Answer:
x = 6
∠B = 126
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x + 78°
∠B = 2x + 114°
8x + 78° = 2x + 114°
8x - 2x = 114 - 78
6x = 36
x = 36/6
x = 6
plugin x into ∠B = 2x + 114°
∠B = 2x + 114°
∠B = 2(6) + 114°
∠B = 126
Answer:
37÷2=18.5... radius is half the circumference
A) p + n + d = 18
B) .01p + .05n + .10d = 1.14
C) 2p = d
Substituting C) into A)
A) p + n + 2p = 18 equals
A) 3p + n = 18
Substituting C) into B)
B) .01p + .05n + .10 *2p = 1.14
B) .01p + .05n + .2p = 1.14
B) .21p + .05n = 1.14
Taking equation A)
A) 3p + n = 18 and multiplying it by -.05
A) -.15p -.05n = -.90 Then adding this to B)
B) .21p + .05n = 1.14
.06p = .24
Therefore there are 4 pennies.
(I'll leave it to you to determine the nickels and dimes.)
**************************************************************************
Oh what the heck, I'll finish it for you.
Looking at equation C)
C) 2p = d
We know there are 4 pennies so there are:
2 *4 = eight dimes
Looking at Equation A)
A) p + n + d = 18 we can fill in the pennies and the dimes:
A) 4 + n + 8 = 18
Therefore, there are 6 nickels.
Answer:
Step-by-step explanation:
No
Because the value of domain is repeat
Like (0,1) and (0,3)
Answer:7.6°
Step-by-step explanation:
Using sine formular
sinA/a =sinB/b
sin33/x = sin90/14
cross multiply
xsin90 = 14sin33
Divide bothside by sin90
x = 14sin33 / sin90
x= 7.6249 / 1
x = 7.6° to the nearest tenth.
