Answer:

x = 13

Step-by-step explanation:

The first step to finding x is to apply the numbers to the Pythagorean Theorem.

The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.

1. Now we have to put the known values in place of the letters.

a = 12

b = 5

c = x

2. Since the formula is squaring a, b, and c, we have to square the numbers too.

a = 12^2

b = 5^2

c = x^2

12^2, or 12 squared, is 144.

5^2, or 5 squared, is 25.

3. Next we have to add those two numbers.

144 + 25 = 169

4. Lastly, we have to square root 169

√169 = 13

Therefore, your answer is 13.

Hope this Helps!

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon lef

Nastasia [14]

Answer:

Orange ribbon Zoe use is $1\frac{3}{4} \ feet.$

Step-by-step explanation:

Given:

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon left.

Now, to find the orange ribbon Zoe use.

Let the orange ribbon Zoe use be $x.$

Total orange ribbon Zoe had = $3\frac{1}{8} = \frac{25}{8} \ feet.$

Ribbon Zoe had left = $1\frac{3}{8} =\frac{11}{8} \ feet.$

Now, to get the orange ribbon Zoe use:

$\frac{25}{8} -x=\frac{11}{8}$

Subtracting both sides by $\frac{11}{8}$ we get:

$\frac{25}{8} -x-\frac{11}{8} =0$

Adding both sides by $x$ we get:

$\frac{25}{8} -\frac{11}{8} =x$

$\frac{25-11}{8} =x$

$\frac{14}{8}=x$

$x=\frac{14}{8}$

$x=\frac{7}{4}$

$x=1\frac{3}{4}\ feet.$

Therefore, orange ribbon Zoe use is $1\frac{3}{4} \ feet.$

Find the surface area of a square pyramid whose base edge is 6cm and whose slant edge is 5cm

dmitriy555 [2]

Check the picture below.

so let's notice, the base is a 6x6 square, and triangular faces have a base of 6 and an altitude/height of 5. So we can just get the area of the square and the triangles and sum them up and that's the area of the pyramid.

$\bf \stackrel{\textit{triangles' area}}{4\left[ \cfrac{1}{2}(6)(5) \right]}+\stackrel{\textit{square's area}}{(6\cdot 6)}\implies 60+36\implies 96$
