Mathematics

To do this equation, you need to convert 4 hours into seconds, which is 14400 seconds. Or you can convert the 8 seconds to hours, which is 0.08 hours. Then, you have a fraction (8/14400) which you can convert into a decimal by dividing it. The answer to this is 0.0006. From here you can convert it to a percentage, which is 0.0006%

A culture started with 2,000 bacteria. After 8 hours, it grew to 2,400 bacteria. Predict how many bacteria will be present after
Debora [2.8K]

Answer:

2950 [Starting from 2,000 bacteria.]

Step-by-step explanation:

400/8 = 50

Bacteria grown/time = bacteria per hour

19x50 = 950

time x bacteria per hour = bacteria grown

2000 + 950

bacteria started + bacteria grown

Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.
Alik [6]

Given:

In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.

To find:

The value of x.

Solution:

Pythagoras theorem: In a right angle triangle,

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

Using Pythagoras theorem, we get

(x)^2=(5)^2+(5.6)^2

x^2=25+31.36

x^2=56.36

Taking square root on both sides, we get

x=\sqrt{56.36}

x=7.50733

x\approx 7.5

The measure of missing side is 7.5 ft. Therefore, the correct option is D.

Who is correct Finn or Fiona
suter [353]
Fiona is correct- if a shape dilated by a fraction it’s always smaller, unless in the fraction the bigger number is on top. So if it’s more than 1 the shape gets bigger. And if it’s less than one it always gets smaller. Hope this didn’t confuse you even more.

All triangles are similar.
.. x/3 = 27/x
.. x^2 = 81
.. x = 9

.. y = √(x^2 -3^2) = √72
.. y = 6√2

Which description is represented by a discrete graph?
ozzi

Answer:A)

Kiley bought a platter for $19 and several matching bowls that were $8 each. What is the total cost before tax

here x will be number of bowl which can only be dicrete value e.g 1 , 2 , 3 , 4 ...

Step-by-step explanation:

A discrete graph is a series of scatter plot points. It means point on graph aren't continuous manner.

A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, only integers or whole numbers.

Example

Number of student, x

x can only be integer
