In a lab experiment, 30 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 6 hours. How many bacteria would
there be after 19 hours, to the nearest whole number?

Answers

After 19 hours the number of bacteria will be 193.8.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:

The number of bacteria will be calculated as,

30 x ((2/6) x 19) = X

30 x (0.34x 19) = X

30 x 6.46= X

193.8= X

April May and June have 90 sweets between them. May has three-quarters of the number of sweets that
June has.
April has two-thirds of the number of sweets that may has. How many sweets does June have?

I NEED AN ANSWER ASAP! PLEASE ​

Answers

Answer:

40

Step-by-step explanation:

The number of sweets in June is  40

Let the number of sweets June have is "Q"

Given that April,  May  and  June collectively have 90 sweets.

Also,  May has three-quarters of the number of sweets that as that of  

June

[tex]\rm Number \; of \; sweets\; for \; May = \dfrac{3Q}{4}[/tex]

Also it is given that April has two third of the sweets that May has hence we can write

[tex]\rm Number \; of \; the \; sweets\; in \; the\; April = \dfrac{2}{3}\times \dfrac{3}{4}Q = Q/2[/tex]

According to the given condition the total number of sweets in three months  is 90 sweets  which can be  solved further in the following way

[tex]\rm \dfrac{Q}{2} + \dfrac{3}{4} Q+ Q = 90 \\\\Q( 0.5 + 1.5 +0.75) = 90\\\\Q = 90/2.25 = \bold{40}[/tex]

So the number of sweets in June is 40

Mr. Jones has 550 goats, which is 10% more than Mr. King has. How many more goats does Mr. Jones have than Mr. King?

Answers

Answer:

55

Step-by-step explanation:

Number of Jone's goats = 550

Let Number of King's goat = x

Jone's goat is 10% more than King's ;

Thus, number King's goat would be ;

x = 550 - (10% of 550)

x = 550 - 55

x = 495

x = Mr. King's goat

Hence, Jones goat is :

550 - 495 = 55 more than Mr King's goat.

Mr King has 55 goats

Number of goats owned by Mr Jones is 550

let y represent the goats owned by Mr King

y= 550-(10% × 550)

= 550- (0.1×550)

= 550 - 55

= 495

= 550-495

= 55

Hence Mr King has 55 goats than Mr Jones
