Answer:
4.
l=22cm
b:16cm
h:10cm
surface area =2(lb+bh+lh)=2(22*16+16*10+22*10)
=1464cm²
5.
a=2.5dm
area cubical soda cracker box=6a²=6*2.5²=37.5dm²
6.
r=1.5dm
area of ball=4πr²=4π×1.5²=28.27dm² per ball
for 10 bal =28.27×10=282.6dm²
Remember y=mx+b
Since y=2 that means it is a horizontal line at 2 on the y axis which means it does not have a slope. The slope would be zero.
Answer:
B
Step-by-step explanation:
Let's create an equation in point-slope form, which is: 
, where 
is the point and m is the slope.
Here, our point is (-2, 7) and our slope is m = -5 so plug these in:
Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:
2 - 7 = -5(a + 2)
-5 = -5(a + 2)
Divide by -5:
1 = a + 2
Subtract 2 from both sides:
a = -1
Thus, the answer is B.
Hope this helps!
Answer:
80/7 simplified its 11 3/7
Step-by-step explanation:
lmk if you need an explanation! :]
To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows
12's:
0 0 = 12 x0
1 2 = 12 x1
2 4 = 12 x2
3 6 = 12 x3
4 8 = 12 x4
6 0 = 12 x5
7 2 = 12 x6
8 4 = 12 x7
9 6 = 12 x8
10 8 = 12 x9
12 0 = 12 x10
13 2 = 12 x 11
14 4 = 12 x 12
