Step-by-step explanation:
In wrestling you score points by performing certain moves. Escapes, takedowns, and nearfalls are moves you can perform to score points. An escapeis worth 1 point, a takedown is worth 2 points, and a nearfall is worth 3 points. Anahi scored a total of 240 points by completing 100 moves. She had 4 times as many takedowns as escapes. How many escapes, takedowns and nearfalls did she have?
Answer: Im gonna take you down like a sweet muffin.
The number of escapes, takedowns and nearfalls Anahi have is 6, 24 and 70 respectively.
How many escapes, takedowns and nearfalls did she have?escape is worth 1 point,
a takedown is worth 2 points, and
a nearfall is worth 3 points.
escape = x
takedown = y
nearfall = z
x + y + z = 100. (1)
x + 2y + 3z = 240. (2)
y = 4x. (3)
substitute (3) into both equation
x + 4x + z = 100
x + 8x + 3z = 240
5x + z = 100. (4)
9x + 3z = 240. (5)
Multiply (4) by 3
15x + 3z = 300 (6)
9x + 3z = 240. (5)
Subtract (5) from (6) to eliminate z
6x = 60
x = 60/6
x = 6
Substitute into (3)
y = 4x
y = 4(6)
y = 24
Therefore, from (1)
x + y + z = 100.
6 + 24 + z = 100
30 + z = 100
z = 100 - 30
z = 70

A 9-inch candle burns down in 12 hours. After how many hours will it have burned
3 3/8 inches?
Answer:
4.5
Step-by-step explanation:
Use a proportion.
3 3/8 = 3.375
9 inch is to 12 hours as 3.75 inches is to x hours.
9/12 = 3.375/x
3/4 = 3.375/x
3x = 4 * 3.375
x = 4 * 1.125
x = 4.5
Answer: 4.5 hours
Using rate if a 9-inch candle burns down in 12 hours, the amount of hours it have burned 3 ³/₈ inches is 4 ¹/₂ h
What is a rate?Rate is the amount per unit time of a substance
Since a 9-inch candle burns down in 12 hours. To determine after how many hours will it have burned 3 ³/₈ inches, we proceed as follows.
.
First, we calculate the rate at which it burns which is given as r = Length of candle/time
Since
Length of candle = 9 in andtime = 12 hoursSubstituting the values of the variables into the equation, we have that
r = Length of candle/time
r = 9 in/12 h
r = 3/4 in/h
To determine how many hours it would have burned 3 ³/₈ in, we have that
rate, r = Length/time
time = Length/rate
Since
Length = 3 ³/₈ in = 27/8 in andrate = 3/4 in/hSubstituting the values of the variables into the equation, we have that
time = Length/rate
= 27 in/8 ÷ 3/4 in/h
= 27/8 in × 4/3 h/in
= 9/2 h
= 4 ¹/₂ h
So, it will have burned for 4 ¹/₂ h

Step-by-step explanation:
Answer:
7 to the power of 13
Step-by-step explanation:
Step 1 - 7 to the power of 8 (7 x 8 = 56)
Step 2 - 7 to the power of 5 (7 x 5 = 35)
Step 3 - (7 x 8) + (7 x 5) = 91
Step 4 - Divide 91 by 7
Then your answer would be 7 to the power of 13
A train leaves Zurich at 2240 and arrives in Vienna at 07 32 the next day. Work out the time taken.
The answer is 8 hours 32 minutes
But can someone properly explain how
Step-by-step explanation:
Okay so, 22:40 is 10:40pm
07:32 is am
Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)
Then there would be 8 hours alone (11 to 7 is 8 hours)
So it takes 8 hours and 52 minutes from 10:40pm to 7:32am

Find the area of the shaded portion.
Answer:
Step-by-step explanation:
There's a fact hidden in the diagram that if you do not know it, the problem will be very difficult to solve. The fact is this. If a 60 degree angle is enclosed by the hypotenuse and the other of side of the 60 degree angle. the hypotenuse is 2 times the length of the side.
In this case the hypotenuse is 12. The given side is 6. The third side of the right triangle is 12^1 - 6^2 = 144 - 36 = 108
The length of the third side is sqrt(108) = 6*sqrt(3)= 10.39
The area of one of the triangles is 1/2 * 6 * 10.39 = 31.18
The area of two of the triangles is 2 * 31.18. = 62.36
Now you you have to do is find the area of the unshaded sector
Area = given angle / 360 * pi * r^2
Area = 120/360 * 3.14 * 6^2
Area = 37,68
The area of the shaded part = the area of the 2 triangles - the unshaded sector
The area of the shaded part = 62.36 - 37.68 = 24.68

look in explanation
Step-by-step explanation:
Seeing as most of your answers are wrong, I'll start from the beginning.
a rational number is a number that can be expressed as a fraction.
an integer is a whole number.
an irrational number is a number that cannot be expressed as a fraction.
an integer is also always a rational number.
Using this, we can sort the values.
-77/11 can be simplified as -7, which is an integer.
the square root of 144 is 12, which is an integer.
0.25 is a decimal that can be expressed as a fraction, which makes it a rational number that is not an integer.
the square root of 20 is a value that cannot be expressed as a fraction, which makes it irrational.
17/4 is a fraction that is not a whole number, which makes it a rational number but not an integer.
finally, 2*the square root of 10 is irrational.

Step-by-step explanation:
Point Slope Form: (y - y₁) = m(x - x₁)
4. y - 4 = 0.8(x - 2)
- To make it slope-intercept form
y - 4 = 0.8x - 1.6
y = 0.8x + 2.4
5. (Use slope finding formula) 4 - 10 / -2 - (-5) = 2
y - 4 = 2(x + 2)
- To make it slope-intercept form
y - 4 = 2x + 4
y = 2x + 8
