Answer:

Population of bacteria at  time [tex]t = 6[/tex] is [tex]2441[/tex]

Step-by-step explanation:

The complete question is

If [tex]y = 10 (2.5)^t[/tex]represents the number of bacteria in a culture at time t, how many will there be at time [tex]t = 6[/tex]

Solution

Given

The population of bacteria after time t is equal to [tex]y = 10 (2.5)^t[/tex]

Population when at time [tex]t = 6[/tex]

We will substitute the value of time in above equation.

[tex]y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441[/tex]

Answer:

Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]51\ \text{minutes}[/tex]

Step-by-step explanation:

Laura's commute is [tex]x\ \text{minutes}[/tex]

Jackie's commute is

[tex]x+15[/tex]

Laura drives 12 minutes for every 17 minutes Jackie drives so

For every minutes Laura drives Jackie drives [tex]\dfrac{17}{12}\ \text{minutes}[/tex]

So,

[tex]\dfrac{17}{12}=\dfrac{x+15}{x}\\\Rightarrow 17x=12x+180\\\Rightarrow 5x=180\\\Rightarrow x=\dfrac{180}{5}\\\Rightarrow x=36\ \text{minutes}[/tex]

Hence, Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]36+15=51\ \text{minutes}[/tex].

Answer:

[tex]900\times 3^m[/tex] = 100

Step-by-step explanation:

The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]

Where m is the number of months after the number of visitors was measured.

We need to evaluate the above expression for m = -2.

So,

[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]

At m = -2, the value of the above expression is equal to 100.

Answer:

x = -2 and y= 2

Step-by-step explanation:

y=-2x-2 and -2x+4y=12

Substitute: -2x+4(-2x-2)=12

Distribute: -2x-8x-8=12

Combine like terms: -10x-8=12

Simplify: -10x=20

20/-10 = -2

Use that value to solve for y

y=-2x-2

Substitute x value: y=-2(-2)-2

Simplify: y=2

Answer:

A) 3 times more apple juice is used than carrot juice aka 22 more millimeters

B) 66 millimeters

Step-by-step explanation :

3 : 1 : 2     aka     33 : 11 : 22

You have the ratio, so you just have to divide 33/3 and you know you have to multiply that awnser times the other ratios.

So...

33/3 = 11

3 x 11 = 33

1 x 11 = 11

2 x 11 = 22

So the ratio is 33 : 11 : 22

Then, A is asking you how much more apple juice than carrot juice, so subtract ( amount of apple juice - amount of carrot juice )

33 - 11 = 22 millimeters more apple juice than carrot juice

Then, B is asking you how much juice is there in total. So just add all the juices together....

33+22+11 = 66

So 66 milimeters of juice all together

(a) The apple juice is 22 ml more than the carrot juice.

(b) The total amount of the mixture is 66 ml.

Important information:

(a)

Let the quantity of Apple, carrot, and celery is 3x, x, 2x respectively.

[tex]3x=33[/tex]

[tex]x=11[/tex]

Difference between Apple and carrot juice is:

[tex]3x-x=2x[/tex]

[tex]3x-x=2(11)[/tex]

[tex]3x-x=22[/tex]

Therefore, the apple juice is 22 ml more than the carrot juice.

(b)

The total amount of the mixture is:

[tex]3x+x+2x=6x[/tex]

[tex]3x+x+2x=6(11)[/tex]

[tex]3x+x+2x=66[/tex]

Therefore, the total amount of the mixture is 66 ml.

Answer:

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Step-by-step explanation:

Dinner = 1 box of pasta + 1jar of sauce

pasta is sold in package of 6 boxes

sauce is sold in in packages of 3

jars

what is the least number of dinners that manny can make without any supplies leftover?

Find the lowest common multiple of 6 boxes and 3 jars

6 boxes = 6, 12, 18, 24, 30, 36, 42,48

3 jars = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

The lowest common multiple of 6 boxes and 3 jars = 6

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Using:

Pasta = 6 dinners / 6 boxes

= 1 package

Pasta = 1 package

Sauce = 6 dinners / 3 jars

= 2 package

Sauce = 2 package

Answer:

-364

Step-by-step explanation:

ok so just followed the equation and got that

Answer:

y= -1, x= -1

5x+6y=-11

-(5x-2y=-3)

     8y=-8

      y=-8/8

      y= -1

5x+6(-1)=-11

5x-6     = -11

        5x=-11+6

        5x=-5

          x=-5/5

          x=-1

The required solution of the simultaneous equation is x = -1 and y = -1.

Given that,
To solve the given simultaneous equation,
5x+6y= −11
5x = 2y −3

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

here,
5x = 2y −3 - - - - - (1)
5x+6y= −11
By substitution, from equation 1
2y - 3 + 6y = -11
8y = -8
y = -1
Now,
5x = -2 - 3
x = -1

Thus, The required solution of the simultaneous equation is x = -1 and y = -1.
