Well knowing that 1000ml = 1L
325 ml would equal 325/1000 or 13/40 of one litre.

Answer:

\frac{325}{1000}\text{ liter}=\frac{13}{40}\text{ liter}

Step-by-step explanation:

We are asked to represent 325 ml as a fraction of a liter.

We know that one liter is equal to 1000 ml.

To represent 325 ml as a fraction of a liter, we will divide 325 by 1000 as:

315\text{ ml}=315\text{ ml}\times  \frac{\text{1 liter}}{1000\text{ ml}}=\frac{325}{1000}\text{ liter}

We can reduce our fraction as:

\frac{13\times 25}{40\times 25}\text{ liter}=\frac{13}{40}\text{ liter}

Therefore, our required expression would be \frac{325}{1000}\text{ liter}=\frac{13}{40}\text{ liter}.

If 40 percent of a movie ticket costs $5.00 what is 20 percent of the cost of two tickets
Nikolay [14]
<u>Find cost of a ticket:</u>

40% = $5.00

1% =  $5 ÷ 40 = 0.125

100% = 0.125 x 100 = $12.50

The cost of a ticket is $12.50


<u>Find 20% of two tickets:</u>

Two tickets cost $12.50 x 2 = $25

20% of $25 = 0.25 x $25 = $5

Answer: 20% of two tickets cost $5

Which facts could be applied to simplify this expression? Check all that apply.
kykrilka [37]

The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.

C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.

D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Hope this helps!

frutty [35]

The answer is: APR = 10.56%

Explanation:   Using an excel spreadsheet and the RATE function, we can calculate the monthly interest rate of buying the car:

=RATE(72,-489,25995)

= 0.8803% monthly interest rate

Then we multiply the monthly interest rate by twelve to get the APR:

APR = 0.8803% x 12 = 10.56%

If the inflation rate doubles, does the percentage decrease in buying power also double? If not, is the new percentage decrease
Nadya [2.5K]

Answer: It doubles

Step-by-step explanation:

Inflation erodes the value of a currency thereby reducing the purchasing power that customers have as they will only be able to buy less gods and services for the same amount as before.

An increase in inflation is directly proportional to a decrease in purchasing power which means that if the inflation rate doubles, the decrease in purchasing power doubles as well.

For instance, if inflation is 10%, the value of a dollar becomes 0.9c. If Inflation doubles to 20%, the dollar goes to 0.8c. Meanwhile the purchasing power would have gone from $1 to 0.8c which would translate to a 20% decrease.

In a random sample of 90 students in first grade, the mean hours of sleep per night was 9.2 with a standard deviation of 0.37 in
ss7ja [257]

Answer:

Option C is right

Step-by-step explanation:

Given are two samples

I group has sample size 90, mean = 9.2 and std dev =0,.37

II group has sample size 70, mean = 7.3 and std dev = 0.58

we find that mean difference i.e. difference between mean hours of sleep between two groups

= 9.2-7.3 = 1.9

Std error for difference = 0.0620

Since sample size is sufficiently large we can use Z critical for 99%

i.e. 2.58

Margin of error =±2.58(0.062)

=0.16

Hence confidence interval 99% for difference in hours of sleep

= (1.9-0.16,1.9+0.16)

=(1.74, 2.06)
