Answer: 49\ ft^2

Step-by-step explanation:

The formula that is used to calculate the area of a square is this one:

A=s^2

Where "s" is the side lenght of the square

You know that Julia used 1 foot square stone tiles, then each side lenght of the this tiles is:

s_{tile}=\sqrt{1\ ft^2}\\\\s_{tile}=1\ ft

Since Julia laid 7 tiles wide by 7 tiles long, the side lenght of the new patio is:

s_{patio}=7(1\ ft)\\\\s_{patio}=7\ ft

Therefore its area is:

A_{patio}=(7\ ft)^2\\\\A_{patio}=49\ ft^2

Could you build a triangle from each of the 3 lengths?
lianna [129]
To form a triangle the sum of the two shorter sides must be greater than the longest side.
5, 5, 3 forms a triangle (isosceles)
8, 8, 8 forms a triangle (equilateral)
5, 6, 10 forms a triangle (obtuse angled scalene)

7, 8, 15 technically forms a triangle with an area of zero units. The vertices would be co-linear.
This will often be ignored as it has little practical use.

Fun fact. If you break a stick into 3 random lengths there is only a 25% chance they will be able to form a triangle.

How do I solve this, it's not 10
guapka [62]

Answer:

26.7

Step-by-step explanation:

This is the answer because 26.7/20 = (16+26.7)/32

When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.

To solve, you create a formula.

(16+x)/32=x/20

Multiply both sides by 32 to get rid of the 32 in the left side.

16+x=32x/20

Multiply both sides by 20 to get rid of the 20 right side.

320+20x=32x

-20x on both sides to get all the variables on one side and all the nukbers on the other.

320=12x

Divide both sides by 12 to get x by itself

x=26.66667

Write an equation of the line that passes through (−3,7) and is perpendicular to the line y=−2x−5.
Murljashka [212]

Answer:

Step-by-step explanation:

an equation is : Use the point-slope formula.

y - y_1 = m(x - x_1)    ;  m : the slope   when : x_1 = -3   and  y_1  = 7

- 2 ×m = - 1  because this line is perpendicular to the line y= -2x-5 when the slope is  -2

so : m= 1/2

an equation is : y - 7 =(1/2)(x+3)
