Answer:
Letter A and B are the answers
Answer:
C and D
Step-by-step explanation:
You need to add the 2 equations together, so one equation must be negative and the other positive. You also need to make sure the coefficients to the variables are the same so you can eliminate them. Therefore, A and B are wrong and your correct choices are C and D.
Lydia graphed ΔLMN at the coordinates L (0, 0), M (2, 2), and N (2, −1). She thinks ΔLMN is a right triangle. Is Lydia's assertion correct? Yes; the slopes of segment LM and segment LN are opposite reciprocals. No; the slopes of segment LM and segment LN are not opposite reciprocals. Yes; the slopes of segment LM and segment LN are the same. No; the slopes of segment LM and segment LN are not the same.
Answer:
No; the slopes of segment LM and segment LN are not opposite reciprocals
Step-by-step explanation:
slope of LM: (2 - 0)/(2 - 0) = 1
slope of LN: (-1 - 0)/(2 - 0) = -1/2
Two lines are perpendicular when the multiplication of their slopes is equal to negative one, that is, they are opposite reciprocals. In this case:
slope of LM*slope of LN = 1*(-1/2) = -1/2
The correct option is
No; the slopes of segment LM and segment LN are not opposite reciprocals
The calculation is as follows:
slope of LM: [tex](2 - 0)\div (2 - 0)[/tex] = 1
And,
slope of LN: [tex](-1 - 0)\div (2 - 0)[/tex]= [tex]-1\div 2[/tex]
Here two lines should be perpendicular at the time when the multiplication of their slopes is equalivalent to negative one.
So,
= slope of LM × slope of LN
[tex]= 1\times (-1\div 2)\\\\ = -1\div 2[/tex]

What are the coordinates of the image of L for a dilation with center (0,0) and scale factor 1/4?
Answer:
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]
Step-by-step explanation:
Given
K(1,0)
L(1,4)
M(5,4)
N(5,0)
Scale Factor = 1/4
Dilation with center (0,0)
Required
New coordinates of the quadrilateral
To get the new coordinates, we simply multiply the scale factor with each coordinate;
This is done as follows;
[tex]If\ K =(1,0),\ then;[/tex]
[tex]K' = \frac{1}{4} * (1,0)[/tex]
[tex]K' = (\frac{1}{4} * 1,\frac{1}{4}*0)[/tex]
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]If\ L =(1,4),\ then[/tex]
[tex]L' = \frac{1}{4} * (1,4)[/tex]
[tex]L' = (\frac{1}{4} * 1,\frac{1}{4}*4)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]If\ M =(5,4),\ then[/tex]
[tex]M' = \frac{1}{4} * (5,4)[/tex]
[tex]M' = (\frac{1}{4} * 5,\frac{1}{4}*4)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]If\ N =(5,0),\ then[/tex]
[tex]N' = \frac{1}{4} * (5,0)[/tex]
[tex]N' = (\frac{1}{4} * 5,\frac{1}{4}*0)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]
Hence, the coordinates of the dilated figure are:
[tex]K' = (\frac{1}{4} ,0)[/tex]
[tex]L' = (\frac{1}{4} ,1)[/tex]
[tex]M' = (\frac{5}{4} ,1)[/tex]
[tex]N' = (\frac{5}{4} ,0)[/tex]

A photographer uses an online service to sell some of his work. The amount of money he
will make from selling 10 copies of the same photograph is given by the expression
below, where p represents the price determined for each copy:
10(0.75p - 0.5)
According to this expression, which of the following most likely describes the agreement
between the online service company and the photographer?
СА.
B.
The company keeps 25% of the amount paid for each copy and charges the
photographer $0.50 for every copy purchased.
The company keeps 25% of the amount paid for each copy and charges the
photographer $0.50 for every 10 copies purchased.
The company keeps 75% of the amount paid for each copy and charges the

photographer $0.50 for every 10 copies purchased.
C.
D.
Answer:
(A)The company keeps 25% of the amount paid for each copy and charges the photographer $0.50 for every copy purchased.
Step-by-step explanation:
The price determined for each copy=p
Given the equation : 10(0.75p - 0.5)
According to the expression,
The photographer is given 0.75p. This means the company keeps 25% of the amount paid for every copy.
Furthermore:
10 X 0.5 = $5
Therefore, the company charges the photographer $0.50 for evert copy purchased.

Of 500 dogs at a dog show, 30% are male. 2/5 of the male dogs are over the age of 3. How many dogs are male and over 3 years?
Answer: 60 dogs are male and over 3 years out of total 150 male dogs.
Step-by-step explanation:
Total no. of dogs are 500
Males are 500 x 0.3 = 150
Over 3 years are 150 x 2/5 = 60
Answer:
Total number of dogs: 500
Percent that is male: 30
Over the age of 3: 2/ 5
30 % of 500 = 150
MAKE IT INTO A FRACTION
2= 60
5 = 150
60 of the dogs are male and over 3 years.

