Answer:
14.9
Step-by-step explanation:
50-5.03 = 44.97
44.97 ÷ 3 = 14.99
There is 180deg in a half circle, and 360deg in a full circle. complementary angles complete a half circle perfectly.
angle z is complementary to 111deg.
z= 180 - 111= 69deg
z= 69deg
There are 360 total degrees in the figure because it makes one total revolution.
y= 360- 69- 94- 88
y= 109deg
Check - 109 +69 +94 +88= 360
Answer:
78 girls
Step-by-step explanation:
Ratio is 3:4, so that means the total number of 182 can be divided into 7 parts. 182 divided by 7 is 26, so each part is 26. The ratio of girls is 3, so 3 times 26 is 78. You can check this by putting (3*26)/(4*26) simplifies to 78/104 to 3/4 which is the right ratio
Step-by-step explanation:
If 200 g fertiliser required for 8 m^2 then for 1m^2 we'd need 25 g of fertiliser
(i) 14×25 = 350 g fertiliser would be needed for 14 m^2 land
(ii) 450÷25 = 18 m^2 land could be fertilised with 450 g fertiliser
Answer:
4.8, 135, 0.2822, 0.024
Step-by-step explanation:
4*1.2=4.8
7.5*18=135
0.34*0.83=0.2822
