3. If F, G, and H are the midpoints of the sides
of AJKL, FG = 37, KL = 48, and GH = 30,
find each measure.
K
a) FH =
G
b) JL =
c) KJ =
d) FJ =
Answers
Answer:
Step-by-step explanation:
(a). FH = KL / 2 = 48 ÷ 2 = 24
(b). FG = JL / 2 = 37 ⇒ JL = 2 × FG = 74
(c). KJ = 2 × GH = 2(30) = 60
(d). FJ = KJ ÷ 2 = 30

The lowest and leftmost note on a piano keyboard is an A. The next lowest A is seven white keys to the right. This pattern continues. Write an explicit formula for an arithmetic sequence to represent the position of each A key on the piano, counting from the left. If a piano has 52 white keys, in what position is the key that plays the highest A?
Answers
Answer: Not sure but this may help!
Step-by-step explanation:
A = 7 —>
52 keys which means A is 7 keys to the right and there is about 7 A keys. 52 divided by 7 = around 7. I don’t know the question but I need points!

find the domain of (5y-8)/11
Answers
The domain of the function f(y) = (5y - 8)/11 is the set of all real numbers.
Dom(f(y)) = R.
What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given a function f(y) = (5y - 8)/11.
It is a real function and the domain of the function is the set of all real numbers.
There are no restrictions as the denominator is constant and no such values of 'y' make the denominator zero.

Answer:
b=121, a and c=59
Step-by-step explanation:
b and 121 are congruent angles, so they are equal to each other.
each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.
a and c are congruent angles so they are also equal to each other

Considering the sides as vectors, we have:
[tex]\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}[/tex]
Once
[tex]\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)[/tex]
[tex]\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)[/tex]
[tex]\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)[/tex]
[tex]\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}[/tex]

David loves to cook! He knew 21 recipes before starting cooking school and he learns 2 recipes
every 1 one week. An equation to represent that is y = 21 + 2x where x represents number of
weeks and y represents number of recipes.
His friend Sarah believes that if he attends school for 10 weeks that means he knows 42 recipes.
Explain if she is correct.
Answers
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.
Answer:
Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.
Step-by-step explanation:
To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:
y = 2x + 21
42 = 2(10) + 21
42 = 20 + 21
42 [tex]\neq[/tex] 41
Sarah is wrong.

If the measures of two sides of a triangle are 3 feet and 7 feet which is the least possible whole number measure for the third side
Answers
Answer:
5,6,7,8,9 ft
Step-by-step explanation:
7-3 < x < 7+3
x < 10
x= 5,6,7,8,9
longest side must be less than the sum of the legnths of the other 2 sides
if we assume that 7 is longest then missing side is x so
3+x>7
minus 3
x>4
whole number to satisfy is
x=5
if we assume the missing side is the largest
3+7>x
10>x
x is 9 at most
if the third side is not the longest side, it can be 5 at minimum
if the third side is the longest side, it can be 9 at max
so the third side can be 5,6,7,8,9 ft

x/5=3
Multiply both sides by 5
5*x/5=3*5
The 5’s on the left side cancel out so your left with...
x=15
b)
x/2=8.5
Multiply both sides by 2
2*x/2=8.5*2
The 2’s on the left side cancel out so your left with...
x=17

A study compared the number of years of education a person received and that person's yearly salary. It was determined that the relationship between these two quantities was linear and the correlation coefficient was 0.91. Which conclusion can be made based on the findings of this study?
Answers
Answer:
Salary earned increases as the number of years of education earned increases.
Step-by-step explanation:
Given that the correlation between the number of years of education a person receive and his yearly salary yields a linear relationship with a correlation Coefficient of 0.91, this shows that a strong positive relationship exists between the two measured quantities, this is deduced by the positive nature of the correlation Coefficient value obtained and the fact that the value of the Coefficient is close to 1. Hence, salary earned increases as the number of years of education increases and Vice versa.

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answers
Answer:
[tex]Volume = 18312.48[/tex]
Step-by-step explanation:
Given
[tex]Height (h) = 18mm[/tex]
[tex]Radius (r) = 18mm[/tex]
Required
Determine the volume
The volume of a cylinder is calculated as thus:
[tex]Volume = \pi r^2h[/tex]
Substitute values for r and h
[tex]Volume = 3.14 * 18^2 * 18[/tex]
[tex]Volume = 18312.48[/tex]
Hence, the volume of the cylinder is 18312.48mm³
