(7x10*5)x(3x10*2) in standerd form

marishachu [46]

Answer:

21,000

Step-by-step explanation:

This is more of straightforward multiplication, so I cannot explain much! If you want me to try to do more, then just comment.

(7 * 10 * 5) * (3 * 10 * 2)

= (70 * 5) * (30 * 2)

= (350) * (60)

= 21,000

Thusly, in standard form, the equation given is $\boxed{21,000}$ .

Hope this helps! (:

Substitute the given values into the formula, and solve for the unknown variable.

Alla [95]

Answer:

$h=\frac{1}{6}$

Step-by-step explanation:

Given:

$A=\frac{1}{2h} (B+b)\\$

$A=21, B=2, b=5 ,h= ?$

We have to find the value of 'h'

So, putting the given values in the equation to find the value of 'h'.

$A=\frac{1}{2h} (B+b)$

Implementing the given values in the given equations:

$21=\frac{1}{2h}(2+5)\\\\ 21=\frac{1}{2h} (7)\\\\\frac{1}{2h}=\frac{21}{7}\\\\ \frac{1}{2h}=3 \\\\h=\frac{1}{6}$

So, the value of 'h' is

$h=\frac{1}{6}$

Find the sum of the arithmetic series given ai = 45, an = 85, and n = 5.

seraphim [82]

Answer:

C. 325.

Step-by-step explanation:

The last term a5 = 85

a1 = 45

Sum of n terms = n/2 (a1 + l)

So here we have n = 5, a1 = 45 and the last term l = 85

= (5/2)(45 + 85)

= 5/2 * 130

= 325.
