We know that
360°/12 hour-----------> 30°/hour
<span>Central angle at 4 .00 is 120 degrees
the radius of a clock is 6/2-----> r=3 in
length of a circumference=2*pi*r-----> 2*pi*3----> 18.84 in
the minor arc at 4 .00 is for a central angle of 120</span>°
so
if 360° (full circle)---------> has a length of 18.84 in
120°----------------------> X
X=120*18.84/360-------> X=6.28 in
the answer is
6.28 in
Answer:
I would say the TRIANGLE because it has none of the lines that a symmetry has.
4 loads of stone ... 2/3 ton
1 load of stone ... x ton = ?
If you would like to know the weight of 1 load of stone, you can calculate this using the following steps:
4 * x = 2/3 * 1
4 * x = 2/3 /4
x = 2/3 / 4
x = 2/12 = 1/6 ton
The correct result would be 1/6 ton.
Answer:
A
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 4x - 8 - (2x - 5) ← distribute parenthesis by - 1
= 3x² + 4x - 8 - 2x + 5 ← collect like terms
= 3x² + 2x - 3 → A
Answer:
99 miles
Step-by-step explanation:
Length of the trace 444 miles
The couple drove that distance in four days doing as follow:
Lets call x the miles per day they drove
first day x miles
Second day 8 + x miles
Third day 8 + 8 + x miles
fourth day 8 + 8 +8 + x miles
Then we get the equation:
x + ( 8 + x ) + ( 16 + x ) + ( 24 + x ) = 444
Solving for x
4x + 48 = 444 4x = 444 - 48 4x = 396
x = 99 miles
