Answer:
for the -4-2y=28
Step-by-step explanation:
you would add 4 to the other side to be -2y=28+4 then divide the whole equation by -2 so it would be y = -14 - 2
that all i know
Answer:
Area of the trapezium = 30
Step-by-step explanation:
a = 14
b = 4
h= 5
Area of trapezium = ( a + b) h = (14+4) 5
= x 18 x 5 = 6 x 5 <em> [I solved </em><em> and 18]</em>
= 30!
Answer:
F 6
Step-by-step explanation:
3 / (1/2)
When dividing by a fraction flip it over and multiply
3 * (2/1) = 6/1 which is just 6
Answer:
The curved surface area of the cone is approximately 329.9 cm²
Step-by-step explanation:
The parameters of the right circular cone are;
The radius of the cone, r = 7 cm
The slant height of the one, l = 15 cm
The curved surface area of a cone, CSA = π·r·l
Therefore;
CSA = π × 7 cm × 15 cm = 105·π cm² ≈ 329.9 cm².
Answer:
Step-by-step explanation:
x = 10sqrt(2)*cos(60) = 5sqrt(2) = 7.07 approx.
y = 10sqrt(2)*sin(60) = 10sqrt(2)*sqrt(3)/2 = 5sqrt(6)=12.25 approx.
