Llen missed 5 targets, which is due to -50 divided by -10 equaling 5. I hope this clarifies! <3
Answer:
Step-by-step explanation:
a) According to the included image, the smaller section measures 16ft², and the larger section is 50 ft². The formula for the area of a square is side × side = side².
For the smaller section: Area = side²
16 = side²
side = √16 = 4 ft
For the larger section: Area = side²
50 = side²
side = √50
The overall length of the shed is the small area plus the large area = 4 + √50
The total length of the shed equates to 4 + √50
b) All square roots of integers unless they are perfect squares are irrational numbers, thus 4 + √50 is irrational. All such values fall within the set of real numbers, categorizing 4 + √50 as an irrational and real number.
Answer:
The cost for a 2,000 square foot house is 
Detailed explanation:
Recall that if two variables x and y vary directly, the relationship can be written as
or
.
Define:
x as the house area in square feet
y as the price of the house
Given point (1500, 300000)
Calculate proportionality constant k:

Insert values:

The direct variation equation is:

For x = 2000:
Calculate y:
Replace x in equation:


you can set this up with the equation;
x + (x + 42) = 138
start by combining like terms;
2x = 138 - 42
2x = 96
x = 96/2
x = 48
we've found x now plug it back into the original equation.
48 + (48 + 42) = 138
48 + 90 = 138
hope it helped...if you have any concerns just let me know:)
