The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.
Answer:
£ 537.63
Step-by-step explanation:
original price = 100%
selling price = 100% - 7% = 93% = £500
just do the proportion or ratio
[tex] \frac{100\%}{93\%} = \frac{original \: price}{500} [/tex]
OP = 500 x 100% / 93%
OP = £ 537.634
rounded to the nearest penny and become £ 537.63

In a survey of 3,400 people who owned a certain type of car, 1,700 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
50%
Step-by-step explanation:
Calculation for What percent of the people surveyed were satisfied with the car
Using this formula
Percentage of people satisfied=Owners of car/Numbers of people to buy the same car again
Let plug in the formula
Percentage of people satisfied=1,700/3,400 people*100
Percentage of people satisfied=0.5*100
Percentage of people satisfied=50%
Therefore the percentage of the people surveyed who were satisfied with the car is 50%

Answer:
The correct answer is B.)
Step-by-step explanation:
How many questions was the test? Was it 34 or 44?
The expression (x² + 3) / (x-3)(x-1) is the simplified form of the given expression. which is the correct answer would be an option (B).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given below as:
(x-3)/(x-1) + 6/(x-3)
To simplify the expression, we can first combine the terms that have a common denominator:
(x-3)²+ 6(x-1) / (x-3)(x-1)
We can simplify the expression further by using the fact that
(x² + 9 - 6x + 6x - 6) / (x-3)(x-1)
Combine the likewise terms and apply the arithmetic operation,
(x² + 3) / (x-3)(x-1)
Thus, the simplified expression is:
(x² + 3) / (x-3)(x-1)

simplify (3s^8)^-5 write your answer using only positive exponents. help please!!
Answer:
1 / ( 243s^40 )
Step-by-step explanation:
For this problem, we need to know that a negative exponent simply can be rewritten in the opposing part of the fraction, for this case, the denominator. So we can simplify as shown:
(3s^8)^-5
= 1 / (3s^8)^5
= 1 / 3^5 * s^8^5
= 1 / 243 * s^40
= 1 / ( 243s^40 )
Cheers.
The expression [tex]\left (3s^8 \right )^{-5}[/tex] is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]
Define exponent.The amount of times an integer is multiplied on its own is referred to as an exponent.
Given expression is [tex]\boldsymbol{\left (3s^8 \right )^{-5}}[/tex]
Use the formula: [tex]\boldsymbol{\left ( a^m \right )^n=a^{mn}}[/tex] to simplify the expression.
[tex]\left (3s^8 \right )^{-5}=3s^{8\times (-5)}[/tex]
[tex]=\boldsymbol{3s^{-40}}[/tex]
So, the expression is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]

Answer:
Maximum value of z = 21
Minimum value of z = -9
Step-by-step explanation:
We have to maximize/minimize the given equation for the given constraints as,
x ≥ -1
y ≤ -2x + 3
y ≥ -1
By using the graphing tool,
Corner points for the feasible region are,
A(-1, 5), B(-1, -1) and C(2, -1)
For A(-1, 5),
z = 4x + 5y = 4(-1) + 5(5)
= -4 + 25
= 21
For B(-1, -1),
z = 4(-1) + 5(-1)
= -4 - 5
= -9
For C(2, -1),
z = 4(2) + 5(-1)
= 8 - 5
= 3
Maximum value of z = 21
Minimum value of z = -9

Q.10...In a cookie mix, we find chocolate chip cookies, spice cookies, and ginger cookies in a ratio of 4 : 3 : 3. If a bag of the mix contains 33 ginger cookies, how many chocolate chip cookies are there?
Answer:
13.2
Step-by-step explanation:
Let 4x represent the chocolate chip cookies
Let 3x represent the spice cookies
Let 3x represent ginger cookies
4x + 3x + 3x = 33
10x = 33
x = 33/10
x = 3.3
Since 4x represents chocolate chip cookies
4 × 3.3
= 13.2
Hence there are 13.2 chocolate chip cookies

Answer:
40) 105 miles (mi)
42) 3.2 centimeters (cm)
Step-by-step explanation:
First determine which part of the ratio corresponds to what. Once you have figured that out, divide by the part of the ratio that corresponds to your given part and then multiply that by the other part of the ratio to derive the quantity.
If a:b
Then a × a/b = b, and b × a/b = a.
You can think of : as "to".
For example, you are given a map with a scale ratio of 1 in : 20 mi, this means that for every inch of the map, there is an actual distance of 20 miles.
So in this situation, the left part of the ratio is the length of the map in inches, and the right part of the ratio is the real distance in miles. For x inches of the map, there is 20 x miles of actual distance. Therefore 3.5 inches has an actual distance of 3.5 × 20 miles or 105 miles of actual distance.
For problem 2, you are given a ratio of 1 m : 2 cm, this means that for every 1 meter of the drawing, there is 2 cm of the plant. Therefore if you have 1.6 meter of the map, then you have 1.6 × 2 cm of the plant or 3.2 cm. For both situations the left part of the ratio is 1 which means that you just multiply by the right part of the ratio by which you are given.
