The larger number is 33 and the smaller number is 17.
Let the larger number be x
Then, the smaller number will be x-16
According to the question,
Larger number + smaller number = 50
So,
x+(x-16) = 50
2x = 50+16
2x = 66
x = 66÷2
x = 33
Hence,
Larger number = x = 33
Smaller number = x-16 = 33-16 = 17

Jane, Alan, and Ravi sent a total of 146 text messages over their cell phones during weekend, Ravi sent 8 fewer messages than Jane. Alan sent 4 times as many messages as Ravi. So as per question data,
Jane sent= 31 messages
Ravi sent= x-8= 31-8 = 23 messages
Alan sent= 4(x-8) = 92 messages
What operations are used here?The best way to solve an expression is from left to right if all the operations are the same (for instance, only addition, only subtraction, only multiplication, or only division). However, we must adhere to the order of operations for expressions including several operations.
The rule that dictates how to solve an expression involving numerous operations is known as the order of operations.
PEMDAS can help you remember that sequence. In PEMDAS, each letter denotes a mathematical operation.
Let, Jane sent x number of messages
Then, Ravi sent x-8 number of messages
and, Alan sent 4(x-8) number of messages
Total number of messages by them = 146
now,
x+(x-8)+4(x-8)=146
6x-40=146

Two similar boxes A and B are given with box B created by dividing box A's dimensions by 2.
Recall that the scale factor, k is the ratio of lengths of two corresponding sides of similar figures.
Since the dimensions of A were divided by 2 to form B, it follows that the scale factor of box A to box B is:
[tex]k=\frac{2}{1}[/tex]Also, recall the Similar Solids Theorem
It follows that the ratio of the volumes of the given solids is:
[tex]\frac{\text{Volume of A}}{\text{Volume of B }}=k^3=(\frac{2}{1})^3=\frac{2^3}{1^3}=\frac{8}{1}[/tex]Let the volume of box A be V₁ and let the volume of box B be V₂, it, therefore, implies that:
[tex]\frac{V_1}{V_2}=\frac{8}{1}[/tex]Substitute the value for the volume of box A into the equation, V₁=64:
[tex]\begin{gathered} \frac{64}{V_2}=\frac{8}{1} \\ Cross-Multiply_{} \\ \Rightarrow8V_2=64 \\ Divide\text{ both sides by 8:} \\ \Rightarrow\frac{8V_2}{8}=\frac{64}{8}\Rightarrow V_2=8\text{ cubic meters} \end{gathered}[/tex]Hence, the volume of box B is 8 m³.

Use the definition of a derivative to determine whether f(x) = 8x^2 is differentiable at x=0
The definition is option B No, it is not differentiable at x = 0.
Given,
The function, f(x) = 8x²
We have to find that the function is differentiable at x = 0.
So, lets check:
f(x) = 8x²
x = 0
f'(0) = [tex]\lim_{h\to \ 0}[/tex] [tex]\frac{f(0+h)-f(0)}{h}[/tex]
f(0 + h) = 8(0 + h)² = 8 (0 + 0 + h²) = 8h²
f(0) = 8 × 0² = 0
f(0 + h) - f(0) = 8h² - 0 = 8h²
f'(0) = [tex]\lim_{h \to \ 0}[/tex] 8h²/h = 8h = 8 × 0 = 0

the numbers between 1 to 2022 are written on a piece of paper.Caitlin circles the even numbers with red circles and nicole circles the multiples of 5 with yellow circles.How many numbers are circled with only one color?
The number of numbers circled with only one color found using arithmetic progression formula are 809 numbers
What is an arithmetic progression?An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms in the sequence is constant
The given parameters are;
The set of the numbers written on the paper = Numbers from 1 to 2022
Numbers circled with red circles by Caitlin = All even numbers between 1 and 2022
Numbers Nicole circles using yellow = Numbers that are multiples of 5
Required; The number of numbers that are circled with one colour only
Solution; The even numbers are numbers that are a multiple of 2
The number of even numbers between 1 and 2022 are found using arithmetic progression formula as follows;
[tex] a_{n} = a_{1} + (n - 1)\cdot d[/tex]
Where;
[tex]a_{1}[/tex] = The first term = 2 (First even number)
d = The common difference = 2
n = The number of terms
Given that 2022 is an even number, we have;
[tex] a_{n} = 2022 = 2 + (n - 1)\cdot 2[/tex]
Which gives;
[tex] \displaystyle {n = \frac{(2022 - 2)}{2} + 1 = 1011} [/tex]
We note that 10 is the lowest common multiple of 2 and 5, which gives;
Multiples of 10 have two colors, therefore, the numbers that have only one color is given by the difference between the number of even numbers and the number of multiples of 10 as follows;
The number of multiples of 10 are;
[tex] \displaystyle {n = \frac{(2020 - 10)}{10} + 1 = 202} [/tex]

