How to find the scale factor tho ?

Answers

We'd need to figure out the side of the bigger pentagon, which is going to be messy, but we can do it!

The area of a pentagon equation is messy, and we need to solve for the side given the area, which would be sqrt((4*area)/((5(5+2sqrt(5)))^(1/2)) or sqrt((4*8)/((5(5+2sqrt(5)))^(1/2)) . We get this from the pentagon equation, multiplying both sides by 4 dividing  (5(5+2sqrt(5)))^(1/2)) from both sides, then square rooting that to get the side length

Plugging it in, we get 2 and some more, and we multiply that by 2 to get the bigger side length. Plugging that into the area equation, we get a=32 and 32-8=24

Solve for x, Show your work: 1/2 (16 - x) = -12 (x + 7)

Answers

You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8
First you need to multiply 1/2 by 16, then multiply 1/2 by x to get 8-1/2x=-12(x+7). Then you multiply-12 by x to get-12x an then you multiply-12 by 7 so your equation looks like this 8-1/2x=-12x+-84. Combine the like terms and divide by the number with the x and you have your answer

A 25-N net force is applied to a rolling cart and produces an acceleration of 5 m/s2.What is the cart's mass

Answers

Remember that Force= mass*acceleration.
Plug in the known values

25 = m* 5

Divide both sides by 5
5= m

Final answer: The mass is 5 kg

The mass of the cart is 5 kg

The calculation can be done as follows

Force= 25 N

Acceleration= 5 m/s²

The mass can be calculated as follows

Force= mass × acceleration

25= mass × 5

mass= 25/5

= 5 kg

Hence the mass of the cart is 5 kg

explain the difference in meaning between |-3| and -3

Answers

| -3 | and -3

the absolute value of a number is just how many spaces that number is from 0. So it is not negative because distance is not measured in negative values.. The absolute value of a number is positive. So |-3| = 3.

-3 just equals -3.

so the difference, I guess, is that -3 is negative but the absolute value of -3 is positive

The number is positive when measured in absolute value. So |-3| = 3. since distance cannot be calculated in negative quantities.

What is the number?

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

Two numbers are given:

|-3| and -3

As we know, the mod function has positive range.

Let f(x) = |x|

The range of the function is [0, ∞)

The value of |-3| will be 3 after removing the mod which is also called the absolute value of the mod function.

A number's distance from zero, or its absolute value, is expressed as the number of spaces.

Since distance cannot be calculated in negative quantities, it cannot be negative. A number is positive when measured in absolute value. So |-3| = 3.

Thus, the number is positive when measured in absolute value. So |-3| = 3. since distance cannot be calculated in negative quantities.

Answer: Hi!, i guess you want to know the final number of turtles.

if the original number is 450 and they triplied in one year, then after the first year you have 450*3= 1350 turtles.

this process happens for 5 years, it means that the turtles triplied 5 times, you can write this as: [tex]450*3*3*3*3*3 =  450*3^{5} =109350[/tex]

3:7ratio of blue and red chairs if there are 91 red chairs how many blue are there?

Answers

There are 39 blue chairs.

You can find this by setting up a proportional equation:

3/7 = x/91

Solve for x by cross-multiplying:
7x = 91*3
7x = 273
7x /7 = 273 /7
x = 39

So, there are 39 blue chairs if there are 91 red chairs.
