Answer:
24%
Step-by-step explanation:
Q: Maya has 200 songs on her mobile device. Of these songs, 48 are jazz songs. What percent of Maya's songs are jazz songs?
To find the percentage of something, we can take the number that we want to find the percentage for divided by the total number of items.
In this problem, the number that we want to find the percentage for are the jazz songs, which is 48.
The total number of items is 200 songs.
Therefore, we can divide the number of jazz songs by the total number of songs in order to find the percentage of Maya's jazz songs.
# jazz songs/total # songs 48/200 = 0.24To convert a decimal to a percentage, we can move the decimal point two places to the right (aka multiply by 100).
0.24 → 24%24% of Maya's songs are jazz songs.

29 is the distance between the points (-30, -10) and (-30, 19) in the xy-plane.
Step-by-step explanation:
I've answered the question written, not the one in the picture.
You can either use the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex], or do Y2-Y1 (since the x-value is the same).

Answer:
The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.

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).

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

To measure the width of a river, you plant a stake on one side of the river, directly across from a boulder.
You then walk 100 meters to the right of the stake and measure a 79° angle between the stake and the
boulder. What is the width w of the river? Round your answer to the nearest meter.
Mattraimale

100 m
PUR
m
Answer:
514 m = width of the river to the nearest meter
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these types of problems are easy.
You have a right triangle where the 100 m is the adjacent side to the 79° angle. You are looking for the side opposite the 79° angle. So, you need to use the tan function which is defined as opposite side/adjacent side
Let x = the length of the opposite side (width of river)
Tan 79 = x/100
100 tan 79 = x
x = 514 m = width of the river to the nearest meter
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]
Hence, the width of the river is 514.455 meters.

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
