Kris:
4.37 hours per day for 3 days.
To find the total practice time, multiply the practice time per day by the number of days.
4.37 • 3 = 13.11
This means Kris practiced for 13.11 hours.

Amelia:
6.39 hours per day for 4 days.
To find the total practice time, multiply the practice time per day by the number of days.
6.39 • 4 = 25.56
This means Amelia practiced for 25.56 hours.

To find the difference, just subtract Kris's practice time from Amelia's practice time.
25.56 - 13.11 = 12.45

This means Amelia practiced for 12.45 more hours than Kris.

If a aquare has a,pwrimeter of (2×-48) meters, what expression represents its area?​
qaws [65]

Answer:

A =  [ \frac{x - 24}{2} ]^{2} m²

Step-by-step explanation:

Given that a square has a perimeter of (2x - 48),

Each side of the perimeter must be: \frac{2x - 48}{4}  (because a square has 4 sides)

We need to determine the side of each perimeter:

s = \frac{2x - 48}{4}

Factor out 2 from the numerator:

s = \frac{2(x - 24)}{4}

Then, cancel out 2 and 4 from the fraction, leaving 2 in the denominator:

s = \frac{(x - 24)}{2}  ← <em><u>This represents the side of a square</u></em>

Therefore, the area of a square is:

A = side (s)²

A =  [ \frac{x - 24}{2} ]^{2} m²

Find the surface area of the prism.
Tju [1.3M]

Answer:

920 ft^2

Step-by-step explanation:

area of triangles: base x height / 2 (2)

8 x 15 / 2

= 60 x 2

= 120

area of rectangular base: length x width

15 x 20 = 300

area of sloped rectangle: length x width

17 x 20 = 340

area of rectangle: length x width

8 x 20 = 160

Total: 120 + 300 + 340 + 160

=920 ft^2
