A baker is making cupcakes. he has 36 pounds of dough. each cupcake is made from ⅙ pound of dough. how many cupcakes can be made
Paha777 [63]

Answer: 216 cupcakes can be made

Step-by-step explanation:

<u>Given information</u>

36 pounds of dough in total

⅙ pound of dough per cupcake

<u>Set variables</u>

Let x be the number of cupcakes that could be made

<u>Set equations from given information</u>

Total = unit × number

36 = (1/6) × x

<u>Multiply 6 on both sides to isolate [x] variable</u>

36 × 6 = (1/6) × x × 6

216 = 1 × x

\boxed{x=216}

Hope this helps!! :)

Whats the fraction 18/24 reduced to its lowest items?
asambeis [7]
Hello!

\sf Answer:

The fraction 18/24, reduced to its lowest terms, is: \boxed{3/4}
_____________________________

Divide both the numerator and the denominator by the GCD of 18 and 24, which is 6:

18 ÷ 6 = 3

24 ÷ 6 = 4

It's simplest form would be 3/4. This cannot be reduced further.

A composite figure has three congruent triangles removed from it.
Advocard [28]
16•16=256

A quarter is missing so 256/4=64

64•3=192 is the total square area.

When you find the area of a triangle you usually do (b•h)/2

Since this right here is equal triangles for both ways you can simply divide 192/2=96ft^2

grin007 [14]

Answer:

15,240,960 serial numbers

Step-by-step explanation:

Since no repeats are allowed and the order matters, the number of possible serial numbers is given by the product of the permutation of 4 out of 9 letters by the permutation of 4 out of 10 numbers:

n=\frac{9!}{(9-4)!}*\frac{10!}{(10-4)!} \\n=9*8*7*6*10*9*8*7\\n=15,240,960

There are 15,240,960 ways to generate a serial number.

kozerog [31]
Hello! One number is negative and the other one is positive. In this case, we should find the difference they are from 0 and add the numbers up. -11 is 11 units away from 0. 17 is 17 units away from 0. 11 + 17 = 28. The difference in temperature is 28 degrees Celsius.
