Answer:

<1 = 78

Step-by-step explanation:

<1 and 102 are supplementary angles so they add to 180 degrees

<1 + 102 = 180

Subtract 102 from each side

<1 + 102 -102 = 180-102

<1 = 78

Answer:

A burrito costs $8, while a taco costs $6.

Step-by-step explanation:

Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:

3B + 4T = 48

3B = 48 - 4T

6B + 2T = 60

6B = 60 - 2T

3B = 30 - 1T

30 - 1T = 48 - 4T

30 = 48 - 4T + 1T

30 - 48 = -3T

-18 = -3T

-6 = -T

6 = T

3B + 4x6 = 48

3B + 24 = 48

3B = 24

B = 24/8

B = 8

6x8 + 2x6 = 60

48 + 12 = 60

60 = 60

Thus, a burrito costs $ 8, while a taco costs $ 6.

F(x)=9x^2 <br><br> g(x)= sqrt 12-x/3<br><br> (f o g)(-4)

Slav-nsk [51]

$f(x)=9x^2 \\ g(x)=\frac{\sqrt{12-x}}{3} \\$ So,first step is to write $(fog)(-4)) =f[g(-4)] \\$

Now we start from inner paranthesis ,we need to first find value of $g(-4) =\frac{\sqrt{12-(-4)}}{3}\\ =\frac{\sqrt{12+4}}{3}\\
=\frac{\sqrt{16}}{3}\\
=\frac{4}{3}\\
(fog)(-4)) =f[g(-4)] =f(\frac{4}{3}) =9(4/3)^{2} =9*(16/9) =144/9 =16$
