Milton got a paperweight like the one shown below. He needs to fill it with sand to give it weight.
If a = 2 inches, what is the volume of the paperweight?
A.24 in3
B.56 in3
C.16 in3
D.32 in3
Solution:
Given that, Milton got a paperweight like the one shown in the figure.
The Paper Weight is in the shape of a cuboid and a cube.
Length and breadth of cuboid is a and height of the cuboid is 2a, whereas side of cube is a.
The volume of sand required to fill in the Paper Weight , is equal to the volume of the Paper weight,
Volume of Paper Weight = Volume of cube + Volume of cuboid
We know that, Volume of cube =[tex] (side)^{3} [/tex]
and , Volume of Cuboid = [tex] length \times breadth \times height [/tex]
Volume of Paper Weight = [tex] a^{3}+ (a\times a \times2a)= a^{3} +2a^{3} = 3a^{3} [/tex]
Given that , a = 2 inches , then Volume of Paper Weight = [tex] 3 \times (2)^{3}= 3\times 8 = 24 [/tex]
[tex] 24 \: in^{3} [/tex] is the volume of the paperweight.
Option A is the correct solution.

Charlotte's annual salary is 29,354 dollars. She is hoping to win the World Lottery which has a grand prize of 6,156,782,221 dollars. Approximately how many times as large is the World Lottery's grand prize as Charlotte's annual salary?
The World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary when dividing the grand prize amount by her annual salary.
To determine approximately how many times larger the World Lottery's grand prize is compared to Charlotte's annual salary, we perform a division of the two amounts. Charlotte's annual salary is $29,354, and the World Lottery grand prize is $6,156,782,221.
To find out how many times larger the lottery prize is than Charlotte's salary, we use the following calculation:
Lottery Prize to Salary Ratio = World Lottery Grand Prize / Charlotte's Annual Salary
Lottery Prize to Salary Ratio = $6,156,782,221 / $29,354 ≈ 209,701
This means that the World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary.
Note: This is a simplified approximation and does not take into account any deductions or taxes that would be applied to either the grand prize or the salary.
Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5), C'(-2,-2) triangle are congruent when reflected over the x-axis.
Final answer:
The reflection rule over the x-axis is when a point (x, y) reflects to (x, -y). Applying this rule to triangle A(-1,7), B(6,5), C(-2,2) gives us the reflected points that match the coordinates of A'(-1,-7), B'(6,-5), C'(-2,-2), proving the triangles are congruent.
Explanation:
The student is querying about the reflection of a triangle over the x-axis on a coordinate plane, specifically within the domain of Mathematics. To demonstrate that triangles A(-1,7), B(6,5), C(-2,2) and their reflected counterparts A'(-1,-7), B'(6,-5), C'(-2,-2) are congruent, we will use the reflection rule associated with reflections over the x-axis.
The reflection rule states that when a point (x, y) is reflected over the x-axis, the resulting point will be (x, -y). Applying this rule:
For point A(-1, 7), the reflection over the x-axis would be A'(-1, -7).
For point B(6, 5), the reflection would be B'(6, -5).
For point C(-2, 2), the reflection would be C'(-2, -2).
The reflected points A', B', and C' match the coordinates given for the congruent triangle, thus confirming the triangles are congruent using the reflection rule over the x-axis.

A cell phone plan includes 450 anytime minutes for $35 per month, plus $18.85 for a cell phone and $25 for a one-time activation fee. let x represent the number of months of service. write an equation in the form y equals mx plus
b. find the ordered pair associated with the equation for xequals9. if you sign a 1-yr contract, how much will this cell phone package cost?
The cost of the cell phone plan over x months is represented by the equation y = 35x + 43.85. For 9 months, the total cost is $359.85, and for a 1-year contract, the total annual cost is $463.85.
The total monthly cost of the cell phone plan for x months of service can be represented by the linear equation y = 35x + 18.85 + 25. Here, y represents the total cost, x represents the number of months, 35 is the cost per month, 18.85 is the cost of the cell phone, and 25 is the one-time activation fee. The equation simplifies to y = 35x + 43.85, since the cost of the phone and the activation fee is a one-time charge, independent of the number of months.
For x = 9 months of service, the ordered pair is (9, y), where y = 35(9) + 43.85. Therefore, the ordered pair associated with x = 9 is (9, 359.85).
If you sign a 1-year contract, which is 12 months, you will pay y = 35(12) + 43.85, which results in a total cost of $463.85 for the year.

What is the value of a for the following circle in general form? x^2+y^2+ax+by+c=0
The 'a' in the equation refers to the coefficient influencing the horizontal shift of a circle's center. To find 'a', you often need specifics about the circle, such as its center or radius. When such information is provided, the quadratic formula can be used to solve it.
Explanation:The given equation x2+y2+ax+by+c=0 represents the general form of a circle equation. The value of 'a' is a coefficient that impacts the horizontal shift of the circle along the x-axis. Unfortunately, without specific values attached, it is impossible to directly calculate 'a'. Nevertheless, if the equation is compared to the completed square form of a circle equation, i.e., (x-h)2+(y-k)2=r2, you can ascertain that 'a' would be -2h, where h is the x-coordinate of the circle's center.
In specific examples, for instance, if a = 1, b = 0.0211, and c = -0.0211, we can solve for x using the quadratic formula -b ± √b² - 4ac divided by 2a yielding -0.0211 ± √(0.0211)2 − 4(1)(−0.0211)/2(1), where 'a', 'b', 'c' are the coefficients from the equation of a circle in its general form.

Jason is decorating his house and decides to paint one of the bedrooms blue. One tin of 500mL blue paint costs $11.50. To finish the whole bedroom, he needs 4L of blue paint. How much will it cost Jason to paint this bedroom?
Jason needs 4L of blue paint to paint a bedroom. At 500mL per tin costing $11.50 each, he will need 8 tins, totaling $92.00 for the paint.
The question asks to calculate the total cost of blue paint Jason needs to paint a bedroom. Jason requires 4L (4000mL) of paint and one 500mL tin costs $11.50. Since 4000mL is eight times 500mL, we will need eight tins of paint. To find the total cost, we multiply the cost of one tin by the number of tins needed:
Cost of one tin of paint = $11.50
Number of tins needed = Total volume required / Volume of one tin = 8
Total cost = Cost of one tin times Number of tins = $11.50 times 8 = $92.00.
Therefore, it will cost Jason $92.00 to buy the blue paint needed to paint the bedroom.
