Answer:
Step-by-step explanation:
∠1 & ∠2 are co interior angles. co interior angles are supplementary.
∠1 + ∠2 = 180
102 + ∠2 = 180
∠2 = 180 - 102
∠2 = 78°
Answer: 0.8
Step-by-step explanation:
Let's assume that 5 puzzles were solved in 5mins. That is, 1min for each puzzle to be solved.
From our assumption, our sample size will be 5.
The probability that a subject will solve more than 1 puzzle will be number of occurrence from 2 to 5 which is 4.
This gives: 4/5 = 0.8 to one decimal place.
Answer:
y=2/9x-14.33
Step-by-step explanation:
y=2/9x- 5
then y=2/9x+b
enter points (6,-13)
-13=12/9+b
-13-12/9=b
-14.33=b
y=2/9x-14.33
First aquarium dimensions:
Length = 6 m.
Width = 4 m and
Height = 2 meter.
Second aquarium dimensions:
Length = 8 m.
Width = 9 m and
Height = 3 meter.
We know formula for volume of a cuboidal box = Length*Width*Height.
Plugging values of length, width and height of first aquarium in formula of volume. We get
V1 = 6*4*2 = 48 m^3.
Plugging values of length, width and height of second aquarium in formula of volume. We get
V2 = 8*9*3 = 216 m^3.
In order to find the total cubic meters of space do the sea turtles have in their habitat, we need to add both volumes.
Therefore, Total voulme of both aquarium = V1 +V2 = 48+216 = 264 m^3.
Therefore, total 264 m^3 cubic meters of space the sea turtles have in their habitat.
Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.
