Nastasia [14]

3.2m casts 1.54m shadow.

3.2÷1.54= 160/77 (2.077922077922...)

50.75 × 160/77= 105.454545...

In the figure below, segment AC is congruent to segment AB.

sattari [20]

Answer:

Option B is correct.

Angle DAC is congruent to angle DAB

Step-by-step explanation:

Given: Segment AC is congruent to segment AB.

In ΔABD and ΔACD

$AB \cong AC$ [Given]

[Congruent sides have the same length]

AB = AC [Side]

AD = AD [Common side]

$\angle DAC =\angle DAB$ [Angle]

Side Angle Side(SAS) Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Then by SAS,

$\triangle ABD \cong \triangle ACD$

By CPCT [Corresponding Parts of congruent Triangles are congruent]

then;

$\angle ABD \cong \angle ACD$

therefore, only statement which is used to prove that angle ABD is congruent to angle ACD is: Angle DAC is congruent to DAB

The organizers of a fair projected a 25 percent increase in attendance this year over that of last year, but attendance this yea

Gnom [1K]

Answer: 64 %

Step-by-step explanation:

Assume attendance last year to be equal to "x"

- An increase in percentage sees us add the percentage amount to 100.

- A decrease in percentage sees us subtract the percentage amount from 100.

Projected attendance = ((100+25)/100) * x = 1.25x

Actual attendance = ((100-20)/100) * x = 0.80x

Hence ratio of a actual to projected attendance = 0.80x/1.25x = 0.64

Convert into percentage = 0.64 * 100 = 64 %

How can you subtract fractions with unlike denominators?

Rama09 [41]

Answer:

No, You can't. You have to make their denominators equal!

$-\frac{7}{10}$

Step-by-step explanation:

So first, you make their denominators equal!

$\frac{1*2}{5*2} =\frac{2}{10}=\frac{1}{5}$

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified

So, we input it!

$\frac{2}{10} -\frac{9}{10} = -\frac{7}{10}$

There you go!

Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)

Hope this helps!

See Ya!

P.S. Stay Safe!

A person sold 100 shares of a stock at a loss of 40%. If the selling price for the 100 shares was $3,000, which of the following

Kisachek [45]

A person sold 100 shares of a stock at a loss of 40%.

selling price for the 100 shares was $3,000

Let the stock was bought at $x then we can write

$x-\frac{40x}{100}=3000\\ \\ \frac{100x-40x}{100}=3000\\ \\ \ \frac{60x}{100}=3000\\ \\ \ 60x= 3000*100\\ \\ x=\frac{3000*100}{60} \\ \\ \ x=5*100=5000\\$

Hence Amount paid for the Stock was $5000
