You run around the perimeter of a baseball field at a rate of at most 12 feet per second. Which of the following are possible amounts of time that it takes you to run around the baseball field?
Answers
Answer: 79 seconds.
Step-by-step explanation:1) we have to calculate the lenght of the baseball field.
perimeter of the baseball field=2(radius)+lenght of a semicircle.
2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)
Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,
2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.
10 ft------------------------1 second
789,82 ft----------------- x
x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s

Triangles TUV and TWV are congruent triangles.
Angles U and W are corresponding angles, so they are congruent.
m<U = m<W
7x + 15 = 8x
Subtract 7x from both sides.
15 = x
m<U = 7x + 15 = 7(15) + 15 = 8(15) = 120

Company a charges 60$ plus 0.15 per mile company b charges 25$ per day or portion of a day .Jason has determined that it will cost him less to rent a car from company a for a weekend trip .is Jason's conclusion accurate?
Answers
Answer:
No
Step-by-step explanation:
A: C = 60 + 0.15m (C is total cost and m is no. of miles)
B: C = 25d (d is no. of days)
For a weekend trip, there are 2 days.
This means that the cost for B is 2*$25, which is $50.
It doesn't matter how many miles are driven for A because the cost will always be at least $60.
This means that B is cheaper and that Jason is inaccurate.

Determining the domain:
We know that the domain of relation consists of all the inputs or x-coordiantes of the ordered pairs.Thus, the domain of the relation is:
Domain R = {-4, 0, 2, 7}
Determining the range:
We know that the range of relation consists of all the outputs or y-coordiantes of the ordered pairs.Thus, the range of the relation is:
Range R = {1, 2, 7}
Please note that the duplicated elements in the domain or the range of the function are written only once.Therefore, option B is true.

(W, T, L, S) = (3, 2, 1, 4.1)
Step-by-step explanation:
For some number of wins (W), ties (T), and losses (L), the player's score will be ...
score = 2.2W +0.25T -3L
For 3 wins, 2 ties, and 1 loss, the player's score is ...

There are 64 species of animals in the metropolitan zoo
5/8 are from North America
1/4 are from Africa
The remaining are from South America
How many species are from South America
Answers
Answer:
8 species are from South America
Step-by-step explanation:
In order to find the answer to this, you need to make the denominators of the North American and African species the same.
To do this, multiply 1/4 x 2/2.
You would then get 2/8. This means 2/8 of the species are African
Since you now have the same denominator, add the fractions together, and the total amount of North American and African species is 7/8, leaving 1/8 for the South American species.
You would then divide 64 by 8 to see how much 1/8 is worth in terms of how many species, and would then get 8.

The average rate of change of g(x) over the interval [2, 8] is given by
(g (8) - g (2)) / (8 - 2)
In other words, it's the slope of the line through the points (2, g (2)) and (8, g (8)).
Use the definition of the function to evaluate it at the points in the numerator:
• 8 ≥ 4, so using the second piece, g (8) = -0.5(8) + 8 = 4
• 2 < 4, so g (2) = 5(2) + 1 = 11
Then the average rate of change is
(g (8) - g (2)) / (8 - 2) = (4 - 11) / 6 = -7/6
