a 14 ounce energy drink contains 10 1/2 teaspoons of sugar. How much sugar is in one ounce of the drink?

Answers

Answer:

(3)/(4) sugar is in one ounce of the drink.

Step-by-step explanation:

Unit rate is defined as the rate are expressed as a quantity as 1 such as 3 meter per second or 4 miles per hour.

As per the statement:

A 14 ounce energy drink contains 10 1/2 =(21)/(2) teaspoons of sugar.

We have to find how much sugar is in one ounce of the drink.

By unit rate definition we have;

\text{Unit rate per ounce} = ((21)/(2))/(14) = (21)/(2 \cdot 14)

⇒\text{Unit rate per ounce} = (21)/(28) = (3)/(4)

Therefore, (3)/(4) sugar is in one ounce of the drink

$1,200, 3.9%, 8months

Answers

Answer:

$1231

Step-by-step explanation:

Given,

Principal amount = $1200

Rate of interest = 3.9%

Time = 8 months or (8/12) 0.666667 years

Formula of simple interest = A=P(1+rt)

A=1200(1+(3.9* 0.666667)/(100))

A = 1200(1+(0.039 × 0.666667))

A = 1200 (1+0.026)

A = 1200 (1.026)

A = $1231
1,200(1.039)^.66666
1200(1.02583386437)
$1231.00

31000 rounded to the nearest ten thousand

Answers

The 3 is in the ten thousands place so the number to the right of that tells you if you need to tound up or down. Anynumber 5 or higher then you round up. If lower than five you leave it alone.
So answer is slready rounded -
A number rounded to the nearest 10000, means that the last four digits of that number (on the left of the decimal point) are 0.  
However, if the fourth-last digit to the left of the decimal point is 5 or greater, the number to the left of that is rounded to 1 number higher.  For example, if you were rounding 145293 to the nearest 10000, it would be 150000. 

However, the fourth-last digit to the left of the decimal point in this case is 1.  
Therefore,  31000 rounded to the nearest 10000 is 30000.
