1. Jamal, Rick, and Maria ran for sixth-grade class president. The election results are shown:
Jamal 60 votes
Rick
50 votes
Maria 40 votes
What is the ratio, in simplest form, of the number of votes Rick received to the number of votes
Jamal received?
The ratio of votes Rick received to the votes Jamal received, in simplest form, is 5:6. This was calculated by dividing Rick's 50 votes by Jamal's 60 votes and then reducing the resulting fraction.
Explanation:The question asks for the ratio of the number of votes Rick received to the number of votes Jamal received in a sixth-grade class president election. To find this ratio, we simply divide the number of votes each candidate received. Rick received 50 votes, and Jamal received 60 votes.
Now we divide Rick's votes by Jamal's votes: 50 ÷ 60. When we reduce this fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 10 in this case. So, the simplified ratio is 5:6. This means that for every 6 votes Jamal received, Rick received 5 votes.

Alexandra wants to buy a CD for $400 that earns 4% APR and is compounded
quarterly for 3 years. She will be taxed on 20% of the interest that she earns.
What is the total amount of interest Alexandra will earn, after taxes?
O A. $40.58
O B. $12.99
O c. $16.24
O D. $50.73
SUBMIT
The total amount of interest Alexandra will earn, after taxes is, $51.05.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, To calculate the total amount of interest Alexandra will earn, we first need to calculate the annual interest rate.
Since the APR is 4%,
Hence, we can calculate the quarterly interest rate by dividing 4 by 4 = 1%.
Next, we need to calculate the number of quarters in 3 years which is,
⇒ 3 x 4 = 12 quarters.
Now, Using the formula for compound interest, we can calculate the balance of Alexandra's account at the end of the 3-year period:
Balance = Principal (1 + (rate/n))ⁿˣ
where, P = Principal = $400
r = Annual interest rate = 4%
n = Number of times interest is compounded per year = 4 (quarterly)
x = Number of years = 3
Plugging in the values,
Balance = $400 (1 + (0.04/4))¹²
= $463.81
Next, we need to calculate the total amount of interest Alexandra earned, which is the difference between the balance and the principal:
Total interest earned = $463.81 - $400 = $63.81
Since Alexandra will be taxed on 20% of the interest, we need to calculate the amount of tax she will pay:
Tax = 20% of $63.81
= $12.76
Finally, we can calculate the total amount of interest Alexandra will earn after taxes:
Total interest earned after taxes = $63.81 - $12.76 = $51.05
Therefore, the correct answer is, $51.05.

The sum of 3 times a number and 9 equals 4 use the variable b for the unknown number write in an equation
Answer: b= -5 over 3
Step-by-step explanation:
create the equation 3b + 9 = 4
subtract 9 from each side to isolate the variable
we are left with 3b = -5
to further isolate the variable divide by 3
3b/3 = -5/3
3b divided by 3 is b, which is equal to -5 divided by 3; -5/3
b = -5/3 is your answer
Final answer:
To represent the statement 'The sum of 3 times a number and 9 equals 4' with b as the unknown number, the equation is 3b + 9 = 4. Solving for b gives us b = -5/3.
Explanation:
The question asks to write an equation with the variable b as the unknown number, where three times this number plus nine is equal to four. To write the equation we need to translate the sentence into mathematical terms: three times a number can be expressed as 3b, and 'the sum of 3 times a number and 9' can be written as 3b + 9. Therefore, the complete equation that represents the sum of 3 times a number and 9 equals 4 is 3b + 9 = 4.
To solve for b, we can carry out some simple math by subtracting 9 from both sides to get 3b = -5, and then dividing both sides by 3 to find the value of b, which would be b = -5/3.

D. The x- and y-values are negative,
PLZ HELP!!
Answer:
the answer is C. they are both positive.
Step-by-step explanation:
This is because over the y axis is the first quadrant which is always positive.
Final answer:
Upon reflection over the y-axis, the x-values of the vertices become negative, and the y-values remain positive; hence, option A is correct.
Explanation:
The question asks what is true about the vertices of a triangle located in the first quadrant of the coordinate plane when it is reflected over the y-axis. A reflection over the y-axis in the Cartesian coordinate system would mean that for any point (x, y) on the triangle, the x-coordinate would change its algebraic sign while the y-coordinate would remain the same. This is due to the properties of reflection over an axis where coordinates perpendicular to the axis of reflection change signs, and those parallel remain unchanged.
The correct answer here would be A. The x-values are negative because they are reflected across the y-axis, changing their signs from positive to negative. However, the y-values would remain positive since the triangle is still located in the quadrant above the x-axis, where y-values are positive.
solve for 3 tanx = sqrt3 tanx
Answer:
Correct Answer is D.
Step-by-step explanation:
Solve for tanx,
3tan2x−√3tanx=0
√3tanx(√3tanx−1)=0
Thus tanx=0,tanx=1√3
For tan x =0, the principal solution is x=0,π
For tanx=1√3, the principal solution would be x=π/6,7π/6
The solutions are x = nπ, where n is any integer.
We are given the trigonometric equation 3 tan(x) = √3 tan(x). To solve for x:
Subtract √3 tan(x) from both sides of the equation to get all terms involving tan(x) on one side: Factor out tan(x): Set each factor to zero and solve for x: tan(x) = 0 when x is an integer multiple of π:x = nπ where n is any integer.
This represents all angles where the tangent is zero.

