X + (X+1) + (X+2) = 170 this is setting the first number equal to X, so it makes sense that X+1 is the number above it, and X+2 is 2 numbers above it.
3X + 3 = 170 now solve for X
3X =167
X = 55 2/3 now you need to add 1 and 2 to that answer to get the next 2 numbers.
So 55 2/3, 56 2/3, 57 2/3
It appears as though there are no 3 consecutive natural numbers that when added together are equal to 170.
Answer:
c. 59.3 ft²
Step-by-step explanation:
½× [(3.14×5²) + (10×4)]
= ½ × (78.5+40)
= ½× 118.5
= 59.3

Answer:
4.36
Step-by-step explanation:
14z-3-6-52 (Add all the numbers with the negative sign together)
= 14z-61 (Equation equals 0)
0 = 14z - 61 (Add 61 to zero)
0+61 = 14z ( Note :- the negative sign before 61 changes to +ve upon moving to the left hand side)
61 = 14z (Divide both sides by 14)
61/14 = 14/14
4.357 = z
z = 4.36
Answer:
Step-by-step explanation:
Let the coordinates of point B are (x, y).
Since the rotation is clockwise the angle measure between OA and OB is -60° (IV quadrant).
- x = 15 cos (-60°) = 7.5
- y = 15 sin (-60°) = -12.99
<u>The distance between A and B is:</u>
- AB = = 15 units
<h3><u>Another solution</u></h3>
Since OA = OB = 15 units and AOB is 60° angle the triangle OAB is equilateral. Hence AB is same as OA and OB, so AB = 15 units.
