contains 8 × 104 bacteria, and Culture B
contains 4 × 106 bacteria. How do the two
cultures compare in size?
A. Culture A contains twice as many
bacteria as Culture B.
B. Culture A contains 1
2
as many bacteria as
Culture B.
C. Culture A contains 1
25
as many bacteria as
Culture B.
D. Culture A contains 1
50
as many bacteria as culture B.

Answers

Answer 1

Answer:

A.

Step-by-step explanation:

To get the answer, you will need to divide the number of bacterias that Culture A has by the number of bacterias that Culture B has.

Size=(8*104)/(4*104)

=2

So, A will be the correct answer. (I have corrected your answer's no. of bacterias that Culture B contains as 104.)

The line y=3x creates an acute angle theta when it crosses the x-axis, Find the exact value of sec theta

Answers

Answer:

Sec(θ) = 3

Step-by-step explanation:

First, we know that:

Sec(x) = 1/Cos(x)

Now we have an angle θ in the intersection between the line y = 3x and the x-axis.

Here we can think of this as a triangle rectangle, such that:

x is the adjacent cathetus to θ

y is the opposite cathetus to θ

y = 3*x is the hypotenuse.

Here we also need to remember the relation:

Cos(θ) = (adjacent cathetus)/(hypotenuse)

Then we will get:

Cos(θ) = x/(3*x) = 1/3

If we multiply both sides by 3, we get:

Cos(θ)*3 = (1/3)*3 = 1

Cos(θ)*3 = 1

Now we can divide both sides by Cos(θ)

[Cos(θ)*3]/Cos(θ) = 1/Cos(θ)

3 = 1/Cos(θ)

And  1/Cos(θ) = Sec(θ)

Then:

3 = Sec(θ)

The exact value of sec theta is 3.

First off we have to do all 6 faces remember that each face will have a matching face that goes along with it so Imma start with the front face that would be 9 x 5 = 45 same for back face

Then ill do sides that will be 5 x 4 = 20 for both left and right sides Then ill do top and bottom

thats 4 x 9 = 36 Now ill add all of these up.

So 45 + 45 + 20 + 20 + 36 + 36 and that = 202

if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total

Answers

Answer:

Approximately = 131 employees in total

Step-by-step explanation:

if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total?

Let us represent total number of employees = x

Hence,

42% of x = 55 employees

42/100 × x = 55

42x/100 = 55

Cross Multiply

42x = 100 × 54

x = 100 × 55/42

x = 130.95238095 employees

Therefore, there is approximately a total 131 employees

Explain how you found your answer.
Enter the correct answers in the boxes.

Answers

Answer:

150cm²

Step-by-step explanation:

In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?

The formula for the area of a trapezoid = 1/2(a + b) h

Where a = Length of the first base

b = Length of the second base

h= height of the trapezoid

h = 10cm

The length of one base is equal to its height

Hence:

a = h = 10cm

The length of the other base is twice its height.

b = 2h

h = 10cm

b = 10 × 2 = 20cm

Therefore, the Area of the Trapezoid =

1/2 (20 + 10)10

1/2 × 30 × 10

= 150cm²

A man has Rs 1900. he lent some of it at 5% p.a and rest at9% p.a. The total amount of interest which he got after4 years was Rs 580.Wwhat was the sum
ans= Rs650,Rs 1250​

Answers

Answer:

The sum is Rs 1,250 and Rs 650

Step-by-step explanation:

Let the amounts be represented as $x and $y

The sum of both is 1900

Thus;

x + y = 1,900 •••••(i)

Mathematically, the interest on the amount borrowed is;

I = PRT/100

where p is the principal, representing the amount borrowed

R is the rate

T is the time

for the first amount of $x ; we have interest as;

I = (x * 5 * 4)/100 = 20x/100

for the second, we have

I = (y * 9 * 4)/100 = 36y/100

The sum of both is 580

Thus;

20x/100 + 36y/100 = 580

20x + 36y = 58000 •••••(ii)

From equation i;

x = 1,900 - y

Substitute this into equation ii

We have this as;

20(1900-y) + 36y = 58,000

38000 - 20y + 36y = 58,000

16y = 58000 - 38000

16y = 20,000

y = 20,000/16

y = 1250

From equation 1;

x + y = 1900

x = 1900-y

x = 1900-1250

y = 650
