300 x 400 = 1200 the same as 3 x 4 = 12
Answer:
3x4=12 is 300x400=1200 but it is not multiplied by 100
Step-by-step explanation:
Answer:
Step-by-step explanation:
Definitely not, although in both cases you are multiplying 3 by 4, obtaining 12.
300 * 400 = 3*4*100*100 = 12*10^4, or 12*10000, or 120000, which is not the same as 12.
Simplify the expression:

Answer:
12 times 5=60 not 70
Step-by-step explanation:
12(5+2y)=4y-(5-9y
60+24y=4y-5-9y
60+24y=-5y-5
29y+60=-5
29y=-65
y=-65/29 or y= about -2.38

why dividing by 0 is undefined?
Answer:
In standard math, the articulation has no importance, as there could be no number which, when duplicated by 0, gives a (expecting to be a ≠ 0), thus division by zero is indistinct. Since any number increased by zero will be zero, the articulation 00 is additionally unclear; when it is the type of a breaking point, it is a vague structure.
Step-by-step explanation:
Answer:
In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 0. 0 is also undefined; when it is the form of a limit, it is an indeterminate form.

(Help me please) what can you tell about the mean of each distribution
Answer:
The distribution is considered the mean in the problem
Step-by-step explanation:
$124.84 - $19.75 = $105.09
If you can consider what the mean is in math: How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.
Answer:
1 and 1/4 liters of paint are needed for one door
Step-by-step explanation:
You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 and 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.
Hope this helps!

Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)
Answer:
Perimeter of a square=circumference of circle
4×22=2πr
44=πr
r=14
Area of circle=πr2
22/7×14×14
28×22
616
Answer:
176cm²
Step-by-step explanation:
Side of square = 22cm
Perimeter of square = 88cm
Circumference of circle = perimeter of square
2π r = 88cm
2 x 22/7 x r = 88cm
44/7 x r = 88cm
r = 88 x 7/44
r = 14cm
Area of circle = π x r x r
= 22/7 x 14 x 14
= 44 x 4
= 176 cm²
For a science experiment, Annie removes a cold liquid from a refrigerator and measure it's temperature every 1/2 minute. Annie finds that the temperature increase by
1 and 3/4 degrees Fahrenheit. What is the rate per minute of the temperature increase?
Answer:
2 1/2
Step-by-step explanation:
1/2 minute = 1 3/4 degrees fahrenheit.
1 minute = 2 1/2 degrees Fahrenheit.
you can take 1 3/4 + 1 3/4 and get the Answer.

[A] is making 25 sundaes with mint, chocolate, and vanilla ice cream.
3/5 of the sundaes are mint ice cream and 1/2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
5 sundaes
Step-by-step explanation:
find the GCF: 5
so 3x5 would be 15
15 mint.
25-15=10
10/2=5
boom
There are [tex]$5$[/tex] sundaes will be vanilla ice-cream.

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
It is given that, there is [tex]$25$[/tex] sundaes with mint, chocolate and vanilla flavor ice cream out of these [tex]$\frac{3}{5}$[/tex] of the sundaes are mint flavor and [tex]$\frac{1}{2}$[/tex] are chocolate flavor.
We have to find the number for sundaes will be vanilla flavor ice-cream.
So,
We have to multiply [tex]$3$[/tex] by [tex]$5$[/tex] and solve it.
So,
[tex]$3\times 5=15$[/tex]
There are [tex]$15$[/tex] mints flavor.
Now,
Divide total number of sundaes with all flavor ice-cream by calculate value for mint.
We get,
[tex]$25-15=10$[/tex]
Multiply the above calculate value by no. of remaining sundaes for chocolate ice-cream.
So,
[tex]$10\times \frac{1}{2}=5$[/tex]
Hence, there are [tex]$5$[/tex] sundaes will be vanilla flavor ice-cream.
