Answer: 13/50

Step-by-step explanation: To add these 2 fractions together, 2/10 + 6/100, we need a common denominator. The common denominator is simply the least common multiple for the 2 denominators which in this case is 100.

In order to get a denominator of 100 in the first fraction, we must multiply our denominator of 10 by 10.

The problem is we can't just multiply the denominator of a fraction bt 10 because that changes its value.

However if we also multiply the numerator of the fraction by 10, we're actually multiplying the fraction by 10/10 which is 1 and when we multiply anything by 1, it doesn't change its value. So our first fraction becomes 20/100. Notice that 20/100 has the same value as 2/10.

Since 6/100 already has a denominator of 100, we leave it.

So we have 20/100 + 6/100.

To add like fractions, we add across the numerators and keep the same denominator.

So 20/100 + 6/100 gives us 26/100.

Since the fraction 26/100 is not in lowest terms, we divide the numerator and denominator by 2 to get the equivalent fraction 13/50.

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

it consists of a rectangle, dimensions L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2

</span>then, you have one half of the area of the circle that has diameter R = 3ft - radius will be r = 1.5ft the area of that half will be:

Ac = r^2 $\pi$ / 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2
= 7.065 ft^2/ 2
= 3.5325ft^2

A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2

<span>At the rate of $2 per square foot, the cost will be:
$ 15.5325*2 = 31.07 </span>

Pachacha [2.7K]

Solving this problem needs the distance formula of point to a line.

The formula is:

distance = | a x + b y + c | / √ (a^2 + b^2)

So we are given the equation: y = 2 x + 4

Rewriting this would be: y – 2 x – 4 = 0 -> a = -2, b = 1, c = -4

We are also given the points:

(-4, 11) = (x, y)

Plugging it in the distance formula at points (x, y):

distance = | -2 * -4 + 1 * 11 + -4 | / √ [(- 2)^2 + (1)^2]

= 15 / √ (5)

= 6.7

So the tree is approximately 6.7 feet away from the zip line.

Decrease means to go down or take away, therefore in a mathematical equation, it would be represented by a negative integer.

Change could be positive or negative

each is a singular description word
