For 50 kids, the number of parents that would be required would be 15 parents.

<h3>How many parents for 50 kids? </h3>

The first step is to determine the number of parents needed for 1 kid:

1 kid required 3/10 parents

Now, multiply that ratio by 50: 3/10 x 50 = 15 parents

Write the line equation for the line passing through the points (8, 3) and (12, -1).
Aneli [31]

Answer:

Line equation is y=-x+11

The product of the slope and the y-intercept is -11

Step-by-step explanation:

Use the slope formula to find the slope of the equation.

yvalue2 minus yvalue1 /xvalue 2 minus xvalue1

-1-3/12-8=-1

The slope is -1.

Now, use the slope-intercept formula to find the y-intercept

y-3=-1(x-8)

y-3=-x+8

y=11

The equation is y=-x+11

The product of the slope and the y-intercept is -1(11)=-11

Hope this helps.

a quantity with an initial value of 5900 decays exponentially at a rate of 0.85% every 7 years. what is the value of the quantit
laila [671]

The value of the quantity after 99 months is 5228.58.

Given that,  an initial value = 5900, rate of decay = 0.85% and time period = 7 years.

<h3>What is the exponential decay?</h3>

The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.

The exponential decay formula formula is Amount=Initial\ value(1-\frac{r}{100} )^{\frac{t}{n} }

Here, the value =5900(1-\frac{0.85}{100} )^{\frac{99}{7} }

= 5900×(0.9915)^{14.14}

= 5900×0.8862

= 5228.58

Therefore, the value of the quantity after 99 months is 5228.58.
