What number Could be added in the expression -4 -9 that the value of the expression is 0

Answers

Answer:

+13

Step-by-step explanation:

-4-9 gives -13

when +13 is added to -13 , the expression becomes +13+(-13) =13-13=0

if i’m understanding this correctly -9 + -4 is equal to -13 so wouldn’t you just add 13 to make it 0?

Sum of the interior angles of any triangle equal 180° .

Thus ;

The angle which facing to the side 4 is 45°.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Hint:

In a right triangle, the side facing the 45° angle is √2 / 2 times the hypothenuse .

Thus ;

$( √(2) )/(2) x = 4 \n$

Multiply sides by 2

$2 * ( √(2) )/(2) x = 2 * 4 \n$

$√(2) x = 8 \n$

Divide sides by √2

$( √(2)x )/( √(2) ) = (8)/( √(2) ) \n$

$x = (4 * 2)/( √(2) ) \n$

$x = (4 * √(2) * √(2) )/( √(2) ) \n$

$x = 4 √(2) \n$

$x = hypothenuse = 4 √(2)$

Done...

Over the past several months, the water level of a lake has been decreasing by 3% each week. If the highest water level before the decrease started was 520 ft, what was the level at the end of 8 weeks?

Answers

Answer:

y= 407.54654 ft

Step-by-step explanation:

This is an exponential decay functions

y = ab^x where a is the initial value and b is ( 1 - rate of decay)

a = 520

b = 1- 3%

y = 520 ( 1- .3) ^x

y = 520 ( .97) ^x

We want x to be 8 weeks

y = 520 ( .97) ^8

y= 407.54654 ft

Share £360 in the ratio 2:7

Answers

Answer:

80:280

Step-by-step explanation:

Final answer:

To share £360 in the ratio 2:7, you first find the value of one part by dividing £360 by the total number of ratio parts (9). Then, multiply each part of the ratio by this amount, resulting in £80 and £280.

Explanation:

To share £360 in the ratio 2:7, you first need to understand that the sum of the parts of the ratio (2+7) equals to 9 parts. The amount of £360 should be distributed into these 9 parts.

First, you divide the total amount by the total number of parts:
£360 / 9 = £40.

This result £40 is the value of 1 part. To find the amounts for the ratio 2:7, you multiply each part of the ratio by the value of 1 part:
