Answer:
x = 3
y = 1
Step-by-step explanation:
x= 5-2y
6x + 11y = 29
6( 5 - 2y ) + 11y = 29
30 - 12y + 11 y = 29
-y = -1
y = 1
x + 2y = 5
x = 5 - 2y
x = 5 - 2
x = 3

One rectangle measures 2 units by 7 units. A second rectangle measures 11 units by 37 units. Are these two figures scaled versions of each other? If so, find the scale factor.
Answer:
No.
Step-by-step explanation:
If they are scaled versions of each other then the ratio of corresponding sides would be equal.
11/2 = 5.5
37/7 = 5.29
So they are not scaled versions
Answer:
no

16/30=20/x what is x?
Answer: 75/2
Step-by-step explanation: Math
Answer:
75/2
Step-by-step explanation:
16/30=20/x
Cross multiply
16*x=(20)*(30)
16x=600
Divide both sides by 16.
16x /16 = 600 /16
x=75/2

month later, you get the guitar back by paying the pawnbroker $1170. What annual interest rate did you pay?
You will pay a simple interest rate of %
(Round to the nearest whole number as needed.)
Answer:
51% (596.7) or 52% (608.4)
Step-by-step explanation:
1170 multiply by 51% or 52% and you will get as close as you can to 600. I hope this can help. I am sorry If I got it wrong or misunderstood. :) Have a nice day!
An airline tracks data on its flight arrivals. Over the past six months, 65 flights on one route arrived early, 273 arrived on time, 218 were late, and 44 were cancelled. What is the probability that a flight is early
Answer:
0.108
Step-by-step explanation:
Given that:
Number of flights reached early = 65
Number of flights reached on time = 273
Number of flights reached late = 218
Number of flights canceled = 44
To find:
The probability that a flight is early.
Solution:
First of all, let us have a look at the formula for probability of an event E.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, Event E is that the flight is early.
Number of favorable cases is equal to the number of a flights which reached early i.e. 65
Total number of cases is the total number of flights.
i.e. 65 + 273 + 218 + 44 = 600
So, the required probability is:
[tex]P(E) = \dfrac{65}{600} = \bold{0.108}[/tex]

Answer:
16% of the Students
Step-by-step explanation:
[tex]\frac{124}{775} * \frac{x}{100} \\124 * 100 = 12400\\12400 / 775 = 16\\x = 16\\\frac{124}{775} *\frac{16}{100} \\[/tex]
The rabbit population in a certain area is 200% of last year's population. There are 300 rabbits this year. How many were there last year?
Answer:
There were 650 rabbits last year
The percentage of a quantity can be found by first changing the percent into a fraction and then multiplying it to the value of that quantity. Last year the number of rabbits was 150.
What is percentage?A percentage is a value that indicates the hundredth part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The population of rabbit this year is 300.
The percentage of the population with respect to the last year is 200%.
Suppose the population of rabbits last year was P.
Then as per the question, following expression can be written,
200% of N = 300
⇒ (200 / 100) × N = 300
⇒ 2N = 300
⇒ N = 150
Hence, the population of the rabbits last year was 150.

JULIO'S DAD BOUGHT 10 DOZEN POTATOES. THE POTATOES WERE EQUALLY
DIVIDED INTO 6 BAGS. HOW MANY POTATOES ARE IN EACH BAG?
Answer:
There are 20 potatoes in each bag.
Step-by-step explanation:
There are 12 in a dozen. 10 dozens equal 120.
120 ÷ 6 = 20.
20 potatoes in each bag.
Hope this helped!
Answer:
there are 20 potatoes in each bag.
Step-by-step explanation:
One dozen is equal to 12, so you have to multiply 12 by 10 to find the number of potatoes Julio's dad bought.
12 x 10 = 120
after finding the number of potatoes bought, you have to divide the number of potatoes by the number of bags:
120 : 6 = 20

Suppose 56V% of politicians are lawyers. If a random sample of size 787787 is selected, what is the probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4%4%
Answer: 0.0238
Step-by-step explanation:
Given : Proportion of politicians are lawyers: p= 0.56
Sample size : n= 787
Let [tex]\hat{p}[/tex] be th sample proportion.
The the probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4% will be :-
[tex]P(|\hat{p}-0.56|>0.04)=P(-0.04>\hat{p}-0.56>0.04)=\\\\ P(-0.04+0.56>\hat{p}>0.04+0.56)\\\\=P(0.52>\hat{p}>0.60)\\\\=P(\dfrac{0.52-0.56}{\sqrt{\dfrac{0.56(1-0.56)}{787}}}>\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.60-0.56}{\sqrt{\dfrac{0.56(1-0.56)}{787}}})\\\\=P(-2.26>z>2.26)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(-2.26<z<2.26)\\\\=1-(2P(Z > 2.26)-1)\ \ \ [P(-z<Z<z)=2P(Z > |z|)-1]\\\ =2-2P(Z > 2.26)\\\\=2-2(0.9881)=0.0238[/tex]
Hence, the required probability = 0.0238

Solve tan 2x + tan x=0, for 0 < x < 2π
Answer:
Start by getting everything on the same side of the equals sign and then set it equal to 0. . Factor out the common tan^2x like this: . Now we have 2 separate equations to solve: and sinx = 0. Now we have to figure out where tan^2 is 0 between 0 and 2pi. If we include 2pi, the solutions for that equation are . You can test those out on your calculator just to be sure. There's only one value of x for the next equation. The only place between 0 and 2pi where the sin x = 1 is at x = . And there you go!

Write the equation for a line that passes through (5,-4) and is perpendicular to the
linear function 2x - 10y = 0
Answer:
y = -5x -24
Step-by-step explanation:
Given parameters:
Coordinates of the line = (5, - 4)
Linear function ;
2x - 10y = 0
Solution:
The equation of the line perpendicular to this line will have a slope that is the a negative inverse of the given line;
2x - 10y = 0
Equation of a line is given as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
We find the slope and y-intercept of the new line;
From: 2x - 10y = 0
Rewrite;
-10y = -2x
y = [tex]\frac{-2}{-10}[/tex]x
y = [tex]\frac{1}{5}[/tex]x
The slope of this line is [tex]\frac{1}{5}[/tex] , the line perpendicular will have slope of -5
For the new line;
y = mx + c
let us find c;
-4 = -5( -4) + c
-4 = 20 + c
c = -20 - 4
c = -24
The equation of the perpendicular line is;
y = -5x -24
