Step2247 [10]3 years ago
4 0

Answer:

No

Step-by-step explanation:

n₁=4

n₂=9

n₃=16

We can see that all three numbers are perfect squares of one higher than the figure number

So, n₁₅=(15+1)²=16₂=256

256≠225

A local deli sells 4-inch sub sandwiches for $2.95. It has decided to sell a “family sub” that is 50 inches long. How much shoul
lilavasa [31]
You take 50/4 which equals 12.5

so now you say “well one sub is 2.95”
take that and multiply it by 12

12 x 2.95 = 35.4

then you take 2.95 and divide it by 2 that is 1.48

so now you take 35.4 + 1.48

the cost should be 36.88

In the circle, m arc BC = 72°. The diagram is not drawn to scale. <br><br>What is m angle BCP
QveST [7]

Answer:

Measure of ∠BCP is 36°

Step-by-step explanation:

Given the circle in which measure of arc BC is 72°

we have to find the measure of angle BCP.

m∠BOC=∠2=72°

By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.

∴ ∠2=2∠1 ⇒ 72=2∠1

⇒    ∠1=36°

By alternate segment theorem which states that

The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.

⇒ ∠3=∠1=36°

Hence, measure of ∠BCP is 36°

Option D is correct

What is the simplified form of 2/x^2-x - 1/x?
Pachacha [2.7K]

Answer:  \bold{(C)\ \dfrac{3 - x}{x(x-1)}}

<u>Step-by-step explanation:</u>

   \dfrac{2}{x^2-x}-\dfrac{1}{x}

=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}

=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}\bigg(\dfrac{x-1}{x-1}\bigg)

=\dfrac{2}{x(x-1)}+\dfrac{-x+1}{x(x-1)}

=\dfrac{2-x+1}{x(x-1)}

=\dfrac{3-x}{x(x-1)}
