Answer:
y = 1/5x + 2 1/5
Step-by-step explanation:
since the slope of the line in the equation given is -5 the perpendicular slope to that will be the opposite reciprocal which is 1/5
Then plug x, y and m into y = mx + b
3 = 1/5 (4) + b
3 = 4/5 + b
2 1/5 = b
Write equation
y = 1/5x + 2 1/2
Answer:
45-(-15)
430-(-180)
11,560-(-185)
Step-by-step explanation:
just add the two numbers together for diffrence.
The heat released or absorbed by a substance is calculated through the equation,
H = mcpdT
where H is teh heat,
m is the mass,
Cp is the specific heat, and
dT is the temperature difference
In this item, since both nails are identical, m and cp for both nails are equal such that the equation can be expressed as,
mcp(95 - x) = mcp(x - 15)
where x is the final temperature. Solving for the value of x from the equation derived above will give us a final answer of 55 degrees C.
Answer: 55°
Answer:
Step-by-step explanation:
There are 1,400 daffodils in the flower garden covering an area of 345 square feet. So, the area covered by 1 daffodil, the unit rate, is found as shown below.
Now, use the unit rate to determine the area required to have 250 more daffodils as shown below.
Therefore, the area required to add 250 daffodils is approximately 61.6 square feet.
