<span>In order for you to be able to solve this problem you have to first identify what the questions is asking. In this case it wants to know the approximation of what the semiannual income that Sarah will be able to draw.
To solve this you simply have to find the future value of her investment prior to retirement and use the as her investment amount upon retirement.
<span>I hope it helps, Regards. </span></span>
Answer: 3
Step-by-step explanation:
(32/36) / (9/36) = 3 with a Rest of 5/36
Answer:
D
Step-by-step explanation:
So we have the equation:
And we want to find out which of the answer choices is <em>not</em> equivalent.
Thus, let's go through each of the choices.
A)
We have:
This is correct.
Our original equation can be written as:
And if we multiply straight across:
We'll get choice A. So choice A is correct.
B)
We have:
This is also correct.
From our original equation:
If we multiply the first term together:
We'll get choice B. So, choice B is correct.
C)
We have:
This is correct as well.
If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:
So, C is also correct.
D)
We have:
Note that this is not correct.
This attempted to use the distributive property. However, the distribute property does <em>not work</em> for multiplication. For instance:
However:
So, choice D is not equivalent.
So choice D is our answer :)
If we evaluate it, we will get 30, in contrast to the 60 of the others.
Answer:
9 ≤ x ≤ 18
Step-by-step explanation:
Basically the minimum he should work is 9 hours (he will earn $105 per week) and the maximum he should work is 18 hours (he will earn $295 per week)
Answer:
Length of the rectangular prism = 4 meters
But other possible values = (-5meters or - 9 meters)
Step-by-step explanation:
The volume of a rectangular prism = Length × Width × Height
From the question above,
Length = x meters
Width = x - 1 meters
Height = x + 11 meters
Volume of the Rectangular prism = 180 cubic meters
Hence,
(x) × (x - 1) × (x + 11) = 180
We expand the brackets
(x)(x - 1) (x + 11) = 180
x² - x(x + 11) = 180
x² (x + 11) - x(x + 11) = 180
x³ + 11x² - x² + 11x =180
x³ +10x² - 11x = 180
x³ + 10x² - 11x -180 = 0
The above is a polynomial
We solve this polynomial to find x
x³ + 10x² - 11x -180 = 0
(x - 4)(x + 5) (x + 9) = 0
x - 4 = 0
x = 4
x + 5 = 0
x = -5
x + 9 = 0
x = -9
We are asked to find the various values for the length hence,
From the above question, we are told that
Length = x meters
Therefore, the length of this rectangular prism = 4 meters or -5 meters or -9 meters.
