The coefficient of b is h/2. Multiply the equation by the reciprocal of that.
(2/h)A = (2/h)·(h/2)·b
b = 2A/h . . . . . simplify
$60 ÷ $15 = 4
$9 × 4 = $36
he saved $36 when he earned $60
Answer:
<u>Number of rooms reserved for the students are - 90 .</u>
Step-by-step explanation:
Firstly ,
As we know 60% of the 600 students went on the trip,
Then ,
Number of students went on the trip = 60% of 600
=
= 360
Now ,
Given - One room is reserved for 4 students ,
Therefore , Number of rooms for 360 students =
= 90
<u>Hence , the answer is 90 rooms reserved for the students.</u>
Answer:
Equation: 2x + 3x + 10 = 180
x = 34
Top angle = 68 degrees
Bottom angle = 112 degrees
Step-by-step explanation:
The two angles add to 180, so set them equal to 180.
2x + 3x + 10 = 180
5x + 10 = 180
- 10 - 10
5x = 170
/ 5 / 5
x = 34
Plug x into angles,
2(34) = 68
3(34) + 10 = 112
We have composite shape consisting of two rectangles with dimensions of one rectangle as 20 feet by (10-6) feet and other rectangle as 6 feet by (20-17) feet.
We know the formula for area of rectangle is given as follows :-
Area of Rectangle = Length x Width
First rectangle's area would be = 20 feet x 4 feet = 80 square feet.
Second rectangle's area would be = 6 feet x 3 feet = 18 square feet.
Area of the room = First rectangle's area + Second rectangle's area.
Area of the room = 80 + 18 = 98 square feet.
Hence, final answer is 98 square feet.
