Answer:
The mass of the Blue whale is 200 times the mass of the cow
Step-by-step explanation:
Given
Mass of Cow = 9 * 10² kg
Mass of Blue Whale = 1.8 * 10⁵ kg
Required
Determine the relationship between both weights
Represent the mass of the cow with C and the mass of the whale with B
Divide the bigger weight by the smaller weight
Multiply both sides by C
<em>From the expression above, it can be concluded that the mass of the Blue whale is 200 times the mass of the cow</em>
The function representing the number of ounces is:
2x - 3
Now, we are given the number of ounces = 7
Therefore:
2x - 3 = 7
We will solve this equation for x as follows:
2x-3 = 7
2x = 7 + 3
2x = 10
x = 5
Therefore, the number line representing this function will be the line having a solution ending at 5 (5 is included).
Therefore, the correct choice would be line B
We are given the function –2x – 4 + 5x = 8 and is asked in the problem to solve for the variable x in the function. In this case, we can first group the like terms and put them in their corresponding sides:
-2x + 5x =8+4
Then, do the necessary operations.
3x = 12
x = 4.
The variable x has a value of 4.
Answer:
5
Step-by-step explanation:
He can buy 5 boxes of light bulbs..
20 x 5= 100
He only has 120 to spend - the shipping = 110
He can't get another box of lightbulbs. Therefor he can only buy 5!
A sample statistic , such as x bar, that estimates the value of the corresponding population parameter is known as a control chart.
