We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:
\frac{2}{x}=\frac{1}{40}
=\frac{2*40}{1}=x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:
\frac{1.5}{y}=\frac{1}{40}
\frac{1.5*40}{1}=y
60 cm=y 
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION

What are all values of x for which the series n 3^n/x^n converges
Eva8 [605]

The interval of the convergence is x < -3 or x > 3 if the series n 3^n/x^n goes infinitely.

<h3>What is convergent of a series?</h3>

A series is convergent  if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.

We can find the interval for the convergent by root test.

Like the Ratio Test, the root Test is used to determine absolute convergence (or not) with factorials, the ratio test is useful.

For the given series:

\sum^{\infty}_{n=0}\dfrac{3^n}{x^n}

As the series goes infinitely, we can use root test.

By the root test, the convergence interval will be;

The interval of convergence is:

x < -3 or x > 3   we can write this as:

|x| < 3

Thus, the interval of the convergence is x < -3 or x > 3 if the series n 3^n/x^n goes infinitely.

11) In a triangle, the ratio of the measures of three angles is 2:5:8. Find the measures of
natta225 [31]

Answer:

Sum of interior angles of a triangle always = 180 degrees

add the individual ratios to get a sum composite ratio:

2+5+8 = 15

180 / 15 = 12

Multiply individual ratios:

{2:5:8} * 12 = 24:60:96

Check:

24 + 60 + 96 = 180

Step-by-step explanation:
