Answer: the lower limit is 1.555g and the upper limit is 1.564g
Step-by-step explanation:
a mg is:
1mg = 0.001g
Then we need to look at the third digit after the decimal point.
Then the weight 1.56g is rounded around this.
Remember that if the third digit after the decimal point is 5 or bigger, then we round up.
if the third digit is smaller than 5, then we round down.
Now, the maximum possible value of this weight is when the third digit is equal to 4 (4 mg) where because it is smaller than 5, we round it down to 1.56g
Then the maximum is 1.564g
And the minimum value is when we have:
w = 1.555g
Because the third digit is a 5, we round it up to 1.56g.
So the lower limit is 1.555g and the upper limit is 1.564g
Answer:
C) 65,535
Step-by-step explanation:
You can add up the 8 terms ...
3, 12, 48, 192, 768, 3072, 12288, 49152
to find their sum is 65535.
_____
<em>Estimating</em>
Knowing the last term (49152) allows you to make the correct choice, since the sum will be more than that and less than double that.
_____
<em>Using the formula</em>
You know the formula for the sum of a geometric sequence is ...
S = a1(r^n -1)/(r -1)
where a1 is the first term (3), r is the common ratio (4), and n is the number of terms (8).
Filling in the values, you find the sum is ...
S = 3(4^8 -1)/(4-1) = 4^8 -1 = 65535
Answer:
yes, he would have enough money
He would need a total of 1.5 gallons to paint the wall .
the cost of 1.5 gallons is $18 dollars.
Andrew has 40. he has enough money
Step-by-step explanation:
total gallon needed to pain four walls = 3/8 x 4 = 1 1/2 gallons
total cost of 1 1/2 gallons = 1 1/2 x $12
to calculate this amount convert 1 1/2 to improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
3/2 x $12 = $18
