Bicycles are often on sale in September. The regular price of one bicycle is $181.95. With a 20% discount, what is the sale price of the bicycle? Round to the nearest cent(hundredths).
Answers
Answer:
sale price = $145.56
Step-by-step explanation:
The regular price of one bicycle is $181.95
20% discount
sale price = original price - ( % discount x original price )
sale price = $181.95 - (0.20 * $181.95)
sale price = $181.95 - $36.39
sale price = $145.56

Answers
Answer:
15.2971ftStep-by-step explanation:
The question lacks appropriate diagram. Find the diagram in the attachment.
The triangle is a right angles triangle and the unknown side is the hypotenuse which is the longest side of a triangle and the other two sides are the opposite and the adjacent
Using the Pythagoras theorem to find the length of the hypotenuse, we will have;
hyp²= opp²+adj²
hyp²= 15²+3²
hyp²= 225+9
hyp²= 234
hyp = √234
hyp = 15.2971
Hence the length of the unknown side is 15.2971ft

Step-by-step explanation:
Converting it to decimal makes it easier to work with. It might make be an extra step, but in the long run of the problem it helps to make calculations accurate and easier to solve by working with simpler numbers. Converting to decimal form makes the number more precise for square roots, which are usually not whole numbers.

c: 10/3, 3 1/3, 3.3 repeating
b: 20/3, 6 2/3, 6.6 repeating
c: 8/15
d: 1
(a) Area of rectangle = 1.67 squares in
(b) Area of rectangle = 3.33 squares in
(c) Area of rectangle = 6.67 squares in
(d) Area of rectangle = 0.53 squares in
(e) Area of rectangle = 1 squares in
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
(a) Length of rectangle = 5 in and
Width of rectangle = 1/3 in
Area of rectangle = 5 × 1/3 = 5/3 = 1.67 square in
(b) Length of rectangle = 5/2 in and
Width of rectangle = 4/3 in
Area of rectangle = 5/2 × 4/3 = 20/6 = 3.33 square in
(c) Length of rectangle = 5 in and
Width of rectangle = 4/3 in
Area of rectangle = 5 × 4/3 = 20/3 = 6.67 square in
(d) Length of rectangle = 2/5 in and
Width of rectangle = 4/3 in
Area of rectangle = 2/5 × 4/3 = 8/15 = 0.53 square in
(e) Length of rectangle = 7/6 in and
Width of rectangle = 6/7 in
Area of rectangle = 7/6 × 6/7 = 42/42 = 1 square in

A chord is 15 cm long. It is 9 cm from the center of the circle. What is the radius of the circle?
Answers
Answer:
11.72cmStep-by-step explanation:
Given a chord of distance of 15cm, if it is 9cm from the center of a circle, this means that the 9cm length will be projecting from the centre of the circle perpendicular to the chord and passing through its centre.
Since the radius of a circle is a line that is drawn from the centre of a circle to ts circumference, the set up will form a right angles triangle within the circle with the hypotenuse as the radius and the other two sides as the opposite and adjacent respectively. Using the Pythagoras theorem to get the length of the radius (hypotenuse);
hyp² = opp² + adj²
Let the opposite be the 9cm length
Adjacent will be half of the chord length = 15/2 = 7.5cm
Substituting this values into the formula we will have;
hyp² = 9² + 7.5²
hyp² = 81+56.25
hyp² = 137.25
hyp² = √137.25
hyp = 11.72
Hence the radius of the circle is approximately 11.72 cm long
Four friends want to take a vacation together, so each one gets a part-time job. Each person has 8 weeks to save $720 for the vacation. Analyze the four individual plans below and decide which of the four people will reach his or her goal of saving $720 for vacation.
Friend A: Works 13 hours per week at $6.95 per hour.
Friend B: Works 15 hours per week at $5.85 per hour.
Friend C: Works 18 hours per week at $5.25 per hour.
Friend D: Works 11 hours per week at $7.80 per hour.
Answers
Answer:
The correct answer is option A. A and C

