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.

The average petrol consumption of a vehicle is 1 gallon per 35 km. The cost of 1 litre of petrol is $49. Fund the cost of petrol for a journey of 280 km.
(take 1 gallon=4.5 litres)
Step-by-step explanation:
Total petrol consumption of the journey=
Total distance travelled ÷ Average petrol consumption
[tex] = 280 \div 35 \\ = 8 \: gallons[/tex]
Given 1 gallon = 4.5 litres,
[tex]8 \: gallons \: = 8 \times 4.5 \\ = 36 \: litres[/tex]

A bag contains 3 red marbles and 4 blue marbles. A marble is taken at random from the bag and replaced. Another marble is taken from the bag.
Work out the probability that the two marbles taken from the bag are the same colour.
Give your answer as a fraction.
Answer:
25/49
Step-by-step explanation:
probability of red and red is (3/7)(3/7) = 9/49
Probability of blue and blue is (4/7)(4/7) = 16/49
Probability of same color = prob. of red and red or prob. of blue and blue
= 9/49 + 16/49
= 25/49

Answer:
Ruffly 6.5
Step-by-step explanation:
a^2+b^2=C^2
In this case we need to find a so we do c^2-b^2.
9.8^2-7.3^2=42.75
Square root of 42.75 is ruffly 6.5
Answer:
6.5 km
Step-by-step explanation:
hypotenuse (h)=9.8km
base(b)=7.3km
perpendicular (p)=?
we know,
p^2 =h^2-b^2
p^2=(9.8)^2-(7.8)^2
p^2= 96.04-53.29
p^2=42.75
(p)^2=(6.5)^2
p=6.5km

A function has to have only one y-value for every x-value. This means that D is not a function because it contains (6,2) and (6, 4), which means that there are 2 different y-values for the x-value of 6.
The model shows 4 = 2x - 2 What value of x makes the equation true?
Answer:
You showed no model. However, looking at this equation it seems the answer would be x=3.
Step-by-step explanation:
Add 2 to both sides which leaves you with 6=2x and then divide both sides by 2 to get x=3.

The number of students at a particular school who have the flu is increasing at a rate of 12% per day. If at the beginning of monday there were 56 students with the flu, then which of the following is closest to the number of students who have the flu on friday morning?
Answer:

Step-by-step explanation:
MATH
The number of students who have the flu on Friday morning will be;
⇒ 83
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

Answer: x=22.0 (nearest tenth)
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos, Tan.
To which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin and then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos, then the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A' is for Opposite over Adjacent.
Because we have the Adjacent (angle next to 60°) and the Hypotenuse we would be using Cos.
So first you would write:
Cos 60=11/x
Then we would have to do the inverse to 'undo' the equation to get x on it's own. This would then look like:
x Cos 60=11
Then we do the inverse again:
x=11/Cos 60
so, x=22.0 (to the nearest tenth)

A line passes through the point (-2,7) and has a slope of -5
Answer:
y - 7 = -5(x + 2) a = -1Step-by-step explanation:
The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = -5
(-2, 7) ⇒ x₁ = -2, y₁ = 7
y - 7 = -5(x - (-2))
y - 7 = -5(x + 2)
(a, 2) ⇒ 2 - 7 = -5(a + 2)
-5 = -5a - 10
5a = 5 - 10
5a = -5
a = -1

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.
