What is the missing side length of a right triangle with legs 4 and 6 centimeters
Answer:
7.21 cm.
Step-by-step explanation:
4² + 6² = x²
16 + 36 = x²
52 = x²
[tex]\sqrt{52} = x[/tex]
7.21 cm.
Check
The third side of a triangle is greater than the difference and less than the sum of the lengths of the two given sides. 6 - 4 = 2 and 6 + 4 = 10
So the third side is between 2 and 10.

Kate Sanders, a researcher in the department of biology at IPFW University, studied the effect of agriculture contaminants on the stream fish population in Northeastern Indiana (April 2012). Specially designed traps collected samples of fish at each of four stream locations. A research question was: did the differences in agricultural contaminants found at the four locations alter the proportion of the fish population by gender? Observed frequencies were as follows.a. Focusing on the proportion of male fish at each location, test the hypothesis that the population proportions are equal for all four locations. Use a .05 level of significance. What is the p-value and what is your conclusion?b. Does it appear that the differences in agricultural contaminants found at the four locations altered the fish population by gender?
Answer:
H0 : population proportion are equal
H1: population proportion are not equal

Given that r varies directly as t^3, and r=54 when t=3. Find t when r=250
Answer:
t = 5
Step-by-step explanation:
Given r varies directly as t³ then the equation relating them is
r = kt³ ← k is the constant of variation
To find k use the condition r = 54 when t = 3 , then
54 = k × 3³ = 27k ( divide both sides by 27 )
2 = k
r = 2t³ ← equation of variation
When r = 250 , then
250 = 2t³ ( divide both sides by 2 )
125 = t³ ( take cube root of both sides )
[tex]\sqrt[3]{125}[/tex] = t , that is
t = 5
The temperature of a substance in an experiment changes by -7.5°F from 8 a.m. to 2 p.m. At 5 p.m., the temperature is 43.5°F. It is 1/3 of what the temperature was at 2 p.m. What was the temperature at 8 a.m. of the substance?
Answer:
ok
Step-by-step explanation:
Answer:
138* F
Step-by-step explanation:
If 43.5 is 1/3 of what it was at 2 p.m. then we need to multiply the equation by three where we get 130.5. Since it changed by -7.5 we have to add 7.5 to get our final answer of 138 degrees at 8 P.M.

What is the name of the property illustrated below?
3(x+4)=(x+4)+3
a :associative property of addition
b :commutative property of addition
c: associative property of multiplication
d: commutative property of multiplication
Step-by-step explanation:
I think you made a mistake with the equation.
because that property, that you presented, did not exist.
but
3(x+4) = (x+4)3 exists
and it is the commutative property of multiplication (a×b = b×a).

What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given that, Irma is just learning to play the Happy Fairies video game.
In the game, based on the taking care of fairies, players gain and lose points.
Initial point Irma had = -5 points
Fairy fell over in the wind and she got -3 points.
Final point = -5 + -3
= -5 - 3
= -8
Hence the total points now is -8.
