9)To find the LCD you need to find a number that all of the denominator numbers can divide into, for this problem it would be 12. 12/6+12/4+12/3=1
2+3+4=1
9=1
No solution
10) In order to solve this problem you need to cross multiply
2(3x+5)=7(10
6x+10=70
6x=60
x=10

An architect planned to construct two similar stone pyramid structures in a park. The figure below shows the front view of the p
Sav [38]

Since the architect wants similar figures, it comes from the definition of similar triangles that the ratio of corresponding sides (all 3 sides) should be equal.

So,

\frac{7.5}{6}= \frac{5}{4}= \frac{10}{CB}.

Let's find CB.

\frac{7.5}{6} =\frac{5}{4}= \frac{10}{CB}\\ 1.25=1.25=\frac{10}{CB}\\ 1.25=\frac{10}{CB}\\ 1.25CB=10\\CB=\frac{10}{1.25}\\ CB=8

So, CB should be 8. Option C is correct.


ANSWER: Change the length of side CB to 8 feet

Kayson is looking at two buildings, building A and building B, at an angle of elevation of 73°. Building A is 30 feet away, and
grigory [225]

Answer:

The correct option is:

Building B; it is around 16.35 feet taller than building A.

Step-by-step explanation:

Consult the diagram below where the first figure represent building A and second figure represents building B

For building A:

tan θ = Perpendicular / Base

tan 73° = Height of building A / 30

Height of building A = tan73 · 30

Height of building A = 98.13 ft

For building B:

tan θ = Perpendicular / Base

tan 73° = Height of building B / 35

Height of building A = tan73 · 35

Height of building A = 114.48 ft

Building B is taller

Difference in height = height of building B - height of building A

Difference in height = 114.48 - 98.13 = 116.35 feet
