Mavis drives = 634 miles.

Mavis visits her grandmother 4 times.

That means, she drives 634 miles each time when she visits her mother.

One time round trip Mavis's house to her gramdmother in philadelphia = 634 miles.

If she visited 4 times, we can multiply one round trip distance by 4 or we can just add that distance four times.

Let us try it by multiplying 4 by 634 .

If we multiply 4 by 634, we get 2536.

Therefore, 2536 miles Mavis drives if she visits her grandmother 4 times.

If for a dog 1 year is 7 ears for them, how many hours in 24 hours is one day for dogs?
Arisa [49]

Answer:

168hrs in division terms of every 1 year x 7 etc...

It will always be 24hrs nothing changes set of units to same units.

However because the equivalent to a same length of life as human is 1/7 we can do the reciprocal = 7 and do 24 x 7 = 168 hrs, but as many younger and healthy dogs eat and sleep the same as humans then equivalent would be not a good way to compare a dogs life.

Longer life breeds like Labrador or mixed breed dogs if walked at least 4 times a day and away from other dogs and all day young kids can live older than 20 and have actually be more compared to 4-5 years and so the comparison would be like 96 hrs or 120 hrs, but hours stay 24 a day for all animals as units don't change same units. Day represents a day and a year represents sun rise to sun fall to sun rise again x 365.

Find the error, Rashid and Tia solve the quadratic equation (2x2-8x +10=0) by completing the square. Who is correct? Explain you
podryga [215]
To solve a quadratic equation using completing the square method,
STEP 1
Divide through by the coefitient of the squared term.

Looking at the solutions of Rashid and Tia, we notice that Rashid did not divide through by the coefficient of x^2.

Therefore, Rashids solution is wrong.

We solve the equation using completeing the square as follows:
2x^2-8x+10=0 \\  \\ x^2-4x=0-5=-5 \\  \\ x^2-4x+4=-5+4=-1 \\  \\ (x-2)^2=-1 \\  \\ x-2=\pm i \\  \\ x=2\pm i
