The answer is C
short explanation: the two triangles are congruent so that would make BD equal to AC and if AC is 6 then BD is 6
hope this helps
Answer:
3.47
Step-by-step explanation:
since the third decimal is less than 5 then it doesn't carry over to the 7 thus it remains 7.
You find the least common multiple of the two denominators, then you multiply whatever you multiplied to the denominator to the numerator to get to the LCM.
ex:
3/4 + 2/3 --> 9/12+ 8/12= 17/12

Answers:</h3>
angle FHG = 42 degrees
angle GHI = 100 degrees
=========================================================
Explanation:
FHI is the largest angle. It is split into two pieces FHG and GHI which have measures of (3x+6) and (9x-8) degrees respectively.
Put another way, those two smaller angles (FHG and GHI) combine to form the larger angle (FHI)
This is the angle addition postulate.
------------------
(angle FHG) + (angle GHI) = angle FHI
(3x+6) + (9x-8) = 142
3x+6+9x-8 = 142
(3x+9x) + (6-8) = 142
12x - 2 = 142
12x-2+2 = 142+2 ... adding 2 to both sides
12x = 144
12x/12 = 144/12 .... dividing both sides by 12
x = 12
------------------
Use that x value to find the angles we're after
angle FHG = 3x+6 = 3*12+6 = 36+6 = 42
angle GHI = 9x-8 = 9*12-8 = 108-8 = 100
Note how
(angle FHG) + (angle GHI) = 42 + 100 = 142
which is the measure of angle FHI. This confirms the answers.
Answer:
25
Step-by-step explanation:
Given the equation :
T = 200 - 4R
T = amount of money left ; if T = $100
R = number of rides
$100 = 200 - 4R
$100 - $200 = - 4R
-$100 = - 4R
R = 100/ 4
R = 25
25 rides
