Answer:
115
Step-by-step explanation:
The angle of a straight line is 180°. so all you have to do is subtract 65 from 180 and get 115.
Answer:
3.428 or 3 wholes 3/7
Step-by-step explanation:
6 : 7 = n : 4 : 2
6 : 7 = n : 4
6/7 = n/4
7n = 24
n = 24 /7
n = 3. 428 or 3 wholes 3/7
1/4 exact form, 0.25 decimal form.
The answer is -|0.35 t -14| +14
<u>Step-by-step explanation</u>:
The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.
The area of the trapezoid is 118 squre units
<h3>Area of a trapezoid</h3>
The formula for calculating the area of a trapezoid is expressed as:
- A = 0.5(a+b)h
- a = AD = √20
- b = BC = √80
- height = h = √40
Substitute into the formula
A = 0.5(√1600)*√40
A = 0.5 * 40 * √40
A = 20√40
A = 118 squre units
Hence the area of the trapezoid is 118 squre units
