Answer:

Length of base (a) = 5 units

Total Surface Area of Pyramid (T.S.A.) = ?

Now,

T.S.A. = Area of four triangles + Area of base

= $4(\frac{\sqrt{3} }{4})(5^{2}) + 5^{2} = 25\sqrt{3} + 25$ ≈ $68.301sq. units$

How many miles equals 26 km

Sliva [168]

Given data:

The given distance is d=26 km.

We know 1 kilometer is equal to approx 0.621 miles.

1km= 0.621 miles

Multiply the above expression with 26 on both sides.

26(1 km)= 26(0.621 miles)

26 km= 16.146 miles.

Thus, 26 kilometer is equal to 16.146 miles

A triangle has sides xcm, (x + 4) cm and 11cm, where x is a whole number of cm. if the perimeter of the triangle is less than 32

NARA [144]

9514 1404 393

Answer:

{4, 5, 6, 7, 8}

Step-by-step explanation:

The inequality related to the perimeter is ...

x +(x +4) +11 < 32

2x < 17 . . . . . . . . . . . . subtract 15

x < 8.5

The inequality related to the triangle inequality is ...

(x) +(x +4) > 11

2x > 7

x > 3.5

Then possible whole-number values of x are ...

{4, 5, 6, 7, 8}

How do i evaluate (7 to the power of 2)to the power of 3)=7 to the power of 5

kakasveta [241]

Step-by-step explanation:

$(7^2)^3=7^5\qquad\bold{FALSE}\\\\\text{because}\\\\7^2=7\cdot7\\\\(7^2)^3=(7\cdot7)^3=(7\cdot7)\cdot(7\cdot7)\cdot(7\cdot7)=\underbrace{7\cdot7\cdot7\cdot7\cdot7\cdot7}_6=7^6\\\\\text{or use}\ (a^n)^m=a^{nm}\\\\(7^2)^3=7^{2\cdot3}=7^6$
