What is the scale of a drawing in which a 9ft wall is 6cm long?

Mathematics

Orlov [11]3 years ago

Answer:

.022

Step-by-step explanation:

If you scale something you basically multiply it by something.  if you draw something at two times the scale, you are doubling it.  so 9 ft would be scaled up to 18 foot.  if you draw it at half the scale you cut it in half, so 9 would be 4.5.

The question is asking what do you multiply 9 feet by to get 6 cm.  Now, it's not just 9 to 6, but feet to centimeters.  A quick googling says the conversion is 1 foot = 30.48 centimeters.  so 30.48*9 gets us 9 feet is 274.32 cm.  So now we can simply find the scale factor between 274.32 cm to 6 cm.  Since it is decreasing we know it is going to be less than 1.  You basically use algebra though.  what do you multiply 274.32 by to get to 6?

274.32x = 6

x = 6/274.32

x = .022

So the scale factor is about .022

A bearing, measured at 1.234 inches with a caliper, must be replaced. Since the bearings are sized in 64ths of an inch, find the
Ganezh [65]
We have
1.234 in-----> 1+(0.234) in

we know that
1/64=0.015625
so
0.234/0.015625=14.98-----> 15
15/64-----> 0.234

therefore
1.234 in is equal to -----------> 1 15/64 in

the answer is
1 15/64 in

X, Y and Z are three points on a map. Y is 43km and on a bearing of 041° from X. Z is 67km and on a bearing of 117° from X. Calc
Helen [10]

Answer:

70.3km

Step-by-step explanation:

When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x

i.e 117-41 = 76

Using cosine rule,

YZ²= 43² + 67² - 2 x 43 x 67

cos76

YZ= √4944

= 70.3

This is the previous problem: A rabbit started at point 0 and made 3 jumps a jump of 4 units then a jump of 2 units and then a j
morpeh [17]

Answer:

Q1: The rabbit could be at eight different numbers of the number line: -7, - 5, - 3, - 1, 1, 3, 5, and 7.

Q2: 13

Step-by-step explanation:

Q1: Let's simulate each of the jumps of the rabbit in all the possible directions, as follows:

Option 1: - 4 - 2 - 1 = -7

Option 2: - 4 - 2 + 1 = -5

Option 3: - 4 + 2 - 1 = - 3

Option 4: - 4 + 2 + 1 = - 1

Option 5:  4 - 2 - 1 = 1

Option 6: 4 - 2 + 1 = 3

Option 7: 4 + 2 - 1 = 5

Option 8: 4 + 2 + 1 = 7

Q2: If the rabbit started at 10 you would add 3 to 10 and get 13.
