erik [133]

Answer: 44

Step-by-step explanation:The way to calculate the number of coins that she had originally is to look at the difference in coins that changed hands. She sold 12 coins, but only bought 7 new ones. 12-7=5. Lucinda now has 5 coins less than what she started out with. So, she has 39 now, and then add 5 and the answer is 44 coins.

Square perimeter= 20 triangle base= 3 and height =3.5 find the percentage of the area inside the square shaded
Lisa [10]

Answer:

Area of geometric figures mentioned calculated.

Step-by-step explanation:

Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5

Area of square = ( Side )^2 = ( 5 )^2 = 25

Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25

I dont know what to do lol
atroni [7]

Answer:

15 units

Step-by-step explanation:

The distance between two points can be found using the following formula:

d\sf=\sqrt{(x_2-x_1)+(y_2-y_1)}

Given points:

(-7, 5) and (2, -7)

<u>where:</u>

  • x₁ = -7
  • x₂ = 2
  • y₁ = 5
  • y₂ = -7

Substitute these points into the formula and simplify:

\sf d=\sqrt{(2-(-7))^2+((-7)-5)^2} \ \textsf{[simplify the radicand]}\\\\ d=\sqrt{(2+7)^2+(-12)^2} \ \textsf{[simplify]}\\\\d=\sqrt{(9)^2+(-12)^2} \ \textsf{[evaluate the power]}\\\\d=\sqrt{81+144} \ \textsf{[add]}\\\\d=\sqrt{225}\ \textsf{[simplify]}\\\\d=15

The distance between the two points is 15 units.
