VLD [36.1K]3 years ago
3 0
1. You have that Karen made 40 cakes and she gives 1/5 to Andrew and 10% to Chris, then you have:

 40 cakes=5/5=1
 1/5 to Andrew⇒40x1/5=8
 10% to Chris=40x0.10=4

 1/5----8 
    x----4 

 x=4(1/5)/8
 x=1/10

 2. The fraction of the 40 cakes that she have left is:

 1-1/5-1/10

 Therefore, the answer is: 7/10

Write using exponential notation?<br> 5.5.2.2.2.2
inna [77]

Answer:

5 ^{2}  \times 2^{4}

Step-by-step explanation:

Multiplying 5 by itself is the same thing as raising it to the second power:

5 \times 5 = {5}^{2}  = 25

We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:

2 \times 2 \times 2 \times 2 = {({2}^{2})}^{2}  =  {2}^{4}  = 16

Since only multiplication is present, we can combine the two terms to get:

5^{2}  \times  {2}^{4}

Find the interior angle of a regular polygon which has 6 sides​
AveGali [126]

Answer:

120°.

Step-by-step explanation:

The sum of all interior angles in a polygon with n sides (n\in \mathbb{Z}, n \ge 3) is equal to (n - 2) \cdot 180^{\circ}. (Credit: Mathsisfun.)

The polygon here has 6 sides. n = 6. Its interior angles shall add up to (6 - 2) \times 180^{\circ} = 720^{\circ}.

Consider the properties of a regular polygon. (Credit: Mathsisfun.)

  • All sides in a regular polygon are equal in length.
  • All angles in a regular polygon are also equal.

There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be

\displaystyle \frac{1}{6}\times 720^{\circ} = 120^{\circ}.
