Which scale would produce the smallest drawing

Mathematics
1 answer:
Natali5045456 [20]3 years ago
6 0

Answer:

1 Millimeter: 1 meter

Step-by-step explanation:

a)  the scale is \frac{1}{100}

That means ----> 1 unit in the drawing represent 100 units in the actual

b) the scale is  \frac{1}{1}\frac{mm}{m}

Remember that

1 m=1,000 mm

substitute

\frac{1}{1,000}\frac{mm}{mm}=]\frac{1}{1,000}

That means ----> 1 unit in the drawing represent 1,000 units in the actual

c) the scale is  \frac{1}{10}\frac{in}{ft}

Remember that

1 ft=12 in

substitute

\frac{1}{10}\frac{in}{ft}=]\frac{1}{120}

That means ----> 1 unit in the drawing represent 120 units in the actual

<em>Example</em>

If we would like to draw a segment that in reality measures 1000 units, then

with scale a) \frac{1}{100}

The length of the drawing is 1,000/100=10 units

with scale b) \frac{1}{1,000}

The length of the drawing is 1,000/1,000=1 unit

with scale c) \frac{1}{120}

The length of the drawing is 1,000/120=8.3 units

therefore

The smallest drawing is with the scale of  \frac{1}{1,000}

so

1 Millimeter: 1 meter

Find an equation of the line that has the given slope and contains the given point. m=7/3 (1,6)
iris [78.8K]

The point-slope form:

y-y_1=m(x-x_1)

We have the point (1, 6) and the slope m = 7/3. Substitute:

y-6=\dfrac{7}{3}(x-1)      <em>use distributive property</em>

y-6=\dfrac{7}{3}x-\dfrac{7}{3}          <em>add 6 to both sides</em>

y=\dfrac{7}{3}x+\dfrac{11}{3}        <em>multiply both sides by 3</em>

3y=7x+11           <em>subtract 7x from both sides</em>

-7x+3y=11         <em>change the signs</em>

7x-3y=-11

Answer:

point-slope form: y-6=\dfrac{7}{3}(x-1)

slope-intercept form: y=\dfrac{7}{3}x+\dfrac{11}{3}

standard form: 7x-3y=-11

Pound is the unit of measure of passengers car weight

According the statement

The weight of passengers car is 4.5 times 10 superscript 3 units.

from this it is clear that the in simple terms the weight become 4.5 * 10^3

AND

the term 10^3 is used when we measure the weight in pounds.

So, Pound is the unit of measure of passengers car weight.

Suppose you know that Mr. and Mrs. Vincent have at most eight children. One day you happen to meet two girls who were the Vincen
lianna [129]

Answer:

The number of children are 4 out of which 3 are girls

Step-by-step explanation:

Data provided in the question:

P(Two randomly selected children are girls) = \frac{1}{2}

now,

let the number of children be 'n'

the number of girls be 'x'

thus,

P(Two randomly selected children are girls) = \frac{^xC_2}{^nC_2} = \frac{1}{2}

also,

^nC_r = \frac{n!r!}{(n-r)!}

thus,

\frac{\frac{x!2!}{(x-2)!}}{\frac{n!2!}{(n-2)!}} = \frac{1}{2}

or

\frac{x(x-1)}{n(n-1)}=\frac{1}{2}

or

2x(x-1) = n(n-1)

now

for x = 3 and n = 4

i.e

2(3)(3-1) = 4(4-1)

12 = 12

hence, the relation is justified

therefore,

The number of children are 4 out of which 3 are girls
