Answer:
3.0pages
Step-by-step explanation:
If Tiffany type a page in an hour, then;;
1 page = 1 hour
To calculate the number of pages typed in 3 hours, we can express as;
x pages = 3 hours
Divide both expressions
1/x = 1/3

Ali swam 0.5 squared kilometers in January and 0.3 cubed kilometers in February. What is the total distance he swam for both months? 1.9 kilometers 0.277 kilometers 0.727 kilometers 0.8 kilometers
Answer:
d = 0.277 km
Step-by-step explanation:
Distance covered in January = 0.5² km
The distance covered in February = 0.3³ km
We need to find the total distance he swam for both months. It can be calculated by finding their sum. So,
[tex]d=0.5^2+0.3^3\\\\d=0.25+0.027\\\\d=0.277\ km[/tex]
So, he swam 0.277 km for both months. Hence, the correct option is (b).

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

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.

Consider the following pair of equations:
y = 3x + 3
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(-2, -3)
Step-by-step explanation:
We are given y = 3x + 3 and y = x - 1.
We can substitute y = x + 1 into the y value for y = 3x + 3, so
x - 1 = 3x + 3 Now, we just subtract x from both sides.
-1 = 2x + 3 We subtract 3 from both sides.
-4 = 2x
2x = -4 We divide both sides by 2
x = -2 Now we have our x value - (-2, y)
Let's substitute the x value into both of the equations given.
1st equation:
y = 3(-2) + 3
y = -6 + 3
y = -3
2nd equation:
y = (-2) - 1
y = -3
We now know that both equations give us the same y value when x = -2 is substituted, therefore our solution is:
(-2, -3)
The solution for the pair of equations is (-2,-3).
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
The pair of equations are
y = 3x + 3 ------- (1)
y = x − 1 -------- (2)
Substitute the equation 2 in equation 1, we get
⇒ [tex]x-1=3x+3[/tex]
⇒ [tex]3x-x=-1-3[/tex]
⇒ [tex]2x=-4[/tex]
⇒ [tex]x=-2[/tex]
Now substitute x in equation 2,
⇒ [tex]y=-2-1[/tex]
⇒ [tex]y=-3[/tex]
Hence we can conclude that the solution for the pair of equations is (-2,-3).

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
