Step-by-step explanation:

To measure length to the nearest fourth inch, use a ruler or measuring tape that shows inches and fractions of an inch. Align the beginning of the ruler or tape measure with one end of the object and identify the nearest one-fourth inch mark.

When measuring length to the nearest fourth inch, you can use a ruler or a measuring tape that shows inches and fractions of an inch. Start by aligning the beginning of the ruler or tape measure with one end of the object you want to measure. Then, identify the nearest one-fourth inch mark on the ruler or tape measure and record the measurement. For example, if the object aligns with the 3 1/4 inch mark, the length can be recorded as 3 1/4 inches.

Answer:

¹⁶⁹⁰/₃π cm³ ≈ 1769.76 cm³

Step-by-step explanation:

Equation of a volume of a cone: V = ¹/₃ * πr²h

1. Find r (radius): r = d/2 = 26/2 = 13 cm

2. Plug in everything into equation: V = ¹/₃ * π(13)² * 10

3. Square: V = ¹/₃ * π * 169 * 10

4. Multiply: V = ¹⁶⁹⁰/₃π cm³ ≈ 1769.76 cm³

if it has a diameter of 26 cm, then its radius is half that, or 13.

[tex]\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=13\\ h=10 \end{cases}\implies V=\cfrac{\pi (13)^2(10)}{3} \\\\\\ V=\cfrac{1690\pi }{3}\implies V\approx 1769.76[/tex]

length* width

12*10= 120

Volume /120

960/120=8

height is 8 inches

For this case we have that by definition, the formula of the midpoint is given by:

[tex]MP = (\frac {x_ {1} + x_ {2}} {2}, \frac {y_ {1} + y_ {2}} {2})[/tex]

We have the points are:

[tex](x_ {1}, y_ {1}) :( 9,8)\\(x_ {2}, y_ {2}): (- 1, -2)\\MP = (\frac {9 + (- 1)} {2}, \frac {8 + (- 2)} {2})\\MP = (\frac {9-1} {2}, \frac {8-2} {2})\\MP = (\frac {8} {2}, \frac {6} {2})\\MP = (4,3)[/tex]

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.

Answer:

500.874

Step-by-step explanation:

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

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.

Answer:

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.

x + 68 = 100 ( subtract 68 from both sides )

x = 32° → D

Answer:

8x + 12y < 240

Step-by-step explanation:

If x equals the number of small rugs and y equals the number of medium rugs dyed, we would need to multiply both variables by the number of hours taken to dye each sized rug. It takes 8 hours to dye a small rug (8x), and 12 hours to dye a medium rug (12y).

Then, to find the total number of hours they dye them in, add the terms together.

8x + 12y

The company must dye the rugs in less than 240 hours, so we will use a 'less than' (inequality) sign (it cannot be 240, or any more than 240).

8x + 12y < 240

Step-by-step explanation:

we know that

In a reflection across the y-axis the y-coordinate remains the same, but the x-coordinate is transformed into its opposite

we have

[tex]f(x)=2(0.4)^{x}[/tex]

The reflection of f(x) across the y-axis is equal to the function g(x)

[tex]g(x)=2(0.4)^{-x}[/tex]

A counterexample is a special type of example that is an exception to a general rule, law, proposition or statement. Hence if we prove that [tex]sin(45^{\circ})+cos(45^{\circ})\neq 1[/tex] then this is a counterexample for the expression [tex]sin(x)+cos(x)=1[/tex]. Thus:

[tex]sin(x)+cos(x)=1 \\ \\ Substituting \ x=45^{\circ} \ we \ have: \\ \\ sin(45^{\circ})+cos(45^{\circ})=1 \\ \\\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}=1 \\ \\ Rewriting:\\ \\2\frac{\sqrt{2}}{2}=1 \\ \\ \therefore \sqrt{2}=1 \ FALSE![/tex]

Answer:

A

Step-by-step explanation:

Given

x³ +x ² - 6x ( to find the zeros equate to zero ), that is

x³ + x² - 6x = 0 ← factor out x from each term

x(x² + x - 6) = 0

To factorise the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)

The factors are + 3 and - 2, since

3 × - 2 = - 6 and 3 - 2 = + 1, hence

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

Equate each factor to zero and solve for x

x = 0

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

The zeros are x = - 3, x = 0, x = 2 → A

Since this is a linear question in y=mx+b form, and where m is the slope of the line and b is the y-intercept....

The slope in this problem is 2/3

And y intercept is -1

So you would graph the point -1 on y axis then go up 2/3 since it’s positive( go up 2 over 3)

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

J - 3 + J - 8 = 17

2J - 11 = 17

2J = 28

J = 14

Joan is 14, so in 7 years, she will be 21.

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.
