The volume of the rectangular prism is 24 inches cube.
What is volume?Volume is the scalar quantity of any object that specified occupied space in 3D.
For example, the space in our room is referred to as volume.
Volume has units of cube example meter³,cm³, etc.
The volume of cuboid = length × height × width.
The volume of the cube = side³.
Given the rectangular prism with a bunch of small cubes whose volume is 1/4 inches³.
Number of small cubes = 8 × 4 × 3 = 96
The volume of the complete prism = Volume of 1 cube × the Number of small cubes.
The volume of the complete prism = 1/4 × 96
The volume of the complete prism = 26 inch³.
Hence "The volume of the rectangular prism is 24 inches cube".

SA =? - in2
Answer:
SA = 360π in²
Step-by-step explanation:
The slant height l is the hypotenuse of the right triangle inside the cone.
Using Pythagoras' identity to find l
l² = 24² + 10² = 576 + 100 = 676 ( take the square root of both sides )
l = [tex]\sqrt{676}[/tex] = 26
Then
SA = πrl + πr²
= (π × 10 × 26) + (π × 10²)
= 260π + 100π
= 360π in²

A. square root property
[tex]3x^2-192=0\\x^2-66=0\\x^2=66\\x= -\sqrt{66} or \sqrt{66}[/tex]
it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format
B. factorising
[tex]x^2-x-6=0\\x^2+2x-3x-6=0\\(x+2)(x-3)=0\\x+2=0 and x-3=0\\x= -2 \\x= 3[/tex]
i just felt like this was easier to factorise than the other 2 options left
C. Completing the square
[tex]x^2-6x-7=0\\(x-3)^2=0\\x= -1\\x= 7[/tex]
same reason personal preference
D- Quadratic
[tex]x^2-17x-7=0\\x=\frac{-(-17)+\sqrt{(-17)^2-4(1)(-7)} }{2(1)} \\x=\frac{-(-17)-\sqrt{(-17)^2-4(1)(-7)} }{2(1)}\\x=17.4\\x=-0.402[/tex]

Q1.) A carton contains 25 cards numbered 1 to 25. Alecia picks a card randomly. What is the probability that Alecia will pick an odd number?
Answer:
52%
Step-by-step explanation:
Since there are 25 numbers in 1-25, you need to divide 100/25 which is 4.
There are 13 odd numbers in 1-25 so you need to multiply 13x4.
13x4=52
There is a 52% chance she will pick an odd number.

What are the coordinates of the point obtained if the point A=(3,7) is rotated 180 degrees about the origin?
A. (-3,7)
B. (-3,-7)
C. (-7,-3)
D. (-7,3)
Answer:
B. (-3, -7)
Step-by-step explanation:
Anytime you rotate a number 180° about the origin, the numbers in the coordinates become their opposites.
-3 is the opposite of 3 and -7 is the opposite of 7.
Therefore, your new coordinates are (-3, -7)
(x,y) becomes (-x,-y)

Dr. Baker, a veterinarian, recorded the weight of each newborn kitten her office saw today.
Kittens' weights (g)
100
120
140
160
180
200
Answer:
30 grams is the answer
As per the given data, the interquartile range of the kittens' weights is 60 g.
What is interquartile range?The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles.
The IQR is the range between the first quartile (Q1) and the third quartile (Q3). It represents the range of the middle 50% of the data set.
To find the interquartile range (IQR) of the kittens' weights, we need to first find the median and the quartiles.
Find the median (Q2):
The median is the middle value when the data is arranged in order. In this case, we have an even number of data points, so we take the average of the two middle values:
100, 120, 140, 160, 180, 200
The middle values are 140 and 160, so the median is:
(Q2) = (140 + 160) / 2 = 150
Find the first quartile (Q1):
The first quartile is the middle value of the lower half of the data. To find Q1, we take the median of the lower half:
100, 120, 140
The median is 120, so Q1 is:
Q1 = 120
Find the third quartile (Q3):
The third quartile is the middle value of the upper half of the data. To find Q3, we take the median of the upper half:
160, 180, 200
The median is 180, so Q3 is:
Q3 = 180
Calculate the interquartile range:
The interquartile range is the difference between the third and first quartiles:
IQR = Q3 - Q1 = 180 - 120 = 60
Therefore, the interquartile range of the kittens' weights is 60 g.
