at 9am the outside temperature was -3 degree by the noon the temperature was 12 degree a news reporter said it was getting warmer outside.why is this incorrect?

Answers

Answer 1

Answer: Because of wind chill, they may say that the way it feels is -3, but it was probably much warmer, but later (at 12 degrees) they were probably reporting actually temp.
This is my best guess.

URGENT!! The difference between the roots of the quadratic equation x2−12x+q=0 is 2. Find q

Answers

Answer:

q=35

Step-by-step explanation:

x2 - 12x + q = 0

Let the two roots be r and r+2.

Factor the quadratic expression:

(x - r)[x - (r + 2)] = 0

Expand, simplify, group like terms, and get

x2 - 2(r + 1)x + r(r + 2) = 0

Compare to

x2 - 12x + q = 0

and set equal the coefficients of like terms:

Coefficient of x:

-2(r + 1) = -12 ⇒ r + 1 = 6 ⇒ r = 5

(Then the other root is r + 2 = 5 + 2 = 7)

Constant term:

r(r + 2) = q ⇒ 5(5 + 2) = q

q = 35

Test the solution:

(x - 5)(x - 7) = x2 - 12x + 35

With two roots differing by 2, you get an equation of the form

x2 - 12x + q = 0

with q = 35.

According to the pedometer i move 27 5/8 inches when i walk How many feet i will travel in 96 steps?

Answers

I am assuming that is how far you move per step? So, what I did was first multiply 27 5/8 by your 96 steps ( I also converted 5/8 into a decimal so it would be easier so it's 27.625) 27.625*96= 2,652. I divided that by 12 so I could turn that into feet instead of inches; 221 feet.

A right triangle has an area of 50 square inches. If the triangle is an isosceles triangle, what are the lengths of the legs of the triangle?

Answers

area=1/2bh
50=1/2bh
times 2
100=bh
solve for b
divide by h
100/h=b
we hav to make a drawing
since it is isocoleese
h=b
100=b^2=h^2
h=b=10
answer is 10 inches

10in and 10in, because 10x10=100, and 100/2=50

What does 2/3 x 2 equal! Someone please help as soon as possible!

Answers

The first step we have to do is: 2/3 × 2. If it is multiplying a whole number to a fraction, multiply the whole number by the numerator. In this case, the numerator is 2, so we can do: 2 × 2 to get 4.

From multiplying, our new fraction would look like: 4/3. You can keep it as an improper fraction or you can turn it into a mixed fraction. To do so, divide the numerator by the denominator (4 ÷ 3) to get the answer of 1.3333, Keep the original denominator, write the remainder as the numerator, and whatever whole number you get, goes in front of the fraction. Since 4 ÷ 3 = 1 with a remainder of 1, we can keep the denominator, and switch out the numerator with 1, and also the whole number.

The answer as an improper fraction: 4/3
The answer as a mixed fraction: 1 1/3
The answer as a decimal: 1.3333
