Answer:

Option D.

Step-by-step explanation:

Northlake high school has two lunch periods. Students can eat their lunch in the cafeteria or on an outside patio.

Percentage of students who have first lunch eat outside= $\frac{\text{Eat outside}}{\text{Total of first lunch}}$ = $\frac{(.17)(100)}{.55}=31$ %

Similarly percentage of second lunch students eat outside= $\frac{\text{Eat outside}}{\text{Total of second lunch}}$ = $\frac{(0.21)(100)}{(0.45)}=47$ %

Therefore, option D is the correct option.

Find the value of x in the equation 3(2x-4)-5(x-2)=1

Lyrx [107]

Answer:

x=3

Step-by-step explanation:

3(2x−4)−5(x−2)=1

Step 1: Simplify both sides of the equation.

3(2x−4)−5(x−2)=1

(3)(2x)+(3)(−4)+(−5)(x)+(−5)(−2)=1(Distribute)

6x+−12+−5x+10=1

(6x+−5x)+(−12+10)=1(Combine Like Terms)

x+−2=1

x−2=1

Step 2: Add 2 to both sides.

x−2+2=1+2

x=3

Helpppppppppppppp please

Bingel [31]

Answer:29

so the mini triangle in the corner is a mini model of the entire triangle, all you have to do is take the width or bottom number and find the factor in which it is smaller, then take the height of the smaller triangle and add the factor in which it increases to it. so the factor goes up by 31 1/2--9=22 1/2 and adding the factor in which it increases to the height is 22 1/2+6 1/2=29 because 2 halfs make a whole.

What is the image of the point (3,2)(3,2) after a rotation of 90^{\circ}90 ∘ counterclockwise about the origin?

BARSIC [14]

Answer: = (-2,3)

Step-by-step explanation:

Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.

Here, fixed point = origin = (0,0)

Transformation rule for rotation of $90^{\circ}$ counterclockwise about the origin:

$(x,y)\to (-y,x)$

Then, the image of the point (3,2) = (-2,3)

Hence, the image of the point (3,2) after a rotation of $90^{\circ}$ counterclockwise about the origin = (-2,3)
