Answer:
{14, 47, 50}
Step-by-step explanation:
The three sides of a right triangle must satisfy
a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.
20, 48, 52
a² + b² = c²
20² + 48² = 52²
400 + 2304 = 2704
2704 = 2704
20, 48, and 52 represent the three sides of a right triangle.
40, 75, 85
a² + b² = c²
40² + 75² = 85²
1600 + 5625 = 7225
7225 = 7225
40, 75, and 85 represent the three sides of a right triangle.
14, 47, 50
a² + b² = c²
14² + 47² = 50²
196 + 2209 = 2500
2405 ≠ 2500
14, 47, and 50 do NOT represent the three sides of a right triangle.
13, 84, 85
a² + b² = c²
13² + 84² = 85²
169 + 7056 = 7225
7225 = 7225
13, 84, and 85 represent the sides of a right triangle.
14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.
The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds
Answer:
4 seconds
Step-by-step explanation:
fish broke the water's surface in 1 second and went back into the water at 5 seconds
∴ it was out of the water for 4 seconds

Whats the slope of the line?
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.

Find the midpoint of the line segment whose endpoints are the given points. (-24.6, 38.1) and (-25.7, -17.7)
Answer:
Midpoint is[tex](-25.15,10.2)[/tex]
Step-by-step explanation:
A line segment refers to line that has two endpoints.
Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.
Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]
Take the given points as follows:
[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]
Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]
[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]
Can someone help me I don't know what n represents
Answer:
n=7
Step-by-step explanation:
6(n-3) - 2n=10
Distribute
6n - 18 -2n = 10
Combine like terms
4n -18 = 10
Add 18 to each side
4n-18+18 = 10+18
4n = 28
Divide by 4
4n/4 = 28/4

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200
= 50 times

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters
