6 0

Answer:

11. x=10, y=14.1421356237

12. x=12.124355653, y=14

Step-by-step explanation:

11. Use tan and pythagorus

tanA=opposite/adjacent

tan45=x/10

10(1)=x

x=10

a²=b²+c²

y²=x²+10²

y²=10²+10²

y²=100+100

y=√200=14.1421356237

12. Use tan and pythagorus

tanA=opposite/adjacent

tan30=7/x

0.57735026919x=7

x=7/0.57735026919

x=12.124355653

a²=b²+c²

y²=x²+7²

y²=12.124355653²+7²

y²=147+49

y=√196=14

4/3x + 1/6x = 36 (solve for x please help I have no idea what it is!!!!!!!
ElenaW [278]

Answer:

x = 24

Step-by-step explanation:

\frac{4}{3}x + \frac{1}{6}x = 36

Make the denominator the same by multiplying the first fraction by 2 to make both denominators 6.

\frac{8}{6}x + \frac{1}{6}x = 36

Now we can calculate the numerators and keep the denominators the same.

\frac{9}{6}x = 36

Find x.

\frac{6}{6}x = \frac{6}{9} × 36

x = 24

(-5+2)•(-1/2)<br><br> I don’t know how to do this problem. Would anyone be able to assist? Thanks!
SpyIntel [72]

Answer:

3/2 or 1 1/2 or 1.5

Step-by-step explanation:

first do the equations in each parentheses:

(-5+2) = -3

(-1/2) = -1/2

then multiply both sides:

-3 • -1/2 (which is the same as -3 • -1 over 2)

= 3/2 or 1 1/2 or 1.5
