Answer:

  y = 4.625

Step-by-step explanation:

Subtract 16.4 from both sides and collect terms.

  8.4 -6.8 -16.4 = -3.2y +16.4 -16.4

  -14.8 = -3.2y

Divide both sides by -3.2.

  -14.8/-3.2 = (-3.2y)/-3.2

  4.625 = y

The solution is y = 4.625.

A 5-foot ladder is leaning against a 4-foot wall. How far must the bottom of the ladder be from the base of the wall so that the
frutty [35]
Using the pythagorean theroem to solve this problem (a squared plus b squared equals c squared)
C would be the hypotenuse, which in this case is the five ft ladder.
The other known length of the leg is 4 ft.
5^2-4^2=25-16=9
9 must equal a^2 and a must equal 3
The correct answer is 3 ft

The area of the figure is 112 square inches.

Step-by-step explanation:

Step 1:

To calculate the value of the composite shape we first divide it into shapes that we know.

In this case, the composite shape consists of a rectangle and a parallelogram attached to it.

If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.

Step 2:

The rectangle has a length of 22 cm and a width of 8.5 cm. The area of a rectangle is the product of its length and its width.

The area of the rectangle= (length)(width)= (22)(8.5)=187.

The area of the rectangle is 187 square cm.

Step 3:

The area of a parallelogram is the product of its base length and its height. The given parallelogram has a base length of 22 cm and a height of 7.5 cm.

The area of the parallelogram = (baselength)(height) = (22)(7.5) = 165.

The area of the parallelogram is 165 square cm.

Step 4:

Now we calculate the area of the entire figure by adding the areas of the rectangle and the parallelogram.

Area of the figure = 187 + 165 = 352.

So the area of the figure is 352 square cm.
