Solve for t

d=(1/2) at^2

Answers

Answer 1
Answer: (1)/(2)at^2=d\ \ \ \ |multiply\ both\ sides\ by\ 2\n\nat^2=2d\ \ \ \ |divide\ both\ sides\ by\ a\n\nt^2=(2d)/(a)\ \ \ \ |square\ root\ both\ sides\n\nt=\sqrt(2d)/(a)
Answer 2
Answer: d=(1)/(2)at^2\n 2d=at^2\n t^2=(2d)/(a)\n t=\sqrt{(2d)/(a)}

x=number of 4 dollar tickets
y=number of 10 dollar tickets

total is 300 so
x+y=300

value=number of certain ticket times value of ticket
value of 4dollar ticket=x times 4=4x
value of 10dollar ticket=y times 10=10y


total value=1950
therefor
4x+10y=1950


the equations are
x+y=300
4x+10y=1950

very confusing since the options are doublepasted or something
answer is A

Can someone help me I got these three questions wrong

We know that Frank is 1/4 Dana's age, so if Frank is represented by f, and Dana is represented by d, then the equation would be 

1/4d = f

Secondly, we know that Neil's age is one-half the difference between Dana's and Frank's ages.  Because of we learned that Frank is a fraction of Dana's age, we can infer that he is younger than Dana.  So, if Neil's age is represented by the variable n, then the equation would be

1/2(d - f) = n 

Finally, if we know that Dana is 16 years old, we can find out the other siblings ages using the equations we made above.

d=16
1/4d = f
1/4(16) = f
4 =f 

1/2(d - f) = n 
1/2(16-4) = n
1/2(12) = n
6=n

Therefore, Frank is 4 years old and Neil is 6 years old.

Two students went to the schools clinic with fevers Isabell had a temperature of 103.78 and Bryan had a temperature that was 2.36 less what was Ryan’s temperature?A) 101.39
B) 106.17
C) 103.78
D) 108.57

Answers

Answer:

1)  The temperature of Bryan  is 101.39°

Step-by-step explanation:

Here, the Temperature of Isabell is given =   103.78 degrees

Now, the temperature  of Bryan = Iaabell's Tempt.  - 2.36

So, temperature  of Bryan  =   (103.78  - 2.36)  degrees

                                              =  101.4  degree

Hence, the temperature of Bryan =    101.4  degree

So, the most appropriate option is 101.39°

you should multiply 4 by 9 and then add to 1 so you gonna have : 37/9 :))
i hope this is helpful 
have a nice day 
4 1/9
= 4+ 1/9 
= 4* (9/9)+ 1/9 (because 9/9=1, it won't change the result).
= (4*9)/9 + 1/9
= 36/9+ 1/9
= 37/9

The final answer is 37/9~
