Answer:

Carlos has practiced piano for [tex]\frac{29}{20}=1\frac{9}{20}[/tex] hours.

Carlos needs to practice [tex]\frac{11}{20}[/tex] hours.

Step-by-step explanation:

We have been given that Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.

First of all, we will find piano practiced before school and after school by adding both amounts as:

[tex]\frac{3}{4}+\frac{7}{10}[/tex]

Make a common denominator:

[tex]\frac{3*5}{4*5}+\frac{7*2}{10*2}[/tex]

[tex]\frac{15}{20}+\frac{14}{20}[/tex]

Add numerators:

[tex]\frac{15+14}{20}[/tex]

[tex]\frac{29}{20}[/tex]  

Therefore, Carlos has practiced piano for [tex]\frac{29}{20}[/tex] hours.

Now, we will subtract [tex]\frac{29}{20}[/tex] from 2 find number of hours Carlos needs to practice to reach his goal.

[tex]2-\frac{29}{20}[/tex]

[tex]\frac{2*20}{20}-\frac{29}{20}[/tex]

[tex]\frac{40}{20}-\frac{29}{20}[/tex]

[tex]\frac{40-29}{20}[/tex]

[tex]\frac{11}{20}[/tex]

Therefore, Carlos needs to practice [tex]\frac{11}{20}[/tex] hours before going to bed in order to meet his goal.

Answer:

there are 8 candles

Step-by-step explanation:

(i) In order to obtain an equal amount of candle to candle holders Caroline has to buy enough packs to obtain a 1:1 ratio.  

Therefore to obtain a 1:1 ratio:

=30 candles/18 candle holders * (18/30)

Therefore she needs to buy 18 packs of candles and 30 packs of candle holders to have exactly the same number of candles and holders

(ii) Caroline can make = 30*18 = 540 table decorations

Answer:

x > 7/3

Step-by-step explanation:

5(3x - 2) > 3(4x - 1)

First, use the distributive property on both sides.

15x - 10 > 12x - 3

Subtract 12x from both sides.

15x - 12x - 10 > 12x - 12x - 3

3x - 10 > -3

Add 10 to both sides.

3x - 10 + 10 > - 3 + 10

3x > 7

Divide both sides by 3.

3x/3 > 7/3

x > 7/3

Step-by-step explanation:

you can divide every number by 1

if a number is even you can always divide it by 2

if the number ends in an odd number that isn't 5, you will most likely be able to divide it by 1, 3, or 9

if a number can be divided by 3, it can most likely be divisible by 6 if its an even number

if it ends in 5, you will be able to divide it by 5

if the number is over 10 and ends in a 0 it will be divisible by 10 and/or 5

Answer:

39/50.

Step-by-step explanation:

0.78 = 78/100

= 39/50.

Answer:

39/50

Step-by-step explanation:

The original expression can be restated as follows:

0.78 = 0.70 + 0.08

Convert:

0.70 = 7/10

0.08 = 8/100

Add 7/10 + 8/100:

7/10 + 8/100

Find least common multiple, which is 100:

=(70+8)/100

=78/100

Now, simplify by dividing by 2 for both top and bottom:

The problem involves calculating a binomial probability for 12 out of 20 adults being satisfied with airlines, given a satisfaction rate of 66%. This uses the formula for Binomial Probability: P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k)).

The question involves using Binomial Probability in statistics. Here, the experiment is repeated 20 times (20 adults are selected), each trial is independent (one adult's answer doesn't affect another's), there are two possible outcomes (satisfied or unsatisfied), and the probability of success (being satisfied) is constant (66%).

To calculate the probability of exactly 12 adults being satisfied, we use the formula for Binomial Probability:

P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k))

Where:

By subbing in these values, we can calculate the desired outcome.

Answer:

The first one. 55.3 and 40. 38

Step-by-step explanation:

Subtract all of the second legs from the first legs that they go with and find the biggest number. When this is done, the first one has the biggest number.

Answer:

The biggest decrease in time is 14.92 seconds.

Step-by-step explanation:

Consider the provided table.

Consider the row 1.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.3 seconds - 40.38 seconds = 14.92 seconds

Hence, the decrease in time is 14.92 seconds

Consider the row 2.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.29 seconds - 40.402 seconds = 14.888 seconds

Hence, the decrease in time is 14.888 seconds

Consider the row 3.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.295 seconds - 40.4 seconds = 14.895 seconds

Hence, the decrease in time is 14.895 seconds

Consider the row 4.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.037 seconds - 41.2 seconds = 13.837 seconds

Hence, the decrease in time is 13.837 seconds

From the above calculation it is clear that the biggest decrease in time is 14.92 seconds.

Answer:3 5/12

Step-by-step explanation:

So we have here 1/2, 2/3 and 2 1/4. So let's ignore the 2 from 2 1/4. so we add them all up (1/2 + 2/3 + 1/4) but before we add them up we have to find the common denominator. So the common denominator for 2, 3 and 4 is 12. so the question will be 6/12 + 8/12 + 3/12. Add this up and it will be 17/12 = 1 5/12. Now let's get that 2 back here and add 2 to 1 5/12 (2 + 1 5/12) = 3 5/12

The solution to the number division 54 divided by 7 is: 7⁵/₇

Division is defined as a mathematical operation, that is written using the symbol ÷ , and the it can  be thought of in two ways: x÷y is the size of each group when x objects are divided into y groups of equal size, OR x÷y is the number of groups when a objects are divided into groups of b objects each.

We are given the expression 54 divided by 7

Thus, the number of times 54 can divide 9 in whole numbers in 7 times with a remainder of 5. Thus:

Jorge's statement is partially correct. 0.029 can be written as a fraction but it is 29/1000, not 29/100 since it has three decimal places.

Jorge's statement that 0.029 can be written as 29/1000 is indeed correct. When you convert a decimal to a fraction, we count the number of decimal places, which determines the denominator of the fraction. In the case of 0.029, it has three decimal places, therefore, the denominator would be 1000 (the first place represents tenths, the second represents hundredths and third represents thousandths). Hence 0.029 as a fraction is written as 29/1000, not 29/100.
