3 cm on the map represents 31.5 km in reality.

3cm : 31.5 km

1cm : 31.5/3 km

1cm : 10.5km

So the scale on the map is 1cm represents 10.5 km.

Area = base × height

Base = 2. 3cm

height = 4. 9cm

Area = 2. 3 × 4. 9

Area = 11. 27 cm²

Thus, the area of the figure is 11. 27 cm²

O is the centre of the circle, EF is a tangent, angle BCE=28 degrees, angle ACD=31 degrees.

Yuki888 [10]

Answer:

a. 28˚

b. 76˚

c. 104˚

d. 56˚

Step-by-step explanation

a. because angle between tangent and chord is equal to the angle(s) in alternate segment.

b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚

c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚

d. 28*2=56˚ because angles at circumference are half angles at centre

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.

aliina [53]

Answer:

A. 14040 cubic inches

B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

V = LWH

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

<em>Additional comment</em>

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

Which graph represents the compound inequality? –3 < n < 1

Alinara [238K]

<span>the graph that represents the compound inequality –3 < n < 1 is the straight line from -3 to 1 in which there is a hollow circle in the -3 point and in the 1 point. This is because < means that the possible values of n is only greater than -3 exluding -3 and less than -1 excluding -1</span>
