Answer:
1/2
2
Step-by-step explanation:
y = 1/2x - 4 (the slope for this line is 1/2)
y = 2x - 3 (the slope for this line is 2)
Hope this helps!
If i read this correctly it should be $90. 10x5= $50 and that plus $40 equals $90 altogether
20 students.
40% are boys. (40/100)*20 = 0.4 * 20 = 8 boys.
Girls= 20 - 8 = 12 girls.
25% of the boys wear glasses. = (25/100)*8 = 0.25*8 = 2 boys wear glasses.
50% of the girls wear glasses. = (50/100)*12 = 0.50*12 = 6 girls wear glasses.
Total students that wear glasses = 2 + 6 = 8 students.
8 students wear glasses.
Explecit formula
hmm, seems to be a geometric sequence
so
an=a1+d(n-1)
d=common differnce
a1=first term
given
a1=firstterm=9.2
and the difference between each tierm is 1.8
an=9.1-1.8(n-1) is da equation
so 4th option
Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
