Hey love! <3

Answer:

Your answer is 306 units^2!

Step-by-step explanation:

Let's work this out together!

First let's find the top and bottom square's area.

6 x 15 = 90

Since there are not only two of those shapes but THREE, 90 x 3= 270.

So 270 is the surface area of the middle rectangles.

Step 2! Let's find the area of these triangles. We know that both of the triangles are 6 on each side.

Think back to geometry formulas. The formula for finding the area of a triangle is different then a square.

Triangle formula: Base x Height / 2 = A

Rectangle formula: Base x Height = A

So 6 x 6 is 36, now we have to divide it by two; which equals 18.

Since there are TWO triangles, we multiply 18 by two giving us the total surface area of the triangles, 36.

Now let's add our products together!

36 + 270 = 306

Thus the total surface area being 306 units^2

Answer:

$\large \boxed{\sf \text{The rate of the boat is } 53 \ km/h \text{, the rate of the current is }8\ km/h \ \ }$

Step-by-step explanation:

Hello, let's note v the rate of the boat and r the rate of the current. We can write the following

$\dfrac{135}{v-r}=3=\dfrac{183}{v+r}$

It means that

$135(v+r)=183(v-r)\\\\135 v + 135r=183v-183r\\\\\text{ *** We regroup the terms in v on the right and the ones in r to the left***}\\\\(135+183)r=(183-135)v\\\\318r=48v\\\\\text{ *** We divide by 48 both sides ***}\\\\\boxed{v = \dfrac{318}{48} \cdot r= \dfrac{159}{24} \cdot r}$

But we can as well use the second equation:

$3(v+r)=183\\\\v+r=\dfrac{183}{3}=61\\\\\dfrac{159}{24}r+r=61\\\\\dfrac{159+24}{24}r=61\\\\\boxed{r = \dfrac{61*24}{183}=8}$

and then

$\boxed{v=\dfrac{159*8}{24}=53}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Answer: any number that’s not already used

Step-by-step explanation: It could be any number as long as it hasn’t already been used in that data set. Mode is the most occurring value, and there’s no mode when all numbers are different. Hope this helped;)
