Answer:
1/2 or 0.50
Step-by-step explanation:
To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

To make adding our two fractions easier, we need to make sure they have like denominators.

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

did the math for it!!
Answer: x = 9.0
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is x
With m∠39 as the reference angle,
the adjacent side of the right angle triangle is 7
The unknown side represents the opposite side of the right angle triangle.
To determine x, we would apply
the cosine trigonometric ratio which is expressed as
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 39 = 7/x
x = 7/cos 39 = 7/0.777
x = 9.0 to the nearest tenth
Add 3 to get a multiple of 7 with last digit 1. The only number in that range is 91, so our number is 88.
Answer:
1/5 hour or 12 minutes
Step-by-step explanation:
We can use proportions to solve this problem. Put the distance over the time
5 km 1 km
----------- = ---------
1 hour x hours
Using cross products
5x = 1
Divide by 5
x = 1/5 hour
or if we take it to minutes
1/5 * 60 = 12 minutes
