irakobra [83]

The player has a total of 18 goals scored and 6 assists made.

<h3>Equation</h3>

Equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of goals scored and y represent the number of assists. Since the combined goals and assist is 24, hence:

x + y = 24     (1)

Also:

2x + y = 42    (2)

From equation 1 and 2:

x = 18, y = 6

The player has a total of 18 goals scored and 6 assists made.

a 29 gram sample of a substance that's used to preserve fruits and vegetables has a k-value of 0.1359. Find the substance's half
kaheart [24]
Okay well
a(t)= amount of substance remaining after t days
assuming exponential decay, a(t)=29e^-0.1359t

now, find the half, set a(t)= half the original and solve for t

14.5=29e^-0.1359t
0.5=e^-0.1359t
In(0.5)=In(e^-0.1359t)
In(0.5)=-o.1359t

t=in(0.5)/(-0.1359)= (aprox) 5.1 days

Can someone please help me answer this question.?

Answer:

d=8.0 meters

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

We are given the volume and the height

117.23 and the height 7

117.23 = 1/3 *3.14 *r^2 * 7

117.23 = 7.3266666666 *r^2

Divide each side by 7.3266666666

117.23/7.3266666666 = 7.3266666666 *r^2/7.3266666666

16.00045496 = r^2

Take the square root of each side

sqrt(16.00045496) =sqrt( r^2)

4.000 = r

We found the radius but it wants the diameter

d = 2*r

d =2*4.0

d=8.0 meters
