2. it can't have three because one of them is a right triangle do D doesn't add up. It can't have 0 because an obtuse angle plus a right angle would go over 180 degrees. So, the most it can have is 2 acute for example 90(right angle) 30(acute) and 60 (acute) is a possible answer. Also, a right angle can only have two acute angles since an obtuse angle would put it over 180 which was already stated
Given The equation -2x(-2.8)=24, we are trying to find the value of X.
The first step is to devide both sides by 2
·-x(-2.8)=12
The next step would be to distribute.
·2.8x=12
Next we devide both Sides By 2.8 to get our final answer
·X=4.28
Although your choice answers are unclear, the answer is X=4.
-I hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
Answer:
f(x)=x/7
Step-by-step explanation:
f(x)=7x
y=7x
x=7y (switch y and x for inverse)
x=7y (isolate y)
x/7=y
The inverse of f(x)=7x is f(x)=x/7
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:
Square both sides to get rid of the square root:
Now plug the known value of the speed to find the distance:
So the closest answer is the last one: d=0.155km
