Answer: Shane collected more than 911 cans
Step-by-step explanation:
S is the number of cans that shane collected.
A is the number of cans that Abha collected.
We know that:
together collected more than 2000 cans
A + S > 2000
Abha collected 178 more cans that Shane:
A = S + 178
Now, we can replace this equation in the inequality and get:
A + S > 2000
S + 178 + S > 2000
2*S > 2000 - 178 = 1822
S > 1822/2 = 911
This means that shane collected more than 911 cans.
Use algebra for such problems
let, Angle COD = x
Angle KOD = y
Angle KPC = z
Given ,. x - y = 61° ( Equation 1 )
x - z = 53° ( Equation 2 )
Subtract 1st equation from 2nd and you'll get :
z - y = 8° ( Equation 3 )
Now since , x + y + z = 180° ( Equation 4 )
Add Equation 3 to Equation 4 and you'll get
x + 2z = 188° ( Equation 5)
From Equation 2 we know that , x -z = 53°
or, x = 53° + z ( Equation 6 )
Put this value of 'x' in Equation 5 and solve for z. you'll get :
(53° + z) + 2z = 188°
or
3z = 188 - 53 = 135°
solving for z we get
z = 45°
put this value of z in Equation 5
x + ( 2 x 45° ) = 188°
or
x = 188° - 90° = 98°
hence , Angle COD = 98°
Oh my, ummm if u go on slander and search that book name then type that page number it will give u all the answers, and the answers are probably at the back of the book <3
Answer:
690 sq in
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base
The triangular base has an area of
B = 1/2bh 1/2(5)(12) = 30
LA = ph where p is the perimeter of the base and h is the height of the prism
LA = (12 + 5 + 13)(21) = 30(21) = 630
SA = 630 + 2(30) = 630 + 60 = 690 sq in
