Pls HelpWith The Second One A And B And The Triangle

Answers

Answer 1

Answer:

the new side lengths are 10.5 , 9 and 6 inches

the new triangle has the following sides: 5, 4, 3 inches

the perimeter of the first triangle is 36 inches

the perimeter of the second triangle is 12 inches

area of the first triangle is 54 inches squared

area of the second triangle is 6 inches squared

Step-by-step explanation:

first question:

sides are 7,6,4. multiply each one by 3/2 or 1.5

7 x 1.5 = 10.5 or 12/2

6 x 1.5 = 9

4 x 1.5 = 6

the new side lengths are 10.5 , 9 and 6 inches

second question:

multiply each side by 1/3

the sides are 15, 12, 9, so:

15 x 1/3= 5

12 x 1/3 = 4

9 x 1/3 = 3

the new triangle has the following sides: 5, 4, 3

normal sides are 3 and 4

hypotenuse is 5

question a: (calculate perimeter)

the perimeter of a triangle: you add all the sides

the first triangle has 15, 12, 9 for its sides so:

15+12+9 = 36

the perimeter of the first triangle is 36

the second triangle has 5,4,3 for its sides so:

5+4+3 = 12

the perimeter of the second triangle is 12

question b: (calculate the area of both triangles)

area of a triangle: h x b/2: height times base divided by 2

the first triangle has sides, 15,12,9

height is 9 and base is 12, so:

9 x 12/2 = 54 inches squared

area of the first triangle is 54 inches squared

the second triangle has sides, 5,4,3

height is 3 and base is 4, so:

3 x 4/2 = 6 inches squared

area of the second triangle is 6 inches squared

On a multiple-choice test with five possible answers for each question, what is the probability of answering a question correctly if you make a random guess? (write your answer as a decimal).

Answers

The probability of answering correctly if you make a random guess is:

P = 1/5 = 0.2

How to find the probability for a random guess?

If you make a random guess, then you have no idea of which could (or couldn't) be the correct answer. Thus, all the 5 options have the exact same probability of being the correct one.

From this, the probability of answering correctly the question is given by the quotient between the number of correct answers (we assume is only one) and the total number of options (5).

So the probability is:

P = 1/5 = 0.2

We know that:

Tank = 4 liters2/3 x 4 = Water filled in tank

Multiply both the terms to get the answer.

Solution:

2/3 x 4 liters=> 8/3 liters = 2 2/3 liters

Hence, 2 2/3 liters has been filled with water.

paul graphs the equation y = 2x where does the graph intersect the y axis

Answers

Answer:

(0,0)

Step-by-step explanation:

Y = 2x is a proportional relationship because it follows the form y = kx, where k = constant of proportionality. Proportional relationships intersect the y-axis at (0,0), thus having a y-intercept of 0, but we usually don't write the 0.

Given the information above, y = 2x intersects the y-axis at (0,0), the origin.

I need help with problem 11

Answers

I really don’t know gang but be strong you can do it

Answer:

x = 68

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is: (n - 2) x 180° (where n is the number of sides)

This polygon has 5 sides, so the sum of the interior angles:

(5 - 2) x 180° = 540°

To find x, add together all the angle expressions, equate to 540 and solve for x:

                                                       U + V + W + Y + Z = 540

                       (x - 8) + (3x - 11) + (x + 8) + x + (2x + 7) = 540

Gather like terms:  x + 3x + x + x + 2x - 8 - 11 + 8 + 7 = 540

Combine like terms:                                           8x -4 = 540

Add 4 to both sides:                                               8x = 544

Divide both sides by 8:                                             x = 68

     r = 66/2π =10.509554140127

Area of circle  = πr²   = 3.14(10.509554140127)²

Andy, Bert, and Charles have 20 pieces of chocolate. Some of the chocolates have nuts, some are plain, and some are filled with caramel (they are split in a ratio of 1:2:2, respectively). Neither Andy nor Charles can eat nuts, and Charles will always take caramels over plain chocolates if he can (the others are indifferent to plain or caramels). If Andy, Bert, and Charles split the chocolates among themselves in a ratio of 3:1:1, respectively, in a way that makes each person as happy as possible, how many pieces of chocolate with caramel does Andy receive?

Answers

Answer: 4

The ratio in which the chocolates are divided into types can be seen as splitting the chocolates into 1+2+2 = 5 equal parts. Since there are 20 chocolates, each part corresponds to 20/5 = 4 chocolates. Thus, there are 1*4=4 chocolates with nuts, 2*4=8 plain chocolates, and 2*4=8 chocolates with caramel. Now, the three boys are dividing the chocolates into 3+1+1 = 5 equal parts. Thus, each part again corresponds to 4 chocolates. So, Andy will receive 3*4=12 chocolates, Bert will receive 1*4=4 chocolates, and Charles will receive 1*4=4 chocolates. Because neither Andy nor Charles can eat nuts, and there are four chocolates with nuts, and Bert receives four chocolates, Bert must take all of the chocolates with nuts. Charles receives four chocolates total, and, since he prefers caramel, he will take four of the eight caramels. This leaves eight plain chocolates and four caramels to make up Andy's twelve chocolates. Thus, Andy receives 4 pieces of chocolate with caramel.

What is 1 19/100 as a decimal?

Answers

1.19

Explanation:
Uhh well… 1 19/100 is the same as 119/100 so just do 119 divided by 100…
And then you’ll get 1.19 which is 1 19/100 as a decimal.
Hope this helps!

Answer: 1.19

Step-by-step explanation: To convert this mixed number (fraction) to a decimal just follow these two steps:

Step 1: divide numerator (19) by the denominator (100): 19 ÷ 100 = 0.19

Step 2: add this value to the the integer part: 1 + 0.19 = 1.19. So,

1 19/100 = 1.19

Rounded values:

1 19/100 = 1 rounded to 0 decimal places

1 19/100 = 1.2 rounded to 1 decimal place1

Juan is building a doghouse he purchased 14-foot long board if there inches in one foot how long is the board in inches Andy Warhol was one of the most popular artists of his time. His playful style of painting and approach to creating "pop" art made him fashionable and well liked. Warhol's inspiration to become an artist started when he was eight years old. During that time, he became sick and spent a lot of time in bed because of illness. His mother was an artist and gave him drawing lessons to keep him occupied and lift his spirits. He soon discovered that he loved drawing. He also became a fan of film and photography, which helped him realize how much he wanted art to be an important part of his life. Warhol's art career officially began in the 1950s, when he worked as a magazine illustrator and graphic designer in New York City. While working at Glamour, a popular fashion magazine, he became well known for his unique style of photography and quirky handwriting. In the early 1960s, he began to show more interest in painting. Andy experimented with creative new techniques. He started by making paintings that looked like comics and advertisements. Eventually, he began painting common objects in a pop art style. People became fascinated with his work because it was a very different style of art from what they were used to. Warhol painted everyday things such as vacuum cleaners and soup cans. His paintings of ketchup bottles and hamburgers received a lot of attention. Warhol did not just paint. He made art in various mediums and experimented with film and television. However, his popularity greatly grew when he started painting famous people. He painted celebrity portraits of Marilyn Monroe, Elvis, and Mick Jagger. Eventually, celebrities started offering Warhol a great deal of money to paint their portraits. Musicians, wealthy socialites, and film stars were very eager to be painted by the ultra-talented Warhol. Painting celebrities was very profitable, and it became his main source of income. Some of his paintings sold for millions of dollars. Today, some of Warhol's paintings are considered some of the most valuable pieces of art in the world.
