Answer:
Leena consumed 1,500 calories at dinner
Step-by-step explanation:
The reason the answer is Leena consumed 1,500 calories at dinner is because she consumes 2/3 of her daily calories at dinner.
Since that angle all together is 180, 100 is 2z-10 and z is 55
Rewrite it to simplify using order of operations.
P E M D A S
() ^2 × ÷ + -
So nw it's
5-1-(9÷3)-9
no now it's
(5-1)-(3-9)
4-(-6) I wrote the negative in parentheses to show its not an additional subtraction sign. also if you look it's sort of a plus sign. so when you subtraction (-6) from 4 it's actually 4+6
4-(-6)=10.
that's what I got. hope this helps.
Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
x ----> is the number of years since 2009
y ----> is the population of bears
a ----> is the initial value
b ---> is the base
step 1
Find the value of a
For x=0 (year 2009)
y=1,570 bears
substitute


so

step 2
Find the value of b
For x=1 (year 2010)
y=1,884 bears
substitute



The exponential function is equal to

step 3
How many bears will there be in 2018?
2018-2009=9 years
so
For x=9 years
substitute in the equation


92% is the amount that are perfect
