93.50/8.50 = 11
She can by 11 tiles.
Answer:
44.8
Step-by-step explanation:
cos α = adjacent leg/hypotenuse
cos 48° = 30/x
x = 30/(cos 48°) = 44.8
Answer:
Step-by-step explanation:
In 1 hour,Jamal covers =4 electrical outlets
If he works at the same pace for 7.5hours,he would cover 7.5×4=30 electrical outlets.
Y=3(x²+10x)+71
Now we need to complete square for (x²+10)
It should look like this
a²+2ab+b²=(a+b)²
y=3(x²+2*5x+5²)-3*5²+71
y=3(x+5)²-75+71
y=3(x+5)²-4
Vertex has coordinates x=-5, y=-4.
Vertex in this case is the extreme value (-5,-4)
Well.. divide 90 into 60, so 1.5 this means 1.5 hours, and then add it to 1:30 which is = 3:00 o'clock
