Answer:
Smallest number = 172
Step-by-step explanation:
Two consecutive even integers have a sum of 346.
Let x be the smallest number.
We have other number = x + 2
We also have
x + x + 2 = 346
2x + 2 = 346
2 x = 344
x = 172
Smallest number = 172, Other number = 172 + 2 = 174
Smallest number = 172

find the apporximate side length of a square game board with an area of 151 in2
To find the approximate side length of a square game board with an area of 151 in², take the square root of 151.
Explanation:To find the approximate side length of a square game board with an area of 151 in2, we can use the formula for the area of a square, which is length x width. Since all sides of a square are equal, we can represent the side length as 's'. So, s x s = 151. To find the side length, we can take the square root of 151, which is approximately 12.29 inches. Therefore, the approximate side length of the square game board is 12.29 inches.
Write the decimal number in standard form
Six and five hundred and sixteen ten-thousandths
The decimal number 'six and five hundred and sixteen ten-thousandths' in standard form is 6.0516, which combines the whole number six with the fractional part written as a decimal. Scientific notation is not necessary here since the number is already reasonably simple.
Explanation:To express the number six and five hundred and sixteen ten-thousandths in standard form, you start by identifying the whole number and the fractional part. The whole number is six, which is straightforward. The fractional part is five hundred and sixteen ten-thousandths, which refers to 516 over 10000. In decimal form, this is written as 0.0516. Combining the whole number with the fractional part gives us the decimal 6.0516. This is the number in standard notation.
Scientific notation simplifies the expression of very large or very small numbers. For example, a large number like 306,000,000 can be written as 3.06 × 108, and a small number like 0.000028 can be expressed as 2.8 × 10-5. However, the number 6.0516 is already concise enough that converting it to scientific notation isn't necessary.

it takes trevon ten hours to clean an attic. cody can clean the same attoc in seven hours.find how long it would take them if they worked together.
If Trevon takes 10 hours to clean the attic and Cody takes 7 hours to clean the same attic, it would take them approximately 4.11 hours to clean the attic if they worked together.
Explanation:If Trevon takes 10 hours to clean the attic and Cody takes 7 hours to clean the same attic, we can find the rates at which they clean per hour. Trevon cleans at a rate of 1/10 of the attic per hour, and Cody cleans at a rate of 1/7 of the attic per hour. To find out how long it would take them if they worked together, we add their rates: 1/10 + 1/7 = 17/70. This means that together, they can clean 17/70 of the attic per hour.
To find out how long it would take for them to clean the whole attic, we divide 1 (representing the full attic) by their combined rate: 1 / (17/70) = 70/17 = 4.11 hours (rounded to the nearest hundredth).

The weight of a sack of potatoes was more than 11 pounds. Shana wants to write an inequality for the weight of the sack of potatoes. What constant should she use in the inequality?
Answer: The constant that Shana should use in the inequality is 11.
Step-by-step explanation: Given that the weight of a sack of potatoes was more than 11 pounds and she wants to write an inequality for the weight of the sack of potatoes.
We are to find the constant that she should use in the inequality.
Let x pounds represents the weight of the sack of potatoes.
Then, according to the given information, the inequality can be written as
[tex]x>11.[/tex]
Thus, the required constant that Shana should use in the inequality is 11.
Nina has 5 bills and 10 bills in her wallet. She has a. total of 7 bills with a value of $55. How many of each type of Bill does she have?
Answer:
4 tens3 fivesStep-by-step explanation:
If all were $5 bills, the total would be $35. It is $20 more than that. Each time a $5 bill is replaced by a $10 bill, the total goes up $5. Since the total is $20 higher, there must be $20/$5 = 4 such replacements.
There are 4 $10 bills and 3 $5 bills.

how to find the density of a unknown liquid, the volume is 12.0mL and the mass is 6g.
To calculate the density of an unknown liquid given its mass of 6g and volume of 12.0mL, divide the mass by the volume, resulting in a density of 0.5 g/mL.
Explanation:To find the density of an unknown liquid with a volume of 12.0mL and a mass of 6g, you need to use the formula for density which is density = mass/volume. Given the mass is 6g and the volume is 12.0mL, you substitute these values into the formula to calculate the density.
Therefore, the calculation would be: density = 6g / 12.0mL = 0.5 g/mL.
This states that the density of the unknown liquid is 0.5 g/mL, which means for every milliliter of this liquid, it weighs 0.5 grams. Understanding the density of a substance can be crucial in identifying it since density is a characteristic property.
mr. lee had a bag of red beans and a bag of black beans. 20% of the total number of beans were black, and there were 180 ounces more red beans than black beans. he transferred some red beans to the bag containing black beans, so that, the bag now contained 30% of the total number of beans. How many ounces of beans were there in the bag of mixed beans
Final answer:
After finding the total weight of beans based on the given percentages and difference in weight between red and black beans, we determine that there are 90 ounces of beans in the mixed bag.
Explanation:
The question asks us to find out how many ounces of beans are now in the bag of mixed beans, given certain percentages before and after mixing. We know that initially, 20% of the total beans are black, and the rest are red. After Mr. Lee transferred some red beans to the bag containing black beans, the bag contained 30% of the total number of beans.
To solve this, let's denote the total number of beans by T, the number of black beans by B, and the number of red beans by R. According to the information provided:
20% of T is black beans: B = 0.20TThere are R = B + 180 oz of red beans.After transferring, the mixed bag contains 30% of T.First, we use the initial conditions to write an equation for the total number of beans T. Since R is 180 ounces more than B:
T = B + R
T = B + (B + 180)
T = 2B + 180
Given that B is 20% of T, we can also write this as:
T = 2(0.20T) + 180
T = 0.40T + 180
We can now solve for T:
T - 0.40T = 180
0.60T = 180
T = 180 / 0.60
T = 300 ounces
Since we know that the mixed bag contains 30% of the total, we calculate 30% of 300 ounces:
30% of T = 0.30 x 300
30% of T = 90 ounces
Therefore, after transferring, there are 90 ounces of beans in the mixed bag.

90% of students at a university use a backpack, while the rest do not. Of all the students, 50% carry their laptops with them and 5% carry neither a backpack nor laptop. What percentage of students carry their laptops and use a backpack?
The percentage of students who carry their laptops and use a backpack is 45%.
Explanation:To find the percentage of students who carry their laptops and use a backpack, we need to subtract the percentage of students who carry neither a backpack nor laptop from the percentage of students who carry their laptops.
Given that 5% carry neither a backpack nor laptop, we can subtract this from the 50% who carry their laptops to find that 45% of students carry their laptops and use a backpack.

how would you simplify -2+3i/-3-2i (im doing conjugates in math right now)
To simplify -2+3i/-3-2i, multiply both the numerator and denominator by the conjugate of the denominator (-3+2i).
Explanation:To simplify -2+3i/-3-2i, we can multiply both the numerator and denominator by the conjugate of the denominator, which is -3+2i. This will help us eliminate the imaginary terms in the denominator.
Multiplying the numerator and denominator, we get:
(-2+3i)(-3+2i) / (-3-2i)(-3+2i)
Expanding and simplifying:
(6i+4i^2-9+6i) / (9+4)
Combining like terms:
(-9+12i+4i^2) / 13
Since i^2 is equal to -1, the expression becomes:
(-9+12i-4) / 13
Combining like terms:
(-13+12i) / 13
Therefore, the simplified form of -2+3i/-3-2i is (-13+12i) / 13.