Aliyah wants to estimate the value of the quotient of 5.68 times 10^-3 and 8.54 times 10^-9. Which statement about the value is true?
a. The value will be greater than 1 because (negative 3) divided by (negative 9) is a positive number. A number in scientific notation with a positive exponent has a value greater than 1.
b. The value will be greater than 1 because (negative 3) minus (negative 9) = 6. A number in scientific notation with a positive exponent is greater than 1.
c. The value will be less than 1 because 5.68 divided by 8.54 is less than 1. The negative exponents will make it even smaller.
d. The number will be less than 1 because 5.68 times 10 Superscript negative 3 is a very small number and division always makes the size of a number smaller.
Answer:
6.65105386*10^5
A
Step-by-step explanation:
(5.68*10^-3)/(8.54 *10^-9
when divide negative over negative it gives positive
10^-3 / 10^-9=10^6
5.68/8.54=0.665

A card is drawn one at a time from a
well-shuffled deck of 52 cards. In 11
repetitions of this experiment, 2 kings
are drawn. If E is the event in which a
king is drawn in the 11 trials, find the
experimental probability P(E).
P(E) = 11
Enter
Answer:
[tex]\dfrac{2}{11}[/tex]
Step-by-step explanation:
It is given that a card is drawn one at a time from a well-shuffled deck of 52 cards.
Total repetitions of this experiment = 11
Number of kings in the experiment = 2
Let E is the event in which a king is drawn in the 11 trials. So
[tex]P(E)=\dfrac{\text{Number of kings in the experiment}}{\text{Total repetitions of this experiment}}[/tex]
[tex]P(E)=\dfrac{2}{11}[/tex]
Therefore, the experimental probability P(E) is [tex]\dfrac{2}{11}[/tex].
Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions. I need both answers.
Answer:
1) x = 14°, y = 5°
2) x = 18.5°, y = 37°
Step-by-step explanation:
1) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 25°
∠MOD = ∠MOB + ∠BOD = 90°
3x + 23° + 25° = 90°
3x = 90° - 23° - 25°
x = 42°/3
x = 14°
∠LOB = ∠LOM + ∠MOB = 90°
5y + 3x + 23° = 90°
5y = 90° - 23° - 3(14°)
y = 25°/5
y = 5°
2) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 16°
∠EOB = ∠EOD + ∠DOB = 90°
2y + 16° = 90°
y = (90° - 16°)/2
y = 37°
∠DOF = ∠BOF + ∠DOB = 90°
4x + 16° = 90°
x = (90° - 16°)/4
x = 18.5°

Delaware was the first state to enter the Union and Hawaii was the 50th. If we order the positions of entry for the rest of the states, we find that State A entered the Union right after State B, and the product of their order-of-entry numbers is 132. Use the given information to complete each statement. State A was the th state to enter the Union. State B was the th state to enter the Union.
Answer:
State A was the 12th state to enter the Union. State B was the 11th state to enter the Union.
Step-by-step explanation:
Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:
x*(x+1) = 132
x² + x - 132 = 0
Using quadratic formula:
[tex]x = \frac{-b \pm \sqrt{b^2 -4(a)(c)}}{2(a)} [/tex]
[tex]x = \frac{-1 \pm \sqrt{1^2 -4(1)(-132)}}{2(1)} [/tex]
[tex]x = \frac{-1 \pm 23}{2} [/tex]
[tex]x_1 = \frac{-1 + 23}{2} [/tex]
[tex]x_1 = 11 [/tex]
[tex]x_2 = \frac{-1 - 23}{2} [/tex]
[tex]x_2 = -12[/tex]
The negative solution has no sense in the context of our problem, then the solution is x = 11.
What is the distance between (-2 1/2, -3) and (1, -3)
A.-3 1/2 units
B.-1 1/2 units
C.1 1/2 units
D.3 1/2 units
Answer:
D) 3 1/2Step-by-step explanation:
d = √(x₂ - x₁)² + (y₂ - y₁)²
x₂ = 1
x₁ = - 2 1/2 = - 5/2
y₂ = - 3
y₁ = - 3
d = √( 1 + 5/2)² + (- 3 + 3)²
= √(2/2 + 5/2) + 0
= √(7/2)²
= 7/2
= 3 1/2
Answer:
D
Step-by-step explanation:
(-2 1/2, -3) = (-5/2 , -3) & (1, -3)
[tex]Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(1-[\frac{-5}{2}])^{2}+(-3-[-3])^{2}}\\\\ =\sqrt{(1+\frac{5}{2})^{2}+(-3+3)^{2}}\\\\ =\sqrt{(\frac{7}{2})^{2}} \\\\=\frac{7}{2}\\\\=3\frac{1}{2}[/tex]
