Here is a circle with center H and some line segments and curves joining points on the circle. Identify ONE example of each of the following.
a. Diameter
__________
b. Radius
_________
(Be sure that your book includes your written reasoning.)
Answers
Answer:A diameter is a chord that runs through the center point of the circle. It is the longest possible chord of any circle
Step-by-step explanation:The Radius is the distance from the center outwards.
The examples are,
a. Diameter: DG
b. Radius: AH, EH, DH, GH
What is meant by Diameter?Diameter: straight line passing one side to another side through the center of a circle or sphere is known as diameter.the line DG joins 2 points on the circle from one side to another passing through the center of the circle.Therefore, the DG segment is an example of a diameter.Radius: a line segment extending from the center of a circle or sphere to the circumference is known as a radius.The lines HA, HE, HD, and HG, extend from the center of the circle to the points on the circumference of the circle.Therefore, these segments are examples of radius present in the image.
The examples are,
a. Diameter: DG
b. Radius: AH, EH, DH, GH

A music store marks up the instruments it sells by 30%. If the price on a trumpet says $104. How much did the store pay for it?
Answers
Answer:
A. $ 58.50
B. $ 80
C. No, it did not mark up 30%
Step-by-step explanation:
Since,
A. We have,
Mark up percentage = 30%
Actual price = $ 45,
B. We have,
SP = $ 104,
C. We have,
AP = $ 75,
SP = $100,
Thus, mark up percentage =
= 33.33 %
Hence, store did not mark up the price by 30%.
Answer:
$ 72.80
Step-by-step explanation:
30% of 104 = 0.30 * 104
= $ 31.20
Money paid by the store = 104 - 31.20
= $ 72.80

Help me please
Answers
Answer:
The answer is x = 0
Step-by-step explanation:
-7x - 8 = x - 8(1-5x)
Simplify and FOIL.
-7x - 8 = x - 8 + 40x
-7x - 8 = 41x - 8
Add 7x to both sides.
-8 = 48x - 8
Add 8 to both sides.
0 = 48x
x can only be 0 to multiply it by any other number and get 0.
x = 0
During a 60-minute period, a traffic engineer counted 54 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 2:7. The equation LaTeX: \frac{2}{7}=\frac{t}{54-t}2 7 = t 54 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?
Answers
Answer:
Step-by-step explanation:
Given the expression for the equation representing the prediction of number of trucks as;
2/7 = t/54-t where t is the number of trucks
To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;
Given 2/7 = t/54-t
Cross multiply
2(54-t) = 7t
Open the parenthesis
2(54)-2t = 7t
108-2t = 7t
7t+2t = 108
9t = 108
Divide both sides by 9
9t/9 = 108/9
t = 21
Hence the engineers should have counted 21trucks

is the expression
[tex]a-\sqrt{b}[/tex]
And vice-versa.
The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The value of 8/9/20 could be either 0.04 or 17.77.
What is a fraction?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, the fraction is the division of the two numbers but the division is not wholly complete.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
Given the fraction,8/9/20
Case 01)
(8/9)/20 = 0.888/20 = 0.044.
Case 02)
8/(9/20) = 8/0.45 = 17.77.
Hence "The value of 8/9/20 could be either 0.04 or 17.77".

EF = 11
JK = 32
Step-by-step explanation:
Because the average of 10 and 12 is 11, therefore that would be the answer, since EF has a slite angle, finding the average of the largest side length and the opposite side would be the best way to find it.
Because the average of 28 and 36 is 32 your answer would be 32, this is from adding both lengths on LJ, which is 12 and 24, I added them to get 36, then found the average, the average was 36, meaning that this was your answer.

Qd=240-5P
Qs =P
Where qd is the quantity demanded, qs is the quantity supplied and p is the price. Determine the equilibrium quantity before the tax
Answers
Answer:
Equilibrium quantity before the tax = 40 units
Step-by-step explanation:
Given:
Qd = 240 - 5P
Qs = P
Computation:
Qd = 240 - 5P
P = 48 + Qd/5
Equilibrium quantity before the tax
Qd = 240 - 5P
P = 240 - 5P
6p = 240
p = 40
Qd = 240 - 5P
Qd = 240 - 5(40)
Qd = 40
Equilibrium quantity before the tax = 40 units
