There are 3 more English teachers than math teachers at strey Junior Hight. If the ratio of english teacher is 6:5 how many math teachers are there. I think I know but want to double check :)

Answers

Answer 1

Answer: let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3

ratio if e to m is 6:5

e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18

Whích strand of mRNA would be made during transcription using the DNAstrand shown below?
AGC GCT
O A. UCG CGU
O B. TCG CGA
O C. UCG CGA
O D. AGC GCT

Answers

In both DNA and RNA, pairs are formed between cytosine and guanine. In DNA, adenine pairs with thymine, but in RNA it pairs with uracil.

So the corresponding mRNA strand would be

HELP PLZA biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. What are their speeds?

Answers

The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

What is speed?

Speed is the distance that a particle or body travels in one hour. It has a scalar value. It is the time-to-distance ratio.

We know that the speed formula

Speed = Distance/Time

A biker’s speed is 1.5 times faster than a walker’s speed.

Let y be the speed of the biker and x be the speed of the walker. Then the equation is given as,

y = 1.5x

They begin going simultaneously from the same location in the same direction, and after 1.5 hours, there are 12.5 miles separating them.

y - x = 12.5 / 1.5

1.5x - x = 25/3

0.5x = 25/3

x = 16.67 miles per hour

Then the speed of the biker will be given as,

y = 1.5 (16.67)

y = 25 miles per hour

The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.

Step-by-Step explanation:

Leave the speed of a walker alone x

Let the speed of a biker be 1.5x

They are moving a similar way,

thus, their Relative speed will be

1.5x - x =0.5x

Time taken = 1.5 hours

Separation between them = 12.5 miles

As we probably am aware the equation for "Distance":

*Picture attached*

Consequently, the Speed of the walker be 16.67 miles every hour

Speed of biker be

1.5 times 16.67=25 miles per houe
