Answer:
1/3
Step-by-step explanation:
3x – 9y = 4
We need to solve for y
Subtract 3x from each side
3x – 9y-3x = 4-3x
-9y = -3x+4
Divide each side by -9
-9y/-9 = -3x/-9 +4/-9
y = 1/3 x -4/9
This is in the form y = mx+b where m is the slope and b is the y intercept
y =1/3x -4/9
The slope is 1/3
U just multiply them. V=A*h=96ft^3
Answer:
- trailing zeros are dropped
- 1846 beats
- 42×(selling price for 1 tin)
Step-by-step explanation:
41. The product of 0.25 and 0.4 is 0.100, with three decimal places. Trailing zeros are usually dropped--except when they are used to indicate significant digits in a calculation. Hence, the usual presentation of the result is ...
0.25 × 0.4 = 0.1
__
42. To find total beats, multiply beats per second by seconds.
(52 beats/second)(35.5 seconds) = (52)(35.5) beats = 1846 beats
The hummingbird's wings will beat 1846 times in 35.5 seconds.
__
43. To find total sales for the week, multiply the price of a tin of popcorn by the number sold in the week (42).
7x=91 . divide 7 on both sides making the answer 13 bc 91/7 is 13
8-4 = 4, 4÷2=2 answer is 2
