Translate the following written expression into a mathematical expression. Then, find the expression's value when a = 186 and b
antoniya [11.8K]

Answer: The correct answer is option A: 6

Step-by-step explanation: We shall start by splitting the word problem into bits to ease our calculations.

We start with “the quotient of a and 6...” and that can be expressed as

a/6 where a equals 186, this becomes

186/6 and this equals 31.

Note that quotient means the result derived from dividing two numbers/values.

Next, “The difference of ... and b squared”

The missing part of this statement has been calculated as 31, so this can now be written as “The difference of 31 and b squared” where b equals 5 and b squared now equals 25. Hence what we have is the difference of 31 and 25

That is, 31 - 25 and that equals 6.

Therefore, the expression can now be written out as;

(a/6) - b^2

When a equals 186 and b equals 5, the answer is 6

The cupcake factory sells cupcakes in three different types of packages. The first type is a 3-pack. The second type is a 6-pack
bija089 [108]

Answer:

3-pack= 135 cupcakes

6-pack= 270 cupcakes

9-pack= 405 cupcakes

Step-by-step explanation:

Let's say that 3-pack = a, 6-pack =b and 9-pack = c

The company’s leaders want to divide the cupcakes so that 3-pack, 6-pack and 9-pack packages produced are the same. This translate to an equation of:

a=b=c

The factory has 810 cupcakes in total. The equation will be:

a*3 + b*6 + c *9= 810

3a + 6b + 9c = 810

If we substitute the 1st equation into the second(we can  put b=a and c=a), the equation will become

3a + 6b + 9c = 810

3a + 6(a) + 9(a) = 810

18a= 810

a=45

Using the first equation, we know that we have 45 packages of each kind.

If there are 45 packages of 3-pack, the number of cupcakes go into 3-package will be: 3*45= 135 cupcakes

If there are 45 packages of 6-pack, the number of cupcakes go into 6-package will be: 6*45= 270 cupcakes

If there are 45 packages of 9-pack, the number of cupcakes go into 9-package will be: 9*45= 405 cupcakes

A stick of butter in the shape of a rectangular prism has a length of 8 inches, a width of 3 inches, and a height of 3 inches. W
SVEN [57.7K]

Answer:

72in^3

Step-by-step explanation:

the information we know about the shape of the stick of butter:  

length = 8in

width = 3in

height=3in

The formula for the volume of a rectangular prism is:

volume=length*width*height

we find the volume by multiplying ll the measurements of the stick.

So we substitute the values to find the volume and we get the following:

volume=8in*3in*3in\\volume=72in^3

the volume of the stick of butter is 72in^3
