Answer:
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:
Then we have the following expression:
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
Complete factorization of 28 gives an answer of 7 x 2 x 2. 7 on the other hand, has no other factor other than 7 and 1. The least common multiple of these numbers is the least number that can be divided by 28 and 7. The answer is 28.
Answer:
Arc length of arc BC is 6.98 units or roughly 7 units.
Step-by-step explanation:
First recall that the formula for the circumference of a circle is C = 2πr, where r is the radius. Here the radius is 4 units. so the circumference of the (entire) circle is C = 2π(4 units) = 8π units.
The central angle for the arc shown in yellow is 100 degrees. The length of this arc is a fraction of C as found earlier:
100
------- * 8π units = 800π/360 units, or 6.98 units (about 7 units).
360
Arc length of arc BC is 6.98 units or roughly 7 units.
1. is 196 all you had to do was divide the percentages
We'll be assuming this is with simple interest.
now, a year has 12 months, thus in 18 months there are 18/12 years.
