Answer:

x = 21

y = 7√3

Step-by-step explanation:

One of the sides is 21 (clue from the provided answers).

Using the Pythagorean theorem:

(14√3)² = 21² + side²

588 = 441 + side²

side² = 147

side = 7√3

Now we have our three sides but, which one is x and which one is y?

try x = 21:

cos 30 = 21/(14√3)

0.8660 = 21/(14√3)

0.8660(14√3) = 21, yes, then x = 21

16th term in the geometric sequence 1024, -512, 256, ....

tresset_1 [31]

Answer:-1/32

Step-by-step explanation:

First term=a=1024

Common ratio=r=-512/1024

r=-1/2

Using them formula

Tn=a x r^(n-1)

T16=1024 x (-1/2)^(16-1)

T16=1024 x (-1/2)^15

T16=1024 x -1/32768

T16=-1024/32768

T16=-1/32

What is the solution to the system of equations? y = A system of equations. Y equals StartFraction 2 over 3 EndFraction x plus 3

Sauron [17]

Answer:

The solution to the given system of equations is (-2, $\frac{5}{3}$ )

Therefore the values of x and y are x=-2 and $y=\frac{5}{3}$

Step-by-step explanation:

Given equations can be written as

$y=\frac{2}{3}x+3\hfill (1)$

$x=-2x+3x=-2\hfill (2)$

Solving equation(2) we get

x=-2

Substitute x=-2 in equation (1) we get

$y=\frac{2}{3}(-2)+3$

$=-\frac{4}{3}+3$

$=\frac{-4+9}{3}$

$=\frac{5}{3}$

Therefore the values of x and y are x=-2 and $y=\frac{5}{3}$

The solution to the given system of equations is (-2, $\frac{5}{3}$ )

Thirty percent of the people refused to work and just sat around. if 1400 people worked, how many just sat around?

Nezavi [6.7K]

30% can also be written as .3, which is easier to use in this case.

To find how many just sat around, multiply the number of people by the percentage of how many just sat around.

1400*.3=420
