My previous answer was incorrect, sorry for that... the correct answer would be 358,800
Answer:
It invaluatesa to 1
Step-by-step explanation:
sin25 ∘cos65 ∘+cos25 ∘sin65 ∘=sin25
∘ sin(90 ∘−65 ∘)+cos25
∘cos(90 ∘−65 ∘ )
=sin25 ∘
sin25 ∘ +cos25 ∘cos25 ∘
=sin 2 25 ∘+cos 2 25 ∘=1
hope this helped you!
Answer:
x = 27/10 or x = 2.7
Step-by-step explanation:
Step 1: Get rid of the denominator.
LCD of 4 & 3: 12
Multiply both sides by 12.
12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)
Reduce the numbers.
3 ( 2x - 1) + 4x = 24
Step 2: Distribute.
6x - 3 + 4x = 24
Step 3: Collect like terms.
6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)
10x = 27
Step 4: Solve for x.
Multiply both sides by 10.
10x / 10 = 27 / 10 (the 10 cancels out)
x = 27 / 10 or x = 2.7
Answer: x = 27 / 10 or x = 2.7
144 the circumference is 360 because it’s a circle, 360/5=72 72(2)=144
Maybe (10)(3/5)=6
The parentheses is multiplication
