John ran 3 miles in 25.2 minutes. The equation y = 8.5x, where x represents the number of miles and y represents the total time in minutes, represents this situation. What is the constant of proportionality? What does the constant of proportionality represent in the context of the problem?

Answers

Answer 1

Step-by-step explanation:

It is given that,

John ran 3 miles in 25.2 minutes. We can find the speed of john as follows :

Speed = distance/time

v = [tex]\dfrac{3\ \text{miles}}{25.2\ \text{minutes}}=0.1190\ \text{miles/minutes}[/tex]

The equation y = 8.5x, where x represents the number of miles and y represents the total time in minutes, represents this situation. y is proportional to x with constant of proportionality 8.5.

Velocity of John is 0.1190 miles/minute. We can write it in the form of equation as :

y = 0.1190x

In this problem, the constant of proportionality is 0.1190.

Suppose that a family wants to increase the size of the garden which is currently 16 feet long and 8 feet wide without changing the basic shape of the garden. That is, the family wants to ensure that the length of the garden remains twice the width (see figure).

1. Write an equation for the area of the new garden.
2. Write an equation that calculates how much more area the new garden will have as compared to the current garden. Simplify the equation into a quadratic equation in standard form.
3. Using the equation from Exercise 2, determine what effect increasing the width of the garden by two feet will have on the length of the garden and the total area of the garden.
4. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be 160 square feet larger than its original area.
5. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be four times its original area.

Answers

Answer:

See below

Step-by-step explanation:

Sides of the garden

16 feet and 8 feet

New dimensions of the garden

16 + 2x and 8 + x

1. The area of the new garden

(16 + 2x)(8 + x) = 2x^2 + 32x + 128

2. The difference in area

2x^2 + 32x + 128 - 16*8 = 2x^2 + 32x

3. x= 2 effect on the area

2*2^2 + 32*2 = 8 + 64 =72 ft²

4. Area difference = 160

2x^2 + 32x = 160x^2 + 16x - 80 = 0Solving we get positive root of 4 ft

5. Area difference = 4 times

2x^2 + 32x = 128*32x^2 + 32x - 384 = 0x^2 + 16x - 192= 0Solving we get positive root of 8 ft

Find the value of c so that (x+1) is a factor of the polymonial p(x)=5x^4+7x^3-2x^2-3x+c

Answers

Answer:

BRAINLIEST PLZZZZ

Step-by-step explanation:

Also given that (x+1) is factor of given polynomial p(x).

Need to determine value of constant c.

We will be solving above problem using factor theorem.

Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.

As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .

According to factor theorem p(-1) = 0

On substituting x = -1 , in given expression of p(x) we get

Hence value of c in the given polynomial is 1

Answer:

c = - 3

Step-by-step explanation:

[tex] \because [/tex] (x+1) is a factor of the polymonial [tex] p(x)=5x^4+7x^3-2x^2-3x+c[/tex]

Let (x + 1) =0[tex] \implies [/tex] x = - 1

[tex] \therefore [/tex] at x = - 1, p(x) =0.

[tex]p(x)=5x^4+7x^3-2x^2-3x+c \\ \\ 0 = 5( { - 1})^{4} + 7( { - 1})^{3} - 2( { - 1})^{2} - 3( - 1) + c \\ \\ 0 = 5 \times 1 + 7( - 1) - 2 \times 1 + 3 + c \\ \\ 0 = 5 - 7 - 2 + 3 + c \\ \\ 0 = 7 - 7 + 3 + c \\ \\ 0 = 3 + c \\ \\ c = - 3[/tex]

Answer:

The two bowling alleys cost the same when there are 10 people in the group.

Step-by-step explanation:

Bustlin' Bowling first:

$35 base price and then $2 for each person. You can model that with b = 35 + 2x where b is the price and x is the guest number.

Grand Entertainment next:

$20 base price and then $3.50 for each person. You can model that with g = 20 + 3.5x where g is the price and x is the guest number.

So the question asks for the number of people (or what's x) that makes the cost of both bowling places equal.

In variables, it's asking when b = g, what is x?

Starting with b = g, we can replace those with the actual equations. If b = 35 + 2x and g = 20 + 3.5x, then b = g is the same as 35 + 2x = 20 + 3.5x.

I think you know how to solve that (because the trickiest part is usually translating the words into a solvable equation) but in case you don't, here's how:

35 + 2x = 20 + 3.5x

Subtract 2x from both sides.

35 = 20 + 3.5x - 2x

35 = 20 + 1.5x

Subtract 20 from both sides.

35 - 20 = 1.5x

15 = 1.5x

Divide both sides by 1.5.

15/1.5 = 1.5x/1.5

10 = x

Sooo, the answer is 10 people.

Use the distributive property to multiply −2 by −4n+1.

8n−2+5(25n−8)=−62

Use the distributive property to multiply 5 by 25n−8.

8n−2+125n−40=−62

Combine 8n and 125n to get 133n.

133n−2−40=−62

Subtract 40 from −2 to get −42.

133n−42=−62

Add 42 to both sides.

133n=−62+42

Add −62 and 42 to get −20.

133n=−20

Divide both sides by 133.

n=-20/133

Fraction −20/133≈−0.15037594 can be rewritten as −20/133 ≈−0.15037594 by extracting the negative sign.

Twice Use what you have learned to compare circles by their characteristics. 1. Draw each circle. A. Radius length of 3 centimeters b. Diameter length of 3 centimeters 2. Describe the similarities and differences between your two circles. 3. Describe the relationship between the circumferences of the two circles. 4. Describe the circumference-to-diameter ratio of all circles.

Answers

Answer:

1. a. Please find attached, the diagram for the first circle with radius = 3 cm

b. Please find attached, the diagram for the second circle with diameter = 3 cm

2. The similarities are;

a) Both circles can be described by a point and a radius or a diameter

The differences are;

a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)

b) The circumferences of the two circles are different

c) The area covered by the two circles are different

3. The circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm

4. The circumference to diameter ratio of the circle with radius  = 3 cm is π

The circumference to diameter ratio of the circle with diameter  = 3 cm is π

Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter

Step-by-step explanation:

1. a. The radius length of the first circle = 3 cm

The diagram for the first circle with radius 3 cm is attached

b. The diameter length of the second circle = 3 cm

The diagram for the second circle with diameter 3 cm is attached

2. The similarities are;

a) Both circles can be described by a point and a radius or a diameter

The differences are;

a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)

b) The circumferences of the two circles are different

c) The area covered by the two circles are different

3. The circumference of the circle with radius equal to 3 cm is 2 × π × 3 = 6·π cm

The circumference of the circle with diameter equal to 3 cm is π × 3 = 3·π cm

Therefore, the circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm

4. The circumference to diameter ratio of the circle with radius = 3 cm is 6·π cm/(2 × 3 cm) = π

The circumference to diameter ratio of the circle with diameter = 3 cm is 3·π cm/(3 cm) = π.

Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter.

Answers

2/10 ———> simplified is D. 1/5

The turtle's rate in miles per hour is 1/5 miles/hr.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that a turtle traveled 1/10 miles in 1/2 hour.

Rate is defined as the distance travelled in a unit hour {1 hour}.{R} = x/t.

We can write the rate as -

{R} = (1/10)/(1/2)

{R} = (1/10) x 2

{R} = 1/5 miles/hr

Therefore, the turtle's rate in miles per hour is 1/5 miles/hr.
