Aris and Josiah are reading a 50-page book for their ELA class. Aris wants to know what page Josiah is reading. Josiah gives her two hints: 1. The product of the two page numbers he can see is 930. 2. The page he is reading is an odd-numbered page. What page is Josiah reading?

Answers

The two pages the boys are reading are pages 31, and 30. I'm not sure which is which. (would depend on who is reading the odd number page).

Josiah is reading page 31. The page he is reading is an odd-numbered page is 31 by factorizing number.

Step 1: Determine the factors of 930.

The factors of 930 are 1, 2, 3, 5, 6, 10, 15, 31, 62, 93, 155, 186, 310, 465, and 930.

Step 2: Identify the factors that correspond to odd-numbered pages in the book.

Since Josiah is reading an odd-numbered page,  eliminate the even factors.

This leaves  with the odd factors:

1, 3, 5, 15, 31, 93, 155, and 465.

Step 3: Determine which odd factor corresponds to a page number within the range of the book.

Since the book has 50 pages,  eliminate the odd factors greater than 50. This leaves us with the odd factors: 1, 3, 5, 15, and 31.

Step 4: Identify the odd factor that, when multiplied by its complement, equals 930, that is:

31 × 30 = 930,

so Josiah is reading page 31.

Therefore, Josiah is reading page 31 of the book.

Julia drove a car 10 miles in 30 minutes. Jasmine drove a motorcycle 3 miles in 12 minutes. who drove faster? show work!

Answers

Julia = 10 miles in 30 minutes

Jasmine = 3 miles in 12 minutes

Julia= 10/30 *2 = 20/60. Julia drove 20 mph

Jasmine= 3/12*5= 15/60. Jasmine drove 15mph

Julia drive faster.

Julia is driving at 20miles/hour while jasmine drives at 15miles/hour.
I got these values by relating 10miles in 30 minutes to miles/hr so i multiplied by 2 since there are 2 half hours in a mile. And 12 mins is 1/5 of an hour so i multiplied 3miles/12 mins by 5 to get miles an hour. So julia was driving faster

Step-by-step explanation:

So we know that the radius of the corner shelf is 10.5 inches. So first you write down the formula for finding the area of a circle. The formula for finding the area of a circle is:

A= pi x r squared

A= 3.14 x 10.5 squared

A= 3.14 x 110.25

The correct option B: (-9/4 × 3/2)×(6/3 × 5/7) = -9/7×(3/2×6/3)×5/7 is the associative property of multiplication.

What is defined as the associative property of multiplication?"Associate" means to join or connect with something. The associative property of multiplication states that when multiplying three numbers, the end result will always be the same regardless of how the numbers are grouped.The associative property of multiplication refers to the fact that the order in which three numbers are multiplied has no effect on the result.Because multiplication is built on addition, the associative property is only after addition and multiplication. Subtraction and division are not subject to the law of associativity.

The formula for associative property of multiplication is-

a×(b×c) = (a×b)×c

For four digits;

(a×b)×(c×d) = a×(b×c)×d

Thus, from the given option the condition for associative law is only satisfied in option B.

(-9/4 × 3/2)×(6/3 × 5/7) = -9/7×(3/2×6/3)×5/7

Thus, the correct option for the associative property of multiplication s chosen.

How to calculate the value?

From the information, it was stated that doctors recommend us to eat between 3 to 8 percent of our bodyweight each day and that one day someone eats 7.2 pounds.

It should be noted that based on the information given, the highest percentage which is 8% will be used for the calculation.

Therefore, the biggest weight the person can be will be:

8% of x <= 7.2

0.08x <= 7.2

x <= 7.2/0.08

x <= 90 pounds

Therefore, the biggest weight the person can be based on the recommendation by the doctor is 90 pounds.

Solve the following radical equations.
2√x =√(x+1)

Answers

The solution for the radical equation 2√x =√(x+1) is x=1/3

The phrase "algebraic expression" refers to any arrangement of terms that have undergone operations like addition, subtraction, multiplication, division, etc. (or variable expression).. Let's use the equation 5x + 7 as an example. Thus, 5x + 7 is an illustration of an algebraic expression.

