garik1379 [7]

The number of the cupcakes sold that day that were vanilla flavored is 172.

<h3>How do we calculate a number from a percentage?</h3>

The number of the cupcakes sold that day that were vanilla flavored can be calculated using the following formula:

Number of vanilla flavored cupcakes sold = Total number of cupcakes sold * Percentage that were vanilla flavored .............. (1)

Substituting the relevant values into equation (1), we have:

Number of vanilla flavored cupcakes sold = 400 * 43% = 172

A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible
Charra [1.4K]

Answer:

The smallest possible length is 0.83m

Step-by-step explanation:

Given

Volume = 565L

Required

The smallest length of the tank

Since the tank is cubical, then the volume is:

Volume = Length^3

This gives:

565L= Length^3

Express as m^3

\frac{565m^3}{1000} = Length^3

0.565m^3 = Length^3

Take cube roots of both sides

0.8267m = Length

Rewrite as:

Length = 0.8267m

Approximate

Length = 0.83m

3x-8&lt;23 and -4x+26&gt;6
Papessa [141]

Answer:

3x-8<23 and -4x+26>6

x<31/3            x<5

Step-by-step explanation:

3x-8<23

Add 8 to both sides

3x<31

Then divide 3 to both sides

x<31/3


and -4x+26>6

Minus 26 to both sides

-4x>-20

You divide -4 to both sides

Keep in mind that everytime you divide a negative the inequality will change so > will be <

x<5
