Answer:
D
Step-by-step explanation:
D) The price was increased by 140% and then decreased by 85%.
Answer:
B
Step-by-step explanation:
The price was only increased by 40% because for example, the starting price was 100, then if you increased it by 140% or $140, then the price would be 240.
next, the decreased by 15% and not 85% because 100% - 15% = 85%

please solve Y Im in desperate need of help..
Answer:
Y = 10
Explanation:
We know that the left and top angles are 45°, the base is 10, and the bottom right angle is 90°, or a right angle. The simplest way I can explain this is the bottom side of the triangle is the same as the right side of the triangle. Meaning "y" would be 10 like the bottom.

Marcie heated a beaker of water in science class. The scatter plot shows the temperature (y), in degrees Celsius, of the water based on the number of minutes (x) she heated the water.
Part A: The line of best fit for this data is
y = 5.3x + 23. Use this equation to make a conjecture about the temperature of the water in the beaker if heated for 6 minutes.
A.
The water will be about 71⁰C.
B.
The water will be about 55⁰C.
C.
The water will be about 32⁰C.
D.
The water will be about 50⁰C.
Part B: What is the y-intercept in the line of best fit? What does the y-intercept represent in the scatter plot?
A.
5.3; the amount the temperature increases each minute
B.
5.3; the temperature of the water before it is heated
C.
23; the amount the temperature increases each minute
D.
23; the temperature of the water before it is heated
Answer:
Part AGiven function
y = 5.3x + 23The value of y at x = 6:
y = 5.3*6 + 23 = 54.8° CThe closest choice is :
B. The water will be about 55⁰CPart BThe y-intercept is the value of y when x = 0
y = 5.3*0 + 23 = 23° CThis is the initial temperature at zero minute time, before heating is applied.
Correct choice is:

1. In the following inequality, x = -2, what type of circle would appear on the number line (open
or closed circle) and in which direction would the arrow point on the number line(right or left)?
Also, what is a possible solution to x2 -2?
Please answer all of the questions in sentence form. *
Answer:
For number one it would be a closed circle poiting to the left because it is a negative number and it is not equal to or less than anything.
For number 2 a possible solution will be 2^2-2 which would equal 2 because 2^2=4 then 4-2=2

Jacks puppy weighed 12 pounds at its first veterinary appointment at the second appointment the puppy's weight had increased by 25% what is the weight in pounds of jacks puppy
Answer:
15 pounds
Step-by-step explanation:
Given data
Initial weight= 12 pounds
percent increase in weight = 25%
Let us find the increment
=25/100*12
=0.25*12
=3 pounds
Hence the weight in pounds of jacks puppy is
=3+12
=15 pounds
The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?
Answer:
I believe the answer will be 50+100n dollars
Step-by-step explanation:
n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.

The first one, the triangle
Step-by-step explanation:
It has three sides, and if you were to replicate the object in 3D it would have 5 vertices.
In the following triangle, find the values of the angles B and B, which are the
best approximations to the solutions to this ambiguous case?

B

A. B = 55° or B = 125°
B. B = 67° or B = 102.2°
C. B = 62.4° or B = 117.6°
D. B = 59.6° or B = 120.40
Answer: option D. B = 59.6° or B' = 120.4°
Step-by-step explanation:
Since the law is a/sinA = b/sinB = c/sinC you can try and verify each of them, by
10/sin(B)=......
and only B = 59.6° or B' = 120.4° give you the closed to 8.2/sin(45)= 11.59655121 which was 11.59401915.
(why the closed? because the question said it is "approximated")
The values of angles B and B' will be 59.6° and 120.4°, i.e. option C is the correct answer.
What is triangle ?Triangle is a three sides two dimensional surface having three angles.
We have,
A triangle in which,
One of the angle is 45°, and the side opposite to angle 45° is 8.2 with corresponding angle B.
And the side opposite to angle B is 10.
Now,
Using the law of sine,
i.e.
[tex]\frac{SinA}{a} =\frac{SinB}{b} =\frac{Sin c}{c}[/tex]
So,
According to the given triangle,
We get,
[tex]\frac{Sin 45^0}{8.2} = \frac{Sin B}{10}[/tex]
We get,
[tex]Sin B=\frac{Sin 45^0}{8.2} *10[/tex]
On solving we get,
⇒
[tex]SinB= 59.58^0\ \ or\ \ SinB= 120.42[/tex]
i.e.
[tex]SinB= 59.6^0 \ \ or\ \ SinB'= 120.40[/tex]
So,
The option C is the correct answer.
Hence, we can say that the values of angles B and B' will be 59.6° and 120.4°, i.e. option C is the correct answer.

