The mass of 1 L of water is 1 kg. The mass of gasoline is 0.68 times the mass of water. What is the mass of the gasoline in a full tank that holds 75 L.
Answers
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.
What is the mass?
Mass refers to the quantity of matter in an object. Mass is generally measured by how much something weighs. The more matter something has, the more it will weigh.
Here given that,
The mass of [tex]1[/tex] L of water is [tex]1[/tex] kg. The mass of gasoline is [tex]0.68[/tex] times the mass of water.
As we know,
[tex]1L=1000ml[/tex]
So, [tex]0.68[/tex]×[tex]1000=680grams[/tex]
As per this the mass of water is greater than the mass of gasoline.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12
Answers
y - 2/3 = -2 (x - 1/4)
First you distribute the -2 because it is the first order of operation
y - 2/3 = -2x + 1/2
Then you add 2/3 on both sides because we want to isolate y
y = -2x + 1/2 + 2/3
Then we combine like terms
y = -2x + 7/6

What would you divide the numerator and denominator by to put 16/24 in simplest form?
Answers
Answer:
8
Step-by-step explanation:
if you divide the numerator by 8 you get 2 and divide the denominator by 8 and you get 3
the simplest form would be 2/3 which was divided by 8
Answer:
Divide both numerator and denominator by 8.
Step-by-step explanation:
Firstly, find the greatest common factor (GCF) of both values.
16: 1, 2, 4, 8, 16
24: 1, 2, 3, 4, 6, 8, 12, 24
The GCF of both values is 8.
Now divide, [tex]\frac{16}{24}[/tex] ÷ [tex]\frac{8}{8}[/tex] to get the final value of [tex]\frac{2}{3}[/tex].

What is (4/9)^2?
What is 4 over 9(as a fraction) to the power of 2?
Answers
Answer:
16/81
Step-by-step explanation:
To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.
Answer:
The answer is 16/81
Step-by-step explanation:
To evaluate this equation first find a understanding of what needs to be solved.
Here we see that we need to solve 4/9th to the power of 2.
to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.
To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.
In this case we need to do 4 x 4 and 9 x 9.
4 x 4 = 16
9 x 9 = 81
The 4 x 4 solution remains as the numerator
The 9 x 9 solution remains as the denominator
After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.
The correct answer is 16/81 have a great day :)
Veronica lives on a straight road that goes east and west. She starts from a point 5.1 miles west of her home and drives a certain distance to the store. The store is more than 3 1/2 miles east of her home. Let d represent the distance Veronica drove. Which inequality represents this situation?
Answers
Its C because 3 1/2 is grater than -5.1 because it is negative
The inequality is −5.1 + d > 3 1/2 which represents the situation, where d represents the distance Veronica drove.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Veronica lives on a straight road that goes east and west.
Let d represents the distance Veronica drove.
She started from a point 5.1 miles west of her home and drives a certain distance to the store.
So, she drives:
−5.1 + d
The store is more than 4 1/2 miles east of her home.
Therefore, the inequality that represents the situation is as follows:
−5.1 + d > 3 1/2
Hence, the correct answer would be an option (C).

Answers
refer to picture for steps
Let's verify all the options to the question. Clue given: x = 2, y = 4
Option A:
(x² + 8) ÷ y - 2
=> (2² + 8) ÷ 4 - 2
=> (4 + 8) ÷ 4 - 2
=> 12 ÷ 4 - 2
=> 3 - 2
=> 1 ≠ 6
This answer does not equal 6.
Option B:
(x² + 8) ÷ (y - 2)
=> (2² + 8) ÷ (4 - 2)
=> (4 + 8) ÷ (4 - 2)
=> 12 ÷ 2
=> 6 = 6
This answer is correct as 6 = 6.
Option C:
x² + 8 ÷ (y - 2)
=> 2² + 8 ÷ (4 - 2)
=> 4 + 8 ÷ 2
=> 4 + 4
=> 8 ≠ 6
This answer does not equal 6.
Option D:
x² + 8 ÷ y - 2
=> 4 + 8 ÷ 4 - 2
=> 4 + 2 - 2
=> 4 ≠ 6
This answer does not equal 6.
So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.
