Answer:
124.5°
Step-by-step explanation:
Let the smallest angle be x. Then, the sum of the angles is an arithmetic sequence with first term x, common difference 7, and 8 terms.
Using the sum of an arithmetic series formula,
So, the third angle is 110.5+14=124.5
I'm hoping that a lot of people will come along on Brainly, see your questions, and give you as much help as you've been giving other people when you answered THEIR questions.
The total area of the garden is 97.5 square feet. 48.75 square feet of that space is planted with tomatoes, and the other 48.75 square feet is dedicated to cucumbers.
An item, x, is marked up 40% and now costs $49.99
40% is 0.40
1 times any number will be the same number so we'll use that to add on the original price to the amount of increase
(1+0.40)x=49.99
x=49.99/1.4
x=35.71 so D is the answer
Answer:
The probability is 0.97
Step-by-step explanation:
In this question, we are concerned with calculating the probability of a student spending time reading or watching TV.
To calculate this, we simply use a direct mathematical formula.
P( of spending time reading or watching tv) = P(of spending time reading) + P(spending time watching Tv) - P( of spending time watching Tv and reading)
From the question, we identify the probabilities as follows;
P(spending time reading) = 0.1
P(of spending time watching Tv) = 0.9
P(of spending time watching Tv and reading) = 0.03
Now, plugging these values, we have
P( of spending time reading or watching Tv) = 0.9 + 0.1 -0.03
= 1-0.03 = 0.97
