Answer:
You get 0.95
Step-by-step explanation:
Change each percentage to decimals.
70% is equal to 0.70
25% is equal to .25
15% is equal to .15
Add the decimal of pizza to the decimal of salad.
For perimeter you will add each side together so
8ft+22ft+12ft+16ft=58
So your perimeter is 58ft.
For area your going to divide the shape into 2 to get the area as this is an irregular shape, so
Base 1+base2x height / by 2
22+8 x4/2
30x4/2
120/2
60
If you’re wondering how I got 4 I subtracted 16 with 12 to know what the height was. Good luck!!
Answer:
1.079 seconds
Step-by-step explanation:
You want to find t when H(t) = 15.
15 = -16t^2 +8t +25
10/16 = t^2 -1/2t . . . . . . subtract 24, divide by -16
10/16 + 1/16 = t^2 -1/2t +(1/4)^2 . . . . . add (1/4)^2 to complete the square
11/16 = (t -1/4)^2
t -1/4 = √(11/16) . . . . . take the positive square root
t = 1/4 +(√11)/4 = (1+√11)/4 . . . . use a common denominator
You would be 15 ft above the water at t = (1+√11)/4 ≈ 1.079 seconds.
Answer:
x = 17deg
Step-by-step explanation:
Let angle y be the unknown angle IN THE TRIANGLE.
Angle y = 180 - 90 - 73
= 17deg
Angle x = Angle y (Alternate angles on 2 parallel lines)
Angle x = 17 deg
