1/20=0.05. Which calculation is NOT a way to find 14/20?
a. 0.5+0.05
b. 0.75−0.05
c. 14÷20
d. 14·0.05
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.

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.

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. =)

B.

C.
perimeter of = 37

D.
perimeter of = 44
perimeter of = 66
Answers
You can then follow the same steps on the triangles you have.
Let perimeter of triangle 1 be p1 and that of triangle 2 be p2
First, we know that the ratio between p1 : p2 is 3:2, this means that:
p1/p2 = 3/2
p1 = (3/2) p2 .............> equation I
We also know that the sum of perimeters is 110, this means that:
p1 + p2 = 110 .........> equation II
Substitute by equation I in equation II as follows:
(3/2) p2 + p2 = 110
(5/2) p2 = 110
p2 = 44
Substitute by p2 in equation I to get p1 as follows:
p1 = (3/2) (44) = 66
Therefore:
perimeter of triangle 1 = p1 = 66
perimeter of triangle 2 = p2 = 44
Answer:
Perimeter of triangle 1 = p1 = 66
Perimeter of triangle 2 = p2 = 44

Add. Simplify the answer to lowest terms before entering the numerator and denominator in their boxes. 11/16 + 3/16
Answers
Answer:
The answer is 7/8.
Step-by-step explanation:
If you add 11/16 to 3/16, you'll get 14/16. 14/16 has two numbers that are divisible by 2, so when you divide 14/16 by 2 you'll get 7/8 which is 14/16 in a simplified form. 7 is prime and you can't divide it down any more, but 8 i'snt the same way. The rule is, whatever you do to one side, you have to do to the other. You can divide 8, but not 7; therefore, you cannot simplify the fraction any further.
To add fractions with the same denominator, simply add the numerators together, while keeping the denominator the same.
Explanation:To add fractions with the same denominator, simply add the numerators together, while keeping the denominator the same. In this case, we have 11/16 + 3/16. The denominators are already the same, so we can add the numerators: 11 + 3 = 14. The fraction 14/16 cannot be simplified further.

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)

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.

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.

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.
