How many plastic cubes can fit into the box?
Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box = [tex]2\frac{1}{2}=\frac{5}{2}[/tex] ft
Height of the box = 2 ft
Volume of the box = length × width × height
[tex]$=4\times\frac{5}{2} \times2[/tex]
= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube = [tex]\frac{1}{2}[/tex] ft
Volume of the cube = length × length × length
[tex]$=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2}[/tex]
[tex]$=\frac{1}{8} \ \text{ft}^3[/tex]
Volume of the cube = 0.125 ft³
[tex]$\text{Number of plastic cubes}=\frac{\text{Volume of box}}{\text{Volume of cube}}[/tex]
[tex]$=\frac{20}{0.125}[/tex]
= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.

Find the volume of the cone
Enter and exact answer in terms of pi or use 3.14 for pi and round your answer to the nearest hundredth
Answer:
Find 6.75% of 260
Step-by-step explanation:
Hi
To find the volume of a cone, you use the formula 1/3πr²h, substituting in the radius for r and the height for h. For an example cone with a radius of 4 and a height of 9, the volume would be 48π or approximately 150.72 after rounding to the nearest hundredth.
Explanation:The student is asked to find the volume of a cone. The formula to find the volume of a cone is 1/3πr²h, where r is the radius of the base of the cone and h is the height of the cone.
If the student is given the radius and the height, they would just need to substitute the values into the formula. For example, if the radius of the cone is 4 and the height is 9, the volume would be 1/3 * π * (4)² * 9 = 48π. If the student prefers a decimal approximation, they can substitute pi with 3.14 to get 150.72, rounded to the nearest hundredth.

What is the center of a circle whose equation is x2 + y2 – 12x - 2y + 12 = 0?
(-12, -2)
O (-6, -1)
(6, 1)
O (12, 2)
Solution:
Given equation of circle is:
[tex]x^{2} +y^{2} -12x-2y+12=0[/tex]
Move the constant to other side
[tex]x^{2} +y^{2} -12x-2y = -12[/tex]
Group the equation
[tex](x^{2} -12x)+(y^{2}-2y)=-12[/tex]
Add 36 and 1 from both sides
[tex](x^{2} -12x +36)+(y^{2}-2y + 1)=-12 + 36 + 1\\\\(x^{2} -12x + 36)+(y^{2}-2y + 1)= 25[/tex]
Which is simplified as:
[tex](x - 6)^2 + (y-1)^2 = 25[/tex] --------- eqn 1
The equation of circle is given as:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Where, r is radius and (h, k) is center
Compare eqn 1 with above general equation
(h, k) = (6, 1)
Thus the center of a circle is (6, 1)
Answer:
the center the circle is (6,1)

The points (5, 3), (3, -4), (10, 3), and (8, -4) are the vertices of a polygon. What type of polygon is formed by these points?
Answer:
Parallelogram
Explanation:
Since there are four points, this is a quadrilateral.
There is a slope during the points. Therefore it could not be a rectangle nor square. The sides are still parallel though.
The length is not equal too, so it could not be a rhombus.
If you plot these points to the graph and connect them, it would form a parallelogram.
Answer:
a parallelogram
Step-by-step explanation:
When the points are connected to form a convex polygon, that polygon is a parallelogram.

what do you add to 2 1/8 to make 4
Final answer:
To make a total of 4 starting with 2 1/8, you need to add 1 7/8, which is the difference between 4 written as a fraction (32/8) and 2 1/8 (17/8).
Explanation:
To find what you need to add to 2 1/8 to make 4, you follow these steps:
First, you need to write the number 4 as a fraction with the same denominator as 2 1/8. Since 1/8 is the fractional part of 2 1/8, you can write 4 as 32/8 (because 4 × 8 = 32).
Next, you subtract the fraction 2 1/8 from 32/8. The whole number 2 is the same as 16/8 (because 2 × 8 = 16). So 2 1/8 is the same as 17/8 (because 16 + 1 = 17).
Now, subtract 17/8 from 32/8 to get the difference. 32/8 - 17/8 = 15/8.
The fraction 15/8 can also be written as 1 7/8 (because 15 ÷ 8 = 1 with a remainder of 7).
Therefore, you need to add 1 7/8 to 2 1/8 to make 4.
In the figure below, PDW and WTC are right triangles. The measure of WPD is 30°, the measure of WC is 6 units, the measure of WT is 3 units, and the measure of WD is 12 units. Determine the measure of PD .
Answer:
PD = 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the tangent ratio in right Δ PDW and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex], then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{WD}{PD}[/tex] = [tex]\frac{12}{PD}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
PD = 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using similarity it can be solved as:
[tex] In\:\triangle PDW\: \& \: \triangle CTW\\\\
\angle PDW \cong \angle CTW.... (each\:90 °) \\\\
\angle PWD \cong \angle CWT... (Vertical\:\angle s) \\\\
\therefore \triangle PDW\: \sim\: \triangle CTW\\
(by \:AA\: criterion \: of\: similarity) \\\\
\therefore \frac{PW}{CW} =\frac{WD}{WT}.. (csst) \\\\
\therefore \frac{PW}{6} =\frac{12}{3}\\\\
\therefore \frac{PW}{6} =4\\\\
\therefore PW=4\times 6\\\\
\huge \red {\boxed {\therefore PW=24}} \\\\
In\:\triangle PDW\:, \angle PWD = 60°\\\\

