Answer:

16.6 in

Step-by-step explanation:

The volume (V) of a pyramid is

V = \frac{1}{3} area of base × h

where h is the perpendicular height and area of base = 14² = 196

here V = 980, so

\frac{1}{3} × 196h = 980 ( multiply both sides by 3 )

196h = 2940 ( divide both sides by 196 )

h = 15

Consider the right triangle formed by the height h from the vertex to the midpoint of the base and the slant height (s) ← the hypotenuse

Using Pythagoras' identity in the right triangle

s² = 15² + 7² = 225 + 49 = 274 ( take the square root of both sides )

s = \sqrt{274} ≈ 16.6

Answer:

1. m∠B=110°

2. 560 cm3

3. Numerical data

4. 2000 cm3

5. 50%

Step-by-step explanation:

1. The explanation of part 1 is given in the attachment.

2. Given dimensions : 10 cm, 8 cm, and 7 cm.

Let Length of cuboid =10 cm

breadth/width of cuboid  =8 cm

height of cuboid = 7cm

Volume of cuboid = length *width* height

=( 10 *8*7) cm3

=(560) cm3

3. Age, Birth date  and weight are the types/examples of "<u>Numerical Data"</u> because these all are describe in terms of numeric values.

4. 1 liter = 1000 cm3   or   1 cm3 = 0.001 liter

1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3

1 dm3 =1000 cm3

0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3

Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 = <u>               </u> cm3

1500 cm3 + 350 cm3 +150 cm3 = <u>2000</u> cm3

5. If A=(1/2)B, then B : A = <u>50</u> %

Ratio: B : A

B : (1/2) B

1: (1/2)

50 % (The value of A is half of the value of B)
