Answer:
900 yd²
Step-by-step explanation:
You can draw the pattern that would need to be folded to make the figure, then find the area of that pattern (or "net"). It consists of a rectangle 10 yards wide and 60 yards long, together with another that is 20 yards long and 15 yards wide. The total area is the sum of these ...
... area = (60 yd)(10 yd) + (20 yd)(15 yd)
... = 600 yd² +300 yd²
... = 900 yd²
x=8 is the answer fellow user
7.8 times 10^5
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 780,000
New Number: 7.80000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 7 . 8 0 0 0 0
Decimal Count: 1 2 3 4 5
There are 5 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 7.8 (Please notice any zeroes on the end have been removed)
b = 5
Now the whole thing:
7.8 x 10^5
Step 4
Check your work:
10^5 = 100,000 x 7.8 = 780,000
Answer:
y = m x + b
y = -5 x + b given m
b = y + 5 x = 3 + 2 * 5 = 13
y = -5 x + 13 final equation
Check: if x = 2 then
y = -5 * 2 + 13 = 3
