A show is on Friday, Saturday and Sunday

Gwar [14]

Answer:

270 tickets are sold for the Sunday show.

Step-by-step explanation:

Given:

Two-fifth of the total tickets are sold for the Saturday show.

Tickets sold for the Saturday show = 240

Three times as many tickets are sold for the Sunday show as for the Friday show. This means that tickets sold for Sunday show is three times that for Friday.

Let the tickets sold for Friday show be 'x'. Therefore, tickets sold for the Sunday show is given as 3 times of 'x' = $3x$

Total tickets sold = Sum of all tickets sold on Friday, Saturday and Sunday.

Total tickets sold = $x+3x+240$

Total tickets sold = $4x+240$

Now, as per question, two-fifth of the total tickets are sold for Saturday show and ticket sold on Saturday is 240. So,

$\frac{2}{5}\times(4x+240)=240\\\\8x+480=240\times5\\\\8x=1200-480\\\\8x=720\\\\x=\frac{720}{8}=90$

Therefore, tickets sold for the Sunday show = $3x=3\times90=270$

Hence, 270 tickets are sold for the Sunday show.

Stephen evaluated (6.34 x 10^-7)(4.5 x 10^3). His work is shown below. Which statements describe his errors? Check all that appl

Lostsunrise [7]

We have the following expression:
(6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
The solution shown is:
(6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
(6.34 x 4.5) (10 ^ -7 x 10 ^ 3)
28.53 x 10 ^ -4
-28.53 x 10 ^ 4
-2.853 x 10 ^ 3
The errors are:
A. He changed the sign of the coefficient. A negative exponent does not affect the sign of a coefficient in scientific notation. The sign of the exponent determines the direction the decimal is moved in.
D. He got the wrong value for the coefficients; 28.53 x 10^-4 is not possible. The coefficients in scientific notation are always greater than 1, but less than 10.
