Answer:
845 miles
Step-by-step explanation:
First let us find the speed ( rate ) using the below formula.
[tex]\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}[/tex]
[tex]\sf Speed=\frac{585 \:miles}{9 \:h}[/tex]
[tex]\sf Speed=65\:miles\: per\: hour[/tex]
They also said that, at the same speed he traveled for 13 hours.
So, now we have to find the distance.
For that, you can use the same formula by making the distance as the subject.
Let us find it now.
[tex]\sf Distance \:\:travellled=Speed\:*\:Time\:\:Taken\\\\\sf Distance \:\:travellled=65\:*\:13\\\\\sf Distance \:\:travellled=845 \:miles[/tex]
Describe and correct the error in solving the system of linear equations.
5 + 2y = 9
3x - 2y = -1
2x = 10
x = 5
Answer:
The second equation is incorrect!
Step-by-step explanation:
Let's break this down line by line:
y=2
x=5
1) 5 + 2y = 9 this equation is basically 5 + (2x2) = 9 meaning that y equals 2. This equation is correct!
2) 3x - 2y = -1 becomes (3x5) - (2x2) = which also basically becomes 15 - 4 which in reality equals 11. This means the equation on the second line is incorrect! Because 3x - 2y = -1 is incorrect and it is actually 3x - 2y = 11
3) 2x = 10 is correct because x=5 meaning that this equation would be 2 x 5 = 10!

The simplification of the given complex number is 4.70
What are complex numbers?Complex numbers are those numbers that contain the imaginary and the real part.
A Complex value z is written in a rectangular form as z = x+iy where (x, y) is the rectangular coordinates.
r is the modulus of the complex number and θ is the argument
r =√x²+y² and θ = tan⁻¹y/x
We need to simplify the complex number;
(30-50i)/(3-5i)
Therefore,
(30-50i)/(3-5i) x (3+5i)/(3+5i)
(30-50i) (3+5i)/(9 + 25)
90 + 150i - 150i - 250 /34
160/34

Step-by-step explanation:
A builder buys 12.4 acres of land to develop a new set of walking trails and baseball fields.
Part A
The builder plans to use 0.25 of the land for baseball fields. How many acres will the builder use for the baseball fields?
_____ acres
Part B
The builder buys a second property that has 0.6 times as many acres as the first property. How many acres of land are in the second property?
_____ acres
Please explain your steps and what you did. Thank you!
Answer:
a. 3.1 acres
b. 7.44 acres
Step-by-step explanation:
a.
0.25 can also be written as 25%
to find 25% of 12.4 do:
25/100 * 12.4 (cross multiply by 4)
= 25/25 * 3.1
= 1 *3.1
= 3.1
b.
0.6 * 12.4
= 7.44

Rewrite one tenth times x cubed times y plus two tenths times x times y squared using a common factor.
one tenth times x times y times the quantity x squared plus 2 times y end quantity
one tenth times x cubed times y squared times the quantity y plus 2 times x end quantity
one fifth times x times y times the quantity 2 times x squared plus 2 times y end quantity
one fifth times x times y times the quantity x squared plus 2 times y end quantity
Answer: The expression which can be rewritten using a common factor is; xy/10 (x² + 2y).
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We have the following information given as;
One tenth times x cubed times y plus two tenths times x times y squared using a common factor.
We know that 'times' has to be replaced with multiplication.
Now, we will change this into mathematical expression as;
x³y/ 10 + 2xy²/ 10
Now, the common factor can be ;
xy/10
The Common factor refers to the number and the variables taken as a common factor should be able to completely divide the terms given any expression.
Now, taking it as a common factor, we have the following expression:
xy/10 (x² + 2y)
Hence, the required expression is; xy/10 (x² + 2y).

Answer:
Scroll Down Below...
Step-by-step explanation:
Part A: To record an equating defining this position, we can start by canny the total distance camouflaged in d supplementary days. Since the kin drives 350 5 per epoch each surplus era, the total distance marked in d supplementary days is 350d. Adding the beginning 200 5 compelled on the first epoch, the equating enhances:200 + 350d = 1,600Part B: To resolve the equating and find the total number of days the offspring will travel, we need to detach the changeable d. We can start by subtracting 200 from two together hands of the equating:350d = 1,600 - 200350d = 1,400Next, we separate two together parts of the equating by 350 to resolve for d:d = 1,400 / 350d = 4Therefore, the kin will travel for an supplementary 4 days to reach a total distance of 1,600 5.

two lines meet at a point that is also the vertex of an angle. Set up and solve an equation to find the value of m.
Answer:The vale of m is
Step-by-step explanation:
First, we have to find the angle between 24° and 68° and let that angle be- x°
As the right angle,
90° = 68°+ x°
22° = x°
Now,
Angle m = angle x° + 24° ( vertical opposite angles)
m = 22 +24
m = 46

(2n²•n³•3n¹)²
(y•4y²)³
(4b³•b)²
(3s²•s³)²
(3r²•2r³)³
Simplify the exponents. Please show me how to do the step by step?? I'm not sure how to solve these when they have parentheses
(2n²•n³•3n¹)²
First, simplify inside the parentheses. We multiply the coefficients and exponents. The coefficients: 2×3=6. and the exponents: 2×3×1=6. All together that gives: [tex](6n^6)^2[/tex]Then multiply the inside of the parentheses by itself since it's the exponent is 2. Therefore we end with [tex]36n^12[/tex]
(y•4y²)³
Same approach. Multiply the inside which gives [tex]4y^3[/tex] Then calculate that to the power of 3.
[tex]4y^3[/tex]×[tex]4y^3[/tex]×[tex]4y^3[/tex]=[tex]64y^9\\[/tex]
(4b³•b)²
[tex]=(4b^4)^2\\=4b^4\cdot4b^4\\=16b^8[/tex]
(3s²•s³)²
[tex]=(3s^5)^2\\=3s^5\cdot3s^5\\=9s^{10}[/tex]
(3r²•2r³)³
[tex]=(6r^5)^3\\=6r^5\cdot6r^5\cdot6r^5\\=216r^{15}[/tex]
Hope that helped. Let me know if you have any further questions!
