Answer:
46080 ft²
Step-by-step explanation:
Given :
Scale :
1 in = 4 feets
Recall :
I foot =. 12 inches
Length of drawing = 4 feets
Length of drawing in inches = 4 * 12 = 48 inches
Width of drawing = 5 feets
Width of drawing in inches = 5 * 12 = 60 inches
Actual length of pool = 48 * 4 = 192 feets
Actual width of pool = 60 * 4 = 240 feets
The actual area of the pool :
Length * width
192 feets * 240 feets = 46080 ft²
Answer:
y = 1/3x - 2
Step-by-step explanation:
We are asked to find the equation of a line with two points
Step1: find the slope
m = (y_2 - y_1)/(x_2 - x_1)
( 0 , -2) (6 , 0)
x_1 = 0
y_1 = -2
x_2 = 6
y_2 = 0
Insert the values
m = ( 0 - (-2)/ (6 - 0)
m = ( 0 + 2)/(6 - 0)
m = 2/6
m = (2/2)/(6/2)
m = 1/3
Step 2 : substitute m into the equation of line
y = mx + c
y = intercept y
m = slope
x = intercept x
c = intercept
y = 1/3x + c
Step 3: sub any of the two points
Let's pick ( 6 ,0)
x = 6
y = 0
Insert the values into
y = 1/3x + c
0 = 1/3(6) + c
0 = 1*6/3 + c
0 = 6/3 + c
0 = 2 + c
c = 0 - 2
c = -2
Sub c = -2
y = 1/3x - 2
The equation of the line is
y = 1/3x - 2
Answer:
I think its 8a because in a regular octagon we have 8 sides.
You can use base ten blocks to find 2.16/ 3 by using 7 base ten blocks and 2 base one blocks.
The value of the expression (1 + 13)2 - 2^9 is -484
<h3>How to evaluate the expression?</h3>
The expression is given as:
(1 + 13)2 - 2^9
Evaluate the expression in the bracket
(1 + 13)2 - 2^9 = (14)2-2^9
Remove the bracket in the expression
(1 + 13)2 - 2^9 = 28-2^9
Evaluate the exponent in the expression
(1 + 13)2 - 2^9 = 28-512
Evaluate the difference in the expression
(1 + 13)2 - 2^9 = -484
Hence, the value of the expression (1 + 13)2 - 2^9 is -484
