<h3>Answer:  110 square miles</h3>

=============================================================

Explanation:

There are a few ways to do this.  

One method involves drawing a horizontal line to form three rectangles as show below. Note the labels A,B,C.

  • Rectangle A in the upper left corner has area of base*height = 6*7 = 42 square miles. I'll let A = 42 since we'll use it later.
  • Rectangle B is 20 miles across horizontally (base) and 2 miles tall vertically (height). The 2 miles is from 9-7 = 2. The area of rectangle B is 20*2 = 40 square miles. Let B = 40.
  • Then finally, C = 28 because rectangle C is 4 miles across and 7 miles tall, so 4*7 = 28.

Add up those three sub areas found: A+B+C = 42+40+28 = 110 square miles

----------------

There are other methods you could do. A second method is to draw two vertical lines to form 3 other rectangles, then add up the sub areas to get 110.

A third method is to draw a horizontal line across the top to form one large rectangle (20 mi by 9 mi) and subtract off the area of the 7 mi by 10 mi inner rectangle (the empty space), so you'd say 20*9 - 7*10 = 180-70 = 110

First do inside the parenthesis first.

When dividing two exponents subtract them.

15-5 = 10

So w^15 / w^5 becomes w^10


Now you have (w^10)^4

Now multiply the exponents:

10 x 4 = 40

Final answer is w^40

4. Find the value of x &amp; y from the following equation 4x+5y=90, x+y=20 a. 10, 15 b. 10, 5 c. 10, 8 d. 10, 10​
ira [324]

An equation is formed of two equal expressions. In the two of the given equations, the value of x and y are 10 and 10, respectively. The correct option is D.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the two of the equation, which can be named as,

4x+5y=90   ...... equation 1

x+y=20   ............ equation 2

Solve the second equation for x,

x + y = 20

x = 20 - y ................ equation 3

In the first equation substitute the value of x from the third equation,

4x + 5y = 90

4(20 - y) + 5y = 90

Solving the equation for y,

80 - 4y + 5y = 90

y = 90 - 80

y = 10

Substitute the value of y in the second equation, to get the value of x,

x + y = 20

x + 10 = 20

x = 20 - 10

x = 10

Hence, In the two of the given equations, the value of x and y are 10 and 10, respectively.

Express p as the subject of the formula<br>q= p² - r ÷ t​
Rudik [331]

Answer:

p = \sqrt{q +\frac{r}{t} }

Step-by-step explanation:

q=p^{2}- r÷ t   using BODMAS

q = p^{2} - (r/t)

q + r/t = p^{2}

p=\sqrt{q+\frac{r}{t} }

The length of a rectangle is 24 units.can the preimteter p of the rectangle be 60 units when it’s width w is 11 units?
Alenkinab [10]
No it can’t because calculating the perimeter, you would have to add all sides of the rectangle. If you added 11 + 11 + 24 +24, the perimeter would be 70 not 60.
