What is the greatest value 20g of flour 3 for 3.50 or 40g of flour for 2 for 9£ which is better for money
Answer:
It is better to buy 20 g of flour 3 for 3.50
Step-by-step explanation:
It is given that 20g of 3 for 3.50
It means 3 packets of 20 g is 3*20 =60
So, 60g is for 3.50
So, 1 g =[tex]\frac{3.5}{60}[/tex]=0.05833 per gram.
Now, let's find unit rate for 40 g of 2 for 9.
2 packets of 40 gram = 2* 40 =80 grams
So, 80 grams costs 9
So, 1 gram =[tex]\frac{9}{80}[/tex] =0.1125
So, it is better to buy 20 g of flour 3 for 3.50

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}

Write 65/22 as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.
Answer:
2.954545454
Step-by-step explanation:
65/22 = 65 divided by 22. That is how many times 22 can go into 65
A decimal number has a decimal point in it. That is a whole number and some fraction that could be in tenths or otherwise.
65 is the numerator,
22 is the denominator
Using a calculator
65/22 = 2.9545454

Answer:
These are confusing Beth , b/c you have to remember that they will add to 100%
Step-by-step explanation:
so
green = 3* yellow
100% = green + yellow + 35% + 25%
100% = 3* yellow + yellow +60%
40% = 4* yellow
10% = yellow
30% = green
there are 14 purples in the bag , which is 35% of total
14/.35 = 40
there are a total of 40 pins
so
4 are yellow (10% of 40 or 40* 0.1)
12 are green (30% of 40 or 40*0.3)
14 are purple (35% of 40 or 40*0.35)
10 are grey (25% of 40 or 40*0.25 )
see? : |

1. Employees of a landscaping company built a retaining wall with area 23(3/8) sq ft. They used brick to make the top portion of the wall, which is 8(1/2) feet. What is the total height of the wall? Write an equation to represent the situation. Then solve. Part 2: If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Answer:
a. h = A/w = 2 ³/₄ ft
b. A'/A = 2/3
Step-by-step explanation:
a. What is the total height of the wall? Write an equation to represent the situation. Then solve.
The wall is a rectangle and its area is A = wh where w = width and h = height of wall.
Making h subject of the formula,
h = A/w
Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then
h = A/w
= 23 ³/₈ ft² ÷ 8 ¹/₂ ft
= 187/8 ft² ÷ 17/2 ft
= 187/8 ft² × 2/17 ft
= 187/4 ft² × 1/17 ft
= 187/68 ft
= 2 ³/₄ ft
b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft² and the total are of the retaining wall is A = 23 ³/₈ ft²
The fraction of the wall that is brick = A'/A
= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²
= 187/12 ÷ 187/8
= 187/12 × 8/187
= 8/12
= 2/3
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

Answer:
I think c, - 1.8 is the answer
-1.6 (c)
My reasoning behind this is that the number would be logical considering the fact that the point is close to 0. Also, I ruled out the other choices, and here's how I did it:
I know that A is not the answer because that would make it farther back on the number line and the point B is closer to 0 than it is to 3.8 so, I know that A is not correct.
I know that B is not the answer because -5.23 would be farther behind point A which rules it out entirely.
I know that D is not the answer because 0.1 would be right after point c (0) meaning that the point can be ruled out right away.
That leaves the only logical answer to be C because it is closer to 0 but still in between points A and B.
Hope this helps and have a nice day.

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 2 mg.
What was the initial mass (in mg) of the sample?
What is the mass 5 weeks after the start?
Answer:
The initial mass of the sample was 16 mg.
The mass after 5 weeks will be about 0.0372 mg.
Step-by-step explanation:
We can write an exponential function to model the situation.
Let the initial amount be A. The standard exponential function is given by:
[tex]P(t)=A(r)^t[/tex]
Where r is the rate of growth/decay.
Since the half-life of Palladium-100 is four days, r = 1/2. We will also substitute t/4 for t to to represent one cycle every four days. Therefore:
[tex]\displaystyle P(t)=A\Big(\frac{1}{2}\Big)^{t/4}[/tex]
After 12 days, a sample of Palladium-100 has been reduced to a mass of two milligrams.
Therefore, when x = 12, P(x) = 2. By substitution:
[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^{12/4}[/tex]
Solve for A. Simplify:
[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^3[/tex]
Simplify:
[tex]\displaystyle 2=A\Big(\frac{1}{8}\Big)[/tex]
Thus, the initial mass of the sample was:
[tex]A=16\text{ mg}[/tex]
5 weeks is equivalent to 35 days. Therefore, we can find P(35):
[tex]\displaystyle P(35)=16\Big(\frac{1}{2}\Big)^{35/4}\approx0.0372\text{ mg}[/tex]
About 0.0372 mg will be left of the original 16 mg sample after 5 weeks.
