In the scale used on a blueprint .1\4 inch represents 2 feet,on the blueprint what is the length of a room with an actual length of 20 feet?

Cut diameter in half to find radius

9/2 = 4.5

radius = 4.5

This is the formula for area of a circle:

pi * radius^2

pi * 4.5^2

20.25pi

Now find pi:

20.25 * pi = 63.6

Answer:

63.6 cm is the area

Answer:

63.6

Step-by-step explanation:

1. A = πr²

2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5

3. Now that we know the radius, we plug it into our formula: A = π(4.5)²

4. Simplify: A = 3.14(20.25)

5. A = 63.62

6. Rounding to the nearest tenth makes your answer 63.6

Answer:

For part 1, it is true.

2h = 5 x 2 = 10

5 + 10 = 15

For part 2, I don't what your referring to, is it the 8h + 5 = 6h + 15?

Answer:

8h +5=6h+15

8 x 5 + 5= 6 x 5 +15

35= 50

= 35/50

= 7/10

Answer:

The intercept is 2 or (0,2) because that is where it intercepts on the Y axis

Answer:

(0,2)

Step-by-step explanation:

The y-intercept is just where the line passes through the y-axis or when x= 0.

Answer:

The answer is $60.45 :)

Step-by-step explanation:

1.) 9.30 x 6 = 55.8

2.) 9.30 (divided by) 2 = 4.65

3.) 55.8 + 4.65 = $60.45

4.) Max makes $60.45 every 6 1/2 hours.

its

= 4.1/100 × 30

= 41/1000 × 30

= 123/100

= 1.23%

Answer:

1.23

Step-by-step explanation:

Hey there !!!!!

4.1% of 30

if we solve it :

Y is 4.1% of 30

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 4.1% * 30

Converting percent to decimal:

p = 4.1%/100 = 0.041

Y = 0.041 * 30

Y = 1.23

therefore:

4.1% of 30 = 1.23

Step-by-step explanation:

(4z +9) + ( 9y - 2) =180

4z + 9y = 173 ....... Equation 1

The angles of triangle = 180

We miss one angle and in opposite of that angle is 135 so

( 5y +5 +4z +9)+135 = 180

5y + 4z + 149 = 180

5y + 4z = 31 ....... Equation 2

Subtract between two equations 1 & 2

4y = 142

y = 142/4

y = 35.5

Answer:

(the slope is 3/5)

Answer:

y = 130,000(1.03)ˣ

Step-by-step explanation:

The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.

The exponential function in terms of x and y is y = 130,000(1.03)ˣ

The exponential function is a mathematical function denoted by

y = abˣ

where a is the initial value (when x = 0)

and b is the multiplier (the growth or decay factor).

population starts from 130,000, so

Initial value a = 130,000.

A growth of 3% each year represents a growth factor of 1.03,

so after x years, the population y should be

y = 130,000(1.03)ˣ

Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Answer:

ok so you first point is the y intercept =5 plot this at 5 on the y axis/vertical line from there you plot your slope =1/2 you go up 1 and over 2

Answer: you calculate where the points are and place them in the coordinated spots

Step-by-step explanation:

When looking at coordinates, the first number is on the x axis(horizontal/ side to side line) and the second in on the y axis(vertical/ up and down line) then counting the lines of the point over to the given x axis number, then up the given y axis number

Answer:

= 10y − 6 is your answer

Step-by-step explanation:

option B is correct, 25y²-30y+9 is the product of (5y − 3)².

The combination of numbers, variables, and operators is known as Expression.

The given expression is (5y − 3)²

The process of determining the product of two or more numbers is Multiplication.

The expression is five times of y minus three to the power of two.

From algebraic identity we have (a-b)²=a²+b²-2ab

Now (5y − 3)²

(5y)²+3²-2(5y)(3)

25y²+9-30y

Twenty five y to the power of two plus nine minus thirty times of y.

25y²-30y+9 is the expression after product of  (5y − 3)².

Hence, option B is correct, 25y²-30y+9 is the product of (5y − 3)².

Answer: 0.18

Step-by-step explanation:

From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:

= 75% × 75% × 75% × 75% × 75% × 75%

= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4

= 729/4096

Answer:

blank = -11

Step-by-step explanation:

The given function is :

[tex]f(x) = (x^2 -6x+x)+20[/tex]

We need to find the number x such that it forms the complete square.

If x = -11, then it will becomes,

[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]

We can write it as follows :

[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)

We know that,

[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)

Comparing (1) and (2).

[tex]f(x)=(x-3)^2[/tex]

So, if we put the blank equals -11, then it will become the perfect square.
