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.
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)

3.∠P=∠Q 3. corresponding angle of triangle are
equal
proved
i need help to answer please
Answer:
m∠N = 41°
Step-by-step explanation:
Here,
In △MNO, m∠M = (6x + 1°) ...(1)
m∠N = (3x - 10°) ...(2)
m∠0 = (x + 19°) ...(3)
Here, We know that the sum of all angles of a triangle is 180°
Then,
(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
6x + 1° + 3x - 10° + x + 19° = 180°
6x + 3x + x + 1° - 10° + 19° = 180°
10x + 10° = 180°
10x = 180° - 10°
10x = 170°
x = 170° ÷ 10°
x = 17°
Now, put the value of x in (1), (2) and (3)
m∠M = (6x + 1°)
= (6(17) + 1°)
= (102° + 1°)
m∠M = 103°
m∠N = (3x - 10°)
= (3(17) - 10°)
= (51° - 10°)
m∠N = 41°
m∠0 = (x + 19°)
= (17 + 19°)
m∠0 = 36°
Thus, The m∠N = 41°
FOR VERIFICATION ONLY:(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
(6(17) + 1°) + (3(17) - 10°) + (17 + 19°) = 180°
103° + 41° + 36° = 180°
180° = 180°
Hence, L.H.S = R.H.S

Ian wants to run 4 1/2 miles to get ready for his upcoming race. He has set up 3 markers the same distance apart to show how far he has run. How far apart are the markers?
Answer:
1 1/2
Step-by-step explanation:
Given that:
Total miles to run = 4 1/2 miles
Number of same distance markers set = 3
The diatances between each marker :
Total distance / number of markers
4 1/2 ÷ 3
9 /2 ÷ 3
9 / 2 * 1 /3
= 9 /6
= 3/2 = 1 1/2
Hence, the distance between each marker = 1 1/2

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.

Van purchased a DVD player on sale. The original selling price was $154.30. The sale price was $132.17. What is the first step in finding the percent markdown? Find the percent markdown.
Answer:
Percentage decrease= 14.34%
Step-by-step explanation:
Giving the following information:
The original selling price was $154.30. The sale price was $132.17.
To calculate the percentage decrease, we need to use the following formula:
Percentage decrease= [(P0 - P1)/P0]*100
Percentage decrease= [(154.3- 132.17)/154.3]*100
Percentage decrease= 14.34%

A girl had $6.50 while shopping at a local store. She bought 1 lb. of potatoes for $0.65 and wanted to spend the rest on tomatoes. Each pound of tomatoes costs $1.95. Which inequality models the pounds (n) of tomatoes she could buy?
Answer: 6.50-.65 > 1.95x
Step-by-step explanation:
Answer: 3 Ib
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.

write and equation in slope intercept form (y=mx+b) for the graph below
Answer:
y=1/3x+0 or y=1/3x
Step-by-step explanation:
find the slope by taking two points and putting them in
y2 - y1/x2 - x1
so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3
then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)
y - 2 = 1/3(x-6)
when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given
