I’m not completely sure but i don’t think so. triangle ABC should be equal to 180°. this is equal to 190 °.
It depends on the type of equation
Answer:
510 gorillas
Step-by-step explanation:
In this problem, the population of gorillas is decreasing at a rate of 3.5 % per year.
We can write an expression for the population of gorillas as follows:
where
n(t) is the number of gorillas after t years
is the number of gorillas at t = 0
r is the grow rate of the population
t is the number of years
Here we have:
is the number of gorillas when t = 20 years
is the grow rate of the population
So the equation becomes:
And solving for , we find the initial number of gorillas:
Answer:
A knife costs £2.88.
Step-by-step explanation:
Create two equations using what you know to show the problem.
k = 2s
12k + 8s = 46.08
Substitute the first equation in for k, then isolate s to find how much spoons cost.
12(2s) + 8s = 46.08
24s + 8s = 46.08
32s = 46.08
s = 1.44
A spoon costs £1.44. To find the price of a knife, double the cost of a spoon:
1.44 * 2 = 2.88
A knife costs £2.88.
