Step-by-step explanation:

I painfully counted every square to find that a 1 by 1 square is divided into an 8 by 8 square.

K is one square above 1/2, for the second coordinate is 4.

K is also 2 to the left of 0, so the first coordinate is 2.

Therefore, the coordinates of K are (2,4).

Isabella is bouncing a rubber ball that has a density of 1.5 ​ g/cm3 ​. The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?

Answers

Answer:

The mass of the rubber ball is 169.5g

Step-by-step explanation:

we know that

The density is equal to the ratio of the mass by the volume

D=m/V

Solve for m

m=D*V

In this problem we have

V=113 cm^3

D=1.5 g/cm^3

substitute

m.1.5*113=169.5g

So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula

a^2+b^2=c^2

now, we plug in what we have

12^2+x^2= 19^2
144+x^2= 361

Bring the variable to one side by subtracting 144 from each side

x^2= 217

Square root each side to get rid of the exponent on the x

x= 14.7309

Look at the right-angled triangle ABC.

32°

The square fits exactly inside the triangle.
Work out the sizes of angles x, y and z.

Answers

Answer:

∠x = 90°

∠y = 58°

∠z = 32°

Step-by-step explanation:

he dimensions of the angles given are;

∠B = 32°

Whereby ΔABC is a right-angled triangle, and the square fits at angle A, we have;

∠A = 90°

∠B + ∠C = 90° which gives

32° + ∠C = 90°

∠C = 58°

∠x + Interior angle of the square = 180° (Sum of angles on a straight line)

∠x + 90° = 180°

∠x = 90°

∠x + ∠y + 32° = 180° (Sum of angles in a triangle)

90° + ∠y + 32° = 180°

∠y = 180 - 90° - 32° = 58°

∠y + ∠z + Interior angle of the square = 180° (Sum of angles on a straight line)

58° + ∠z +90° = 180°

∴ ∠z = 32°

∠x = 90°

∠y = 58°

∠z = 32°

Step-by-step explanation:

A puppy’s weight increased from 12 pounds to 15 pounds. By what percentage did the puppy’s weight increase?

Answers

Answer:    25%

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

Work Shown:

A = old value = 12 pounds

B = new value = 15 pounds

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (15-12)/12 ] * 100%

C = (3/12)*100%

C = 0.25*100%

C = 25%

The positive C value indicates a percent increase

So effectively, we find the difference or change in weight (B-A) and divide it over the original weight (A). That leads to 0.25 which converts to 25%

Note that,

25% of 12 = 0.25*12 = 3

This says that the puppy gained 3 pounds, which is the value of B-A

Since the puppy gained 3 pounds, the new weight is 12+3 = 15 pounds

-----------

As an alternative, we could divide the two values B over A to find that

B/A = 15/12 = 1.25

Then subtract 1 from this result: 1.25 - 1 = 0.25 = 25%
