Answer:
0.2(2 tenths) times 0.3(3 tenths) = 0.06
Step-by-step explanation:
2 times 3 equals 6.
The 6 would have a 0 before it because you are using multiplication. If you were using addition, it would be 0.5(5 tenths) since you are adding tenths.
C. Karla says that to solve the equation you first subtract 15 and then divide by 10.
Karla is given the equation 10x + 15 = 20 to solve. She says the solution is 1/2
10x + 15 = 20
10x = 20 - 15 (subtract 5)
10x = 5 (divide by 10)
x = 5/10 = 1/2

![x +( x + 2) +( x + 4) = x + (x + 2)](https://tex.z-dn.net/?f=x%20%2B%28%20x%20%2B%202%29%20%2B%28%20x%20%2B%204%29%20%3D%20x%20%2B%20%28x%20%2B%202%29)
![3x + 6 + 9 = 2x + 2](https://tex.z-dn.net/?f=3x%20%2B%206%20%2B%209%20%3D%202x%20%2B%202)
![3x + 15 = 2x + 2](https://tex.z-dn.net/?f=3x%20%2B%2015%20%3D%202x%20%2B%202)
![x + 15 = 2](https://tex.z-dn.net/?f=x%20%2B%2015%20%3D%202)
![x = - 13](https://tex.z-dn.net/?f=x%20%3D%20%20-%2013)
Since x=-13 the intergers are
![- 13](https://tex.z-dn.net/?f=%20-%2013)
![- 11](https://tex.z-dn.net/?f=%20-%2011)

Represent the function as
![x + x + 6 = 44](https://tex.z-dn.net/?f=x%20%2B%20x%20%2B%206%20%3D%2044)
![2x + 6 = 44](https://tex.z-dn.net/?f=2x%20%2B%206%20%3D%2044)
![2x = 38](https://tex.z-dn.net/?f=2x%20%3D%2038)
![x = 19](https://tex.z-dn.net/?f=x%20%3D%2019)
The shorter piece should be 19 inches.

Answer: YES! (Option A)
Reasoning:
• A bisector is a Geometric figure line or line segment that intersects a line or shape at the midpoint and divides it into 1/2 or a 1:1 ratio.
• Therefore, a perpendicular bisector is a bisector that intersects a Geometric figure at 90°.
• Because a bisector divides a figure into two equal parts, a perpendicular bisector splits a figure into two congruent parts with a 90° intersection.
• Therefore, with perpendicular bisector RT, segments UR and RS are congruent.
• So, segment UR = 17, which means that segment RS = 17 because the bisector splits it into two halves or congruent parts.
Answer:
≈ 14%
Step-by-step explanation:
percent increase is calculated as
× 100%
Increase = 16489 - 14523 = 1966 , then
percent increase =
× 100% =
≈ 14% ( to nearest percent )
