Answer:
Jake is incorrect with his methodology for solving these problems
Step-by-step explanation:
Jake is incorrect with his methodology for solving these problems. This is because dividing a number by 10 requires moving the decimal point one digit to the left. When dividing 630 by 10, removing the zero works because by moving the decimal one digit to the left we would simply drop the zero and the decimal would not be needed leaving the answer as 63. However, this does not work on numbers that already have a decimal such as 35.270. This number divided by 10 would be 3.527 but simply removing the 0 like Jake states would give us the incorrect answer of 35.27
Answer:
19 Cars
Step-by-step explanation:
Write a linear equation:
y=7x+53
Y = Total money
X = cars parked
If we want to earn 186 dollars a day then sub y for 186 and solve x:
186=7x+53
186-53=7x
133=7x
7x=133
x=133/7
x=19
This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
<span><u><em>The correct answer is: </em></u>
D) neither the relation (length, volume) nor the relation (volume, length) is a function.
<u><em>Explanation: </em></u>
A function is a relation in which each element of the domain is mapped to no more than <u>1 element</u> of the range.
For (length, volume), the domain would be length and the range would be volume.
There could possibly be a length value that is mapped to more than one volume value, depending on the height of the pool. This means that (length, volume) is not always a function.
For (volume, length), volume is the domain and length is the range.
There could possibly be a volume that is mapped to more than one length, depending on the height of the pool. This means that (volume, length) is not always a function either.</span>
Answer:
x = 15
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 20² = 25²
x² + 400 = 625 ( subtract 400 from both sides )
x² = 225 ( take the square root of both sides )
x = 
= 15
