The geometric mean of a number and nine times the number is 30. What is the number?
For the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.
As given in the question,
Geometric mean GM = 30
Let us assume the first number is x
and second number i.e. 9 times of the first number is 9x
By the formula GM = [tex]\sqrt{x.y}[/tex]
Now putting the value
30 = [tex]\sqrt{x.9x}[/tex]
30 = [tex]\sqrt{9x^{2} }[/tex]
30 = 3x (∴ square root of 9 is 3 and sq root of x² is x)
10 = x (by dividing both the side by 3)
Therefore, for the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.

The value of angle 5 is 115°
What are corresponding angles?Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal).
angle 2 is 65°
angle 6 = angle 2 = 65°( corresponding angles)

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 90(1.02)
The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.
y = 90(1.02)^x
The general form equation is:
y(x)= a(1+r)^x such that r is the decay percent.
on comparing,
1 + r = 1.02
r = 1.02 - 1
r = 0.02
converting into percent
r = 0.02 * 100
r = 2%.
Hence the exponential growth is 2%.

Is perpendicular to KL.

1. The length of RS is 5.
2. The length of JK is 6.
3. The length of RT is 4.
4. The perimeter of triangle JKL is 24.
What do you mean by right angle triangle?
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
According to data in the diagram of the given question:
We have :
The ΔJKL, ΔRKS and ΔRTS are right-angle triangle.
The length of RK=3 and KS=4
We are using pythagoras theorem for determine the length of RS,
(RK)²+(KS)²=(RS)²
(3)²+(4)²=(RS)²
9+16=(RS)²
25=(RS)²
(5)²=(RS)²
RS=5
∴ The the length of RS is 5.
Now, we need to find the length of JK,
JK=2(RK)=2(3)=6
JK=6 [Because RK is midpoint of the side JK]
We have given value of KS=4 and the side KS is the opposite side of RT,
So, that's why the value of RT=4.
Now, we will find the perimeter of ΔJKL,
JK=6, KL=8 and we need to find the side JL,
(JK)²+(RL)²=(JL)²
(6)²+(8)²= (JL)²
36+64=(JL)²
100=(JL)²
(10)²=(JL)²
JL=10
The perimeter of the triangle ΔJKL,
Perimeter=6+8+10=24
Therefore, the perimeter of the triangle is 24.

. a trough has ends shaped like isosceles triangles, with width 3 m and height 4 m, and the trough is 10 m long. water is being pumped into the trough at a rate of 5m3/min. at what rate does the height of the water change when the water is 1 m deep?
The rate at which the height of the water changes when the water is 1m deep is; dh/dt = 1.5m/min
We are given;
width; w = 3m
Height; h = 4m
Length of trough; L = 10m
According to similar triangle property; w =3/4h
volume of water; V = 1/2×w×h×L = 1/2 × 3/4h × h × 10 = 15/4 h²
Differentiate using chain rule for both sides with respect to t gives;
dV/dt = (1/2)(15/2)h(dh/dt).
Now, we are given dV/dt = 5m³/min and we want to find the rate at which the height of water changes when the water is 1 m deep.
Thus;
5 = ×dh/dt
At h = 1m; 5 = 15(1)/2 × dh/dt
⇒ dh/dt = 2/3
dh/dt = 1.5 m / min

In a recent student government election the ratio of students who voted for the winner to all the students who was 0.70 to the number of students who wrote it was 75 how many votes did the winner get?
The winner received 53 of the 75 votes in the student gov. election according to provided ratio.
What is ratio?
In arithmetic, a magnitude relation shows range times one number contains another.
Main body:
Because the ratio of students who voted for the winner compared to all students who voted is 0.70
we can rewrite this as:
0.70 = 70/100
And, because we know the total number of students who voted is 75 and if we call the number of students who voted for the winner s , we can then write this relationship and solve for s :
[tex]\frac{70}{100} = \frac{s}{75}[/tex]
Multiplying both sides by 75.
75*[tex]\frac{70}{100} = \frac{s}{75}[/tex]*75
s= 75*70/100
s = 5250/100
s = 52.5
s ≈ 53.
Hence ,The winner received 53 of the 75 votes.

3. 27 is 30% of 90.
Explain percentage.A percentage is a particular number or fraction in every hundred. The denominator of the fraction is 100, and it is represented by the symbol "%."
The purpose of percentage calculations is to determine the percentage of a whole in terms of 100. A percentage can be determined using one of two methods:
Through the unitary approach.By making 100 the new denominator of the fraction.It should be noted that when the denominator is not a power of 100, the second technique of percentage computation is not used.
Given, a comb has 90 teeth.
1. Find out what percentage of 90 is 90 now.
Let the percentage be x,
(x/100) × 90 = 90
x = (90 × 100)/90
x = 100 %
2. Now, find what percent of 90 is 9.
Let the percentage be x,
(x/100) × 90 = 9
x= (9 × 100)/ 90
x = 10%
3. Now, find what percent of 90 is 27.

one day is the amount of time it takes for a planet to make one complete rotation. The number of hours in one day is different for each planet. How many days are equal to 1,100 hours on Saturn? What do you need to do to solve the problem
A) 1,100 hours is equal to approximately 104days in Saturn.
B) You need to know how hours make 1day in Saturn. i.e 10 hours 34minutes or 10.567hours.
From the question note that the number of hours in one day is different for each planet.
Hence for Saturn;
1 day = 10hours.34minutes
X day =1,100 hours
Note; 34 minutes in hours will be:
60 minutes =1hour
34/60 =0.567hour
Thus;
10hours.34minutes = 10hours +0.567hour
=10.567hours
To find the number of days in 1,100 hours, we cross multiply;
X day * 10.567hours =1,100 hours * 1 day
X day = 1,100 hours * 1 day
10.567hours
X day =104.1 ≈ 104 days
Therefore, you need to know the number of hours that makes a day in Saturn.i.e 10 hours 34minutes or 10.567hours.
. Again, 1,100 hours is equal to approximately 104days in Saturn.

Which equation represents a line which is perpendicular to the line y=2x-5y
A. 2x−y=−4
B. 2y−x=4
C. x+2y=-6
D.2x+y=-2
Answer:
c
Step-by-step explanation:
To find a perpendicular line, you must compare the slopes. With the equation y=2x-5, we're looking for the inverse/opposite slope of -1/2.
Option A still has a slope of 2. Option B, when everything is in the format of mx+b = y format is -x-4=-2y. which gives us 1/2 but not -1/2. C when everything is on the right side gives us -2y=x-6. Divide both sides by -2 to get the y by itself and you're left with y = -1/2x+3. Now we found the equation that gives us the -1/2 slope we were looking for.
