Answer:
It's around 459. So 460 if need to round
Step-by-step explanation:
So, 40 randomly chosen people do not represent the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)
Function g can be thought of as a translated (shifted) version of f(x)=x^2
Answer:
(x+4)^2-5
Step-by-step explanation:
To solve this we first need to shift the graph to the left 4 spots
We do this by adding 4 so we get
(x+4)^2
We then need the graph to go down 5 spots so we subtract by 5
This gives us
(x+4)^2-5
16.Can you use the SAS Postulate, the AAS Theorem, or both to prove the triangles congruent?
X
A. either SAS or AAS
B. SAS only
C. AAS only
D. neither
The given triangles are congruent by AAS rule.
Therefore, the correct option is C.
Given is a figure which is divided into two triangles, we need to see if the triangles are congruent or not,
So,
The triangles have one pair of sides equal [shown].
The triangles have one pair of angles equal [shown].
Now the "hidden" pair of angles that are equal are the angles which are equal by vertically opposite angle postulate, [where the triangles meet].
In AAS congruency theorem, the triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.
Therefore, we can say that the triangles are congruent by AAS congruency rule.
Therefore, the correct option is C.

Answer:
Easy. The square there is a right angle which equals 90 degrees. So 180-16-90=74 degrees
Answer:
74
Step-by-step explanation:
A traingle has 180 degrees we know one of the angles is 16 and one is a right angle meaning its 90 degrees, add 16 + 90 and you will get 106, subtract 180 from 106 you will get 74.

A landscaper wants to find the answer to the question "How much time do people in Raleigh, North Carolina, spend doing yard work in one week?" He asks the owners of all 120 houses in a Raleigh neighborhood. Which best describes the accuracy of the results of the survey? The survey results will be inaccurate because lawns in one neighborhood do not represent all types of lawns in a large city. The survey results will be inaccurate because the entire population of Raleigh should have been surveyed. The survey results will be accurate because the sample represents the population and the population is the target of the survey. The survey results will be accurate because the sample size was large enough to represent the population.
Answer:
A- The survey results will be inaccurate because lawns in one neighborhood do not represent all types of lawns in a large city.

Give triangle ABC is a right triangle, and angle A is the right angle. If sin(B)=3/5, find the cos(B).
Answer:
Cos B = 4/5
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine B = 3/5
Cos B =?
Recall:
Sine B = Opposite / Hypothenus
Sine B = 3/5
Therefore,
Opposite = 3
Hypothenus = 5
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = 3
Hypothenus = 5
Adjacent =?
Hypo² = Adj² + Opp²
5² = Adj² + 3²
25 = Adj² + 9
Collect like terms
Adj² = 25 – 9
Adj² = 16
Take the square root of both side
Adj = √16
Adjacent = 4
Finally, we shall determine Cos B. This can be obtained as follow:
Hypothenus = 5
Adjacent = 4
Cos B =?
Cos B = Adjacent / Hypothenus
Cos B = 4/5

Trisha is making two sides of hamburgers 0.5 pounds and 0.25 pounds how many of each size of hamburgers could she make with 3.75 pounds of hamburger
Answer:
for 0.5 pounds size, we have 7.5
for 0.25 pounds size, we have 15
Step-by-step explanation:
Here, we want to calculate the number of each hamburger size that could be made
for 0.5 pounds size, we have that;
3.75/0.5 = 7.5
for 0.25 pounds, we have;
3.75/0.25 = 15

Find the equation of the line that passes through point a and b
Answer:
An equation of the line that passes through point a and b, is y = 2x + 5.
.
Step-by-step explanation:
☆To find the slope, you can follow the slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Plug in!
[tex]m = \frac{ - 1 - 7}{ - 3 - 1} = \frac{ - 8}{ - 4} = 2[/tex]
☆This is the slope-intercept equation:
[tex]y = mx + b[/tex]
☆You have to plug in and solve for b, aka the y-intercept. Plug in the slope and the one set of coordinates.
[tex]y = mx + b \\ \\ 7 = 2(1) + b \\ 7 = 2 + b \\ \frac{ - 2 = - 2 \: \: \: \: \: \: \: \: \: \: \: }{5 = b \: \: \: \: \: \: \: \: \: \: } [/tex]
☆Now that we have the slope and y-intercept. We just need to put them together.
☆y = 2x + 5
Find apolynomial function of degree3 f(10)=17,and thezeros are 0,5 and8
Given:
Degree of a polynomial = 3
Zeros of the polynomial = 0,5,8
f(10)=17
To find:
The polynomial function.
Solution:
The general form of a polynomial is
[tex]P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}[/tex]
Where, a is a constant, [tex]c_1,c_2,...,c_n[/tex] are zeros with multiplicity [tex]m_1,m_2,...,m_n[/tex] respectively.
Since, 0,5,8 are zeros of the polynomial, therefore, (x-0),(x-5), (x-8) are the factors of required polynomial.
[tex]f(x)=a(x)(x-5)(x-8)[/tex] ...(i)
Putting x=10, we get
[tex]f(10)=a(10)(10-5)(10-8)[/tex]
We have f(10)=17.
[tex]17=a(10)(5)(2)[/tex]
[tex]17=a(100)[/tex]
[tex]\dfrac{17}{100}=a[/tex]
[tex]0.17=a[/tex]
Putting a=0.17 in (i).
[tex]f(x)=0.17(x)(x-5)(x-8)[/tex]
Therefore, the required polynomial is [tex]f(x)=0.17(x)(x-5)(x-8)[/tex].

Each sheep has 4 legs and each chicken has 2 legs. If I count 50 heads and 140 feet total, how many sheep are there?
Answer:
[tex]20\:\mathrm{sheep}[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}2c+4s=140,\\c+s=50\end{cases}[/tex], where [tex]c[/tex] is the number of chickens and [tex]s[/tex] is the number of sheep.
Multiply the second equation by [tex]-2[/tex] and add both equations to solve for [tex]s[/tex]:
[tex]\begin{cases}2c+4s=140,\\-2c-2s=-100 \end{cases},\\2s=40,\\s=\fbox{$20$}[/tex].
