Answer: D. 1,120 cm2
Step-by-step explanation: Perimeter is the adding of all four sides, so if you take the width and add it with itself, you can then subtract the perimeter with the added width. Now with this new number all you have to do is divide it by two, and now that you have the length you can multiply it with the original width to get the area.
Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs?
Example:
3x + 12 ≤ 35
3x + 12 - 12 ≤ 35 - 12
3x ≤ 23
3x/3 ≤ 23/3
X≤ 7.6667
(solve it like that please) ASAP
Answer:
So the answer is 3 and an half of a hour(3.5 hours)
Step-by-step explanation:
$8 times 3 = 24 + the $2 he has =$26 + half an hour($4) =$30
8 times 3 = 24
plus $2 = $26
since he gets $8 for an hour of work and we only need $4, we can make him work half an hour
so $26 + $4 =$30

A pitcher's earned run average is the number of earned runs allowed per game of 9 innings. A pitcher allows 20 earned runs in 50 innings. What is the pitcher's earned run average?
Answer:
Step-by-step explanation:
In baseball statistics, earned run average (ERA) is the average of earned runs given up by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.
The pitcher's earned run average is 3.6.
We are given that;
Number of innings=9
Now,
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
To find the pitcher's earned run average, we need to divide the number of earned runs by the number of innings, and then multiply by 9.
This is because we want to find the average number of earned runs per 9 innings, which is the standard length of a game.
Using this method, we get:
[tex]$\frac{20}{50} \times 9 = 3.6$[/tex]
Therefore, by unitary method answer will be 3.6.

The table shows the battery life of four different mobile phones:

B 25

D 18
If 8.45% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.69 hours of battery life in a day?
Phone A
Phone B
Phone C
Phone D
Answer:
Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845
If you want to compute out the four results with a calculator, then it would look like this:
0.0845*20 = 1.69
0.0845*25 = 2.1125
0.0845*10 = 0.845
0.0845*18 = 1.521
and this shows that no other result (but choice C) is close to 0.8
So that's why the answer is choice C

Kato must write 60 percent of a 20-page report by tomorrow. Kato wants to determine the number of pages that he needs to write by tomorrow. Kato’s work is shown below.
Step 1: Write 60 percent as a ratio. part/whole = 60/100
Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator.
Step 3: 100 divided by 20 = 5
Step 4: 60(5) = 180
What mistake did Kato make?
In Step 1, Kato should have written the ratio as 100/60.
In Step 2, Kato should have put 20 in the numerator.
In Step 3, Kato should have multiplied 100 by 5.
In Step 4, Kato should have divided 60 by 5.
Rebekah has $400 to spend on a video game system and games. The system cost $289.99 and each game costs $32.29. How many games can she buy with the game system?
A- No more than 2 games
B- No more than 3 games
C- No more than 4 games
D- No more than 5 games
Answer:
B- No more than 3 games
Step-by-step explanation:
add 32.29 to 289.99 until you get close to 400 without going over 400.
To find the number of distributed quantities, division operator is used. She can buy 3 games.
What is Division ?Division is process of dividing two numbers. The result of division is the quotient and the remainder. When remainder is zero, the factors of a number are found.
Total amount to be spent on game system and games = $400.
The cost of the system = $ 289.99
The cost of each game = $ 32.29
Thus, the total amount left for buying games is the difference of the total amount and the cost of the system.
It is given as follows,
Amount left for buying games = 400 - 289.99
= $ 110.01
Now, total number of games to be bought can be calculated by dividing the remaining amount by the rate of each game as below,
Total number of games = 110.01/32.29
= 3.406
Since the number of games cannot be a decimal value, approximate 3.406 to 3.
Hence, the number of games Rebekah can buy is 3.

Condensation-water which collects as droplets on a cold surface when humid air is in contact with it: the conversion of a vapor or gas to a liquid:
Pressure-is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
Temperature-Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder.
Thermal energy-Thermal energy refers to several distinct physical concepts, such as the internal energy of a system; heat or sensible heat, which are defined as types of energy transfer (as is work); or for the characteristic energy of a degree of freedom in a thermal system
