We know that ON = 80 cm and ∠ O = 37°.
cos 37° = 4/5
Adjacent / Hypotenuse = cos∠O
80/OP = cos 37°
80/ OP = 4/5
OP = 80 : 4/5 = 80 · 5/4 = 100
Answer:
d. 100 cm.

Actually Welcome to the Concept of the Ration and Percentage,
To get the Adams rake,
let's calculate 5% of 357 ltrs.
therefore, (5/100)* 357 = 17.85 ltrs
let's subtract the 5 % value from Tapiwa rake,
==> 357 - 17.85 == 339.15
hence the Adams rake is 339.15 ==> round off ==> 339 litres.
Answer:
A
Step-by-step explanation:
square: 10² = 100
Circle: π*5² = 3.14*25 = 78.5
In the squqre not in the circle: 100-78.5 = 21.5
Answer:
= 49
Answer.
Step-by-step explanation:
Solution:-
Length of the road = 5 miles
Distance between every two streetlights = 1/10 miles
Total number of streetlights placed on the new road = 5 ÷ 1/10
= 5*10
= 50 streetlights
As there is already a streetlight at the beginning of the new road, so the number streetlights will be = 50 - 1
