If you would like to know how long will take you to paint one wall, you can calculate this using the following steps:
1/3 of a wall ... 1/4 hour1 wall ... x hours = ?
1/3 * x = 1/4 * 11/3 * x = 1/4 /*3x = 1/4 * 3x = 3/4 hour
Result: It will take you 3/4 hour to paint one wall.
Answer:
70 amps
Step-by-step explanation:
The current I is inversely proportional to the resistance R
I=k/R (k is the constant of proportionality)
A) I=210 amperes
R=4 ohms
I=k/R
k=I×R
k=210×4=840
B) R=12 ohms
k=840
I=k/R
I=840/12=70 amperes
Answer:
<em>The first value is ten times greater.</em>
Step-by-step explanation:
<u>Numbering System</u>
When we represent numbers in the decimal system, each digit to the left has a value 10 times more than the digit to the right. For example, in the number 44, the 4 to the left side has a value of 40, and it's neighbor to the right side has a value of 4.
In the number 76,600, the 7 has a value of 70,000, while in the number 7,600, its value is 7000. Thus the first value is ten times greater.
We need to write an expression for "add 34 and 6 and then multiply 3"
"Add" represents + operation .
"multiply" represents × operation.
We need to add 34 and 6.
So, we can write 34+6 and then we need multiply the sum by 3.
So, we need to keep above addition of 34 and 6 in parantehsis. We get
(34+6) × 3.
So, the final expression is (34+6) × 3.
