Step-by-step explanation:
Which of these division problems have the same quotient as 12.3 divided by 0.4? Check all that apply.
A. 123 ÷ 4
B. 1.23 ÷ 0.4
C. 1,230 ÷ 40
D. 123 ÷ 0.04
Answer:
The answer is A and C
Step-by-step explanation:
The answer is A because 12.3 multiplied by 10 is 123, and 0.4 multiplied by 10 is 4.
12.3 * 10 = 123
0.4 * 10 = 4
So, this shows that this equation is the same as 12.3 divided by 0.4
The answer is C because 12.3 multiplied by 100 is equal to 1230, this is the same for 0.4
12.3 * 100 = 1230
0.4 * 100 = 40
So, the answer is both A and C.
Hope this helps! :)
Answer:
12.3 divided by 0.4 is 30.75
Step-by-step explanation:
You then go to letter A and 123/4 is also 30.75
but you go through the rest of the choices just in case.
B is 3.075 so that is incorrect
C is 307.5 so that is also incorrect
D is 3075 and that is incorrect and not 30.75.
Therefore your answer is A.
30.75 = 30.75.

What is multiplication?Multiplication is a process of adding a number repetitively. Mathematically, we can write -
m = a x b
Given is that the 5 liters of paint costs Rs. 75.
5 liters of paint costs Rs. 75.
1 liter of paint will cost Rs. (75/5)
15 liters of pain will cost Rs. (75/5 x 15) = 75 x 3 = Rs. 225
Therefore, 15 liters of pain will cost Rs.225

Paki answer po fi d the value of k mentally
Answer:
We have 5 equations where we want to find the value of k. To find the value of k first solve the term that is multiplicating k, and when we know the term, we can divide both sides to isolate k in one side of the equation.
1) 30 = k*(15/4)
To solve this, we can just multiply by (4/15) in both sides, so we get:
30*(4/15) = k*(15/4)*(4/15)
(30/15)*4 = k
2*4 = k
8 = k
2) 360 = k*√36
Here you need to remember that:
6*6 = 36
then √36 = 6
We could just replace that in the equation:
360 = k*6
now let's divide both sides by 6.
360/6 = k*6/6
60 = k
3) 64 = k*(4²)*(2²)
Here we need to remember that:
4² = 16
2² = 4
We can replace these in the equation to get:
64 = k*16*4
and 4*16 = 64
then:
64 = k*64
Now let's divide both sides by 64.
64/64 = k*64/64
1 = k
4) 100 = k*(25)*(4)
Here we know that 4*25 = 100
So replacing that in the equation we get a similar expression to the above one.
100 = k*100
Now let's divide both sides by 100
100/100 = k*100/100
1 = k
5) 6 = k*3
Here just divide both sides by 3.
6/3 = k*3/3
2 = k

How many units down does susan need to move to get to the fourth point on the number line a. 1/2 b. 3/2 c. 2 d. 4 e. 6
Answer:
e. 6
Step-by-step explanation:
Hello there!, since there is no prior information concerning the activities performed by Susan, I will explain what a number line is and try as much as possible to answer your question from the definition.
A number line is a line on which integers are usually drawn as points separated by a uniform distance. This way, the number line makes addition and subtraction easier, which is very useful when you want to teach someone these operations.
Now, let assume Susan starts from 0 on the number line, to get to the fourth point, Susan needs to move 4 blocks, where each block contains 10 units.
Now, let's assume that Susan is at the third block and the fourth unit, it will take Susan an additional 6 units to get to the fourth point.
NOTE: The solution to this question was provided based on assumption since no much information was given in the question.

1. A pair of shoes is regularly priced at $52. They are on sale for 15%
off the regular price. What is the sale price of the shoes?
[tex]52 \times 0.15 = 7.8[/tex]
[tex]52 - 7.8 = 44.20[/tex]
The sale price of the shoes is $44.20
Answer:
52*15/100=7.8$ so u will take away 7.8$ from 52$=44.2$ he has to pay.
Richard bought a pair of shoes for $37.00, a tie for $22.00, and a new belt for $17.00. If the sales tax is 7.5%, how much sales tax did Richard pay for these items?
It seems to me, that if you were to add the price of all three items together, then multiply by 7.5%, you'd have the answer. Remember that 7.5% = .075 ... in other words, that is the number you would multiply the sum of the items by. Does that help?

Amanda has $56.10 in her bank account in March. In May she has 4 times as much money in her account than she did in March. In June she adds $75.22 to her account. How much money does Amanda have in her account in June?
Answer:
$299.62
Step-by-step explanation:
Amanda has $56.10 in his bank account in march
In May he has 4 times this money
= 56.10×4
= 224.4
In June she add $75.22 to the money
= 224.4 + 75.22
= 299.62
Hence in June Amanda has $299.62 in her account
10/27=a/135
what is the answer for this equation?
Answer:
So we have this equation:
10/27 = a/135
What we can do is multiply both sides by 27 and 135:
10*135 = a * 27
1350 = 27a
a = 1350/27. = 50.

What s proportionality in mathematics?
If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
If equivalent elements in two sequences have a constant product, also known as the coefficient of proportionality, then the two sequences are inversely proportional.
The shadow of a 25 m tall flagpole casts is = 10 m.
Let the height of the office building = x m.
The shadow of a x m tall office building is = 26 m.
From theory of directly proportionality:
25 : 10 = x : 26
25/10 = x/26
x = (25/10)×26 = 65
Hence, the height of the office building is 65 meter.
