A bus rental company charges $60 for booking a bus and $120 for each hour the bus is rented. A tour group pays $780 to rent a bus. HELP WANTED TY!!
Select the equation that represents the given situation and find the number of hours the tour group rented the bus.
A. 60x + 120 = 780 ; 11 hours
B. 60x + 120 = 780 ; 6 hours
C. 120x + 60 = 780 ; 11 hours
D. 120x + 60 = 780 ; 6 hours
Answer:d. 120x+60=780
Step-by-step explanation:
120 cost per x hours
Flat Rental cost 60
120x+60=780
-60 as the flat rate which won’t change based on time.
120x=720
Divided by a rate of 120 per hour
x=6 hours
If cos(2/3x+20)°=sin(2x−10)°, find the acute angles of the corresponding right triangle.
A =
B =
Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50

58 is the difference of Janelle's height and 24.
Use the variable j to represent Janelle's height.
Answer:
Janelle's height is 82 units.
Step-by-step explanation:
Let j represent Janelle's height.
It is mentioned that, 58 is the difference between Janelle's height and 24.
Mathematically, we can write it as :
j-24 = 58
We can solve it as follows :
Adding 24 both sides,
j-24+24 = 58+24
j = 82
Hence, Janelle's height is 82 units.

if each interior angle of a polygon is 144 . find the polygon
Answer:
Decagon
Step-by-step explanation:
Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees.
For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees.
Hence, the number of sides = the number of vertices = 360/36 = 10.
Answer. Your polygon is decagon with 10 sides (vertices).

0.7 times square root of 300
-0.125 times square root of 192
Answer:
To factor the first expression, "0.7 times square root of 300", we can rewrite it as:
0.7 * sqrt(300)
The prime factorization of 300 is 2 * 2 * 3 * 5 * 5, so we can rewrite the expression as:
0.7 * sqrt(2 * 2 * 3 * 5 * 5)
Since the square root of a number is the same as the square root of that number's prime factorization, we can rewrite the expression as:
0.7 * sqrt(2) * sqrt(2) * sqrt(3) * sqrt(5) * sqrt(5)
Combining like terms, we get:
0.7 * 2 * sqrt(2) * sqrt(3) * sqrt(5)
= 1.4 * sqrt(2) * sqrt(3) * sqrt(5)
This is the fully factored form of the expression "0.7 times square root of 300".
To factor the second expression, "-0.125 times square root of 192", we can rewrite it as:
-0.125 * sqrt(192)
The prime factorization of 192 is 2 * 2 * 2 * 2 * 2 * 2, so we can rewrite the expression as:
-0.125 * sqrt(2 * 2 * 2 * 2 * 2 * 2)
Since the square root of a number is the same as the square root of that number's prime factorization, we can rewrite the expression as:
-0.125 * sqrt(2) * sqrt(2) * sqrt(2) * sqrt(2) * sqrt(2) * sqrt(2)
Combining like terms, we get:
-0.125 * 6 * sqrt(2)
= -0.75 * sqrt(2)
This is the fully factored form of the expression "-0.125 times square root of 192".

On solving the provided question, we can say that - the perimeter chest won't fit next to her bed, thus the answer is no.
What is a perimeter?The perimeter of a form is determined by the length of its contour. A rectangle or square's perimeter is determined by adding the widths of its four sides. In this instance, the rectangle's length and breadth are represented by x and y, respectively. The surface of a form is used to compute its area.
Given here is: In her room, it is 86 inches wide. The width of the bed is 76 inches.
She also wants to accommodate a chest of drawers that is 72 centimeters broad, which equals inches.
=> 90 cm = 24.6546536565 inches
and the space left in her room = 86-76=10 inches
thus, the chest will not fit next to her bed

Consider a situation in which P(A) = , P(C) = , and P(A and B) = . What is P(B and C)?
The probability of P(B and C) is 1/6
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty. It is more likely that an event will occur if its probability is higher.
For e.g., A straightforward illustration is tossing a fair (impartial) coin.
Given that, the probabilities, P(A) = 1/8, P(C) = 1/4, and P(A and B) = 1/12
P(A and B) = P(A)×P(B)
Therefore,
1/12 = 1/8 × P(B)
P(B) = 8/12 = 2/3
Now,
P(B and C) = P(C)×P(B)
P(B and C) = 1/4×2/3
P(B and C) = 1/6
Hence, P(B and C) = 1/6

Answer:
Part A: 4,300 ≥ 2500 + 0.12s
Part B: Less than or equal to $15,000
Part C: In the image
Step-by-step explanation:
For Part A: The total needs to be at least 4,300. So 4,300 is greater than or equal to how much she earns. 2,500 is the base pay, and it is added to 0.12s, which represents 12% of sales (s).
For Part B:
Using the inequality, solve for s
4,300 ≥ 2500 + 0.12s
Subtract 2500 from both sides
1800 ≥ 0.12s
Now divide both sides by 0.12 to isolate s
15000 ≥ s
So sales must be less than or equal to 15000.
