Answer:
150°
Step-by-step explanation:
Consider OACB,
Here <CAO =<CBO= 90° ( As they are tangents)
<ACB= 30°
Now, <CAO +<CBO+<ACB+x= 360°
90°+90°+30°+x= 360°
x= 150°

Let us assume the weight of the red snapper caught by Dana = X
The weight of the tuna caught by Jason was 3 times the weight of the snapper caught by Dana. Then,
Weight of the tuna caught by Jason = 3X
Weight of the sailfish caught by Murray is 12 times the weight of the red snapper caught by Dana. Then,
Weight of the sailfish caught by Murray = 12X
The combined weight of the 3 fishes caught = 208 pounds.
Then,
X + 3X + 12X = 208
16X = 208
X = 208/16
= 13
So the red snapper weighed 13 pounds
The weight of the tuna caught by Jason = 3X
= 3 * 13
= 39
So the tuna weighed 39 pounds.
Count the squares
6 x 3.5
Area = 6 x 3.5
Area = 21
Perimeter = 6 + 6 + 3.5 + 3.5
Perimeter = 19
Answer:
D. 296 square inches
Step-by-step explanation:
The surface area of a prism is the total area of all its faces.
A triangular prism has three rectangular faces and two triangular faces.
As all 3 sides of the triangle face of this prism are equal, each of the 3 rectangular faces are also equal in area.
<u>Formulae</u>
- Area of a triangle = 1/2 x base x height
- Area of a rectangle = width x length
From inspection of the diagram:
⇒ Area of a triangle = 1/2 x 8 x 7 = 28 in²
⇒ Area of a rectangle = 8 x 10 = 80 in²
<u>Total surface area</u>
Total surface area = 3 rectangle areas + 2 triangle areas
= (3 x 80) + (2 x 28)
= 296 in²
Answer:2.4km/hr
Step-by-step explanation:
Speed = distance/time
Speed =4.6/2
