Look for the adjacent letters A.F or F.A in the names of the pair of angles.

The appropriate choice is ...

Answer:

BAF and FAD

Step-by-step explanation:

In order for an angle to have A.F as a side, it must have the letters A.F or FA in its name.

In DAF, the angle is made of rays AD and A.F. In DAB, the angle is made up of rays AD and AB. This is not the correct pair.

In EAF, the angle is made of rays AE and A.F. In CAE, the angle is made up of rays AC and AE. This is not the correct pair.

In BAF, the angle is made of rays AB and A.F. In EAD, the angle is made up of rays AE and AD. This is not the correct pair.

In BAF, the angle is made up of rays AB and A.F. In FAD, the angle is made up of rays A.F and AD. This is the correct pair.

When a watch is sold at ksh 126 aloss of x percent is made . If the same ksh 126, a loss of x percent is made . If the same watc

Nitella [24]

Answer:

ksh 140

Step-by-step explanation:

When a watch is sold for ksh 126 a loss of x% is made, that is( 100 - x)%

Hence, the loss amount = (126 X 100)/(100 - x)

When the same watch is sold for ksh 154 a profit of x% is made, that is (100 + x)%

Hence, the profit amout = (154 X 100)/(100 + x)

Therefore, (126 X 100)/(100 - x) = (154 X 100)/(100 + x)

12600(100 + x) = 15400(100 - x)

1260000 + 12600x = 1540000 - 15400x

28000x = 280000

x = 10%

In that case for a watch sold for ksh 126 a loss 10% is made, that is( 100 - 10)%

Hence, loss amount = (126 X 100)/90 = ksh 140

∴ the buying price is ksh 140

I’m stuck on this please someone help

Answer: $\bold{a_{n+1}=\dfrac{1}{2}a_n}$

Step-by-step explanation:

Term-to-term rule is also called the recursive rule.

The recursive rule for a geometric sequence is: $a_{n+1}=a_n\cdot r$ where

$a_n\ \text{is the previous term}$
r is the common ratio

The common ratio (r) is the second term divided by the first term (which is the same ratio for each term divided by its previous term)

In the given sequence {64, 32, 16, 8, 4}, $r=\dfrac{32}{64}\quad \rightarrow \quad r=\dfrac{1}{2}$

So, the recursive rule is: ${a_{n+1}=a_n\cdot \dfrac{1}{2}$

If the area of a rectangle 16s2t and the length is 8st2, what would the width of the rectangle, given that width is found by div

Dafna1 [17]

Area = Length x Width
Substituting the given values:
16S^2 t = 8St^2 x Width
Manipulating for Width:
Width = 16S^2 t / 8St^2
Rewriting the squared terms in simplified form :
Width = 16 x S x S x t / 8 x S x t x t
Cancelling the like terms
Width = 16 x S / 8 x t
Cancelling the numeric terms :

Width = 2S / t
