Mr. Howard and Ms. Egan enjoy running on the weekends. They both usually run at a steady pace and try to meet in the middle. They are 14 miles apart. Mr. Howard can run 3 miles in 30 minutes. Ms. Egan can run 4 miles in 30 minutes.
Answers
Given :
Distance between them, D = 14 miles .
Mr. Howard can run 3 miles in 30 minutes.
Ms. Egan can run 4 miles in 30 minutes.
To Find :
Time taken by them to meet.
Solution :
Mr Howard speed, [tex]v_H=\dfrac{3}{0.5}=6\ mph[/tex] .
Mr Egan speed, [tex]v_e=\dfrac{4}{0.5}=- 8\ mph[/tex] . [ Since they run in opposite direction ]
Their relative speed :
[tex]v=v_E-v_H\\\\v = 8-(-6) \ mph \\\\v = 14 \ mph[/tex]
Time taken by them to meet :
[tex]T = \dfrac{14}{14}\ hours\\\\T = 1 \ hours[/tex]
Hence, this is the required solution.

Step-by-step explanation:
plz mark brainlyest
The probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of Braxton brushing both times = (0.72×0.85) = 0.612
The Probability of Arabella brushing both times = (0.82×0.79) = 0.6478
Hence, the probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.

The heights of the apple trees in an orchard are normally distributed with a mean of 12.5 feet and a standard
deviation of 1.2 feet. What percentage of the apple trees are between 10.1 and 13.7 feet tall?
Answers
Answer:
18.141%
Step-by-step explanation:
We start by calculating the z-scores
Mathematically;
z-score = (x-mean)/SD
for 10.1
z = (10.1-12.5)/1.2 = -2
for 13.7
z = (13.7-12.5)/1.2 = 1.2/1.2 = 1
So we need the probability within this range
P(-2 < x < 1)
We can check the probability using the standard normal distribution table
That will be;
P(-2 < x < 1) = 0.18141
Converting this to percentage, we have 18.141%

Ms. Zerngast’s favorite candy is a snickers bar. It costs 7.80$ for 6 large snickers candy bars. She likes to buy them at our local center market. How many candy bars can Ms. Zerngast buy for 18.20$.
Answers
If 7.80 buys 6 chocolates then 15.60 should buy 12 with a remainder of 2.60
7.80 divided by 6 is 1.30 and 1.30 +1.30 = 2.60 so 12 +12 = 14

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 444 teams are wearing orange shirts, and 2 teams are wearing white shirts
Answers
Answer:
red
Step-by-step explanation:
The complete question is as follows;
At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts
Solution;
The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams
Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams
So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts

NO
Step-by-step explanation:
X^2+4X+3=(X+2)(X+2)
X^2+4X+3=X^2+2X+2X+4
X^2+4X+3=X^2+4X+4
Answer:
undefined
Step-by-step explanation:
x²+4x+3 = (x+2)²
first of all you open the bracket on the Right hand side..
(x+2)² = (x+2)(x+2)
= x(x+2)+ 2(x+2)
=x²+2x+ 2x+4
= x²+4x+4
therefore,
x²+4x+3 = x²+4x+4
next, we collect all like terms together,
x²-x²+4x-4x = 4-3
0+0 = 1
the answer is undefined
because 0 cannot be equal to 1
