Answer:
a. 1/2 of Josh's cookies is the same thing as 1/2 of c which can be written as 1/2c.
b. We know that one half of the amount Josh ate is 1/2c from the previous problem. One more than that is simply 1/2c + 1.
The point A(x, y) is reflected across the x-axis to point B. Point B is reflected across the y-axis. What are the coordinates of point B'? A. (x, y) B. (–x, y) C. (x, –y) D. (–x, –y)
Answer:
The transformed point B' is: (-x, -y)
which agrees with option "D" from your list of possible solutions.
Step-by-step explanation:
In a reflection across the x-axis, the x coordinate stays the same, while the y-coordinate adopts its opposite. That is, from y it becomes "-y". Therefore, now the point (x, y) got transformed into (x, -y).
In the second step, this new point is reflected across the y-axis. Then , in such reflection, the y-coordinate stays the same, while the x-coordinate gets transformed into its opposite (x becomes "-x". So for our case, the point (x, -y) now gets transformed into (-x, -y).
Answer:
(-x-y)

Given that ABCD is a rhombus, what is the value of x?
Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
[tex](4x-25)+x=90[/tex]
[tex]4x-25+x=90[/tex] Take out the parentheses
[tex]5x-25=90[/tex] Combine like terms
[tex]5x=115[/tex] Add 25 to both sides so as to isolate the variable
[tex]x=23[/tex] Divide both sides by 5

A 17 lb dog is ordered to receive 105 mg of Clavamox BID for 14 days. IF Clavamox's concentration is 250mg/5ml, how many oz's of Clavamox will be sent home with the client?
Answer: 1 oz of Clavamox will be sent home with the client.
Step-by-step explanation:
Given, 17lb Dog is ordered to receive 105 mg of Clavamox BID for 14 days.
That means, the dog required 105 mg of Clavamox per day.
So for 14 days, the dog will need [tex]105\ mg \times 14\ days = 1470\ mg[/tex] of Clavamox
Also, the Clavamox concentration is 250 mg/5 ml
Thus, the required amount of Clavamox fotr 14 days =[tex]5 ml \div 250 mg \times 1470 mg = 29.4 \ ml[/tex]
Since, 1 oz is 29.5 ml (approximately 29.4 ml.)
So, 1 oz of Clavamox will be sent home with the client.

I NEED HELP BEFORE 1:20 P.M!
The difference between Monday's high temperature and 0°F is x. The difference between Tuesday's high temperature and 0°F is greater than x. On neither day was the high temperature was exactly 0°F. Linda claims "If I knew whether Tuesday's high temperature was above or below 0°F, I could figure out which day's high temperature was colder." Is she correct? Explain.
Answer: She is not correct because that is a dependent statement.
We do not know Monday or Tuesday’s high temperature, therefore we do not know whether Monday or Tuesday’s temperature is colder than the other’s.
But, we do know that Tuesday’s high temperature is higher than Monday’s, so we know Monday’s high is cooler than Tuesday’s
Match each of the following equations according to there slope and y intercept.
Answer:
using the equation of the line y = mx + b
m= slope
b = y intercept
y= - 1.5x - 4 m = -1.5 b = -4
y = -3x + 4 m = -3 b = 4
y = 3x m = 3 b = 0
y = 1.5x - 7 m = 1.5 b = -7
y = 7 m = 0 b = 7
Hope this helps.
Answer:
y=3x goes with m=3, b=0
y=7 goes with m=0, b=7
y=-3x+4 goes with m=-3, b=4
y=1.5x-7 goes with m=1.5, b=-7
y=-1.5x-4 goes with m=-1.5, b=-4
Step-by-step explanation:
The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains point (4, 5)?
y = −2x + 13
y = negative one halfx + 7
y = negative one halfx + 3
y = −2x − 3
Answer:
y = −2x + 13
Step-by-step explanation:
equation of line slope intercept form is y = mx +c
where m is slope and c is y intercept
when two lines are parallel then their slope are equal.
_______________________________________
Given line
CD
y = −2x − 2
it is in form of y = mx +c
thus, m = -2
Given that other line parallel to CD y = −2x − 2
Thus, its slope will be -2.
Let the equation of required line be
y = mx +c (as slope will be -2)
Then equation of line will be
y = -2x +c
Given that this line contains (4,5) it will satisfy the equation y = -2x+c
using x = 4 and y = 5
we have
y = -2x +c
5 = -2*4 + c
=> 5 = -8 + c
=> c = 5+8 = 13
Thus, equation of line parallel to y = −2x − 2 and containing point(4,5) is
y = −2x + 13
Answer:
A. y = −2x + 13

