Step-by-step explanation:
Answer:
1.392 x 10⁹ m
Step-by-step explanation:
when you put numbers in scientific notation, there is one (1) non-zero number before the decimal
1.392
now count how many place you would have to move the decimal to the right in order to make 1,392,000,000
9 place
this means your second half looks like x 10⁹
now put it all together

solve using substituion -5x + y = -2 -3x + 6y = -12
Answer:
x = 0y = - 2Step-by-step explanation:
-5x + y = -2………… Equation 1
-3x + 6y = -12 ………… Equation 2
Using substitution
Make y the subject in equation 1 and substitute it into equation 2 and solve for x
That's
y = 5x - 2
We have
- 3x + 6( 5x - 2) = - 12
- 3x + 30x - 12 = - 12
27x = - 12 + 12
27x = 0
Divide both sides by 27
x = 0
Substitute x = 0 into y = 5x - 2
We have
y = 5(0) - 2
y = - 2
So the solutions are
x = 0 y = - 2Hope this helps you

Albert and John are partners in a Bakery store. They needed $70,000 to start the business. They
invested in the ratio 3:7, respectively. How much did Albert invest in the business? How much did John invest in the business?
Answer:
Albert invested 21,000 and John invested 49,000 :)
Answer:
A: $21,000J: $49,000Step-by-step explanation:
The number of "ratio units" in their investment ratio is 3+7 = 10. Albert's investment was 3/10 of the total, so was $21,000. John invested the remaining amount, $49,000.
Albert invested $21,000; John invested $49,000.

The table shows the distance, y, a cheetah can travel in feet in x seconds. Speed of a Cheetah Time, x (seconds) Distance, y (feet) 5 470 10 940 15 1,410 20 1,880 25 2,350 Based on the information in the table, which equation can be used to model the relationship between x and y? A. y = 5x B. y = x + 5 C. y = x + 470 D. y = 94x
Answer:D y=94x
Step-by-step explanation:
First dive y and x
Then you multiply the next x and the number that you got.
ALSO I GOT IT RIGHT
D. y = 94x. will be the equation that can be used to model the relationship between x and y.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Given, a table is attached below.
Since The data in the table is showing the proportionality feature.
the property of having suitable proportions in terms of size, number, degree, harshness, etc. If a defensive action against an unfair attack results in destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Thus,
The ratio of distance and time for the cheetah = 470/5 or 940/10 or 1410/15
Since the time is denoted by "x" (in seconds) and distance is denoted by "y".
So,
y/x = 470/5
y = 94x
therefore, the equation that can be used to model the relationship between x and y will be D. y = 94x.

The two main components ofa stereo system are a radio and a speaker (ignore all other components). The lifetime of the radio is exponentially distributed with mean of 1000 hours and the lifetime of the speaker is exponentially distributed with mean of 500 hours, independent of theradio’s lifetime. What is the probability that system’s failure is due to the radio?
Answer:
the probability that system’s failure is due to the radio = [tex]\dfrac{1}{3}[/tex]
Step-by-step explanation:
From the question given;
Let the mean lifetime of the radio [tex]\dfrac{1}{\lambda_1} = 1000[/tex] and the mean lifetime of the speaker [tex]\dfrac{1}{\lambda_2} = 500[/tex]
we can re-write both expressions as:
[tex]\lambda_1= \dfrac{1}{1000}[/tex] and [tex]\lambda_2= \dfrac{1}{500}[/tex]
Let consider [tex]X_1 \ and \ X_2[/tex] to be the variables which are independent to the exponentially distributed mean of [tex]\dfrac{1}{\lambda _1} \ and \ \dfrac{1}{\lambda _2}[/tex]
∴
[tex]P(X_1< X_2) = \int ^{\infty}_{0} \ P (X_1<X_2|X_1 =x) \lambda_1 e^{-\lambda_1 \ x} \ dx[/tex]
[tex]P(X_1< X_2) = \int ^{\infty}_{0} \ P (X_1<X_2) \lambda_1 e^{-\lambda_1 \ x} \ dx[/tex]
[tex]P(X_1< X_2) = \int ^{\infty}_{0} \ e^{-\lambda_2 \ x} \lambda _1 \ e^{-\lambda_1 \ x} \ dx[/tex]
[tex]P(X_1< X_2) = \int ^{\infty}_{0} \lambda _1 \ e^{(-\lambda_1 +\lambda_2)} \ dx[/tex]
[tex]P(X_1< X_2) = \dfrac{\lambda_1}{\lambda_1 + \lambda_2}[/tex]
replace the values now; we have:
[tex]P(X_1< X_2) = \dfrac{\dfrac{1}{1000} }{\dfrac{1}{1000} + \dfrac{1}{500}}[/tex]
[tex]P(X_1< X_2) = \dfrac{\dfrac{1}{1000} }{\dfrac{1+2}{1000} }[/tex]
[tex]P(X_1< X_2) = \dfrac{\dfrac{1}{1000} }{\dfrac{3}{1000} }[/tex]
[tex]P(X_1< X_2) = {\dfrac{1}{1000} } \times {\dfrac{1000}{3}[/tex]
[tex]P(X_1< X_2) = {\dfrac{1}{3} }[/tex]
Thus, the probability that system’s failure is due to the radio = [tex]\dfrac{1}{3}[/tex]

Answer:
z = 8
Step-by-step explanation:
First, distribute:
6z = 3z + 24
Then, we subtract 3z on both sides:
3z = 24
Finally, we divide 3 on both sides:
z = 8
Hope this helps ^^
Answer:
8
Step-by-step explanation:
First distribute the 3 inside the parenthesis.
6z=3z+24
Subtract 3z to both sides
3z=24
Divide each side by 3

Does anybody know this?
Answer:
23
Step-by-step explanation:
So you want to add 7x degrees and (x-4) degrees. And it will be 8x - 4 = 180 degrees because it's 180 degrees in a straight line. And you want to + the 180 by 4 because there is -4 on the other side. so it will be 8x = 184 and you just divide 184 by 8 and it will be 23 easy. if you want to my help again you can text me on instargram jason_lee093

He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The scale is
0.5 cm = 1 inch
Multiply both sides by 2 to get
1 cm = 2 inches
To convert from the scale drawing to the actual dimensions, we will multiply by 2.
The scale length is 2.5 cm, which converts to 5 inches after multiplying by 2.
The scale width is 4.75 cm which converts to 9.5 inches after multiplying by 2.
The 2.5 cm by 4.75 cm flag on paper corresponds to a 5 inch by 9.5 inch flag in real life.

Give the vertex form and factored form of f(x)=x^2-12x+35.
What specific information does
each form provide?
Answer:
f(x)=(x-5)(x-7)
(x-6)²-1²
Step-by-step explanation:
Given:
Equation:
f(x)=x²-12x+35
Find:
Factories
Vertex form
Computation:
Factories
f(x)=x²-12x+35
f(x)=x²-(5+7)x+35
f(x)=x²-5x-7x+35
f(x)=x(x-5)-7(x-5)
f(x)=(x-5)(x-7)
So,
x = 5 , x = 7
Vertex form
By middle term divide by 2
12/2 = 6
So,
x²-12x+6²+35-6²
(x-6)²-1²
