Write the ratio 4/12 as a decimal.
The ratio 4/12 converts to a decimal by dividing 4 by 12, resulting in 0.333 when rounded to the nearest thousandth.
To write the ratio 4/12 as a decimal, you simply divide the numerator (4) by the denominator (12). Let's do this step-by-step:
Divide 4 by 12, which equals 0.3333...
Since the division results in a repeating decimal, round it to the nearest thousandth for simplicity, which gives us 0.333.
The ratio 4/12 as a decimal is 0.333.
The top number (numerator) is what you're dividing, and the bottom number (denominator) is what you're dividing by.
In our case, 4 divided by 12.

2. The line segment graphed on the coordinate plane represents a roof with several triangular supports. Each support is triangular, with a horizontal board that starts on the edge of the roof and connects with a vertical board that ends on the edge of the roof as shown.
(a) Does each support have the same starting coordinates? Explain.
(b) Does each support have the same ending coordinates? Explain.
(c) Does each support have the same change in x-values? Explain.
(d) Does each support have the same change in y-values? Explain.
(e) Does each support have the same ratio of change in y-values over change in x-values? Explain.
Answer:
a) No, the first support starts at (0,0) and the 2nd one starts at (2,1)
b) No, first one ends at (2,1) 2nd one ends at (6,3)
c) No, 2 ( 0 to 2) does not equal 4 ( 2 to 6)
d) No, 1 ( 0 to 1) does not equal 2 (1 to 3)
e) Yes, this is the slope of the diagonal line: 1/2
Answer:
(a) No
(b) No
(c) No
(d) No
(e) Yes
Step-by-step explanation:
(a) No, they don’t. The starting position for the small triangle is (0,0). The starting position for the large triangle is (2,1).
(b) No, they don’t. The ending position for the small triangle is (2,1). The ending position for the large triangle is (6,3).
(c) No, they don't. 2 - 0 doesn't equal 6 - 2.
(d) No, they don't. 1 - 0 does not equal 3 - 1
(e) Yes, they do. 3-1/6-2 = 2/4 = 1/2
If 5/8 of the people in water aerobics class are over age 65 and 1/4 of the people in the class are under age 40,what fraction of the people in the class are either over 65 or under 40?
To find the fraction of people in the class who are either over 65 or under 40, we add the fractions of people in each age group. The maximum fraction is 1.
Explanation:To find the fraction of people in the class who are either over 65 or under 40, we need to add the fractions of people in each age group. First, we find the fraction of people over 65 by multiplying the total fraction by the fraction of people over 65: 5/8 * 1 = 5/8. Next, we find the fraction of people under 40 by multiplying the total fraction by the fraction of people under 40: 1/4 * 1 = 1/4. Finally, we add the two fractions together to find the total fraction of people who are either over 65 or under 40: 5/8 + 1/4 = 9/8. However, fractions cannot be greater than 1, so the maximum fraction is 1. Therefore, the fraction of people in the class who are either over 65 or under 40 is 1.

which number , when rounded to the nearest hundredth, is equal to 2.39?
Which number is a solution of the inequality 7x-5>-2? ( by the way that sign is supposed to be a less than or equal to)
A.-3
B.-1
C.0
D.1
Final answer:
The correct answer to the inequality 7x - 5 ≥ -2 is D. 1, since 1 is greater than 3/7 and thus satisfies the inequality.
Explanation:
To solve the inequality 7x - 5 ≥ -2, we need to isolate x. Follow these steps:
Add 5 to both sides of the inequality to cancel out the -5 on the left: 7x ≥ 3.
Divide both sides by 7 to solve for x: x ≥ 3/7.
Now we need to determine which of the provided options is a solution to the inequality. We have:
A. -3 (which is less than 3/7)
B. -1 (which is also less than 3/7)
C. 0 (which is again, less than 3/7)
D. 1 (which is greater than 3/7, making it a solution to the inequality)
The correct answer is D. 1 because it satisfies the given inequality.
Deshawn fuels 2 yachts and 6 barges. Each boat gets 126 gallons of fuel. To find how much fuel he needs for all the boats, deshawn first findsthe number of boats, then he uses an algorithm to multiply. Which are the three partial products deshawn could add to find the final product?
Deshawn, who fuels 2 yachts and 6 barges each with 126 gallons of fuel, can find the total fuel needed by calculating and summing three partial products; 800, 160 and 48, derived from breaking down the multiplication of 8 (total boats) and 126 (gallons per boat). The combined total is 1008 gallons.
Explanation:Deshawn needs to fuel 2 yachts and 6 barges, making a total of 8 boats. Each boat requires 126 gallons of fuel. Deshawn's algorithm for determining the total fuel required involves finding three partial products to multiply.
If we break down the multiplication of 8 (total boats) and 126 (gallons per boat), into three parts we get:
Multiplying 8 by 100 to get 800. Multiplying 8 by 20 (part of the 26 in 126) to get 160. Finally, multiplying 8 by 6 (the units digit in 126) to get 48.
These are the three partial products that Deshawn could add together (800 + 160 +48) to find the total fuel needed which is 1008 gallons.

W = 3x + 7y solve for y
Answer:
The value of the equation [tex]y=\frac{W-3x}{7}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]W = 3x + 7y[/tex]
We need to solve the provided equation for y.
Subtract 3x from both side.
[tex]W-3x= 3x-3x+ 7y[/tex]
[tex]W-3x=7y[/tex]
Divide both sides by 7.
[tex]\frac{7y}{7}=\frac{W-3x}{7}[/tex]
[tex]y=\frac{W-3x}{7}[/tex]
Hence, the value of the equation is [tex]y=\frac{W-3x}{7}[/tex].
To solve the equation W = 3x + 7y for y, subtract 3x from both sides and then divide by 7 to isolate y, resulting in the solution y = (W - 3x) / 7.
To solve for y in the equation W = 3x + 7y, we need to isolate y. First, we subtract 3x from both sides of the equation so that the terms with y are on one side:
W - 3x = 3x + 7y - 3x
This simplifies to:
W - 3x = 7y
Next, we divide both sides of the equation by 7 to solve for y:
(W - 3x) / 7 = y
Therefore, the solution for y in terms of W and x is y = (W - 3x) / 7.
Find the side length of a square with the given area. 121in(2 Exponent)
A.) 11 Inches.
B.) 60.5 Inches.
C.) 1,331 Inches.
D.) 14,641 Inches.
Answer:
A.) 11 inches
Step-by-step explanation:
There's a couple of ways to do this. If you know how to take a square root, use this way: [tex]\sqrt{121}[/tex] is equal to [tex]\sqrt{11*11}[/tex]. So that would mean that [tex]\sqrt{121} = \sqrt{11^{2} }[/tex]. Canceling it out (the square root of a square equals the original base), it equals 11. So the side length would be 11 inches.
Remember, we know the AREA and need to find the side length, so this is why we don't square 121 to get 14,641. 121 is the area and not the side length.
Hope this helps.
