Answer:
41.6
Step-by-step explanation:
all you have to do is subtract one term from another and then you find the common diffrence for which in this case its 9.6
Find the volume of the candle using the formula for volume of a cylinder:
V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8
Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.
Now divide the volume of the block by the volume of a candle:
3240 / 217.8 = 14.88
Round to the nearest tenth = 14.9 candles.
Answer:
Equation is | x-20 | = 2
Min = 18
Max = 22
==================================================
Explanation:
x = number of strawberries
|x-20| = distance from x to 20 on the number line.
Absolute value is used to ensure the distance is never negative. This distance represents how far off from 20 we are.
For instance, let's say the package had x = 17 strawberries
|x-20| = |17-20| = |-3| = 3
We're 3 units away from the goal of 20
--------------------
Setting |x-20| equal to the error of 2 will help us find the min and max
|x-20| = 2
x-20 = 2 or x-20 = -2
x = 2+20 or x = -2+20
x = 22 or x = 19
The smallest amount is 19 strawberries, while the most is 22. This represents the min and max respectively.
Answer:
E. 800%
Step-by-step explanation:
Since,
u = 8d/h² __________ eqn (1)
Now, density (d) is doubled and usage (h) is halved.
Hence the new life (u'), becomes:
u' = 8(2d)/(0.5h)²
u' = 8(8d/h²)
using eqn (1), we get:
u' = 8u
In percentage,
u' = 800% of u
In words, the percentage increase in useful life of the equipment is <u>800%</u>.
To factor: Notice that when you factor it should turn out to be a binomial x binomial.
x^2-10x+25
When factoring you can look at the operation at the end right before the last digit. If the operation is positive then you will use the first operation in the binomial for factored number. For example the ending operation is positive and the first operation is subtraction so both binomial will be subtraction.
I know it would be factored (x-5)(x-5) and I can prove it by multiplying it out.
x^2 -5x-5x+25
x^2-10x+25
