a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.
Answers
Answer:
A
Step-by-step explanation:
Ok first we need to find rate of MILES per HOUR
320/6.4=50
m= miles in 9 hours
9*50=450
Cross Multiplyis your answer
A
(6.4*9)/320m=Hours/miles
Hope this helps!
The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.
We know that speed is the ratio of distance and time. Then we have
The number of miles the bus will travel in 9 hours will be
320 / 6.4 = m / 9
6.4 / 320 = 9 / m
Then the correct option is B.

Answers
Answer:
I would need to know the number of radios she made each day.
Step-by-step explanation:
lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***
you would get $6.48
then for sunday we would do 0.62 x 2 (that would be 1.24) .
now we add 6.48 and 1.24 to get $7.72 a week.

A restaurant owner has found that 80% of her customers return to the restaurant within two weeks.

Which spinner simulation uses an appropriate device and has the correct number of trials? a spinner divided into 5 congruent sectors, spun 3 times a spinner divided into 5 congruent sectors, spun 4 times a spinner divided into 2 congruent sectors, spun 3 times a spinner divided into 2 congruent sectors, spun 4 times
Answers
B. A spinner divided into 5 congruent sectors, spun 4 times
Have a good day
The correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks.
The correct spinner to use among the 4 should have a probability of winning of 80%, similar to what the owner has found out. So, we must calculate the probability of each spinner.
1. Spun 3 times, and chance of winning is 1 in 5, therefore P = (3) (1/5) = 0.6 = 60%
2. Spun 4 times, and chance of winning is 1 in 5, therefore P = (4) (1/5) = 0.8 = 80%
3. Spun 3 times, and chance of winning is 1 in 2, therefore P = (3) (1/2) = 1.5 = 150%
4. Spun 4 times, and chance of winning is 1 in 2, therefore P = (4) (1/2) = 2 = 200%
We can see that there is only 1 choice that has 80% probability,
Hence, the correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”

Explain how to tell if two terms are alike. Show one pair of like terms that each contain at least two variables. Show how to add these like terms. Then show a second pair of terms that are NOT alike, but share some of the same variables. Explain why they are not alike.
Answers
Answer:
Two mathematical terms are alike (not alike) , if they have same (different) variables & in same (different) mathematical treatment.
Step-by-step explanation:
Two mathematical terms are alike, if they have same variables & in same mathematical treatment.
Eg : 2 xy , 5 xy. These are alike, as they have product of x & y being multiplied with constants.
They can be added, subtracted by adding or subtracting their constants.
2 xy + 5 xy = (2 + 5) xy = 7 xy
5 xy - 2 xy = ( 5- 2 ) xy = 3 xy
Two mathematical terms that are not alike are : 2 xy & 5xz , as former has variables x & y, latter has variables x & zIf nuts cost $9.20 per pound, how much would 2 1/2 pound cost?

O 8, 12, 16
O 3,4, 5
O 9, 10,
Answers
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
3.) There are 3 brothers. The first brother is twice as old as the second. The second is twice as old as the third.
If the sum of their ages is 28, how old is each brother?
Answers
Answer:
The first brother is 16, the second brother is 8 and the third brother is 4.
Step-by-step explanation:
Since the sum of all the brothers is 28, that means the cap of how old the oldest can be is 28. I just stated with numbers less then 28 that were dividable by two which means all the numbers had to be. So 16 for the first, 8 for the second and 4 for the youngest is the right answer I hop.

The absolute value of −6 is less than the absolute value of 6.
−6 is closer to zero on the number line than −7 , so |−6|<|−7| .
Answers
Answer:
The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)
Step-by-step explanation:
Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).
