Answer:
6
Step-by-step explanation:
You have to add like terms. So the 5n and -5n would cancel each other out (because 5-5=0) and 9-3=6.
Answer:
Last week the owner spend <u>$42.32</u> on waffle cones.
Step-by-step explanation:
Given:
An ice cream shop owner pays $0.12 per regular cone and $0.23 per waffle cone. Customers are allowed to choose which type of ice cream cone they would prefer.
If two thirds of the 276 vibes sold last week were waffle cone.
Now, to find the amount the owner spend on waffle cones last week.
Last week waffle cone sold were = 
<u><em>Last week number of waffle cones sold were = 184.</em></u>
<u><em>Price of per waffle cone = $0.23.</em></u>
Now, to get the owner spend on waffle cones last week we multiply last week number of waffle cones sold were by price of per waffle cone:
Therefore, last week the owner spend $42.32 on waffle cones.
Answer:
$109
Step-by-step explanation:
<u>Formulas</u>
interest = (principal amount)(rate)(time)
<em>interest = (100)(0.09)(3) = $27</em>
total = principal amount + interest
<em>total = 100 + 9 = $127</em>
Answer:
Actual distance between two city = 40 miles
Step-by-step explanation:
Given sample size;
1 inch = 10 miles
Distance between two city = 4 inch
Find:
Actual distance between two city
Computation:
Actual distance between two city = Sample size of 1 inch in miles x Distance between two city
Actual distance between two city = 4 x 10
Actual distance between two city = 40 miles
Answer: year 1948
Step-by-step explanation:
1900 is our t = 0
The population of Greenville can be written as:
G = 4000 + 100*t
the equation for Springfield can be written as:
S = 1000*(1.04)^t
we want to find the value of t that makes S(t) = G(t)
4000 + 100*t = 1000*(1.04)^t
(4000 + 100*t) = 1.04^t
4 + 0.1*t = 1.04^t
now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:
4 = 1.04^t - 0.1*t
You will find that the correct value is t = 48
So we can assume that in year 1948 the populations will be about the same.
