Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
cricket20 [7]

Answer:

186 cm²

Step-by-step explanation:

<em>*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.</em>

<em>*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.</em>

<u>Left rectangle:</u>

A = lh

A = 12 (8)

A = 96 cm²

<u>Right rectangle:</u>

A = lh

A = 10 (9)

A = 90 cm²

<u>Total:</u>

A = 90 + 96

A = 186 cm²

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?
natta225 [31]
P(A | B) = \frac{P(A \cap B)}{P(B)}


P(A|B) = \frac{5/7}{7/8}


P(A|B) = \frac{5}{7} \div \frac{7}{8}


P(A|B) = \frac{5}{7}\times\frac{8}{7}


P(A|B) = \frac{5*8}{7*7}


P(A|B) = \frac{40}{49}
