Answer with explanation:

\bar{AB}\cong\bar{CD}

                                     ---------------------[Given]

\bar{AB}=\bar{CD}

                                   -----------------[By definition of congruent segments]---(2)

Also, AB= AE + EB

CD= CF +FD

Substituting the value of , AB and CD in equation (2),which reduces to

A E + E B=CF +FD

Also, \bar{CF}=\bar{EB}

CF=E B--------[By definition of congruent segments]

A E + E B=FD +E B→→[Substitution Property]

Subtracting EB , from both sides

AE +EB - EB = FD + EB - EB

Which gives, A E = F D→→→→[Subtraction Property of Equality]

\bar{AE}\cong\bar{FD}

→→→The Missing reason in the proof is :

Option(D.): Subtraction Property of Equality

After the increase the price of a rail season ticket from brighton to london was 2828.80 work out the price before this increase
Scrat [10]

Answer:

2720

Step-by-step explanation:

Given that,

Price of the ticket = 2828.80

To find,

The price before the increase = ?

<u>Procedure</u>:

Let the price before the increase be x

so,

x(100% + 4%) = 2828.80

⇒ 1.04x = 2828.80

⇒ x = 2828.80 ÷ 1.04

∵ x = 2720

Thus, the price before the increase was 2720.

Maria divides 2015 by 1. Then she divides 2015 by 2 and then in order by 3, 4 etc. up to and including 1000. For each division s
9966 [12]

The biggest remainder obtained by dividing 2015 by either 1, 2, 3,

4,...,1000 is the option;

(C) 671

<h3>How can the biggest remainder be found?</h3>

The given number Maria divides is 2015

The divisors = 1, 2, 3, 4,..., 1000

Required:

The biggest remainder Maria noted down.

Solution:

From remainder theorem, we have;

p(x) = (x - a) × q·(x) + r(x)

Where;

r(x) = The remainder

q(x) = The quotient

(x - a) = The devisor

Which gives;

\dfrac{r(x) }{(x - a)}  = \dfrac{p(x) }{(x - a)} -\dfrac{(x - a) \times q(x) }{(x - a)} = \mathbf{ \dfrac{p(x) }{(x - a)} -q(x)}

Therefore;

r(x) = \mathbf{\left(\dfrac{p(x) }{(x - a)} -q(x) \right) \times (x - a)}

The remainder is largest when both  \left(\dfrac{p(x) }{(x - a)} -q(x) \right) and (x - a) are large

\left(\dfrac{p(x) }{(x - a)} -q(x) \right) is largest when the quotient changes to the next lower

digit and the divisor is not a factor.

By using MS Excel, we have, at 672, the remainder is found as follows;

r(x) = \left(\dfrac{2015}{672} -2\right) \times (672) = 671

At 672,  \left(\dfrac{p(x) }{(x - a)} -q(x) \right) ≈ 0.999, which when multiplied by 672, gives

the biggest remainder of 671, which is the biggest remainder.

  • The biggest remainder obtained by dividing 2015 by either 1, 2, 3, 4,...,1000 is <u>(C) 671</u>
