What is the value of x in the following proportion? 7/x-5 = 15/x+4

1 answer:

Shalnov [3]3 years ago

For this question you should first add -15/x on both sides of the equation and then add +5 on both sides:
7/x - 15/x = 5 + 4
-8/x = 9
so now you can multiply both sides by x:
-8 = 9x
now you should divide both sides by 9:
-8/9 = x :)))
I hope this is helpful

Find a1 if Sn = 89,800, r = 3.4, and n = 10. Round to the nearest hundredth if necessary.

xxMikexx [17]

Answer:

$a_1=1.04$

Step-by-step explanation:

We have a geometric sequence with:

$Sn = 89,800$ , $r = 3.4$ , and $n = 10$

Where

Sn is the sum of the sequence

r is the common ratio

$a_1$ is the first term in the sequence

n is the number of terms in the sequence

The formula to calculate the sum of a finite geometric sequence is:

$S_n=\frac{a_1(1-r^n)}{1-r}$

Then:

$89,800=\frac{a_1(1-(3.4)^{10})}{1-3.4}$

Now we solve for $a_1$

$89,800(1-3.4)=a_1(1-(3.4)^{10})$

$a_1=\frac{89,800(1-3.4)}{1-(3.4)^{10}}\\\\a_1=1.04$

What measure of center best represents the data set? Drag and drop the correct answer into the box. Data Set Best Measure of Cen

ella [17]

The measure of center best represents the data set is Mean or Median.

Given

Data Set Best Measure of Center {27, 29, 26, 28, 25}.

<h3>What is the mean of the data set? </h3>

The mean is the average of a set of data.

The mean is found by finding the sum of the data and then dividing the sum by the number of data.

<h3 />

The mean of the given data set is;

$\rm Mean = \dfrac{27+29+26+28+25}{5}\\\\Mean =\dfrac{135}{5}\\\\Mean =27$

Arranging the data set in the ascending order

{25, 26, 27, 28, 29}

The median is defined as the middle value of the given data set.

The median of the data set is 27.

Hence, the measure of center best represents the data set is Mean or Median.

The radius of a circle is (7x+3)cm. Write an expression to represent the area of the circle in simplified form

zepelin [54]

Answer:

A = π(7x + 3)² cm²

Step-by-step explanation:

A = πr² is the appropriate equation. If r = 7x + 3 cm, then the area of this particular circle is:

A = π(7x + 3)² cm²

Find the midpoint of the line segment with end coordinates of: ( 2 , 1 ) and ( 4 , 5 )

Valentin [98]

Step-by-step explanation:

x1=2. y1=1. x2=4. y2=5

by midpoint formula,

2+ 4/2 = 6/2 =3

1+5 /2 =6/2 = 3

therefore,the midpoints are (3,3)
