We can solve this by calculating the arch lengths on the track and adding them to the straight lengths on the track.
To calculate the arch lengths, we can pretend the arches are semicircles and calculate the arch length. We know that the diameter is 100 meters, and the circumference formula is diameter times pi. 100 times pi is 314, using 3.14 as pi, but we divide this by two since we are calculating the arch length of a semicircle, not a full circle. Dividing 314 by two gives us 157. However, we multiply this by two since we have to include the other arch's length and the lengths are the same, giving us 314 again. adding this to 200, the straight side lengths of the track, we get our final answer, 514 meters.

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why? (5 points)
Group of answer choices
(6, 20), because the point does not lie on any axis
(3, 11), because the point lies between the two axes
(3, 11), because one of the lines passes through this point
(6, 20), because both lines pass through this point
y=x+14 line 1
y=3x+2 line 2
These are both the equation of lines written in slope intercept form
y=mx+b where m is the slope and the point (0,b) is the y intercept.
The first line has a slope of m=1. The 2nd line has a slope of m=3
Since these lines have different slopes, they are not parallel, thus they will cross at some point. What you have to determine is where the lines cross, which will be a point (x,y) that is on both lines.
We already have y solved in terms of x from either equation so we can use substitution to solve the system.
Since y=x+14 from line 1, put x+14 in place of y in the equation of line 2.
x+14=3x+2
solve for x.
Subtract x from both sides...
14= 3x-x+2
14=2x+2
subtract 2 from both sides
14-2=2x
12=2x
divide both sides by 2
6=x
We now have the x value of the common point. Plug the value 6 in for x in one of the original equations and solve for y.
y=6+14
y=20
These two lines cross at the point (6,20) which is a point the two lines have in common.

Brenna writes a product of six negative factors. She uses the following steps to determine that the product of the six numbers will be positive. Step 3 is missing.
Group the factors into pairs.
The numbers in each pair have the same sign.
_____________________________________
The product of three positive numbers is positive.
Therefore, the product of the original six factors is positive.
What is step 3?
A. The product of two numbers with the same sign is positive.
B. The product of two numbers with different signs is negative.
C. The factors in a product can be grouped in any way without changing the value of the product.
D. The factors in a product can be written in any order without changing the value of the product.
Answer:
A
Step-by-step explanation:
The product of two numbers with the same sign is positive.
Since the numbers in each pair have the same sign, the product will be positive.

Estimate the sum: 1 3/7 + 3 5/9 + 1/2. Show your work.
Answer:
The correct answer is 5 61/126!
Step-by-step explanation:
Leave a fraction alone
1 3/7
Find the Addend
9x3=27+5=32 = 32/9
Find the sum and simplify
1 3/7 + 32/9 = 691/126 = 5 61/126
To estimate the sum of the given terms: 13/7, 35/9, and 1/2, we can convert each term to a decimal number and then add them together. First, let's convert 13/7 to a decimal.
To do this, we divide [tex]13 by 7: 13 ÷ 7 = 1.857[/tex] Next, let's convert 35/9 to a decimal. Dividing 35 by 9 gives us: [tex]35 ÷ 9 = 3.889[/tex] Finally, we convert 1/2 to a decimal by dividing 1 by 2:[tex]1 ÷ 2 = 0.5[/tex] Now that we have converted all the terms to decimals, we can add them together: [tex]1.857 + 3.889 + 0.5 = 6.246[/tex]
Therefore, the estimate of the sum of the given terms is 6.246. It's important to note that this is an estimate because we rounded the decimal values. If you need a more precise answer, you can use a calculator or longer division to get more decimal places. However, for most practical purposes, this estimate should suffice.

Answer:
Answer:
See the graph attached. The red arrow represents the shaded area.
Explanation:
The inequality and its solution are given:
The solution set is all real numbers less than or equal to -50.
In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.
To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.
Please, see the graph attached. The red arrow represents the shaded area.

Answer:
The first two is x=60
Step-by-step explanation:
1.5/90 = 1/x
1.5x = 90 x 1
1.5x/1.5 = 90/1.5
x = 60
Answer:
a. 90/ 4.5 = 20 flags per yard
b. 4.5/ 90 = 0.05 = 5 hundredths of a yard
c. 0.75 x 3 colours = 2.25 yards
4.5 = 90 flags so 4.5/2 = 2.25 = 45 flags
Justifies she is correct when saying 45 flags can be made with 3 x 0.75 material as this is equal to 2.25 yards which is half of 4.5 yards equal to 90 flags.
To find 4.5 we have 3 pieces of material to begin with for part a and part b
This shows 1.5 x 3 = 4.5 yards
To find 2.25 we have 3 pieces of material in part c.
This shows 0.75 x 3 = 2.25 yards
what is the mean absolute deviation of the data set below?
3,1,4,4,4,1,1,2,1,5
Answer:
1.4
Step-by-step explanation:
Step 1: We have to find the mean of the data set
The mean is the average or the sum of all the numbers divided by the amount of numbers there are.
3 + 1 + 4 + 4 + 4 + 1 + 1 + 2 + 1 + 5 = 26
There are 10 numbers in total so, 26/10 = 2.6
Step 2: We now know the mean so now we have to find the deviation
3 - 2.6, |1 - 2.6|, 4 - 2.6, 4 - 2.6... so on, (Note: this is just finding the distance between the numbers and the mean)
The results are, 0.4 + 1.6 + 1.4 + 1.4 + 1.4 + 1.6 + 1.6 + 0.6 + 1.6 + 2.4
This is equal to 14
Step 3: Lastly, we have to find the mean of the deviations
We know the mean is 14
We have 10 numbers
Therefore, 14/10 = 1.4 is the MAD
To make grape juice, water is added to a large cylindrical vat of grapes. If the diameter of the vat is 16 feet, what is the area of the base of the vat? Use 3.14 for π.
Answer:
200.96cm^2 base area
Step-by-step explanation:
Eq of circle area = πr^2
= 3.14 x 8^2
3.14 x 64
200.96cm^2
.
The area of the base of the Vat is 200.96 ft².
Base area of a cylinder:Area = πr²where
r = radius
π = 3.14
The grape juice is added to the large cylindrical vat. The diameter of the grape Juice is 16 feet.
Therefore,
Base area of the cylinder is a circle.
Base area = πr²
diameter = 16 feet
radius = 16 / 2 = 8 feet
Base area = 3.14 × 8²
Base area = 3.14 × 64
Base area = 200.96 ft²
