Answer: The 60th term of the arithmetic sequence -29, -49, -69, … is -1209.
Step-by-step explanation:
The given arithmetic sequence is -29, -49, -69, …
To find the 60th term of this sequence, we need to use the formula for the nth term of an arithmetic sequence:
a_n = a_1 + (n - 1)d
where a_n is the nth term of the sequence, a_1 is the first term of the sequence, n is the number of terms in the sequence, and d is the common difference between consecutive terms.
In this case, a_1 = -29 and d = -20 (since each term is 20 less than the previous term). We want to find a_60, so we substitute n = 60 into the formula:
a_60 = -29 + (60 - 1)(-20) = -29 + 59(-20) = -29 - 1180 = -1209
Therefore, the 60th term of the arithmetic sequence -29, -49, -69, … is -1209.

Step-by-step explanation:
Answer-
The probability that Erin will not have a heart attack and the test predicts that she will is, 46.5% .
Hint- This a conditional probability problem where Bayes theorem should be applied.
Solution-
Applying Bayes theorem,
Putting the values,
∴ There is a 46.5% chance that Erin will not have a heart attack even though the test predicts that she will.
Answer:
Round out to the nearest 10th say 5 it would stay 5 unlike 8 would round to 10
Step-by-step explanation:
Answer:the length of each side of the larger square is 6 centimeters.
Step-by-step explanation:
Let x represent the length of each side of the small square.
Let y represent the length of each side of the Large square.
The area of the small square is x^2
The area of the large square is y^2
The combined area of two squares is 45 square centimeters. This means that
x^2 + y^2 = 45 - - - - - - - - - - -1
Each side of one square is twice as long as a side of the other square. This means that
y = 2x
Substituting y = 2x into equation 1, it becomes
x^2 + (2x)^2 = 45
x^2 + 4x^2 = 45
5x^2 = 45
x^2 = 45/5 = 9
x = √9 = 3
Substituting x = 3 into y = 2x, it becomes
y = 2 × 3 = 6 centimeters
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If 20 gallons of fuel is used to travel 440 miles.
47.91 gallons of fuel is used to travel 1054 miles.
It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
A car uses 20 gallons of fuel to travel 440 miles.
This can be written as:
20 gallons = 440 miles
Divide both sides by 440.
20/4440 gallons = 1 miles
This means,
20/440 gallons is needed to travel for 1 mile.
Now,
20/440 gallons = 1 miles
Multiply both sides by 1054.
1054 x (20/440) gallons = 1054 miles
47.91 gallons = 1054 miles
This means,
47.91 gallons of fuel is used to travel 1054 miles.
Thus,
If 20 gallons of fuel is used to travel 440 miles.
47.91 gallons of fuel is used to travel 1054 miles.
