25 inches and 2 inches:  No
20 inches and 5 inches:  Yes
17 inches and 8 inches:  Yes
15 inches and 5 inches:  No
15 inches and 10 inches:  Yes

The first rectangle would have a perimeter of 25(2)+2(2) = 54 inches.
The second rectangle would have a perimeter of 20(2)+5(2)=50 inches.
The third rectangle would have a perimeter of 17(2)+8(2)=50 inches.
The fourth rectangle would have a perimeter of 15(2)+5(2)=40 inches.
The fifth rectangle would have a perimeter of 15(2)+10(2)=50 inches.

In a triangle the measurements of the angles are x°, ( x + 6)°, (2x + 10)°, and the sum of the three angles of a triangle is 180
34kurt

Answer:

largest angle = 92°

Step-by-step explanation:

Since the measurement of the angles are;

x°, ( x + 6)°, (2x + 10)°

And we know that sum of angles in a triangle is 180. Thus;

x + (x + 6) + (2x + 10) = 180

x + x + 6 + 2x + 10 = 180

4x + 16 = 180

4x = 180 - 16

4x = 164

x = 164/4

x = 41°

The other two angles will be;

(41 + 6)° and (2(41) + 10)°

Which gives;

47° and 92°

So,largest angle = 92°

HELP PLEASE!!! SHOW WORK!! A professional pianist spends an average of 45 hours practicing the piano in a three-week period. Usi
kicyunya [14]

Answer:

An average of about 450 hours; You could say something along the lines of "If the pianist who practices an average of 45 hours per week practices everyday for three months, they would play for approximately 450 hours total."

Step-by-step explanation:

We could write an equation to make it simpler to figure out, making the number of hours after three months = n, 4 = weeks in a month, 3 = the number of months, and 45 = the number of hours after a week. As an equation, it would look like:

45 * 3 * 4 = n

We know 3 *4 is 12, so the equation becomes 45 * 12 = n.

45 * 12 = 540, therefore the pianist practices an average of approximately 540 hours over a three-month period of time.
