What is 2.1 times 3.2 find the missing partial products HELP.​
vredina [299]

Given:

The area model for 2.1\times 3.2.

To find:

The value of 2.1\times 3.2 and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

2\times 3=6

2\times 0.2=0.4

0.1\times 3=0.3

0.1\times 0.2=0.02

The complete area model is shown below.

After adding all areas of the area model, we get

6+0.4+0.3+0.02=6.72

Therefore, the value of 2.1\times 3.2 is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

The center of a circle is located at (3, 8), and the circle has a radius that is 5 units long. What is the general form of the e
babymother [125]
The answer is A. To understand that, you need to put it in order by the x's and the y's to get x^2-6x + y^2-16y = -48. Now complete the square on both the x and the y terms to get (x^2-6x+9) +(y^2-16y+64) = -48+9+64. Rewriting that in vertex form on the left and doing the math on the right gives you
(x-3)^2 + (y-8)^2 = 25, which shows you a center of (3,8) and a radius of 5.

(e) 0.892\div0.008

Step-by-step explanation:

Given

892\div8

Required

Select equivalent expression

8920\div80

894\div10

89.2\div0.08

8.92\div0.8

0.892\div0.008

Start  by solving the given expression (using a calculator)

892\div8 = 111.5

Then we solve the given options (using a calculator)

(a) 8920\div80

8920\div80 = 111.5

(b) 894\div10

894\div10 = 89.4

(c) 89.2\div0.08

89.2\div0.08 = 1115

(d) 8.92\div0.8

8.92\div0.8 = 11.15

(e) 0.892\div0.008

0.892\div0.008 = 111.5

The equivalent expressions are (a) and (e)
