A colony of bacteria starts out with 175 cells and they double every hour write an equation that models the number of cells y after x hours

Answer:

x = -6 & y= 42

Step-by-step explanation:

I hope this helps :)

x = 6, y = -42

Substitution:

-7x = -5x - 12

-2x = -12

x = 6

When x = 6,

y = -7(6) = -42

Answer:

the awnser is. (-5) + (-12)

Answer: 7, -5+12

Step-by-step explanation:

Minus a negative is just like adding so -5 -( -12) would be the same as -5+12 which is 7

Answer:

1009

Step-by-step explanation:

0,25 x 2018 = 504,5

20,18 x 25 = 504,5

504,5 + 504,5 = 1009

Answer:

1,009

Step-by-step explanation:

[tex] \frac{25}{100} \times 2018 = 504.5[/tex]

[tex] \frac{2018}{100} \times 25 = 504.5[/tex]

[tex]504.5 + 504.5 = 1009[/tex]

180 students in the enviormental club

There are 60 students in the Environmental club.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

There are 240 students in the seventh grade,

and 25% are in the Environmental Club.

That means,

students are in the Environmental Club,

= 240 x 25/100

= 60

Therefore, 60 students are in Environmental club.

Step-by-step explanation:

Answer:

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Step-by-step explanation:

Formula for the simple interest is,

Interest = [tex]\frac{P\times r\times t}{100}[/tex]

Here, P = Principal amount

r = rate of interest  

t = Duration of investment

Let Phyllis invested amount (at 5.25% rate of interest) = $x

Therefore, Interest on this amount,

Interest = [tex]\frac{5.25\times x}{100}[/tex]

             = $0.0525x

If he invested the rest amount $(13000 - x) at the rate of 5%,

Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]

                                                    = $(650 - 0.05x)

Interest earned on total amount = $672

Therefore, $0.0525x + $(650 - 0.05x) = $672.5

0.0025x + 650 = 672.5

0.0025x = 22.5

x = $9000

Rest amount = 13000 - 9000

                     = $4000

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Step-by-step explanation:

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24
