When x = 0, y = 1.5 * 0 = 0
Complementary angles have a sum of 90°
Supplementary angles have a sum of 180°
So
∠b=90-a=90-38=52°
∠c=180-b=180-52=128°
Answer:
29.3
Step-by-step explanation:
to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.
first we have to find the sum of the minutes she practiced:
20+30+40+38+25+22+39+22+26+31
this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:
293/10 =29.3
The correct answer, I believe is 13230, hope it helps!!
Yes 921/3 = 307 873 is not divisible by 4 and 491 is also not divisible by 3
