During a day a student spends 7 hours sleeping, ¹/4 of the day studying and of the time travelling. What fraction of the day is left for other things?
Answers
Answer:
[tex]\dfrac{5}{24}[/tex]
Step-by-step explanation:
Time Spent Sleeping=7 hoursTime Spent Studying=[tex]\frac{1}{4}[/tex] of the dayTime Spent Travelling=[tex]\frac{1}{4}[/tex] of the dayThere are 24 hours in a day, therefore:
Time Spent Studying=[tex]\frac{1}{4}[/tex] X 24 =6 HoursTime Spent Travelling=[tex]\frac{1}{4}[/tex] X 24 =6 HoursThe total hour used for sleeping, studying and travelling=7+6+6=19 hours
Hours used for other things=24-19=5 hours
Therefore, the fraction of the day used for other things=[tex]\dfrac{5}{24}[/tex]
You have $12 to buy five goldfish for your new fish tank. Write and solve an inequality that represents that prices you can pay per fish.
Answers
The prices you can pay per fish can be represented by the inequality 5x ≤ 12. After solving the inequality, the maximum price you can pay per fish is $2.40.
Explanation:To write the inequality that represents the prices you can pay per fish, let's assume that the price of each goldfish is 'x' dollars. Since you have $12 in total, the inequality can be written as:
5x ≤ 12
To solve this inequality, divide both sides by 5:
x ≤ 2.4
Therefore, you can pay at most $2.40 per fish.

solve the equation 20x-5y=10 for y
Answers
20x = 5y + 10
Minus 10 to the opposite side.
20x - 10 = 5y
Divide everything by 5 to get the value of y.
4x - 2 = y
Hope that helped! :)
First of all, if you want "y" by itself, let's move "20x" to the other side. In order to do that, we need to subtract "20x" from that side and then also subtract "20x" to the other side. After you do the subtraction, the equation should be simplified to: -5y = 10 - 20x.
Then, now to get "y" by itself, you need to get rid of "-5". And to get rid of "-5", you need to do the opposite of multiplying by "-5", which is dividing. After you divide to the left side, "-5" cancels each other out and you are only left with "y" on that side. Now, you nee to divide "5x" to the right side.
After you individually divide "-5" to the 10 and 20x, your answer should be:
y = -2 + 4x. Hope this helps. =)
A computer store bought a program at a cost of 20$ and sold it at a selling price of 24$ find the percent markup
Answers
Markup percentage = price difference/original price
First, subtract the new price from the original.
$24 - $20 = $4
Second, divide the price difference by the original price.
$4/$20 = .20
Turn decimal into percentage by moving it to the right twice or multiplying by 100.
.20*100 = 20%
You can check it by multiplying the original cost by 20% then adding it to the original cost.
20*.20 = $4 , 20+4 = $24 (current price)

Any line that is perpendicular to another line has a negative reciprocal of the slope. So the negative reciprocal of -2/3 is 3/2. Now with the new slope, let's pt it in the equation to find the slop-intercept equation BY using point-slope form: y-y1 = m (slope) (x-x1).
If I put the numbers in the equation, it would look like: y+8 = 3/2 (x-4). Let's simplify by distributing 3/2 to the parenthesis: y + 8 = 3/2x - 6.
To get "y" by itself, let's subtract 8 from both sides: y = 3/2x - 14.
So, the equation is now y = 3/2x - 14.
In the box you would write, "-14".

Cody was going to sell all of his stamp collection to buy a video game. after selling half of them he changed his mind. he then bought seventeen more. how many did he start with if he now has 44?
Answers
Cody started with 54 stamps in his collection. The problem was solved using basic algebra by setting up an equation and working backwards.
Explanation:The subject of this question is mathematics, specifically dealing with a basic algebra problem that requires working backwards to find the original number of items in a collection. To solve the problem, we can set up an equation to represent the scenario given:
Let's call the original number of stamps 'x'. After selling half of them, Cody would have ½x. When he buys seventeen more stamps, the equation to represent this situation is ½x + 17 = 44. To find the value of 'x', we need to subtract 17 from both sides of the equation, which gives us ½x = 44 - 17 or ½x = 27. To find the full value of x, we multiply both sides of the equation by 2, which gives us x = 27 * 2 or x = 54.
Therefore, Cody started with 54 stamps in his collection.

