Answer:

the number of viruses are in Dish A is 3,391 viruses

Step-by-step explanation:

The computation of the number of viruses are in Dish A is shown below:

Since there are 2826 square milimeters area

And, the population density of 1.2 viruses per square

So, the number of viruses in Dish A is

= 2826 × 1.2

= 3,391.2v viruses

Hence, the number of viruses are in Dish A is 3,391 viruses

The answer is B. 3,391 viruses

Good luck :)

Answer:

y=2x+7

Step-by-step explanation:

y=mx+b is the formula

y=(2) × x+b

y= (2)×(3)+b

y=(2)×(3)+b

b=7

Equation: y=2x+7

Answer:

Jim drove the truck 156 miles

Step-by-step explanation:

Represent the number of miles driven with x.

Then the formula for the total rental cost is C(x) = $17.95 + ($0.87/mile)x, and this comes to $153.67.  Solve for x:

$153.67 - $17.95 = ($0.87/mile)x, or

$135.72 = ($0.87/mile)x

Dividing both sides by ($0.87/mile), we get:

x = 156

Answer:

Each girl (m) had $18.

Step-by-step explanation:

The Equation to determine the amount of money, m, each girl received is 4m = 72 or m = 12(4) + 24

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Each girl spent $12.

Afterward, the girls had $24 altogether.

let each Girl received amount of $x.

So, the four spend = 12 x 4 = $48

Then, the total they have = 48 + 24 = $72

So, each of Girl have = 72/ 4 = $18.

h=4

Height of trapezoid is,

⇒ h = 4 km

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The area of the trapezoid is 24 Square km.

We know that;

Area of Trapezoid = (a + b) h / 2

Here, A = 24 km² , a = 3 km , b = 9 km

Hence, We get;

24 = (3 + 9) h / 2

48 = 12h

h = 48 / 12

h = 4 km

Thus, Height of trapezoid is,

⇒ h = 4 km

Answer: $6,500

Step-by-step explanation:

Question says after 10 years.

The value of the car depreciates by 1/2 every year which is 50%, every 5 years.

In 10 years therefore, the car would have depreciated by half of its value, twice.

Use the future value formula:

= Amount * (1 + rate) ^ no. of periods

= 26,000 * ( 1 - 50%)²

= $6,500

Note: There are two periods because the depreciation is every 5 years and 10 years have gone by so the number of periods is: 10 / 5 = 2 periods

Step-by-step explanation:

The equation for triangle 2 will be: a² + b² = n².

What is Pythagorean theorem?

Pythagorean theorem states that for a right-angle triangle, the sum of the squares of the base and the height is equal to the square of the hypotenuse of that triangle.

Here, the angle between side: a and side: b is a right-angle.

Therefore, we can consider side: a as the height and side: b as the base of the triangle.

Therefore we can write as per the Pythagorean theorem:

(Base)² + (Height)² = (Hypotenuse)²

Hence, a² + b² = n²
