NEED HELP RIGHT NOW PLZ!!!!!!!!!!!!Two candidates, Joe Smith and Maria Jones run for office in a local election. In all, 12,402 votes are cast and the ratio of votes for Joe Smith to Maria Jones was 4:5. How many votes did they each get?
Answer:
Joe 5512
Maria 6890
Step-by-step explanation:
Joe : Maria : total
4 5 9
We have a total of 12402
Divide this by 9
12402/9 =1378
Multiply each number by 1378
Joe : Maria : total
4*1378 5*1378 9*1378
5512 6890 12402
How many solutions does the system of equations below have?
y=3x+4
y+6x=3x
Answer:
x = -[tex]\frac{2}{3}[/tex]
y = 2
Step-by-step explanation:
The process of elimination is a method of solving a system of equations. One must first manipulate one of the equations such that one of the variables shared between the two equations has the inverse coefficient of the same variable in the other equation. Therefore, when one adds the equations, the variable cancels. One can solve for the variable using inverse operations, and then backsolve to find the value of the first variable.
When given the following system:
y = 3x + 4
y + 6x = 3x
Use inverse operations so that both equations are solve for one variable,
y = 3x + 4
y = -3x
Add the systems so that one of the variables (x) cancels, this process is called the process of elimination;
y = 3x + 4
y = -3x
_________
2y = 4
Inverse operations,
2y = 4
y = 2
Now backsolve, find the value of (x) by substituting the value of (y) into the equation:
y = -3x
2 = -3x
x = -[tex]\frac{2}{3}[/tex]

Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans to weigh a rock 20 times and then calculate the average of the 20 measurements to estimate her rock's true weight. A second student plans to weigh a rock 5 times and calculate the average of the 5 measurements to estimate his rock's true weight. Suppose the students construct a 95% confidence interval for the true weight of their rocks. Whose interval do you expect to be more precise (narrower)
Answer:
The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
[tex]M = z\frac{s}{\sqrt{n}}[/tex]
In which z is related to the confidence level, s to the standard deviation and n to the sample size.
The margin of error is inversely proportional to the square root of the sample size, which means that a larger sample will lead to a lower margin of error, that is, to a more precise interval.
In this question:
One student will use 5 measurements, other 20. The first student, with 20 measurements, will have the more precise interval due to the larger sample size.

Fine the area of a triangle with :base=7ft and height =5ft
Answer:
Step-by-step explanation:
7 x 5 = 35
35/2 = 17.5
[tex]17.5ft^{2}[/tex]
The area of the given triangle is 17.5 ft²
What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given a triangle with base=7ft and height =5ft
We know that area of a triangle = 1/2 × base × height
Therefore, the area of a triangle = 1/2 (7)(5) = 17.5 ft²
Hence, the area of the given triangle is 17.5 ft²

Find the circumference of the given circle.
Use 3.14 as an approximation of Pi.
Answer:
Step-by-step explanation:
circumference=2*pie*r
=2*3.14*7
=43.96 in.
========================================================
Work Shown:
C = 2*pi*r
C = 2*3.14*7
C = 43.96 inches is the approximate circumference, aka the distance around the circle.
Use more decimal digits in pi to get a more accurate circumference.
Which linear function has a y-intercept of -5?
Answer: Upper right corner (northeast corner)
x-3y = 15
===================================================
Explanation:
The y intercept always occurs when x = 0.
If we plug x = 0 into 2x+y = -10 (northwest corner), then we solve for y to get...
2x+y = -10
2(0)+y = -10
0+y = -10
y = -10
We see that the y intercept here is -10, but we want -5 instead. So we can rule this out.
In the northeast corner, plugging x = 0 leads to,
x-3y = 15
0-3y = 15
-3y = 15
y = 15/(-3)
y = -5
We get the correct y intercept we're after. So we can stop here.
If you plugged x = 0 into the equation of the southwest corner, you'll get y = 5 which is fairly close but not quite what we want. The southeast corner equation leads to a y intercept of y = 5 as well.
Answer:
x - 3y = 15
Step-by-step explanation:
x - 3y = 15
-3y = -x + 15
y = 1/3x - 5
-5 is the y-intercept.

