You have a right triangle situation here, and what you are looking for is the length of the hypotenuse. The leg perpendicular to the ground is 100, and the base angle that is NOT the right angle, is 65. So your equation is set up like this: sin 65 = 100/x. Rearrange that a bit to get x alone: x = 100/ sin 65. Make sure your calculator is in degree mode and solve for x. x = 110.34 feet of string.
Answer:
-5/4
Step-by-step explanation:
slope = rise/run
Start at the lower right point. Go up 5. The rise = 5. Go left 4. The run -4.
slope = 5/-4 = -5/4
Answer: True
Step-by-step explanation: 64x8x10=51200 while 640x8x10=51200
Answer: Length = 15 inches
Width = 12 inches
Step-by-step explanation:
The painting is rectangular.
Let L represent the length of the painting.
Let W represent the width of the painting.
Area of a rectangle = LW
Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that
LW = 180- - - - - - - - - - -1
The length of the painting is 1 and 1 fourth times the width. It means that
L = 1.25W
Substituting L = 1.25W into equation 1, it becomes
W(1.25W) = 180
1.25W² = 180
W² = 180/1.25
W² = 144
W = √144
W = 12 inches
L = 1.25W = 1.25 × 12
L = 15 inches
Well you estimate the equation. 7 x 3289 to 7 x 3000 and you do 7 x 3 but add 3 zeros in the end so you get 21000