The manager of a company planed to distribute a 50 dollar bonus to each employee from the company fund. But the fund contained 5 dollars less than what was needed. Instead the manager gave each employee a 45 dollar bonus and kept the remaining 95 dollars in the company fund. How much money was in the company fund before any bonuses were paid?
Answer:
$995
Step-by-step explanation:
Let x be the number of people in the company, and y be the amount of money in the fund.
The first sentence states that 50x = y + 5
The second sentence states that 45x = y - 95
Subtracing the second equation from the first, we get 5x = 100, leading to x=20
Plugging that number into the first equation gives (50)(20) = y + 5, leading to y=995
The length of a rectangle is 4 units shorter than half the width. If the length of the rectangle is 18 units, which equation can
be used to find w, the width of the rectangle?
[tex]18 = \frac{w}{2} - 4[/tex]
[tex]18 = 4 - \frac{w}{2} [/tex]
[tex]18 - 4 = \frac{w}{2} [/tex]
[tex]18 - \frac{w}{2} = 4[/tex]
Answer:
A or the top option
Step-by-step explanation:
I used process of elimination
B simply does not work because in order for 4 to be subtracted by another number to equal 18, that number (width) would have to be negative
C also isn't correct since if it was solved out, we would add four to both sides, making the left side equal to w/2 + 4 which isn't what we want because the length is 4 shorter, not longer
D can be dealt with in the same way, by adding w/2 on both sides, making the left side 4 + w/2, the same as the previous option.

I NEED HELP PLEASEEE \6(2x – 11) + 15 = 3x + 12 Part A: Write the steps you will use to solve the equation, and explain each step. (6 points) Part B: What value of x makes the equation true? (4 points)
Answer:
x = [tex]-7\frac{2}{3}[/tex]
Step-by-step explanation:
=> 6(2x+11) + 15 = 3x+12
(Expand the brackets)
=> 12x+66+15 = 3x+12
(Adding 66+15)
=> 12x+81 = 3x+12
(Subtracting 81 and 3x to both sides)
=> 12x-3x = 12-81
=> 9x = -69
(Dividing both sides by 9)
=> x = [tex]\frac{-69}{9}[/tex]
(Simplifying)
=> x = [tex]\frac{-23}{3}[/tex]
(Converting it into mixed form)
=> x = [tex]-7\frac{2}{3}[/tex]
So, x = [tex]-7\frac{2}{3}[/tex] will make the equation true.

What is the probability that a randomly chosen person is a youngster who likes sports
car
Answer: 9/25 or 36%
Step-by-step explanation:
72 + 28 + 62 + 38 = 200
There are 200 people in total and 72 are youngsters who like sport cars.
So, the number of youngsters who like cars out of the total number of people is 72/200.
Now, find a greatest common divisor. In this case, the greatest common divisor is 8.
72 / 8 = 9
200 / 8 = 25
9/25 (fraction)
25 * 4 = 100
9 * 4 = 36
36/100 = 36% (percentage)

If a dart were thrown randomly at the dart board shown below, what is the
probability that it would land in the area between the circle with radius 2 mm
and the circle with radius 8 mm?
A. 31%
B. 48%
C. 33%
D. 45%
Answer: A. 31%
Step-by-step explanation:
First you need to find the area within each circle. This can be found by using the formula: pi * r^2
The area of the circle with radius 8mm is 64 * pi. The area of the circle with radius 14mm is 196 * pi.
196 * pi = 615.75216
64 * pi = 201.06193
Now divide the larger area by the smaller area to get how many times larger the large area is than the small area.
615.75216 / 201.06913 = 3.06239
3.06239 rounds up to 3.1
Now we know the radius of 14mm has an area 3.1 times the area of 8mm. The area of an 8mm radius has 31% of the area of a 14mm radius.
