Marci has a scale drawing of her new bedroom. On the drawing the length of the bedroom is 2cm. In real life her bedroom is going to be 7 meters in length. What is the scale of the drawing

Answers

Answer 1

Answer:

Scale for drawing is 1:350

Step-by-step explanation:

scale is ratio of size of drawing and size of actual object for which the drawing is made

it is represented as

scale = size of drawing : size of actual object

given

length of model in drawing = 2cm

length of bedroom in reality = 7 meter

since there are two units we meter and cm

we convert both in same unit that is cm for simpler calculation

1 meter = 100 cm

7 meter = 7*100 cm = 700cm

length of bedroom in reality = 7 meter = 700 cm

Thus,

scale for drawing = length of drawing/ actual length of bedroom

scale for drawing = 2 cm : 700cm = 1:350

Scale for drawing is 1:350

The perimeter of each polygon created by the coordinates is 15.2 units

How to find the perimeter of each polygon created by the coordinates?

The coordinates are given as:

A(-2, 3), B(3, 1), C(-2, -1), D(-3, 1)

Calculate the distance between each point using

d = √(x2 - x1)^2+ (y2 - y1)^2

So, we have:

dAB = √(-2 - 3)^2+ (3 - 1)^2 = 5.4

dBC = √(3 + 2)^2+ (1 + 1)^2 = 5.4

dCD = √(-2 + 3)^2+ (-1 - 1)^2 = 2.2

dDA = √(-3 + 2)^2+ (1 - 3)^2 = 2.2

The perimeter is calculated as:

P = 5.4 + 5.4 + 2.2 + 2.2

Evaluate

P = 15.2

Hence, the perimeter of each polygon created by the coordinates is 15.2 units

The possible coordinates of the midpoint are 3 and -3

Step-by-step explanation:

The given information are;

The coordinate of the point A on a (horizontal) number line = 0

The length of AR =

The coordinate of the midpoint of AR are given as follows;

Coordinate of the midpoint = Coordinate of A ± (Length of AR)/2 which gives;

Answer:

AngleAFB

Step-by-step explanation:

We know that vertical angles are angles that opposite each other when two lines intersect. They share a common point or vertex.

In the question, the angle opposite to angle EFD is angle AFB. This is because they share a common vertex.

Since they share a common vertex and are opposite to each other, angle AFB is the angle vertical to angle EFD.

So, the angle vertical to angle EFD is angle AFB.

Answers

Answer:

23.33%

Step-by-step explanation:

The computation of the percentage of days in a month for running out of cash is shown below:

Percentage of running out of Cash is

= (Relevant Occurrence  of an event ÷  Total number of events) × 100%

where,

The Relevant occurrence of an event is 7 (105,94,101,98,94,96,92)

And, the total number of events is 30 i.e. 30 days

So, the percentage is

a door with width 4.20 m has an arc as shown in diagram .Find: a) radius of the arc B) length of the arc to the nearest cm

Answers

Answer:

Ok, we know that the width of the door is 4.20m.

Then, if the arc is at the top of the door, we will have that the diameter of that "half circle" will be equal to the width of the door.

Then the diameter of the arc is 4.20m

And the radius is defined as half of the diameter, so we have:

radius = 4.20m/2 = 2.10m

And we can write this in cm (because the probelm ask for it)

1m = 100cm

then 2.10m = 2.1*100cm = 210cm

Now, we know that the perimeter of a circle is:

P = 2*pi*r

where pi = 3.14

Then the perimeter (or arc) of half a circle will be half of that:

Arc = (2*pi*r)/2 = pi*r

and r = 210cm, pi = 3.14

Arc = 3.14*210cm = 659.4cm

Many states assess the skills of their students in various grades. One program that is available for this purpose is the National Assessment of Educational Progress (NAEP). One of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In a recent year, the national mean score was 289 and the standard deviation was 37. Assume that these scores are approximately Normally distributed, N(289, 37). How high a score is needed to be in the top 25% of students who take this exam (use technology)?

Answers

Answer:

A score of 314 is needed to be in the top 25% of students who take this exam.

Step-by-step explanation:

We are given that one of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In recent years, the national mean score was 289 and the standard deviation was 37.

Let X = scores of the tests provided by the NAEP

The z-score probability distribution for the normal distribution is given by;

                           Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = national mean score = 289

           [tex]\sigma[/tex] = standard deviation = 37

Now, we have to find how high a score is needed to be in the top 25% of students who take this exam, that means;

            P(X > x) = 0.25     {where x is the required score}

            P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-289}{37}[/tex] ) = 0.25

            P(Z > [tex]\frac{x-289}{37}[/tex] ) = 0.25

In the z table, the critial value of z that represents the top 25% of the area is given as 0.6745, that is;

                        [tex]\frac{x-289}{37}=0.6745[/tex]

                        [tex]{x-289}=0.6745\times 37[/tex]

                        x = 289 + 24.96 = 313.96 ≈ 314

Hence, a score of 314 is needed to be in the top 25% of students who take this exam.

Can you find the cube
root of a negative number if so I’d it positive or negative

Answers

Step-by-step explanation:

Yes. The cube root of a negative number will be negative.

For example, (-2)^3 = -8. The cube root of -8 is -2.

Answer:

Yes, it would be negative

Step-by-step explanation:

Yes, the cube root of a negative number can be found without using imaginary numbers to represent it.

The cube of a number is that number multiplied by itself 3 times so:

a^3 = a*a*a

if "a" is negative then the cube of "a" will be negative. Hence the cube root of a negative number will be negative.

What are the x-intercepts of the graph of the function f(x) = x^2 + 4x – 12?
(-6,0). (2.0)
(2. -16). (0, -12)
(-6.0), (2, -16), (2, 0)
(0.-12).(-6, 0), (2, 0)​

Answers

Answer:

(- 6, 0 ) , (2, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0, that is

x² + 4x - 12 = 0 ← in standard form

(x + 6)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 2 = 0 ⇒ x = 2

Thus the x- intercepts are (- 6, 0 ), (2, 0 )
