Answer:

Hey mate....

Step-by-step explanation:

This is ur answer....

Solution :

1) first convert them into improper fraction :

1 3/8 = 11/8

3 1/4 = 13/4

2) Find LCM of the denominators :

8, 4 = 8

3) Multiply to make the denominators same....

11/8 x 1/1 = 11/8

13/4 x 2/2 = 26/8

4) Add them up!

Hope it helps you!

Answer:

$\frac{37}{8}$

Step-by-step explanation:

1 $\frac{3}{8}$ ---------> $\frac{11}{8}$

3 $\frac{1}{4}$ ---------> $\frac{13}{4}$ (multiply by $\frac{2}{2}$ ) -----------> $\frac{26}{8}$

$\frac{11}{8} +\frac{26}{8} =\frac{37}{8}$

It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23

Should the quotient of an integer divided by a nonzero integer always be a rational number? Why or Why not?

lubasha [3.4K]

Yes, it will always be a rational number. I'll expound on this by defining what a rational number is. It is any number that can be expressed as a fraction. Otherwise, it is called an irrational number with a non-terminating decimal expansion. So, although 1/3 has a non-terminating decimal expansion because it is equal to 0.33333333...., it is still a rational number because it can be expressed into a fraction.

After 3.5 hours pasha had traveled to 17 miles if she travels at a constant speed how far will she have traveled after four hour

laiz [17]

Since we want to know how far she goes every hour to multiply that by 4 to get how far she goes in 4 hours, we do 17/3.5 to get per hour miles = around 4.86. Multiply that by 4 to get around 19.43 miles

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter aft

Makovka662 [10]

Answer:

P(X ≥ 1) = 0.50

Step-by-step explanation:

Given that:

The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.

Then; the probability of success = 7/34 = 0.20588

Using Binomial distribution to determine the probability; we have:

$P(X = x) = ^nC_x \ \beta^x \ (1 - \beta)^{n-x}$

where;

x = 0,1,2,...n and 0 < β < 1

and x represents the number of successes.

However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:

P(X ≥ 1) = 1 - P(X< 1)

P(X ≥ 1) = 1 - P(X =0)

$P(X \ge 1) = 1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg]$

$P(X \ge 1) = 1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg]$

P(X ≥ 1) = 1 - 0.50

P(X ≥ 1) = 0.50

Lincoln has set up a lemonade stand outside his house and sells small cups and large cups of lemonade. Each small cup holds 6 ou

max2010maxim [7]

Answer: The system of equations that could be used to determine the number of small cups sold and the number of large cups sold is

6x + 18y = 780

y = 4x

Step-by-step explanation:

Let x represent the number of small cups that were sold.

Let y represent the number of large cups that were sold.

Each small cup holds 6 ounces of lemonade and each large cup hold 18 ounces of lemonade. Lincoln used 780 ounces. This is expressed as

6x + 18y = 780- - - - - - - - - - 1

Lincoln sold 4 times as many large cups as small cups. This is expressed as

y = 4x
