Maria claims that any fraction located between 1/5 and 1/7 on a number line must have a denominator of 6.
Enter a fraction that shows Maria's claim is incorrect.
Step-by-step explanation:
I want to know about exponent and surds
Explanation:
Let's rewrite each given fraction with a common denominator of 5*7 = 35.
1/5 = (1/5)*(7/7) = 7/35
1/7 = (1/7)*(5/5) = 5/35
Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.
Put another way: 5/35 < 6/35 < 7/35 since 5 < 6 < 7
This then means 1/7 < 6/35 < 1/5
Therefore, Maria's claim is incorrect.

Mr. Baxter has 250 students. Of the 250 students, 130 are girls. What is the ratio of the boys to the total number of students in Mr. Baxter's class
Answer:
It is 12boys:13girls
Step-by-step explanation:
The total is 250 out of which 130 are girls. So it is 250-130 which is 120boys. Now to find the ratio it is 120:130 which in its simplest form is 12 boys:13 girls.

Julia keeps track of her driving so that she can take a tax deduction. Julia drove 120 miles last month, in comparison to 78 miles this month. By what percent has her monthly driving decreased?_____%
Answer:
Step-by-step explanation:
The percent decrease in Julia's monthly driving would be 35.9%. This is calculated by taking the difference between the two months (120 - 78 = 42) and dividing it by the initial amount (120) and then multiplying the result by 100. (42/120)*100 = 35.9%.
Her monthly driving decreased by 35%
Step-by-step explanation:
120m - 78m = 42miles 42/120 × 100 = 35 %Anyone able to help me with this problem?

The table shows the numbers of bags of different flavors of potato
chips on a store shelf. A customer will randomly select one bag of
potato chips from the shelf.
Potato Chips
Flavor:
Plain = 12
Jalapeño = 18
Ranch = 8
Cheese = 20
Which statement about the flavor of the potato chips chosen is best
supported by the information in the table?
F) The flavor is least likely to be plain.
G) The flavor is twice as likely to be jalapeño as ranch.
H) The flavor is equally likely to be plain, jalapeño, ranch, or cheese.
J) The flavor is more than twice as likely to be cheese as it is to be ranch.
Answer:
Step-by-step explanation:
we can start with process of elimanation.
f) wrong. this is because 12 is the second smallest number out of the four with ranch being the smallest with 8.
g) wrong. this is because 8x2=16, which means its not twice as likely it would end up. being more than twice as likely.
h) wrong. all of these numbers are different, so are smaller and bigger than others, so the rate of probability is going to be different for each chip type.
j) right. this is because if we do 8x2=16, that is still smaller than 20 so it is MORE than 2x as likely since 20 is a greater number than 16.
CORRECT ANSWER: J.
hope this helped!!
The statement which best supported is J) The flavor is more than twice as likely to be cheese as it is to be ranch.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Total number of chips = 12 + 18 + 8 + 20 = 58
Probability of finding Plain chips = 12/58 = 0.2069
Probability of finding Jalapeno chips = 18/58 = 0.3103
Probability of finding Ranch chips = 8/58 = 0.1379
Probability of finding Cheese chips = 20/58 = 0.3448
The flavor is least likely to be Ranch, not plain.
Twice the probability of Ranch = 0.2759
Hence the correct option is The flavor is more than twice as likely to be cheese as it is to be ranch.

A pole that is 3.2m tall casts a shadow that is 1.14m long. At the same time, a nearby tower casts a shadow that is 39.75m long. How tall is the tower? Round your answer to the nearest meter.
Answer:
112 meters--------------------------------
The heights and shadows are proportional since they form similar triangles.
Set equal proportions and solve for the missing length:
H/h = S/s, where H and h represent heights, S and s - shadows.H/3.2 = 39.75/1.14H = 3.2*39.75/1.14H = 112 (rounded)Answer:
112 meters
Step-by-step explanation:
3.2/1.14 = x/39.75
3.2/1.14 = 2.81
2.81 * 39.75 = 111.57 = 112

When Alex bought his new car
in 2006, it was worth $28,350.
In 2015, it was worth a third
of its original value. Find the
rate of change in the value of
the car from 2006 to 2015.
A) -$1,275/yr
B) -$1,500/yr
C) -$1,650/yr
D) -$1,800/yr
E) -$2,100/yr
Answer:
A) -$1,275/yr
Step-by-step explanation:
The value of the car in 2015 was a third of its original value in 2006, which means that the value of the car decreased by 2/3.
To find the rate of change, we can use the formula:
rate of change = (final value - initial value) / (time elapsed)
In this case, the initial value is $28,350, the final value is a third of that value, which is $28,350 * (2/3) = $18,900. The time elapsed is 2015 - 2006 = 9 years.
So the rate of change is:
rate of change = ($18,900 - $28,350) / 9 = -$9,450 / 9 = -$1,050/yr
Therefore, the rate of change in the value of the car from 2006 to 2015 is -$1,050/yr.
The correct option is A) -$1,275/yr
The rate of change in the value of the car from 2006 to 2015 is -$1,800/yr, the correct option is D
What is the average rate of change?The average Rate of Change of the function f(x) can be calculated as;
[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]
f(x) represents the function x
Given;
Its worth in 2006= $28,350
In 2015 it was worth a third of its original value
Now,
Car value in 2015= 1/3 x 28,350
=9450
Number of years from 2006 to 2015
=8
Rate of change in value per year= 9450/8
=1181
Therefore, the rate of change will be -$1,800/yr
