Mathematics
1 answer:
Nostrana [21]3 years ago

c = 4/5(kp + m)
Divide both sides by 4/5 or multiply by 5/4
5/4c = kp + m
Subtract m from both sides
5/4c - m = kp
Divide by k on both sides
(5/4c - m) / k = p


p = (5/4c - m) / k

Translate this phrase into an algebraic expression.
Levart [38]

Answer:

(n*19)-4

Step-by-step explanation:

A product is the result of multiplication, so the product of a number (represented as n) and 19 would be n*19. Put these in parentheses, so that it remains organized and you don't become confused later.

Then 4 less would simply mean you subtract 4 from the product of n and 19.

(n*19)-4

B/4 + 2 = -1<br><br><br><br> Please help, I’ll give brainliest to whoever answers correct first.
leva [86]

Answer:

\frac{b}{4}+2=-1

Subtract 2 from both sides:

\frac{b}{4}+2-2=-1-2

\frac{b}{4}=-3

Multiply 4 to both sides:

4*\frac{b}{4} =-3*4

b=-12

Una botella pesa 1090kg cuando esta llena y 250g cuando esta vacía. ¿Cuanta masa de aceite contiene la botella?
Hitman42 [59]

Respuesta:

1089,75 kg

Explicación paso a paso:

Dado que :

Masa de embotellado lleno = 1090 kg

Masa de la botella vacía = 250 g

Masa de aceite que contiene la botella:

Expresando la masa de la botella cuando se llena en gramos:

1000 g = 1 kg

1090 kg = (1090 * 1000) = 1090000 g

La masa de aceite que contiene la botella es así:

Masa de la botella cuando está llena - masa de la botella cuando está vacía

1090000 g - 250 g = 1089750 g

Por tanto, la masa de aceite es 1089750 g

O 1089750/1000 = 1089,75 kg

In mostar, bosnia, the ultimate test of a young man's courage once was to jump off a 400-year-old bridge (now destroyed) into th
Alex787 [66]

To solve this problem, we must assume that the man undergoes constant acceleration as he goes down the river (therefore no other forces must act on him except gravity). Therefore we can use the formula below to calculate for the duration of his fall:

y = y0 + v0 t + 0.5 a t^2

where y is the distance and y0 = 0 since we set the reference point at the bridge, v0 is the initial velocity and is also equal to v0 = 0 since the man started from rest, therefore the equation becomes:

y = 0 + 0 t + 0.5 a t^2

y = 0.5 a t^2

Rewriting in terms of t:

t^2 = 2 y / a

t = sqrt (2y / a)

a is acceleration due to gravity = 9.8 m/s^2

t = sqrt [2 * 23 / 9.8]

t = 2.17 s

 

Therefore the jump last only about 2.17 seconds.
