Answer:
14.
Step-by-step explanation:
From the question given, we obtained the following information:
When angle θ = 60°
Adjacent = 7
Hypothenus = s
When angle θ = 30°
Opposite = 7
Hypothenus = s
We can use any of the above to determine the value of 's'.
Here, we shall consider when angle θ is 60°.
Cos θ = Adjacent /Hypothenus
Angle θ = 60°
Adjacent = 7
Hypothenus = s
Cos θ = Adjacent /Hypothenus
Cos 60° = 7/s
But Cos 60° = 1/2
1/2 = 7/s
Cross multiply
s = 2 x 7
s = 14
Therefore, the value of 's' is 14

Step-by-step explanation:
To find how much paper for the model, you will use the formula for area of a square and area of a triangle.
A = bh
7.2 x 7.2
A = 51.84 cm²
A = 1/2bh
1/2 x 7.2 x 6
A = 21.6 cm²
21.6 cm² x 4 = 86.4 cm²
86.4 + 51.86=138.3
You will need 138.3 cm² of paper.
Answer:
0.028
Step-by-step explanation:
divide 1.680/60
Step-by-step explanation:
area of the rectangle : L×B = 2.1×1.2 = 2.52m².
diameter = 1.2 m, radius = 1.2/2 =0.6m
area of the semi-circle : πr²/2 = 22/7×0.6×0.6/2 = (22×0.6×0.6)/(7×2) = 7.92/14 = 0.565m².
Therefore, total area of the door : (0.565+2.52)m² = 3.085m².

Step-by-step explanation:
Jack Bag Full of Marbles:
5 Green Marbles
4 Red Marbles
6 Blue Marbles
Jack takes one marble and then does not replace the marble in the bag.
Question:
What is the probability of grabbing a white marble on the first pull?
================================================================
We Know that Jack have Green, Red, and Blue Marbles..
And It has no white Marbles.
Hence, the answer is 0.
