A shop sells compost in 20 litre bags and in 40 litre bags.
One day the shop had two special offers for the compost
20 litres 40 litres
2 bags for £3.50 3 bags for £9
which offer is the better value for the money?
Answer:
2
Step-by-step explanation:
3.50/2 = 1.75 and 9/3= 3
so 2 bags for £3.50 is better than 3 bags for £9
Write in slope intercept form of the equation of the line parallel to y= -2x + 5 and that passes through the point (3,1)
Answer:
y = -2x + 7
Step-by-step explanation:
In a equation thats parallel to y = -2x + 5, we have the same slope but different y intercepts (b).
SO we plug in point (3, 1) into y = mx + b
y = -2x + b
1 = -2(3) + b
1 + 6 = b
b = 7
So just plug in b back into the equation
y = mx + b
y = -2x + 7
Answer:
Step-by-step explanation:
y= -2x + 7
using point-slope formula:
y - y1 = m(x - x1)
Substitute:
y - 1 = m(x - 3)
Now, what is m and how do we find it?
m represents the slope. To find the slope in this circumstance, we have to look at the equation that we were given in the problem.
y= -2x + 5
Since we are trying to find a line parallel to this equation, we will be using the same slope that this uses.
The slope in the equation is -2.
Let’s substitute -2 for m.
y - 1 = -2(x - 3)
Now distribute:
y - 1 = -2x +6
Add 1 to both sides:
y = -2x + 7
Now we have an equation in slope-intercept form that is parallel to y= -2x + 5 and runs through the point (3, 1).
Solve: 3f + 1 < 2f -5
Please proof as well.
Answer:
f < -6
Step-by-step explanation:
3f + 1 < 2f - 5
Subtract 2f from both sides
f + 1 < - 5
Subtract 1 from both sides
f < -6
Answer:
f<-6
Step-by-step explanation:
3f<2f-6
f<6

Blas y Raul se han colocado en línea recta en lados opuestos de un generador eólico para medir su altura el terreno es llano y los dos amigos están separados por 41 m cada uno desde su posición mide el ángulo con el que se ve el generador desde el suelo qué altura tiene el generador
Answer:
La pregunta esta incompletea porque no incluye el angulo de Raul y el angulo de Blas. Busque un ejemplo similar y encontre que el angulo de Blas es 60° y el de Raul es 45°. Suponiendo que ambos midieron el angulo desde el suelo:
tangente 60° = altura / (41 - d)
tangente 45° = altura / d
altura = (41 - d) · tangente 60° = (41 - d) · 1.73205
altura = d · tangente 45° = d · 1
d = 71.01408 - 1.73205d
2.73205d = 71.01408
d = 71.01408 / 2.73205 = 25.993 ≈ 26 metros
sustituimos:
altura = d · tangente 45° = 26 · 1 = 26 metros
La altura del generador es de 26 metros
What is the greatest common factor of 120 and 168
Answer:
24
Step-by-step explanation:
gcf for that is 24 I think
Answer:
24
Step-by-step explanation:
120/24 = 5
168/24 = 7
5 and 7 do not have any common factors, hence they cannot be reducible.

What percent of 153 is 9.18? Show your work as well please
Answer:
6% of 153 is 9.18 and thats the answer
Answer:
9.18 is 6% of 153
Step-by-step explanation:
p/100 x 153 = 9.18
100/153 x p/100 x 153 = 100/153 x 9.18
100/153 x p/100 x 153 = 918/153
p=6

Answer:
2sqrt(14)*i
Step-by-step explanation:
(sqrt(-56))
since theres a negative in it we know there will be an i in the answer.
We need to find two numbers that multiple to 56 with at least one of them being a perfect sqaure
7*8 doesn't work
4*14 = 56
ok sqrt(4) = 2
can't take the sqaure of (14)
so we are left with
2sqrt(14)*i <---remember from before?
-3 1/6 divide by (-2 1/3)
Answer:
1 5/14
Step-by-step explanation:
-3 1/6 / -2 1/3
-3 1/6 = -19/6
-2 1/3 = -7/3
-19/6 / -7/3 = -19/6 x -3/7
-19 x -3 = 57
-6 x -7 = 42
57/42 = 1 5/14

Answer:
-101 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relevant relation is ...
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft
__
The usual relation between estimates and errors is ...
error = estimate - actual
Then ...
actual = estimate - error
For the given angle and error, the actual angle is ...
actual angle = 47° -(-1°) = 48°
actual height = (2640 ft)·tan(48°) ≈ 2932 ft
Then the change in the height of the mountain due to the error is ...
2831 ft -2932 ft = -101 ft
The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
