Find t24 for the sequence 100,64,28...

serious [3.7K]

Answer:-728

Step-by-step explanation:

100,64,28,....

First term(a)=100

Common difference(d)=64-100=-36

Using the formula

Tn=a+ dx(n-1)

T24=100-36(24-1)

T24=100-36x23

T24=100-828

T24=-728

Jordan flipped a coin 492 times. Which of the following would be a good estimate of the number of times the coin landed on heads

Irina-Kira [14]

I'd say B. but that's only because I divided the number of times he flipped the coin by the number of sides it has, 2, and came up with 246. The closest number on here to that is 231 or B. I hope I helped.

Please help, will give brianlist.<br><br> 1. Solve the equation. Show all of your work.

$x + \frac{3}{7 } = \frac{5}{7}$

$\frac{7x + 3}{7} = \frac{5}{7}$

$(7x + 3) \times 7 = 5 \times 7$

by cross multiplication.

$49x + 21 = 35$

$49x = 35 - 21$

$49x = 14$

$x = \frac{14}{49}$

$x = \frac{2}{7}$

OLga [1]

To answer this question, we just need to subtract the low ( -22 ) from his much it rose ( 35 ).

$35 - 22 \\ 13$
So the highest temperature was 13.
