A car dealership needs to transport 58 cars to a new lot. If the transport truck can haul 6 cars at a time, how many trips will the transport truck need to make?

Answer:

YES

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Because -5x and 5x both have the same things in it (a full base number and variable), they are like terms. It doesn't matter that one is a negative and the other is not. It's just matters that everything else is the same.

I hope this helps!

Answer:

esta Frase es correcta se a los amigos de mis Padres true false

Let the number of men and the number of women in the beginning be x and y

Now,[tex]\sf \frac{x} {y} =\frac{5}{2} \\\\\sf

=2x=5y \\\\\sf

=x=\frac{5y}{2}[/tex]

Now, In 2nd case,

No. Of men=x-63 and no. Of women =y-12

Now,the ratio becomes[tex] \frac{x-63}{y-12}=\frac{7}{4} \\\\\sf

=4(x-63)=7(y-12) \\\\\sf

=4x-252=7y-84 \\\\\sf

Putting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf

10y-252=7y-84 \\\\\sf

=10y-7y=252-84 \\\\\sf

=3y=168 \\\\\sf

=y=56 \\\\\sf

=\boxed{Y=56}

[/tex]

Now,we have, 2x=5y

Putting the value of Y=56 in 2x=5y,we get,

[tex]\sf 2x=5\:x\:56 \\\\\sf

x=\frac{5\:x\:56}{2} \\\\\sf

x=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf

=x=5\: x\: 28 \\\\\sf

x=140 \\\\\sf

\boxed{x=140}

[/tex]

Hence, the number of men was 140 and the no. of women was 56

15 and 9 are like terms because they can be simplified together. 15+9, 15-9, 15*9 can all be simplified further.

-10xy and 9x are not like terms because they cannot be simplified without the variables first being defined.

Answer:

  P(x) = (2x)(x)(x-4)(x+2)

Step-by-step explanation:

Once the common factor of 2x^2 is factored out, you have ...

  P(x) = 2x^2(x^2 -2x -8)

To factor the quadratic, you look for factors of -8 that have a sum of -2.

  -8 = (1)(-8) = 2(-4)

These last factors have that sum, so we can write P(x) as ...

  P(x) = (2x)(x)(x +2)(x -4)

Answer:

  3.75 hours

Step-by-step explanation:

Travel time can be found using the relation ...

  time = distance/speed

  time = (2475 mi)/(660 mi/h) = 3.75 h

It will take 3 3/4 hours to travel that distance.

Answer:

-12x - 14y

Step-by-step explanation:

First I would move them side by side so I can see it better so:

-7x - 5x - 8y - 6y

now combine the x values together and the y values together:

-12x - 14y

Answer:

A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint

Step-by-step explanation:

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality

Complete Question

The SAT are scored so as to yield a mean of 500 and a standard deviation of 100. These scores are close to being normally distributed. An exclusive club wishes to invite those scoring in the top 5% on the College Boards to join. a. Find percentages of scores that is between 480 and 590. b. What score is required to be invited to join the club? c. What score separates the top 60% of the population from the bottom 40%? What do we call this value? (hint: the score that separates the top 20% of the population from the bottom 80% is called the 80th percentile)

Answer:

a

 [tex]P(480 < X  <  590) =  0.3952[/tex]  

b  

  [tex]x =  664.5 [/tex]

c

 [tex]x_1 =  474.67[/tex]

The value is called the [tex]40^{th}[/tex] percentile

Step-by-step explanation:

From the question we are told that

The mean is [tex]\mu = 500[/tex]

The standard deviation is [tex]\sigma = 100[/tex]

Generally the percentage of the score that are between 480 and 590 is mathematically represented as

[tex]P(480 < X < 590) = P(\frac{ 480 - 500}{ 100} < \frac{ X - \mu }{ \sigma } < \frac{ 590 - 500}{ 100} )[/tex]

Here [tex]\frac{ X -\mu}{\sigma } = Z[/tex]

=> [tex]P(480 < X < 590) = P(\frac{ 480 - 500}{ 100} < Z < \frac{ 590 - 500}{ 100} )[/tex]

