Which of the following is a measurement of the space between two objects? A. Area B. Pounds C. Circumference D. Miles
Final answer:
The space between two objects is measured as distance or length, with miles being the correct unit of measurement among the given options.
Explanation:
The measurement of the space between two objects is referred to as length or distance. If we look at the options provided: A. Area, B. Pounds, C. Circumference, D. Miles, it is clear that miles is a unit of measurement that describes distance. Area measures the size of a surface, pounds measure weight or mass, and circumference measures the distance around a circle. When considering distances, especially those that are long such as between two cities, miles is an appropriate unit to use. For example, the distance between your house and school would best be measured in kilometers or miles, rather than in smaller units like inches or centimeters, or in unrelated units like pounds or areas.
Answers matching "The combined average weight of an okapi and a llama is 450 kilograms. The average weight of 3 llamas is 190 kilograms more than the average weight of one okapi. On average, how much does an okapi weigh, and how much does a llama weigh?"
Let us say that:
x = weight of llamas
y = weight of okapi
From the problem, we can create the equations:
x + y = 450 --> 1
3 x = y + 190 --> 2
Rewriting equation 1:
x = 450 – y
From equation 2:
3 (450 – y) = y + 190
1350 – 3 y = y + 190
4 y = 1160
y = 290
From equation 1:
x = 450 – 290
x = 160
Therefore a llama weighs 160 kilograms while okapi weigh 290 kilograms on average.

Rajendra has 14 4/5 pounds of trail mix. He is putting them into bags that hold 1 1/2 pounds each. Does he have enough trail mix to completely fill 8 bags?
Answer: Yes , Rajendra has enough trail mix to completely fill 8 bags.
Step-by-step explanation:
Given : Total trail mix Rajendra has = [tex]14\dfrac{4}{5}[/tex] pounds
Convert [tex]14\dfrac{4}{5}[/tex] into improper fraction.
[tex]14\dfrac{4}{5}=\dfrac{(14)(5)+4}{5}=\dfrac{74}{5}[/tex]
Amount of mix in each bag = [tex]1\dfrac{1}{2}[/tex] pounds.
[tex]=\dfrac{1(2)+1}{2}=\dfrac{3}{2}[/tex] pounds
Then, the total number of bags can be filled by the trail mix Rajendra has
= Total trail mix ÷ Amount of mix in each bag
[tex]=\dfrac{74}{5}\div\dfrac{3}{2}[/tex]
[tex]=\dfrac{74}{5}\times\dfrac{2}{3}=\dfrac{148}{15}=9.86666666667\approx9[/tex]

I would like to create a rectangular orchid garden that abuts my house so that the house itself forms the northern boundary. The fencing for the southern boundary costs $30 per foot, and the fencing for the east and west sides costs $15 per foot. If I have a budget of $120 for the project, what are the dimensions of the garden with the largest area I can enclose?
The largest rectangular orchid garden that can be enclosed within a $120 budget, considering the given costs of fencing, has dimensions of 2 feet by 2 feet, resulting in an area of 4 square feet.
You wish to create a rectangular orchid garden with the house forming the northern boundary, and you're working with a budget of $120 for fencing. The cost per foot for the southern boundary is $30, and for the east and west sides, it's $15 each. We need to determine the dimensions that maximize the area.
Let's denote the width of the garden (east and west sides) as w feet, and the length (only the southern side, as the northern side is the house) as l feet. The total cost of fencing is therefore the sum of the costs for all three sides: Cost = $30l + 2($15w), which simplifies to Cost = $30l + $30w. Since your budget is $120, we can write the equation $30l + $30w = $120, which simplifies further to l + w = 4.
To find the dimensions that give you the largest area, we need to maximize the area A of the rectangle, which is A = l imes w. Substituting w with 4 - l (from our previous equation), we get A = l imes (4 - l). To find the maximum area, take the derivative of A with respect to l and set it to zero, solving for l. This gives us l = 2 feet. Substituting back, we find w = 2 feet as well.
The dimensions for the garden that will give you the largest enclosed area within a $120 budget are 2 feet in width by 2 feet in length, resulting in an area of 4 square feet.

