An amateur soccer ball is priced at

Oduvanchick [21]

Answer: $26

Step-by-step explanation:

If $19.50 is 3/4, we need to find 4/4.

3/4 -> 0.75

4/4 -> 1

We will set up a proportion and solve.

$\frac{19.5}{0.75} =\frac{x}{1}$

19.5 = 0.75x

(PLEASEE HELPP 24 points)Regina’s work to find the surface area of a square pyramid from its net is shown below. A square pyrami

Fantom [35]

Answer:

She should have used One-half (9.4) (11.9) to represent the area of a single triangle

Step-by-step explanation:

The pyramid is composed by 4 triangles and 1 square

area of the square: base² = 9.4²

area of each triangle = 1/2*base*height = 1/2*9.4*11.9

surface area of the pyramid = 4*area of each triangle + area of the square = 4*(1/2*9.4*11.9) + 9.4²
