A rope.Measure 60cm was divided into 2 groups . 1 was used to make a rectangle of length 12cm and breadth 6cm. And the other was used to make a hexagon . What is the size of the hexagon in each side

Answers

Answer 1

Answer:

4cm

Step-by-step explanation:

Firstly, we need to know the perimeter of the rectangle so as to know the length used to make the rectangle. This is 2(l + b)

P = 2(12 + 6) = 2(18) = 36cm

The length remaining to make the hexagon would be 60 - 36 = 24cm

Now since the hexagon is regular, the length of each side would be 24/6 = 4cm

Note: hexagon is a polygon with 6 sides

Select from the choices below, dragging and dropping to build an inequality that could be used to determine when Martin's comic book
collection exceeds Beth's

Answers

Answer:

The answer to your question is 250 - 20 < 80 + 15x

Step-by-step explanation:

Data

Beth has 250 books and sells 20 each week

Martin has 80 books and sells 15 each week

week = x

Process

1.- Write an equation for each situation

Beth 250 - 20x

Martin 80 + 15 x

2.- Write the inequality

250 - 20 < 80 + 15x

Amir arranged 9 photos on a bulletin board. He put the photos in rows. Each row contains the same number of photos. How many photos could be in each row?

Answers

Answer: There will be 3 rows with 3 photos.

Step-by-step explanation:

Since we have given that

Number of photos to be arranged by Amir on a bulletin board = 9

According to question, we have given that each row contains the same number of photos.

Let the number of rows be x

So, the number of photos also be x

So, our equation becomes

$x^2=9\n\nx=√(9)\n\nx=3$

So, there will be 3 rows with 3 photos.

three rows of threes

The sum of 1/9 2/3 and 5/18 is what

Answers

So first we have to find a common denominator, in this case it is simple because 18 works. So now we have to make 1/9 into ?/18, to do this we multiply 1/9 by 2, so now we have 2/18 + 2/3 + 5/18. To make 2/3 into ?/18 we have to multiply by 6, so now we have 2/18 + 12/18 + 5/18. Now you add all the numerators (top numbers) together and we get 19/18, which is the same as 1 1/18

ANSWER: 19/18 or 1 1/18.

Feel free to ask any questions about my explanation if you need it(:

The sum of the fractions $(1)/(9),(2)/(3),\frac{5}{{18}}$ is $\boxed{\frac{{{\mathbf{19}}}}{{{\mathbf{18}}}}}$ .

Further explanation:

Given:

The given fractions are $(1)/(9),(2)/(3),\frac{5}{{18}}$ .

Step by step explanation:

Step 1:

First we make the denominator same of the given fraction.

The equivalent fraction of $(1)/(9)$ can be calculated as,

$\frac{{1 * 2}}{{9 * 2}} = \frac{2}{{18}}$

The equivalent fraction of $(2)/(3)$ can be calculated as,

$\frac{{2 * 3}}{{3 * 3}} = (6)/(9)$

The equivalent fraction of $\frac{5}{{18}}$ can be calculated as,

$\frac{{5 * 1}}{{18 * 1}} = \frac{5}{{18}}$

Step 2:

We know the sum of the given fractions and the sum of the equivalent fractions would be same.

Now find the sum of the equivalent fraction to find the sum of the given fractions $(1)/(9),(2)/(3),\frac{5}{{18}}$ as,

$\begin{aligned}\frac{2}{{18}} + \frac{{12}}{{18}} + \frac{5}{{18}} &= \frac{{2 + 12 + 5}}{{18}} \n&= \frac{{19}}{{18}} \n\end{aligned}$

Therefore, the sum of the fractions $(1)/(9),(2)/(3),\frac{5}{{18}}$ is $\frac{{19}}{{18}}$ .

Akiba Ellis deposits the following in her checking account: 6 five-dollar bills, 5 two dollar bills, 12 one dollar bills, 9 half dollars, 6 quarters, 42 dimes, 10 nickels, 15 pennies, and a check for $97.23. what is her total deposit?

Answers

Answer:

$106.08

Step-by-step explanation:

Given:

6x $5.00

5x $2.00

12x $1.00

9x= 0.50

6x25 cent

42x10 cent

10x5 cent

15=15cent

$97.23

----------------------------------------------------------------------------------

6 five dollar bill is $30.00

so 5 two dollar bill is $10.00

12 one dollar bills is $12.00

9 half dollar bill mean 0.50 cent since it Half and that would make $4.50

6 quarter so 6x25 which equal $1.50

42 dimes and dimes =10 cent so 42x10 which equal $4.20

10 nickels and nickels = 5 cent so 10x5=0.50

15=15 pennies

-------------------------------------------------------------------------------------

30.00+10.00+12.00+4.50+1.50+4.20+0.50+0.15+97.23 =
