Joseph was kayaking on the Hudson River. While looking at the Breakneck Ridge trail-head, he lost a whole bag of donuts. Joseph didn't realize he had lost it for fifteen minutes. That's when he turned back and started going in the opposite direction. When he found the bag, which was going at the speed of the Hudson's current, it was two miles from the Breakneck Ridge trail-head. What is the speed of the current in the Hudson River?

Answers

Answer 1

Answer:

8 miles per hour

Step-by-step explanation:

Actually pretty simple. It took 15 minutes for the bag to travel two miles from the Breakneck Ridge so it will be four miles per 30 minutes six miles per 45 minutes and 8 miles per hour.

Step-by-step explanation:

180-70=110

Answer:

∠CEF = 110°

Step-by-step explanation:

ΔBED ,

∠BED +  ∠BDE + ∠DBE = 180 {Angle sum property}

∠BED + 40 + 30 = 180

∠BED + 70 = 180

∠BED = 180 -70

∠BED = 110°

∠CEF = ∠BED     {Vertically opposite angles}

∠CEF = 110°

Maggie cut out 4 right triangles of equal size from construction paper. Each right triangle has a base of 6 inches and a height of 8 inches. What is the total area, in square inches, of all the triangles combined?

Answers

Answer:

24

Step-by-step explanation:

First you multiply 6 and 8 then you divide by 2 to get 24

The total area of all the triangles combined is 96 square inches.

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.

The area of a right triangle is found by multiplying the base by the height and dividing by 2.

Since each triangle has a base of 6 inches and a height of 8 inches, the area of each triangle is (6 x 8) / 2 = 24 square inches.

Since Maggie cut out 4 triangles of the same size, the total area of all the triangles combined is 4 x 24 = 96 square inches.

The function is proportional.
The difference between consecutive output values is a constant.
The function is exponential.

Answers

Answer:

E. (The function is exponetial)

Step-by-step explanation:

We look at the output values and subtract them from their previous value to see it's slope.

6-2 = 4

12-6 = 6

4 ≠ 6, meaning that the slope is not constant.

4 < 6, meaning that the slope is increasing, meaning the function is exponential.

A=72

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

Hello There!

The polygon shown below is a kite

We can calculate the area of a kite using this formula

[tex]A=\frac{pq}{2}[/tex]

where p and q = the diagonals

The diagonals of the shown kite are 12 ( found by adding 10 and 2) and 12 ( found by adding 6 and 6 )

So having found the diagonals we plug them into formula

[tex]A=\frac{12*12}{2} \\12*12=144\\\frac{144}{2} =72[/tex]

so we can conclude that the area of the polygon is 72
