Im gonna label the long side of a rectangle a and the smaller side b.
For the perimeter, 2a + 2b = 34
For the area, a x b = 66
if a is 11 and b is 6, the equation for perimeter would be 22 + 12 = 34.
So a = 11 and b = 6
Answer:
Longer side = 11
Shorter side = 6
Step-by-step explanation:
L x W = 66, then W = 66/L
2L + 2W = 34
substitute for W:
2L + 2(66/L) = 34
2L + 132/L = 34
multiply both sides of the equation by L:
2L² + 132 = 34L
divide both sides by 2:
L² + 66 = 17L
L² - 17L + 66 = 0
factor:
(L - 11)(L - 6) = 0
L = 11 or L = 6
if L = 11, then W = 6
if L = 6 then W = 11

Step-by-step explanation:
Work is said to be done when a force moves a body through a distance. This may be expressed as
work done = Force * distance
where
work done is measured in joules or Newton-meter
Force is measured in newtons and distance in meters
Substituting the given values,
Workdone = 20 * 5
= 100 Nm

Answer:
[tex]\angle T = 70[/tex]
Step-by-step explanation:
Given
[tex]\angle T= 2x[/tex]
[tex]\angle S= 75[/tex]
[tex]\angle R= x[/tex]
See attachment for triangle
Required
Calculate [tex]\angle T[/tex]
First, we add up the angles in the triangle;
[tex]\angle R + \angle S + \angle T = 180[/tex]
[tex]x + 75 + 2x = 180[/tex]
Collect like terms
[tex]x + 2x = 180 - 75[/tex]
[tex]3x = 105[/tex]
Solve for x
[tex]x = \frac{105}{3}[/tex]
[tex]x = 35[/tex]
Given that:
[tex]\angle T= 2x[/tex]
[tex]\angle T = 2 * 35[/tex]
[tex]\angle T = 70[/tex]

SOCCER PRACTICE BEGAN AT 2:30 P.M 3:30 P.M THROUGH WHAT FRACTION OF A CIRCLE DID THE MINUTE HAND TURN HOW MANY DEGREES DID THE MINUTE HAND TURN
Answers
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°
