Reduce a ratio 3/4in: 3/16 ft
Answers
Answer:
4in : 1ft
Step-by-step explanation:
We start with:
3/4 in = 3/16 ft
This means that the length of 3/4 inches is the same as the length of 3/16 feet.
To reduce this, we can start by dividing by 3 in both sides of the equation:
(3/4)/3 in = (3/16)/3 ft
1/4 in = 1/16 ft
Now we can multiply both sides by 16:
16/4 in = 16/16ft
4 in = 1ft
now we reduced the ratio to:
4in : 1ft

Answer:
k = 100/9
Step-by-step explanation:
In this question, we will be solving for "k".
Solve:
9/10 = 10/k
Cross multiply.
(9 · k) = (10 · 10)
9k = 100
Divide both sides by 9
k = 100/9
Your answer would be k = 100/9

If y = 3x – 8, and y = f(x), find f(2). *
Answers
Answer:
f(2) = -2
Step-by-step explanation:
Replace y with f(x). The equation is now f(x) = 3x - 8. f(2) means that you replace all of the x’s with 2’s. Bringing the equation to f(2) = 3(2) - 8. You now just have to solve the equation. f(2) = 6 - 8. f(2) = -2
Annabelle is working two summer jobs, making $10 per hour babysitting and making $20 per hour lifeguarding. In a given week, she can work no more than 19 total hours and must earn no less than $290. If Annabelle worked 3 hours babysitting, determine the minimum number of whole hours lifeguarding that she must work to meet her requirements. If there are no possible solutions, submit an empty answer.
Answers
Answer:
she would need to work at least 13 hours lifeguarding to get to the 290 her with the of working an extra 3 hours
Step-by-step explanation:
subtract the 30 dollars from babysitting from the 290 needed you 260 then divide it by 20
The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Annabelle is working two summer jobs, making $10 per hour babysitting and making $20 per hour lifeguarding.
In a given week, she can work no more than 19 total hours and must earn no less than $290.
Now,
Let x represents the number of hour for babysitting, and 'y' represents the number of hours for lifeguarding.
Since, In a given week, she can work no more than 19 total hours and must earn no less than $290.
Hence, We can formulate;
⇒ x + y < 19
And, 10x + 20y > 290
So, For Annabelle worked 3 hours babysitting, the minimum number of whole hours lifeguarding is,
⇒ 3 + y < 19
⇒ y < 16
And, 10x + 20y > 290
⇒ 30 + 20y > 290
⇒20y > 290 - 30
⇒ 20y > 260
⇒ y > 13
Thus, The possible value of y = 14, 15
So, The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.

which statement describes the solutions of the equation? 4x/3x+1 = x/2x+10
A) the equation has one valid solution and no extraneous of solutions.
B. the equation has one valid solution and one extraneous of solutions.
C. the equation has two valid solution and no extraneous of solutions.
D. the equation has no valid solution and two extraneous of solutions.
Answers
Answer:
The equation has one valid solution and no extraneous of solutions.Step-by-step explanation:
Given the expression;
4x/3x+1 = x/2x+10
We are to get the nature of the value of x
Cross multiply;
x(3x+1) = 4x(2x+10)
3x²+x = 8x²+40x
Collect like terms;
3x²-8x² + x - 40x = 0
-5x²+x -40x = 0
-5x²-39x = 0
-5x² = 39x
-5x = 39
x = -39/5
Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.
The equation has one valid solution and no extraneous of solutions. The correct option is A.
What is equation?An equation is a mathematical expression in terms of one or more unknown variable.
Given the equation : 4x/3x+1 = x/2x+10
Simplify by Cross multiplication, we get
x(3x+1) = 4x(2x+10)
3x²+x = 8x²+40x
3x²-8x² + x - 40x = 0
-5x²+x -40x = 0
-5x²-39x = 0
Simplifying further and solving for x
-5x² = 39x
-5x = 39
x = -39/5
We have just one value of x.
Hence, the equation has one valid solution and no extraneous of solutions.
