Answer:
<u>It is 3</u>
Step-by-step explanation:
Multiplication is one of the four basic operations in arithmetic, along with addition, subtraction, and division. Multiplication can actually be considered repeated addition, and you can solve simple multiplication problems by adding repeatedly. For larger numbers, you'll want to do long multiplication, which breaks the process down into repeated simple multiplication and addition problems. You can also try a shortcut version of long multiplication by splitting the smaller number in the problem into tens and ones, but this works best when the smaller number is between 10 and 19.
- <u>Restate the problem as an addition problem. </u>
- <u>Add the repeated number together to get your answer. </u>
- <u>Switch to long multiplication when multiplying 2-digit or larger numbers.</u>

Percent formula : is/of = %/100
is = 187.05
of = 645
% = x
now we sub
187.05/645 = x/100
this is a proportion and we now cross multiply
645(x) = (187.05)(100)
645x = 18705
x = 18705/645
x = 29
so... 187.05 is 29% of 645
u can use the percent formula on all percent problems...just make sure u sub the numbers in the right spot.
Hello!
To find the lateral area you use the equation
You put in the values you know and you get 829.4
To find the surface area you use the equation
Put in the values you know and you get 1209.5
The answer is A
Hope this helps!
Where: I= P*r*t
<span><span>
P is the principal amount, $500.00.
</span><span>r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
</span><span>t is the time involved, 4....year(s) time periods.
</span><span>So, t is 4....year time periods.
</span></span>
To find the simple interest, we multiply 500 × 0.05 × 4 to get that:
<span>The interest is: $100.00</span>
