which object has a weight of approximately 1 ounce?​

Answer:

3

Step-by-step explanation:

5 times a number would be 5x, then increase that by 4 is 5x+4.  The problem then says 5x + 4 ≥ 19.  If we solve for x then we get x ≥ 3 so x has to be greater than or equal to 3, so the smallest number it could be is 3.  You can even try any number smaller than 3 and see it doesn't work.  even something like 2.9

Answer:

x ≥ 3  

Step-by-step explanation:

Let the number = x

5 × the number = 5x

Increased by 4 means 5x +4

   Is at least 19 means ≥ 19

5x + 4 ≥ 19

5x       ≥ 15      Subtracted 4 from each side

 x       ≥    3      Divided each side by 5

The smallest possible number that satisfies the conditions is x = 3.

Answer:

[tex]\large\boxed{(x-5)^2+(y-3)^2=5^2\to(x-5)^2+(y-3)^2=25}[/tex]

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the end points of a diameter (8, 6) and (2, 0). The midpoint of a diameter is a center of a circle. Half of a length of diameter is a length of a radius.

The formula of a midpoint of a segment:

[tex]\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)[/tex]

Substitute:

[tex]x=\dfrac{8+2}{2}=\dfrac{10}{2}=5\\\\y=\dfrac{6+0}{2}=\dfrac{6}{2}=3[/tex]

The center of a circle is (5, 3).

The formula of a length of a segment:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute:

[tex]d=\sqrt{(2-8)^2+(0-6)^2}=\sqrt{(-8)^2-(-6)^2}=\sqrt{64+36}=\sqrt{100}=10[/tex]

The length of a diameter is 10 units. The length of a radius r = 10 : 2 = 5 units.

Finally we have the equation of a circle:

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

9282 divided by 433 with a remainder is equal to 21.

Given data:

To divide 9282 divided by 433, we can use variables to represent the numbers and perform the division algebraically.

Let's denote 9282 as a dividend (D) and 433as divisor (d).

D = 9282

d = 433

We need to find the quotient (Q) when D is divided by d.

Q = D / d

Substituting the given values:

Q = 9282 / 433

To simplify the division, we can multiply both the numerator and denominator by a suitable power of 10 to eliminate the decimal point. In this case, multiplying by 10 will suffice:

Q = (9282 * 10) / (433* 10)

Q = 9282 / 433

Now, we can perform the division:

Q = 9282 / 17

So, Q = 21

The quotient is the final answer, and the remainder is 0. Therefore, 9282 divided by 433 with a remainder is equal to 21.

Answer:

x = - 5, x = 4

Step-by-step explanation:

To find the zeros set f(x) = 0, that is

(x + 5)(2x - 8) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4

Answer:

X = -5 or x = 4

Step-by-step explanation:

F(x)=(x+5) (2x-8)

When f(x) = 0

0 =(x+5) (2x-8)

Thus;

x+5 =0 or  2x-8 = 0

Therefore; x= -5 or x = 4

The answer is 9.6 km/hour.

Answer:

statistical question

Step-by-step explanation:

A distribution is the arrangement of data values. The center for data refers to the central tendency measures such as mean, median, and mode. Variability describes the spread of values, often measured by standard deviation.

A distribution is how data values are arranged. The part of the data set where the middle values are concentrated is called the center for data. A survey anticipates that there will be different answers when gathering info. Variability is a measure that describes the spread of values in a data set.

To find the center of a data set, we can calculate measures of central tendency, which include the mean, median, and mode. The mean, or average, is the total of all data values divided by the number of values. The median is the value at the midpoint of the data set when ordered from smallest to largest, effectively splitting the data into two equal parts. The mode is the most frequently occurring value in the data set. If your data set has outliers, the median is often the best measure of the center, as it is less affected by extreme values.

When we refer to variability in a data set, we are often talking about the standard deviation, which tells us how spread out the data values are around the mean. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation suggests the values are spread out over a wider range.

Answer:

The correct answer is B) p(x) = -14x - 15

Step-by-step explanation:

To find this, start by writing the function as indicated.

p(x) = r(x) - c(x)

Now input the functions into the appropriate spots.

p(x) = -10x - (4x + 15)

p(x) = -10x - 4x - 15

p(x) = -14x - 15

Answer:

[tex]P(x) =14x-15[/tex]

Step-by-step explanation:

The revenue from selling x necklaces [tex]r(x)= -10x[/tex]

The cost of buying x necklaces is [tex]c(x)= 4x+15[/tex]

The profit from selling x necklaces is [tex]P(x) = r(x)- c(x)[/tex]

Replace r(x) and c(x)

[tex]P(x) =-10x-(4x+15)[/tex]

[tex]P(x) =-10x-4x-15[/tex]

[tex]P(x) =14x-15[/tex]

Step-by-step explanation:

If we know two sides of a triangle a and b, the third side, c, can be no bigger than the the other two sides added together, and no smaller than the other two sides subtracted

a-b < c < a+b

We know the two sides are 7 and 5

7-5 < c < 7+5

2 < c < 12

Answer:

TT→T

Step-by-step explanation:

If p is false, then ~p is true.

If q is false, then ~q is true.

Now note that

In your case, both~p and ~q are true, then ~p→~q is true too (or TT→T)

The truth value of the conditional statement ∼p → ∼q is true when both p and q are false, as the conditional is false only when the antecedent is true and the consequent is false.

