Answer:

First we must learn to dissect a question.

<h3>Explanation:</h3>

Part 1

We can list our facts first:

  • Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
  • She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

6.5 \times 1.5 = 9.75 \: teaspoons

<h3>Part 2</h3>

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp

Find the area of a regular decagon with perimeter 100 units. Show all work.
Slav-nsk [51]
A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.

How do i work this out?
Karo-lina-s [1.5K]

She has 45% of the original amount left

<h3>Ratio and proportions</h3>

Fractions are written as a ratio of two integers

Given the following

Initial amount. = ∈4000


Amount given to her sister = 1/4 * 4000 = 1000

Amount given to her brother = 40% of 3000 = 1200

Amount left = 4000 - (1000+1200)

Amount left = ∈1800

Determine the percentage left

x * 4000 = 1800

x = 1800/4000

x = 0.45

x = 45%

Hence she has 45% of the original amount left

The quotient of number and -6 increased by two is 14​
Rama09 [41]

Answer:

x = -72

Step-by-step explanation:

Let the number be x.

The quotient of number and -6 is written as :

\dfrac{x}{-6}

Now the quotient is increased by 2 i.e.

\dfrac{x}{-6}+2=14

Now we can solve it as follows :

Subtract 14 from both sides,

\dfrac{x}{-6}+2-14=14-14\\\\\dfrac{x}{-6}-12=0\\\\\dfrac{x}{-6}=12\\\\x=-72

So, the value of x is equal to -72.