2x + 5
rewrite each expression as the product of a constant and a sum of terms
Answer:
= 2(x+[tex]\frac{5}{2}[/tex] )
Step-by-step explanation:
2x + 5
= 2(x+[tex]\frac{5}{2}[/tex] )
When:
2 is the constant
(x+[tex]\frac{5}{2}[/tex] ) is a sum of terms
Hope it will find you well.
The expression 2x + 5 can be written as the product of 1 and the sum 2x + 5. Therefore, it's 1(2x + 5).
Step 1:
Factor out the greatest common factor.
In the expression 2x + 5, there is no common factor other than 1 since both terms do not share any common factors.
Step 2:
Rewrite as the product of a constant and a sum of terms.
We rewrite 2x + 5 as the product of 1 and the sum of 2x and 5: [tex]\(1 \times (2x + 5)\).[/tex]
Step 3:
Perform the multiplication.
Multiplying 1 by the sum (2x + 5) gives us [tex]\(1 \times (2x + 5) = 2x + 5\)[/tex].
Step 4:
Interpret the result.
The expression [tex]\(2x + 5\)[/tex] represents the original expression 2x + 5 as the product of the constant 1 and the sum of terms 2x and 5. This expression is now in the form requested.
How did the graph of f(x) = x^2 and g(x) = 3/4 x^2 relate?
g(x) = [tex]\frac{3}{4} f(x)[/tex] or g(x) is 3/4 times of f(x) , F(x) and g(x) have common solution or intersecting point in the graph parabola at x=0 i.e. in origin and x = [tex]\frac {4}{3}[/tex].
Step-by-step explanation:
We have a function f(x) = [tex]x^{2}[/tex] and another function , g(x) = [tex]\frac{3}{4} x^{2}[/tex]. In the graph of y = [tex]x^{2}[/tex] , the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point.
Graphing y = (x - h)2 + k , where h = 0 & k = 0
Function g(x) can be formed with compression in function f(x) by a factor of 3/4 , i.e. g(x) = [tex]\frac{3}{4} f(x)[/tex] or g(x) is 3/4 times of f(x).Domain and range of f(x) and g(x) are same ! Although structure of both functions is same the only difference is g(x) is compressed vertically by a factor 3/4. Both are graph of a parabola with vertex at (0,0). Also, F(x) and g(x) have common solution or intersecting point at x=0 i.e. in origin.

Find the 97th term of the arithmetic sequence
25
,
29
,
33
,
.
.
.
25,29,33,...
Step-by-step explanation:
The given sequence is 25, 29, 33, ....
The sequence represents arithmetic progression
In an AP, the first term is a1 = 25
The difference between two terms, d = 29 - 25 = 4
To find the 97th term,
By formula, [tex]a_{n} = a_{1} + (n - 1) d[/tex]
Substituting the values in the above equation, we get
[tex]a_{97} = 25 + (97 - 1) 4[/tex]
= 25 + (96 * 4)
= 25 + 384
= 409
The 97 th term in the given sequence is 409.
The 97th term of the arithmetic sequence 25,29,33,... can be calculated using the formula: a+(n-1)*d. In this case, the 97th term equals 409.
Explanation:The subject of your question is arithmetic sequences. In an arithmetic sequence, every term is a certain amount greater than the previous term. This difference is known as the common difference. In your question, the sequence is 25, 29, 33, ..., indicating the common difference is 29-25, which equals 4.
To calculate the 97th term of an arithmetic sequence, we can use the formula: a + (n-1) * d where 'a' is the first term, 'n' is the term you're looking for, and 'd' is the common difference.
So, for your question, we input the necessary values and calculate: 25 + (97-1)*4 = 25 + 96*4 = 25 + 384 = 409.
Therefore, the 97th term of the arithmetic sequence you provided is 409.
