Marcus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked of the original price, but it was really off the original price.
He misread the advertisement.
If the original price of the game was $48, what is the difference between the price that Marcus thought he should pay and the price that the store charged him?
Answer:
$14
Step-by-step explanation:
Since the original price of the game was $48 and the store wanted to sell it with 1/4 off the total price, we can say that (48) - (48 *1/4) = 36. Since marcus thought that he was buying the game for 1/4 of the original price, that would be 48 * 1/4 = 12.
The difference between 36 and 12 is 14, which would be the answer.
A farmer raised a watermelon that weighed 20 Lb. From his experience with raising watermelons, he estimated that 95% of the watermelon's weight in water. Question: In pound's how much water of the watermelon is water.
Answer:
19
Step-by-step explanation:
5%= 1
95%=19
The water is 95% of the total weight of watermelon. Multiply 95% by the total weight to get the weight of the water.
water = 95% × 20
water = 0.95 × 20
water = 19
The weight of the water is 19 lbs

Answer:
945000
Step-by-step explanation:
do you mean adding..? if so thats your answer
The answer is 0.945 million or 945000
What is AdditionAddition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.
The addition of two whole numbers results in the total amount or sum of those values combined.
1 million = 10 lakhs = 1000000
0.6 million = 600000
On addition of 0.6 million and 345000 we get

Kyle is raising money for his school. He has $75 saved and needs to raise at least $150. He wrote part of an inequality to help him find the minimum amount of money needed to raise. Which inequality symbol can be used in the box to make this inequality correct?
≥
Answer: >_
Step-by-step explanation:
The symbol for inequality is represented as "≥".
Given data:
To find the minimum amount of money Kyle needs to raise, the inequality is determined as:
Kyle already has $75 saved, and he needs to raise at least $150.
Let's represent the minimum amount he needs to raise with the variable "x."
The inequality can be written as:
$75 + x ≥ $150
In this inequality, we are adding the amount Kyle has saved ($75) to the amount he needs to raise (x), and it should be greater than or equal to $150.
To indicate that the left side of the inequality should be greater than or equal to the right side, we use the symbol "≥" in the box.
Hence, the correct inequality symbol to make the inequality accurate is "≥".

Pedro’s car odometer measures the distance driven in kilometers. Pedro determines that, for every 810 kilometer he drives, he drives the equivalent distance of 510 mile. What is that ratio as a unit rate of kilometers to miles?
Answer:
The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.
Step-by-step explanation:
Given;
distance measured by odometer in kilometer, = 810 km
distance measured by odometer in miles, = 510 miles
The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is calculated as;
[tex]d = \frac{810 \ km}{510 \ miles} \\\\d = \frac{810 \ km \ \times \ \frac{1}{810 \ km} }{510 \ miles \ \times \frac{1}{810 \ km} } \\\\d = \frac{1 \ km}{\frac{510}{810} \ miles } \\\\d = \frac{1 \ km}{\frac{17}{27} \ miles} \\\\d = 1 \ km : \frac{17}{27} \ miles\\\\d = 1 \ km : 0.63 \ miles[/tex]
Therefore, the ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.

What specific measure of a geometric figure is shown in the image?
Answer:C, A 70 angle
Step-by-step explanation:
Answer:
The specific measure of a geometric figure is shown in the image is a 70° angle.
Thus, option 'A' is correct.
Step-by-step explanation:
We know that protectors normally have:
two sets of numbers going in opposite directions.From the figure, it is clear that:
The center point of the protector lies on the vertex of the angle.The zero mark is the bottom edge of the protractor.It is clear that the other ray tends to cross the protractor at the measure 70 degrees.
Therefore, the specific measure of a geometric figure is shown in the image is a 70° angle.
Thus, option 'A' is correct.

At first, you have 15 bottles of coke, and you drink 2 bottles each day. After a certain number of days, there are 3 bottles left. Write and solve an equation for, d, when there are 3 bottles left?
Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2
[tex]\frac{2d}{2}=\frac{12}{2}\\d=6[/tex]
Hence,
After 6 days, 3 bottles will be left.

Answer:
The rate of change of Function A is less than the rate of change of function B.
Other than that, everything else you put is correct.
Step-by-step explanation:
None.
Answer:
Option A, B and D are correct options.
Step-by-step explanation:
First we will find rate of change of function A and function B
Rate of Change of Function A
The formula used to calculate rate of change is: [tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=1, y_1=5, x_2=2, y_2=7
Putting values in formula and finding rate of change
[tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:Change=\frac{7-5}{2-1}\\Rate\:of\:Change=\frac{2}{1}\\Rate\:of\:Change=2[/tex]
So, Rate of change of Function A = 2
Now, finding y-intercept.
y-intercept is found by putting x =0
Looking at the function, we can write the equation: y=2x+3
Now, put x =0
y=2(0)+3
y=3
So, when x =0, y=3
So, y-intercept is 3 for function A.
Rate of Change of Function A
The formula used to calculate rate of change is: [tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=1, y_1=1, x_2=2, y_2=4
Putting values in formula and finding rate of change
[tex]Rate\:of\:Change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:Change=\frac{4-1}{2-1}\\Rate\:of\:Change=\frac{3}{1}\\Rate\:of\:Change=3[/tex]
So, Rate of change of Function B = 3
Now, finding y-intercept.
y-intercept is found by putting x =0
Looking at the graph, when x=0, y is -2
So, y-intercept is -2 for function B.
We get following answers:
Rate of change of Function A = 2
Rate of change of Function B = 3
y-intercept is 3 for function A.
y-intercept is -2 for function B.
So, The correct options are:
The rate of change of function A and B are positive
The rate of change of function A is less than the rate of change of function B. (Because 2 is less than 3)
The y-intercept of function A is positive, while y-intercept of function B is negative.
So, Option A, B and D are correct options.
A warehouse contains ten printing machines, four of which are defective. A company selects five of the machines at random, thinking all are in working condition. The company repairs the defective ones at a cost of $20 each. In what interval would you expect the repair costs on these five machines in dollars to lie 75% of the time
Answer:
Step-by-step explanation:
There from ypergemetric distribution
mean number of defective in sample =n×m/N =5×4/10=2
and std deviation =sqrt(mn/N*(1-m/N)*(N-n)/(N-1))
=sqrt(5*4/10*(1-4/10)*(10-5)/(10-1))=0.816
from Tchebysheff's theorem ; 75% values fall within 2 standard deviation from mean
therefore interval in terms of defective
=2-2*0.816 ; 2+2*0.816 =0.367 ; 3.633
interval in terms of repair costs =20*0.367 ; 20*3.633 =$7.34 ; $ 72.66