The question is asking us to evaluate the truth value of the conditional statement ∼p → ∼q when both p and q are false. According to the rules of propositional logic, the implication (→) is false only when the antecedent is true and the consequent is false. Here, since p and q are both false, the antecedent (∼p) is true and the consequent (∼q) is also true. Therefore, the conditional statement is true. This reflects the concept that a conditional statement is always true if either the antecedent is false or the consequent is true, hence in our case the truth value of ∼p → ∼q is true.

Answer:

50 units

Step-by-step explanation:

Think of it as taking steps.  Each unit is a step.  It will take you 50 steps to get from -50 to 0, so the distance is 50

Mathematically, end point minus starting point

0 - (-50) =

0+50 = 50

Hey there!

I want you to think of radicals as like terms. In order to be able to combine like terms, you need the same base and exponent.

For example,

3x^2-y^2 <== same exponent but not same variable

3x^2-x^2 <=== could be combined because exponent (^2) and variable (x) are the same

So, for this question, you're looking for a radical that has 5 under the radical sign and 3 above the radical sign.

"B" is the right answer, because is  ∛ and in the radical it has a √5.

I hope this helps!

Answer:

6

Step-by-step explanation:

The correct notation is: Summation from n = 1 to infinity of the expression:

[tex]4(\frac{1}{3} )^{n-1}[/tex]

If we expand this notation, we will find that the given summation represent the terms of a G.P and we have to find the sum of infinite terms of a G.P. By placing n=1,2,3,4,... we can find the first few terms as shown below:

[tex]4(\frac{1}{3} )^{1-1}=4\\\\ 4(\frac{1}{3} )^{2-1}=4(\frac{1}{3} ) \\\\ 4(\frac{1}{3} )^{3-1} =4(\frac{1}{3} )^{2}[/tex]

Its obvious from the above result, that the given summation represent a G.P with first term equal to 4 and common ratio of 1/3. The formula of infinite G.P is:

[tex]S=\frac{a_{1} }{1-r}[/tex]

Using the value of a1 = 4 and r = 1/3 we can calculate the given summation

[tex]S=\frac{4}{1-\frac{1}{3} }=6[/tex]

Therefore, the given summation is equal to 6.

Answer:

[tex]\frac{8}{25}[/tex]  square miles

Step-by-step explanation:

The relationship between the side length (let it be s) of a square and its diagonal (let it be d) is given by:

[tex]s=\frac{d}{\sqrt{2} }[/tex]

Since d is given as 4/5, we solve for s:

[tex]s=\frac{d}{\sqrt{2} }\\s=\frac{\frac{4}{5}}{\sqrt{2} }\\s=\frac{4}{5\sqrt{2} }[/tex]

NOW, area of square is s^2 where s is the side length.

Area = [tex]s^2=(\frac{4}{5\sqrt{2} })^2=\frac{16}{50}=\frac{8}{25}[/tex]

The area of the park is:[tex]\[\boxed{\frac{8}{25} \text{ square miles}}\][/tex]

To find the area of the square park given the length of the diagonal, we need to use the relationship between the side length of a square and its diagonal.

[tex]\[d = s\sqrt{2}\][/tex]

Given that the diagonal [tex]\( d \) is \(\frac{4}{5}\)[/tex] miles, we can set up the equation:

[tex]\[s\sqrt{2} = \frac{4}{5}\][/tex]

[tex]\[s = \frac{\frac{4}{5}}{\sqrt{2}} = \frac{4}{5\sqrt{2}}\][/tex]

Rationalize the denominator by multiplying the numerator and the denominator by [tex]\(\sqrt{2}\):[/tex]

[tex]\[s = \frac{4\sqrt{2}}{5 \cdot 2} = \frac{4\sqrt{2}}{10} = \frac{2\sqrt{2}}{5}\][/tex]

[tex]\[A = \left( \frac{2\sqrt{2}}{5} \right)^2\]\[A = \frac{(2\sqrt{2})^2}{5^2} = \frac{4 \cdot 2}{25} = \frac{8}{25}\][/tex]

Therefore, the area of the park is:

[tex]\[\boxed{\frac{8}{25} \text{ square miles}}\][/tex]

Answer:  x - 2

Step-by-step explanation:

HCF is more commonly referred to as GCF (greatest common factor)

Factor each expression to see which factor(s) they have in common.

[tex]x^4 - 8x\implies x(x^3-8)\\= x\boxed{(x-2)}(x^2+4x+4)\\\\\\3x^2-8x+4\implies 3x^2-6x-2x+4\implies3x(x-2)-2(x-2)\\=(3x-2)\boxed{(x-2)}\\\\\\2x^2-5x+2\implies 2x^2-4x-x+2\implies 2x(x-2)-1(x-2)\\=(2x-1)\boxed{(x-2)}[/tex]

The only factor that all three expressions have in common is: x - 2

Final answer:

To round 0.660 to the nearest tenth, we find that 0.660 rounded to the nearest tenth is 0.7.

Explanation:

To round 0.660 to the nearest tenth, we need to look at the digit in the hundredth place, which is 6. Since 6 is greater than or equal to 5, we round up. The digit in the tenth place becomes 7, and all digits after the tenths place are dropped. Therefore, 0.660 rounded to the nearest tenth is 0.7.
