Answer:
= Sh. 2281.50
Step-by-step explanation:
Area of the path;
(126 × 2.5 ) + (2.5 × (48 - (2.5×2)
= 315 + (2.5 × 43)
= 315 + 107.5
= 422.5 m²
But; the cost of graveling is sh 5.40 per square meter
Therefore; The cost of graveling the whole path;
= 422.5 × 5.40
<u>= Sh. 2281.50</u>
Hello,
We are going to used the theorem of Thalès.
||v||=√(3²+(-2)²)=√13
k*√13=10==>k=10/√13
w=k.v=10/√13<3,-2>
Answer:
22
Step-by-step explanation:
x = number of bats bought
y = number of gloves bought
20x + 12y = 1040
25x + 16y = 1350
multiply equation 1 by 4 and equation 2 by 3 and then subtract equation 2 from equation 1 :
80x + 48y = 4160
- 75x - 48y = -4050
-----------------------------
5x + 0 = 110
5x = 110
x = 22
just in case also to check how many gloves were bought :
20x + 12y = 1040
20×22 + 12y = 1040
440 + 12y = 1040
12y = 600
y = 50
so, 50 gloves were bought.
