Step-by-step explanation:

Since it is an open dot, it is not greater than or equal to, but rather just greater than.

10-root18/root2 = a+broot2

Sauron [17]

Step-by-step explanation:

$\frac{10 - \sqrt{18} }{ \sqrt{2} } = a + b \sqrt{2}$

$\frac{10}{ \sqrt{2} } + \frac{ - \sqrt{18} }{ \sqrt{2} }$

$5 \sqrt{2} + ( \frac{ - \sqrt{18} }{ \sqrt{2} } ) \times \sqrt{2}$

$a = 5 \sqrt{2}$

$b = \frac{ - \sqrt{18} }{ \sqrt{2} }$

M..................................find the value of x ...y and z..

My name is Ann [436]

Angle BCA = 180 - 100
angle BCA = 80

Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50

I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)

x = 180 - 50 = 130

A football stadium splits ticket sales in ratio of 3 : 4 between the away team and the home team. The home team make £36,000. Wh

<h3>Answer is 63,000 pounds</h3>

The ratio 3:4 means for every 3 pounds made in away team tickets versus home team tickets. Multiply both sides by 9000 to have that 4 turn into 36000. The ratio 3:4 will then turn into 27000:36000

With this new ratio, we see that the away team pulls in 27000 and the home team pulls in 36000. Add the two amounts to get the final answer

27000+36000 = 63000

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

We could alternatively add 3 and 4 (from the ratio 3:4) to get 3+4 = 7. Then multiply by that same scale factor 9000 getting 9000*7 = 63000.
