Answer: Corresponding Parts of Congruent Triangles are Congruent.
Step-by-step explanation:
I had this question & this was the correct answer.
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.

Did you mention that multiplication is a shortcut for repeated addition?
Step-by-step explanation:
yes, in a similar way as division is a shortcut for repeated subtraction.
you do know, that you normally have to add the points win in a game, right ?
so, your score grows by 200 points each time you score.
that means
200
200
200
...
200
what do you think you do to get the total ? you add all the points.
you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.
but you did not have 200 hits, you only got 12 hits.
so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).
and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.
that is how multiplication works and helps with additions.
Answer:
its yes
bc yeah just......do it
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 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.

How many ways are there to arrange 1,2,3,4,5 in a line, such that n is not in the nth position?
For Example: 2,1,3,4,5 is not valid because 3 is the 3rd in the line but 2,1,4,5,3 is valid because none of the numbers are in their original position.
Answer:
256 ways
Step-by-step explanation:
Okay so n cannot be in the nth place, but there are 5 places available.
So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256
However, if that doesn't work, you could try 4! which is 4x3x2x1 = 24
Hope that helps :)
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

How many total points does Irma have now?
Irma has a total point of -8 now.
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.

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
0.4779 > 0.05
Step-by-step explanation:
What are the slope and y-intercept of the line? Question 2 options:
Slope = 6, y-Intercept = 170
Slope = -170, y-Intercept = 1020
Slope = 1020, y-Intercept = -170
Slope = 170, y-Intercept = 6
Answer: SLOPE=-170, Y-INTERCEPT = 1020
Step-by-step explanation:
Calculate the slope: Take any two points and find the changes in x and y:
I'll use (4, 340) and (6, 0):
Change in y (the rise) is (0 - 340) = -340.
The change in x is (6-4) = 2
The slope is the rise (y) over the run (x): -340/2 or -170.
The y-intercept is the value of y when x=0. The f=-data provided has a value for y at x=0: (0,1020). So the interecpt is 1020.
