Answers
Answer:
Step-by-step explanation:
A)
the sum of any two sides of a right triangle more than any other side
14+15>29, x is less than 29
14+x>15
x>1
15+x>14
x>-1
1<x<29
lets use Pythagorean Theorem
14^(2)+15^(2)=c^2
196+225=c^2
421=c^2
plusminus sqrt(421)=c
distance can't be negative, so:
c=sqrt(421)
c=20.5182845287
sqrt(421) is the largest possible right triangle side
1<x\(\leq\)sqrt(421)
B) as we can see from above, the largest possible length of the third side is 14/sqrt(421) or about 20.5182845287ft
C)sqrt(421) by 14 by 15

you want to buy some beans . a 6 - ounce package costs $2.16 . a 15 - ounce package costs $5.55 . a 26 - ounce package costs $9.10 . which package is the best buy
Answers
Answer:
26-ounce package
Step-by-step explanation:
Divide the cost for a 6-ounce and a 15-ounce package separately by the number of ounces listed above. 1 ounce for a 6-ounce package costs around $0.36 and 1 ounce for a 15-ounce package cost around $0.37. If we put the 26-ounce package in place, then each ounce cost $0.35. We want to buy the one that is the cheapest out of all of them and since the 26-ounce package cost more cheaper than the other packages, then you should buy the 26-ounce package since it is the best deal.

Answers
Answer:
x = 3Step-by-step explanation:
.02x + .02 = .08 solve for x
0.02x + 0.02 = 0.08
0.02x = 0.08 - 0.02
0.02x = 0.06
x = 0.06 : 0.02
x = 3
----------------
check
0.02 * 3 + 0.02 = 0.08
0.06 = 0.08 - 0.02
0.06 = 0.06
The answer is good
x = 3

Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
I hope that helps!
Answer:
6:59am
Step-by-step explanation:
1 hour and 33 minutes = 93 minutes
55 minute ride to museum
93+55=148
60 minutes in 1 hour
148 divided by 60 = 2 hours 46 minutes
Time Left: 9:41

11 1/9 - 3 2/3 step by step
Answers
Answer:
11 1/9 - 3 2/3 = 7 3/9
Step-by-step explanation:
First you have to turn 2/3 into ninths which would be 6/9. Then you have to turn 1/9 into 10/9 by giving one whole and turning it into a fraction. Then you have to subtract 10/9 - 6/9 = 3/9. Finally you have to subtract the wholes 10-3= 7 then your answer would be 7 3/9

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
The graph of the equation y=x²-2x-8 is a parabola. What is the equation of the axis of symmetry?
