There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?

Answers

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

there are 5 non blue socks

Answer:

[tex]\textsf{b.} \quad (2x+5)^2[/tex]

Step-by-step explanation:

Given quadratic equation:

[tex]4x^2+20x+25[/tex]

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex].

[tex]\implies ac=4 \times 25=100[/tex]

[tex]\implies b=20[/tex]

Factors of 100 that sum to 20: 10 and 10

Rewrite [tex]b[/tex] as the sum of these two numbers:

[tex]\implies 4x^2+10x+10x+25[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies 2x(2x+5)+5(2x+5)[/tex]

Factor out the common term (2x + 5):

[tex]\implies (2x+5)(2x+5)[/tex]

Simplify:

[tex]\implies (2x+5)^2[/tex]

Answer:

d. 3x + 6 = 26

Step-by-step explanation:

Definitions

Integer: a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ...Even number: an integer that is exactly divisible by two. For example, 2, 4, 6, 8 are all positive even numbers.Consecutive: following one after the other in order.

The sum of three consecutive even integers

Let x be the first even integer.

As there is a difference of 2 between consecutive even integers, the next even integer after x will be (x + 2).

Therefore, the next even integer after (x + 2) will be (x + 2) + 2 = (x + 4).

So "the sum of three consecutive even integers is twenty-six" is:

x + (x + 2) + (x + 4) = 26

To solve

⇒ x + (x + 2) + (x + 4) = 26

⇒ x + x + 2 + x + 4 = 26

⇒ 3x + 6 = 26

(Please note that there are no three consecutive even integers that sum to 26, so the problem cannot be solved).

the answer to the question is d.

Step 2 blank

A:4(x2 + 2x + 1) + 15 − 4 = 0

B: 4(x2 + 2x + 1) + 15 − 1 = 0

c: 4(x2 + 2x + 2) + 15 − 2 = 0

D: 4(x2 + 2x + 4) + 15 − 4 = 0

you are going to paint the sixth sector spinner shown.There are 4 colors to choose from. How many different ways can u paint this spinner if each color can be used more than once and there are no other restrictions

Answers

Answer:

There are 4096 options to choose from.

Step-by-step explanation:

6 sections each with 4 colours to choose from : 4⁶ = 4096

The spinner with 6 different parts and 4 different colors can be painted in 4⁶ ways.

What are permutation and combination?

A permutation is an arrangement of things where order matters, AB and BA are two different permutations.

The combination is a selection of things where order does not matter, AB and BA are the same combinations.

Given, you are going to paint the sixth sector spinner shown and there are 4 colors to choose from also each color can be used more than once and there are no other restrictions.

∴ The first part can e painted in 4 different ways and as there are no restrictions every 6 parts can be painted in 4 different ways.

So, the total no. of ways to color this spinner with 6 different parts and 4 different colors are,

4×4×4×4×4×4 ways,

= 4⁶ ways.

Find the quotient. 5 1/4 - 15

a. 7/20
b. 78 3/4
c. 2 6/7
d. 3 1/4

Answers

What I find helps me with division is turning fractions into decimals. In this case 5 1/4 becomes 5.25 and 5.25/15 is .35 (equivalent to 7/20) Answer A: 7/20

The answer should be C- 2 6/7

I believe the question you are asking is what 5 1/4 (otherwise known as 5.25) divided into 15 is.

Simply put, your question is 15 divided by 5.25 (or 5 1/4)

To solve this we can make the fraction 5 1/4 into an improper fraction. This makes the fraction to consist of a numerator and a denominator and no whole numbers. Converting 5 wholes into fourths would mean 5 times 4 which is 20. Therefore 5 converted into 1/4 ‘s is 20 1/4’s. This combined with the other 1/4 in the fraction 5 1/4 makes the improper fraction 21/4.

When you divide fractions you switch the numerator and denominator of the fraction on one side (usually the right side although it doesn’t matter as long as you only switch one fraction of the two) and multiply. 15 times now 4/21 is 60/21.

To simplify this you can divide the numerator and denominator by a common factor. We can start with 3, simplifying the fraction to 20/7. Now as you may notice in the answer choices they are all mixed numbers, consisting of a whole number as well as the numerator and denominator. 20/7 as a mixed number is 2 6/7 as you can have 2 times 7 (14) and then have 6 left so you have 2 wholes and 6/7 away from another whole. This makes C the answer

The measure of angle 5 is 68° because this problem is under the category of “parallels cut by a transversal.” Under these circumstances, angles 1 and 5 are corresponding to each other. Corresponding angles are congruent, which means that they have the same measurements. This would mean that angles 1 and 5 both equal 68°.

3 friends shared 48 pineapples equally among themselves. One of the friends sold all his pineapple each at $5 how much did he get from selling the pineapples?

Answers

Answer: $80

Step-by-step explanation:

Step 1: Find how much each person got

48 pineapples shared amongst 3 people

48÷3= 16 pineapples each

Step 2: Find how much he earned

16 pineapples for $5 each

Total money made: 16x5= 80

$80 in all selling his share of the pineapples

hope this helps!!

The total amount of money the friend made from selling his pineapples is $80

How much did he get from selling the pineapples?

Total pineapples = 48

Total friends = 3

Number of pineapples each friend takes = Total pineapples / Total friends

= 48/3

= 16 pineapples per friend

Cost of each pineapple = $5

Total amount the friend made from selling his pineapples = Cost of each pineapple × Number of pineapples each friend takes

= $5 × 16

=$80

Hence, the friend made $80 from selling his pineapples.
