pls show how you got the answer 56.35 divided by 7

Answers

394.45/7=56.35. First times the awnser by what you divide it by, then thats your awnser

Answer:

Honestly It would be hard to show how I got it, but I can try. The answer is 8.05.

Step-by-step explanation:

Your supposed to see how many times 7 goes into 56.35.

1. Can 7 go into 5? No. What about 56? Yes. It goes into 56 8 times. So right now you have 8.

2. Subtract that 56 by 56 and you get 0. Now carry down 3.

3. Since 7 can't go into 3, then what about 35? Yes. 7 goes into 35 5 times. Now you should have 8.05.

Answer:

28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

A = LW = (8)(4) = 32

The area of the missing triangle is ...

A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

32 - 4 = 28 . . . square units

_____

Alternate solution

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

A = 1/2(b1 +b2)h

A = (1/2)(2 +4)(4) = 12

The area of the square is ...

A = s² = 4² = 16

Then the total area is ...

12 +16 = 28 . . . square units

Okay so the diameter is 6 inches right? And the area formula for a circle is: A=pi (they want you to use 3.14) r (radius) ^2 (squared)

A=(pi)r^2

and the area formula for a square is just sxs right? Side x side.

So 6x6=36 (that’s the area for the square)

And since we know the diameter we can figure out the are of the circle (I know it’s a half circle but just wait I’ll get to that)

Diameter is twice the radius.

So likewise the radius is half the diameter.

6/2=3

The radius is 3 inches.

So let’s plug that into the formula

A=(pi)3^2

That comes out to 113.1 inches

Since it’s half a circle we divide it by 2

That’s 56.55

So we add them.

56.55+36= 92.55 inches

The answers is 92.55

Write a function rule for “The output is 6 more than five times the input.” Use x for the independent variable and y for the dependent variable. y=

Answers

Answer:

y=5x+6

Step-by-step explanation:

+6 is six more than.

5x is five times the input.

For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.

What are X axis and Y axis?

A line that is used to take or mark measurements is known as an axis in mathematics. Two crucial axes of the coordinate plane are the x and y axes. A horizontal number line is the x-axis, while a vertical number line is the y-axis.

The coordinate plane is created by the perpendicular intersection of these two axes. The ordinate and abscissa are other names for the x-axis and y-axis, respectively.

A graph is made up of two crucial lines called the x and y axes. In a graph, data can be represented on both the horizontal and vertical axes. A graph makes it simple to understand how a point might be defined vertically or horizontally.

Therefore, It's A because point -2, and point -3 moving in those directions will never meet.
