D. 280 minutes
*please help, I’ll give you brainliest :)
Answer:
b or a
Step-by-step explanation:
If bus A arrives after 14 minutes and bus B arrives after 20 minutes, then both buses will arrive at 140 minutes.
Given:
Bus A = 14 minutesBus B = 20 minutesHow to find the Least common multiple(LCM)Find the least common multiple of 14 minutes and 20 minutes
14 minutes = 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 210, 224, 238, 252, 266, 280....
20 minutes = 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220.....
Therefore, the least common multiple of 14 minutes and 20 minutes is 140 minutes.

Choose... greater or less
depth than 3 m below sea level.
Okay I got the answer, so -28 is (LESS) than -3, and 28m below sea level is a (GREATER) depth than 3m below sea level! i took the test and I got it right.
Step-by-step explanation:
Complete statement is as follows -
−28 is less than −3, but 28 m below sea level is greater depth than 3 m below sea level.
What is inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given is Becky who went scuba diving. She writes an inequality statement that compares the magnitude of two depths that she reached.
We have the following expression -
|- 28| > |- 3|
The absolute value of the expression, will be -
28 > 3
Now, 28 is greater than 3.
But is we compare -28 and -3, then -28 is less than -3.
Now, if we compare the depth of 28 m and 3 m below the sea level, then 28 m represent more depth as compared to 3 m.
Therefore, we can write the complete statement as -
−28 is less than −3, but 28 m below sea level is greater depth than 3 m below sea level.

Choose the answer that BEST describes the situation. * 1 point A. The shirt will have the lowest price with the $20 off coupon. B. The shirt will have the lowest price with the 20% off coupon. C. The shirt will cost the same with either coupon. D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Step-by-step explanation:
Given two different coupon options :
First: 20% off
Second = $20 off
To our hase with one which enables one to pay the amount of money :
The price of the shirt will determine which of the coupons will give the least amount. For instance, a shirts which which cost below $100 will require the $20 off coupon in other to attain the least payment amount. However for shirts which cost above $100, the 20% coupon yield the least amount. Shirts which cost $100. Both coupons yields the same discount amount.

(3) An estate was to be divided among five people. The first person received 1/8 of the estate. The next two people each received 1/5 of the estate. The fourth person received 1/10 of the estate. What fractional part of the estate did the last person receive?
Answer:
3/8
Step-by-step explanation:
An estate has to be divided among the 5 persons.
Given that the 1st person received 1/8 of the estate,
the 2nd person received 1/5 of the estate,
the 3rd person received 1/5 of the estate,
and the 4th person received 1/10 of the estate.
Let the 5th person received the x part of the estate.
The sum of all the fractional parts of one estate equals to 1, so
[tex]\frac 1 8+\frac 1 5+\frac 1 5+\frac 1 {10}+x=1[/tex]
[tex]\Rightarrow \frac 5 8 +x =1[/tex]
[tex]\Rightarrow x =1-\frac 5 8 =\frac 3 8.[/tex]
Hence, the last person received 3/8 of the estate.
A fish was swimming LaTeX: 2\frac{1}{2}2 1 2 feet below the water's surface at 1:00 p.M. Three hours later, the fish was at a depth that is LaTeX: 3\frac{1}{4}3 1 4feet below where it was at 1: 00 p.M. What rational number represents the position of the fish with respect to the water's surface at 4:00 p.M.?
Answer:
[tex]\frac{23}{4}[/tex] feet
Step-by-step explanation:
The depth of the fish to the surface of water at 1:00 pm = 2 [tex]\frac{1}{2}[/tex] feet
= [tex]\frac{5}{2}[/tex] feet
The depth of the fish to its initial position at 4:00 pm = 3 [tex]\frac{1}{4}[/tex] feet
= [tex]\frac{13}{4}[/tex] feet
The position of the fish with respect to the water's surface at 4:00 pm = the depth of the fish to the surface of water at 1:00 pm + the depth of the fish to its initial position at 4:00 pm
= [tex]\frac{5}{2}[/tex] + [tex]\frac{13}{4}[/tex]
= [tex]\frac{10 + 13}{4}[/tex]
= [tex]\frac{23}{4}[/tex]
The position of the fish with respect to the water's surface at 4:00 pm is [tex]\frac{23}{4}[/tex] feet.
Ms. Howard wrote a test. Part A had true/false questions, each worth points. Part B had multiple choice questions, each worth points. She made the number of points for Part A equal the number of points for Part B. It was the least number of points for which this was possible.

Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and

Price reduced
25% off
Now £14 625
Work out the price of the car before it was reduced.
Step-by-step explanation:
let x be the original.price
so x * 75/100= 14625
x=19500
so the price of car before it was reduced was 19500
The price of the car before it was reduced is £19500.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that the price of the car with 25% price reduced is £14625.
Now to find the price of the car before it was reduced,
for that we will find the price of car to 100 - 25 = 75 percentage.
Let P be the price of the car before it was reduced.
P × 75 / 100 = 14625
P = 14625 × 100 / 75
P = £19500
Therefore, the price of the car before it was reduced is £19500.
