Answer:
X=3
Step-by-step explanation:
Since all the sides of a square are equal, hence;
5x-2 = x+10
Collect like terms
5x-x = 10+2
4x =12
X = 12/4
X =3
Hence the value of x is 3

How would you decide whether or 5 or 595 is greater?
Answers
So let’s analyze both numbers-
595 is a 3 digit number meaning it goes up to
the “hundred” place.
5 is a 1 digit number meaning it only goes up to the “ones” place.
From there you should be able to tell the greater number.
Answer:
Well, the number 595 is exceptionally larger. You would be able to tell by simply subtracting 595 and 5 and you would get 590 leaving you with answer. 595 is greater
Step-by-step explanation:
A philanthropic organization helped a town in Africa dig several wells to gain access to clean water. Before the wells were in place, an average of 120 infants contracted typhoid each month. After the wells were installed, the philanthropic organization surveyed for nine months and found an average of 90 infants contracted typhoid per month. Assume that the population standard deviation is 40 and the number of infants that contract typhoid is normally distributed. Specify the null and alternative hypotheses to determine whether the average number of infants that contract typhoid has decreased because the wells were put in place.
Answers
Answer:
H0 : μ = 120
H1 : μ < 120
We Can conclude that the number of infants that contract typhoid has reduced because the wells were put in place.
Step-by-step explanation:
Average Number of infants who contracted typhoid monthly = 120
Average Number of infants who contracted typhoid monthly after well installation = 90
The null and alternative hypothesis :
H0 : μ = 120
H1 : μ < 120
Obtain the test statistic :
(Xbar - μ) ÷ s/sqrt(n)
(90 - 120) ÷ 40/sqrt(9)
-30 ÷ 13.3333
= - 2.25
The Pvalue at 95% confidence, df = n-1 = 9 - 1 = 8
Tcritical at 95%, df = 8 ; one tailed = 0.02728
Decision region :
Pvalue < α ; Reject H0
0.02728 < 0.05 ; Hence, we conclude that there is significant evidence that the average number of infants that contract typhoid has decreased because the wells were put in place.

plug in 1,2, and 3 into the part of the equation "n".
Answer:
a1 = -7
a2 = - 13
a3 = - 19
Step-by-step explanation:
n = 1
a1 = 2*(-3)*1`- 1
a1 = -6 - 1
a1 = - 7
n=2
a2 = 2(-3)*2 - 1
a2 = -12 -1
a2 = - 13
n3 = 2(-3)*3 - 1
n3 = -18 - 1
n3 = -19

A positive angle less than 360 that is coterminal with -725 degrees is
Answers
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.

write an equation for the nth term of the arithmetic sequence. Then find a40.
1/4,1/2,3/4,1,...
Answers
Answer:
The nth term is: [tex]a_n = \frac{1}{4} + \frac{1}{4}(n-1)[/tex]
a40 = 10
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The nth term of a sequence is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference.
1/4,1/2
This means that:
[tex]d = \frac{1}{2} - \frac{1}{4} = \frac{2}{4} - \frac{1}{4} = \frac{1}{4}[/tex]
1/4
This means that [tex]a_1 = \frac{1}{4}[/tex]
The nth term is:
[tex]a_n = a_1 + (n-1)d[/tex]
[tex]a_n = \frac{1}{4} + \frac{1}{4}(n-1)[/tex]
Then find a40.
[tex]a_{40} = \frac{1}{4} + \frac{1}{4}(40-1) = \frac{1}{4} + \frac{39}{4} = \frac{40}{4} = 10[/tex]
So
a40 = 10

24.. A toy company makes 40 plastic harmonicas in 30 minutes. At this
rate how long will it take to make 200 harmonicas?
Proportions
Answers
Answer:
It will take 2 and a half hours
Step-by-step explanation:
Well 40 can go into 200 5 times so you would do 5 times 30 minutes which would be 150 minutes and then you would divide it by 60 to simplify which would be 2 hours and 30 minutes. So it will take 2 and a half hours to make 200 harmonicas.
200/40 = 5
5 * 30 = 150
150/60 = 2 hours and 30 minutes
Answer:
6.7 minutes
Step-by-step explanation:
From what we know, we will have to divide. The things we are dividing are the 30 minutes it took to make the 40 plastic harmonicas and the total we need of harmonicas, which is 200. By dividing 200 by 30, we get 6.666666666666667. But, we can't have that long answer, so we need to round up. Which is when we get our quotient of 6.7 minutes.
