If three out of the five are red and there are a total of 30 puzzle pieces then the number of black puzzle pieces will be 12.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
it is given that there are a total of 30 puzzle pieces three out of 5 are red, and the remaining are black.
From the given condition,
(3/5) of total puzzle pieces = Number of red puzzle pieces
(3/5) × 30 = Number of red puzzle pieces
Number of red puzzle pieces = 18
Total puzzle pieces = Red puzzle pieces + Black puzzle pieces
30 = 18 + Black puzzle pieces
Black puzzle pieces = 30-18
Black puzzle pieces =12
Thus, if three out of the five are red and there are a total of 30 puzzle pieces then the number of black puzzle pieces will be 12.

[tex]2 {}^{2x} = y[/tex]
now,

Mr. Webster is buying carpet for an exercise room in his basement. The room will have an area of 230 square feet. The width of the room with have 12&1/2 feet. What is the length?
PLEASE DO NOT JUST GIVE THE ANSWER, (I could have done that myself) PLEASE SHOW WORK ON HOW YOU GOT THE ANSWER.
Thanks!
Answer: 18.4 ft
Step-by-step explanation:
Area= L x W
230= 12.5 x L (Divide both sides by 12.5 to get L)
L= 18.4 ft
Answer:
The length of the room is 18 2/5 feet.
Step-by-step explanation:
The formula for finding the area of rectangles is A = l · w
Since the area and width is given to you, we can substitute that in the formula:
230 = l · 12 1/2
Now we convert the 12 1/2 to an improper fraction so it is easier to solve.
Here's how you convert a mixed number to an improper fraction:
12 · 2 = 24
24 + 1 = 25
and put 25 over the original denominator
= 25/2
Now you can add that to the equation...
l · 25/2 = 230 (I put 230 on the right side because that is how I am used to solving equations, but you can leave it on the right side as well. It is up to you)
To get rid of fractions, multiply by the reciprocal (Basically you flip the fraction so that the numerator becomes the denominator and the denominator becomes the numerator) on both sides
25/2 · 2/25 cancels itself out
and
230/1 · 2/25...
230 · 2 = 460
1 · 25 = 25
So you would get 460/25
Thus, we end up with:
l = 460/25
Divide 460 by 25 and you get 18.4...
Technically 18.4 is the answer but in decimal form.
If you want it in fraction form, just take 0.4 and put it over 10 because 0.4 is in the tenths place. 4/10 simplifies down to 2/5...
Therefore, the answer is 18 2/5 feet.

Answer:

Step-by-step explanation:
The time it takes for an object dropped from a height to reach the ground is given by the function time (in seconds) =(1/4)√h where h is the initial height in feet. If an object dropped from a building takes 4 seconds to reach the ground what is height of the object was dropped from, to the nearest foot?
Answer:
256 ft
Step-by-step explanation:
Assuming f(t)=(1/4)√h, we can solve for h by setting 4=(1/4)√h.
4=(1/4)√h
16=√h
h= 16^2 =256 ft
Step-by-step explanation:
h = (4 ÷ ¼)²
h = (4 × 4)²
h = 16² = 256ft
Using Substitution solve: y=x+5
4x+y=20
Answer:
3
Step-by-step explanation:
So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3
