Ari is designed a patio that will be 20 feet long and 16 feet wide. He makes a scale drawing of the patio using a scale of 1 inch to 4 feet. The ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to _ square feet ?

Answers

Answer:

the ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to 16 square feet.

Step-by-step explanation:

The actual area of the patio:

A = 20 feet long *16 feet wide = 320 square feet

The dimensions of the scale drawing are:

$20:4=5\ in\text{ and }16:4=4\ in,$

=> The scaled drawing area of the patio:

A = 5 in long * 4 in wide

= 20 square in

The ratio of the area of the scaled drawing to the actual area of the patio is:

$20:320=1:16$

the ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to 16 square feet.

16 square ft.

If 1 in is equal to 4 ft, then the area of a 4ft by 4ft square is 16 ft

Is 5 feet greater, less or equal than 60 inches?

Answers

Answer:

5 feet is equal to 60 inches.

Step-by-step explanation:

We know that

1 feet = 12 inches.

We'll use this relation to find whether 5 feet is greater, less or equal than 60 inches.

Since, 1 feet = 12 inches.

Hence, 5 feet should be equal to 5×12=60 inches.

Therefore, we can conclude that 5 feet is equal to 60 inches.

5 ft is equivalent to 60 inches because there are 12 inches in a foot. Because there are 5 feet, you would multiply 5 and 12.

What is the rate of increase for the function f(x)= 1/3(^3 sqr root 24)^2x

Answers

The rate of increase for the function $f (x) = (1)/(3)( \sqrt[3]{24}) ^(2x)$ by using formula and identity are,

⇒ $f ' (x) = \frac{4}{\sqrt[3]{3} }$

Using formula and identity are,

$(dx^n)/(dx) = nx^(n - 1)$

And, $(a^x)/(a^y) = a^(x - y)$

Given that,

The function is defined as,

⇒ $f (x) = (1)/(3)( \sqrt[3]{24}) ^(2x)$

We have to find the rate of increase of the given function.

⇒ $f (x) = (1)/(3)( \sqrt[3]{24}) ^(2)x$

Differentiate the function with respect to x,

⇒ $f' (x) = (1)/(3)( \sqrt[3]{24}) ^(2)$

Then, we get;

⇒ $f ' (x) = (1)/(3) (\sqrt[3]{2* 2* 2* 3} )^2$

⇒ $f' (x) = (1)/(3) (2)^2 (3)^{(2)/(3) }$

Using the identity $(a^x)/(a^y) = a^(x - y)$ ,

So, the rate of increase of function is,

⇒ $f ' (x) = \frac{4}{\sqrt[3]{3} }$

You must simplify the function first until the exponent becomes a flat x. Step 1 Leave 1/3 only that is the value a, initial value. You are looking for the base Step 2 Deal with the parentheses. Factor 24 and you get 2 and the cube of 3. Step 3 Separate the exponent (2) (x) Step 4 Now square each term in parentheses 2 squared and cube 3 squared 2 2 will be 4, the other expression means cube of 3 times cube of 3 and that is cube of 9 Step 5 Your base should be (4 cube of 9)

2x - 5y=-15
can someone walk me through this?

Answers

The equation given in the question has two unknown variables in the form of "x" and "y". The exact value of "x" and "y" cannot be determined as two equations are needed to get to the exact values of "x" and "y". This equation can definitely be used to show the way for determining the values of "x" in terms of "y"and the value of "y" in terms of "x". Now let us check the equation given.
2x - 5y = - 15
2x = 5y - 15
2x = 5(y - 3)
x = [5(y - 3)]/2
Similarly the way the value of y can be determined in terms of "x" can also be shown.
2x - 5y = - 15
-5y = - 2x - 15
-5y = -(2x + 15)
5y = 2x + 15
y = (2x +15)/5
= (2x/5) + (15/5)
= (2x/5) + 3
So the final value of x is [5(y -3)]/2 and the value of y is (2x/5) + 3.
