Answer:

Resulting expression is - 0.8x + 4.8y +16.

Step-by-step explanation:

Given :  4(0.5x+2.5y-0.7x-1.3y+4).

To find  : what is the resulting expression.

Solution : We have given that  4(0.5x+2.5y-0.7x-1.3y+4).

First we will solve the parenthesis by combine like terms:

4( 0.5x - 0.7x +2.5y -1.3y +4).

4( - 0.2x + 1.2y +4).

Now distributes 4 over parenthesis's terms

- 0.8x + 4.8y +16

Therefore, Resulting expression is - 0.8x + 4.8y +16.

A person x inches tall has a pulse rate of y beats per​ minute, as given approximately by yequals600 x Superscript negative 1 di
tankabanditka [31]

Answer:

a) 5.13beats/min

b) 2.82 beats/min

Step-by-step explanation:

Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75

If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;

y = 600(39)^-1/3

y = {600(1/39)}/3

y = 600/39×3

y = 600/117

y ≈ 5.13beats/min

The instantaneous rate for a 39 inches tall person is 5.13 beats per min

b) For a 71inches tall person, the beat rate will be expressed as;

y = 600(71)^-1/3

y = {600(1/71)}/3

y = 600/71×3

y = 600/213

y ≈ 2.82 beats per minute

The instantaneous rate for a 71 inches tall person is 2.82 beats per min

The length of the rectangle is six times its width if the perimeter is 70cm find its area
Vesna [10]

Answer:

Step-by-step explanation:

Perimeter is 70 m

so w + w + 6w + 6w = 70

w = 70/14 = 5, l = 30m.

Area = l * w = 30 * 5 = 150 sq m