Given: m LHE =84°
Find: m∠EYL.
Answer: [tex]m\angle EYL=96\°[/tex]
Step-by-step explanation:
For this exercise you need to use the formula for calculate the measure of the angle formed by two tangents intersecting outside of a circle. This is:
[tex]Angle\ formed \ by\ two\ tangents = \frac{1}{2}(Difference\ of\ Intercepted\ Arcs)[/tex]
According to the information given in the exercise, you know that:
[tex]Angle\ formed \ by\ two\ tangents = m\angle EYL\\\\Difference\ of\ Intercepted\ Arcs=m LVE-mLHE[/tex]
Since there are 360 degrees in a circle, you can determine that:
[tex]mLVE=360\°-mLHE\\\\mLVE=360\°-84\°\\\\mLVE=276\°[/tex]
Therefore, knowing these values, you can substitute them into the formula given above and the evaluate, in order to find the measure of the angle EYL. This is:
[tex]m\angle EYL=\frac{1}{2}(276\°-84\°) \\\\m\angle EYL=96\°[/tex]
A cyclist rode at constant speed of 23 mph for 4 hours. Then, she decreased her rate of speed to 16 mph for 5 hours. How far did the cyclist ride in 9 hours?
The cyclist rode a total of 172 miles in 9 hours, covering 92 miles at 23 mph for 4 hours and 80 miles at 16 mph for 5 hours.
Explanation:To find out how far the cyclist rode in 9 hours, we need to calculate the distance covered at each speed and then add those distances together. The cyclist rode at a constant speed of 23 mph for 4 hours and then at a speed of 16 mph for 5 hours.
First, we calculate the distance at 23 mph:
Distance = Speed × Time
Distance at 23 mph = 23 mph × 4 hours = 92 miles
Next, we calculate the distance at 16 mph:
Distance at 16 mph = 16 mph × 5 hours = 80 miles
Now, we add the distances together to get the total distance:
Total Distance = Distance at 23 mph + Distance at 16 mph
Total Distance = 92 miles + 80 miles = 172 miles
Therefore, the cyclist rode a total of 172 miles in 9 hours.

Lorenzo has a package that weighs 2 pounds.
He wants to check the weight of the package on a scale, but he only has weights that are measured in ounces
Drag the weights into the box that will balance the scale. Each weight can be used once or not at all,
4 oz
10 OZ
12 oz
16 OZ
30 oz
Weights Needed to Balance Scale
Answer:
16 oz, 12 oz, 4 oz
Step-by-step explanation:
Since 1 pound is equal to 16 ounces, and you can only use each weight once or not at all, you can determine how much is needed by simply adding.
2 pounds is equal to 32 ounces.
To achieve 32 ounces, you can use a 16 ounce weight, which will then bring the scale to need 16 ounces.
After this you can youse a 12 ounce weight, which brings it down to 4 ounces.
The last weight needed is the 4 ounce weight which will then level out the balance scale.

Find the MEAN is this data set ?
And the ABSOLUTE DEVIATION ?
The mean of a dataset is the sum of the elements divided by how many elements are present in the data set.
The sum of the elements in this dataset is
[tex]93+95+102+91+104+93+95+98+97+92+102+96+92+104+100+98=1552[/tex]
And there are 16 elements, so the mean is
[tex]\mu = \dfrac{1552}{16}=97[/tex]
The absolute deviation is computed as follows:
For each term in the dataset, we consider its distance from the mean. In formulas, we compute [tex]|x_i-\mu|[/tex] for every element [tex]x_i[/tex] We take the average of all these terms: [tex]\frac{1}{n}\sum|x_i-\mu|[/tex]So, following the first point, the new dataset is
[tex]\{4, 2, 5, 6, 7, 4, 2, 1, 0, 5, 5, 1, 5, 7, 3, 1\}[/tex]
And the average of this dataset is
[tex]\dfrac{4+2+5+6+7+4+2+1+0+5+5+1+5+7+3+1}{16} = \dfrac{58}{16}=3.625[/tex]
