Answer:

The area of the irregular shape is 20 square cm

Step-by-step explanation:

Area of an Irregular Shape

Some shapes do not have regular shapes like squares, circles, triangles, etc. where well-known formulas can be applied to calculate their areas.

We have to calculate the area of the shape provided in the figure. We have divided the shape into three rectangles (see figure below). The total area of the irregular shape is:

A = A1 + A2 + A3

The first rectangle has dimensions 2 cm by 1 cm, thus its area is:

A1 = 1 cm * 2 cm = 2 square cm

The second rectangle has dimensions 2 cm by 3 cm, thus its area is:

A2 = 2 cm * 3 cm = 6 square cm

The third rectangle has dimensions 3 cm by 4 cm, thus its area is:

A3 = 3 cm * 4 cm = 12 square cm

The total area is:

A = 2 square cm + 6 square cm + 12 square cm = 20 square cm

The area of the irregular shape is 20 square cm

Three consecutive integers add up to -36. What are the integers?

nasty-shy [4]

Answer:

We know our answer is correct because 11 + 12 + 13 equals 36 as displayed Below

Explanation

3X + 3 = 36 3X + 3 - 3 = 36 - 3 3X = 33 3X/3 = 33/3 X = 11 Which means that the first number is 11, the second number is 11 + 1 and the third number is 11 + 2. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36 We know our answer is correct because 11 + 12 + 13 equals 36 as displayed above. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36

The sum of −7 times a number and 8 times the sum of the number and 1 is the same as the number minus 7.

Novay_Z [31]

Answer:

n has no value.

There is no solution to this equation

Step-by-step explanation:

let n be the number

In pieces:

sum of the number and 1: (n + 1)

8 times the sum: 8(n + 1)

-7 times a number: -7n

sum of -7 times and...: -7n + 8(n + 1)

number minus 7: n - 7

the same as: =

All together:

-7n + 8(n + 1) = n - 7

-7n + 8(n+1)=n-7

-7n + 8n+8=n-7

Dianna has 4 quarters, 3 dimes, and 3 nickels in her purse. She reaches into her purse and randomly grabs two coins, one at a ti

Galina-37 [17]

At the beginning there are 3 dimes out of 10 coins:
P(first coin is a dime) = 3/10

After that there are 3 nickels out of 9 remaining coins:
P(second coin is a nickel) = 3/9 = 1/3

P(dime, then nickel) = P(first coin is a dime) x P(second coin is a nickel)
= 3/10 x 1/3
= 1/10

Answer:
1/10 . if im wrong im sorry
