbers which are written by using given digits, and have two equal digits and one different digit,
Here order of arrangement matters.
Use permutation formula,
From 5 digits, 3 are chosen,
Ways of arrangement = ⁵P₃
= 5! / (5-3)!
= 5! / 2!
= 5 x 4 x 3 x 2! / 2!
= 60
There are total 60 different ways, in which numbers can be arranged.

identify the slope and y-intercept of the function y = -2x+4
Answer:
Slope = -2
y-intercept = (0, 4)
Step-by-step explanation:
The equation is written in slope-intercept form, y = mx + b, where "m = slope" and "b = y-intercept". Thus, we have to identify what part of the equation is part of each element in slope-intercept form:
Slope-intercept form
y = mx + b
Equation:
y = -2x + 4
m = -2
b = 4
Thus, the slope is -2 and the y-intercept is (0, 4)

Answer:
D (Alicia did 5 more jumping jacks per minute than Melissa.)
Step-by-step explanation:
Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute. To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

Step-by-step explanation:
You want the number of teeth that have touched when a 12-tooth gear and an 8-tooth gear turn until they have the same relative position as when they started.
Least common multipleThe least common multiple (LCM) of 8 and 12 is the smallest integer that is a positive integer multiple of both these numbers. That value is ...
24 = 8·3 = 12·2
It is often found quickly by making use of your knowledge of multiplication tables.
How to find itThe LCM can be found by looking at the unique factors of the numbers, taking each to the highest of the powers:
8 = 2³
12 = 2² × 3
Among the factors 2 and 3, the highest powers are 2³ and 3¹, so ...
2³ × 3¹ = 24
is the LCM.
The LCM is also the product of the numbers, divided by their greatest common factor (GCF):
LCM(8, 12) = 8·12/4 = 24

The problem statement is telling you to look for the same number in the two right columns of the table. That number is 24. It goes in the blanks at the bottom.
