Answer:

well the three goes inside the division box and the 4 goes in the outside. Then you see how many times 4 goes into 3 which is 0 then you add a zero next to the three and a decimal point in between the 3 and 0. next, you see how many times 4 goes into 30 which is 7 then you subtract 30-28 which is 2 then you add another 0 and see how many times 4 goes into 20 which is 5 times then you get your answer .75

A person gets on a Ferris wheel at the starting point. The starting point is 15 feet off the ground. The Ferris wheel has a radi

lisov135 [29]

<h2>Answer:</h2>

$\boxed{\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}$

<h2>Explanation:</h2>

The height of the rider from the ground after the Ferris wheel equals the starting point is 15 feet off the ground plus the radius of the Ferris wheel plus the opposite side of the triangle ΔABC (See figure below). Hence our goal is to find this side. We have the angle $11\pi /2=165^{\circ}$ , therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

$\overline{BC}=\overline{AB}sin(75^{\circ})=50sin(75^{\circ})=\frac{25}{2}(\sqrt{6}+\sqrt{2})$

Finally, the height is:

$H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+15+50 \\ \\ \boxed{H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}$

Write a doubles fact you can use to find the sum of 6+7

Drupady [299]

We could use 7+7=14 to find the sum of 6+7.

Explanation: 
7+7=14 is one of the two closest doubles to 6+7.
We know that:
7 is 1 more than 6; this means:
7+7 will be 1 more than 6+7.
7+7=14, so finding 1 less,
6+7=13.
