======================================================

Explanation

Those 4 semicircles can be joined to form 4/2 = 2 full circles.

Each circle has diameter 41 cm.

Let's find the circumference of one circle

C = circumference, d = diameter = 41, pi = 3.14

C = pi*d

C = 3.14*41

C = 128.74

That's the perimeter of one full circle. Double it to get

2*128.74 = 257.48 cm

Which is the total length of the wire.

The number of rate eaten by dog after 200 minutes: 2 pounds

A ratio is a divisional comparison of two quantities. It uses a fraction or quotient to represent the relationship between two numbers or quantities. For instance, we can describe the ratio 3:5 or the fraction 3/5 if we declare that there are 3 guys for every 5 ladies in a classroom.

Contrarily, the proportion equation declares that two ratios are equivalent. We can utilise proportion to solve problems with unknown amounts if we have two ratios that are equivalent.

We can use proportion to solve this problem:

If a dog eats 0.5 pound of food every 50 minutes, then in 1 minute, the dog will eat 0.5/50 = 0.01 pound of food.

Therefore, in 200 minutes, the dog will eat 0.01 x 200 = 2 pounds of food.

So the dog will have eaten 2 pounds of food after 200 minutes.

Answer:

5.25/25=0.21

Step-by-step explanation:

to find this you can do 0.21 times 25 which gets 5.25 so there is your answer

5.25/25=0.21 is the unit price per​ card.

Division is the process of splitting a number or an amount into equal parts.

Here, given that,

A store sells a package of 25 trading cards for​ $5.25.

So, price of per card = 5.25/25

                                  =0.21

(to find this you can do 0.21 times 25 which gets 5.25 )

Hence, 0.21 is the unit price per​ card.

Step-by-step explanation:

Answer:

Value of K:

K=6.5

Step-by-step explanation:

Parallel lines have the same slope.

m = (y2-y1)/(x2-x1)

m = (-3-3)/(4-0)

m = -6/4 = -3/2

Substitute the values in y = mx + c,

-5 = (-3/2)(6) + c

-5 = -9 + c

c = 4

y = (-3/2)x + 4

Thus, Option D is the correct answer