Select the correct answer from each drop-down menu.The initial number of video views was the initial number of site visits, and the number of video views grew by the number of site visits.The difference between the total number of site visits and the video views after 5 weeks is .
Answer:
The initial number of video views was more than the initial number of site visits, and the number of video views grew by a smaller factor than the number of site visits. The difference between the total number of site visits and the video views after 5 weeks is 20,825
Step-by-step explanation:
the initial video view was 5120 and the initial number of site visits were 4800, so the initial video view was more than.
The video views grew by 5/4 and the number of site visits grew by 3/2, and since 3/2 is > 5/4, the video views grew by a smaller factor than the number of site visits.
the result for the video views after 5 weeks is 15,625 and the site visits after 5 weeks is 36450, so 36450-15,625=20,825

Given the area of a rectangle is 2x2 - 5x - 12, what is the width if the length is x – 4?
Answer:
2x + 3
Step-by-step explanation:
So, the equation here is:
[tex]\frac{2x^2 - 5x - 12}{x - 4}[/tex]
And so, using this we can set up our synthetic equation using the dividends as the coefficients of the equation, which are 2, -5, and -12; and the divisor 4, which derives from -4.
It's a bit hard to create a table here, so I'll just write out the values and hope you piece it together.
4 | 2 -5 -12
| 2 8 12
2 3 0
Thus, we are given our coefficients for our desired equation.
2x + 3
And we can ascertain this to be the answer by working the converse.
(2x + 3)(x - 4)
2x² - 5x - 12
what is the correct solution to-3x < 21?
Answer:
x > - 7
Step-by-step explanation:
Given
- 3x < 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x > - 7
The solution of inequality - 3x < 21 is,
⇒ x > - 7
We have to given that,
The inequality is,
⇒ - 3x < 21
We can simplify the inequality as,
⇒ - 3x < 21
Divide 3 both side,
⇒ - 3x /3 < 21 / 3
⇒ - x < 7
Take - 1 as common,
⇒ - x < 7
⇒ x > - 7
Therefore, The solution of inequality - 3x < 21 is,
⇒ x > - 7

Lauryn grew p tomato plants. Padma grew 5 fewer than 3 times the number Lauryn grew. Kent grew 6 more than 4 times the number Lauryn grew. Choose an expression and a simplified expression to represent the total number of tomato plants that Lauryn, Padma, and Kent grew. Select all that apply.
Answer:
A. p + (3p – 5) + (4p + 6)
D. 8p + 1
Step-by-step explanation:
A. p + (3p – 5) + (4p + 6)
B. p + (5 – 3p) + (6 + 4p)
C. p + 11
D. 8p + 1
E. 7p – 1
Lauryn = p tomatoes
Padma = (3p - 5) tomatoes
Kent = (4p + 6) tomatoes
Total number of tomato plants that Lauryn, Padma, and Kent grew = Lauryn + Padma + Kent
= p + (3p - 5) + (4p + 6)
= p + 3p - 5 + 4p + 6
= p + 3p + 4p - 5 + 6
= 8p + 1
Total number of tomato plants that Lauryn, Padma, and Kent grew = 8p + 1
A. p + (3p – 5) + (4p + 6)
D. 8p + 1

solve by system of equations by substitution and show work plz and thank you y=2x+3 y=-x-9
Answer:
X=-4, y=-5
Step-by-step explanation:
Y=2X+3
y=-x-9
substitute by inserting y value of 2nd equation (-x-9) into y value of 1st equation:
-x-9=2x+3
-x-9+9=2x+3+9
-x=2x+12
-3x=12
x=-4
solve for y by inserting x value (2) into either equation
y=2x+3
y=2(-4)+3
y=-8+3
y=-5
check answer by inserting x and y into either equation to make sure they equal:
y=2x+3
-5=2(-4)+3
-5=-8+3
-5=-5
or
y=-x-9
-5=-(-4)-9
-5=-5
