There are (32)4 ⋅ 30 bacteria in a petri dish. What is the total number of bacteria in the dish?

Step-by-step explanation:

Given

[tex] = \frac{1.5 \times {10}^{4} \times 4.5 \times {10}^{3} }{2.5 \times 10 ^{2} } \\ = \frac{6.75 \times {10}^{4 + 3} }{2.5 \times {10}^{2} } \\ = \frac{6.75 \times {10}^{7} }{2.5 \times {10}^{2} } \\ = 2.7 \times {10}^{7 - 2} \\ = 2.7 \times {10}^{5} [/tex]

Hope it will help :)

Answer:

I think C

Step-by-step explanation:

Answer: The answer is D

Step-by-step explanation:

The wrong statement is, the area of the final square is equal to the area of the triangle with a hypotenuse of c, the correct option is D.

According to Pythagorean Theorem, for a right angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides.

The figure shows the first two steps of a proof of the Pythagorean theorem

In Pythagorean theorem, squares are used to prove the equality of the square of the bigger side with the sum of area of square of the other two smaller sides,

The area of the final square is not equal to the area of the triangle with a hypotenuse of c.

Answer:

The answer is below

Step-by-step explanation:

An independent variable is a variable that does not dependent on other variables. It is the input variable.

A dependent variable is a variable that is dependent on other variables. The dependent variable depends on the independent variable. It is the output variable.

Since porter receives 3 tickets for every dollar, this means the number of ticket is dependent on the money he spend. Therefore the money he spends (d) is the independent variable and the tickets (t) is the dependent variable.

Answer:

x = 0 satisfies the equation

Step-by-step explanation:

Here, we want to get the value of x that satisfies the equation

4(2.5)^2x = 4

divide both sides by 4

So, we have

2.5^2x = 1

2.5^2x = 2.5^0

Since bases area equal, we equate powers

2x = 0

x = 0/2

x = 0

Answer:

12.5

Step-by-step explanation:

40% is 0.4. 0.4 is 1/4. 1/4 * 50 is 12.5

Answer:

30 dollars.

Step-by-step explanation:

40% of 50 is 40/100 * 50 = 20

The price has been reduced by 20

The new price is 50 - 20 = 30 dollars

Answer:

BX

Step-by-step explanation:

D = RT is an extremely important and useful formula. This formula relates distance, to rate, and time.

In this question, we are asked to find the DISTANCE travelled in the biking portion of the triathlon. Looking back to the formula, we see that the distance is equal to the rate multiplied by the time.

The rate biking is also called the average speed, which is represented by an X in this problem.

The time biking is represented by a B in this problem.

Thus, we obtain our final answer, B times X, or simply written as BX.

B?

After comparing we get [tex]\mathbf{0.3\: <\: 0.7}[/tex]

Step-by-step explanation:

We need to compare the comparison below.

[tex]\frac{3}{10}\:?\:0.7[/tex]

For comparison both terms should be in decimal.

So, converting 3/10 into decimal we get 0.3

Now, [tex]0.3\:?\:0.7[/tex]

We know that 0.3 is less than 0.7

So, [tex]0.3\: \mathbf{<}\: 0.7[/tex]

So, after comparing we get [tex]\mathbf{0.3\: <\: 0.7}[/tex]

Answer:

y = 4x² - 44x + 120

Step-by-step explanation:

The formula to solve this will be;

y = c(x - a)(x - b)

Where;

c is the leading coefficient

a and b are the roots

Now, we are given that the roots are 6 and 5, while leading coefficient is 4.

Thus, equation is;

y = 4(x - 5)(x - 6)

Expanding gives;

y = 4(x² - 5x - 6x + 30)

y = 4(x² - 11x + 30)

y = 4x² - 44x + 120

Answer:

516

Step-by-step explanation:

Measure of quilt = 2160 in²

Covered by triangle = 432 in²

Covered by square =. 180 in²

Rest will be covered by parallelogram :

Base of parallelogram = 2 inches

Height of parallelogram = 1.5 inches

Number of parallelograms that should be cut:

Total area to be covered by parallelogram :

2160 - (432 + 180) = 1548 in²

Area (A) of each parallelogram :

A = b*h = 2 * 1.5 = 3 in²

Number of parallelograms

= Total area /area per parallogram

= 1548 in² / 3in²

= 516 parallelograms
