Answer:
1/5
Step-by-step explanation:
The best way to think about this is on a number line. -4 would be on the left of 0 meaning it is less than 0 and is on the right side of 0 but it is less than 1.
<u>Assume the 3rd side is the hypotenuse:</u>
a² + b² = c²
c² = 12² + 15²
c² = 369
c = √369
c = 19.21 inches (nearest hundredth)
<u>Assume the 3rd side is not the hypotenuse:</u>
a² + b² = c²
12² + b² = 15²
b² = 15² - 12²
b² = 81
b = √81
b = 9 inches
<u>Difference between the two length:</u>
19.21 - 9 = 10.21 inches
Answer: 10.21 inches
Answer:
B. 3.52
Step-by-step explanation:
4.20+1.80=6.00
6.00 x .08 (8% tax)=.48 tax
6.00+ .48=6.48 total cost
10.00-6.48=3.52 change from a $10 bill
Given:
A rectangle has a length 5 meters more than five times the width.
The area of the rectangle is less than 100 meters squared.
To find:
The expression or inequality that represents all possible widths of the rectangle.
Solution:
Let x be the width of the rectangle.
Length of the rectangle is 5 meters more than five times the width.
Area of rectangle is
The area of the rectangle is less than 100 meters squared.
Divide both sides by 5.
It is true if one factor is negative and other is positive. So,
...(i)
...(ii)
Using (i) and (ii), we get
Therefore, the required expression or inequality for possible
widths of the rectangle is .
Surface area = base area + side area
= pi * 7^2 + pi * 7 * 27 = 238pi = 747.7 cm^2
