Rina8888 [55]

Answer: She will need about 15 bananas to feed 250 people that will be at the reunion.

Step-by-step explanation:

Let be "x" the number of bananas Stewart will need to feed 250 people that will be at the reunion.

According to the infomation provided in the exercise, we know that she needs 1.5 bananas per dish of pudding and one dish of pudding can feed 25 people.

Knowing this, we can set up the following proportion:

$\frac{1.5}{25}=\frac{x}{250}$

Finally, we must solve for "x":

$(250)(\frac{1.5}{25})=x\\\\x=15$

Therefore, she will need about 15 bananas to feed 250 people that will be at the reunion.

The vertices of a triangle are, A (2, 5) B (1, 2) C (3, 1),. Find the coordinates of the image after a

chubhunter [2.5K]

Answer:

The images are;

A’ (5,2) B’ (2,1) and C’ (1,3)

Step-by-step explanation:

Firstly, we want to reflect across the x-axis

When we reflect a point (x,y) over x-axis, we get (x,-y)

So;

A ( 2,5) becomes (2,-5)

B (1,2) becomes (1,-2)

C ( 3,1) becomes (3,-1)

Then we proceed to rotate 90 degrees counterclockwise about the origin

Here we have;

(x,y) becomes (-y,x)

(2,-5) becomes (5,2)

(1,-2) becomes (2,1)

(3,-1) becomes (1,3)
