What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
Answer:
2,3 &13
Step-by-step explanation:
78=2times39=3times13
therefore the prime factors of 78=2,3,13
First we need to know the surface area of the package:
2(lw) + 2(lh) + 2(wh)
2(8*11) + 2(11*2) + 2(8*2)
2(88) + 2(22) + 2(16)
176 + 44 + 32
252 square inches needed
Wrapping paper is in feet, so convert it to inches before finding the area.
1' = 12"; 2' = 24"
12* 24 = 288 square inches.
So, yes there is enough paper to cover all sides of the gift if there are no overlaps.
Answer:
C). 0 degrees
Step-by-step explanation:
The given equation is:
-4 + 6 sinx = -4 + 4 sinx
adding 4 on both sides:
4 - 4 + 6 sinx = 4 - 4 + 4 sinx
6sinx = 4sinx
dividing by 2 on both sides, we get:
6sinx/2 = 4sinx/2
3 sinx = 2 sinx
subtracting 2 sinx from both sides we get:
sin x = 0
x = sin⁻¹ (0)
x = 0 degrees
Answer:
1:4
Step-by-step explanation:
24/2=12
6/2=3
12/3=4
3/3=1
So the ratio is 1:4
