Identify the height of a triangke in whixb b = 12 m and A = (18x - 6) m^2
Answer:
h = (3x − 1) m
Step-by-step explanation:
(12x5+3x25)-8
12x5=60
3x25=75
60+75=135
135-8=127
Answer:
127
Step-by-step explanation:
A triangle has one angle of 120 degrees what must be true about the other two angles A- the sum of the two angles must be equal to 120 degrees. B- the two angles must be the same measure C- the sum of two angles must be 60 degrees
Answer:
C
Step-by-step explanation:
A triangles sum of all the angles will be 180, so since we already have one as 120, then that least 60. So the sum of the two extra angles has to be 60.

A scientist is studying the motion of waves by measuring the distance between the crests and troughs of waves in a particular area. He set up a
series of buoys at equal intervals, and attached a depth detector to each buoy.
After gathering data, the scientist modeled the positions of the buoys at a specific instance with the
given function, where x is the horizontal
distance, in feet, from the first buoy and 1() is the depth of the water, in feet, at that location.
f(3) = 2cos(61) + 13
Select the correct representation of the buoy positions modeled by function f.
Answer:
i got it right on the test
Step-by-step explanation:
The correct representation of the buoy positions is modeled by function f shown in picture (B) option (B) is correct.
What is cos function?It is defined as a function that is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a]where is the amplitude of the function.
We have:
A scientist studying the motion of waves by measuring the distance between the crests and troughs of waves in a particular area.
The equation he set up:
f(x) = 2cos(πx/8) + 13
As we know the cos function has a maximum value is 1 and a minimum value is -1
The maximum value:
f(0) = 2(1) + 13
f(0) = 2 + 13
f(0) = 15
The minimum value:
f(8) = 2(-1) + 13
f(8) = -2 + 13
f(8) = 11
Thus, the correct representation of the buoy positions is modeled by function f shown in picture (B) option (B) is correct.

The circumference of a circular garden is 138.16 feet. What is the radius of the garden? Use 3.14 for it and do not round your answer.
Il feet
?
Answer:
11 feet
Step-by-step explanation:
The radius of the circular garden is approximately 22 feet.
The formula to calculate the circumference of a circle is given by:
C = 2πr
where C is the circumference and r is the radius of the circle.
We are given the circumference as 138.16 feet, so we can set up the equation:
138.16 = 2 * 3.14 * r
To solve for the radius (r), we can rearrange the equation:
138.16 = 6.28r
Dividing both sides of the equation by 6.28:
138.16 / 6.28 = r
r ≈ 22
Therefore, the radius of the circular garden is approximately 22 feet.

On the main floor of the Kodak Hall at the Eastman Theater, the number of seats per row increases at a constant rate. Lucas counts 31 seats in row 3 and 37 seats in row 6. How many seats are there in row 20?
67
61
63
65
Answer:
67
Step-by-step explanation:
There are 65 seats in row 20, option D is correct.
Given that number of seats in row 3 are 31.
Number of seats in row 6 are 37
We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:
Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)
Rate of increase = (37 - 31) / (6 - 3)
Rate of increase = 2
So, the number of seats increases by 2 seats per row.
To find the number of seats in row 20, we can use the rate of increase:
Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))
Number of seats in row 20 = 31 + (2× (20 - 3))
= 31 + (2 × 17)
= 31 + 34
= 65
Therefore, there are 65 seats in row 20.

Kant's sister has 150 red marbles and 360 pink marbles and she wants the same number of marbles on each row, what is the least number of rows she can make ?
Answer:
We know that Kant's sister has 150 red marbles and 360 pink marbles.
She separates the marbles in rows, such that each row must have the same number of marbles.
The least number of rows she can make is when she puts N marbles in each row, such that N is the greatest common factor between 150 and 360.
To find the greatest common factor between 150 and 360 we can write them as the product of prime numbers.
150 = 15*10 = (3*5)*(2*5)
360 = 36*10 = (6*6)*(2*5) = (2*3*2*3)*(2*5)
Here we can see that the factors: 2, 3, and 5 appear (at least) one time in each number, this means that the greatest common factor between 150 and 360 is the product of these 3 factors:
GCF = 2*3*5 = 30
This means that we need to make rows with 30 marbles each.
and we will have:
150/30 = 5 rows of red marbles
360/30 = 12 rows of pink marbles.
A total of 5 + 12 = 17 rows.

A parallelogram with a height of 2x+3 has an area listed below. What is the length of the base of the parallelogram? 2x^2+13x+15
Answer:
x+5
Step-by-step explanation:
I thought what 2 numbers if multiplied made 15
also 2x+3 already has a 3
so I'm guessing 3 and 5
then I put them next to each other
(2x+3) ( +5)
I put a x in the second parenthesis as a guess because the area had a 2x^2 in it . that could only happen with 2x * x
so (2x+3) (x+5)
