Mr. Hamilton surveyed his class to find the total number of hours each of his students slept the previous night. The histogram shows the results of the survey.

What percentage of Mr. Hamilton’s students slept 12 hours or more?

Answer:

0.18 cm²

Step-by-step explanation:

Given that a rectangle and a triangle have same perimeter . The sides of them are ,

[tex]\begin{cases} Square = 4cm , 4cm , 3cm \ and \ 3cm .\\ Triangle = 4cm , 5.8cm \ and \ 4.2cm \end{cases}[/tex]

We know that area of rectangle is product of length and breadth.

[tex]\implies Area = length \times breadth \\\\\implies Area = 4cm \times 3cm\\\\\implies \red{ Area = 12cm^2}[/tex]

Also we know that the area of triange is half the product of base and height . So that ,

[tex]\implies Area = \dfrac{1}{2}\times 5.8cm \times 4.2 cm \\\\\implies \red{ Area = 12.18 cm^2 }[/tex]

Therefore the difference between them is ,

[tex]\implies D = A_1 - A_1 \\\\\implies D = 12.18cm^2-12cm^2 \\\\\implies \red{D = 0.18 cm^2}[/tex]

1. remote interior angles

2. interior angles

3. supplementary angles

4. exterior angles

Answer:

(Page 1):

1.) 150°

2.) 25°

3.) 120°

4.) 60°

(Page 2):

1.) 180 - (40 + 30) = 110°

2.) 180 - (33 + 92) = 55°

(Page 3 doesn't show questions all the way)

Step-by-step explanation:

(Page 1):

1.) ∠1 and ∠2 are Straight angles which make up 180° if added up together => 180° - 30° = ∠2

2.) ∠5 and ∠8 are Vertical angles which means they are congruent ,             => if ∠5 = 25 then so will ∠8.

3.) By the opposite side alternate interior angles theorem ∠6 is congruent to ∠3,      

=> if ∠6 = 120, then ∠3 = 120

4.) if there is a set of an exterior angle and an interior angle, they both add up to 180°.

=> 180° - 120° =  ∠4

Answer:

there is 3 vowels

Step-by-step explanation:

The ratio of the total number of vowels to letters in word eleven is 1:2

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"

Given here the word eleven where the number of vowels is 3 and total letters is 6

∴ 3:6=1:2

Hence, The ratio of the total number of vowels to letters in word eleven is 1:2

Answer:

I thought it was 1/9

Step-by-step explanation:

favorable out comes are 4

and total out comes are 36

The probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happeing of the event.

We have:

Elena rolls two cubes numbered 1 to 6.

The total outcome = 6×6  

As there are two cubes with each cubes numbered 1 to 6

Total number of favourable outcomes = 4

Which are (3, 6), (4, 5), (5, 4), and (6, 3)

Now the probability P will be:

[tex]\rm P = \frac{4}{36}[/tex]

[tex]\rm P = \frac{1}{9}[/tex]

Thus, the probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.
