ella bought some key chains and spent a total of 24 each key chain cost the same whole dollar amount she bought between 7 and 11 key chains how many key chains did ella buy?

Answers

Answer: there are 8 key chains Ella can buy.

Step-by-step explanation:

Since we have given that

Ella bought some key chain and spent a total of 24.

Each key chain cost the same whole dollar amount she bought between 7 and 11 key chains.

As we know that between 7 and 11, there is only 1 number which is factor of 24 i.e. 8

Hence, there are 8 key chains Ella can buy.
To solve this problem, you need to use a process of trial and error, and add up each number until you get 24 or above.  If you get above, it is wrong.  The only number that goes into 24 evenly is 8, so the answer is 8 keychains.

Which expression finds the measure of an angle that is coterminal with a 126° angle?126° + (275n)°, for any integer n
126° + (375n)°, for any integer n
126° + (450n)°, for any integer n
126° + (720n)°, for any integer n

Answers

Answer:

126° + (720n)°, for any integer n

Step-by-step explanation:

Coterminal Angles of an angle are the angles who share the same initial side and terminal sides.

Also, we can find the coterminal angle of an angle by adding or subtracting 360°. ( When angle is given in degree ),

For example, if Ф is an angle,

Then, its coterminal angles are,

Ф + 360 n, for an integer n,

Here, Ф = 126°,

Hence, its coterminal angles are,

126° + ( 360 n)°,

Since, n is an integer,

⇒ 2n is an integer,

So, the co-terminal angle of 126° can be written,

126° + ( 360×2n )°= 126° + ( 720n)°, for any integer n.
All the coterminal angles with 126° are 126 + k*360, being k an integer.

if you make k=2n

You find that 126° + 2n*360 also represent coterminal angles for 126°, so the answer is 126° + 720n


You are baking cupcakes for your class. There are 30 total students in your class and you have baked 15 cupcakes. Write andsolve an equation to find the additional number of cupcakes you need to bake in order to have 3 cupcakes for each student.
Write your equation so that the units on each side of the equation are cupcakes per student.
Equation:
= 3
Number of cupcakes: x=

Answers

The equation is 3=(x+15)/30 and the number of additonal cupcakes to be made is 75.

What is equation?

An equation is a relationship between the variables and constants representing how they are related to each other. It includes equal to "=" sign.

It is known that each student will have 3 cupcakes. So, right side of the equation will be 3.

After 15 cupcakes, x more cupcakes are needed. So, the total number of cupcakes is x+15.

Since there are 30 students, the number of cupcakes per student will be (x+15)/30

Determine the equation and solve it.

(x+15)/30=3

x+15=90

x=75

So, 75 more cupcakes are needed to be baked.
