Answer:

Length of width in the blueprint is 3.5 inches

Step-by-step explanation:

We have given dimensions of a room as 18ft long by 18ft wide.

To represent this room dimensions in a blueprint, the dimensions of room is re-scaled as :

By length it is represented as 3.5 inches long

So we can find scaling factor here as:

Scaling factor = 3.5 / 216    (Since 18 ft = 216 inches)

Scaling factor = 7/432

Now, to get width of room in the blueprint,  we multiply actual length of width by the scaling factor.

Length of width in blueprint = scaling factor * width(in inches)

Length of width in blueprint = (7/432 ) * 216     , (Since 18ft = 216 inches)

Length of width in blueprint = 3.5 inches

So we get length of width in blueprint is 3.5 inches

A<br> 1200<br> b<br> 3200<br> c<br> 3680<br> d<br> 5520
anygoal [31]

Answer:

c. 3680

Step-by-step explanation:

In 2010, the population was 8000.

In 2014, it increased by 15%.

Population in 2014 :

= 8000 + 15/100×8000

= 8000 + 1200

= 9200.

Now, 2/5 of the population was age 12 or under.

= 2/5 × 9200

= 2×1840

= 3680

Answer - c) 3680

Find the zeros of polynomial function.<br> f(x)=x^2-x-90
Fofino [41]

First step is to factor. With a polynomial function in the form ax² + bx + c = f(x), we have to find what factors of term C have a sum of term B.

So with this, we need factors of -90 add up to become -1. Your factors are - 10 and 9.

f(x) = x² + 9x - 10x - 90

Now we group together and pull out GCFs.

f(x) = (x² + 9x) + (10x - 90)

f(x) = x(x² + 9) - 10(x + 9)

f(x) = (x - 10)(x + 9)

Now, set each factor equal to zero.

x - 10 = 0, x + 9 = 0

For the first equation you are going to add 10 to both sides to get x by itself. Subtract 9 from both sides in the second equation for the same reason.

x = 10, x = -9

Your zeros are at x = -9, 10 or at the ordered pairs (-9, 0) and (10, 0).

Which of the following theorems proves that abc~def?
GaryK [48]

Answer:

D but read below.

Step-by-step explanation:

I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.
