How do I multiply 89 x 38 by using partial products? PLEASE ANSWER FAST
olga_2 [115]

Answer:

The result after partial products of 89 x 38 is 3382

Step-by-step explanation:

We need to solve 89 x 38 using partial products.

In Partial products we divide each term such that 89 can be written as 80 and 9 while 38 can be written as 30 and 8

We will multiply each term with other and then find their sum.

Multiplication is shown in figure attached.

Now adding the results of each cell in the table:

2400+640+270+72= 3382

So, the result after partial products of 89 x 38 is 3382.

Right the slope intercept form of the equation of of each line
Burka [1]

Answer:

Slope intercept form is y=mx+b

So y=-1/2x(m=slope which you go down one over 2 from your y-intercept)

y=-1/2x ( There would be no b because your b is 0, that's where it crosses the y axis)

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?
Scrat [10]

Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.
