rounding to nearest 10 to any number follow these rules
1. if number ends 0 , 1 , 2 ,3 4 , 5 take number down to nearset multiple of 10
2. if number ends with above 5 take the upper number multiple of 10
so here
413 + 35.6 + 998.5 + 376 + 85.3
= 410 + 40 + 1000+ 380 + 90
= 1920
Lets say a number is x
the expression is
x ≥ 90
Answer:
An obtuse triangle can not have more than one angle measured greater than 90.
Step-by-step explanation:
Obtuse triangles have 2 acute angles (less than 90 degrees) and 1 obtuse angle (greater than 90).
The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called <em>corresponding angles</em>. When the two lines are <em>parallel</em>, the corresponding angles are <em>equal</em>.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, <em>the corresponding angles will be the same</em>.
Since the first corresponding angle is 72°, the second angle <em>x </em>will be 72° as well. The correct answer is: x = 72° Option (D).
Use equation C1M1+C2M2=CM
C1=15%, M1=10000 mg (starting ointment)
C2=0% M2=to be found (diluent)
C=12% M=M1+M2 (product)
Solve for M2
0.15*10000+0*M2 = 0.12(10000+M2)
M2=(0.15-0.12)*10000/0.12=2500 mg
Answer: 2500 mg of diluent is required.
