So first you would substitute j and k in the expression.

7(0.5)+5-8(0.25)

3.5+5-2

It would equal 6.5

Hope this helps!

Find the area of the figure below by first finding the areas of the rectangle and triangles.
masha68 [24]

a. The area of the rectangle: 16 units²

b. The area of the triangle on the left: 6 units²

c. Area of the triangle on the right: 10 units²

d. Area of the figure: 32 units²

<h3>What is the Area of a Rectangle and a Triangle?</h3>
  • Area of a rectangle = (l)(w)
  • Area of a triangle = 1/2bh

a. l = 4 units

w = 4 units

Area of the rectangle = (4)(4) = 16 units²

b. b = 3 units

h = 4 units

Area of the triangle on the left = 1/2(3)(4) = 6 units²

c. b = 5 units

h = 4 units

Area of the triangle on the right = 1/2(5)(4) = 10 units²

d. Area of the figure = 16 + 6 + 10 = 32 units²

Answer=15:39

Step1(find the number of right handed batters)

Left-handed batters=45

 5    45
__=___
8      x


Cross multiply
5x=360
divide both sides by 5
x=72
Right-handed batters=72

Step 2 (find the number of total batters)
total batters=45+72=117

Step3 (find the ratio of left handed batters to total batters)

Left-handed batters to total batters= 45/117
45/117 can be shortened to 15/39

Answer=15:39
