A spring has spring constant 0.3 m/newton. What force is necessary to stretch the spring by 1.5 meters?

Answers

Answer 1

If 1 newton pushes it 0.3 meters, it would take 1.5 / 0.3 newtons, or 5 newtons to push it 1.5 meters

Answer 2

Answer: 5 Newton

Step-by-step explanation:

We know that the Hooke's law states that the force 'F' needed to stretch or compress a spring by some distance 'a' is proportional to that distance .

[tex]F=\dfrac{a}{c}[/tex], where c is the spring constant.

Given: A spring has spring constant 0.3 m/newton.

The  force is necessary to stretch the spring by 1.5 meters is given by :-

[tex]\Rightarrow\ F=\dfrac{1.5}{0.3}\\\\\Rightarrow\ F=5[/tex]

Hence, the  force is necessary to stretch the spring by 1.5 meters = 5 Newton .

What is sin 74° someone please help!!!!

Answers

Answer:

24/25

Step-by-step explanation:

because of sinФ you use the opposite/hypotenuse to get 24/25

The value of sin 74° in the given question is 24 / 25.

What is the sine angle?

The sine of an angle in a right angled triangle is the ratio of side opposite to the angle and the hypotenuse of the triangle.

In the given question:

Side opposite to 74° angle = 24

Hypotenuse of the triangle = 25

sin(74) = Perpendicular / Hypotenuse

sin(74) = 24 / 25

Hence, the value of sin74 is 24/25.

Patty buys a carpet that is made up of 9 parallelograms. Each parallelogram has a base of 12 inches and a height of 20 inches. The area of each parallelogram is square inches. The area of the carpet is square inches. HELP BRAINLIEST

Answers

The area of each parallelogram is 240 square inches, and the area of the carpet is 2,160 square inches.

The area of each parallelogram

The dimension of the parallelograms is given as:

Base = 12 inches

Height = 20 inches

The area of the parallelograms is calculated as:

Area = Base * Height

So, we have:

Area = 12 * 20

Area = 240 square inches

The area of the carpet

The area of each parallelogram is calculated as:

Area = 240 square inches

The number of parallelograms is given as:

n = 9

So, the area of the carpet is:

Carpet = 9 * 240 square inches

Evaluate

Carpet = 2160 square inches

Hence, the area of the carpet is 2160 square inches

https://brainly.com/question/14137384

Final answer:

To find the total area of Patty's carpet, multiply the area of one parallelogram (base 12 inches, height 20 inches) by the number of parallelograms (9), resulting in a total area of 2160 square inches.

Explanation:

To calculate the area of a parallelogram, the formula is base times height. In the given question, each parallelogram has a base of 12 inches and a height of 20 inches.

So, the area of one parallelogram is:

Area = Base × Height = 12 inches × 20 inches = 240 square inches.

Since Patty's carpet is made up of 9 parallelograms, we multiply the area of one parallelogram by 9 to find the total area of the carpet:

Total area = 240 square inches × 9 = 2160 square inches.

Therefore, the total area of the carpet is 2160 square inches.

Suppose you buy a CD for $11.95. There is a 20% discount, and you pay a 7% sales tax after the discount. Find the cost of the CD.

Answers

You can use proportions to find the answer.

20/100=?/11.95

20*11.95=239

239/100=2.39

So the discount takes $2.39 off of the original price.

11.95-2.39=9.56

7/100=?/9.56

7*9.56=66.92

66.93/100=0.6692

Round to nearest tenth: 0.67

9.56+0.67=10.23

The final cost of the CD is $10.23

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies.
How many chocolate chips were in each pan of brownies?
Write your answer as an expression.

Answers

Answer:

Each pan of brownies had [tex]\frac{400-x}{3} = \frac{400}{3}-\frac{x}{3}[/tex] chips

Explanation:

Savannah originally had 400 chocolate chips

Now, she saved x chocolate chips for garnish

This means that the amount she originally had decreased by x

Savannah now has 400-x chocolate chips to use for brownies

She divided this amount evenly into three pans. This means that the amount in each pan will be equal to the amount she has now divided by 3

This means that:

Each pan got [tex]\frac{400-x}{3} = \frac{400}{3}-\frac{x}{3}[/tex] chips

The table below models the cost, y, of using a high-efficiency washing machine and a standard washing machine over x number of years.

Answers

Answer:

i) y = 25x + 500

ii) y = 30x + 400

iii) The washing machines would cost the same amount after 20 years of use

iv) Standard machine

Step-by-step explanation:

i)

We are to determine a straight line equation that models the cost of High-Efficiency washing machine over the years;

The first step step is to determine the slope of the line,

( change in y) / ( change in x ) = (550 - 525) / ( 2 - 1) = 25

The equation is slope-intercept form will be;

y = 25x + c

Where y is the cost of the High-Efficiency washing machine and x the number of years. To determine the y-intercept, c, we use any pair of points given in the data table;

when x = 1, y = 525

525 = 25(1) + c

c = 500

Therefore;

y = 25x + 500

ii)

The straight line equation that models the cost of Standard washing machine over the years;

Slope = (460 - 430) / (2 - 1) = 30

The equation is slope-intercept form will be;

y = 30x + c

when x = 1, y = 430

430 = 30(1) + c

c = 400

Therefore;

y = 30x + 400

Where y is the cost of the standard washing machine and x the number of years.

iii)

Given the cost functions for both machines over the number of years, we simply equate the two equations and determine the value of x when both machines would cost the same amount;

We have the cost functions;

y = 25x + 500

y = 30x + 400

Equating the two and solving for x;

25x + 500 = 30x + 400

500 - 400 = 30x - 25x

100 = 5x

x = 20

Therefore, the washing machines would cost the same amount after 20 years of use.

iv)

In order to determine which machine would be the more practical purchase if kept for 9 years we use the cost functions obtained in i) and ii)

The cost function of the High-Efficiency washing machine is;

y = 25x + 500

To determine the cost, we solve for y given x = 9

y = 25(9) + 500

y = 725

The cost function of the Standard washing machine is;

y = 30x + 400

We solve for y given x = 9

y = 30(9) + 400

y = 670

Comparing the two values obtained, the cost for the Standard washing machine is more practical.

1) y=25x+500

2) y=30x+400

3) 20

4) standard machine

48+6x-28+2x = 180

Combine like terms

20+8x =180

Subtract 20 from each side

8x = 160

Divide each side by 8