=> [tex]P(480 < X < 590) = P(-0.2< Z < 0.9 )[/tex]

=> [tex]P(480 < X < 590) = P(Z < 0.9 ) - P(Z<-0.2) [/tex]

From the z table (reference calculator dot net )

[tex] P(Z < 0.9 )= 0.81594 [/tex]

And

[tex] P(Z < -0.2 )= 0.42074 [/tex]

=> [tex]P(480 < X < 590) = 0.81594 - 0.42074 [/tex]

=> [tex]P(480 < X < 590) = 0.3952[/tex]

Converting to percent

[tex]P(480 < X < 590) = 0.3952 * 100[/tex]

[tex]P(480 < X < 590) = 39.52\% [/tex]

The percentage invited to join the club is the top 5% , this can be mathematically represented as

[tex]P(X > x ) = 0.05[/tex]

Here x is the score that is within the top 5%

=> [tex]P(X > x) = P( \frac{X - \mu }{\sigma } > \frac{ x - 500}{100} )= 0.05[/tex]

Generally the critical value of 0.05 from the normal distribution table is

[tex]Z_{0.05} = 1.645[/tex]

So

[tex]\frac{ x - 500}{100} = 1.645[/tex]

=> [tex]x - 500 = 164.5[/tex]

=> [tex]x = 664.5 [/tex]

Generally the probability of having a score that separates the top 60% of the population from the bottom 40%

[tex]P(X > x_1 ) = 0.60[/tex]

=> [tex]P(X > x_1) = P(\frac{ X - \mu }{\sigma } > \frac{x - 500}{100} ) = 0.60[/tex]

The critical value of 0.60 from the normal distribution table is

[tex]Z_{0.60} = - 0. 2533[/tex]

So

[tex]\frac{x_1 - 500}{100} = -0.2533[/tex]

=> [tex]x_1 = 474.67[/tex]

From the hint given we can see that this value is called the [tex]40^{th}[/tex] percentile

Answer:

False

Step-by-step explanation:

To find the opposite of an integer, we just change its sign. If it is negative, change to positive. If it is positive change to negative. Opposite integers are the pairs of integers that have the same absolute value, or the same distance from zero. The sum of two opposites is always zero.

No, triangle B is a reflection of triangle A.

Step-by-step explanation:

The points of triangle A are reflected across the dotted line. So as a result triangle B is a reflection of triangle A.

Answer:

No

Step-by-step explanation:

Its a reflection because even if you did rotate it it would never be in that orientation.

Answer:

1. |40 – 4x| < 4

2. 9 < x < 11

Step-by-step explanation:

We'll begin by calculating the area of each figure. This can be obtained as follow:

For triangle:

Area = ½ × base × height

Base = 8

Height = 6

Area =?

Area = ½ × 8 × 6

Area = 4 × 6

Area = 24

For Rectangle:

Area = length × breadth

Length = x – 4

Breadth = 4

Area =?

Area = (x – 4) × 4

Area = 4x – 16

Summary:

Area of triangle (Aₜ) = 24

Area of rectangle (Aᵣ) = 4x – 16

1. Writing an absolute value for the inequality.

From the question given above, we were told that the difference between the areas of the figures is less than 4. This can be written as:

Aₜ – Aᵣ < 4

Area of triangle (Aₜ) = 24

Area of rectangle (Aᵣ) = 4x – 16

24 – (4x – 16) < 4

Simplify

24 – (4x – 16) < 4

Clear bracket

24 – 4x + 16 < 4

24 + 16 – 4x < 4

40 – 4x < 4

Thus, we can write the absolute value for the above inequality as:

|40 – 4x| < 4

2. Determination of the solution of the inequality.

This is illustrated below:

|40 – 4x| < 4

Thus the above equation can be written as

– 4 < 40 – 4x < 4

Subtract 40 from both side

– 4 – 40 < 40 – 4x – 40 < 4 –40

– 44 < – 4x < – 36

Divide through by –4

– 44/–4 < x < – 36/–4

11 > x > 9

Note: the inequality sign changed because we divided by a negative number

Thus, 11 > x > 9 becomes 9 < x < 11

Therefore, the solution to the inequality is 9 < x < 11
