maks197457 [2]

Answer:

$a=0$

Step-by-step explanation:

The given expression is;

$(\frac{1}{7})^{3a+3} =343^{a-1}$

This implies that;

$7^{-1(3a+3)} =7^{3(a-1)}$

Equate the exponents;

$-1(3a+3) =3(a-1)$

Expand;

$-3a-3 =3a-3$

$-3a-3a =-3+3$

$-6a=0$

$a=0$

The triangular pyramid shown is made up of four congruent triangles. The length of the base is 8 inches, and the height of the b

Aneli [31]

Answer:

(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))

Step-by-step explanation:

Base of the Pyramid = 8 Inches

Height of the Triangular Face = 6.9 Inches

In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.

Since the four triangles are congruent:

Lateral Surface Area = 4 X Area of One Triangle

Area of a Triangle = $\frac{1}{2}$ X Base X Height$

Area of one Triangular Face $= \dfrac{1}{2}(8)(6.9)$

Therefore:

Lateral Surface Area $= 4\left(\dfrac{1}{2}(8)(6.9)\right)$

Therefore, Talia is correct.

Rogers steps include a scale holding five bricks of equal weight. The scale reads 300 pounds. Write an equation relating Rogers

natta225 [31]

Answer:

R + 5b = 300

Step-by-step explanation:

Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.

We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.

We have been told to use R for Rogers weight and b for the weight of a single brick.

Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.

The sum of Rogers weight and the five bricks is equal to 300 pounds.

Therefore, the equation relating them is:

R + 5b = 300
