Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
They sold a total of 90 boxes
Natalie sold 1/3 of this......1/3 * 90 = 90/3 = 30....so Natalie sold 30.
that leaves (90 - 30) = 60.....Ellie sold 60
ratio of Natalie to Ellie is : 30/60 which reduces to 1/2.
so the ratio is : 1/2 or 1:2 or 1 to 2 <==
Answer:
<h2>-7</h2>
Step-by-step explanation:
The base of the prism is a 3:4:5 right triangle.
One of the legs is its base and the other is its height. (The longest side is the hypotenuse!)
The area of the triangular base is bh/2 = (9)(12) / 2. There are two of these.
There are also three rectangular sides on the prism.
Their dimensions are 9 by 20, 12 by 20, and 15 by 20.
You can do the arithmetic from here.
And the answer is 828cm ^2
