How much does this fish weigh? How much does this fish weigh if it's tail weighs 4kg , it's head weighs as much as it's tail and half it's body, and it's body weighs as much as it's head and tail together?

Answers

Answer 1
Answer: Body Weight: w=(t+0.5w)+t
Tail Weight: t=4
Head Weight: t+0.5w

w=t+0.5w+t

But t=4,

w=4+0.5w+4

w-0.5w=8

0.5w=8

Therefore: w=16.

50 POINTS!! A 96-ounce container of juice costs $4.80. At what price should a 128-ounce container be sold in order for the unit rate for both items to be the same? Explain your reasoning.

Answers

Answer:

$6.40 because 32 ounces is the difference 128 and 96 hence 32 is 1/3 of 96 so divide $4.80 by 3 which is $1.60 then add $1.60 + $4.80 =$6.40

65% of students in a statistics class said that they liked statistics more than algebra. if 3 of these students are randomly selected, what is the probability that all 3 students said that they liked statistics more than algebra? express your answer as a decimal rounded to the thousandths place.

Answers

The answer to this question depends on the class size. However if we assume the class is sufficiently large then we can assume the 65% ratio stays relatively constant as students are selected. In this case we will treat selecting three students as independent events. Therefore we can multiply the probabilities. Finally, the probability of selecting three students that all like statistics more than algebra is (0.65)x(0.65)x(0.65) = 0.275.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

The area of a rectangular patio is (12x - 4) square units.

now,

We need two terms that multiply to (12x-4).

The term on the outside needs to be a common multiple of 12 and 4.

The common factors are 1, 2, and 4.

The length of a rectangle is 2 centimeters longer than its width. The perimeter is 16 centimeters. What are the length and width of the rectangle

Answers

The length of a rectangle is 2 centimeters longer than its width. The perimeter is 16 centimeters.

Length of rectangle = L

Width of the rectangle = W

The length of a rectangle is 2 centimeters longer than its width.

So L = W + 2

Perimeter of rectangle = 2* length + 2* width

Given perimeter = 16cm

Subtract 4 on both sides

12 = 4W

Divide by 4 on both sides

3 = W

So width of the rectangle = 3 cm

Length = W + 2 = 3+2 = 5 cm

6 centimeters long !!!!!!!

The volume of a cylinder is 980pi in3. The radius is 7 in. What is its height? A) 10 in
B) 140 in
C) 70 in
D) 20 in

Answers

Answer:

D) 20 in

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

Substituting what we know

980 pi = pi (7)^2 h

Divide each side by pi

980 pi /pi= pi 49 h/pi

980 = 49h

Divide each side by 49

980/49 = 49h/49

20 =h

Answer:

h ≈ 20 inches

Step-by-step explanation:

Given volume 980 pi inches cubed and radius 7 inches.

Using the height formula for right cylinder

h = V/π r^2

h = 3078.78/π7^2

h ≈ 20 inches
