Last month, when Joe took his puppy to the veterinarian, the puppy weighed 4.8 pounds. This month, the puppy weighed 7.2 pounds. What is the percentage increase of the weight of the puppy?

Step-by-step explanation:

Given

Radius (r) = 3 inch

Circumference

= 2πr

= 2 * 3.14 * 3

= 18.84 inch

Now

Area

= π r²

= 3.14 * 3 ²

= 3.14 * 9

= 28.26 inch²

Hope it will help :)

Answer:

1728

Step-by-step explanation:

Volume=length*width*height

Vol=18*8*12=1728 cubic inches

Answer:

let length be l and breadth 1/4×l

perimeter of the rectangle =600ft

2(l+1/4×l)=600ft

(4l+l)/4=600/2

5l=300×4

l=1200/5=240ft

Step-by-step explanation:

240ft is the length of a rectangular.

Answer/Step-by-step explanation:

A1. Reference angle = 41°

Hypotenuse = x

Adjacent = 7

Thus, applying trigonometric ratio, we would have:

Cos 41 = 7/x

Multiply both sides by x

x × cos 41 = 7

Divide both sides by cos 41

x = 7/cos 41

x = 9.3 (nearest tenth)

A2. Reference angle = 65°

Hypotenuse = 6

Opposite = y

Thus, applying trigonometric ratio, we would have:

Sin 65 = y/6

Multiply both sides by 6

6 × sin 65 = y

5.4 = y (nearest tenth)

y = 5.4

A3. Reference angle = 50°

Hypotenuse = z

Opposite = 8

Thus, applying trigonometric ratio, we would have:

Sin 50 = 8/z

Multiply both sides by z

z × sin 50 = 8

Divide both sides by sin 50

z = 8/sin 50

z = 10.4 (nearest tenth)

B1. Reference angle = 49°

Hypotenuse = x

Opposite = 7

Thus, applying trigonometric ratio, we would have:

Sin 49 = 7/x

Multiply both sides by x

x × sin 49 = 7

Divide both sides by sin 49

x = 7/sin 49

x = 9.3 (nearest tenth)

B2. Reference angle = 25°

Hypotenuse = 6

Adjacent = y

Thus, applying trigonometric ratio, we would have:

Cos 25 = y/6

Multiply both sides by 6

6 × cos 25 = y

y = 5.4 (nearest tenth)

B3. Reference angle = 40°

Hypotenuse = z

Adjacent = 8

Thus, applying trigonometric ratio, we would have:

Cos 40 = 8/z

Multiply both sides by z

z × cos 40 = 8

Divide both sides by cos 40

z = 8/cos 40

z = 10.4 (nearest tenth)

Answer:

$30

Step-by-step explanation:

Answer:

$15 dollars

Step-by-step explanation:

We know that Jen sells flowers. We also know that she charges $2 dollar per flower plus a $3 dollar delivery fee.

The question is asking how much will Jen make if she sells 6 flowers. Since every flower costs 2 dollars, we can multiply the cost and amount.

6 * 2

12.

Jen makes 12 dollars just by the flower, and now the delivery fee which is an extra 3 dollars.

12 + 3

$15

Answer:

Cube 1 = 30 cubic

Cube 2 = 48 cubic

Cube 3 = 72 cubic

Step-by-step explanation:

Cube 1 = 5x2x3

Cube 2 = 6x2x4

Cube 3 = 8x3x3

Step-by-step explanation:

Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).

For x + 6 if x < 2,

It becomes 2(x + 6) if x < 2.

We have 2x + 12 if x < 2.

For x² + 4x - 15 if 2 <= x <= 5,

It becomes 2(x² + 4x - 15) if 2 <= x <= 5.

We have 2x² + 8x - 30 if 2 <= x <= 5.

For 5 - x if 5 < x,

It becomes 2(5 - x) if 5 < x.

We have 10 - 2x is 5 < x.

The answer is the 1st option.

Answer:

y = 2x + 2

Step-by-step explanation:

add two to both sides so that (-)2 cancels out on the side by the y to get it by itself move +2 to the side with the x giving you y = 2x + 2

The adult weight of the puppy of Andre puppy be 30 pounds.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Andre has a puppy that weighs 9 pounds.

The vet says the puppy is now at 30% of its adult weight.

Let n pounds be the weight of an adult.

Using the percentage formula,

9 = 30 x n /100

n = 900/30

n = 30 pounds

Therefore, adult puppy weight is 30 pounds.

Answer:

Because they both equal d, you can set them equal to each other:

[tex]941-12t=523+26t\\418 = 38t\\t = 11[/tex]

Substitute t = 11 into the equation 523 + 26t = d:

[tex]523 + 26 *11 = d\\523 + 286 = d\\809 = d[/tex]

Answer:

K = 12, so the correct answer is D.

Step-by-step explanation:

- [tex]\frac{5}{6}[/tex]K = -10

-5K = -60 (Multiply 6 to both sides)

K = 12 (Divide both sides by 5)

so normally we would be finding the area of a triangle which is a=h*b/2

but in this case we are finding the height so theirs 3 ways to do this but i prefer the basic way

20=1/2(5)h

20=2.5

8=h

and to find out if that was correct lets do  8*5=40      40/ 2 =20  so this is correct

the height is 8

Answer:8

Step-by-step explanation:

Answer:

a = -8

Step-by-step explanation:

you can solve this proportion by cross-multiplying:

4(a + 9) = -1(a + 4)

now distribute to eliminate parentheses

4a + 36 = -1a - 4

5a + 36 = -4

5a = -40

a = -8
