Please answer this question, and happy valentines day!! &lt;3
tino4ka555 [31]

Given:

The two ways table.

To find:

The number of girls in year 9.

Solution:

Using the two ways table, we get

Boys in year 10 = Total student in year 10 - Girls in year 10

                        = 256 - 123

                        = 133

Boys in year 9 = Total boys - Boys in year 10 - Boys in year 11

                        = 407 - 133 - 125

                        = 149

Girls in year 9 = Total students in year 9 - Boys in year 9

                       = 303 - 149

                       = 154

Therefore, the number of girls in year 9 is 154 and the correct option is C.

What is the length of CD in this diagram, ABC - EDC,
natima [27]

Answer:

<h2>4</h2>

Option A is the right option.

solution,

∆ABC~∆EDC

\frac{bc}{cd}  =  \frac{ac}{ec}  \\  \:

putting the values,

\frac{20 - x}{x}  =  \frac{20}{5}  \\  or \: 5(20 - x) = 20x(cross \: multiplication) \\ or \: 100 - 5x = 20x \\ or \:  - 5x - 20x =  - 100 \\ or \:  \:  - 25x =  - 100 \\  \: or \: x =  \frac{ - 100}{ - 25}  \\ x = 4

Hope this helps..

Good luck on your assignment..

If a &gt; b &gt; c &gt; d, then which is larger, a+c or b+d ? Can we tell from a &gt; b &gt; c &gt; d which of a+d and b+c is la
victus00 [196]

Answer:

1. a+c is larger than b+d

2. No way to tell whether a+d or b+c is larger.

Step-by-step explanation:

<u>1. Which is larger, a+c or b+d?</u>

Let a, b, c, and d be any numbers such that a > b > c > d.

Specifically, note that a > b, and subtracting b from both sides of the inequality, observe that a-b > 0.

Similarly, c > d, and subtracting d from both sides of the inequality, observe that c-d > 0.

From this, <u>add "a-b"</u> (a positive number, as proven above) to both sides of the inequality.

(a-b)+(c-d) > (a-b)+0

Addition by zero (<u>the additive identity</u>) doesn't change anything, so the right side remains "a-b"...

(a-b)+(c-d) > a-b

... and <u>"a-b" is positive</u>...

(a-b)+(c-d) > a-b > 0

... so, by the <u>transitive property</u> of inequality...

(a-b)+(c-d) > 0

Recall that <u>subtraction is addition by a negative</u> number...
a+(-b)+c+(-d) > 0

...and that <u>addition is associative and commutative</u>, so things can be added in any order, so the middle two terms on the left side can be rearranged...

a+c+(-b)+(-d) > 0

<u>Adding b + d</u> to both sides of the inequality

(a+c+(-b)+(-d))+(b+d) > 0+(b+d)

... and <u>simplifying</u>

a+c > b+d

So, a+c is larger than b+d.

<u>2. Which is larger, a+d or b+c?</u>

Consider the following two examples:

<u>Example 1</u>

Suppose a=10; b=3; c=2; d=1.

Note that a > b > c > d (10 > 3 > 2 > 1) and, also observe that a+d=(10)+(1)=11, and b+c=(3)+(2)=5, so a+d is larger than b+c.

<u>Example 2</u>

However, suppose a=10; b=9; c=8; d=1.

Note that a > b > c > d (10 > 9 > 8 > 1) but that a+d=(10)+(1)=11, and b+c=(9)+(8)=17, so a+d is smaller than b+c.

So, in one example, a+d is bigger, and in the other, a+d is smaller.  Therefore, there is no way to tell which of a+d or b+c is larger from only the given information.

The area of a rectangle is 45 cm2. Two squares are constructed such that two adjacent sides of the rectangle are each also the s
lorasvet [3.4K]

Answer:

The length of sides of one square is 5cm  and length of sides of another square is 9cm

Step-by-step explanation:

Let the length of rectangle be x and width of rectangle be y.

We have given,

Area of rectangle = 45 cm²

i.e. Area of rectangle = x·y = 45  or xy = 45   ---------(1)

Next, two squares are constructed from two adjacent sides of rectangle.

i.e Side length of one square will be x and side length of another square will be y.

Area of one square = x²

And area of another square = y²

According to problem,

Sum of area of two squares is 106 cm²

∴ x²+y² = 106   ---------------(2)

From equation (1) and (2) , we can find x and y.

xy = 45  or x = \frac{45}{y}  , Plug this in equation (2).

We get,

x² + y² = 106

or (\frac{45}{y} )^{2} + y^{2} =106

or \frac{45^{2} +y^{4} }{y^{2} } =106

or 45^{2} + y^{4} = 106y^{2}

On solving this equation we get ,

y²=81 or 25

or y = 9 or 5

for y =9 , x= \frac{45}{9} =5

or for y = 5 , x = \frac{45}{5} =9

Hence the length of sides of one square is 5cm  and length of sides of another square is 9cm
