Explanation: 6.50 - 0.65 = 5.85 and 1.95 times 3 is 5.85 so she spends the rest of her money on 3 pounds of tomatoes.
Given the preimage points: find the coordinates
of the dilated image using the scale factors. *look at picture*
Question 1)
Answer:
Please see the explanation.
Step-by-step explanation:
We know that the dilation of an original object shows how much bigger or smaller the image will really get, as compared to the original shape.
Also,
if the value of scale factor > 1, the image will get bigger.if the value of scale factor < 1, the image will get smaller.The new coordinates of the image can be determined by multiplying the scale factor with the coordinates of the original object.
Given the preimage points:
A(0, 5)B(4, 9)C(-1, -8)The formula of the dilation by a scale factor of 3:
(x, y) → (3x, 3y)
As the scale factor > 1, so the image will be bigger.Therefore, the coordinates of the dilated image after the dilation by a scale factor of 3 will be:
A(x, y) → (3x, 3y) = A(0, 5) → (3(0), 3(5)) = A'(0, 15)
B(x, y) → (3x, 3y) = B(4, 9) → (3(4), 3(9)) = B'(12, 27)
C(x, y) → (3x, 3y) = C(-1, -8) → (3(-1), 3(-8)) = C'(-3, -24)
Question 2)
Answer:
Please see the explanation.
Step-by-step explanation:
Given the preimage points:
A(0, 5)B(4, 9)C(-1, -8)The formula of the dilation by a scale factor of 1/2:
(x, y) → (1/2x, 1/2y)
As the scale factor < 1, so the image will be smaller.Therefore, the coordinates of the dilated image after the dilation by a scale factor of 1/2 will be:
A(x, y) → (3x, 3y) = A(0, 5) → (1/2(0), 1/2(5)) = A'(0, 5/2)
B(x, y) → (3x, 3y) = B(4, 9) → (1/2(4), 1/2(9)) = B'(2, 9/2)
C(x, y) → (3x, 3y) = C(-1, -8) → (1/2(-1), 1/2(-8)) = C'(-1/2, -4)

Sara sold hotdogs and drinks at the soccer game.
18 hot dogs and 9 drinks sold for $45.00
20 hot dogs and 12 drinks sold for $52.00
What is the charge for an order of 4 hot dogs and 3 drinks?
Answer:
$11
Step-by-step explanation:
Set up the system of equations
18x + 9y = 45
20x + 12y = 52
Let's try to get y on one side for the first equation.
9y=45-18x
y=5-2x
Now substitute it into the second equation.
20x + 12(5-2x) = 52
20x + 60 - 24x = 52
-4x = -8
x = 2
Now solve for y using the first equation.
18(2) + 9y = 45
36 + 9y = 45
9y = 9
y = 1
Now that we know x and y we can solve for the price of 4 hot dogs and 3 drinks.
4(2) + 3(1) = z
8 + 3 = z
11 = z
That means that the price is 11 dollars.

si se colocaron 16 postes para sostener 385.5m de cable telefonico, ? que distancia hay entre 2 postes?
Responder:
Los 48.1875m
Explicación paso a paso:
Si se colocaron 16 postes para soportar 385,5 m de cable telefónico, esto significa que la distancia entre los 16 postes es de 385,5 m.
Debemos encontrar la distancia entre 2 postes;
16 puestos = 385,5 m
2 puestos = x
Cruz multiplicar
16 veces = 2 * 385,5
16x = 771
x = 771/16
x = 48,1875 m
Por lo tanto, la distancia entre 2 postes es de 48,1875 m.
