2 litres of lemonade costs £2.60. Find the cost of 6 litres of lemonade
Answer:
£7.80
Step-by-step explanation:
Since you multiply 2 by 3 to get 6, we are going to multiply 2.6 by 3
2.6 x 3 = 7.8
Thus the cost of 6 litres of lemonade is £7.80

You must find two different numbers on the number like. I will use (0, 1) and (4,0)
0-1/4-0
Combine
-1/4
m = -.25
y = 2x – 1
how do you graph this linear equation???
Answer:
You can choose x as any value like x = 7
if x were to equal 7 then
the equation would be y = 2 times 7 - 1
2 times 7 = 14 and 14-1 = 13
y would be 13 ifi x was 7
so you can graph the point 7,13

(16/25)-3/2 help me solve
Answer:
-43/50
(decimal) = -0.86
Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50
In 2019, the New England Patriots played 16 football games. The ratio of the number of games they won to the the number of games they lost was 3/1. How many games did they win? How many games did they lose?
Answer:
New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.
Step-by-step explanation:
The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose the number of games they won is W and the number of games they lost is L.
As per the given
Total games L + W = 16
Ratio W/L = 3/1
W = 3L
L + 3L = 16
4L = 16
L = 4
And, W = 3 x 4 = 12
Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".

.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)
Answer:
45 g de oxido de hierro (III) liberarán 18.9 L de CO₂
Step-by-step explanation:
La reaccion quimica es la siguiente:
Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)
1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.
Pasamos la masa de F₂O₃ a moles:
159.6 g . 1 mol /159.7g = 1 mol de oxido
Entonces, aplicamos la regla de tres:
1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.
Ahora calculamos los nuevos moles:
45g . 1 mol /159.7 g = 0.282 moles
Aplicamos la regla de tres:
Si un mol de oxido produce 3 moles de CO₂
0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂
Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:
Si 3 moles de CO₂ ocupan 67.2 litros
0.845 moles ocuparan (0.845 . 67.2/ 3 ) = 18.9 litros

Answer:
y = 1/2 x+4
Step-by-step explanation:
Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.
The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].
I'll be plugging in (2,5) and (4,6) to calculate the slope.
m = (6-5)/(4-2) = 1/2
The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.
Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4
The area of a circle is 36 pi M squared what is the circumference in meters express your answer in terms of pi
Answer:
Circumference = 12π m
Step-by-step explanation:
The area of the circle, A = 36π
We need to find the circumference of the circle.
The area of a circle is given by :
[tex]A=\pi r^2\\\\36\pi=\pi r^2\\\\r=6\ m[/tex]
The circumference of a circle is given by :
[tex]C=2\pi r\\\\C=2\pi \times 6\\\\C=12\pi\ m[/tex]
So, the circumference of the circle is 12π meters.
12 = 3(m - 17)
Help please. You have to use distributive property to solve.
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)

There are 9 teachers and 5 aides at the Hills Elementary School. What is the ratio of teachers to all adults?
Answer:
C. [tex]\frac{9}{14}[/tex] , 9:14 , or 9 to 14
Step-by-step explanation:
With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of [tex]\frac{9}{14}[/tex] , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.
