\dfrac{2}{9} \text { of the saving} = \$72

-----------------------------------------------
Find 1/9 :
-----------------------------------------------
\dfrac{1}{9} \text { of the saving} = \$72 \div 2

\dfrac{1}{9} \text { of the saving} = \$36

-----------------------------------------------
Find 9/9 :
-----------------------------------------------
\dfrac{9}{9} \text { of the saving} = \$36 \times 9

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.

Answer:

x = 16

Step-by-step explanation:

The figure shown shows an inscribed angle F and central angle E. Both angles intercept the same arc.

Therefore, angle E is twice the measure of angle F, according to the central angle theorem of a circle.

Thus,

m<E = 2 * m<F

(x + 94)° = 2(55)

We can find the value of x with this equation.

x + 94 = 110

Subtract 94 from both sides

x = 110 - 94

x = 16
