Answer:
175
Step-by-step explanation:
7(13+12)
distribute 7 to 13 and 12
(91+84)
175
By distributive property the expression 7(13 + 12) can be rewritten as 175.
To rewrite the expression 7(13 + 12) using the distributive property, we multiply 7 by each term inside the parentheses:
7(13 + 12) = 7 × 13 + 7 × 12
This simplifies to:
91 + 84
Adding the two terms, we get:
175
Therefore, using the distributive property, 7(13 + 12) can be rewritten as 175.

caroline is making some table decorations.
each decoration is made from a candle and a holder.
caroline buys some candles and some holders each in packs.
There are 30 candles in a pack of candles.
There are 18 holders in a pack of holders.
How many packs of candles and how many packs of holders does caroline buy?
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

Identify the multiplication property used in the equation 7x2=2x7
The multiplication property used in the equation 7x2=2x7 is the Commutative Property of Multiplication, stating that the order of numbers doesn't affect the product.
Explanation:The multiplication property used in the equation 7x2=2x7 is known as the Commutative Property of Multiplication. This property states that the order in which you multiply numbers does not change the product. For example, in your equation 7x2=2x7, the position of the numbers 7 and 2 have been switched, but the product remains the same (14).

What was the biggest decrease in time from the 1st leg to the 2nd leg??
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.

What is the simplified fractional equivalent of the terminating decimal 0.78
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:

A poll reported that 66% of adults were satisfied with the job the major airlines were doing. Suppose 20 adults are selected at random and the number who are satisfied is recorded.
The probability that exactly 12 are satisfied with the airlines is
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)).
Explanation: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:
C(n, k) is the number of combinations of n items taken k at a time.p is the probability of success (66% or 0.66 in this case).n is the number of trials (20 adults).k is the number of successes we're interested in (12 adults being satisfied).By subbing in these values, we can calculate the desired outcome.

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. How many hours has Carlos practiced piano? How much longer does he need to practice before going to bed in order to meet his goal?
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:

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

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

Jorge said that 0.029 can be written as 29/100. Is he correct ??
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.
Explanation: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.
