To graph y-3x>-2, find the boundary line. (y > -2 + 3x is your answer)
1. Find the equation of the boundary line.
2. Choose a point (x, y) on the shaded side on the line.
3. Plug x and y, in the boundary to identity the inequality sign.
Answer:
30,000
Step-by-step explanation:
So let’s look at the numbers, It’s 3,30,300, 3000. It looks like they are 10x each next number. So the next one should be 30,000
Finding the value of w
We want to find the value of w that makes m = 8 in the equation:
m = w - 4
We just replace m by 8 in the equation:
m = w - 4
8 = w - 4
We add 4 both sides of the equation:
8 + 4 = w - 4 + 4
8 + 4 = w
12 = w
Then
<h2>if w = 12, then m = 8</h2>
Answer:
78
Step-by-step explanation:
Given that:
First day (a) = 1
1 more pebble every subsequent day than the previous day
Tn = a + (n - 1)d
d = common difference ; difference between pebbles in two successive days = 1
n = nth day
At the end of the 12th day;
Tn = a + (n - 1)d
T(12) = 1 + (12 - 1) 1
T(12) = 1 + 11
T(12) = 12
Appling the sun if arithmetic progression formula : Sum of AP:
n/2 (a + Tn)
n = number of terms
12/2 (1 + 12)
6(13)
= 78
Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw
so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2
split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3
