Answer 1

Answer: Well, we can really show our work because their is no work to be done. Question 7 is a right angle because it is exactly 90 degrees. So since you now know what a right angle is, you can probably guess Question 8 a would be either 3 o'clock or 9 o'clock. For question 8b , he first one, and acute angle is an angle where it is below 90 degrees. So an example of an acute time is 3:05. An obtuse angle is an angle above 90 degrees. So an obtuse time would be (for example) 3:55. Hope this helped.

Hannah has a grid of squares that had 12 rows with 15 squares in each row. She colors 5 rows of 8 squares in the middle of the grid blue. She colors the rest of the squares red. How many squares does Hannah color red?

Answers

there's a grid of squares with 12 rows and in each row there are 15 squares

from this grid she colours 8 squares from each row for 5 rows blue.

the rest of the squares she colours red

so first we have to find how many squares are there in the grid in total

so if each row has 15 squares

then 12 rows have - 15 x 12 = 180 squares

blue coloured squares

she colours 8 rows of 5 squares

so if 1 row has - 5 squares

then 8 rows have - 5 x 8 = 40 squares

from 180 squares, she colours 40 squares blue and the rest red colour

therefore the squares she colours red are

red squares = 180 - 40 = 140 squares

she colours 140 squares red

WORK:
12 rows of 15 squares = 12 × 15 = 180 squares
5 rows of 8 squares = 5 × 8 = 40 squares
180 squares - 40 squares = 140 squares
ANSWER:
Hannah colors 140 squares red.

How do I solve this problem? 4/9 + 2 =

Answers

you first put a 1 under the 2
than you give them the same denominator(bottom number)
that is 18/9 and 4/9
Now add them together and get 22/9
now make that into a mixed-number by dividing 22 by 9 you get 2.44

So...4/9+2 =2.44

Hope this helps

Write all names that apply to 121/√121

Answers

Answer:

Natural, Whole, integer, rational, real

Step-by-step explanation:

Here, the given number,

$(121)/(√(121))$

We can write,

$(121)/(√(121))=(121)/(11)$

∵ 121 and 11 are integers also, 11 ≠ 0,

So, $(121)/(11)$ is a rational number,

⇒ $(121)/(√(121))$ is a rational number,

Now,

$(121)/(11)=11$

11 is a whole number,

⇒ $(121)/(√(11))$ is a whole number,

Again, a whole number is always a natural number and a positive integer ,

⇒ $(121)/(√(11))$ is a natural number or an integer,

All numbers ( rational or irrational ) are called real number.

So, we can also write,

$(121)/(√(121))$ is a real number.

Giraffes are the tallest land animals. A male giraffe can grow 6 yards. How tall would the giraffe be in feet?

Answers

If a yard is three feet, then you need to multipy 3 by 6.

6 x 3 = 18

So a giraffe would be 18 feet tall.

I think it might be 19 feet maybe?
