Do you guys know what is 6y-3(4/3y-2)

2 answers:

5 0

You'd solve it like this
6y-3 (4/3y-2)
6y-4y+6 (use the distributive property and multiply all the numbers inside the parentheses by -3)
2y+6 (add like terms)
That's pretty much it

6y - 3(4/3y - 2) = 0

Multiply everything in the parenthesis by -3.

6y - 12/3y + 6 = 0

Simplify.

6y - 4y + 6 = 0

Combine like terms.

2y + 6 = 0

Subtract 6 from both sides.

2y = -6

Divide 2 on both sides.

y = -3

Hope this helps!

Hello! I can help you with this! So, Mami Kudo ran 255.303 kilometers in 24 hours. I’m guessing that we have to find the answer in kilometers per hour. 255.303/24 is 10.6376 and other numbers or 10.64 when rounded to the nearest hundredth. Mami Kudo’s average speed was about 10.64 kilometers per hour.

Two days after a biology experiment there was 49 million bacteria present. Four days after the experiment there was 600.25 milli

nataly862011 [7]

Answer:

y=Ae^(1.25t)

Step-by-step explanation:

From the expression y=Ae^kt

After two days of the experiment, y = 49 million, t=2

After four days of the experiment, y= 600.25 million, t=4

A is the amount of bacteria present at time zero and t is the time after the experiment (in days)

At t=2 and y =49

49=Ae^2k…………….. (1)

At t=4 and y = 600.25

600.25=Ae^4k………… (2)

Divide equation (2) by equation (1)

600.25/49=(Ae^4k)/(Ae^2k )

12.25=e^2k

Take natural log of both sides

ln⁡(12.25) =2k

2.505⁡ =2k

k=1.25

The exponential equation that models this situation is y=Ae^(1.25t)

Circle A has a radius of 9.0 cm. The shortest distance between B and C on the circle is 8.5 cm. What is the approximate area of

love history [14]

Answer:

38.25 cm²

Step-by-step explanation:

We use the formula for the length of an arc to find the central angle of the sector of the circle.

Then we use the formula for the area of a sector of a circle to find the area.

Length of arc of circle of radius r:

$s = \dfrac{n}{360^\circ}2 \pi r$

s = arc length

n = measure of the central angle of the sector

$s = \dfrac{n}{360^\circ}2 \pi r$

$8.5~cm = \dfrac{n}{360^\circ}2 \pi \times 9.0~cm$

$n = 54.1^\circ$

Area of sector of circle of radius r:

$A = \dfrac{n}{360^\circ} \pi r^2$

A = area of sector of circle

n = measure of the central angle of the sector

$A = \dfrac{54.1^\circ}{360^\circ} \pi (9.0~cm)^2$

$A= 38.25~cm^2$
