Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Two measures of arc are given by

PR = (x+5), and SQ = (x-5).

By intersecting chords theorem, the measure of angle is half of the sum of the measures of arcs.

$\angle A=\frac{x+5+x-5}{2}\\\\\angle A=\frac{2x}{2}\\\\\angle A=x$

And ∠A and ∠B are linear pair.

so, it becomes,

$\angle A+\angle B=180^\circ\\\\x+37^\circ=180^\circ\\\\x=180^\circ-37^\circ\\\\x=143^\circ$

Hence, Option 'C' is correct.

So I think I understand this so,
a) yes there is a correlation because the more workers they have the greater number of products they can produce
b) y=120x +80
c) The slope (80) indicates that it increases by 80 points or 80 products and the y intercept (120) indicates that at 0 employees there were 120 products being made.

The government, through a subsidy program, distributes $10000000. If each person or agency spends 55% of what is received,

Lady bird [3.3K]

Answer:

$ 12,222,222.22

Step-by-step explanation:

Let P be the initial amount distributed,

Since, the spending in first instance = 55% of P

= 0.55(P)

In second instance = 55% of (0.55(P)) = 0.55² P

In third instance = 55% of (0.55² P) = 0.55³ P,

............................., so on.....

Thus, total increase in spending = 0.55P + 0.55² P + 0.55³P.....

We know that,

0.55P, 0.55²P, 0.55³P,..............

Is a GP with infinite number of terms,

Having first term, a = 0.55P,

Common ratio, r = 0.55,

Hence, the sum of the above series,

$S = \frac{a}{1-r}$

$=\frac{0.55P}{1-0.55}$

$=\frac{0.55P}{0.45}$

$=\frac{11P}{9}$

Here, P = $ 10000000,

Therefore, total amount increase = $\frac{11\times 10000000}{9}$

$=\frac{110000000}{9}$

= $ 12,222,222.22
