2 of a dozen eggs are cracked. What percent of the carton is NOT cracked using the percent proportion

levacccp [35]

If 2 of 12 eggs are cracked, then 10 are not cracked.

10/12=5/6=about 0.83

0.83 of total eggs not cracked is also equivalent to 83 percent as asked in the problem :)

To describe a specific arith-

Bezzdna [24]

Answer:

$f(x) = 7x + 30$

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

$f(0) = 30$

$f(n + 1) = f(n) + 7$

When we substitute n=0, we get:

$f(0 + 1) = f(0) + 7$

$f(1) = 30 + 7$

$f(1) = 37$

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

$f(x) = mx + b$

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

$f(x) = 7x + 30$

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

$m = \frac{37 - 30}{1 - 0} = 7$

Q10<br> Please help me solve this….

kondor19780726 [428]

Answer:

C. 0.23°

Step-by-step explanation:

We are given

$r=\frac{1}{32}v^{2}sin(2\theta)$

Re-arranging this equation (multiply by 32 on both sides and divide by $v^{2}$ on both sides gives us:

$\frac{32r}{v^{2}}=sin(2\theta)$ or

$sin(2\theta)=\frac{32r}{v^{2}}$

Substituting for, r and v we get

$sin(2\theta)=\frac{(32)5000}{4500^{2}}=0.00792\\\\\theta=sin^{-1}(0.0079)=0.4527\\\\\theta=\frac{{0.4527}}{2}=0.2263\approx0.23$
