Answer:
The sum of all angles should be 180°
Step-by-step explanation:
Sum of all angles in a triangle = 180°
115° + 39° = 154°
180° - 154° = 26°
The student found 206°, lets add 206° to 154° and see what we get.
206° + 154° = 360°
Prediction : The student may have forgotten that the sum of all angles in a triangle equals 180° and not 360°
Answer: The sum of all angles should be 180°

The base of a basketball goal has the shape of a rectangular pyramid The base goal must be gilled with sand so the goal does not fall down The base of the pyramid 4.5 feet long and 4 feet wide. The height of a pyramid is 2.5 feet. How much sand be needed to fill the base of the basketball goal?
Answer:
15 ft^3
Step-by-step explanation:
Sand needed can be determined by calculating the volume of a pyramid
Volume of a pyramid = 1/3 x ( length base x height)
1/3 x ( 4.5 x 4 x 2.5) = 15 ft^3

what is the equation of this line
a. y = -3/2x+9
b. y = -2/3x+18
c. y = 2/3x+6
d. y = 3/2x+6
Answer:
A. y = -3/2x + 9
Step-by-step explanation:
In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.
Answer:
a
Step-by-step explanation:
any two points on the line are
(0,9 ) and (4,3)
slope=(3-9)/(4-0)=-6/4=-3/2
y intercept is 9
so eq. of line is y=-3/2x+9

Which of the following is an inscribed angle in the diagram below?
Answer:
A
Step-by-step explanation:
Given: α is an angle in the second quadrant, csc α = 25/7; β is an angle in the first quadrant, cos β = √2/2. The value of tan ( α - β ) = _____.
-3/17
29/17
-31/17
15/17
Answer:
-31/17
Step-by-step explanation:
csc²α-cot²α=1
cot²α=csc²α-1=(25/7)²-1=(625-49)/49=576/49
α is in 2nd quadrant so cotα is negative.
cot α=-√(576/49)=-24/7
tan α=-7/24
cos β=√2/2
sec β=2/√2=√2
sec²β-tan ²β=1
tan ²β=sec²β-1
tan²β=(√2)²-1=2-1=1
β is in 1st quadrant ,so tan β is positive.
tan β=1
[tex]tan (\alpha -\beta )=\frac{tan \alpha -tan \beta }{1+tan \alpha tan \beta } \\=\frac{\frac{-7}{24} -1}{1+(\frac{-7}{24}) (1)} \\=\frac{-7-24}{24-7} \\=\frac{-31}{17}[/tex]

If 3/7 is written as a decimal, will the digits after the decimal eventually repeat?
A.Yes, because
is an irrational number.
B. Yes, because

Answer:
Yes, because its an rational number
Step-by-step explanation:
Solution: by division.
3/7 = 0.42857142857142857142…..
As you can see, the first six decimal places make a loop and become repetitive.
Then I proceeded to divide 100/6. That equals 16 remaning 4. Then counted four digits from0.428571. The 100th digit equals 5.

The circumference of a circle is 15 centimeters. What is the diameter? Round to the nearest hundredths place.
Answer:
4.77
Step-by-step explanation:
because Circumference can be found with this equation
C = 2piR
we need to plug in 15 for Circumference and solve for its radius or R.
15 = 2piR
15/2pi = R
but we need diameter which is 2R so we just need to multiply the answer by 2.
15/2pi × 2 = Diameter
15/pi = D
approximately = 4.77

First we count the number of beans in total which is 20
Then we count the number of red beans which is 6
6/20 can be simplified to 3/10
Answer:
C) 3/10
Step-by-step explanation:
There are 6 red + 5 blue + 4 green + 5 black = 20 jelly beans in total
Since there are 6 red jelly beans, the probability of randomly selecting a red jelly bean is 6 red jelly beans / 20 total jelly beans = 6/20 = 3/10

Arthur, Kyle, and Tom are all on the baseball team. At the end of the season, they compared how many home runs each of them hit. Arthur noticed that if he doubled the number of home runs he hit and then subtracted 1, he would get the number of home runs Kyle hit. Tom noticed that if he subtracted 1 from the number of home runs he hit and then doubled that number, he would get the number of home runs Kyle hit. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Arthur hit, a. Enter your response in the first response box. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Tom hit, t.
Answer:
k = 2a - 1
k = 2(t - 1)
Step-by-step explanation:
Let :
Number of home runs Arthur hit = a
Number of home runs Kyle hit = k
Number of home runs Tom hit = t
Kyle's home runs, k in terms of Arthur's home run : Double the value of a ; then subtract 1
k = 2a - 1
Kyle's home runs in terms of Tom's home runs ;
Subtract 1 from t `
k = 2(t - 1)

The 4th term of a geometric sequence is 48, and the common ratio is 2. What is the first term of the sequence?
*There are no answer choices available on Kydor*
Thank you so much for your help!
Answer:
6
Step-by-step explanation:
[tex]nth \: term \: of \: geometric \: \\ sequence \: is \: given \: as : \\ a_n = a {r}^{n - 1} \\ (a = ?, \: \: r = 2)\\ \\ a_4 =48......(given) \\ \\ \therefore \: a {(2)}^{4 - 1} = 48 \\ \\ \therefore \: a {(2)}^{3} = 48\\ \\ \therefore \: 8a = 48 \\ \\ \therefore \: a = \frac{48}{8} \\ \\ \therefore \:a = 6[/tex]
Answer:
6
Step-by-step explanation:
geometric sequence is given as Tn=ar^n-1
where Tn is the last term,a is the first term, r is the common ratio, n is the nth term
hence 48=a2^(4-1)
48=a2^3
48=a8 (divide both by 8 to ramain with a)
6=a
therefore the first term is 6 .
The domain (input values) of the sine function is:
O A. values between 0 and a radians,
O B. all real numbers.
O C. values less than 90%.
D. values less than 27 radians,
Answer:
The domain (input values) of the sine function is:
O B. all real numbers
The domain of the sine function will be all real number. Then the correct option is B.
What are domain and range?The domain means all the possible values of x and the range means all the possible values of y.
Simply put, trigonometric functions also referred to as cyclic capabilities the functions of a triangle's inclination.
Let the sine function be f(x) = sin x.
It is a function that repeats itself in a particular time interval.
The domain of the sine function will be all real number.
And the range of the sine function will be [1, –1].
Then the correct option is B.
The graph of the sine function is given below.
