Answer:

Option B. 1,200.

Step-by-step explanation:

Regina is in charge of purchasing notepads to  give away at an upcoming trade show.

she knows that 65 boxes of notepads will contain a total of 1,625 pads.

We calculate this by unitary method. first we calculate the amount of pads in one box.

∵  65 boxes contains = 1,625 pads

∴  in one box = 1,625 ÷ 65 = 25 pads

She purchases 48 boxes, so she will receive = 25 × 48 = 1,200 pads

She would receive 1200 pads if she purchases 48 boxes.

Step-by-step explanation:

Given

2x - [tex]\frac{3}{x}[/tex] = 1

Multiply through by x

2x² - 3 = x ( subtract x from both sides )

2x² - x - 3 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

The factors are + 2 and - 3

product = 2 × - 3 = - 6 and sum = 2 - 3 = - 1

Use these factors to split the x- term

2x² + 2x - 3x - 3 = 0 ( factor the first/second and third/fourth terms )

2x(x + 1) - 3(x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(2x - 3) = 0

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

165\15= number of tubs

The blue dot on the number line has a value of 6.

To determine the value of the blue dot on the number line, we need to understand the spacing between consecutive dots. Given that the fifth dot is marked as 2 and the seventh dot is marked 10, we can calculate the spacing between each consecutive dot.

The spacing between each pair of dots is given by:

[tex]\[ \text{Spacing} = \frac{\text{Value of Seventh Dot} - \text{Value of Fifth Dot}}{\text{Number of Dots between}} \][/tex]

Substitute the given values:

[tex]\[ \text{Spacing} = \frac{10 - 2}{7 - 5} = \frac{8}{2} = 4 \][/tex]

Now, calculate the value of the blue dot:

[tex]\[ \text{Value of Blue Dot} = \text{Value of Fifth Dot} + (\text{Spacing} \times \text{Number of Dots to the Blue Dot}) \][/tex]

[tex]\[ \text{Value of Blue Dot} = 2 + (4 \times 1) = 6 \][/tex]

Therefore, the blue dot on the number line has a value of 6.

Answer:

3.24

Step-by-step explanation:

You would use the two fonts given to find the scale factor.

So the scale factor would be 10.4976/5.832 = 1.8

So if the scale factor is 1.8 we can use that to find the font size just before that. To do this you would divide the font size by the scale factor.

So

5.832/1.8 = 3.24

The font size just before 5832 is 3.24.

Associativity property of Addition 

Step-by-step explanation:

The associate property defines that grouping of more than two numbers and performing the basic arithmetic operations of addition and multiplication does not affect the final result. Note that grouping means placing the parenthesis.

The property used in this equation is the associative property of addition.

Associative property states that changing the order in which addends are grouped has no effect on the sum.

(a + b) + c = a + (b + c)

The equation given in the question is:

3 + [7 + (–4)] = [3 + 7] + (– 4)

The associative property states that (a + b) + c = a + (b + c)

Both equations are matching.

Hence, the equation given in the question clearly follows the associative law of addition.

Step-by-step explanation:

If J is Joan's current age and E is Ellen's current age, then:

J = E + 5

(J - 3) + (E - 3) = 17

Solve the first equation for E:

E = J - 5

Substitute into the second:

(J - 3) + (J - 5 - 3) = 17

Answer: May 1st

Step-by-step explanation:

They have pay initially the down payment of 5% and the first month's installment.

You should start on May 1, because if you want to get it for her for Christmas.

Option D is correct.

The monthly payment is the amount paid per month to pay off the loan in the time period of the loan.

Down payment is the initial deposit made by the buyer to the seller when purchasing an expensive item, such as residential property or a car.

According to the question

Bryson and his cousins plan to all chip in to get their grandmother a $250 Christmas present.

They make a down payment of 5% and pay $30 a month after that.

If the payments are due at the beginning of each month, then they have to pay the first month's installment with their down payment.

That means they have pay initially the down payment of 5% and the first month's installment.

Total price = $250

Down payment = $250 x 5% = $12.5

Remaining amount = 250 - 12.5 = 237.5

= [tex]\frac{237.5}{30} =7.91[/tex] ≈ 8 months

You should start on May 1, because if you want to get it for her for Christmas.

May to December is 8 months.

Answer:

about 54% of the people surveyed were females

Step-by-step explanation:

to calculate the % of females out of everyone, you need to add everyone up, and then add up only the females.

119+150+447+735+1174+103+171+512+710+756=4877

4877 is the Total number of people surveyed

119+150+447+735+1174=2625

2625 is the total number of females surveyed

so

to convert 2625/4877 to a %, first turn it into a decimal

2625/4877=0.538

now multiply 0.538 by 100

0.538*100=53.8%

so about 54% of the people surveyed were females

D) about 54% of the people were women

Step-by-step explanation:

The vertex form of a quadratic function is

[tex]y=a(x-h)^2+k[/tex]                 .... (1)

Where, (h,k) is vertex and x=h is the axis of symmetry.

The given function is

[tex]f(x)=-2(x+3)^2-5[/tex]           .... (2)

From (1) and (2), we get

[tex]a=-2,h=-3,k=-5[/tex]

The axis of symmetry is

[tex]x=h[/tex]

Substitute h=-3 in the above equation.

Hope my answer has helped you!

Solving exponential equations involves understanding exponential notation, the concept of logarithms, the rules of division in exponentials, and the relationship between the exponent and the decimal shifts.

To solve exponential equations, understanding exponential notation is crucial. This notation is used to express very large and very small numbers as a product of two numbers. The first number of the product referred to as the digit term, is usually not less than 1 and not equal to or greater than 10. The second component of the product considered the exponential term, is written as 10 with an exponent. Definitely, knowing about the squaring of exponentials is helpful, where you square the digit term in the typical way and multiply the exponent of the exponential term by 2.

What also comes in handy in this process is the concept of logarithms. For instance, the logarithm of a product of two numbers is the sum of the logarithms of the two numbers. To put it in a mathematical expression, log xy = log x + log y.

Moreover, when dealing with division in exponential equations, you typically divide the numbers out front and subtract the exponents. For example, if you have 10⁶ divided by 10³, you will get 10^(6-3) = 10³.

Lastly, the power or exponent of 10 is equal to the number of places the decimal is shifted. For example, 1,230,000,000 can be written as 1.23 × 10⁹, and 0.00000000036 can be written as 3.6 × 10⁻¹⁰.
