Answer:
24 drinks
Step-by-step explanation:
Multiply the number of packages of drinks (3) times the number of drinks in each pack (8)
3*8=24
Answer:
Step-by-step explanation:
This can be represented as exponential decreasing function.
y = a(1 - r)t
a = starting amount
r = rate
t = years
y = 1600(1 - .0725)15
= 1600(.9275)15
= 1600(.32337673)
= 517.40
In 15 years, the forest will shrink in size to 517.40 km2
Answer:
D
Step-by-step explanation:
Any set of three angles that add up to 180 degrees can form a triangle.
Answer:
Now: 6 yr mean age
in 10 yrs? 16 yr mean age
in 20 yrs? 26 yr mean age
Why? Because regardless of the relationship between each sibling's age, your always adding the 10yrs to each individual, which you are then dividing out to determine the mean age. See proof below:
Including anita, there are 6 people. We'll define each age as an unknown variable. Assume we know nothing about the relationships between their ages
for example sake
anita's age = a
sister 1's age = b
sister 2's age = c
brother 1's age = d
brother 2's age = e
brother 3's age = f
Now:
mean age = (a + b + c + d + e + f)/(6 people) = 6 yrs
in 10 yrs:
mean age = ((a+10) + (b+10) + (c+10) + (d+10) + (e+10) + (f+10))/(6 people)
mean age = (a + b + c + d + e + f + 60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + (60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + 10
Notice the first term is the same expression of the mean age for "Now"
Thus, in 10 yrs:
mean age = 6 + 10 = 16 yrs
The same principle applies for "x" yrs from now, as long as we know what the mean age is "Now"
Answer:
C. 0.6625 square inches
Step-by-step explanation:
To get the area of the net of a square pyramid;
We need to find the are of the square base and the area of the four triangles;
Area of the square base = s²
= (0.25 in)²
= 0.0625 in²
Area of one triangle = 0.5 × b × h
= 0.5 × 0.25 in × 1.2 in
= 0.15 in²
Area of the four triangles = 0.15 in² × 4
= 0.6 in²
Therefore;
Area of the net square pyramid = 0.0625 in² + 0.6 in²
= 0.6625 square inches
