Answer:
31
Step-by-step explanation:
If we assume the number of potatoes is proportional to the weight, then we can write the equation ...
n/10 = 10/3.2
n = 100/3.2 = 31.25 . . . . . . . multiply by 10
There may be 31 potatoes in a 10-lb bag.
Answer:
$36
Step-by-step explanation:
1. Determine the surface area of the largest jaw breaker
Surface area of a sphere = 4πr²
4 x 3.14 x 2² = 50.24in²
2. Determine the surface area of the new jaw breaker
4 x 3.14 x 6² = 452.16 in²
3. Determine the cost per area
4/ 50.24
4. Determine the price for the new jaw breaker
4/ 50.24 x 452.16 = $36
You want to find the equation for a line that passes through the point (-1,5) and has a slope of 4.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 4. So you can right away fill in the equation for a line somewhat to read:
y=4x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-1,5). When x of the line is -1, y of the line must be 5.
Answer:
Decreased.
Step-by-step explanation:
Decrease means to go down or take away, therefore in a mathematical equation, it would be represented by a negative integer.
Change could be positive or negative
each is a singular description word
and drastically is just describing how fast.
have a good day!
It's 8n meaning 8 times n (8*n) so for example for 5 nights she would sleep : 8*5 = 40 hours in total.
