Ade has two similar scale models of the same pyramid. The first model has a
height of 5 inches and a surface area of 80.9 square inches. The linear dimensions
of the second model are each increased by a common factor so that the height of
the second model is 15 inches. To the nearest tenth of a square inch, what is the
surface area of the second model?

Please help!

Answers

Answer: 242.7 square inches

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

The first model has a height of 5 inches and a surface area of 80.9 square inches:

The proportion is : height/ surface area= 5 in / 80.9 in2

For a height of 15 inches

15 in/ x in2

So:

5/80.9 = 15/x

x= 15/ (5/80.9 )

x= 242.7 square inches

The area of a 2D form is the amount of space within its perimeter. The area of the composite figure is 249 cm².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the composite figure can be written as,

Area = ABCG + DEFG =  (4×10.5) + (11.5×18) = 42+207 = 249cm²

Hence, the area of the composite figure is 249 cm².

baseball card that was valued at $200 in 1980 has intreased in value by 7% each year. Write a function to model this situation, then find the
value of the card in 2016.

Answers

(36*.07)+200 and 475

The function to represent this situation is A = P( NR+1 ) and the amount in 2016 is $704.

What is simple interest?

"Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same".

For the given situation,

Principle, P = $200

Rate of interest, R = 7% = 0.07

Number of years from 1980 to 2016, N = 36

The total amount in 2016 can be modeled as the equation,

[tex]A=P(NR+1)[/tex]

⇒ [tex]A = 200[(36)(0.07)+1][/tex]

⇒ [tex]A=704[/tex]

Hence we can conclude that the function to represent this situation is     A = P( NR+1 ) and the amount in 2016 is $704.

1. On a quiet day without many witnesses, a 4.5 ft victim is shot by a sniper that
was in a tower 780 ft away. If the angle of elevation is 48° from the victim, at
what vertical distance did the sniper shoot from?

Answers

Answer:

The sniper shoot from 870.775 feet vertical distance.

Step-by-step explanation:

Refer the attached figure

Height of victim = AB = 4.5 ft.

Distance between tower and victim BC = 780 feet

The angle of elevation =[tex]\angle DAE = 48^{\circ}[/tex]

Let DE be x

AB = CE = 4.5 feet

BC =AE = 780 feet

Height of tower = DE+CE=x+4.5

In ΔDAE

[tex]\frac{Perpendicular}{Base}=Tan\theta\\\frac{DE}{AE}=Tan 48^{\circ}\\\frac{x}{780}=1.11061\\x=1.11061 \times 780\\x=866.275[/tex]

Height of tower = DE+CE=x+4.5=866.275+4.5=870.775 feet

Hence  the sniper shoot from 870.775 feet vertical distance.

Answers

Answer:

P(Both) = 781/10000

Solution:

P(T) = 71/100

P(6) = 11/100

P(Both) = P(T) * P(6)

(Both) = 71/100 * 11/100

P(both) = (71 * 11) / 10000

P(Both) = 781/10000

T = 71 times

5 being rolled = 11

Substitution and solution.

P(T) = 71/100

P(6) = 11/100

P(Both) = P(T) * P(6)

P(Both) = 71/100 * 11/100

P(both) = (71 * 11) / 10000

P(Both) = 781/10000