Why do you subtract exponents when dividing powers with the same base
Answers
Answer:
[tex]\displaystyle\frac{x^r}{x^s} = x^{r-s}[/tex]
Step-by-step explanation:
The quotient rule of exponential power states that:
[tex]\displaystyle\frac{x^r}{x^s} = x^{r-s}[/tex]
This can be easily understood with the help of an example:[tex]\displaystyle\frac{x^4}{x^2} = \displaystyle\frac{x\times x\times x\times x}{x\times x} = x^2 = x^{4-2}[/tex]
Basically, this quotient rule helps us to reducing the fractions. Since the numerator and the denominator is same as we have same base, we could simply subtract the powers to get the answer as illustrated in the above example.
When dividing powers with the same base, subtracting exponents simplifies the expression due to the quotient of powers rule is [tex]a^m / a^n = a^{(m - n).[/tex]
When dividing powers with the same base, subtract the exponents because of the properties of exponents.
The rule is known as the "quotient of powers" rule, and it states that when you divide two powers with the same base,
subtract the exponents to simplify the expression.
The rule can be stated as follows:
[tex]a^m / a^n = a^{(m - n).[/tex]
Here's why this rule works,
Let's say you have a number 'a' raised to two exponents 'm' and 'n':
[tex]a^m[/tex]= a × a × a ×... (m times)
[tex]a^n[/tex] = a × a × a × ... (n times)
Now, to divide these two powers, cancel out the common factors:
[tex]a^m / a^n[/tex] = (a × a × a ×... ... × a) / (a × a × a ×...... × a)
In the numerator and denominator, there are 'm' and 'n' occurrences of 'a', respectively.
Since we are dividing, we can cancel out 'n' occurrences of 'a' from the numerator and denominator:
[tex]a^m / a^n[/tex] = (a × a × a ×... ... × a) / (a × a × a ×...... × a)
= [tex]a^{(m - n)[/tex]
Therefore, when divide powers with the same base, subtract the exponents to simplify the expression and apply this property of exponents.

Answers
The calculation that is NOT a relevant way to find the value of 14/20 is given by option a: 0.5 + 0.05.
Let's find the value of 14/20 first:
To find 14/20, divide 14 by 20:
14 ÷ 20 = 0.7
Now, let's check each calculation:
a. 0.5 + 0.05 = 0.55 (Not relevant to finding 14/20)
b. 0.75 - 0.05 = 0.7 (Relevant, as this gives us 14/20)
c. 14 ÷ 20 = 0.7 (Relevant, as this is the correct calculation for 14/20)
d. 14 × 0.05 = 0.7 (Relevant to finding 14/20)
Therefore, the calculation that is NOT a way to find 14/20 is option a: 0.5 + 0.05.

x^2+16x=18
Answers
x^2 + 16x = 18
x^2 + 16x (-18) = 18 -18
x^2 + 16x - 18 is your answer :D
In order to find the 'c' value to complete the square, you use the equation c = (b/2)^2. Since 16 = b, c will equal 64. 16/2 = 8, and 8^2 = 64. The final resulting equation will be (x+8)^2 = 82.
Estimate the value of 9.9 squared x 1.79
Answers
Final answer:
To estimate the value of 9.9 squared times 1.79, round 9.9 to 10, square it to get 100, and multiply by 1.79 to get an estimate of 179.
Explanation:
The question asks to estimate the value of 9.9 squared times 1.79. To estimate this value, we can round 9.9 to the nearest whole number, which is 10. Then we square 10 to get 100, and multiply this by 1.79.
So, the estimated value would be:
102 × 1.79 = 100 × 1.79 = 179
This estimation approach uses basic arithmetic principles and rounding techniques to simplify the calculation.
