Answer:
70sqrt(6)
Step-by-step explanation:
7×(600)^½
7×[6^½ × 100^½]
7× 6^½ × 10
70×6^½
70sqrt(6)
sqrt: square root
2X-2=2X+9
Add 2
2X=2X+11
Subract 2X
0= 11
This has no solution to this problem
This is quite an easy question rather.
6 is for for 10yrs and 26 from 20yrs because you simplisticly add ten or twenty
Answer:
a + c = 30
8a + c = 100
a=10, c= 20
Step-by-step explanation:
cost = 8a + 1c since it is 8 dollars for adult and 1 for child where a is the number of adults and c is the number of children
a+c = 30 since we know that 30 adults and children went
100 = 8a + 1c and it cost 100 dollars
Let c =30 -a
100 = 8a + (30-a)
100 = 7a +30
Subtract 30 from each side
70 = 7a
Divide by 7
10 =a
Then a+c = 30
10+c = 30
c = 30-10
c = 20
The height of the cone is 18.79 ft.
Step-by-step explanation:
Given,
The slant height (l) of the cone = 17 ft
The diameter = 16 ft
So, the radius (r) = 8 ft
To find the height (h) of the cone.
Formula
By Pythagoras theorem,
Perpendicular²+ base² = height²
Now,
Height² = 17²+8²
= 289+64
= 353
h = 
- 18.7888 = 18.79 (approx)
Hence,
The height of the cone is 18.79 ft.
