Answer:

First option.

Step-by-step explanation:

In this case you need to remember that an angle formed by two intersecting chords is equal to the sum of the intercepted arcs divided by 2. This is:

$Angle\ formed\ by\ two\ intersecting\ chords=\frac{1}{2}(Sum\ of\ intercepted\ arcs)$

You can identify in the figure that the angle ∠1 is an angle formed by two intersecting chords. Therefore, since the intercepted arcs are SP and QR, you can say the following:

$m\angle 1=\frac{1}2}(mSP+mQR)$

You can observe that this matches with the first option.

How old am I if 500 reduced by 3 times my age is 278?

ZanzabumX [31]

Let your age = X

Now you have 500 - 3x = 278

Subtract 500 from each side:

-3x = -222

Divide both sides by -3:

x = -222 / -3

x = 74

You are 74 years old.

A bacteria culture starts with 100 bacteria and doubles in size every half hour.

taurus [48]

Answer:

y=25600

y=100(2)^{2t}

y=252

Step-by-step explanation:

A bacteria culture starts with 100 bacteria and doubles in size every half hour.

$y=100(2)^{2x}$

where x represents the number of hours

(a) t= 4 hours

Plug in 4 for t and find out the number of bacteria y

$y=100(2)^{2 \cdot 4}\\y=25600$

25600 bacteria

$y=100(2)^{2t}$

convert 40 seconds into hour

40 divide by 60 =2/3

$y=100(2)^{2\frac{2}{3} }\\y=100(2)^{\frac{4}{3} }\\\\y=252$

The graph is attached below

What is the solution to the system of equations?

Maslowich

Answer:

B) (10, -20)

Step-by-step explanation:

Plug in the values to y = -5x + 30 to see if they match:

we already know that x = 10 so are equation will always be:

y = -5(10) + 30 = -50 + 30 = -20

our new equation is y = -20

so your answer is B) (10, -20)

because the X-value has to be 10 and Y-value is equal to -20