One triangle is the scaled factor of the other
So, the triangles are similar shapes
As a general rule, the following are the properties of a scaled copy of another figure

We need to distribute 7/8 of a gallon into cups of 1/16 of a gallon. It means that to know the number of cups, we need to divide 7/8 into 1/16.
So, let's remember how to make a division between two fractions:
[tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot d}{b\cdot c}[/tex]Then, the division of 7/8 into 1/16 is equal to:

By median , test scores of 40 students are listed below. So five number summary is 25, 58,72,81,98
What are median in math?
The middle number is obtained by sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers). Example: Because the number 4 is in the middle when the numbers are ordered (1, 4, 7), it is the median of 4, 1, and 7.First we need to sort the data from Smallest to largest data value which is allready sorted
n = 40
Five number summary can be calculated as
Minimum = 25
Q1 can be calculated as
Lower Half of 40 values is 20, so median of 20 values will give us 25th percentile so Median = (20+1)/2 = 10.5th here 10th value is 57 and 11th value is 59 so Q1 = (57+59)/2 = 58
Median = (n+1)/2 = (40+1)/2 = 20.5th value and 20th and 21st value is 72 so median = (72+72)/2 = 72
Upper 20 values after median will provide us Q3 or 75th percentile which can be calculated as 20+(20+1)/2 = 30.5th value so 30th value is 81 and 31st value is also 81. So Q3 = (81+81)/2 = 81
Max = 98
So five number summary is 25, 58,72,81,98
And correct boxplot for this data is A. Boxplot A is correct which shows correct five number summary.

Use the long division method to find the result when 8x^3-18x^2+24x+3 is divided by 4x-1. If there is a remainder, express the result in the form q(x)+r(x)/b(x).
Answer:
2x^2 -4x +5 +8/(4x -1)
Step-by-step explanation:
You want to divide 8x^3-18x^2+24x+3 by 4x-1 using polynomial long division.
Polynomial long divisionPolynomial long division is similar to numerical long division, except that the quotient term is always the ratio of the leading dividend term to the leading divisor term.
As with numerical long division, the dividend at each step is reduced by the product of the quotient term and the divisor.
When the dividend is of lower degree than the divisor, the division is finished. That dividend is the remainder.
The attachment shows the division in detail. Your result is ...
q(x) +r(x)/b(x) = (2x^2-4x+5) +(8)/(4x-1)
What is the value of x in the equation x^2 + 2 = 0
Answer:
[tex]{ \tt{ {x}^{2} + 2 = 0 }} \\ \\ { \tt{ {x}^{2} = - 2 }} \\ \\ { \tt{x = \sqrt{ - 2} }}[/tex]

The estimate where the number of books is enough is 254,000
What is the estimation of a number?The estimation of numbers is the approximation of the said number.
This means that the estimation of a number is close to the said number, but it has a slight different value
How to estimate the number of books?The number of books is given as
Number of books = 253,625
From the question, we understand that:
You want to make sure that the number of books is enough
This means that we estimate the number of books to a number greater than 253,625
A good way to do this is to approximate to the nearest thousand
When the number is approximated to the nearest thousand, we have
Estimate = 254,000

To find the x-intercept, simply but y=0 in the equation given and solve for x
That is;
3x - 4y = 12
3x - 4(0) = 12
3x = 12
Divide both-side of the equation by 3
x= 4
The x-intercept is;
(4, 0)
To find the y-intercept, simply put y=0 in the equation given and then solve for y
That is;
3x - 4y = 12
3(0) - 4y = 12
-4y = 12
Divide both-side of the equation by -4
y = -3
The y-intercept is (0, -3)
Hence, the correct option is B.

[tex]a=180-78\Rightarrow a=102[/tex]angle a has a measurement of 102°.
*We will have by alternate exterior angles that c has a measurement of 58°.
*By supplementary angles, we will have that the measurement of angle d equals:
[tex]d=180-58\Rightarrow d=122[/tex]angle d has a measurement of 122°.
