Answer:

Yes I agree with Ariel

Step-by-step explanation:

As to work out percentages you would divide by 100 and time by amount

as cent means 100

so  it would be 10/100*10=£10

so if she withdraws £10 every Friday for 10 withdraws then her bank account would be empty7 after 10 withdraws

Hope this explained it ok and helped you

Y_Kistochka [10]

Answer:

the height of the tree is <em>15.49 m</em>

<em></em>

Step-by-step explanation:

Step 1:

From the figure, we can determine ∠ATB by using the fact that the sum of all the angles in a triangle add up to 180°:

∠ ATB  = 180° - 98° - 20°

∠ ATB = 62°

Step 2:

Therefore, using the law of sines, we can determine the height of the tree.

TB / sin(20°)  = 40 / sin(62°)

TB = 40 × (sin(20°) / sin(62°))

<em>TB = 15.49 m </em>

<em></em>

Therefore, the height of the tree is <em>15.49 m</em>

Which table has a constant of proportionality between yyy and xxx of 101010?
Gnesinka [82]

Answer:

Only table C shows proportional relationship

Step by Step Explanation:

Given

Tables A, B an C

Required

Which table shows proportional relationship?

In table A .

x = 2 and y = 20

k = 20/2

k = 10

Also, x = 12, y = 132

k =. 132/12.

k = 11

Both values of k are not equal.

Hence, the table is not proportional

In table B

x = 5 and y = 20

k = 20/5

k = 4

Also, x = 7, y = 30

k =. 30/7

k = 4.29

Both values of k are not equal.

Hence, the table is not proportional

In table C

x = 9 and y = 90

k = 90/9

k = 10

Also, x = 14, y = 140

k =. 140/14

k = 10

Also, x = 24, y = 240

k =. 240/24

k = 10

All values of k are equal.

Hence, the table is proportional
