In movies Box office does not equal quality.

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

PLEASE RESPOND QUICK WITH THE CORRECT ANSWER OR YOU WILL GET REPORTED (08.03)Magdeline wants to know if the number of words on a page in her computer science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book. Book Mean Median Mean Absolute Deviation Computer science 48.7 40 9.4 Math 34.2 45 1.9 She claims that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page. Based on the data, is this a valid inference?

Method 1: The owner asked every third customer to rate all the pizza toppings in order of preference. Method 2: The owner gave all customers a toll-free telephone number and asked them to phone in their topping preferences. Method 3: The owner asked the preferences of every other teenager who entered the pizzeria. Method 4: The owner reviewed the pizzeria’s complaint cards and assessed all complaints related to pizza toppings. Which method is most likely to give a valid generalization

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

Answer:

60 feet

Step-by-step explanation:

The area of the school is

165(300) = 49500 square feet.

The area of the parking lot with the school is

(165+75)(300+75) = 240(375) = 90000 square feet.  This means the area of just the parking lot is

90000-49500 = 40500 square feet.

The area of the new expanded lot will be doubled; this means it will be

2(40500) = 81000 square feet.  Adding back the area of the school, this means the total lot will be

81000+49500 = 130500 square feet.

The width will be 375+x and the length will be 240+x; this gives us

130500 = (375+x)(240+x)

Multiplying the binomials gives us

130500 = 90000+375x+240x+x²

130500 = 90000+615x+x²

To solve this, we first set it equal to 0.  We do this by subtracting 130500 from each side:

130500-130500 = 90000+615x+x²-130500

0 = x²+615x-40500

We will use the quadratic formula:

x=frac{-bpm sqrt{b^2-4ac}}{2a}

Substituting our values for a, b and c,

x=frac{-615pm sqrt{615^2-4(1)(-40500)}}{2(1)}\\=frac{-615pm sqrt{378225--162000}}{2}\\=frac{-615pm sqrt{378225+162000}}{2}\\=frac{-615pm sqrt{540225}}{2}\\=frac{-615pm 735}{2}\\=frac{-615+735}{2}text{ or }frac{-615-735}{2}\\=frac{120}{2}text{ or }frac{-1350}{2}\\=60text{ or }-675

We do not use negative numbers for measurement, so x = 60.
