Answer:
Step-by-step explanation:
Let :
C = number of cats
D = number of dogs
Raul's pet store has a play area that can fit up to 30 cats and dogs.
C + D = 30
The pet store never has more than 8 cats in the play areas.
<h2>
C < 9</h2>
(there can never be 9 or more cats)
As or the number of dogs :
C + D = 30
C = 30 - D
Since we know that C < 9. To get the number of dogs allowed, we just plug in 30 - D for C.
30 - D < 9
30 - 9 < D
or
<h2>
D > 21</h2>
(dogs have to be 22 or more)
Answer:
Option (C)
Step-by-step explanation:
"If the two secants are drawn to a circle form an external points then the product of the measures of one secant segment (inside the circle) and its external segment will be equal to the product of measures of the other secant's segments."
By this property,
8(8 + x) = 9(9 + 7)
64 + 8x = 144
8x = 144 - 64
8x = 80
x = 10
Therefore, Option (C) will be the answer.
Answer:
4. 50.19°
5. 25.19°
Step-by-step explanation:
4. Reference angle = x°
Opposite = 6 units
Adjacent = 5 units
Thus,
(nearest hundredth)
5. Reference angle = x°
Opposite = 48 - 5.2 = 42.8 ft
Adjacent = 91 ft
Thus,
(nearest hundredth)b
Answer:
140 degrees.
Step-by-step explanation:
Because BD is a tangent to the circle the angle ABD = 90 degrees.
So m < BAD = 180 - 90 - 50
= 180 - 140 = 40 degrees. ( as there is 180 degrees in a triangle).
So m < BAF = 180 - 40 = 140 degrees (adjacent angles).
A) -3.5*2^2*3=-14*3=-42
c) -3*y*z^2=-3*(-4)*3^2=12*9=108
6x*y^2=6*2*(-4)^2=12*16=192
P=2*(108+192)=2*300=600
b) 5/2*(-4)^2=5/2*16=40
