Answer: 672
1. You need to find the arena of the missing piece so with the 40 on top you will subtract 12 which will give you 28
2. To find the other side subtract 28-12 to get 16 then you will multiple then together to get 448
3. Now just Multiply 40 and 28 to get 1120
4. Subtract 1120 and 448 and you’ll get the answer of 672
Answer:
Step-by-step explanation:
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or {\displaystyle {\tfrac {a}{b}}}
b
a
, where a and b are both integers. As with other fractions, the denominator (b) cannot be zero. Examples include {\displaystyle {\tfrac {1}{2}}}
2

, {\displaystyle -{\tfrac {8}{5}}}−
5

, {\displaystyle {\tfrac {-8}{5}}}

−8
, and {\displaystyle {\tfrac {8}{-5}}}

2.32*103 = 2.39E3, or 2.39*10^3
This result is likely wrong because I first thought your 103 literally meant 103. Now it seems that you meant 10^3 (10 to the third power). So, ignore the above result and multiply again: 2.32*10^3. This is already in scientific notation.
4.2*10^4 is already in scientific notation.
4.2*10^(-2) is already in scientific notation.
5700=1.7*10^3 (answer in scientific notation)
6548000= 6.55*10^(-6) (in scientific notation)
The answer is 11.25 mm.
A diameter of a circle is twice of its radius: d = 2r ⇒ r = d/2
small circle large circle
radius: r1 radius: r2 = ?
diameter: d1 = 15 mm
⇒ r1 = d1/2 = 15/2 mm
Since t<span>he ratio of the radii of two circles is 2:3, we have:
r1 : r2 = 2 : 3
which can also be expressed as:
</span>
<span>
We know that r1 is 7.5, so let's implement it:
</span>
Let's multiply both sides of the by 3r2:
⇒
⇒
5 3/8 rounds to 5,
4 7/10 rounds to 5
Your estimated sum is 10
