Answer:
Part 1
If the actual park is 250 yards LONG, I think it means that its LENGTH is also 250 yards
Part 2
It's a proportion:
5=x
7=250
5*250:7=178.6 yards
The area is 178.6 yards wide and 250 yards long

the ratio of large triangles to small triangles is 2-6 .If there are 100 triangles in the design ,how many small triangles are there.
Answer:
75 small triangles
Step-by-step explanation:
1. Reduce the ratio: 2-6 = 1-3
2. Write each of them as a fraction of a whole:
Small total = 3/(1+3) = 3/4 of the total amount
3. Multiply the ratio to get the answer: 3/4 * 100 = 75
Find the slope of the line passing through the given points (5, 14) and (1, -2).
A) -3
B 3
D -4
E -9
Answer:
Answer:3
Explanation:Answer:
slope = 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 14) and (x₂, y₂ ) = (1, - 2)
m = [tex]\frac{-2-14}{1-5}[/tex] = [tex]\frac{-16}{-4}[/tex] = 4
a force acts in a direction (4,2) moving an object along a straight path from (2,-4) to (10,1). How much work is done by the force?
A. 12 joules
B. 42 joules
C. 48 joules
D. 78 joules
Answer:
42 Joules
Step-by-step explanation:
Edge 2020
Work done by the force is 42 units which is correct option(C)
What is Work done?The work done by a force in moving along a vector that is the product of their.
Let the the object move from P(2,-4) to Q(10,1)
Here, the position vectors
[tex]\vec{p}[/tex] = [tex]2\vec {i}+(-4)\vec {j}[/tex], [tex]\vec{q}[/tex] = [tex]10\vec i+\vec{j}[/tex]
Hence [tex]\vec{PQ}[/tex] = [tex]\vec{q}[/tex] -[tex]\vec{p}[/tex] = [tex]10\vec i+\vec{j}[/tex] - [tex]2\vec {i}+(-4)\vec {j}[/tex],
[tex]\vec{PQ}[/tex] = [tex]8\vec i+5\vec{j}[/tex]
Force acts in a direction (4,2)
So [tex]\vec{F}[/tex] = [tex]4\vec i+2\vec{j}[/tex]
∴ Work done = [tex]\vec{F}.\vec{PQ}[/tex] = [tex](4\vec i+2\vec{j})[/tex] [tex].(8\vec i+5\vec{j})[/tex]
Work done = 32+10 =42 units
Hence work done by the force is 42 units

Find the value of r so the line that passes through (-3,2) and (3,r) has a slope of -1/2
Please Help!!
Step-by-step explanation:
gradient = (y2 - y1)/(x2 - x1)
-1/2 = (r - 2)/(3 - (-3))
-1/2 = (r - 2)/6
-1/2(6) = r - 2
-3 = r - 2
-3 + 2 = r

A triangle with a vertex at point Y(-3, 7) is dilated by a scale factor represented by the coordinate pair (2/3x, 2/3y ). What is the location of Y'?
Please look at the picture below for the answer choices.
Answer:
[tex]Y' = (-2, 4\frac{2}{3})[/tex]
Step-by-step explanation:
Given
[tex]Y = (-3,7)[/tex]
[tex]Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)[/tex]
Required
Determine Y'
Y' can be solved by multiplying the scale factor by Y
i.e.
[tex]Y' = Scale\ Factor * Y[/tex]
For, the x coordinates.
[tex]Y' = \frac{2}{3}x[/tex]
Where
[tex]x = -3[/tex]
[tex]Y' = \frac{2}{3} * -3[/tex]
[tex]Y' = \frac{-6}{3}[/tex]
[tex]Y = -2[/tex]
For the y coordinates:
[tex]Y' = \frac{2}{3}y[/tex]
Where
[tex]y = 7[/tex]
[tex]Y' = \frac{2}{3} * 7[/tex]
[tex]Y' = \frac{14}{3}[/tex]
[tex]Y' = 4\frac{2}{3}[/tex]
Hence:
[tex]Y' = (-2, 4\frac{2}{3})[/tex]

This will seem weird but all you are is doing distrubitive property.
Replace w with nine and you have this.
Step 1 (Replace/Substitute)

Directions: Write your own recipe for trail mix with a catchy name that will make people want to eat it. You can also create a slogan, logo, or package design for the mix. Your recipe must meet the following contest guidelines:
1. It must have at least five different ingredients.
2. The amount of each ingredient should be represented by a different mixed number.
3. The recipe must make exactly 10 cups of trail mix.
After you write your recipe, complete the following for your contest entry:
• Prove that your recipe makes exactly 10 cups.
• Explain the most efficient method for measuring each ingredient using only
the following two measuring cups: 31 cup and 41 cup. You can use one or both of the measuring cups. Note: Depending on the fractions that you chose
for your ingredient amounts, it may not be possible to create each exact amount using only 13 and 14 measuring cups. If you need to, you can round your ingredient amounts using benchmarks and then explain how you would estimate that amount. For example, if you need 74 cup of an ingredient, 74
cup is slightly more than 12 cup. You could fill up your 14 measuring cup twice to make 12 cup of that ingredient, and then add just a tiny bit more to estimate 74 cup.
• Use equations or other models to show how you would measure each ingredient amount with only the two measuring cup sizes.

