Answer:

23. \frac{4\sqrt{3} }{3}

24. \frac{7\sqrt{3}}{3}

25. 6\sqrt{3}

26. \frac{10\sqrt{3} }{3}

27.  14

28. 4\sqrt{3}

Step-by-step explanation:

To solve these i used SOHCAHTOA

sin=\frac{opposite}{adjacent}\\ cos=\frac{adjacent}{hypotenuse} \\tan=\frac{opposite}{adjacent}

23.

Find the missing side using Tangent

tan(30)=\frac{x}{4}

4*tan(30)=x

\frac{4\sqrt{3} }{3}

24.

Find the missing side using Tangent

tan(30)=\frac{x}{7}

7*tan(30)=x

\frac{7\sqrt{3}}{3}

25.

Find the missing side using Tangent

tan(30)=\frac{x}{18}

18*tan(30)=x

6\sqrt{3}

26.

Find the missing side using Tangent

tan(30)=\frac{x}{10}

10*tan(30)=x

\frac{10\sqrt{3} }{3}

27.

Find the missing side using Tangent

tan(30)=\frac{x}{14\sqrt{3} }

(14\sqrt{3}) *tan(30)=x

14

28.

Find the missing side using Tangent

tan(30)=\frac{x}{12}

12*tan(30)=x

4\sqrt{3}

Is 9e+2(e+5) and 11e+5 equivalent?
pentagon [3]

No,

9e + 2(e + 5) = 11e + 10

And 11e + 10 is not equivalent to 11e + 5

Suppose at another time you would like to use the same pancake recipe.
erma4kov [3.2K]

For the pancake recipe, the results of the conversion of all the ingredients of the recipe to use exactly 3/4 cup of milk is:

  • Milk = 3/4 cup
  • Flour = 1 cup
  • Baking powder = 1 tablespoon      
  • Salt = 0.5 teaspoons
  • Eggs = 1
  • Blueberries = 0.62 cups
  • Servings = 3

   

To convert the recipe to use exactly 3/4 cup of milk, we need to convert all the ingredients units. We can start with the cups of flour.  

Initially, we had the following amount of milk:

milk = 1 + 1/2 = 3/2\: cups

Before we needed 2 cups of flour for 1 1/2 cups of milk, now for 3/4 cups of milk we need the following cups of flour:  

flour = \frac{2\: flour}{3/2 \:milk}*3/4 \:milk = 1\: cup

We can convert the other ingredients with this amount of cup of milk.

<u>Tablespoons baking powder</u>

baking powder = \frac{2\: baking\: powder}{3/2 \:milk}*3/4 \: milk = 1\: tablespoon  

Hence, we need to use now 1 tablespoon of baking powder.

<u>Teaspoon salt </u>

salt = \frac{1\: salt}{3/2 \:milk}*3/4 \:milk = 0.5 \: teaspoon  

Therefore, we need now 0.5 teaspoons of salt.  

<u>Eggs</u>

eggs = \frac{2\: eggs}{3/2 \:milk}*3/4 \:milk = 1  

Then, we need 1 egg.

<u>Cups blueberries</u>

blueberries = \frac{5/4 \: blueberries}{3/2 \:milk}*3/4 \:milk = 0.62 \:cups  

Therefore, 0.62 cups of blueberries are needed now.

The new amount of serving (s) is:

s = \frac{6 s}{3/2 \:milk}*3/4 \:milk = 3

Hence, for 3/4 cup of milk we can make now 3 servings.

You can find more about the conversion factor here:
