The rectangular floor of a classroom is 38 feet in length and 30 feet in width. A scale drawing of the floor has a length of 19 inches. What is the perimeter, in inches, of the floor in the scale drawing?

Step-by-step explanation:

Answer: 40/11 hours

Step-by-step explanation:

Since y represents the amount of time the car goes at 35 miles per hour, and it is given that the car spends no time at 35 miles per hour, y = 0.

We can plug y into the equation given to find x, which would be the time travelled at 55 miles per hour, or the total time in this case.

55x + 35*0 = 200

55x = 200

x = 200/55

x = 40/11 hours

Answer:  

< means y is smaller than 3, it's not equal, so it's open dots.

(number line see the attach image.)

Answer:

2.5 is greater than 2.

They are not equal

2.5 is in between 2 and 3

Since 3 is greater than 2, and 2.5 is in between them, 2.5 is greater than 2.

Answer:

So a line perpendicular to this equation would be any line with a slope of -3/4 (the negative reciprocal of the slope)

Step-by-step explanation:

First convert the original equation into y = form to find the slope.

Subtract 4x on both sides leaving -3y = -27 - 4x

This leaves y = (-27 - 4x)/(-3)

You can divide both -27 and -4x by -3 individually to get 9 and 4/3 respectively

This makes your equation y = 9 + (4/3)x

Whenever an equation is in y = mx + b form, the 'm' represents the slope. In this case the slope is 4/3.

Answer:

i. 7:6

ii. 7:13

iii. 6:13

Step-by-step explanation:

boys to girls = 140:120 so we can simplify by 20 to get 7:6

boys to total = 140:(120+140) = 140:260 we can simplify again to get 7:13.

girls to total = 120:(120+140) = 120:260 we can also simplify to get 6:13

Answer:

n = -6

Step-by-step explanation:

2 ( n + 5 ) = -2

First, solve the brackets.

2n + 10 = -2

Now take 10 to the right side.

2n + 10 -10 = -2 - 10

2n = -12

Then divide both sides by 2.

[tex]\frac{2n}{2} =\frac{-12}{2}[/tex]

And now you'll the value of n.

n = ( -6 )

Answer:

x < 3

Step-by-step explanation:

Step 1: Add 20 to both sides.

Step 2: Divide both sides by 2.

Answer:

97

Step-by-step explanation:

(a - 48) + a = a + 49

2a - 48 = a + 49

a = 97

We can do this because the angles of a triangle all add up to 180 and 2 angles of a line add up to 180.

Answer:

A) [tex]\frac{1}{4}[/tex]

B)[tex]\frac{2}{4}[/tex]

C)[tex]\frac{2}{4}[/tex]

Step-by-step explanation

sample space (S) = {1,2,3,4}

n(S) = 4

multiples of three (a) = {3}

n(a) = 1

probability of a = [tex]\frac{n(a)}{n(S)}[/tex]

                         = [tex]\frac{1}{3}[/tex]

multiples of two(b) = {2,4}

n(b) = 2

probability of b = [tex]\frac{n(b)}{n(S)}[/tex]

                         = [tex]\frac{2}{4}[/tex]

factors of three(c) = {1,3}

n(c) = 2

probability of c = [tex]\frac{n(c)}{n(S)}[/tex]

                         = [tex]\frac{2}{4}[/tex]

For a particular data generation process, a probability distribution represents the predicted outcomes of various values. The mean of the probability distribution is 3.

For a particular data generation process, a probability distribution represents the predicted outcomes of various values. The mean, standard deviation, skewness, and kurtosis are all features of probability distributions, which are characterized by the mean, standard deviation, skewness, and kurtosis.

The mean of the probability distribution is determined by the given formula,

[tex]\mu = \sum (x\times P(x))[/tex]

Now, substituting the value to know the probability distribution, we will get,

[tex]\mu = (1 \times 0.1)+(2 \times 0.2)+(3 \times 0.4)+(4 \times 0.2)+(5 \times 0.1)\\\\\mu = 0.1+0.4+1.2+0.8+0.5 = 3[/tex]

Hence, the mean of the probability distribution is 3.

The time taken for the golf ball to reach the ground is 1 s.

The path of motion of the golf ball can be described as parabolic because it is projectile.

When the golf ball reaches the ground, the final velocity will be zero.

Velocity of the golf ball is change in height with time.

v = dh/dt

h(t) = -16t² + 32t  + 128

dh/dt = -32t + 32

0 = -32t + 32

32t = 32

t = 1 s

Thus, the time taken for the golf ball to reach the ground is 1 s.

pugs;

pros= Pugs are small in size and thus, making them suitable for small-sized rooms or apartments. Pugs have a friendly and lapdog temperament, get along well with most people and pets. Pugs are low to medium-shed breeds, which implies you are less likely going to be troubled with shedding.

cons= Pugs are prone to various throats, ears, eyes, folds, facial infections, and breathing troubles; hence they will require regular health check-ups. Pug dogs are not highly trainable – it will be difficult to train a pug to do not-so-easy activities even if you hire a professional.

! Can take simple commands without hiring a professional trainer/ train on your own
Cons of  a Pug

! Gains weight easily and lack of daily exercises like a walk or run can easily have them gain weight and affect their health.
! Pug dogs are not highly trainable ~ can do simple tricks like:
sit, stand, run, fetch but not complicated ones
! Health risks ~ Pugs are prone to throat, ears, eyes, facial infections, and breathing troubles :; hence they will require regular health check-ups.

Pros of Poodle
! They don’t shed. Poodles have long hair, instead of fur so they do not shed.
! super easy to train compared to pugs and easily learn hard tricks and so.
! They're good with children or other dogs
! They make great service dogs or therapy dogs
Cons of Poodle
! Their hair requires some serious maintenance
! They can be emotionally sensitive
! IMPORTANT - They require a lot of mental stimulation

These pups have trained to live a luxurious lifestyle they’re rarely content to live as lap dogs. They will use their intelligence for less desired behaviors like digging, chewing, or excessive barking. If your lifestyle doesn’t allow you to provide ample mental stimulation for your dog, it might be worth considering another breed.

Only option d is the correct answer as x = 3 is a solution to the equation.

To solve this problem, we have to substitute the value of x into the equation and see if it is equal to zero.

a)

[tex]3x+7 = x - 8[/tex]

when x = -6

substitute the value of x

[tex]3x+ 7 = x - 8\\x = -6\\3x-x = -8-7\\2x = -15\\2(-6) = -15\\-12 \neq -15[/tex]

equation (a) is wrong.

b)

[tex]-2x-8=-4x-1\\x = 3[/tex]

collect like terms and substitute for x

[tex]-2x-8=-4x-1\\x = 3\\-2x+4x= -1+8\\2x = 7\\2(3) = 7\\6\neq 7[/tex]

equation(b) is wrong

c)

[tex]-5x+7 = 2x - 14\\x = -8\\[/tex]

collect like terms and substitute for x

[tex]-5x+7 = 2x - 14\\x = -8\\7+ 14 = 2x + 5x\\21 = 7x\\21 = 7(-8)\\21 \neq -42[/tex]

d)

[tex]-(x-1)=4x-5-3x\\x = 3\\-(x-1) = 4x -5 -3x\\-x+1 = x- 5\\2x = 6\\2(3) = 6\\6 = 6\\[/tex]

From the above calculation, only option d is the correct answer as x = 3 is a solution to the equation.
