2 3/4 divided by 1/4
is
2 3/4 multiplied by 4/1
which is (2+3/4)*4 = 2*4 + 3/4*4 = 8+3 =<em>11</em>
Answer:
12 and 1/4
Step-by-step explanation:
Answer:
Step-by-step explanation:
- Let the speed of the boat be x
- Speed against the current in the river is x - 2
<u>Time in the river:</u>
<u>Time in the lake:</u>
<u>The difference:</u>
Solve for x to find the speed of the boat
<u>Multiply both sides by x(x - 2) to clear the fraction:</u>
- 6x = 15(x - 2) - x(x - 2)
- 6x = 15x - 30 - x² + 2x
- x² - 11x + 30 = 0
- (x - 5)(x - 6) =0
- x -5 = 0, x - 6 = 0
- x = 5 km/h, x = 6 km/h
Answer:520; 240
Step-by-step explanation:
a. 13, 26, 39, 52,......
a = First term = 13
d = common difference = 26 - 13 = 13
40th term = a + (n - 1)d = a + (40-1)d = a + 39d
= 13 + (39 × 13)
= 13 + 507
= 520
b. 6, 12, 18, 24,.......
a = First term = 6
d = common difference = 12 - 6 = 6
40th term = a + 39d
= 6 + 39(6)
= 6 + 234.
= 240
The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
Step-by-step explanation:
Given,
Perimeter of hockey rink = 570 feet
Width of hockey rink = w
Length of hockey rink = w+115
As a hockey rink is in rectangular shape;
Perimeter of rink = 2(Length + Width)
Dividing both sides by 4
Width of hockey rink = 85 feet
Length of hockey rink = 85+115 = 200 feet
The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
