So first you would evaluate the power making the 4^3=64 then keep the rest of the problem the same.... then add the numbers 64+8 since their the whole numbers and that would equal 72 so now the problem should be 72-9/y. After that you write all the numerators above the common denominator making the final answer to be 72y-9/y
Answer:
b = 33 miles
Step-by-step explanation:
The illustration forms a right angled triangle. The opposite side of the triangle is where we are looking for . The adjacent side is the radius 4000 miles.
5280 ft = 1 mile
735 ft = ? miles
cross multiply
735/5280
miles = 0.13920454545 miles
The hypotenuse side is the height of the building + 4000 miles = 0.140 + 4000 = 4000.14 miles
using Pythagoras theorem
c² = a² + b²
c = 4000.14
a = 4000
4000.14² = 4000² + b²
b² = 4000.14² - 4000²
b² = 16001120.0196 - 16000000
b² = 1120.0196
b = √1120.0196
b = 33.4666938911
b = 33 miles
The probability is 1/5, or 20%.
Explanation there are only 2 numbers on the die divisible by 4, those being 4 and 8, therefore 2/10 which simplifies to 1/5 or 20% I hope this helps :)
Answer:
.95(1.09m+2.79n)=candys bill
Step-by-step explanation:
5% off is like having 95% of the full price so .95=95%
Answer:
x = 2/3
DF = 10
scale factor of ΔDEF to ΔXYX is 1:3
Step-by-step explanation:
DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:
6x+6/30 = 8/24
simplify 8/24 to be 1/3
6x+6/30 = 1/3
cross-multiply:
3(6x+6) = 30
18x + 18 = 30
18x = 12
x = 12/18 or 2/3
