The students at Suzanne school are also going to paint a smaller mural inside the building. A scale drawing of the mural is shown on the grid.

Answers

Answer:

The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53

Step-by-step explanation:

The first step will be to find the diagonal of the rea life mural.

We can use Pythagoras' Theorem to do this.

Diagonal = \sqrt{15^2 +45^2 }

15

2

+45

2

=47.43 feet.

Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.

This will be 47.43 / 6.3 units = 7.53.

The scale factor is 7.53

To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.

This will be

Length = 15/ 7.53 = 1.992

Breadth = 45/7.53 = 5.976Length = 15/ 7.53 = 1.992

Breadth = 45/7.53 = 5.976

Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53

what is the area of the figure below

Answers

Answer:

47 units.

Step-by-step explanation:

You can split the shape into smaller pieces to make it easier to digest.

4*8 is 32 which is the top rectangle.

9-4=5 since you are trying to figure out the second rectangle, not the whole side length.

5*3=15

15+32=47

The area of the figure is 47 square units.

What is a rectangle?

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

From the given figure,

We see that,

Two rectangles can be considered.

Now,

One rectangle:

Length = 8

Width = 4

Area = 8 x 4 = 32

Another rectangle:

Length = 5

Width = 3

Area = 5 x 3 = 15

Now,

The area of the figure,

= 32 + 15

= 47

Thus,

The area of the figure is 47 square units.

Seetha, the receptionist of Mind Zone – a mind game center, recorded the number of visitors per day in her logbook and calculated the average per week. While doing the monthly updates she noticed that the data on a particular day is missing as water spilled over it.

What would be the missing value?

Answers

Since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7,  less the total of the non-missing values.

How is a missing value calculated from an average number?

If a number is missing from an average number, we can find the missing number by following these steps:

Add the non-missing numbers.Multiply the mean or average by the total number of variables (e.g. number of days in a week).Subtract the value of the non-missing numbers from the sum in (2) above.

Thus, since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7,  less the total of the non-missing values.

A line passes through the points (4, 2) and (6, 10). What is its equation in point-slope form? ​

Answers

Answer:

y - 10 = 4(x - 6)

Step-by-step explanation:

Point slope form is

y - y1 = m(x - x1) where m = slope of the line and (x1, y1) is a point on the line.

Here the slope = (10-2)/(6-4)

= 8/2

= 4.

So the equation is

y - 10 = 4(x - 6)    using the point (6, 10)

How to calculate compound interest?

Compound interest are amount of money added on amiunt invested.

Given the following parameters

P = $600
r = 8% = 0.08
t = 3 years

Using the compound interest formula

A(t) = Ao(1+r)^t
A(t) = 600(1.08)^3
A(3) = $755.83

Because angle B = Y as stated at the top we can assume triangle 2 is a smaller version of triangle 1.

Because the length of the same side on triangle 2 = 2 and on triangle 1 it = 4 we can assume triangle 2 is half the size of the first triangle.

So to find the length of s we divide 6 by 2 because triangle 2 is half the size of triangle 1.

A ball was thrown upward into the air. The height in feet of the ball, above the ground, t seconds after being thrown can be determined by the expression -16t² + 40t + 3. What is the meaning of the 3 in the expression?
A.) the ball took three seconds to reach its maximum height
B.) the ball took three seconds to reach the ground
C.) the ball was thrown from a height of three feet
​D.) the ball reached a maximum height of three feet

Answers

Answer:

The ball was thrown from a height of [tex]3\; {\rm ft}[/tex].

Step-by-step explanation:

The expression for the height of this ball, [tex]h(t) = -16\, t^{2} + 40\, t + 3[/tex], represents a parabola (with respect to time [tex]t[/tex].)

In this expression, "[tex]3[/tex]" represents the [tex]y[/tex]-intercept of the parabola- the output of the parabola when the input is [tex]t = 0[/tex]. The reason is that when [tex]t = 0\![/tex], terms of this parabola that include [tex]t[/tex] ([tex](-16\, t^{2})[/tex] and [tex]40\, t[/tex]) would evaluate to [tex]0[/tex]:

[tex]\begin{aligned}h(0) &= -16\times 0^{2} + 40\times 0 + 3 = 3\end{aligned}[/tex].

In the case of this ball, the term "[tex]3[/tex]" means that height of this ball is [tex]3\; {\rm ft}[/tex] when [tex]t = 0[/tex] (right when the ball was thrown.) Thus, the ball was thrown from a height of [tex]3\; {\rm ft}[/tex].

Answers

Using it's concept, it is found that there is a 0.0526 = 5.26% experimental probability that the next student Grayson talks to will pick orange.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem, 2 out of 38 students picked orange as their favorite color, hence the probability that the next student picks orange is given by:
