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

ratio to 54 seconds to 2 minutes
Answer:
54/120
Step-by-step explanation:
Ratio to 54 seconds to 2 minutes is 9 : 20
Ratio Analyses:Find:
Ratio to 54 seconds to 2 minutes
Computation:
We know that,
1 minutes = 60 second
So,
2 minutes = 120 second
Ratio to 54 seconds to 2 minutes = 54 / 120
Ratio to 54 seconds to 2 minutes = 27 / 60
Ratio to 54 seconds to 2 minutes = 9 : 20

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.
Combine like terms. 3x − 2y + 4z – x + 5y + 3x - 2y + 4z – x + 5y + z
3x-2y+4z-x+5y+3x-2y+4z-x+z
First, reorder(I put the like terms in parenthesis to help you see the work better).
(3x+3x-x-x)+(5y-2y-2y)+(4z+4z+z)
Now, we add/subtract like terms.
(6x-2x)+(5y-4y)+(8z+z)
Lastly, we combine.
4x+y+9z

Please Help me and i wil......i dunno just help
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.

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 )

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

. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side of length 8.
Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:
[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]
Let a=8, b=7 and c=14, then by using Law of Cosine, we get
[tex]\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}[/tex]
[tex]\cos A=\dfrac{49+196-64}{196}[/tex]
[tex]\cos A=\dfrac{181}{196}[/tex]
Taking cos inverse on both sides.
[tex]A=\cos^{-1}\dfrac{181}{196}[/tex]
[tex]A=22.561328[/tex]
[tex]A\approx 22.6[/tex]
Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
