Help me out plssss thank u

x = 44°

Step-by-step explanation:

Since AB is a diameter,

arcAC + arcCB = 180

92° + arcCB = 180

or

arcCB = 88°

ArcCB is the intercepted arc and by definition, the inscribed angle x is half the measure of the intercepted arc. Therefore,

x = (1/2)arcCB

= 44°

Find the LCD of Number 21 and 23.
Alina [70]
The LCD is basically the LCM of the denoenator so

to find LCM of exg 6 and 21, find factors and group
6=2 and 3 (one 2 and one 3)
21=3 and 7 (one 3 and one 7)
lcm=2 and 3 and 7 (include 6 and 21 in the number) (one 2 and one 3 and one 7)

LCM≈LCD
so
17.
denomenators are 2 and x^2
2=2
x^2=x times x
lcm=2 times x times x=2x^2


18.
denomenators are 6 and 9
6=2 and 3
9=3 and 3
LCM=2 times 3 times 3=18

19.
denomenators are z and 7z
z=z
7z=7 and z
lcm=7 times z=7z


20. 
denomenators are 5b and 7b^3c
5b=5 and b
7b^3c=7 times b times b times b times c
LCM=7 times 5 times b times b times b times c=7b^3c=7cb^3

21. denomenator=5 and x+2
5=5
x+2=x+2
LCM=5 times (x+2)=5(x+2)=5x+10


22. denomenators are ab and b^2c
ab=a time b
b^2c=b times b times c
LCM=a times b times b times c=ab^2c=acb^2

23. demonenators are m+n and m-n

m+n=m+n
m-n=m-n
LCM=(m+n)(m-n)=m^2-n^2


24.denoenators are k and k^2-2

k=k
k^2-2=k^2-2
LCM=k times (k^2-2)=k^3-2k

You require space to serve 65 vehicles at any one time. Will a facility measuring 145ft by 130ft be adequate if each vehicle req
Hunter-Best [27]

Answer: No, it is not sufficient to serve 65 vehicles as it can only serve 62 vehicles with this space

Step-by-step explanation:

Since we have given that

Dimensions of space where vehicles are stored is

145 feet by 130 feet

Number of vehicles to serve = 65

Area required for each vehicle = 300 ft²

So, we need to find that is it sufficient for to serve 65 vehicles.

So, first we find the number of vehicles can be served in this space

\text{ Number of vehicles}=\frac{\text{ Area of space}}{\text Area of space required for one vehicle }}\\\\=\frac{145\times 130}{300}\\\\=\frac{18850}{300}\\\\=62.83\\\\=62\ approx

No, it is not sufficient to serve 65 vehicles as it can only serve 62 vehicles with this space.
