Answer to 1+4=5 2+5=12 3+6=21 8+11=?

Answers

Answer 1
Answer: It appears that each consecutive answer is added to the next operation such that  ((1+4)=5)+2+5=12, because 2+5=7, but when added to (1+4), the answer is 12, and so on. 

Thus, 
(1+4)=5 + (2+5)=12 + (3+6)=21 + (8+11)=40
Answer 2
Answer: the answer will be 19

Find the 60th term of the arithmetic sequence −29,−49,−69,

Answers

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.

Suppose Adriana spends $ 73.00 dollars on T-shirts and pants. A T-shirt costs $5.50 and pants cost $25.50. How can you represent this situation with an equation?

Answers

Answer:

73.00=5.50x+25.50y

Step-by-step explanation:

Answer:

25.50x + 5.50y = 73.00

Step-by-step explanation:

Pick a variable for x and y (x is pants and y is T-shirt)

Since she buys pants and T-shirts you add the two values

Since she spent $73 you make it equal to 73

Trevor drew lines of best fit for two scatter plots, as shown. Which statement describes the placement of the lines Trevor drew?

Answers

Answer:

A)Only Line A is well placed line of best fit

Step-by-step explanation:

Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line

The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit

By considering both the given graphs

We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit

So,Option A is true

A)Only Line A is well placed line of best fit

Answer: a) only line A is a well placed line of best fit

Step-by-step explanation:

A lizard needs to stay a safe distance from a cactus. The diameter of the cactus is 12 inches. If the lizard is 8 inches from a point of tangency, find the direct distance between the lizard and the cactus (x). If necessary, round to the hundredths place.

Answers

Answer:

10 in

Step-by-step explanation:

We are given that

Diameter of cactus=d=12 in

Radius of cactus=(d)/(2)=(12)/(2)=6 in

Distance of lizard from point of tangency=8 in

We have to find the direct distance between lizard and cactus.

In triangle OAB,

OA=6 in

AB=8 in

Pythagorous theorem: (Hypotenuse)^2=(base)^2+(perpendicular\;side)^2

Using pythagorous theorem

OB^2=(6)^2+(8)^2=100

OB=√(100)=10 in

Hence, the direct distance of lizard from cactus=10 in

the answer should be 6 if i am right
