Steven wants to buy a $565 bicycle. Steven has no money saved, but will be able to deposit $30 into a savings account when he receives his paycheck each Friday. However, before Steven can buy the bike, he must give his sister $65 that he owes her. For how many weeks will Steven need to deposit money into his savings account before he can pay back his sister and buy the bike?

Answers

30w = 565 + 65
30w = 630
w = 630/30
w = 21 weeks <=== he's got a while to go
Ok First $565 just for a bike? lol. But anyway he gets $30 each Friday but he has to pay his sister $65 first so if you just add $65 to $565 you'll get the total amount he needs which is $630 then divide that by the $30 he gets each week and you'll get 21 weeks

Alex spend 3/4 of his money. He gave 1/4 of the remainder to his sister. He had $120 left. How much did have in the beginning?

Answers

x = amount of money he had in the beginning

Because he spent 3/7, he has 4/7 left.

(4/7x)

We have to take 1/4 off THIS value. He has 3/4 of this value left.

(4/7x)1/4

Now, lets set it up as an equation

(4/7x)1/4 = 120

Multiply both sides by 4

4/7x = 480

Multiply both sides by 7/4

x = 480 * 7/4
x = 840

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.

The given expression is,

7/3 + 3(2/3 − 1/3)²

Solving the bracket,

= 7/3 + 3{(2− 1)/3}²

solving the fraction,

= 7/3 + 3(1/3)²

solving the square,

= 7/3 + 3(1/9)

= 7/3 + 1/3

60 + 84
the sum of the numbers as a product of their GCF is?

Answers

Final answer:

The sum of 60 and 84 expressed as a product of their Greatest Common Factor is 144. You determine this by first finding the GCF, which is 12, and then adding the other factors (5 and 7) together and multiplying by the GCF.

Explanation:

To find the sum of the numbers 60 and 84 as a product of their Greatest Common Factor (GCF), you first need to calculate the GCF of the two numbers. The GCF of 60 and 84 is 12. You can divide each number by 12 to find the other factors, which are 5 for 60 and 7 for 84. Therefore, the sum of the numbers can be expressed as the product of their GCF and the sum of these other factors:

60 + 84 = (12 × 5) + (12 × 7)

GCF × (sum of other factors) = 12 × (5 + 7)

Now you can add the other factors:

5 + 7 = 12

Then multiply by the GCF:

12 × 12 = 144

So, the sum of the numbers expressed as a product of their GCF is 144.

How do you rewrite 0.912912 using bar notation

Answers

You would put .912 and put a line all the way over 9 1 and 2
Final answer:

The number 0.912912 can be written in bar notation as 0.912, with a bar over 912 to indicate the repeating decimals. This method is commonly used in mathematics to represent repeating decimals.

Explanation:

To rewrite the number 0.912912 using bar notation, consider the part of the decimal that repeats. In this case, the repeating section is 912. Therefore, the number can be written as 0.912 where the 912 has a bar over it to represent the fact that it repeats. Bar notation is a way in mathematics to represent repeating decimals. The bar, or vinculum, shows which numbers repeat in the decimal. For this number, 0.912 with a bar over 912 is the way it would be written in bar notation.

what is the difference between bisectors and perpendicular bisectors?

Answers

With a perpendicular bisector, the bisector always crosses the line segment at right angles.

Final answer:

A bisector cuts a line segment or angle into two equal parts, while a perpendicular bisector not only does that but also intersects the line segment at a right angle.

Explanation:

In mathematics, a bisector is a line segment or line that divides an angle or segment into two equal parts. It cuts the angle or segment into two congruent angles or segments. For example, if you have a line segment AB and its bisector is a line segment CD, then CD divides AB into two congruent segments AC and CB.

A perpendicular bisector is a type of bisector that not only divides a line segment into two equal parts, but it also intersects the line segment at a right angle (90 degrees). So, in addition to being equidistant from the two endpoints of the line segment, the perpendicular bisector is perpendicular to the line segment as well.

Like: -8p + 5 - 5
= -3 - 5
This gives us: -8p = -8
Now we have divide by the -8 on each of your sides:
Like: -8p ÷ -8
= -8 ÷ -8
Answer: p = 1

Given : The greatest common factor of a number n and 6 is 3.

Then, it is clear that n should be a multiple of 3.

Prime factorization of 6 :

[tex]6=2\times3[/tex]

So for n a even number then the greatest common factor will be 6.

Thus , the possible choice for n is a odd multiple of 3.

Hence, the possible whole-number values for n are :

Maryann is testing the effectiveness of a new acne medication. There are 100 people with acne in the study. Fifty-five patients received the acne medication, and 45 other patients did not receive treatment. Thirty of the patients who received the medication reported clearer skin at the end of the study. Twenty-two of the patients who did not receive medication reported clearer skin at the end of the study. What is the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin?

Answers

Answer: 58 %

Step-by-step explanation:

Let M represents the event of taking medicine, M' represents the event of not taking medicine and C represents the event of clearing skin,

Thus, according to the question,

n(M) = 55,

n(M') = 45,

n(M∩C) = 30,

n(M'∩C)= 22,

⇒ n(C) = n(M∩C) + n(M'∩C) = 30 + 22 = 52

Let S shows the total number of people,

n(S) = 100

Hence, the probability of cleared skin,

[tex]P(C)=\frac{n(C)}{n(S)}=\frac{52}{100}=0.52[/tex]

And, the probability of cleared skin of that people who took the medicines,

[tex]P(M\cap C)=\frac{n(M\cap C)}{n(S)}=\frac{30}{100}=0.3[/tex]

Thus, the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin,

[tex]P(\frac{M}{C})=\frac{P(M\cap C)}{n(C)}=\frac{0.3}{0.52}=0.57692307692\approx 0.58 = 58\%[/tex]

Answer: 0.58

Step-by-step explanation:

Let A = Event that the patients received the acne medication.

B = Event that the patients did not receive the acne medication.

C = Patient reported  reported clearer skin.

Now,

[tex]P(A)=\dfrac{55}{100}=0.55\ \ ,P(B)=\dfrac{45}{100}=0.45[/tex]

[tex]P(C|A)=\dfrac{30}{55}\ \ , P(C|B)=\dfrac{22}{45}[/tex]

Using Bayes theorem, The probability that a patient chosen at random from this study took the medication, given that they reported clearer skin:

[tex]P(A|C)=\dfrac{P(A)\cdot P(C|A)}{P(A)\cdot P(C|A)+P(B)\cdot P(C|B)}\\\\=\dfrac{0.55\cdot\dfrac{30}{55}}{0.55\cdot\dfrac{30}{55}+0.45\cdot\dfrac{22}{45}}=0.576923076923\approx0.58[/tex]

Hence, the required probability : 0.58
