these 15 colored pencils make up 20% of jordon's colored pencil collection.how many colored pencils does jordon have in his coll

dmitriy555 [2]

Answer:

75 coloured pencils

Step-by-step explanation:

Let's say Jordon has x total pencils.

We know that 20% of these x pencils is 15, so we have:

20% * x = 15

Remember that % is just "out of 100", so 20% = 20/100 = 0.20. Then:

0.20x = 15

x = 15 / 0.20 = 75

Jordon has 75 coloured pencils.

C) A manufacturer is making 100 times as many bows as Tess to sell in stores nationwide.

Luda [366]

1. Tess is making 12 bows.

2. 100 time as 12 bows = 100 × 12 = 1200 bows

3. In exponent form ; 12 × 10²

Given : Number of bows Tess makes = 100 times as the of x

Let the number of bows Tess makes be x

Thus the number of bows Tess is making is 12.

100 times as many means the number which we have calculated should be multiplied by 100.

thus the number as w2e have found out is 12

so multiplied by 100 will give us 1200

Exponential form means that the given number should be expressed in the form of 10.

As the number which is given to us is 1200n

thus in exponential form we can write it as 12 multiplied by 10 raise to the power as the number of zeros of present.

Here then number of number of zeros is 2

thus 10 raised to the power 2.

What is the area of the regular hexagon ABCEF? Explain your reasoning.

Reil [10]

Answer:

1350 $\sqrt{3}$ units²

Step-by-step explanation:

The regular hexagon consists of 6 equiangular triangles

The area (A) of a equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the side length )

Here s = 30 , then

A = $\frac{30^2\sqrt{3} }{4}$ = $\frac{900\sqrt{3} }{4}$ = 225 $\sqrt{3}$ units²

Thus the area of the regular hexagon is

area = 6 × 225 $\sqrt{3}$

= 1350 $\sqrt{3}$ units² ← exact value

≈ 2338.3 units² ( to 1 dec. place )
