What is 549,423 rounded to the nearest thousand
Rounding 549,423 to the nearest thousand involves looking at the hundreds of places. Since it's lower than 5, the thousand's place remains the same, rendering 549,000 as the rounded number.
Explanation:Rounding 549,423 to the nearest thousand involves examining the hundreds place, which contains a 4. In rounding, if this number is less than 5, you leave the thousands place as it is and change everything to its right to zeros. If it's 5 or more, you increase the thousands place by one and change everything to its right to zeros.
Therefore, because the number in the hundreds place in 549,423 is 4 - which is less than 5 - we don't round up. We leave the thousands place '549' as is and change the hundreds, tens, and ones place to zeros. Hence, 549,423 rounded to the nearest thousand is 549,000.

A spherical model of planet Earth has a radius of 3 ft.
What is the approximate volume of the model of planet earth?
Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.
Enter your answer in the box.
Answer:
The approximate volume of the model of planet earth is [tex]113.04\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the sphere is equal to
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
we have
[tex]r=3\ ft[/tex]
substitute
[tex]V=\frac{4}{3}(3.14)(3^{3})=113.04\ ft^{3}[/tex]
The approximate volume of a spherical model of Earth with a radius of 3 ft is calculated using the formula V = (4/3)πr³, which results in a volume of 113.04 cubic feet when rounded to the nearest hundredth.
Explanation:To calculate the approximate volume of a spherical model of planet Earth with a radius of 3 ft, we use the formula for the volume of a sphere, which is V = (4/3)πr³. Plugging in the values, we get V = (4/3) × 3.14 × (3 ft)³. Performing the calculation, we first cube the radius (3 ft × 3 ft × 3 ft = 27 ft³), then multiply by π (approximately 3.14), and finally multiply by 4/3. So, V = (4/3) × 3.14 × 27 ft³ = 113.04 ft³.
When we round to the nearest hundredth, the approximate volume of the model is 113.04 cubic feet.
A piece of popcorn, on average, has a volume of 1.125 inches cubed. How many pieces of popcorn will fit in a bag that has a dimension of 5 inches by 3 inches by 7 inches?
To find out how many pieces of popcorn will fit in a bag with dimensions of 5 inches by 3 inches by 7 inches, divide the bag's volume by the average volume of a popcorn piece.
To calculate the volume of popcorn that fits in the bag:
Calculate the volume of the bag: 5 in x 3 in x 7 in = 105 in³.
Divide the bag's volume by the average volume of a piece of popcorn (105 in³ ÷ 1.125 in³ = 93.33 popcorn pieces).

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1.5 m. What is the surface area of the outside of one of the bins? Drag and drop the correct answer into the box. 3.375 91 1.25 13.5
m??
Answer: [tex]13.5\text{ m}^2[/tex]
Step-by-step explanation:
Given: Cubic bins with closed tops are used to transport melons to the farmers market.
The edge length of each bin = 1.5 m
We know that the surface area of cube is given by :-
[tex]\text{S.A.}=6(\text{edge})^2\\\\\Rightarrow\text{S.A. of cubic bin}=6(1.5)^2\\\\\Rightarrow\text{S.A. of a cubic bin}=13.5\text{ m}^2[/tex]
Hence, the surface area of a cubic bin=[tex]13.5\text{ m}^2[/tex]

A 14-ounce box of cereal sells for $2.10. what is the unit rate.
Final answer:
To find the unit rate for a 14-ounce box of cereal selling for $2.10, divide the price by the number of ounces to get $0.15 per ounce.
Explanation:
The unit rate for a 14-ounce box of cereal selling for $2.10 can be calculated by dividing the price of the box by the number of ounces it contains. To find the unit rate, you would perform the following calculation:
Unit rate = Price per box ÷ ounces per box
Unit rate = $2.10 ÷ 14 ounces
Unit rate = $0.15 per ounce
Therefore, the unit rate or cost per ounce for the cereal is $0.15.

A 1 1/2-pound piece of turkey costs $7.98. A 6-ounce package of the same sliced turkey costs $2.49. What is the difference in price per 3-ounce serving?
The difference in price per 3-ounce serving package is $0.2475.
Price Per Serving CalculationFirst, we need to determine the cost per 3-ounce serving for each type of turkey packaging. Since there are 16 ounces in 1 pound, a 1 1/2-pound piece of turkey is equivalent to 24 ounces.
Cost per ounce for the 1 1/2-pound turkey: $7.98 \/ 24 ounces = $0.3325 per ounce.
Cost per 3-ounce serving for the 1 1/2-pound turkey: $0.3325 x 3 = $0.9975.
The 6-ounce package costs $2.49, so:
Cost per ounce for the 6-ounce package: $2.49 \/ 6 ounces = $0.415 per ounce.
Cost per 3-ounce serving for the 6-ounce package: $0.415 x 3 = $1.245.
The difference in price per 3-ounce serving between the two types of turkey is: $1.245 - $0.9975 = $0.2475.
If the sum of the positive integer a and 5 is less than 12, what is the sum of all possible values of a?
To find the sum of all possible values of a, we subtract 5 from both sides of the inequality a + 5 < 12 and find the maximum value of a. The sum of all possible values of a is 21.
Explanation:To find the sum of all possible values of a, we need to determine the range of possible values for a. We are given that the sum of a and 5 is less than 12. This can be expressed as a + 5 < 12. To find the maximum value of a, we subtract 5 from both sides of the inequality: a < 12 - 5 = 7. Therefore, the possible values of a are all the positive integers less than 7. To find the sum of all these values, we can use the formula for the sum of consecutive positive integers: S = (n/2)(n+1), where n is the largest integer. In this case, n = 6, so the sum of all possible values of a is (6/2)(6+1) = 21.
The sum of all possible values of a is 21.
Explanation:The question states that the sum of the positive integer a and 5 is less than 12. To find the sum of all possible values of a, we need to determine the range of values that satisfy this inequality. Let's set up the inequality:
a + 5 < 12
Subtract 5 from both sides:
a < 7
So, the possible values of a are all positive integers less than 7. To find the sum of all these values, we can use the formula for the sum of an arithmetic series:
Sum = (n/2)(first term + last term)
Here, the first term is 1 and the last term is 6 (since we want integers less than 7). The number of terms, n, is 6, since there are 6 possible values of a. Plugging in these values:
Sum = (6/2)(1 + 6) = 3 * 7 = 21
So, the sum of all possible values of a is 21.

Write in slope-intercept form an equation of the line that passes through the given points. (−9, 5), (−3, 3)
The slope intercept format is y = -1 / 3x + 2
The slope intercept formula is represented as follows
y = mx + bwhere
m = slope
b = y-intercept
Therefore, let's find m using the coordinates (-9, 5)(-3, 3)
m = 3 - 5 / -3 - (- 9) = -2 / 6 = - 1 / 3
let's find b using the coordinate(-3, 3)
3 = -1 / 3 (-3) + b
3 = 1 + b
b = 2
