(yx1) + 2
y + 2
yes you’re right !
To find the surface are, we can add up the area of all of the sides.
Top:
4in x 9in = 36in^2
Bottom:
<span>4in x 9in = 36in^2
</span>
Front:
5in x 9 in = 45in^2
Back:
<span>5in x 9 in = 45in^2
</span>
Right:
4in x 5in = 20in^2
Left:
<span>4in x 5in = 20in^2
</span>
Adding them all together:
36+36+45+45+20+20 = 202in^2
The surface area of the prism is 1. 202 in^2
Answer:
15.02
Step-by-step explanation:
24-8.98
okay so pretty much all you do to make the problem easier is to make the 24 a decimal as well (24.00) than just subtract like this:
24.00
- 8.98
Than once you've set it up like that, subtract. Start in the tenths place which is 0-8. you can't do that so you borrow from the ones place. and that is also 0, so you borrow from 4. than the 4, you cross it out and it turns into a 3, the 0 beside it, cross it out and put a 9 above it because the 0 beside it is borrowing. so now it'll be
23.90
- 8.98 (pretend the far right 0 is crossed out and has a 10 over it)
than you subtract and should get: 15.02
(it sounds weird im sorry explaining over this is complicating)
Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.
