Explain how to use a tape diagram to find 90% of 180

Answers

Using a tape diagram, we find that 90% of 180 is 162.

A tape diagram, also known as a bar model, is a visual representation used to solve mathematical problems. To find 90% of 180 using a tape diagram, follow these steps:

Step 1: Draw a tape diagram with a bar that represents the whole value, which is 180 in this case.

Step 2: Divide the bar into 10 equal segments, representing 100% of the value.

Step 3: Shade 9 out of the 10 segments to represent 90% of the value.

Step 4: Determine the value represented by the shaded segments. Since 9 out of 10 segments are shaded, the value is 9/10 of 180.

Step 5: Calculate the result. 9/10 of 180 is (9/10) * 180 = 162.

Therefore, using a tape diagram, we find that 90% of 180 is 162. This visual representation helps understand the concept of percentages and provides an intuitive way to solve the problem.

You must make a tape diagram going by 10 percents. 10, 20, 30... Then, put 180 over the 90 percent. Then, do 180 divide by 10 to find out 10 percent. That is 18. Then do 18 times 9 which is 162.

Also, you could make 90 a decimal. 0.90. 0.90 times 180 is 162.

The midpoint of AB is M (2,0). If the coordinates of A are (7, -2), whatare the coordinates of B?

Answers

Answer:

The coordinates of point B are (-3,2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

$M((x_1+x_2)/(2),(y_1+y_2)/(2))$

we have

$M(2,0)\n(x_1,y_1)=(7,-2)$

substitute

$(2,0)=((7+x_2)/(2),(-2+y_2)/(2))$

Find the value of x_2

we have that

$2=(7+x2)/(2)$

$4=7+x_2\nx_2=-3$

Find the value of y_2

we have that

$0=(-2+y_2)/(2)$

$0=-2+y_2\ny_2=2$

therefore

The coordinates of point B are (-3,2)

How who u solve 5+2(x-3)

Answers

5+2(x-3)
First you do everything in the parentheses.
2 times x= 2x
2 times -3=-6
Now you have 5 + 2x- 6
5 plus -6=-1
Now you have 2x-1=0
Add the -1 to both sides.
2x-1+1=0+1
Now simplify that to get: 2x=1
Now you divide each side by 2 to get x by itself.
So, x= 1/2

To solve 5+2(x-3), you must do the following...

You must use the distributive property to get an answer.

So, 2(x-3), correct? Okay, so first you multiply 2 times x, which would give you:

2x

Then you multiply 2 times 3, which gives you 6.

So now, you have 5+2x-6 - (Basically, we just extended the problem.)

Then we just simplify, which gives you... (drumroll please...?) 2x-1.

Hope this helps!
