Answer:
Step-by-step explanation:
Amber coaches both sports for 7 hours each day
v = volleyball hours
s = soccerball hours
7 hours in total, in which soccerball is 1 hour more than volleyball:
v + s = 7
s = v + 1
plug in v + 1 for s
v + s = 7
v + (v + 1) = 7
simplify
v + v + 1 = 7
2v + 1 = 7
2v + 1 (-1) = 7 (-1)
2v = 6
2v/2 = 6/2
v = 6/2
v = 3
Plug in 3 for v for one of the equations.
s = v + 1
s = (3) + 1
s = 4
Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours becuase 4+3 equals 7
hope this help :DDDDD
The base of a parallelogram is 6ft more than the height. If the area of the parallelogram is 27ft^2, what are the measure of the base and the height?
The measure of the base and the height of the parallelogram are;
Height = 3 ft
Base = 9 ft
How to calculate the area of a parallelogram?The formula for the area of a parallelogram is expressed as;
Area = Base × Height
From the question, we are told that the base of the parallelogram is 6 ft more than the height. Thus;
Base = 6ft + h
If the area of the parallelogram is 27 ft^2, then the measures of the base and the height is calculated as;
27 ft² = ( 6 + h ) × h
27 = 6h + h²
h² + 6h - 27 = 0
h² + 9h - 3h - 27 = 0
h(h + 9) - 3(h + 9) = 0
(h + 9)(h - 3) = 0
h = -9 or 3
We will pick the positive one which is 3 and so;
height = 3ft
Base = 6 + 3
Base = 9ft

Values = [ 14, 10, 8, 19, 7.13] print the interger at index 2 of values and print the integer at index -2 of values, both on one line.
Therefore, the final code would be:values = [ 14, 10, 8, 19, 7.13] print(values[2], values[-2])This code would print the following output:8 19
What is meant by indices?Indices, also known as exponents or powers, are mathematical symbols that express the repeated multiplication of a number. These numbers show how many times the base number has been multiplied by itself. For example, the index of 2 in the formula 23 is 3, which indicates that 2 is multiplied by itself three times to provide the value 8. Indices are often written as little numbers to the right and above the base number, with the latter enclosed in parentheses or brackets. Indices are often used to indicate the size or quantity of a number in mathematical model, but they may also be used to represent the degree of a polynomial function or the order of a derivative in calculus.
How to solve?
To print the integer at index 2 of the values list, we can use the following code: print(values[2])
To print the integer at index -2 of the values list, we can use the following code: print(values[-2])
Here, the index -2 refers to the second-to-last element in the list, which is the integer 19.
Therefore, the final code would be:
values = [ 14, 10, 8, 19, 7.13]
print(values[2], values[-2])
This code would print the following output:

error analysis correct the error in the following equation explain the mistake 5x + 5(-2x - 12) = 130 5x + -10x - 60 = 130 =65x = 130 x = -2
Answer:
Step-by-step explanation:
The given error full solution is
5x+5(-2x-12)=130
5x+-10x-60=130
65x=130x=-2.
Correct answer is given as
5x+5(-2x-12)=130.
We solve this question using Bodmas rule. So first we remove the parenthesis.
5x+5(-2x-12)=130
5x+5(-2x)+5(-12)=130
5x-10x-60=130
-5x=130+60
-5x=190
dividing both side by by (-5). We, get
x=190/(-5)
x=-38
Hence, the correct answer is x=-5

10. 2g(-4) = 2
We are given the linear functions:
f(x) = 2x - 5 and
g(x) = |- 3x - 11|
Let us solve one by one:
5. f(3)
Substitute the value of x with 3 in f(x), we will get;
f(3) = 2 * 3 - 5 = 6 - 5 = 1
6. f(1) + g(2)
f(1) = 2 * 1 - 5 = 2 - 5 = -3
g(2) = |- 3 * 2 - 11| = |- 6 - 11| = 17
f(1) + g(2) = -3 + 17 = 14
7. g(0)
g(0) = |- 3 * 0 - 11| = | - 11| = 11
8. g(2) - f(0)
g(2) = |- 3 * 2 - 11| = |- 6 - 11| = 17
f(0) = 2 * 0 - 5 = 0 - 5 = -5
g(2) - f(0) = 17 - (-5) = 22
9. f(-1) - g(3)
f(-1) = 2 * -1 - 5 = -2 - 5 = -7
g(3) = |- 3 * 3 - 11| = |- 9 - 11| = 20
10. 2g(-4)
g(-4) = |- 3 * -4 - 11| = |12 - 11| = 1
2g(-4) = 2 * 1 = 2

7. g(0) = 11
8. g(2) - f(0) = 22

ABCD is a rhombus.
The coordinates of A are (5,11)
The equation of the diagonal DB is y = [tex]\frac{1}{3}[/tex] x + 5
The equation of the diagonal AC can be written in the form y = mx + c where m and c are integers.
Work out the value of m and the value of c.
Answer:
m = - 3 and c = 26
Step-by-step explanation:
• the diagonals of a rhombus are perpendicular bisectors of each other
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x + 5 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation of AC
to find c substitute A (5, 11 ) into the partial equation
11 = - 15 + c ⇒ c = 11 + 15 = 26
y = - 3x + 26 ← equation of diagonal AC
with m = - 3 and c = 26

Mariam ue 12 gallon of ga to drive 259. 2 mile in her car. Find the rate of change
The rate of change is 21.6 mpg.
The rate of change determines how one variable changes because of another variable. This rate value can be either positive or negative. Considering x as an independent variable and y as a dependent variable, the rate of change for these two variable is given by,
[tex]\text{rate of change}= \frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}[/tex]
From the given value, miles traveled is a dependent variable because it depends on the amount of gas. So the amount of gas is the independent variable.
Therefore, the rate of change is,
[tex]\begin{aligned}\text{rate of change}&=\frac{\Delta y}{\Delta x}\\&=\frac{\mathrm{259.2\;miles}}{1\mathrm{2\;gallons}}\\&=\mathrm{21.6\;mpg}\end{aligned}[/tex]

What is area ?A two-dimensional figure, form, or planar lamina's area is a measure of how much space it takes up in the plane. The area is simply the amount of cloth or other material with the specified thickness needed to build a model of the shape or the quantity of paint required to cover the shape's surface in a single layer, or "coat," of paint. It is the two-dimensional representation of a curve's length or a solid's volume, where length is a one-dimensional concept and volume is a closely related three-dimensional term.
There are a tonne of 2-D shapes all around us, including circles, triangles, squares, rectangles, parallelograms, and trapezoids. You are able to draw.

What is an equation?
Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also explores and solves Diophantine equations with integer coefficients. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.
The required equation of the line is
(y-4) = (0+6)/(4-8) (x-0)

The amount owed at the end of the 6 years duration is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

The half-life of sodium-24 is around 15 hours. If just 1/8 of the sodium-24 is left, it has been eliminated in 60 hours.
What is the decay and half-life law?The half-life is the amount of time needed for half of the initial population of radioactive atoms to decay. T1/2 = 0.693/λ is the equation that describes the connection between the half-life, T1, and the decay constant. The rate of radioactive atoms decaying at any given instant is precisely proportional to the quantity of atoms present at that time, as stated by the radioactive decay law.
dtd N ∝ N
dtd N = λ N
where, N is number of integrated nucleus present in the sample at any time t and λ is decay constant.
