Answer:
2550 miles in 6 hours
Step-by-step explanation:
if you divide the miles and hours by each other you will get the m/ph (miles per hour)
3400 ÷ 8 = 425
now, that we know the plane travels 435 m/ph, then if we multiply it by 6 we will get the answer
425 × 6 = 2550
Answer:
The lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
Step-by-step explanation:
The Mom's plot is longer in ranges, therefore, she would have more variability than the dad.
y=x^2 + x - 2
x + y = 1
Replace y in the second equation:
x + x^2 + x -2 = 1
Simplify:
x^2 + 2x -2 = 1
Subtract 1 from both sides:
x^2 + 2x -3 = 0
Factor:
(x-1) (x+3) = 0
Solve for both x's:
x = 1 and x = -3
Now replace x in the second equation and solve for y using both x values:
1 + y = 1, y = 0
-3 + y = 1, y = 4
Now you have (1,0) and (-3,4) as solutions for (x,y)
XY = x times y:
1 x 0 = 0
-3 x 4 = -12
The answer would be -12
Nine less than a number

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.
