In order to overtake Susie in the election, Calvin must obtain at least 59% of the votes still cast.

Let's assume that there are a total of 100 votes in the election. If Susie receives 53% of the first 80 votes, she gets:

0.53 x 80

= 42.4 votes

And if Calvin receives 47% of the first 80 votes, he gets:

0.47 x 80

= 37.6 votes

So, Susie is currently ahead by:

42.4 - 37.6

= 4.8 votes

Now, let's assume there are N remaining votes. We want to know what percentage of the remaining votes Calvin needs to win, so we can set up an equation:

0.47 × (80 + N)

= 0.53 × (80 + N) - 4.8

Simplifying this equation, we get:

0.06 x (80 + N)

= 4.8

Dividing both sides by 0.06, we get:

80 + N = 80

N = 80

So, there are 80 remaining votes. To find the percentage of these votes that Calvin needs to win, we can set up another equation:

0.47 x (80 + 80) + x/100 x 80

= 0.53 x (80 + 80)

Simplifying this equation, we get:

37.6 + 0.8x = 84.8

Subtracting 37.6 from both sides, we get:

0.8x = 47.2

Dividing both sides by 0.8, we get:

x = 59

So, Calvin needs to win at least 59% of the remaining votes to catch up to Susie in the election.

Step-by-step explanation:

Answer:

[tex]y = \tan(x + \frac{x^2}{2})[/tex]

Step-by-step explanation:

Poorly formatted question; The complete question requires that we prove that [tex]y=\tan(x+\frac{x\²}{2})[/tex]

When

[tex]\frac{dy}{dx} =1+xy\²+x+y\²[/tex] and [tex]y(0)=0[/tex]  

We have:

[tex]\frac{dy}{dx} =1+xy\²+x+y\²[/tex]

Rewrite as:

[tex]\frac{dy}{dx} =1+x+xy\²+y\²[/tex]

Factorize

[tex]\frac{dy}{dx} = (1+x)+y\²(x+1)[/tex]

Rewrite as:

[tex]\frac{dy}{dx} = (1+x)+y\²(1+x)[/tex]

Factor out 1 + x

[tex]\frac{dy}{dx} = (1+y\²)(1+x)[/tex]

Multiply both sides by [tex]\frac{dx}{1 + y^2}[/tex]

[tex]\frac{dy}{1+y\²} = (1+x)dx[/tex]

Integrate both sides

[tex]\int \frac{dy}{1+y\²} = \int (1+x)dx[/tex]

Rewrite as:

[tex]\int \frac{1}{1+y\²} dy = \int (1+x)dx[/tex]

Integrate the left-hand side

[tex]\int \frac{1}{1+y\²} dy = \tan^{-1}y[/tex]

Integrate the right-hand side

[tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex]

[tex]y(0)=0[/tex] implies that: [tex](x,y) = (0,0)[/tex]

So:

[tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex] becomes

[tex]\tan^{-1}(0) = 0 + \frac{0^2}{2} + c[/tex]

This gives:

[tex]0 = 0 +0 + c[/tex]

[tex]0 =c[/tex]

[tex]c = 0[/tex]

The equation [tex]\tan^{-1}y = x + \frac{x^2}{2} + c[/tex] becomes

[tex]\tan^{-1}y = x + \frac{x^2}{2} + 0[/tex]

[tex]\tan^{-1}y = x + \frac{x^2}{2}[/tex]

Take tan of both sides

[tex]y = \tan(x + \frac{x^2}{2})[/tex] --- Proved

Answer:

8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.

A total of 16 questions.

Step-by-step explanation:

The number of multiple-choice questions and the number of short answer type questions are the same.

Let it be equal to [tex]x[/tex]

→Average time it takes to attempt multiple choice question = 2 minutes

→Total time it takes to attempt multiple choice question = [tex]2 * x[/tex] minutes

→Average time it takes to attempt short answer type question = 3.5 minutes

→Total Time it takes to attempt short answer type question = [tex]3.5 * x[/tex] minutes

Total time for the test should be less than 45 minutes.

Now finally, we can make an equation out of the information listed above:

[tex]2x +3.5x <45[/tex]

[tex]\\ 5.5x <45[/tex]

[tex]x < 8.18[/tex]

Hence the value of [tex]x = 8[/tex]

Answer:

x int (18/5,0)

y int (0.-2)

Step-by-step explanation:

by substitution

Answer:

x-intercept: (3.6, 0)

y-intercept: (0, -2)

Step-by-step explanation:

The x and y intercepts of a line can be found by substituting y= 0 and x= 0 into the equation of the line respectively. The y-intercept is the point at which the line cuts through the y-axis, while the x-intercept is the point at which the line cuts through the x-axis.

