See Explanation

Step-by-step explanation:

A positive integer is a perfect square if it can be expressed as the product of two same positive integers.

Any number that cannot be written this way is a non-perfect square.

Since the integers are not presented, we will quickly examine the perfect squares between 1 and 50.

The perfect squares are: 1,4,9,16,25,36 and 49.

1=1 X 1
4=2 X 2
9=3 X 3
16 =4 X 4
25 =5 X 5
36 =6 X 6
49 =7 X 7

Every other positive integer in the numbers 1-50 apart from those listed above is a non-perfect square.

Lisa is currently taking physics as one of her electives in school. her grade at the end of the year is determined by the averag

ICE Princess25 [194]

The score which Lisa should get in her fourth exam of school to get exactly 80% in the course is 64.

<h3>What is the average of a group of numbers?</h3>

The average of the group of numbers is the ratio of the sum of all the numbers of the group to the total number of the group.

Lisa is currently taking physics as one of her electives in school.

Her grade at the end of the year is determined by the average of four exams, each worth 100 points.

On her first test, she got an 84,
On her second, she got a 92,
On her third, an 80.

She got exactly 80% in the course. Let she scores x marks in her fourth exam. Thus,

$\dfrac{84+92+80+x}{4}=80\\256+x=80\times4\\x=320-256\\x=64$

Hence, the score which Lisa should get in her fourth exam of school to get exactly 80% in the course is 64.

Matt buys a new fish tank. The fish tank is in the shape of a cuboid. The diagram shows water in the tank. 30 cm 30 cm 100 cm Ma

lyudmila [28]

Answer: Yes, but only if he houses 37, 38, 39, or 40 fish

Anything larger than 40 and he'll need more room.

==========================================================

Explanation:

The tank is 30 cm by 30 cm by 100 cm. The volume is 30*30*100 = 90,000 cm^3 which is shorthand for "cubic centimeters".

We're told that 1000 cm^3 = 1 liter, which means the 90,000 cm^3 converts to (90,000)/(1000) = 90 liters.

The fish tank is 90 liters.

Since 1 gallon = 4.5 liters, this means the 90 liter tank converts to 90/(4.5) = 20 gallons

----------------------------

Your teacher mentions "He can keep 2 small fish for every 1 gallon".

Since the tank is 20 gallons, that means he can keep 20*2 = 40 fish. This value is larger than 36, so Matt is correct to a point. If Matt is thinking 37, 38, 39, or 40 fish then he would be correct. If Matt is wanting more than 40 fish, then he'll need a bigger tank.

In short, he can't have any number over 36 and can only have 4 specific values (the four values mentioned earlier).

So technically, Matt is correct, but strong clarification is needed.

Find the slope.....<br>

Luden [163]

Answer:

slope = 1/2

Step-by-step explanation:

slope = y2-y1 / x2-x1

1 - -2 / 4 - -2 = 3/6 = 1/2

or think of it this way. for every 1 step up you take 2 steps to the right to stay on the line. 1/2
