If you are saying:
(3/12) - (8/12)
Then since their denominators are the same we can subtract the numerators to get our answers.
3 - 8 = -5
Following the rule of adding and subtracting fractions, the denominators will not change unless they are different.
So: (3/12) - (8/12) = -5/12
1,02x
Is your right answer
Answer:
Step-by-step explanation:
The pizza shop is offering two pizzas for the same price.
The round one is 12 inches in diameter. To know the size of the round pizza, we will determine its area. It is the same as the area of a circle which is expressed as
Area = πr^2
Radius, r = diameter /2 = 12/2 = 6 inches.
π = 3.14
Area = 3.14 × 6^2 = 3.14 × 36 = 113.04 inches square.
To know the size of the square pizza, we will apply the formula for a square
Area = l^2
Since one side is 10 inches,
The area is 10.5 × 10.5 = 110.25 inches square.
It means that the round pizza is bigger. She should by the round pizza
Answer: y=-0.6x^3- 1
Step-by-step explanation:
In the graph, first we must see the points where the line intersects the axis.
We can see that it goes throug the point (0, -1)
Now, of the given options the only two that are 0 when x is -1, are:
f1(x) =y = 0.6*x^2 - 1
f2(x) =y = -0.6x^3 - 1
We also can see that for all the positive values of x, y has a negative value, so let's value bot functions in x = 2, and see what happens.
f1(2) = 0.6*4 - 1 = 1.4
f2(2) = -0.6*8 - 1 = -5.8
so the correct option is
y=-0.6x^3- 1
Answer:
Less than 100. Z=83
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(101+116+Z)/3
300=217+Z
83=Z
