To show that Dan's statement is reasonable, we can set up an equation to represent the situation. Let's let x represent the number of feet of twine that Dan has cut.
We can then set up the following equation: [tex]4.75x = 249 - 40.5[/tex]
Solving for x, we find that x = 42. This means that Dan has cut 42 lengths of twine, which is what he said he would do.
Since the number of lengths of twine that Dan has cut and the amount of twine that will remain match what Dan said, his statement is reasonable.

Answer: 151/500
Step-by-step explanation:
Two square-shaped fields are next to each other. The perimeter of each field is 28 feet. The two fields are joined together to form a single rectangular field. What is the perimeter of the rectangular field?
A. 42 feet
B. 49 feet
C. 56 feet
D. 63 feet
Answer: A. 42 feet
Step-by-step explanation:
If a square has a perimeter of 28 feet, then each side would be 7 feet long because a square has 4 equal sides.
So if they are joined together to make a rectangle, the short side would be 7 feet long and the longer side would be 14 feet long.
You then add all the sides together so:
7 + 7 + 14 + 14 = 42 feet
ABC is a right triangle with vertices B (9, 4) and C (3, 9).
What are the coordinates of vertex A?
Enter your answers in the boxes.
Answer:
A (3, 4)
Step-by-step explanation:
A has to be positioned horizontally along B. This means its x coordinate is the same as x-coordinate of B which is 4
A also has to be positioned vertically below C. This means its y coordinate is the same as the y-coordinate of C. So y-coordinate of A is 3
So coordinates of A are (3, 4)

Madison and Mackenzie made $87 selling girl scout cookies. Madison made $15 more than 2 times as much as Mackenzie made. How much money did Mackenzie make?
Answer:
2 equations were used : x + y = 87 and x = 2y + 15
Step-by-step explanation:
Defining variables:
Madison = x
Mackenzie = y
-----------------------------------
Here's what we know:
Madison and Mackenzie made $87 selling girl scout cookies (TOGETHER). Therefore: x + y = 87
We also know that Madison made $15 more than 2 times as much as Mackenzie made.
Therefore: x = 2y + 15
Now we can substitute the 2nd equation (x = 2y + 15).
This gives us (2y + 15) + y = 87
After solving (2y + 15) + y = 87, we get y = 24
Okay, so now we know Mackenzie sold $24 worth of girlscout cookies...
this is also known as y = 24
---------------------------------------------------------------------------------------------------------
If we were to find out how much madison made aswell, here's what we would do.
We will put y = 24 back into the original equation (x + y = 87).
x + 24 = 87
x = 63
Madison sold $63 worth of girlscout cookies.

Find the percent equivalent 6 over 15.
Answer:
40%
Step-by-step explanation:
Because 15 is the denominator in 6/15, we might change the fraction to make 100 the denominator. In order to do it, 100 is divided by the numerator:
=40/100
Now that we know our fraction is 40/100, we can see that 40% of 6/15 is represented as a percentage.
therefore youre answer would be 40%
Answer:
40%
Step-by-step explanation:
6/15 = 40/100
Compare each investment to an investment of the same principal at the same rate compounded annually.
17. Principal: $8,000
Annual interest: 6%
Interest periods: 4
Number of years: 20
Step-by-step explanation:
income is based on a formula (rt)
r is a % of p (% being Annual Interest)
t is time (number of years)
p is principal.
17. 9,600$ in interest (lost or gained, gained is added from p, lost is subtracted from p)
18. is 1,750$
I am not entirely sure what interest periods are but I assume you can use this formula to find it. good luck man.

Step-by-step explanation: The bill cost $89.95 with a tip amount of 20% you would end up spending $107.94 if you are not splitting the bill
Answer: 107.94: The total you pay is 107.94

Total before the tip is 89.95
20% of 89.95 is equivalent to 0.20 x 89.95, which equals 17.99
add this tip, 17.99, to the price of the meal, 89.95.
17.99+89.95=107.94

Write an exponential function to model the data in each table. Identify the growth or decay factor. (23) Picture
The model of the exponential functions show that
23: table 1 is a decay with a rate of 50%24. tables 2 is a growth with a rate of 10%How to write exponential function to model the data in each tableConsidering the given problem, f(x) = a(b)^x
the starting = a
the base = b
the exponents = x
23. Table 1
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
4 = a * (b)^0
4 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
2 = 4(b)^1
b = 2/4
b = 0.5
for decreasing rate, b = 1 - 0.5 = 0.5
rate, r = 50%
24. Table 2
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
100 = a * (b)^0
100 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
110 = 100(b)^1
b = 110/100
b = 1.10
for increasing rate, b = 1 + r = 1.10, r = 0.10
rate, r = 10%
The base is what determines exponential growth or decay

A runner completed a 26.2-mile marathon in 210 minutes.
- Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth.
- Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth.
- Another runner says, "I averaged 10-minute miles in the marathon." Is this runner talking about the unit rate described in part (a) or in part (b)?
- Explain your reasoning.
Answer:
0.123 miles per min
8 mins per mile
The runner is talking about part (b)
Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b
Step-by-step explanation:
Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute
And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.

PLEASE HELP THIS WAS DUE FRIDAY BUT I DIDNT HAVE TIME
THANK YOU FOR YOUR HELP
Answer:
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
Step-by-step explanation:
-1 2/3= -1.67 min
-1 3/8 = -1.375 min
so 7he least to greatest is
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
The ordered list from least to greatest is -1.8 < -1 2/3 < -1.45 < -1 3/8
What is a mixed fraction?
A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder.
So, a mixed fraction is a combination of a whole number and a proper fraction.
According to the given question:
Gina's relative time list is [tex]-1\frac{2}{3}[/tex] , -1.45, -1.8, [tex]-1\frac{3}{8}[/tex]
Converting mixed fractions to decimal forms to make comparison easy.
-1 2/3 = -1 + 2/3 = - 1.6 min
-1 3/8 = -1 + 3/8 = -1.375 min
Hence the new list is - 1.6, - 1.45, - 1.8, - 1.375
Arranging from least to greatest as follows
-1.8 < - 1.6 < - 1.45 < - 1.375
- 1.8 < -1 2/3 < -1.45 < -1 3/8
