Part 2

Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
A. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
B. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
Step-by-step explanation:
Part 1:
Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.
Part 2:
Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone?
Answer:
The original price of the cell phone is $514.29
Step-by-step explanation:
The answer is $514.29 because the equation to find the answer is :
Let x = the original price of the cell phone
$180 = Price after discount
So, 180 = x * 35/100
Multiply by its reciprocal on both sides so
180 (100/35) = x
18000/35 = x
514.29 = x
So the original price of the cell phone is $514.29
The number of students in a school is about 13⁴. How many students does this expression represent?
Answer: 28561
In order to find the answer you need to multiply 13 four times creating the equation 13*13*13*13 which then gives you 28561
Pleas help wuickly with this question for studying for my math test
Answer:
D - 320
Step-by-step explanation:
You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!

Solve the equation for all values of x by completing the square.
x^2 + 6x – 27 = 0
Answer:
Solution
=3
=−9
x=3
x=−9
x=3x=−9
Step-by-step explanation:
Boom
Answer:
x=-9 and 3
Step-by-step explanation:
FOIL method
x^2+6x-27=0
Find the common numbers that multiply to 27 that will also equal 6.
(27x6) or (9x3)
the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.
then FOIL them
(x+9)(x-3)
FIRST: x*x=x^2
OUTSIDE: x*-3=-3x
INNER: 9*x=9x
LAST: +9*-3=-27
x^2(-3x9x)-27
x^2+6x-27
now that the equation matches you solve for x.
(x+9)=0 x=-9
(x-3)=0 x=3
Triangle BCD With Vertices B(4,4), C(8, 14), And P(12, 0); K = 1/4
Answer:
Hello, I am not sure if you mean a dilation by 1/4. If it is, this will be the answer:
B (1, 1)
C (2, 3.5)
D (3, 0)
Step-by-step explanation:
Just divide each number by 4. B (4, 4) = B (4/4, 4/4) = B (1, 1)
Continue to do this for each coordinate set given.
Hope this helps!
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.

Hi!
It seems like you have two answers in the boxes already, but it is not correct.
Firstly, you cannot tell mean from a box plot. The first box should be moved to the last category.
Your second boxes seems to be correct though.
As far as the remaining boxes, I can help with those too!
Median: The median is identifiable in a box plot, as the line in the boxes themselves are the medians. The medians do line up, therefore they belong in category 1.
Minimum: This is the value that is the least. We can tell this from a box plot, by looking at the most left line, or the "whiskers", as some teachers call them. For our box plots, the minimum is 4. They line up exactly. Therefore, this box should go in the first category.
IQR: The IQR "measures the spread of the middle half of your data". In these box plots, the IQR is different. Therefore, it belongs in the second category.
Mode: This is the value that appears most often in a set of data values. You cannot tell this from a box plot. Therefore, it belongs in the last category.
I hope I could help!

A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.

(2+3)+( 2/3+1/2)
=5 and then you multiply each fraction by the other denominators
2/3 x 2 and 1/2 x 3
=5 4/6 3/6
Now add each fraction because it is the same denominator
4+3=7 so it is 7/6 now to make it a mixed fraction
7/6=1 1/6
5 +1=6
6+1/6 = 6 1/6

A special machine is used at a construction site to dig holes. A hole is dug to a depth of 4.75 feet when the machine hits rock. The progress slows to 3/5 feet per hour of digging. The depth of the hole must be at least 12 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.
Answer: 12 h ; 45 m
Step-by-step explanation:
*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.
What we know:
Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine worksHow to solve:
By setting up an algebraic equation, we can solve this.
Process:
Set up equation 4.75 + 3/5x = 12 1/2Convert 19/4 + 3/5x = 12 1/295/20 + 12/20x = 250/20
Subtract -95/20 -95/2012/20x= 155/20
Isolate x via division /(12/20) /(12/20)+Simplifyx= 12 11/20
Convert 12 h 33 mSolution: 12 ; 45
The minimum amount of time taken by the machine will be 12 hours and 55 minutes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.
Convert the mixed fraction number into a decimal number.
12 ¹/₂ feet = 12.5 feet
Let 'x' be the time. Then the equation is given as,
(3/5)x = 12.5 - 4.75
Simplify the equation, then we have
(3/5)x = 12.5 - 4.75
(3/5)x = 7.75
x = 12.9167
x = 12 + 0.9167 x 60
x = 12 hours and 55 minutes
The base measure of time taken by the machine will be 12 hours and 55 minutes.
