If gas costs $2.85 per gallon, how many whole gallons of gas could you buy with $30.00?
Answer:
11
Step-by-step explanation:
We can buy 10 gallons of gas with $30, whose unit price is $2.85.
What is unit rate?The rate calculated for one quantity of something is called unit rates.
Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.
Let the x gallons cost $30.00
Therefore,
2.85x = 30
x = 30 / 2.85
x = 10.52
x ≈ 10
Hence, we can buy 10 gallons of the gas from $30.

Dale just bought 9 bags of 13 cookies each. He already had 6 cookies in a jar. How many cookies does Dale have now?
Answer:
123
Step-by-step explanation:
1 bag = 13 cookies
9 bags x 13 cookies = 117 cookies
117 cookies + 6 cookies that he already has = 123 cookies
Dale have 123 cookies in total.
Answer:
123 cookies.
Step-by-step explanation:
Multiply the amount of bags of cookies he bought, and the amount of cookies in each back to find out the amount of cookies he bought all together.
9 x 13 = 117
He already had six cookies saved. Add that the amount he had bought
117 + 6 = 123
Dale has 123 cookies in total.

Find the slope
Answer:
slope = 4/11
Step-by-step explanation:
To find the slope, use delta y/ delta x
(4,6) (-7,2)
(2-6)/(-7-4)
(-4)/(-11)
slope = 4/11
Let m = slope
m = difference of y-values divided by the difference of x-values.
m = (2 - 6)/(-7 - 4)
m = -4/-11
m = 4/11

17. A line passes through the points (0,5) and (3, 11). Which of the following is the value of y when this line passes through x = 10? (1) 16 (3) 21 (2) 19 (4) 25
Answer:
(4) 25
Step-by-step explanation:
First, find the slope using rise over run:
(y2 - y1) / (x2 - x1)
Plug in the points:
(11 - 5) / (3 - 0)
6 / 3
= 2
The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:
y = mx + b
y = 2x + 5
Now, plug in 10 as x to find the value of y:
y = 2x + 5
y = 2(10) + 5
y = 20 + 5
y = 25
So, the correct answer is answer choice 4, 25.
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
A line passes through points (0,5) and (3, 11). Then the equation of the line is given as,
(y - 5) = [(11 - 5) / (3 - 0)](x - 0)
y = 2x + 5
If the value of the variable 'x' is 10, then the value of the variable 'y' is calculated as,
y = 2(10) + 5
y = 20 + 5
y = 25
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Given that log_{a}(3) = 0.477 and
log_{a}(5) = 0.699, evaluate log_{a}(0.6) .
*The answer is -0.222 but I'm not sure how to do the steps.
Given:
[tex]\log_{a}(3) = 0.477,\log_{a}(5) = 0.699[/tex]
To find:
The value of [tex]\log_{a}(0.6)[/tex].
Solution:
We need to find the value of:
[tex]\log_{a}(0.6)[/tex]
It can be written as
[tex]\log_{a}(0.6)=\log_a\left(\dfrac{6}{10}\right)[/tex]
[tex]\log_{a}(0.6)=\log_a\left(\dfrac{3}{5}\right)[/tex]
By using the property of logarithm, we get
[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex] [tex][\because \log \dfrac{a}{b}=\log a-\log b][/tex]
[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]
On substituting the given values, we get
[tex]\log_{a}(0.6)=0.477-0.699[/tex]
[tex]\log_{a}(0.6)=-0.222[/tex]
Therefore, the values of [tex]\log_a(0.6)[/tex] is -0.222.

Answer:
the answer is c 1.2
Step-by-step explanation:
to calculate the iqr you have to do the following:
q3 - q1 = answer
4.5 - 3.3 = 1.2
The IQR(interquartile range) for the distribution of the song length is 1.2.
What is interquartile range(IQR)?Interquartile range gives information on the spread of the middle half of your distribution.
Mathematically, the interquartile range can be represented as follows:
IQR = Q₃ - Q₁
where
Q₃ = 4.5
Q₁ = 3.3
Therefore,
IQR = 4.5 - 3.3
IQR = 1.2
Therefore, the interquartile range is 1.2.
