So the first thing to do is to simplify both sides of this equation:
<span>12.46x+4.5</span>=162
Next we shall subtract 4.5 from both sides so:
<span>12.46x+4.5−4.5</span>=<span>162−4.5</span>12.46x=<span>157.5
</span>Now that we are done with all those steps now here is the final steps so now we shall divide both sides by 12.46:
<span><span><span>12.46x/</span>12.46 </span>= <span>157.5/<span><span>12.46
</span>Ok so your final answer shall be:
</span></span></span>x=<span>12.640449
</span>I hope this helps you greatly!
Answer:
1.95 x 10^5
Step-by-step explanation:
First look at the 4th digit in the number 194720 as the the question said to round to 3 significant figures. If the 4th digit is more than 5, then add 1 to the third digit which results in 195000. Now the question also said to express in standard form. Look for the first non-digit number in 195000. After 1 put a decimal point and remove all the zeros after the point which results in 1.95. Now count how many digits you moved to the left which comes as 5. Write the answer as 1.95 x 10^5.
Hope you can understand this!!
$3.15 would be the cost, after the mark up is added.
No they do not have the same number of zeroes
Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600
both have 3 zeroes before multiplying
if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer
if we take 40 x 500 - 4 x 5 = 20
then theres an extra zero added
but if we take 40 x 600 - 4 x 6 = 24
no extra zeroes added to this
so if we finally look at the answers
40 x 500 = 20 000
40 x 600 = 24 000
20000 has 4 zeroes and 24000 has 3 zeroes
so the answer is no they dont have the same number of zeroes
Answer 1 = I believe you are correct cause when doing area , remembering you times the different area of the sides
Answer 2 = I believe the answer is C (2,0009) cause remember adding when doing volume but there are few steps ..
. i have done the work for this and hoping my work helped the answer i got help you! comment below if you need anything , thanks , have a nice day!!
