The required multiplier for 21.6% decay is 78.4%.
Given that,
To find the multiplier for 21.6% decay
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay = 1 - r
Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%
Thus, the required multiplier for 21.6% decay is 78.4%.

Find the measure of the missing angle.
56
Answer:
34 degrees
Step-by-step explanation:
angles on a straight line add up to 180 degrees so over here the middle angle as we can see is 90 degrees so we add that to the 56 degrees. From adding them we get 146. 180 -146 is 34 degrees and that is our answer. :)

Consider the sequence of steps to solve the equation: 2(x – 4) + 6x = 9x – 10
Given = 2(x - 4) + 6x = 9x - 10
Step 1 = 2x - 8 + 6x = 9x - 10
Step 2 = 2x + 6x - 8 = 9x - 10
Step 3 = 8x - 8 = 9x - 10
Step 4 = 8x – 8x - 8 = 9x - 8x - 10
Step 5 = 0 - 8 = x - 10
Step 6 = -8 = x - 10
Step 7 = -8 + 10 = x - 10 + 10
Step 8 = 2 = x + 0
Step 9 = 2 = x

Complete the table below to find solutions to the linear equation y=5x−5.
Use parentheses when entering ordered pairs and do not enter spaces between numbers
The solution to the equation y = 5x - 5 is given by the ordered pairs
( 0 , -5 ) , ( 1 , 0 ) , ( 2 , 5 ) , ( 3 , 10 ) , ( 4 , 15 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y = 5x - 5 be equation (1)
On simplifying the equation , we get
Substitute the value of x = 0 in the equation , we get
y = 5 ( 0 ) - 5
y = 0 - 5
y = -5
So , the ordered pair is ( 0 , -5 )
Substitute the value of x = 1 in the equation , we get
y = 5 ( 1 ) - 5
y = 5 - 5
y = 0
So , the ordered pair is ( 1 , 0 )
Substitute the value of x = 2 in the equation , we get
y = 5 ( 2) - 5
y = 10 - 5
y = 5
So , the ordered pair is ( 2 , 5 )
Substitute the value of x = 3 in the equation , we get
y = 5 ( 3 ) - 5
y = 15 - 5
y = 10
So , the ordered pair is ( 3 , 10 )
Substitute the value of x = 4 in the equation , we get
y = 5 ( 4 ) - 5
y = 20 - 5
y = 15
So , the ordered pair is ( 4 , 15 )
Hence , the equations are solved

How many yards are in 126 feet?
1 yard = 3 feet
Kahleela starts the engine on her small private airplane. The engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. At idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. The height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. Find h when t = 5.5 minutes.
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.
Answer:
A. 3.1 feet is the answer i believe.........
Step-by-step explanation:
what is the answer to this question
Answer:
the height is 4
Step-by-step explanation:
it is a right triangle and also a perfect 3-4-5 right triangle
[tex] {3}^{2} + {h}^{2} \: equals \: {5}^{2} [/tex]
[tex]9 + {h}^{2} \: eqauls \: 25[/tex]
subtract 9 from 25
[tex] {h}^{2} \: equals \: 16[/tex]
then you square root 16

Pix diameter = Circumference
A group of students stood in a circle to play a game. The circle had a diameter of 22 meters.
Which measurement is closest to the circumference of the circle in meters?
A 34.54 m
B 1,519.76 m
C 379.94 m
D 69.08 m
Answer:
69.08m
Step-by-step explanation:
Circumference of a circle = πd where
d is the diameter of the circle
Given
diameter = 22metres
circumference of the circle = 3.14(22)
circumference of the circle = 69.08m
Hence the circumference of the circle is 69.08m

Answer:
1. C

3. A, B, C
4. C
5. B
6. C
Step-by-step explanation:
1. You can remember the name by just looking at their positions- they alternate and they're on the exterior
2. They are supplementary meaning they add to 180°, set the angle measures up to 180 and solve for x!
76 + 2x = 180
2x = 104
x = 52
3. Equilateral trinagles have these qualities
4. Those hashes on the sides of the triangles signify those sides are the same length- that means the angles opposite of those sides share the same angle measure. If you know two angles are 35, and the last angle is 2x, you can set up an equation:
35 + 35+ 2x = 180
70 + 2x = 180
2x = 110
x = 55
5. That square means a right angle which equals 90°, like question 4, you set up an equation!
90 + 5x + 5x = 180
90 + 10x = 180
10x = 90
x = 9
6. Set up a proportion.
12 : 30 // 12(x) = 30, x = 2.5
8 : y // 8(2.5) = y, y = 20

Mai gave half of her brownies, and then half a brownie more, to Kiran. Then she gave half of what was left,
and half a brownie more, to Tyler. That left her with one remaining brownie.
Can someone please help me with this problem, I really need help.
Answer:
x = 7
Step-by-step explanation:
all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last, multiply 3 1/2 by 2 and you will geet 7 as your final answer.
The answer would be 7!
You would take 1 and add 1/2 to it
= 1 1/2
Then, multiply by 2
= 3
Then add 1/2 to that
= 3 1/2
Then multiply 2 one more time
= 7
This is because Mai gave half of her brownie and then half more of her brownie to each person she gave it to
So you would add 1 + 1/2 and then multiply by 2
Since she did this to 2 people you would repeat one more time!
Hope this helped!

Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.
1. Which plane is faster?
Answer: First.
Step-by-step explanation:
Let's find the speed of the first airplane:
2800 ÷ 5 = 560 (miles per hour)
Let's find the speed of the second plane:
3885 ÷ 7 = 555 (miles per hour)
Thus, the first plane flies faster than the second.
