You are 5 feet tall and cast an 8-foot shadow. A lamppost nearby casts a shadow that is 20 feet. Which equation can you use to solve for the height (h) of

Answers

Answer 1
Answer:

Answer:

Height of lamppost would is 12.5 feet.

Step-by-step explanation:

We are given a 5 feet tall boy form shadow with 8 foot.

As we know height is directly proportional to shadow length.

\therefore h\propto s

h=ks

where, h is height of boy, k is constant of proportionality and s is shadow length.

when h=5 , s=8

5=8k

k=(5)/(8)

We need to find height when shadow length is 20 feet.

h=(5)/(8)* 20\Rightarrow 12.5\text{ foot}

Thus, Height of lamppost would be 12.5 feet.

Answer 2
Answer: 5 : 8 = x : 20
20*5 = 8x
x = 12,5
Therefore height of the lamp is 12.5 feet :)

0.75    ok!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!                                                               

la respuesta es de 0,75 , pero aquí es una explicación

Primero hay que poner más de 100. Así que lo que tiene que hacer para hacerlo es fijar encima de su problema como este : 3 = x 4 100 (como una fracción , no puedo obtener las líneas de ponerlo como una fracción) Luego hacen 3 veces 100 , que es igual a 300. Luego divida 300 por 4, que es 75. A continuación, poner 75 sobre 100. Puesto que ahora tiene el número 100 sobre lo que tiene que hacer equivalentt a 1,00 . Todo lo que tiene que hacer es mover el punto decimal del extremo dos lugares a la derecha . Por último , se mueve el punto decimal dos lugares a la derecha en el 75 por lo que es igual a 0,75 o 0,75 . Puesto que usted tiene el que acaba de escribirlo como 0,75 de 1,00.

Answer:

≈ $937

Step-by-step explanation:

to answer this, we have to use the compound interest formula which is:

A = P(1 + r/n)^nt

the meanings of each variable are:

A = result

P = principal amount

r = rate (in decimal form)

n = the number of compound periods (eg: annually, quarterly, etc)

t = time

in the word problem, we need to solve for A. we are given P, r, n, and t.

P = 800

r = 0.02 also known as 2%

n = 1 keyword being annually which is equal to the value of 1

t = 8

we can plug these values into the formula:

A = 800(1 + 0.02/1)^(^1^)^(^8^)

we can use a calculator to calculate this easier but ill break it down:

A = 800(1 + 0.02/1)^8

A = 800(1.02)^8

A = 800(1.02)^8

A = 800(1.17165938)

A ≈ 937.327

we can round 937.327 to the nearest dollar which is $937
