Answer:
B
Step-by-step explanation:
Note that the absolute value always returns a positive value, that is
| - a | = | a | = a, thus
| 34 - 49 | = | - 15 | = 15 and
| 17 - 24 | = | - 7 | = 7
The sum simplifies to
+
Before adding the fractions must have a common denominator, thus
+
= + = → B
Answer:
Step-by-step explanation:
From the diagram,
AO=OC=16 units, all radii of a circle are equal.
BO=OC+BC
BO=16+18
BO=34
A tangent to a circle will always meet the radius at right angles.
We use the Pythagoras Theorem to obtain:
Take positive square roots to get:
<span>if they already have 200 then the "must collect" 800 to reach 1000</span>
180=132+21+x
180=153+x
-153 -153
x=27
