Use the correct order of operations to evaluate the following expression:(5+4).5+3.3

Mathematics
1 answer:
horsena [70]3 years ago

Answer:

For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).

Step-by-step explanation:

(5+4) × 5 + 3.3

Bracket open = 9

Since there is no division, so multiply 9×5, which is 45

Then add, 45+3.3

Answer= 48.3

Find the length of side Y (this is from the geometry for enjoyment and challenge textbook) PLEASE ANSWER ASAP IT'S DUE TOMORROW!
Ymorist [56]

Answer:

y= 3

Step-by-step explanation:

The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.

First, find the length of the side that both triangles are connected to.

tan30=x/9

Isolate the x variable and solve.

9(tan30)=x

x= 5.19615

Now use the Pythagorean Theorem to solve for the side length, y.

a^2+ b^2 = c^2

(5.19615)^2+ b^2= 6^2

c= 3

what is the midpoint of the segment joining the points (4,-2)and (-8,6) please show in steps how you got it
sashaice [31]
The x-coordinate of the midpoint will be the average of the two given x-coordinates, and the y-coordinate will be the average of the two given y-coordinates.
This can be written as
midpoint = ( \frac{x1+x2}{2} , \frac{y1+y2}{2}),
where the given points are (x1, y1) and x2, y2).

In the problem, you have (4, -2) and (-8, 6).
The midpoint will be
( \frac{4-8}{2} ,  \frac{-2+6}{2})=( -2, 2)
