During the election for class president, 40% of the students voted for Gerardo, 35% of the students voted for Leandro, and 25% o
mrs_skeptik [129]

Answer:  30 students more voted for Gerardo than for Juju.

Explanation:

<u>so 'x' represent the total number of students</u>

<u />

<u>0.40x of the students voted for Gerardo</u>

<u />

<u>0.35x of the students voted for Leandro</u>

<u />

<u>0.25x of the students voted for Juju</u>

<u />

<u>70 students voted for Leandro:</u>

<u />

<u>0.35x = 70 </u>

<u />

<u>by solving we find:</u>

<u />

<u>x = 200 students</u>

<u />

<u>0.40x - 0.25x = (0.40 - 0.25)x = 0.15x = 0.15*200 = 30</u>

Identify the equation in slope-intercept form for the line containing the point (−3,5) and parallel to y=−2/3x+53.
Alexeev081 [22]

Answer:

y=−2/3x+3

Step-by-step explanation:

I graphed the point and the equation given below. I used the same slope in the new equation as the original equation. The y-intercept is 3 because the line goes through (0,3).

How much would $500 invested at 3% interest compounded continuously be
77julia77 [94]

Answer:

d

Step-by-step explanation:

598.60

You are given the equation 

A(t) = P*e^(rt) 

Where P = Principal 

r = interest rate 

t = time 

e is a mathematical constant equivalent to approx 2.71828 

You're told the initial Principal is $500, the interest rate is 3%, over 6 years. So you have everything that you need to solve the problem, just plug in the values and solve for A(6) 

A(t) = P*e^(rt) 

A(6) = 500 * e^(0.03 * 6) 

A(6) = 500 * e^(0.18) 

A(6) = 500 * 2.71828^(0.18) 

A(6) = 500 * 1.19721 

A(6) = 598.60861 

So $500 invested 6 years ago at 3% would be worth $598.61 today.

Assume that y varies inversely<br> with x. If y = -6 when x = -2, find<br> y when x = 5.
77julia77 [94]

Answer:

y = 2.4

Step-by-step explanation:

If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"

Hence,

y~1/x

y=k/x

When y =-6 and x =-2, we insert these values to find the value of the constant "k"

-6 = k/-2

k = 12.

Using this value of k to determine value of y when x =5 becomes:

y = 12/5

y = 2.4
