Hi DerpyIntelligence!
The product is addition so we do -3 1/4+-1 1/2. We solve it like this. We separate each part like this (-3)+(-1/4)+(-1)+(-1/2) then we solve the whole parts (-3)+(-1)=(-4). Next we find out the LCD of (-1/4) and (-1/2) which is 4 so we change (-1/2) to (-2/4) than we add (-1/4) which is (-3/4). Finally we add the wholes to the fractions (-4)+(-3/4)=(-4 3/4)
Hope this helps!
Answer:
a) 10,500 big cats
b) 13,401 big cats
c) 33 years
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form; 5/100= 0.05)
t= years
A = population after t years
Replacing with the values given:
a) At 2005, 1 year passed since 2004 (t=1)
A = 10,000 (1+ 0.05)^1
A = 10,500 big cats
b)
At 2010, 6 years passed since 2004 (2010-2004= 6)
A = 10,000 (1+ 0.05)^6
A = 13,401 big cats
c)
50,000 < 10,000 (1+ 0.05)^t
Solving for t:
50,000/10,000 < 1.05^t
5 < 1.05^t
log 5 < log 1.05^t
log 5 < t ( log 1.05)
log 5 / log 1.05 < t
32.9 years < t
33 years = t

74 = 20(2.5) + 20(x)
74 = 50 + 20x
74-50 = 20x
24 = 20x
24/20 = x
1.2 = x
x = 1.2 yards of red felt
Answer:
Step-by-step explanation:
Let the number be x
14 ÷ x = 
48 is the base, the area of each triangle is 44
multiply that by 4 = 176
176+48=224
