Answer:
A. 1/12+5/12+5/12
Step-by-step explanation:
From the given options; let us calculate the fractions and see which one tallies with 11/12
a) [tex]\dfrac{1}{12}+ \dfrac{5}{12} + \dfrac{5}{12}[/tex]
The lowest common multiple (L.C.M) here is 12 because 12 goes in all the denominators.
So;
[tex]= \dfrac{1+5+5}{12}[/tex]
[tex]= \dfrac{11}{12}[/tex]
b)
[tex]\dfrac{5}{4}+\dfrac{3}{4}+\dfrac{3}{4}[/tex]
Here, the lowest number that can be divisible by the denominators is 4
[tex]=\dfrac{5+3+3}{4}[/tex]
[tex]=\dfrac{11}{4}[/tex]
c)
[tex]\dfrac{5}{6}+\dfrac{6}{6}[/tex]
[tex]=\dfrac{5+6}{6}[/tex]
[tex]=\dfrac{11}{6}[/tex]
d)
[tex]\dfrac{10}{12}+\dfrac{2}{12}[/tex]
[tex]=\dfrac{10+2}{12}[/tex]
[tex]= \dfrac{12}{12}[/tex]
= 1
Thus, from the given options, the expression that has the sum of 11/12 is option A.
Hi can you help please
Answer:
x ≤ -4
Step-by-step explanation:
The dot/filled-in circle is on -4, so that's where we get that part of the inequalityThe line is going to the left of -4 (going towards the negatives), so x is less than -4The dot/circle is filled in, which means it is an "or equal to" symbol (in our case it's less than or equal to)Put it all together: x ≤ -4I hope this helps!

Answer:
12.5 pie , 39.25 using pie=3.14, and 39.28 to be exact
Step-by-step explanation:
BTW n=pie
10in= Diameter
5in=Radius
Area=n5^2
= 25n/2
=12.5n
12.5 times 3.14= 39.25

Answer:
12.8
Step-by-step explanation:
Tan 52° = x/10
x = Tan 52° * 10
x = 1.2799 × 10
x = 12.799
Rounding to the nearest tenth, we have
x = 12.8
Answer:
Step-by-step explanation:
Let's use 52 as our degree.
The adjacent side to 52 is x, and the opposite is 10.
Since it's gonna be opposite over adjacent, we need to use the Tangent ratio.
(tan)
Now let's start our calculations.
Tan52 = x/10
(Tan52)(10) = x
x = 12.79941532
Let's round that to the nearest tenth place.
x = 12.8 units
(Don't forget the degree sign for 52 in Tan52!!!)
Hope that helped! :)
Which expression is equivalent to
-4(h - 2) + 20
a. -4h + 12
b. -4h + 18
c. -4h + 28
d. -4h + 22
Answer:
C.
Step-by-step explanation:
it would simplify to -4h+8+20
then if you gather like terms it would be -4h+28

William fills 1/3 of a water bottle in 1/15 of a minute. How much time will it take him to fill the bottle?
Answer:
1/5 minutes
Step-by-step explanation:
✓Let the X= a bottle of water
✓Let y= number of minutes it will takes to fill a bottle
We can express the given statement as
1/3 X = 1/15 mins
X= ymins
If we cross multiply the two expression above we have
X/15 mins= X/3 mins * ymins
15 mins * X * y mins= 3X
Divide both sides by X
15 mins * y= 3
Make "y" the subject of the formula
y= 3/15 mins
Divide both numerator and denominator by factor of 3.
y= 1/5 minutes
Hence, the time it will take him to fill the bottle is 1/5 minutes
Find the value of the variables.

Element X is a radioactive isotope such that every 27 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 7900 grams, how much of the element would remain after 12 years, to the nearest whole number?
Answer:
About 5, 805 grams remaining.
Step-by-step explanation:
We are given that every 27 years, the mass of Element X decreases by half.
We can write an exponential function to model the situation. The standard exponential function is given by:
[tex]\displaystyle f(t)=a(r)^t[/tex]
Where a is the initial amount, r is the rate, and t is the time, in this case years.
Since it is halved, our rate r is 1/2.
Since it is halved for every 27 years, for t, it will be t/27.
Therefore, our function is:
[tex]\displaystyle f(t)=a\Big(\frac{1}{2}\Big)^{t/27}[/tex]
Our initial sample is 7,900 grams. Hence, a = 7900:
[tex]\displaystyle f(t)=7900\Big(\frac{1}{2}\Big)^{t/27}[/tex]
We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:
[tex]\displaystyle f(12)=7900\Big(\frac{1}{2}\Big)^{12/27}\approx5805\text{ grams}[/tex]
After 12 years, there will be about 5805 grams remaining.
Answer:
About 5, 805 grams remaining.
Step-by-step explanation:
We are given that every 27 years, the mass of Element X decreases by half.
We can write an exponential function to model the situation. The standard exponential function is given by:
→ f(t)=a(r)^t
Where a is the initial amount, r is the rate, and t is the time, in this case years.
Since it is halved, our rate r is 1/2.
Since it is halved for every 27 years, for t, it will be t/27.
Therefore, our function is:
→ f(t)=a(1/2)^t/27
Our initial sample is 7,900 grams. Hence, a = 7900:
→ f(t)=7900(1/2)^t/27
We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:
→ f(12)=7900(1/2)^12/27 ≈5805 grams
After 12 years, there will be about 5805 grams remaining.

Answer:
3x + 6 =27
Step-by-step explanation:
A. The solution is 7! First I Subtracted 6 from both sides of the equation, Then I Divided both sides of the equation by the same term. Then I got "7" from doing the following.
B. The solution is the x in the answer which is the amount of juice he poured.

2. Last year Kellog decided to reduce the size of packaging in order to raise 1 p the price per ounce. If the original size of the box was 18 oz and Kellog reduced the size of the packaging by 15%. How many oz can the new box hold?
Answer:
15.3 oz
Step-by-step explanation:
Here, we want to get the value of the new size after reduction
We start with reduction amount
That will be;
15/100 * 18 = 2.7 oz
So we now get what it can hold
That’s;
18-2.7 = 15.3 oz
