Answer: pretty sure it will be .5
If you have a whole number move the number of exponents in 10 and move left. If you have a decimal, and the 10 is negative exponent, move to the write.
-(4/5)*(3/7)*(15/16)*(-14/9) [two negatives make one positive]
=(4*3*15*14)/(5*7*16*9) [simplify 4/16]
=(3*15*14)/(5*7*4*9)
=(3*3*14)/(7*4*9)
=(14)/(7*4)
=(2)/(4)
=1/2
Hence, this question is out of my expiurtise ask again
Answer:
B. 455
Step-by-step explanation:
The order in which the toppings are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
3 toppings from a set of 15. So
455 3-topping sundaes can be made.
