Answer:
I am not sure if you wrote the questions and its options correctly
Step-by-step explanation:
Putting fence around a rectangular garden would require it's perimeter the perimeter of almost all shapes can be done by adding all the sides
The answer is: 12+7+12+7 which also can be written as: 2(12+7)=38
Which is.. P=2(l+w)
Answer:
80:120
Step-by-step explanation:
20 x 4 = 80
30 x 4 = 120
Step-by-step explanation:
Let us consider the length of a line segment to be 'x'
Let the other line segment be 'y'
One line segment is 12 less than twice the length of other segment.
X = 2y - 12
The sum of both the lengths = 69cm
X + Y = 69
X = 69 - Y
Substitute the X value in the first equation
X = 2y - 12
69 - Y = 2Y - 12
- Y - 2Y = -12 -69
- 3Y = - 81
3Y = 81
Y = 81/3
Y = 27 CM
Length of One of the line segment is 27cm
The length of the other line segment 'x'
is
X= 2y - 12
X = 2(27) - 12
X = 54 - 12
X = 42cm
The length of the line segments are 42cm and 27cm.
Answer:
well it ended at 6:10 so practice started at 4:25
Step-by-step explanation:
just subract the 1:45 from 6:10 and you get 4:25
Answer:
t = sqrt(595/1289) or t = -sqrt(595/1289)
Step-by-step explanation:
Solve for t:
29/35 = 17/t^2 - 36
29/35 = 17/t^2 - 36 is equivalent to 17/t^2 - 36 = 29/35:
17/t^2 - 36 = 29/35
Bring 17/t^2 - 36 together using the common denominator t^2:
(17 - 36 t^2)/t^2 = 29/35
Cross multiply:
35 (17 - 36 t^2) = 29 t^2
Expand out terms of the left hand side:
595 - 1260 t^2 = 29 t^2
Subtract 29 t^2 + 595 from both sides:
-1289 t^2 = -595
Divide both sides by -1289:
t^2 = 595/1289
Take the square root of both sides:
Answer: t = sqrt(595/1289) or t = -sqrt(595/1289)