Eliminate the radical on the both sides by squaring on both sides-

Both sides must be raised to the second power

(2√x)²=(√x+1)²

After squaring we get 4x=x+1

Solving the equation-

We get rearranged equation as 4x=x+1

3x=1    x=1/3

Check if the  solution is correct by putting it in original equation-putting x=1/3 in the equation 2√x =√(x+1)

2×√1/3=√1/3+1

4/3=4/3

Therefore, the solution for the radical equation 2√x =√(x+1) is x=1/3.

what is the probability that at least one of the top three cards in a well shuffled deck of cards is a jack, queen, or king?

Answers

The probability that at least one of the top three cards is a jack, queen, or king is 0.289%.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

A deck has a total of 52 cards.

A deck of cards has four jacks.

A deck of cards has four queens.

A deck of cards has four kings.

The total number of jacks, queens, and kings is 4 + 4 + 4 = 12.

Then the probability that at least one of the top three cards is a jack, queen, or king will be:

P = ( 12 / 52 ) × ( 8 / 51 ) × ( 4 / 50 )

P = ( 6 / 26 ) × ( 8 / 51 ) × ( 2 / 25)

P = 96 / 33150

              [tex]A = P(1 + {r}/{n})^{tn}[/tex]        (1)

    where , A  = future amount or the final amount

                  P = principal amount to be invested

Write each equation in logarithmic form.
8=(1/2)⁻³

Answers

The logarithmic form of 8 = (1/2)⁻³ is given by log₍₁/₂₎(8) = -3.

The logarithm is exponentiation's opposite function in mathematics. This means that the logarithm of a fixed number, base b, represents the exponent to which that fixed number must be raised in order to create a particular number x.. The logarithm counts the number of times the same factor appears during repeated multiplication in the simplest scenario.

The given exponential form of the equation is 8 = (1/2)⁻³

To transform this exponential form into logarithmic form, we are requested.

Consider the given exponential form: 8 = (1/2)⁻³

Taking logarithm on both sides with the base as (1/2), we get,⇒ log₍₁/₂₎(8) = log₍₁/₂₎(1/2)⁻³

Now using the logarithmic rule logₐ(aⁿ) = n × logₐ(a) in the RHS of the above equation, we get

⇒ log₍₁/₂₎(8) = (-3) × log₍₁/₂₎(1/2)

⇒ log₍₁/₂₎(8) = (-3) × 1                  

(Since logₐ(a) = 1, for a &gt; 0)

⇒ log₍₁/₂₎(8) = -3

Therefore, the logarithmic form of 8 = (1/2)⁻³ is given by log₍₁/₂₎(8) = -3.

Question 10
When choosing a loan, which of the following scenarios is best?

1Points
A
lower APR, shorter loan, and extra principal payments

B
lower APR, longer loan, and extra interest payments

C
higher APR, shorter loan, and make interest payments

Answers

When choosing a loan, the best scenario is lower APR, shorter loan, and extra principal payments.

How to illustrate the information?

A loan is a type of debt that a person or other entity incurs. The lender advances the borrower a certain amount of money, typically on behalf of a business, financial institution, or government. The borrower accepts a specific set of terms in return, which may include any financial costs, interest, a repayment schedule, and other requirements.

APR represents the total yearly cost of a loan to the borrower, including all fees. The APR is stated as a percentage, just like an interest rate. It does, however, contain other costs or fees such as mortgage insurance, the majority of closing costs, discount points, and loan origination fees, unlike an interest rate. It should be noted that the APR simply means the annual percentage rate which is the interest that's generated on the amount borrowed.

Therefore, it should be noted that when choosing a loan, the best scenario is a lower APR, shorter loan, and extra principal payments

This is important in order to reduce the value that the person will pay and make it easier to return the loan.

A line that includes the points (h,3) and (9, –3) has a slope of –1. What is the value of h?

Answers

The value of h is 3

How to find a point in a coordinates using the slope?

The line that includes the point (h, 3) and (9, -3) has a slope of -1.

Using the slope intercept equation,

y = mx + b

where

m = slopeb = y-intercept

Therefore,

y = mx + b

y = -x + b

using (9, - 3)

-3 = - 9 + b

b = -3 + 9

b = 6

Therefore, the equation is as follows:

y = -x + 6

using (h, 3)

y = -(h) + 6

3 = -h + 6

-h = 3 - 6

-h = -3

h = 3

Therefore, the value of h is 3.
