Distance hour hand travel in 5 hours is 20.94 inches.
<h3>
What is a diameter?</h3>
- A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
- It is also known as the circle's longest chord.
- Both definitions apply to the diameter of a sphere.
To find the distance hour hand travel in 5 hours:
- Let's say the hour hand completed one full round around the clock.
- If this was the case, it would have been 2
×8 inches around. - We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2×8×( 5/12 ).
- Distance hour hand travel is 20.94 inches.
Therefore, the distance hour hand travel in 5 hours is 20.94 inches.

Answer:
$150
Step-by-step explanation:
25x4=100
100+50=150
so she has $50 to spend on other things
i dont know if this is what its asking or how
Answer:
x = 7
Step-by-step explanation:
There is a total of 180 degrees in a triangle. To solve you add the other angles and set = to 180 then solve for x
180 = 33 + 90 + 7x +8
172 = 33 + 90 + 7x
139 = 90 +7x
49 = 7x
7 = x
Alright, let's do all of these (though this is a bit long).
1.
The constant is 1.8. All other values are coefficients to variables, which as the name implies will change.
2.
1 hour is 60 minutes, 1 minute is 60 seconds.
So, 4.2 *60 *60 = 15120 seconds.
3.
<span>−5x−4(x−6)=−3-5x-4(x-6)=-3
Let's move all x to one side, and all other numbers to another.
-5x-4(x-6)=-3-5x-4(x-6)=-3
x can be any value you want, if you actually solve this you'll only end up with -3 = -3, which is correct, of course.
Let me show you:
</span><span>−5x−4(x−6)=−3-5x-4(x-6)=-3
+5x +4(x-6) +5x +4(x-6)
-3 = -3
The value of x is irrelevant, then. X can be any real number.
4.
I'm going to assume it was an error in printing with this? If not please correct me.
m=a+2b(or b2)
subtract 2b from each
a=m-2b
(This question seems kind of odd. We should probably address this in the comments.)
5.
</span><span>5(x−2)<−3x+6
Move all x to one side, numbers to other.
5x-10<-3x+6
+3x +3x
+10 +10
8x<16
/8
<span>x < 2
</span>6.
y-3=3(x-5)
alright, to find zeros set one variable to zero and solve
x first
-3=3x-15
+15 +15
3x=12
/3
x=4
x-int is (4,0)
now y
</span>y-3=3(0-5)
y-3=-15
+3 +3
y=-12
so y-int is (0,-12)
i've got to sleep now so i'll do the rest tomorrow. Sorry for the incomplete answer.
