The gas of your car is 40% full. There are 8 gallons of gas in a tank. What is the capacity of the gas tank?
Thanks in advance!
Step-by-step explanation:
Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
capacity of the gas tank = x gallons
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
Answer = 20 gallons
Parallelogram ABCD has vertices at A(2,-3), B(8,-6), Cl14,-3), and D(8,0)
IF THE FOLLOWING STATEMENTS ARE TRUE, WHAT KIND OF PARALLELOGRAM IS THIS
The lengths of two consecutive sides are equal.
The slopes of two consecutive sides are not opposite reciprocals.
A) rectangle
B) square
C)rhombus
D) not enough info
Answer:
The correct option is C.
Step-by-step explanation:
The vertices of ABCD are A(2,-3), B(8,-6), C(14,-3), and D(8,0).
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The length of sides are
[tex]AB=\sqrt{(8-2)^2+(-6+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]BC=\sqrt{(14-8)^2+(-3+6)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]CD=\sqrt{(8-14)^2+(0-3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]AD=\sqrt{(8-2)^2+(0+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
Since length of all sides are equation therefore the given parallelogram cannot be a rectangle.
Slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of AB is
[tex]m_1=\frac{-6-(-3)}{8-2}=\frac{-3}{6}=\frac{-1}{2}[/tex]
Slope of BC is
[tex]m_2=\frac{-3-(-6)}{14-8}=\frac{3}{6}=\frac{1}{2}[/tex]
Since the slopes of two consecutive sides are not opposite reciprocals, therefore the given parallelogram is a rhombus. Option C is correct.
What is the solution to the system of equations below?
y= -1/3x+6 and x = –6
(–6, 8)
(–6, 4)
(8, –6)
(4, –6)
Final answer:
The solution to the system of equations is (-6, 8), found by substituting x = -6 into the first equation and simplifying to find the value of y.
Explanation:
The solution to the system of equations y= -1/3x+6 and x = -6 can be found by substituting the value of x from the second equation into the first equation. Here's how it's done:
Substitute x into the first equation: y = -1/3(-6) + 6.
Simplify the equation: y = 2 + 6.
Add the numbers to find the value of y: y = 8.
Therefore, the solution to the system of equations is the point (-6, 8).
the value of square root -9 is not -3 because ___
Final answer:
The square root of -9 is not -3 but 3i, indicating the need for complex numbers to describe the square root of negative numbers, with 'i' denoting the imaginary unit.
Explanation:
The value of the square root of -9 is not -3 because the square root operation defined for real numbers does not apply to negative numbers in the same way. Instead, when dealing with the square root of a negative number, we enter the realm of complex numbers.
A complex number is a combination of a real part and an imaginary part. The square root of -1 is defined as i, the imaginary unit. Therefore, the square root of -9 is correctly expressed as 3i, not -3. This is a critical distinction because the result provides a basis for complex arithmetic, expanding the scope of mathematical operations into the complex plane.
Complex numbers and imaginary numbers are fundamental in various fields of science and engineering, particularly in situations involving quadratic equations with no real roots or in the analysis of electrical circuits. Recognizing the utility of the imaginary unit, i, allows for solving equations that otherwise would not have solutions within the set of real numbers.

there is a string of green and white lights strung around a mirror for every 6 green lights there are four white lights if there are 30 green lights how many white lights are there
Answer: There are 20 white lights.
Step-by-step explanation:
Given : There is a string of green and white lights strung around a mirror for every 6 green lights there are 4 white lights.
i.e. Ratio of green lights to white lights = 6:4
i.e.
[tex]\dfrac{\text{Number of green lights}}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \dfrac{30}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \text{Number of white lights}=\dfrac{4\times30}{6}=20[/tex]
Hence, there are 20 white lights.
Which of the following functions is graphed below?
Answer:
y = abs (x-5) -4
Step-by-step explanation:
We are shifting the absolute value function
f(x) = |x| to
g(x) = | x +h| + k
where h is a shift left if h > 0
right if h < 0
and k is a shift up if k> 0
down if k< 0
Since the graph is shifted down and to the right
k is <0 and h < 0
where k = -4 and h=-5

Answer:
y=[tex]6x+ \frac{1}{2}[/tex]
Step-by-step explanation:
m=6
yint=1/2
y=mx+b
when x=0 y=1/2
1/2=6(0)+b
b=1/2
y=[tex]6x+ \frac{1}{2}[/tex]
The equation of the line in slope-intercept form is y = 6x + 1/2, where the slope is 6 and the y-intercept is 1/2. The slope of 6 means that for every increase of 1 in the x-axis, the y-axis will increase by 6.
Explanation:The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.
Given that the slope is 6 and the y-intercept is 1/2, the equation of the line is y = 6x + 1/2.

A basketball is priced at $35.00. If it is on sale for 40% off, what is the final cost?
A basketball priced at $35.00 with a 40% discount would cost $21.00 after the discount.
Explanation:The final price of the basketball can be calculated by first identifying the amount being discounted from the original price. A 40% discount of a $35.00 basketball means you take 40% of 35. Here's how:
0.40 (40% converted to decimal) times $35.00 equals $14.00.
This $14.00 is the discount from the original price. Now, subtract this discount from the original price of the basketball to get the final price: $35.00 - $14.00 equals $21.00.
So, the final cost of the basketball after a 40% discount is $21.00.

the mean of the values in a data set is a. If each of the values in the data set were multiplied by 7, what would be the mean of the resulting data?
Answer:
Mean of resulting data = 7 times mean of original data=7a
Step-by-step explanation:
Given that all values in a data set are multiplied by 7. to find the mean of the new set.
Let {x1,x2....xn} be the original data set.
The mean of this data set a= [tex]\frac{x1+x2+...+xn}{n}[/tex]
Now multiply all values by 7
New data set
= {7x1, 7x2...7xn}
Sum of these = 7(x1+x2+..+xn) = 7 times sum of original data set
No of element = n for both the sets
Hence new mean = 7 * mean of original set.=7a
in other words, if the mean of the values in a data set is a. If each of the values in the data set were multiplied by 7, new mean would be 7a.

Simplify the given expression below (1+2i) times (5-3i)
Answer:
11 + 7i
Step-by-step explanation:
(1 + 2i)(5 - 3i)
= 1(5 - 3i) + 2i(5 - 3i)
= 5 - 3i + 10i - 6i^2
Note i^2 = -1 So we have:-
5 + 7i + 6
= 11 + 7i (answer).
The expression (1+2i) times (5-3i) simplifies to -1 + 7i by using the distributive property for multiplication over addition and remembering that i squared equals -1.
Explanation:The expression (1+2i) times (5-3i) is a function of two complex numbers. To simplify this, you would use the distributive property for multiplication over addition.
The first step is to distribute each component of the first number against each component of the second number. (1 * 5 + 2i * -3i) + (1 * -3i + 2i * 5)
Next, we perform the multiplications and simplify, bearing in mind that i squared is -1. This gives us (5 - 6) + (-3i + 10i)
So the simplified expression is -1 + 7i.
