kakasveta [241]

The answer is rhombus because first of all it is the only one who has no right triangle. Its also did not say that it has parallel sides. Plus it has 4 sides which means its a rhombus

In a board game, you must roll two 6-sided number cubes. You can only start the game if you roll a 3 on at least one of the numb

Maru [420]

A) You can have

1-1; 1-2; 1-3; 1-4; 1-5; 1-6; 2-2; 2-3; 2-4; 2-5; 2-6; 3-3; 3-4; 3-5; 3-6; 4-4; 4-5; 4-6; 5-5; 5-6; 6-6

Those are all possible outcomes

B) Only 6 of the options include at least one three

The fraction is: 6/21 or simplified 2/7

C) To find this answer we need a percentage

to find that...

6/21 and ?/100

(When writing put it as a fraction to visually see the next part)

We will cross-multiply: the ? will be represented by x

(6 times 100) + (21x)

600 = 21x

Now divide 600 by 21 to get about 28.6

Since 28.6 < 34 then we would get a probability of less than 34 out of 100

The lengths of a rectangle have been measured to the nearest tenth of a centimetre they are 87.3cm and 51.8cm what is the upper

vagabundo [1.1K]

Answer: Area (upper bound) = 4527.7056 cm²

Perimeter (lower bound) = 278 cm

Step-by-step explanation:

The length and width of the rectangle have been ROUNDED to the nearest tenth. Let's calculate what their actual measurements could be:

LENGTH: rounded to 87.3, actual is between 87.25 and 87.34

87.25 is the lowest number it could be that would round it UP to 87.3

87.34 is the highest number it could be that would round DOWN to 87.3

WIDTH: rounded to 51.8, actual is between 51.75 and 51.84

51.75 is the lowest number it could be that would round it UP to 51.8

51.84 is the highest number it could be that would round DOWN to 51.8

To find the Area of the upper bound, multiply the highest possible length and the highest possible width:

A = 87.34 × 51.84 = 4527.7056

To find the Perimeter of the lower bound, calculate the perimeter using the lowest possible length and the lowest possible width:

P = 2(87.25 + 51.75) = 278
