Answer:
12 people
Step-by-step explanation:
9 divided by 3/4= 12
B = 18 because 67 - 49 = -18
-18 =-b
Divide by negative 1 because you can't have a negative variable in your answer.
There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
A=9 * 5
A=45m²
Area of triangle=
(base * height)
A=
(9*8)
A=
72
A=36m²
36+45=81m²
The area of this figure is 81m²
Answer:
The possible X values are the natural numbers.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
Step-by-step explanation:
Since we are going to observe the cars and the experiment will end when one of them turns left, and X is the number of cars observed, the possible X values will be the natural numbers (1,2,3....). Clearly we can observe any number of cars before one of them turns left. We cannot observe negative numbers of cars, or zero cars (We are going to observe at least one car), or fractions of cars.
Given the outcomes below, find their associated X values:
For this part of the problem, we are going to count how many cars we observed in total and that will be the X value.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
Answer: She should blend 98 lbs of high-quality beans.
She should blend 72 lbs of cheaper beans
Step-by-step explanation:
Let x represent the number of pounds of high quality beans that she should blend.
Let y represent the number of pounds of cheaper beans that she should blend.
She needs to prepare 170 lbs of blended coffee beans. This means that
x + y = 170
She plans to do this by blending together a high-quality bean costing $4.75 per pound and a cheaper bean at $2.00 per pound. The blend would sell for $3.59 per pound. This means that the total cost of the blend would be 3.59×170 = $610.3. This means that
4.75x + 2y = 610.3 - - - - - - - - - -1
Substituting x = 170 - y into equation 1, it becomes
4.75(170 - y) + 2y = 610.3
807.5 - 4.75y + 2y = 610.3
- 4.75y + 2y = 610.3 - 807.5
- 2.75y = - 197.2
y = - 197.2/-2.75 = 71.9
y = 72 pounds
x = 170 - y = 170 - 71.9
x = 98.1
x = 98 pounds
