Answers

Answer:

= 10

Step-by-step explanation:

[tex]r + (s+1)^{2}[/tex] ÷ [tex]3[/tex]

if, r = 7 and s = 2

SO..

[tex]7 + (2+1)^{2}[/tex] ÷ [tex]3[/tex]

..

Add 2 and 1 to get 3.

[tex]7 + \frac{3^{2} }{3}[/tex]

Calculate 3 to the power of 2 and get 9.

[tex]7 + \frac{9}{3}[/tex]

Divide 9 by 3 to get 3.

7 + 3 = 10

answer: 10
step one: replace r with 7 and a with 2
this will bring you to the equation 7+(2+1)^2 ÷3. (if you don’t know “^2” means squared or to the power of 2)
step 2: do what’s in the parenthesis first following PEMDAS which would be (2+1) and 2+1 is 3. now your equation is 7+3^2 ÷3

step 3: do the exponent, 3^2 is 3*3 which equals 9 so the new equation is 7+9 ÷3

step 4: now you have to do division, 9 ÷3 = 3 so our new equation is 7+3

step 5: addition is last and we have to do 7+3 which is 10 so your answer is 10!


hope this was a good explanation!

Sam sold half of his comic books and then brought seven more. He now has twelve. how many did he began with?
Please show work and answer.

Answers

Answer:

He began with 10 comic books

Step-by-step explanation:

12 - 7 - 10 comic books he started out with

10 ÷ 2 = 5

5 left after he sold half of his comic books

5 + 7 = 12 comic books after he brought seven more

Hope this helps!

He began with 10 books
12-7=5
And the story problem says “he sold half” so then 5 x 2 = 10 (you got the five from dividing the 10 by 2)

SOLUTION:

by putting x = 4y - 1 in the equation x + 2y = 11, we get;

=) 4y - 1 + 2y = 11

=) 6y = 11 + 1

=) y = 12/6

=) y = 2

Now that we got the value of y we can put the value in the equation x = 4y - 1.

=) x = 4(2) - 1

=) x = 8 - 1

=) x = 7

Hence, the value of x is 7 and y is 2.

6. What is the probability of Zack drawing the letter C, keeping it, and then drawing the letter E?

7. What is the probability of Zack drawing the letter S, replacing it, and then drawing the letter U?

8. What is the probability of Zack drawing the letter that is not a vowel, keeping it, and then drawing the letter A?​

Answers

Answer:

Q5: There are 15 cards. Drawing an A first time is 3/15. Drawing A the 2nd time is 3/15 because the cards get replaced, drawing letter T is 2/15. Drawing the diagram, the answer I've got is 8/167

The other questions: Sorry I don't have enough time!

The requried probability for 5, 6, 7, and 8 have been shown below.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
From the cards,
Total cards = 15
Number of A = 4
Number of T = 2
Number of C = 2
Number of U = 1
Number of E = 3

Number of vowels cards {A, E, U} = 8

5.

The probability of  Zack drawing the letter A, replacing it, and then drawing the letter T is given as,
= probability of A * probability T
= 4/15*2/15
= 6/225

Similarly,
6. Probability of Zack drawing the letter C, keeping it, and then drawing the letter E is given as;
= 2/15*3/14
= 6/210

7. the probability of Zack drawing the letter S, replacing it, and then drawing the letter U is given as:

= 1/15*1/15
= 1/225

8. the probability of Zack drawing the letter that is not a vowel, keeping it, and then drawing the letter A is given as:
= (1 - 8/15)*4/14
= 28/210

Can someone give me a strategy please (WILL MARK AS BRAINLIEST!)

Answers

Answer:

184,900

Step-by-step explanation:

First divide.

Do a division problem, 2150 / 86.

The result is 25.

Now, setup the multiplication.

86 x 2150

How many times does 86 go into 2150? 25 times.

now we have 2150.

Use the lesser number we started with, 86, and then multiply it by the biggest number, 2150.

This would give us 184900.

I hope this strategy helps you! The strategy is to find the least common multiple of the multiplier, keep it in your head, multiply the least common multiple by the multiplier. multiply the multiplier by the first number in this case 2150, and you get the final result.

answer is 184,900!!!!!!

Q2

Answers

The answer is 3.

You divide the total by 15 then subtract 5.50 (pretty sure) which gives you 3
Option 4, $3.00

Because Bobby has 15 coins in his collection, and the value of those items amounts to $127.50 in total, divide 127.5/15, so that each coin is worth $8.50 today. Sense the value of each coin has increased by $5.50 in the last few years, all you need to do is subtract 8.5-5.5 to get your answer. In conclusion, Bobby’s coins were worth $3.00 each a few years ago.
