Answer:

C. 22/7

Step-by-step explanation:

You may be aware that 22/7 is a value used to approximate π almost as often as is 3.14.

In case you actually want to carry out the calculations, you have ...

C = πd

π = C/d

π ≈ (60 3/50)/(19 11/100) = (3003/50)/(1911/100) = 6006/1911 = 22/7

π ≈ 77/(24 1/2) = 77/(49/2) = 22/7

π ≈ (86 9/10)/(27 13/20) = (869/10)/(553/20) = 1738/553 = 22/7

π ≈ 99/(31 1/2) = 99/(63/2) = 22/7

Which expression is equivalent to this expression? x(2x+3) Question 1 options: 2x2+3 2x2+3x 2x2−3x 3x + 3

sleet_krkn [62]

Answer:

$2x^2+3x$ is the expression which is equivalent to $x\left(2x+3\right)$ .

In other words:

$x\left(2x+3\right)=2x^2+3x$

Step-by-step explanation:

Given the expression

$x\left(2x+3\right)$

solving

$x\left(2x+3\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$a=x,\:b=2x,\:c=3$

$=x\cdot \:2x+x\cdot \:3$

$=2xx+3x$

$=2x^2+3x$ ∴ $2xx=2x^2$

Thus,

$x\left(2x+3\right)=2x^2+3x$

Therefore, $2x^2+3x$ is the expression which is equivalent to $x\left(2x+3\right)$ .

The circumference of Circle F is 72 cm. What is the length of Arc DE (the minor arc)?

Tom [10]

You need to first set up the equation:

It would look like 90 divided by 360 multiplied by the given circumference which is 72 cm.

So 90 / 360 x 72

Simply the fraction above, it will give us:

¼ x 72

So the answer would be 18 cm that is the length of DE (minor arc)

storchak [24]

150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people
