Here's the solution :

perimeter of equilateral triangle = 3 × x = 3x

perimeter of square = 4 × (x + 10)

now, according to above statement :

permission (square) = 3 × perimeter (triangle)

that is :

therefore, side of triangle = 8 cm

Answer:

Let the side of the equilateral triangle = x

so the side of the square =  x+10

The perimeter of the triangle = 3x

and the perimeter of the square = 4(x+10)

condition : the perimeter of the square is 3 times the perimeter of the triangle.

so, 4(x+10) =  3*(3x)

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

4x+5=x+8

4x-x = 8-5

3x=3

x=1

Answer:

1

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20

Answer:

The Answer is 30 questions in total.

Step-by-step explanation:

1. The first thing you would want to do is to break down this question.

For every 6 questions, this is 20% of the test done.

2. You now would want to divide 100% (the full amount on the test) by 20%.

100%/20% = 5

3. Now, multiply both to get your answer.

6·5= 30

20%x5= 100%.

Therefore, the total amount of questions on the test is 30 questions.

Answer: B

Step-by-step explanation: Hope this helps!

he got a one time thing of 75 coins and now gets 20 coins for each month which explains 20x. (X being the number of months)

The equation that could be used for determining the y should be option B y = 20x + 75

Since dad gave him 75 coins. each month he will add 20 coins.

Here we assume a number of months be x

So, the equation is

y = 20x + 75

Therefore, we can conclude that The equation that could be used for determining the y should be option B y = 20x + 75

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If out of 28 students, 12 students packed their lunch.

The number of students who packed their lunch out of 336 students is 144 students.

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 3 hours.

1 mile in one hour.

We have,

In a class of 28 students, 12 students packed their lunch.

We can write this as:

28 students = 12 students packed lunch ______(1)

We have to make 28 students into 336 students.

This can be done by multiplying 12 on both sides of the equation (1)

Multiply 12 on both sides.

12 x 28 students = 12 x 12 students packed lunch

336 students = 144 students packed lunch

Thus,

The number of students who packed their lunch out of 336 students is 144 students.

Supposing linear functions for both cases, it is found that employees at Hideaway pizza make $250 more at the end of the month.

--------------------

The salary, in dollars, for x days of work at Hideaway pizza is of:

[tex]S_h(x) = 300 + 40x[/tex]

At Red & Blue's, it is of:

[tex]S_r(x) = 500 + 25x[/tex]

A month is 30 days, so, the salaries are:

[tex]S_h(30) = 300 + 40(30) = 300 + 1200 = 1500[/tex]

[tex]S_r = 500 + 25(30) = 500 + 750 = 1250[/tex]

1500 - 1250 = 250, thus:

Employees at Hideaway Pizza make $250 more at the end of the month.

10.5 is the radius

1626 is the diameter

The answer is 29

when we see angles like that we will use a property of a parallelogram

which means

2x-10 angle plus 4x+16 angle equal to 180 degrees

let's find out

(2x-10)+(4x+16)=180

6x+6=180

6x=174

x=29

Have a great day

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Answer:75 ithink

Step-by-step explanation:

Step-by-step explanation:

the derivative of an inverse function is

1/f'(f^-1(x))

f'(x) = -6x²

f^-1(7) is solving the original function equation for x under the knowledge that y = 7

7 = 5 - 2x³

2 = -2x³

-1 = x³

=>

x = -1

f'(-1) = -6×(-1)² = -6×1 = -6

so,

(f^-1)'(7) = -1/6
