Given that the perimeter of the equilateral triangle below is 63 , solve for x

1 answer:

8 0

An equilateral triangle has 3 equal sides with 3 equal angles.

Let x be the length of a equilateral triangle.

x + x + x = 63

3x = 63

x = 63/3

x = 21

The student council is selling cupcakes at the school play. The cost to make the cupcakes is a fixed $75 plus $0.17 per cupcak

dedylja [7]

Answer:

C = 75 + 0.17x and R = 2x

2x - (75 + 0.17x) > 0

x ≥ 41

Step-by-step explanation:

The cost to make the cupcakes is a fixed $75 plus $0.17 per cupcakes made and the selling price of each cupcake is $2.00.

Part A: Now, the equation for the cost, C, for making x cupcakes is

C = 75 + 0.17x ......... (1)

Again the equation for the revenue, R, from selling x cupcakes is

R = 2x ............ (2)

Part B: So, the inequality that could be solved to find the number of cupcakes, x, that must be made and sold to make a profit is

R - C > 0

2x - (75 + 0.17x) > 0 ......... (3)

Part C: Solving inequality (3) we get

(2 - 0.17)x > 75

⇒ x > 40.98

⇒ x ≥ 41 {Since, x can not be a fraction}

Let f be defined as shown.<br> What is f^-1(1)?

FinnZ [79.3K]

Answer:

From the above image when the input of f(x) is 9 the output is 1

So f^-1(1) is just the reverse when the input is 1 the output is 9

So f^-1(1) = 9

Please help me..make it right..

mr_godi [17]

Answer: 8/9

Step-by-step explanation:

The common multiple they all share is 18, so change the denominator to that for all the fractions.

2/3 = 12/18

13/18 = 13/18

7/9 = 14/18

5/6 = 15/18

The next answer would be 16/18 which is equivalent to 8/9

the greatest common divisor of positive integers $m$ and $n$ is $8$. the least common multiple of $m$ and $n$ is $112$. what is

Tasya [4]

Given the greatest common divisor and the least common multiple, the least possible value of mn is 896

<h3>How to determine the least possible value of mn?</h3>

The given parameters are:

M and N are positive integers

Greatest common divisor = 8

Least common multiple = 112

As a general rule;

The product of the greatest common divisor and the least common multiple of numbers represent the product of the numbers

This means that

mn = Greatest common divisor * Least common multiple

So, we have

mn = 8 * 112

Evaluate

mn = 896

Hence, the least possible value of mn is 896