Find the angle between the vectors a = (4, 2, -4) and b = (4, -3, 2).
SOLUTION Since
lal = 42 + 22 + (-4)2 =
and
[b] = V 42 + (-3)2 + 22 = V 29
and since
a. b = (4)( 14 ) + (2)(-3) + (-4)(2 )
we have from this corollary
COS = a.b |а|
|Ь| | 89 So the angle between a and b is as follows. (Round your final answer to two decimal places.) 0 = cos-10 29 89 x rad
Answers
Answer:
86.45°Step-by-step explanation:
Given two vectors a = (4, 2, -4) and b = (4, -3, 2), the formula to be used to calculate the angles between both vectors is as expressed below;
[tex]a.b = |a||b| cos \theta[/tex] where [tex]\theta[/tex] is the angle between both vectors
a.b = (4, 2, -4). (4, -3, 2)
a.b = 4(4)+2(-3)+2(-4)
a.b = 16-6-8
a.b = 16-14
a.b = 2
Given |r| = √x²+y²+z²
|a| = √4²+2²+(-4)²
|a| = √16+4+16
|a| = √36
|a| = 6
Similarly;
|b| = √4²+(-3)²+2²
|b| = √16+9+4
|b| = √29
Substituting the parameters gotten into the formula to get the angle between the two vectors a and b we will have;
[tex]a.b = |a||b| cos \theta\\2 = 6*\sqrt{29} \ cos \theta\\ cos\theta = \dfrac{2}{6\sqrt{29} } \\cos\theta = \dfrac{1}{3\sqrt{29} }\\ cos\theta = 0.0619\\\theta = cos ^{-1}0.0619\\ \theta = 86.45^0 (to \ 2dp)[/tex]
Hence the angle between vectors a and b is 86.45°

Show that the set of solutions of a second-order linear homogeneous differential equation is linearly independent.
{eax, xeax}, a ≠ b
Find the Wronskian for the set of solutions.
{eax, xeax}, a ≠ b
Answers
Answer:
The set of solutions are linearly independent because the wronskian is
e^(2ax) ≠ 0
Step-by-step explanation:
To show that the set of solutions {e^(ax), xe^(ax)} are linearly independent, we find the Wronskian of the set of solutions.
Wronskian of y1 and y2 is given as:
W(y1, y2) = y1y2' - y1'y2
y1 = e^(ax)
y1' = ae^(ax)
y2 = xe^(ax)
y2' = axe^(ax) + e^(ax)
W(y1, y2) = e^(ax)[axe^(ax) + e^(ax)] - ae^(ax).xe^(ax)
= (ax + 1)e^(2ax) - axe^(2ax)
= e^(2ax)
The wronskian of the given set of solutions is e^(2ax), which is not zero.
Because it is not zero, the set of solutions are linearly independent.

Answer:
D
Step-by-step explanation:
First, let's define each of the terms.
Scalene refers to triangles whose three sides and three angles all have different measures.
Isosceles refers to triangles who has two equivalent angles and sides.
Right triangles are triangles with one right angle.
So we know that the triangle has one 90 degrees and 2 45 degree angles.
In other words, this is an isosceles triangle.
And since it also contains a 90 degree angle, it means that the triangle is an isosceles right.
The answer is D

Complete Question
CoStar would like to test if the vacancy rate for "warehouse" stores is more than 8%. A type 1 error would occur if CoStar concludes that the vacancy rate was
A: not equal to 8% when, in reality, the proportion was equal to 8%
B: 8% or less when, in reality, the proportion was more than 8%
C: equal to 8% when, in reality, the proportion was 8% or less
D: more than 8% when, in reality, the proportion was 8% or less
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
CoStar would like to test if the vacancy rate for "warehouse" stores is more than 8%.
Hence
The null hypothesis is [tex]H_o : p \le 0.08[/tex]
The alternative hypothesis is [tex]H_a : p> 0.08[/tex]
Generally type 1 error occurs when null hypothesis is rejected while it is true
So Type I error would occur if CoStar concludes that the vacancy rate was more than 8% when, in reality, the proportion was 8% or less
