A single bacterium lands in your mouth and starts growing by a factor of 4 every hour. After how many hours will the number of bacteria exceed 1,000?

Answers

Answer:

After 5 hours, the number of bacteria will be 1024

Step-by-step explanation:

1 times 4 = 4

4 times 4 = 16

16 times 4 = 64

64 times 4 = 256

256 times 4 = 1024

It will take around 5 hours to exceed 1000

Three vertices of parallelogram WZXY are W(-5, 2), X(2, 4) and Z(-7, -3). Find the coordinated of the vertex, Y.

Answers

Answer:

[tex]Y = (4,9)[/tex]

Step-by-step explanation:

Given

[tex]W(x_1,y_1) = (-5, 2)[/tex]

[tex]Z(x_4,y_4) = (-7, -3)[/tex]

[tex]X(x_2,y_2) = (2, 4)[/tex]

Required

Find Y

To do this, we make use of the mid-point formula

i.e.

[tex]M = \frac{1}{2}(x_n+x_m,y_n+y_m})[/tex]

WX and ZY are the diagonals of the parallelogram.

The mid-point of WX is:

[tex]M = \frac{1}{2}(-5+2,2+4)[/tex]

[tex]M = \frac{1}{2}(-3,6)[/tex]

The mid-point of ZY is:

[tex]M = \frac{1}{2}(-7+x,-3+y)[/tex]

Equate both values of M

[tex]\frac{1}{2}(-3,6) = \frac{1}{2}(-7+x,-3+y)[/tex]

Multiply both sides by 2

[tex](-3,6) = (-7+x,-3+y)[/tex]

By comparison:

[tex]-7 + x = -3[/tex]

[tex]-3 + y = 6[/tex]

[tex]-7 + x = -3[/tex]

[tex]x = 7 -3[/tex]

[tex]x = 4[/tex]

[tex]-3 + y = 6[/tex]

[tex]y = 6 +3[/tex]

[tex]y = 9[/tex]

Hence:

[tex]Y = (4,9)[/tex]

A banana costs three times as much as an apple. The total cost of 1 banana and 1
apple is $1.60. If a represents the cost of 1 apple, which equation could you use to
find a?

Answers

Answer:

banana cost 1.20 and the apple cost 0.4

Step-by-step explanation:

1.60 divided by 4 = 0.4 and the cost of apples

1.60 - 0.4 = 1.2 and the cost of bananas

since the banana cost three times you divide by two and subtract that number from the total cost to get three times the amount of the apples price. hope this helped sorry for my spelling

What is 11/2 subtracted by 11/3​

Answers

Answer:

11/6

Step-by-step explanation:

Answer:

1 5/6

First make it a mixed number. 11/2=5 1/2. 11/3=3 2/3. Next, you find the common denominator. 2 and 3 are both multiples of 6. You multiply 11x3=33, 2x3=6, 11x2=22 3x2= 6. Your new numbers are 5 3/6 and 3 4/6. Now you subtract. 5-3=2, but you have to regroup, so you end up with 1. 9/6-4/6=5/6. 1+5/6=1 5/6

How do you solve this equation

2x+5y=-2

-2x-7y=6

Answers

Answer: x=4, y=-2

For this system of equations, we can use the elimination method, where two variables from both equations will cancel our (in this case, 2x and -2x.

Adding the equations gives us -2y=4, where solving for y gives us -2.

Plugging -2 into any of the two equations and solving for x will result in x=4.

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number

Answers

Answer:

8

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.
