here we are told that
number of dolls sold varies directly with advertising costs
number of dolls varies inversely with price of a doll
so initially
1800 dolls sold when advertising costs were $ 34 000
and price of a doll was $ 25
next they increased the advertising costs to $ 42 000
as we know number of dolls sold varies directly with advertising costs
so here when the advertising costs increase the number of dolls sold too should increases as its directly proportional relationship
we arent told that the price of a doll is changed so there's no effect on the number of dolls sold due to changes in price of a doll
only effect on number of dolls sold is due to increase in advertising costs
increase in advertising cost leads to increase in number of dolls sold
from the given options, only in one option the number of dolls sold are more than 1800 dolls. option is C with 2224 dolls
therefore correct answer is C. 2224 dolls
Answer:
See Below
Step-by-step explanation:
The surface area of cylinder is given by the formula:
Where
r is radius ( diameter is 4, so radius is 4/2 = 2)
h is height ( h = 9)
Lets find original surface are:
<u>Halving diameter:</u>
diameter would be 4/2 = 2, so radius would be 2/2 = 1
So, SA would be:
<u>Halving height:</u>
Height is 9, halving would make it 9/2 = 4.5
Now, calculating new SA:
Original SA is 
,
Halving diameter makes it 
Halving height makes it 
So, halving diameter does not have same effect as halving height.
There are 52 weeks in a year. 1 frog per week: 52 * 1 = 52
So, cloning about 1 frog per week would be reasonable.
We can use pythagorean theorem:
a^2 + b^2 = c^2
4 + 9 = c^2
13 = c^2
sqrt of 13 = c
Hope this helps!
Answer:
f=11
Step-by-step explanation:
If t=7, we can substitute it into the original equation:
f=(2)(7)-3
Simplify:
f=14-3
f=11
