The answer would be 1 over 10 (A) because when you multiply two fractions, you multiply the top and bottom so in this case, 1 x 1 is 1 and 2 x 5 is 10 which gives you the answer A.

The area of a rectangle is 42 square inches. the length is 7 inches.what is the perimeter of the rectangle?

andrew11 [14]

In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.

A certain ferry moves up and down a river between Town A and B. It takes the ferry two hours to travel to Town A and only an hou

Y_Kistochka [10]

Answer:

The distance between two cities is 60 miles.

Step-by-step explanation:

Time taken to travel from B to A = 2 hours

Time taken to travel from A to B = 1.5 hours

Current speed = 5 mph

Let the speed of ferry in still water = u mph

When the ferry moves with the current, it will taken lesser time (i.e. A to B) and when it moves against the current it will take more time (i.e. B to A).

Let the distance between the two cities A and B = D miles

While moving with the current, speed = $(u+5)\ mph$

While moving against the current, speed = $(u-5)\ mph$

Formula for Distance = Speed $\times$ Time

Distance traveled in each case is same i.e. D.

So,

$D = (u+5) \times 1.5 = (u-5) \times 2\\\Rightarrow 1.5u+7.5=2u-10\\\Rightarrow 0.5u =17.5\\\Rightarrow u = \dfrac{175}{5}\\\Rightarrow u = 35 \ mph$

Now,

$D = (u+5) \times 1.5\\\Rightarrow D =(35+5) \times 1.5\\\Rightarrow D =(40) \times 1.5\\\Rightarrow \bold{D =60\ miles}$

So, the distance between two cities is 60 miles.

Given a * b=ba−ba+ab, find (2*3)×(3*2).

Vladimir79 [104]

Answer:

Step-by-step explanation:

a = (2×3) = 6

b = (3×2) = 6

Substitue into the equation:

a×b=ba−ba+ab

= 6×6 - 6×6 + 6×6

= 36 - 36 + 36

= 36

Therefore, (2*3)×(3*2) = 36

Hope this helps.☺

PLEASE IF YOU ARE SMART HELP ME WITH THIS PROBLEM. I WILL GIVE YOU EXTRA POINTS

$a_{n} = 2a_{n-1} + 3$

$a_{1} = 2$

$a_{2} = 2a_{2-1} + 3 = 2a_{1} + 3 = (2*2) + 3 = 4 + 3 = 7$

$a_{3} = 2a_{3-1} + 3 = 2a_{2} + 3 = (2*7) + 3 = 14 + 3 = 17$

$a_{4} = 2a_{4-1} + 3 = 2a_{3} + 3 = (2*17) + 3 = 34 + 3 = 37$

$a_{5} = 2a_{5-1} + 3 = 2a_{4} + 3 = (2*37) + 3 = 74 + 3 = 77$

Hence, the first five terms are 2, 7, 17, 37, 77.
