Answer:
x=5
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
If x varies directly with y, a ratio can be used to find the new x value. The ratio will look like this [tex]\frac{27}{6}=\frac{x}{2}[/tex]. In order to solve this ratio, cross multiply to get 6x=54. Now, this can be solved by dividing both sides of the equation by 6 in order to get the answer that x=9

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!

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
Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself. A. Find the solution to the equation you chose for the story above. B. Explain what the solution means in the context of the story.
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.

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! :)

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.

Explain how 32
Divided 4 can help you solve
320 divided 4?
Answer/Step-by-step explanation:
Since 320 is 10 times 32. The answer for 320 divided by 4 is going to be 10 times the answer of 32 divided by 4.
320 ÷ 4 = 80
32 ÷ 4 = 8
As 320 is 10 times of 32 then values results also 10 times.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
Given:
We have to divide 32 by 4.
The division is as follow:
= 32/4
= (4 x 8)/ 4
= 8
If we multiply 10 to 32 then we get 320.
Then, if we multiply 10 to 8 we get
= 10 x 8
= 80
