Find the multiplier for 21.6% decay
Answer:
5pts
Step-by-step explanation:
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%.

This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the x-coordinate of one of the endpoints of the dilated segment
The x-coordinate of one of the endpoints of the dilated segment should be 8.
Calculation of x-coordinate:In the case when a coordinate point (x, y) should be dilated by a factor k, so the coordinate should be (kx, ky).Since the coordinate (4,1), so if this coordinate is dilated by a factor of 2 so the new coordinate points should be at (2(4), 2(1))Now
New point = (8, 2)

The height and the slant height of a cone are 24 cm and 25 cm respectively. Find the volume of the cone.
Pls answer with steps :)
Answer:
volume =183.26 cm³
Step-by-step explanation:
volume of a cone = 1/3πrl
l is the slant height
using; l²=h²+r²
r²= l²-h²
r²= 25²-24²= 625-576 =49
r=√49=7cm
volume = 1/3πrl = 1/3 (π×7×25)= 1/3 ×549.78
=183.26 cm³

Find slope intercept form.
(M=1/2) (6,3)
Answer:
y = (1/2)x
Step-by-step explanation:
Start with that form: y = mx + b. Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:
3 = (1/2)(6) + b. Thus, b = 0 and the desired equation is y = (1/2)x.
The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?
A. The correlation coefficient is close to zero.
B. Temperature is strongly correlated to the volume of ice cubes.
C. Temperature is the explanatory variable.
D. The data show a negative linear relationship.
The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
Types of correlation-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
The graph shows a volume of ice cubes versus temperature in degrees Celsius.
For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.
Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.
Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

each tank = 54 + (750÷ 1000) liter = 54.75L
so the capacity of the four tanks = 4x 54.75 = 219litre
Step-by-step explanation:
1) change 750 ml int litre which is equal 750÷1000 = 0.75L
2) add 54 +0.75

why is it important for jews to understand the characteristics of God
Answer:
To conclude, the characteristics of God provide a foundation by which Jews can look up to and mimic behaviour and develop good morals. They can come to understand and appreciate God, particularly as he is unseen, and this allows for them to be able to believe without question e.g. God is all knowing. G-d is all knowing and has a purpose for the world. This gives people faith to believe in God and wait for the Messianic Age to come, and have patience in God’s plan. However, it can be argued that there is no real point in having being taught characteristics of a being which can not be seen. With characteristics, some may argue that the concept of God can still not be understood, and the idea is unclear, particularly as the descriptions are supposedly by God himself, in which many Jews do not believe, as they are culturally and ethnically Jewish, rather than religiously Jewish.
