An account earns 3% yearly simple interest. How much interest will you earn in 5 years if you put $820 in the account
A. $130.60
B. $ 123.00
C. $943.00
D. $950.60

Answers

Answer 1

Answer:

[tex]the \: interest \: is \: 123.00(option \: b)[/tex]

Step-by-step explanation:

[tex]rate = 3\% \\ time = 5years \\ principal = 820[/tex]

[tex]interest = \frac{principal \: \times rate \: \times \: time}{100} [/tex]

[tex]interest = \frac{820 \times 5 \times 3}{100} [/tex]

[tex]the \: interest \: is \: 123[/tex]

Answer 2
The correct answer is B. $123

Answer:

[tex]225 {m}^{3} [/tex]

Step-by-step explanation:

To find the volume of the shape first we have to split the shape into two rectangles; a large one at the bottom and a small one at the top. The formula to find volume of a rectangle is

[tex]v = length \times width \times height[/tex]

note that after both volumes are found they should be added to determine the volume of the entire shape*

The length of the large rectangle is 5m, the width is 7m, and the height is 6m. Therefore the volume is

[tex]v = l \times w \times h \\ v = 5 \times 7 \times 6 \\ v = 210 {m}^{3} [/tex]

The length of the small rectangle is 5m, the width is 3m, and the height is 1m. Therefore the volume is

[tex]v = l \times w \times h \\ v = 5 \times 3 \times 1 \\ v = 15 {m}^{3} [/tex]

[tex]210 {m}^{3} + 15 {m}^{3} = 225 {m}^{3} \\ therefore \: the \: volume \: of \: the \: \\ entire \: shape \: is: \\ 225 {m}^{3} [/tex]

Answer:

[tex]V_{\ total}=225\ m^3[/tex]

Step-by-step explanation:

Step 1:  Find the volume of the big box

[tex]V_{\ big} = l * w * h[/tex]

[tex]V_{\ big} = 7\ m * 5\ m * 6\ m[/tex]

[tex]V_{\ big} = 210\ m^3[/tex]

Step 2:  Find the volume of the small box

[tex]V_{\ small} = l * w * h[/tex]

[tex]V_{\ small} = 3\ m * 5\ m * (7\ m - 6\ m)[/tex]

[tex]V_{\ small} = 3\ m * 5\ m * 1\ m[/tex]

[tex]V_{\ small} = 15\ m^3[/tex]

Step 3:  Combine the volumes

[tex]V_{\ total}=V_{\ big} + V_{\ small}[/tex]

[tex]V_{\ total}=210\ m^3 + 15\ m^3[/tex]

[tex]V_{\ total}=225\ m^3[/tex]

Answer: [tex]V_{\ total}=225\ m^3[/tex]

This table shows the results of rolling a standard number cube.
What is the approximate experimental probability of rolling a number less than 3?
Answer choices:
19%
17%
26%
33%

Answers

1) Correct option is C)

A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.

The experimental probability of getting a head is :

P(E)=

Total outcomes divided  by Number of head

58/100 = 29/50 (29/50x100) = 58% (C)

2) 19%​

​

Answer:

1. 42%

2. 33%

Step-by-step explanation:

1. Relative frequency = Number of successful trials ÷ Total number of trials

plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%

2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials

plug the numbers in and we get 2/6 = 1/3 = 33%

FEET 1 4 5
INCHES 24 36

Answers

Answer: feet: 1, 2, 3, 4, 5

          inches: 12, 24, 36, 48, 60

Step-by-step explanation:

There are 12 inches in a foot, therefore if you have 1 foot you have 12 inches, if you have 2 feet you have 24 inches becauase 2*12 = 24 and so on...

There are 12 inches in 1 foot. Therefore, 1 ft = 12 inches, 2ft=24 inches 3ft =36inches, and so on.
To find how many inches = the amount of feet you would simply multiply the number of feet by 12.
For example 4ft would be 4x12=48. Or 5ft would be 5x12=60
Therefore 4ft =48inches. And 5ft =60inches
If u are given an amount in inches to determine feet you would divide by 12
For example
84 inches into feet would be solved by dividing 84by 12
84/12=7
you now know that 84inches =7feet

which graph represent the liner function y= 1/3 x -4?

Answers

The answer would be this graph.

Answer:

Graph 3

Step-by-step explanation:

equation: y = mx + b → y = 1/3x - 4

- m is the slope (slope = rise / run):

- b is the y intercept (when x = 0): -4

Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4

Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1

the correct equation for this graph is y = 3x - 4

Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3

and the y intercept is -4

Graph 4 is incorrect because the y-intercept is not even shown

Step-by-step explanation:

The semi-perimeter is:

s = (a + b + c) / 2

= (10 + 24 + 26) / 2

= 47

We will find the area of the triangle using the Heron's formula.

A = √[s (s - a) (s - b) (s - c)]

= √[47 (47 - 10) (47- 24) (47 - 26)]

= √10 × 37 × 23 × 21

= √ 56513

Read the passage.excerpt from "A Cooking Revolution: How Clean Energy and Cookstoves Are Saving Lives" by Chef Jos Andrs, June 7, 2016Cooking: it's a simple act that has brought families around the world together for thousands and thousands of years.As a chef, I can think of few things more beautiful than that. However, I also know how deadly such a simple act can be , not only to our health, but to our environment.Think about it: For Americans, turning on the stove means simply turning a knob or switch. For people living in developing countries, particularly women and children, it means hours of collecting fuels like firewood, dung, or coal to burn in a rudimentary, smoky cookstove or over an open fire. The result is a constant source of toxic smoke that families breathe in daily, causing diseases like child pneumonia, heart disease, and lung cancer , not to mention taking a child away from her education.In fact, diseases caused by smoke from open fires and stoves claim 4.3 million lives every year. That's more than AIDS, malaria, and tuberculosis combined.And the environment suffers, too. When people collect wood every day from their local forests to create charcoal or fuel for wood-burning stoves, it creates an unsustainable pace of deforestation that leads to mudslides, loss of watershed, and other environmental consequences. These stoves also contribute up to 25 percent of black carbon emissions, a pollutant that contributes directly to climate change.You see, from what we cook to how we cook, our food connects with our lives on so many levels. That's why having access to better technology and clean energy for cooking is as equally important as the ingredients in the food being prepared.It's also why I'm proud to support an effort to bring clean cookstoves and fuels to millions of people in developing countries.Together with the United Nations, the U.S. government, and partners around the world, the Global Alliance for Clean Cookstoves focuses on working with local communities and organizations to develop a market for cookstoves and fuels that significantly reduce emissions, cook more efficiently, and fit with local customs and culture. . . .The Obama administration's investment goes a long way toward achieving our goal of bringing access to clean cookstoves and fuels to 100 million households in places like China, Guatemala, Kenya, and India by 2020.Just last month, India's Prime Minister Narendra Modi announced his plan to connect 50 million Indian families to clean cooking gas over the next three years. This is an important step being taken at an unprecedented scale, and it could help protect the lives of millions and while also improving India's environment.That's powerful, people! Mothers can be healthier. Young girls have more time to go to school. Forests grow again. People can feed themselves without risking their lives to cook a meal.That's what we can accomplish by providing clean cookstoves and fuels. And that's a simple act that can change the world for years and years to come.What is the author's main purpose for writing about problems and solutions in this passage?A) to further understanding about the negative impact of smoke on healthB) to explain why countries are unable to address the problems caused by cookingC) to describe issues related to cooking in many developing countriesD) to compare what various countries are doing about issues related to cooking (3+7) (3-7) pl and me in 130,426 the digit 2 is in the _____ place?
