One evening, 2/3 of Mrs. Thorne's, students watched a reality television show. Mrs. Lombardo's students, 4/5 watched the same reality show. Which teacher had more students that watched the reality show? Explain

Answers

Mrs.Lombardo.if you do the math out, 4/5 and 2/3 give you an LCD (Least Common Denominator) of 15, so this means 4/5 = 12/15, and 2/3 = 10/15. 4/5 is greater than 2/3.

Answer:

multiplication property of equality

Step-by-step explanation:

Since we are multiplying by the same amount on each side, we are using the multiplication property of equality

Answer: Multiplication Property of Equality

Step-by-step explanation:

This property states that while simplifying an expression, you can multiply both sides of the equation by any number, and it will stay true. This property is useful here, because multiplying a fraction by its reciprocal = 1, so the expression would become 1x=-128.

An apple pie is taken out of the oven with an internal temperature of 325 degrees F. It's placed on a rack in a room with a temperature of 72 degrees F. After 10 minutes, the temperature of the pie is 200 degrees F. What will be the temperature of the pie 30 minutes after coming out of the oven?

Answers

so the answer that Yunuzaj put is correct
to account for the room tempurature you would have to find some complicated equation to solve this but you could assume that the tempurature rate would slow down as it gets closser to room tempurature

if you didn't have to account for the room tempurature
the ending tempurature would be -50 degrees F
because 325-200=125
so 125=10
10 times 3=30
so
125 times 3=375
325-375=-50F

In 10 minutes the pie dropped 125 degrees, so we can assume in another 10 minutes it will drop another 125 degrees, and in another 10 minutes 125 degrees, but this brings us down to zero degrees. But it says it's kept at 72 degrees. So we can assume the pie will remain at 72 degrees

Solve for u. -24 = u ÷ 6

u = ____

Answers

The value of u is -144

Solution:

Given that,

$-24 = u / 6$

We have to solve for "u"

From given,

$-24 = u / 6$

Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign

Thus we get,

$-24 = u * (1)/(6)\n\n(u)/(6) = -24$
