58% is about equal to 60%, 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Answer:
1176
Step-by-step explanation:
First, calculate the volume as if it was a full rectangle.
Volume formula:
length x width x height
16 x 6 x 21 = 2016 (this is the volume if this was a full rectangle)
Now to calculate the size of the missing part we do the same thing
10 x 6 x 14 = 840
To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle
2016 - 840 = 1176
I hope this helped :-)
Namely, how much is 2 and 1/2 of 2 and 3/8 then, well is just their product, let's first convert them both from mixed to "improper" and proceed.
Answer:
It isn't?
Step-by-step explanation:
Step 1:
x + 8y = 21
x + 8y - 8y = 21 - 8y
x = -8y + 21
Step 2:
(-8y + 21) + 8y = 21
-8y + 21 + 8y = 21
21 = 21
Answer:
All of them.
Step-by-step explanation:
Rational numbers are defined as the numbers that can be expressed as the ratio of two integers(a/b) where b must be a non-zero number. The rational numbers display a terminating characteristic and they also contain repeating, as well as, recurring digits. All the given numbers are rational as they can be written in the form of p/q.
23.429 = It can be written as a fraction. So, it is a rational number.
10 = 10 is a whole number and it can be written in the form of a/b i.e. 10/1. So, it is a rational number.
13 = 13 also can be written in ration form as 13/1. Therefore, it is also a rational number.
151 = It can be written as 151/1. Hence, it is a rational number.
8/7 = It is already mentioned in the form of a/b. So, it is a rational number.
-4.93 = since it is an integer, it will surely be a rational number.
