First, write out all the prime factorisation of 30, 45, and 70.
30: 2*3*5
45: 3*3*5
70: 2*5*7
Then, find a number that all three numbers have in common; which is 5. So, 5 is the greatest common factors of 30, 45, and 70.
Ricks sporting good:
100% - 20% = 80% so the basketball is on sale for 80% of the original price so 24.95 x 0.80 = 19.96 ( sale price)
Sports Expert:
100% - 25% = 75%
so the basketball is on sale for 75% of the original price 25.80 x 0.75 = 19.35 (sale price)
19.35 is less than 19.96 so the better deal is from Sports Expert
Hey there!
The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.
Let me know if you are still confused and need a better explination :)
Have a great day!
Answer:
13
Step-by-step explanation:
(n-2) +(n-1) +n =3n-3=36
n=(36+3)/3=13
Consecutive integers are 11,12 and 13
Answer:
children = 177, adults =215
Step-by-step explanation:
im too lazy to write but solve this with a systeme
x(children),y(adults)
x+y=392
x=392-y
2.5y+1.25x=758.75
2.5y+1.25(392-y)=758.75
2.5y+490-1.25y=758.75
490+1.25y=758.75
1.25y=758.75-490
1.25y=268.75
y=268.75/1.25
y=215
x=392-215=177(number of kids)