-5x +9y= -18

When x= 0,

-5(0) +9y= -18

9y= -18

Dividing both sides by 9:

y= -18 ÷9

y= -2

Thus, the y-intercept occurs at (0, -2).

When y= 0,

-5x +9(0)= -18

-5x= -18

Divide both sides by -5:

x= -18 ÷(-5)

x= 3.6

Thus, the x-intercept occurs at (3.6, 0).

Answer:

Then 1/2 or  30 minutes is the required time for Tom to cover the exact distance that Linda one hour before.

Two hours after Tom began Tom would cover 12 miles and three hours after Linda started Linda would be 6 miles far away from the starting point

Step-by-step explanation:

Linda walks in a straight line at 2 miles/hour

then after t ( hours time) she is    2 (m/h) * t   = d (L)

for Tom running at 6 m/h starting one hour later to cover the same distance d(L)

d(L)  =  6 m/h * ( t - 1 )    then:

2 (m/h) * t   =   6 m/h * ( t - 1 )

2*t  =  6*t - 6

4*t = 6

t = 6/4

t =  1,5 h

Checking that result.

we see that in 1,5 hours Linda has covered  2* 1,5  = 3 miles

and  in 0.5 hours  Tom covered the same distance  0,5 * 6 = 3 miles

NOTE: Remember that tom started one hour later.

Then 1/2 or  30 minutes is the required time for Tom to cover the exact distance that Linda one hour before.

b)  In this case

d(T) = 6* ( t - 1 )       must be equal  to  twice of the Linda distance

d(L)  = 2 * 2 * t

6*t - 6  =  4*t

2*t  =  6

t  = 3

To check it

in 3 hours   Linda had covered  3 * 2  =  6 miles

in 2 hours   Tom had covered   2 * 6  =  12 miles

Answer:

h(x) = 3(x - 9)² - 2

Step-by-step explanation:

Rules for translation of a function are as follows:

f(x) + a = vertical translation of f(x) upwards by a units

f(x) - a = vertical translation of f(x) downwards by a units

f(x + a) = horizontal translation of f(x) leftwards by a units

f(x - a) = horizontal translation of f(x) rightwards by a units

So, using the above the rules:

h(x) = f(x - 4) - 1

h(x) = (3((x - 4) - 5)² - 1) - 1

h(x) = 3(x - 9)² - 2

Answer:

Liliana tiene 10 años.

Step-by-step explanation:

Definamos las variables:

E = edad de Ericka

L = edad de Liliana.

Primero sabemos que la edad de Ericka es el triple de la edad de Liliana, entonces:

E = 3*L

Tambien sabemos que hace 9 años la suma de sus edades era 22

Hace nueve años la edad de Ericka era E - 9

Y hace nueve años la edad de Liliana era L - 9

Entonces tenemos:

(E - 9) + (L - 9) = 22

Así, tenemos un sistema de dos ecuaciones:

E = 3*L

(E - 9) + (L - 9) = 22

Queremos conocer la edad actual de Liliana.

Para ello tenemos que despejar E en una de las ecuaciones.

Podemos ver que en la primer ecaución E ya está aislada, entonces nos saltamos ese paso.

Ahora, reemplazamos E en la otra ecuación:

(E - 9) + (L - 9) = 22

(3*L - 9) + (L - 9) = 22

Ahora podemos resolver esto para L

3*L - 9 + L - 9 = 22

4*L - 18 = 22

4*L = 22 + 18

4*L = 40

L = 40/4 = 10

L = 10

Liliana tiene 10 años.

Answer:

216 cubic centimeters

Step-by-step explanation:

The details of the word problem are as follows;

The length of the edges of a cube, s = 6 cm

The volume of the cuboid = The volume of the cube

The length of a side of the cuboid = 4 cm

The length of the other side of the cuboid - 6 cm

The volume of the cube, V = 6 cm × 6 cm × 6 cm = 216 cm³

The volume of the cuboid, [tex]V_c[/tex] = 4 cm × 6 cm × T

Where 'T' represent the length of the third side

Therefore, 'T' = 216 cm³/(4 cm × 6 cm) = 9 cm

The length of the third side, T = 9 cm

The volume of the cuboid = The volume of the cube = 216 cm³
