Answer:

Its 60 60 60

Step-by-step explanation:

240 Divided by two makes two of the interior angles 60 therefore since triangles must have 180 degrees total the final angle must be 60 as well

The measures of the interior angles together would be 40 degrees, but separate, they would be 20 degrees.

Answer: 3

Step-by-step explanation:

Given

$f(x)=\dfrac{1}{3}3^x$

$g(x)=2x+4$

For $f(x)$ to be true, the domain is given by observing the graph of two i.e. $x\in (-1.981,3.117)$ . In this range $g(x)$ is greater than $f(x)$ .

From the above domain largest integer that can satisfy the condition is 3.

The difference between two positive integers is 3. If the smaller is added to the square of the larger, the sum is 87.

Komok [63]

Let x be larger integer so x-3 is the smaller
so x^2+ x-3 = 87
x^2 +x -90=0 and factor
(x-9)(x+10)=0
x=9 or x=-10 but x must be positive
so x=9 and smaller number is 6

Juan and Nina are in the Junior High Orchestra. As part of the orchestra they each have to learn two instruments. Juan is learni

Answer:

Nina practiced the viola for 11.25 hours last week.

Step-by-step explanation:

Juan practiced the violin for 9 hours last week. For each 3 hours that he practices the violin, he practices 2.5 hours of cello. So

3h violin - 2.5h cello

9h violin - xh cello

$3x = 9*2.5$

$x = 7.5$

He practiced 7.5 hours of cello, the same as Nina.

For every 3 hours Nina spends practicing the viola she practices the cello for 2 hours. So:

3h viola - 2h cello

xh viola - 7.5h cello

$2x = 3*7.5$

$x = 7.5*1.5$

$x = 11.25$

Nina practiced the viola for 11.25 hours last week.
