Answer:

C

Step-by-step explanation:

We can calculate the area of triangles ABD and DBC, and then add them together to get the area of the whole quadrilateral.

A =  \frac{11 \times 3 + 7 \times 9}{2}  =  \frac{33  + 63}{2}  =  \frac{96}{2}  = 48

After midnight, the cost of any taxi journey increased by 45% one journey cost $84.10 after midnight calculate the cost of the s
ArbitrLikvidat [17]

Answer:

$121.95

Step-by-step explanation:

First, we need to change 45% into a decimal. To do that, move the decimal point two spaces back, and we will have 0.45.

Multiply that by the original price $84.10

$84.10 x 0.45 = 37.845

Then add 84.10 with 37.845

This adds up to $121.945, which you can round to $121.95

The correct expression for a number which is 9 times as big as the number obtained after p has been increased
defon

Answer:

9(p + 4)

Step-by-step explanation:

One of the unknown variable is p.

First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).

Translating the word problem into an algebraic expression, we have;

9 * (p + 4) = 9(p + 4)

Simplifying further, we have;

9p + 36
