Answer:

302.02 units²

Step-by-step explanation:

To do this, we can first solve for the height of the trapezoid. We can do this using sin:

sin 70= \frac{x}{14}

14· sin 70≈13.16

Now, we can solve for the base of the small triangle on the right by:

cos 70= \frac{x}{14}

14 · cos 70 ≈4.79

Now, find the area of the triangle using V= \frac{1}{2} bh:

V= (4.79)(13.16)/2≈30.86

Now, we can find the area of the rectangle in the middle by:

15· 13.16 (the height)= 197.4

Now, we need to solve for the triangle on the left. We will need to first find the base by subtracting the bases of the other figures from 31:

31-4.79-15= 11.21

Now, find the area of the triangle:

V=(11.21)(13.16)/2= 73.76

Add all of the areas, giving you:

73.76+30.86+197.4= 302.02 units²

Marta bought new fish for her home aquarium. She bought 3 guppies and 2 platies for a total of $13.95. Hank also bought guppies
ratelena [41]
Hank bought same guppies as Marta but 2more platies so
18.33-13.95=4.38
2platies=4.38
4.38/2=2.19
2.19 price of platies
13.95-4.34=9.61
9.61/3=3.20
3.29 price of guppies

The cell labelled a is a joint frequency of 48 and the cell labelled b is a marginal frequency of 93.

<h3>What is a frequency table?</h3>

The frequency of an occurrence or a value is the number of times it happens. A frequency table is a list of objects with the frequency of each item shown in the table.

The data is mentioned in the table given below:

We need to find the value of a and b.

Here, Cell Phone+No Cell Phone=Total

To find a:

Add the no lap entries, that is 159+a=207

⇒a=48

To find b:

Add the lap entries, that is 82+11=b.

⇒b=93.

Therefore, the cell labelled a is a joint frequency of 48 and the cell labelled b is a marginal frequency of 93.

Well for the small box of Cornflakes you want to divide $6.30 by 18 and you should get $0.35 which is how much each oz cost.

For the large box you want to convert 2.2 lb to oz, you will get 35.2 oz. Next just do the same divide $8.80 by 35.2 and get $0.25 which is the cost for each oz in the large box.
