If a calculator is sold for R120.00. What will the new price of a calculator be if the
original selling price is Increased in a ratio of 5:3
Answer:
300
Step-by-step explanation:
5/3=120/x
300
The new selling price of the calculator will be R200.00.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, If a calculator is sold for R120.00.
Now, The original selling price is increased by a ratio 5 : 3, which can also be written as 5/3.
Therefore, The new selling price of the calculator will be,
= (5/3)×12000.
= 5×4000.
= 20000.

Find the volume of the square pyramid.
Answer:
243 ft³
Step-by-step explanation:
V = [tex]\frac{1}{3}[/tex]Bh
A = 9 x 9 = 81
81 x 9 = 729
729 / 3 = 243
When you see [tex]\frac{1}{3}[/tex] in a math formula, it means to divide by 3.
For example, when you are trying to find the volume of a pyramid or cone you will see [tex]\frac{1}{3}[/tex] in the formula.
Let me know if this helps!
Answer:
729 ft³
Step-by-step explanation:
I found this answer by something I learned. All you have to do is multiply the 3 numbers of the square pyramid.
9 x 9 x 9 = 729 ft³

What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The number of students at a particular school who have the flu is increasing at a rate of 12% per day.
At the beginning of Monday there were 56 students with the flu,
Now,
Since, The number of students at a particular school who have the flu is increasing at a rate of 12% per day.
Hence, The percent of increasing rate on Friday morning = 4 x 12%
= 48%
Thus, The number of students who have the flu on Friday morning is,
⇒ 56 + 48% of 56
⇒ 56 + 48 × 56 / 100
⇒ 56 + 26.88
⇒ 82.88
Thus, The number of students who have the flu on Friday morning will be;
⇒ 83

Katie made desserts for a bake sale at her school. At the bake sale, she sold 5 brownies and 15 cookies. What percent of the desserts that Katie sold were cookies? Please help me .
Answer:
Percent of cookies to total desserts = 75%
Step-by-step explanation:
Given:
Number of brownies sold by Katie = 5 brownies
Number of cookies sold by Katie = 15 cookies
Find:
Percent of cookies to total desserts
Computation:
Number of total desserts = 5 brownies + 15 cookies
Number of total desserts = 20 desserts
Percent of cookies to total desserts = [Number of cookies sold by Katie / Number of total desserts]100
Percent of cookies to total desserts = [15 / 20]100
Percent of cookies to total desserts = [0.75]100
Percent of cookies to total desserts = 75%

Answer:
3
Step-by-step explanation:
Since we already know c, so we need to find b.

b² = 5² - 4²
b² = 25 - 16
b² = 9
b = 3
A traffic consultant wants to estimate the true proportion of cars on a certain street that have more than two occupants. She stands at the side of the road for two hours on a weekday afternoon and flips a coin each time a car approaches. If the coin comes up heads, she counts the number of occupants in the car. After two hours, she has counted 103 cars, 15 of which had more than two occupants. Which condition for constructing a confidence interval for a proportion has she failed to satisfy
Answer:
The data is a simple random sample from the population of interest.
Step-by-step explanation:
Conditions necessary to consider when constructing a confidence interval include using a large sample size, which should be greater Than or equal to 30 for n and a sample proportion of np ≤ 10. Importantly the sample must be a random sample drawn from the population, meaning that all the population of interest must have equal chances of being a part of the sample data. However, the scenariomabiveb, violates this condition as the sampling design is not completely randomized. Those who do not ply the route on that certain day have no Chaves of being part of the sample.

What would the slope of a line be that is perpendicular to the line 3x + 2y = 67
Type your answer in the box below. Use the / for the fraction bar.
What would the slope of a line be that is perpendicular to the line 3x + 2y = 6?
And why is it right
Answer:
2/3
Step-by-step explanation:
The slope of a line that is perpendicular to another line must be the negative reciprocal of the other line. This means that the slope is flipped (3/2 would be 2/3, or 5 would be 1/5) and that the sign is also changed. If the slope of the other line is positive, then the slope of this line would be negative, and vice-versa.
First, we try to get the variable y by itself, so subtract 3x from that side of the equation and then divide everything by 2. So, it would now be y= -3/2 + 3.
Then, you find the negative reciprocal of 'm', so -3/2 would be change to 2/3
