Answer:

2√5

Step-by-step explanation:

(1/2) √80

Figure out the biggest number that can be squared by 80 in this case it's 16

(1/2) √(16 x 5)

since the square root of 16 is 4 put the 4 on the outside and leave 5 in since it can't be squared.

(1/2) 4√5

multiply (1/2) by 4 which equals 2

2√5

What is the y-coordinate of the midpoint of WU? A 2.5 B. -1.5 C. -0.5 D. 1.5

lilavasa [31]

Option C: -0.5 is the right answer

Step-by-step explanation:

Given is the graph on which different points are indicated.

We have to find the y-coordinae of the mid-point of WU.

The formula for mid-point is:

$(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

So we only have to know the y-coordinates of both points to find the mid-points y coordinate

So by observing the graph we get

y_1 =0

y_2 = -1

So,

$\frac{0-1}{2}\\= \frac{-1}{2}\\= -0.5$

Hence,

Option C: -0.5 is the right answer

The ratio of three angle are 3:4:5 what is the highest angle of the triangle??

SCORPION-xisa [38]

The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180

12x=180
x=180/12
x=15

The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: the highest angle would measure 75º.

Rosa thinks of a number. She rounds it to the nearest thousand and gets 35,000. When rounded to the nearest hundred, the rounded

ANEK [815]

Hey there! The answer will be below

B is the correct answer

Because in B the last 3 numbers are 500 (estimate) so 34,500 would be rounded to 35,000.Plus B makes the most sense.

Hope that helps!

You need to turn 1/2 to .5 and 3/4 to .75 then you use this equation.
75% * 950,000 (profit)
+ 25% * -285,000 (loss)
= then you subtract the numbers from the separate 
= answer --> expected profit from the second mall
