___ power of 10 gives the answer 1,000,000,000? * 10 9 11 6
Answer:
9
Step-by-step explanation:
We see that we have 9 zeros.
We use the base 10 system to help us solve.
When we multiply anything by 10, we simply move the decimal place to the right.
Since we have 9 zeros, we move the decimal place 9 places to the right. Therefore, to get 1,000,000,000, we multiply 1 by 10⁹
Zero pairs are two numbers that _____ to get zero. 1. add 2. subtract 3. divide 4. multiply

x2 – 25 = - 4x – 4
Solve the quadratic by factoring
Answer:
x = -7, +3
Step-by-step explanation:
x² - 25 = -4x - 4
Put it all on one side
x² - 25 + 4x + 4 = 0
Put like terms together
x² + 4x - 21 = 0
Factor
(x + 7)(x - 3) = 0
x + 7 = 0 ⇒ x = -7
x - 3 = 0 ⇒ x = +3
x = -7, +3

Which is the definition of a ray?
a part of a line that has one endpoint and extends indefinitely in one direction
the set of all points in a plane that are a given distance away from a given point
lines that lie in the same plane and do not intersect
a part of a line that has two endpoints
The definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction
A ray is part of a line that has one endpoint and extends indefinitely in one direction and has the folowing properties.
It has one starting point called its endpoint. It does not have height or width but has length. But, its length is not measurable since it extends forever.So, the definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction.

A quantity P obeys the exponential growth law P(t)=e5t (t in years).
At what time t0 is P=15? Use yr for years. t0=?
At what time t1 is P=20? Use yr for years. t1= ?
What is the doubling time for P? Use yr for years. The doubling time is ?
Answer:
the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
the doubling time [tex]{t = 0.138629 \ years}[/tex]
Step-by-step explanation:
From the information we are being provided with:
The quantity P i.e [tex]P(t) = e ^{5t}[/tex]
In order to determine the time at which P = 15, we have the following:
[tex]t= t_o[/tex] when P = 15
∴ [tex]e^{5t_o} = 15[/tex]
[tex]5t_o= In (15)[/tex]
[tex]t_o = \dfrac{1}{5}In 15[/tex]
[tex]t_o = \dfrac{1}{5} \times 2.70805[/tex]
[tex]{t_o = 0.54161 \ years}[/tex]
Hence, the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
In order to determine the time at which P = 20, we have the following:
[tex]t= t_1[/tex] when P = 20
∴ [tex]e^{5t_1} = 20[/tex]
[tex]5t_1= In (20)[/tex]
[tex]t_1= \dfrac{1}{5}In (20)[/tex]
[tex]t_1 = \dfrac{1}{5} \times 2.9957[/tex]
[tex]{t_1 = 0.59914 \ years}[/tex]
Hence, the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
The doubling time at t = 0, mean P = 2
∴ [tex]e^{5t} = 2[/tex]
[tex]5t= In (2)[/tex]
[tex]t= \dfrac{1}{5}In(2)[/tex]
[tex]t = \dfrac{1}{5} \times0.693147[/tex]
[tex]{t = 0.138629 \ years}[/tex]
Hence, the doubling time [tex]{t = 0.138629 \ years}[/tex]

What could be the actual number of adults who said that they play football?d. Among the 2302 respondents, 272 said that they only play hockey. what percentage of respondents said that they only play hockey?
Answer:
(a) The exact value that is 33% of 2302 is 759.66.
(b) No, the result from part (a) could not be the actual number of adults who said that they play basketball.
(c) The actual number of adults who said that they play basketball is 760.
(d) 11.82% of respondents said that they only play hockey.
Step-by-step explanation:
We are given that a polling company reported that 33% of 2302 surveyed adults said that they play basketball.
(a) The exact value that is 33% of 2302 is given by;
[tex]33\% \text{ of } 2302[/tex] = [tex]\frac{33}{100}\times 2302[/tex]
= 759.66
(b) No, the result from part (a) could not be the actual number of adults who said that they play basketball because the value in part (a) is in fractions or in decimals and the number of people can't be in fractions. It must be a whole number.
(c) The actual number of adults who said that they play basketball is 760. {As 759.66 rounded to one decimal point}
(d) It is given that among the 2302 respondents, 272 said that they only play hockey.
Percentage of respondents who said that they only play hockey is given by;
= [tex]\frac{272}{2302}\times 100[/tex] = 11.82% ≈ 12%
a) The exact value of [tex]33[/tex]% of [tex]2302[/tex] is,
[tex]=\frac{33}{100}\times 2302[/tex]
[tex]=759.66[/tex]
b) [tex]759.66[/tex] is not the actual number of adults who said that they play football as the actual number should be a whole number and not a rational number with decimal values.
c) The actual number could be a rounded one i.e. [tex]760[/tex].
d) Let [tex]272[/tex] be [tex]x[/tex]% of [tex]2302[/tex].
[tex]\Rightarrow \frac{x}{100}\times 2302=272\\\Rightarrow x=\frac{272\times 100}{2302} \\\Rightarrow x=11.8158 \ or \ 11.82[/tex]%
Therefore, [tex]11.82[/tex]% of respondents said that they only play hockey.

how many million miles are between the earth and sun ?
91 million miles (146 million km)
Lou drives at 65 mi/h. Write an expression for the number of miles that Lou drives t hours.
Answer:
The expression for the number of miles that Lou drives t hours is t*65
Step-by-step explanation:
Two quantities are directly proportional when, when one of them is multiplied or divided by a number, the other is multiplied or divided respectively by the same number. That is, the relationship between the magnitudes is direct when one magnitude increases and so does the other (or when one magnitude decreases, so does the other).
The direct rule of three is used when the problem deals with two directly proportional quantities and is used to solve proportionality problems between three known values and one unknown, establishing a proportional relationship between all of them as follows:
a ⇒ b
c ⇒ x
So [tex]x=\frac{c*b}{a}[/tex]
In this case the rule of three can be applied in the following way: if in 1 hour Lou travels 65 miles, in t hours how much distance does he travel?
[tex]distance=\frac{t*65 mi}{1 h}[/tex]
distance=t* 65
The expression for the number of miles that Lou drives t hours is t*65
To calculate simple interest, the amount of interest, I, can be found using this formula, where P is the principal, r is the interest rate, and t is time: I=Prt Which formula can be used to determine the interest rate when the other variables are known? a.) r=IPt b.)r=I/Pt c.)r=IP/t d.) r=Pt/I
Answer:
b
Step-by-step explanation:
I = Prt Solve the equation for r
I = Prt Divide both sides by Pt to get r on one side of the equation by itself
Pt Pt Cancel the P and t on right side as P/P and t/t = 1
This leaves: I = r or r = I
Pt Pt
The interest rate formula with other known variables is R=I/PT. Therefore, the correct answer is option B.
The given simple interest formula is I=PRT.
Where, P is the principal, r is the interest rate, and t is time.
Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
To calculate the interest rate:
By rearranging the formula I=PRT, we get
R=I/PT
Therefore, the correct answer is option B.
