Answer:

Shaded region is the difference of the areas of the parallelogram and the square:

Answer:

area of shaded region=1125m²

Solution given:

base of parallelogram [b]=45m

height of parallelogram [h]=30m

length of square [l]=15m

we have

Area of shaded region =Area of {parallelogram -square]

=b×h-l²=45×30-15²=1125m²

The photo isn't clear but

1st one is increasing slope

2nd is decreasing slop

3rd one also increasing

4th one is undefined slope Cuz its vertical slope

5th one sry I don't know

6th one is 0 Cuz it's horizontal line

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: a^+b^2=n^2

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

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

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:

9+3=12

12x1/2=24

24/6=4

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:

Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.

Step-by-step explain

The given inequality is 3b + 8 ≥ 14

We need to solve the given inequality

Step 1.

Subtract 8 to the both sides of the inequality

3b + 8 - 8 ≥ 14 -8

3b ≥ 6

Dividing both sides by 3

b ≥ 2

The value of b is greater than and equal to 2.
