maths j2 a road is 300km long is drawn to a scale of 1cm represents 50km . what is it's length on drawing?​

Answers

Answer 1

Answer: 6cm.

Step-by-step explanation:

Strategy 1 (in-head thinking)

300 divided by 50 would be 6, multiply 6 by 1 and get 6cm.

Strategy 2 (proportions)

First, set up a proportion.

We know that 1cm = 50km, so we put them on a fraction (whichever is denominator/numerator doesn’t affect the process)

However, we don’t know how much cm equals 300km, so we turn that into a variable, in this case x.

1cm       x cm

———   ———

50km  300km

To solve a proportion, go diagonal to where the variables have already been filled in. You can’t so 50km and x cm, as you don’t know x. You can do 300km however. To start, multiply 1 and 300, to which you get 300. Then, multiply 300 by the 50km and you’ll get x. That’ll equal to 6.

So in conclusion, your answer is 6.

Oh no! He seems to be missing some parts though. He was "robbed" of his
asymptotes.
Luckily, he can remember what they were:
1. This functions vertical asymptote was x=-5.
2. This functions horizontal asymptote was y = 12.
Please recreate this function with those identifying features! Please make sure it
looks like the function in the picture

Answers

Let's do

[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x-h}+k[/tex]

Release k for some while

If

we take h=0

So

y=3/x

So vertical asymptote is at origin now

It mentioned that it's at x=-5 so we need to change x

put -5 in place of h

[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x-(-5)}[/tex]

[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x+5}[/tex]

Vertical asymptote at x=-5

Now

for k=0 horizontal asymptote at origin

But it's given

y is at 12

Same put y=12 in place of k

[tex]\\ \rm\dashrightarrow y=\dfrac{3}{x+5}+12[/tex]

h=-5k=12

Graph attached for verification

Answer:

h(x)=3/x+5 +12

Volume of a box If a box has a volume of 42 cubic feet, is it possible for you to
fit inside the box? Explain your answer

Answers

Answer:

yes ,because the average human hight

Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.

What is a box?

In mathematics, a box is a three-dimensional shape that has six rectangular faces.

It is also called a rectangular prism.

The faces on opposite sides of a box are congruent and parallel. A box has a height, width, and length, which are usually labeled as h, w, and l.

The volume of a box can be found by multiplying its length, width, and height: V = l × w × h.

We have,

The volume of a box is a measure of the amount of space inside the box, typically measured in cubic units such as cubic feet or cubic meters.

If a box has a volume of 42 cubic feet, it is simply telling us the amount of space inside the box.

Whether a person can fit inside the box or not depends on the size of the box and the size of the person.

Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.

So,

We need more information to answer this question.

is the best approximation for how many customers that month select a black frame?
A. 367 customers
B. 733 customers
C. 1, 100 customers
D. 1. 167 customers

Answers

Answer:

B. 733 customers

Step-by-step explanation:

15+30+45=90

since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)

Evaluate the piecewise function by matching the domain values with the range values.

Answers

The subfuctions of the piecewise function f(x) are linear functions

The matching values of the domain values with the range values are

x       f(x)

-4      -7

-2      -8

0       -2

2       4

4      -4

8     -12

How to evaluate the piece-wise function?

The function is given as:

[tex]f(x) = \left[\begin{array}{cc}x-3&x\le-4\\3x-2&-4 < x\le 2\\-2x+4&x > 2\end{array}\right][/tex]

The above definition means that:

All x values less than or equal to -4 would be evaluated using f(x) = x - 3All x values greater than -4 but less than or equal to 2 would be evaluated using f(x) = 3x - 2All x values greater than 2 would be evaluated using f(x) = -2x + 4

Using the above highligts, we have:

f(-4) = -4 - 3 = -7

f(-2) = 3(-2) - 2 = -8

f(0) = 3(0) - 2 = -2

f(2) = 3(2) - 2 = 4

f(4) = -2 * 4 + 4 = -4

f(8) = -2 * 8 + 4 = -12

So, the matching values are

x       f(x)

-4      -7

-2      -8

0       -2

2       4

4      -4

8     -12
