Answer: 87 feet
Step-by-step explanation:
The angle between the pilling is 60°
The adjacent side of the right angle is 150
So let the distance between the pilling be y, that is opposite side.
Opposite / adjacent = tan (60°)
y / 150 = tan (60)
y × tan (60°) = 150
Divide both side by tan (60°)
y = 150 / tan (60°)
y = 150 / 1.7321
y = 87 feet
Answer:
The new price is 11.99
Step-by-step explanation:
First find the mark down
14.99 * 20 %
14.99 * .20
2.998
3.00
Subtract the markdown from the price
14.99-3.00
11.99
The new price is 11.99
Answer: 3 and 3/8 or 27/8
Step-by-step explanation:
First step, you will need to move the decimal to the side by 1 place value.
0.8 --> 8. and 2.7--> 27.
Then just do your normal dividing.
27/8 = 3 and 3/8
The answer to 2.7÷0.8 can be either a mixed number or an improper fraction.
17) The line that is John is closer to certain but not exactly on certain so I'd say it's "likely"
18) Using that same example as the one above, if 0 means impossible, then 1 means certain. I'd place your label for Sara at 1.
19) Let s = sides of the square. There are 4 sides and all sides are equal so we can set up the equation 4s = 64. Divide both sides by 4. s = 16. Now add 2 to this. 16 + 2 = 18. The length of each side of the original square was 18.
20) If the scale is 1 cm : 1 meter and the height of the model is 16 cm, then the actual plane must be 16 meters.
21) 2x and 100 are supplementary angles meaning together they must add up to 180.
2x + 100 = 180
2x = 180 - 100
2x = 80
Divide both sides by 2
x = 40
22) Assuming 3x is supposed to be the right angle, right angles are 90 degrees.
3x = 90
Divide by 3 on both sides
x = 30.
