Solve for k. 6k - 8 = 4K + 15

Answer:

k=23/2=11.5

Step-by-step explanation:

So we have the equation:

6k-8=4k+15

Add 8 to both sides. The left side cancels:

6k=4k+23

Subtract 4k from both sides. The right side cancels:

2k=23

Divide both sides by 2:

k=23/2=11.5

And we're done!

Hi,

Answer:

k = \frac{23}{2}

Step-by-step explanation:

Subtract 4k from both sides

6k - 4k = 2k

2k - 8 = 15

Add 8 on both sides (you want to get rid of the 8 in order to leave the k alone)

2k = 23

k = 23/2

Have a good day!

Find the number of bacteria after 10 minutes?​
aleksandr82 [10.1K]

Answer:

Number of bacteria when t = 10 min is 3,000

Step-by-step explanation:

Given:

Number of bacteria in a culture by equation

Q(t) = 2(729^t)

Value of t = 10 min = 10 / 60 = 0.1667 hour

where t is number of hours

Find:

Number of bacteria when t = 0.1667 hour

Computation:

Given equation

Q(t) = 2(729^t)

Put t = 0.1667

Q(10) = 2(729⁰'¹⁶⁶⁷)

We know that;

a⁰ = 1

So,

Q(0.1667) = 2(729⁰)

Q(0.1667) = 3

Number of bacteria when t = 0 is 3,000

Line segment EF begins at (-1,5) and ends at (-1, -3). The segment is translated to the right 4 units and down
nignag [31]

The coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

Line segment EF begins at (-1, 5) and ends at (-1, -3). The segment is translated right 4 units and down 2 units to form line segment E'F'. Then the coordinate of E' and F' will be:

E' = (-1 + 4, 5 – 2) = (3, 3)

F' = (-1 + 4, -3 - 2) = (3, -5)

\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of the E'F' = √(0 + 64) = 8 units

Thus, the coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.

Answer:

556

Step-by-step explanation:

Find out how much 1.4% is of 500 which is 7

so 7 x 8 = 56

now we add it 500 + 56 = 56