Pamela received some gift cards for music and movie downloads for her birthday. Using one of them, she downloaded 4 songs and 1 movie, which cost a total of $16. Using another, she purchased 6 songs and 1 movie, which cost a total of $18. How much does each download cost?
Downloads cost $______for a song and $________for a movie.
Answer:
Downloaded music 1 EACH: $1
Movie 1 EACH: $12
Step-by-step explanation:
4 songs and 1 movie = $16
6 songs and 1 movie = $18
if we minus the two formulas we get:
2 songs = $2
Try it out on the formula, it will work.
$4 + x = $16
x = $12
$6 + $12 = $18

At a factory the basic week is 40 hours. During a particular week Mr. Ali earned a gross wage of $491.15, but $156.75 was overtime.Calculate Mr. Ali's basic rate of payment If overtime was paid for at time-and-a-quarter, find how many hours
Answer:
Mr. Ali worked for 55 hours.
Step-by-step explanation:
Basic working hours = 40 hours
Total gross wages = $490.15
Overtime wages = $156.75
Total wages as per basic week = Total Gross wages - Overtime wages
Total wages as per basic week = $490.15 - $156.75 = $334.4
Let wages for basic hours = [tex]\$x[/tex]
[tex]40\times x = \$334.4\\\Rightarrow x = \bold{\$8.36}[/tex]
Let the number of overtime hours = [tex]y[/tex] hours.
Given that the wages for overtime are paid for at time-and-a-quarter.
As per question statement:
[tex]y\times 8.36\times \dfrac{5}{4} = $156.75\\\Rightarrow y = \bold{15\ hours}[/tex]
Total number of hours worked by Mr. Ali = 40 + 15 = 55 hours

Lost-time accidents occur in a company at a mean rate of 0.3 per day. What is the probability that the number of lost-time accidents occurring over a period of 9 days will be no more than 3? Round your answer to four decimal places.
Answer:
0.7295
Step-by-step explanation:
Given that :
Mean rate of lost time accident = 0.3 per day
probability that the number of lost-time accidents occurring over a period of 9 days will be no more than 3?
n = 9
Using binomial distribution formula :
P(x ≤3)
Probability of success (p) = 0.3
1 - p = 1- 0.3 = 0.7
nCx * p^x * (1 - p)^(n-x)
Using the binomial probability distribution calculator to save computation time :
P(x ≤3) = P(x = 0) + p(x = 1) + p(x = 2) + p(x = 3)
P(x ≤3) = 0.0403 + 0.1556 + 0.2668 + 0.2668
P(x ≤3) = 0.7295
Probabilities are used to determine the chances of events.
The probability that accidents occur no more than 3 days in 9 days is 0.7296
The given parameters are:
[tex]p = 0.3[/tex] --- the probability that an accident occurs
The probability that an accident does not occur (q) is then calculated using the following complement rule
[tex]q= 1 - p[/tex]
[tex]q= 1 - 0.3[/tex]
[tex]q= 0.7[/tex]
The probability that accidents occur no more than 3 days in 9 days is
[tex]P(x \le 3) = P(0) + P(1) + P(2) + P(3)[/tex]
Each probability is calculated using:
[tex]P = ^nC_rp^rq^{n-r}[/tex]
So, we have:
[tex]P(x \le 3) = ^9C_0(0.3)^0(0.7)^9 +^9C_1(0.3)^1(0.7)^8 + ^9C_2(0.3)^2(0.7)^7 + ^9C_3(0.3)^3(0.7)^6[/tex]
This gives
[tex]P(x \le 3) = 0.0403 + 0.1556 + 0.2668 + 0.2669[/tex]
[tex]P(x \le 3) = 0.7296[/tex]
Hence, the probability that accidents occur no more than 3 days in 9 days is 0.7296

A number of squares are connected in a row to form a rectangle. The
table shows the relationship between the number of squares, x, and the
perimeter, y, of the rectangles they form. Select all the true statements
about this relation.
Answer:
✅The relation is a function
✅The graph of the function is linear
✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex]
Step-by-step explanation:
✅The relation is a function because each domain (number of squares) has exactly one range (perimeter).
✅The graph of the function is linear because the difference between any two successive y-values gives us the same value of 4.
That is: 12 - 8 = 16 - 12 = 20 - 16 = 4.
✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex], because if we substitute any pair of values (x, y) into the equation, the equation would be true.
For example, using the pair (1, 8), substitute x = 1, and y = 8 in [tex] y = 4x + 4 [/tex].
Thus:
[tex] 8 = 4(1) + 4 [/tex]
[tex] 8 = 8 [/tex] (True).
