Answer:
125 blue vehicles
Step-by-step explanation:
In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.
Now to solve this question, we are going to treat the sample numbers as a ratio.
The ratio here is thus 7 black to 5 blue I.e 7:5
We have 300 vehicles, we now want to estimate the number of blue vehicles present.
From the sample ratio, there are a total of 12 vehicles
Now the total number of blue vehicles would be 5/12 * 300 = 125
There are 125 blue vehicles
The annual salary of Mrs. Fredrick is $ 39397.2
<u>Solution:</u>
Given, Mrs. Frederick is paid semimonthly.
Her semi-monthly salary is $1.641.55.
Now, let us find her monthly salary first.
<em>monthly salary = 2 x semi – monthly salary </em>
So, monthly salary = 2 x 1,641.55 = $ 3283.1
Since there 12 months in a year, we obtain the annual salary as follows:
Now, the<em> annual salary = 12 x monthly salary </em>
Annual salary = 12 x 3283.1 = $ 39397.2
Hence, the annual salary of Mrs. Fredrick is $ 39397.2

Answer:
200.96
Step-by-step explanation:
So, we have to find the area of both.
The area for the mat is
(pi)12^2=3.14x144. However, since it is HALF a circle, we divide it by two.
So, 226.08
Next, the water bowl.
(3.14)4^2=50.24.
226.08-25.12=200.96
I may be wrong!