Monique Fournier deposited $12,500 into a savings account paying 6.5% annual interest compounded monthly. What amount will she have in her account after 3 years? How much compound interest will she have earned?
Explaining the calculation of the amount in the account after 3 years and the compound interest earned.
Amount in the account after 3 years:
Calculate the monthly interest rate: 6.5% annual interest divided by 12 (months) = 0.0054167
Calculate the total amount using the compound interest formula: $12,500 * (1 + 0.0054167)^36 = $15,183.41
Compound interest earned:
Subtract the initial deposit from the total amount: $15,183.41 - $12,500 = $2,683.41

To evaluate a triple integral over a region of a sphere, we switch to spherical coordinates. We then express the integrand and the limits of the variables in terms of these new coordinates. Don't forget the Jacobian when changing variables.
Explanation:The subject is a mathematical problem that requires evaluating a triple integral over a specific part of a ball in three-dimensional space. The function to integrate is f(x,y,z)=z*(x2+y2+z2)-3/2 and the region of integration is defined as the part of the sphere with radius 7 (x2+y2+z2<=49) in which z >= 3.5. Unfortunately, the solution to such a problem requires advanced mathematical skills and knowledge, such as spherical coordinates and integration techniques, which cannot be elaborated within the word limit here.
However, to solve such problems, you typically switch to spherical coordinates, where x=r*cos(theta)*sin(phi), y=r*sin(theta)*sin(phi), z=r*cos(phi). Then, you express your function and the limits of your variables r, theta, and phi in terms of these new coordinates. You need to consider the Jacobian determinant when changing variables. Eventually, you integrate over the specified region. The solution needs careful elaboration of every step due to the complexity of the integral.

Adam is constructing an equilateral triangle. He has already constructed the line segment and arcs shown.
What should Adam do for his next step?
A. Place the point of the compass on point X and draw an arc, using a width for the opening of the compass that is greater than 12XR.
B. Place the point of the compass on point X and draw an arc, using XR as the width for the opening of the compass.
C. Use the straightedge to draw XR←→ and XS←→.
D. Use the straightedge to extend RS¯¯¯¯¯ in both directions.
Answer:
C. Use the straightedge to draw XR←→ and XS←→.
Step-by-step explanation:
Adam has drawn the arcs by using RS distance as the radius of the circle and mid points as R and S.
So the point X is the same distance from R and S.
So now Adam has to use the straightedge to draw XR←→ and XS←→.
Then, XR = XS = RS
So it is an equilateral triangle.
Therefore, the correct answer is C.
Adam should do for his next step to use the straightedge to draw [tex]\( XR \)[/tex] and [tex]\( XS \).[/tex] The option (C) is correct.
The construction process for the equilateral triangle:
To construct an equilateral triangle using a straightedge and compass:
Construct [tex]\( XR \)[/tex]: Adam has already constructed segment [tex]\( XR \).[/tex]
Draw [tex]\( XS \)[/tex]: Using the straightedge, Adam should draw a line segment [tex]\( XS \)[/tex] from point [tex]\( X \)[/tex] to another point [tex]\( S \)[/tex] such that [tex]\( XS = XR \)[/tex]. This ensures that two sides of the equilateral triangle are equal in length.
Draw [tex]\( RS \)[/tex]: After drawing [tex]\( XS \)[/tex], Adam should use the straightedge to draw segment [tex]\( RS \)[/tex], completing the equilateral triangle [tex]\( \triangle XRS \).[/tex]
This method aligns with the steps typically used in geometric constructions to form an equilateral triangle: ensuring that all three sides are equal in length by first establishing two sides of equal length and then completing the triangle.
Therefore, upon reconsideration, option (C) is indeed the correct next step for Adam to construct his equilateral triangle.