Answer:
[tex]\frac{3x^3z^5}{5y}[/tex] ( [tex]\frac{20y^3}{x^2z^6}[/tex])
Step-by-step explanation:
When given the following equation,
[tex]\frac{3x^3z^5}{5y}[/tex] ÷ [tex]\frac{x^2z^6}{20y^3}[/tex]
The first step is to convert the equation into a form that can be solved, in essence dividing any number by a fraction is the same as multiplying that number by the reciprocal of the fraction. The reciprocal of a fraction is when one switches the position of the numerator and denominator, the numerator is the number on top of the fraction, and the denominator is the number underneath the fraction.
[tex]\frac{3x^3z^5}{5y}[/tex] ÷ [tex]\frac{x^2z^6}{20y^3}[/tex]
[tex]\frac{3x^3z^5}{5y}[/tex] * [tex]\frac{20y^3}{x^2z^6}[/tex]
Simplify, reduce the numbers that are found in common between the numerator and denominator,
[tex]\frac{3x^3z^5}{5y}[/tex] * [tex]\frac{20y^3}{x^2z^6}[/tex]
[tex]\frac{3x^3z^5*20y^3}{5y*x^2z^6}\\\\=\frac{3x*4y^2}{z}\\\\=\frac{12y^2x}{z}[/tex]
Rommel has 3 kilograms of potatoes and 4 kilogramsof onions. He plans to use 1.5 kilograms of potatoes and 880 grams of onions fora recipe. How many total kilograms of the produce will not be used?
Answer:
4.62 KG
Step-by-step explanation:
1000 grams = 1kg
3kg = 3000g
4 kg = 4000g
1.5 = 1500g
left over potatoes = 3000 - 1500 = 1500 g or 1.5kg
left over onions = 4000 - 880 = 3120 = 3.12kg
total kilos not used = 1.5 + 3.12 = 4.62

Fast problem! Please help
Answer:
D. 122 degrees
Step-by-step explanation:
The angle next to the 133 degree angle is equal to 47 degrees because they are linear pairs. (Linear pairs will always add up to 180 degrees).
The angle below the 75 degree angle is equal to 75 degrees because they are vertical angles. (Vertical angles will always be equal to each other).
Then by using the Triangle Exterior Angle Theorem. Your missing angle is equal to 47 degrees + 75 degrees = 122 degrees.

find all the possible of x for which of the below is true:

Answer:
x = [tex]\frac{1}{2}[/tex] , x = 1
Step-by-step explanation:
Given
[tex]\frac{2x}{x+3}[/tex] + [tex]\frac{3}{x-3}[/tex] = [tex]\frac{8}{x^2-9}[/tex] ← denominator is a difference of squares
[tex]\frac{2x}{x+3}[/tex] + [tex]\frac{3}{x-3}[/tex] = [tex]\frac{8}{(x+3)(x-3)}[/tex]
Multiply through by (x + 3)(x - 3) to clear the fractions
2x(x - 3) + 3(x + 3) = 8 ← distribute left side and simplify
2x² - 6x + 3x + 9 = 8
2x² - 3x + 9 = 8 ( subtract 8 from both sides )
2x² - 3x + 1 = 0 ← in standard form
(2x - 1)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
x - 1 = 0 ⇒ x = 1

Question 16 of 20
To the nearest hundredth, what is the circumference of a circle with a radius
of 7 units?
A. 43.98 units
B. 21.99 units
C. 35.75 units
D. 153.94 units
Answer:
43.98
Step-by-step explanation:
The circumference of a circle with a radius of 7 units is approximately 43.98 units, which corresponds to option A.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
Given that the radius of the circle is 7 units, we can substitute this value into the formula:
To find the circumference of a circle, we can use the formula C = 2πr, where C represents the circumference and r represents the radius.
C = 2π(7) = 14π
Use the approximation π ≈ 3.14:
C ≈ 14(3.14) = 43.96
Rounding this value to the nearest hundredth, we get approximately 43.98 units.
Therefore, the circumference of a circle with a radius of 7 units is approximately 43.98 units.
