Answer:

5.52%

Step-by-step explanation:

there is a 5.52% chance of it not improving you do 69% of 8 and that determines if its not gonna get better.

Answer:

(2,4)

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).

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

(7 + 8 + 10 + 10 + 12 + 15) / 6 = 10.333

Answer:

rectangle = 2(50) +2(70) + 2(35) = 310

square = 2(32) + 2(12) + 2(24) = 136

Add

136 + 310 = 446 cm^2

SA = 446 cm^2

Answer:

  C ≈ 0.00106455765168

Step-by-step explanation:

This is the sum of 13 terms of the geometric series that has 10000C/1.05 as the first term and a common ratio of 1/1.05. The sum S is given by ...

  S = a1(1 -r^n)/(1 -r) . . . . a1 is the first term, r is the common ratio

Using the known values, we have ...

  100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))

  0.01 = C(1 -1.05^-13)/0.05

  C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679

  C ≈ 0.00106455765168

Answer:

C ≈ 0.00106455765168

Step-by-step explanation:

100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))

 0.01 = C(1 -1.05^-13)/0.05

 C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679

 C ≈ 0.00106455765168

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

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%

Answer:

the correct answer is3 1/2

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°
