The customer would pay $54.40 for the shoes
What is the dollar value of the initial discount of 20%?
The dollar worth of the general discount of 20% of the price of $80 is determined as 20% multiplied by the shoe price
dollar worth of initial discount=20%*$80
dollar worth of the initial discount=$16
the price after the initial discount=$80-$16
the price after the initial discount=$64
The fact the customer has a coupon to receive additional 15% off the sale price means the purchase price for the customer is as computed thus:
final sale price=$64*(1-15%)
final sale price=$54.40

Juan and Joe start walking around a track at the
same time and at the same place. It takes Joe 8
minutes to walk around the track, and it takes Juan
10 minutes. After how many minutes will they reach
the starting point at the same time?
In linear equation , 40 is the number of minutes until they meet again at the starting line.
What is linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Juan walks 1/8 of a lap in one minute
joe walks 1/10 of a lap in one minute
The LCM of 8 and 10 = 40 = the number of minutes until they meet again at the starting line
In that time Juan walks (1/8) * 40 = 5 laps
And Juan walks (1/10)*40 = 4 laps

the 2nd and 5th terms of a gp are 1/18 and 4/243 respectively. Find
Answer:
Step-by-step explanation:
The third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.
We are given that:
2nd term of geometric progression = 1 / 18
5th term = 4 / 243
Now, we can also write it as:
2nd term = a r ( where r is the common ratio and a is the initial term.)
a r = 1 / 18
5th term = a r⁴
a r⁴ = 4 / 243
Now divide 5th term by 2nd term, we get that:
a r⁴ / a r = ( 4 / 243 ) / ( 1 / 18 )
r³ = 72 / 243
r³ = 8 / 27
r = ∛ (8 / 27)
r = 2 / 3
3rd term = a r²
a r² = a r × r
= 1 / 18 × 2 / 3
3rd term = 1 / 27
Therefore, the third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.

If the measure of angle is 3pi/4 , which statements are true?
If the measure about an angle is 3pi/4, the sentences are:
sinθ = sin135 = √2/2cosθ = cos135 = √2/2The correct option are A , D.
What is a trigonometric function?a function of an arc or angle represented most simply in terms of the ratios of pairs of sides of a right-angled triangle (such as the sine, cosine, tangent, cotangent, secant, or cosecant). also known as a circular function.
Why do we utilize trigonometric functions?Trigonometry is used to set directions such as north, south, east, and west; it tells you which direction to go using the compass to get on a straight path. It is used in trace to locate a location. It is also used to determine the distance between the shore and a point in the water.
According to the given data:Investigation trigonometric function:
θ = 3π/4
= 3/4 * 180
= 135
tanθ = sin135/cos135
= -1
sinθ = sin135 = √2/2
cosθ = cos135 = √2/2
The reference angle for stuff in Q2 is 180 - theta = 180 - 135 = 45 degrees.

The measures of the angles are x = 40, x = 110 and y = 70
What are angles?Angles are formed when two or more lines intersect
How to calculate the values of x, y and z?The figure represents the given parameters
On the figure, we have the following highlights
Angle 3 and angle y are corresponding angles.
Corresponding angles are congruent
So, we have
y = Angle 3
From the figure
Angle 3 = 70
So, we have
y = 70
The angle on a straight line is 180 degrees
So, we have
x + y = 180
This gives
x + 70 = 180
Evaluate the like terms
x = 110
The triangle is an isosceles triangle.
So, we have
y = Angle 2
This means that
Angle 2 = 70
The sum of angles in a triangle is 180
So, we have
z + y + Angle 2 = 180
This gives
z + 70 + 70 = 180
Evaluate
z = 40
Hence, the measures of the angles are x = 40, x = 110 and y = 70

Write an equation of a parabola in vertex form. Vertex (0,-3) and passes through (-8,5)
The equation of the parabola that has vertex (0, -3) and also passes through the point (-8,5) is y = -1(x - 0)² - 3.
The vertex form of the equation of a parabola is:
y = a(x-h)² + k
where the vertex = (h, k)
The given vertex, (h, k) = (0, -3)
The line passes through the (-8, 5)
x = -8, y = 5
Substitute x = -8, y = 5, h = 0, y = -3 into the equation to solve for a
y = a(x - h)² + k
5 = a(-8-0)² + (-3)
5 = a(-8)² - 3
-8a = 5+3
-8a = 8
a = 8/-8
a = -1
Substitute a = -1, h = 0, k = -3 into y = a(x - h)² + k

Answer:
B
Step-by-step explanation:
None of the provided options are irrational. Irrational numbers are those which cannot be expressed as the ratio of two integers. In other words, if represented in decimal form, they would continue indefinitely after the decimal point, such as the value of π. This also means, by definition, they cannot be both irrational and an integer.
They are all real numbers as they can represent a distance along a line (they could all be plotted on a number line or graph, for instance).
Only 0 and 4 out of the provided options are integers (whole numbers). As mentioned above, all integers are rational by definition.

The length of a rectangle parking area is three times the width.The perimeter is 280 yd.Find the length and width of the parking are.
Answer:
length = 105 yd
width = 35 yd
Step-by-step explanation:
Let L = length and W = width.
L = 3W
perimeter = 2(L + W)
280 =2(L + W)
L = 3W
We have a system of 2 equations. Let's use the substitution method to solve it. Substitute 3W for L in the first equation.
280 = 2(3W + W)
140 = 4W
W = 35
L = 3W = 3(35) = 105
length = 105 yd
width = 35 yd

The equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.
How do we find the equation of a line when two lines are parallel?We can infer that the two lines are parallel because they are distinct and share the same slopes. We can determine whether any two lines are parallel using this characteristic.Then we determine the equation of the line by point-slope form.A point on the line and the slope of the line are required in the point-slope version of the equation of a line. The line's slope is m, and the referred point on the line is (x₁,y₁).Given line: y = 4x - 7
Slope of line m₁ = 4
Two lines are parallel lines when the slopes of the lines are the same.
so, m₁ = m₂
m₂ = 4
Now, the equation of a line with slope 4 and passing through the point (4,1) is:
⇒ y - y₁ = m (x - x₁)
⇒ y - 1 = 4(x - 4)
⇒ y - 1 = 4x -16
⇒ y = 4x - 15
Hence the equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.

The probability the at least of the people selected from 5 is vaccinated is 0.997.
What is meant by the binomial distribution?The binomial distribution is a statistical probability distribution that summarizes the likelihood of a value taking one of two independent values under the specific set of assumptions or assumptions.
The likelihood that at least one person has been vaccinated = 1 - the likelihood that nobody has been vaccinated. In a large population, the probability of a randomly selected person NOT being vaccinated is 1 - 0.53 = 0.47.Because the five randomly chosen people are independent, the probability that they're all unvaccinated is (0.47)⁵,
The probability that at least one among them 5 has been vaccinated is;

Draw a rotation of segment CD 189 degrees around point D.
Rotation of a point through 189° about the origin When a point C(h, k) is rotated through 180° in either an anticlockwise or clockwise direction about the origin O, it takes the new position D(-h, -k).
The rotation formula will give us the precise location of a point after a finite degree of rotation. The rotation formula is determined by the type of rotation applied to the point in relation to the origin. A geometric two-dimensional shape can undergo four major types of transformation.
The rotation formula describes how a point rotates with respect to the origin. The rotation formula is used to determine the position of a point after it has been rotated. A rotation is a circular motion around a specific axis or point of rotation. In general, rotation can be done in two ways: clockwise and anti-clockwise or counter-clockwise.
