Answer:
24
Step-by-step explanation:
Original Number :-
Given that ,
Sum of digits is 6 .Let ,
Tens place = x Units place = 6 - xNumber ,
10x + 6 - x = 9x + 6On interchanging the digits :-
Tens place = 6-x Units place = x→ Number = 10( 6-x) + x
→ Number = 60 - 10x + x
→ Number = 60 - 9x
According to Question,
→ 9x + 6 + 18 = 60 - 9x
→ 18x = 60 - 24
→ 18x = 36
→ x = 36/18
→ x = 2
N = 9x + 6 = 18+6 = 24 Hence the required answer is 24.what is the constant rate change shown in the graph below?
Answer:
the two points be
(0,0) and (1,-3)
slope [m]=[-3-0]/[1-0]=-3
constant rate is-3.
PLEASEEE HELP ME FIND THE SURFACE AREA
Will mark brainliest!!
Answer:
100.48
Step-by-step explanation:
Surface area of a cylinder = [tex]2\pi r^2+2\pi rh[/tex]
Where r = radius and h = height
We are given the diameter ( 4 cm ) and the height ( 6cm )
To convert diameter to radius we simply divide by 2 ( because radius = half the length of the diameter )
4 / 2 = 2 Thus, r = 2
Now we plug in the values of the radius and height into the surface area of a cylinder formula ( note we must use 3.14 for π as the question says to. not doing so can result in a wrong answer )
[tex]SA=2(3.14)(2^2)+2(3.14)(2)(6)\\2^2=4\\4*3.14=12.56\\12.56*2=25.12\\\\2*3.14=6.28\\6.28*2=12.56\\12.56*6=75.36\\\\75.36+25.12=100.48\\SA=100.48cm^2[/tex]

Answer:
20%
Step-by-step explanation:
Probability is always expressed as a part of a whole, thereby in fractions or percentages. From the statistics gathered, it said that 80% of the time, the plane arrives right on schedule in El Centro. That means that the probability of NOT arriving on time is the other portion, which is 20%. The answer is 20%.
Which terms are like terms?
4c, 2, 6f, -5, and 7c
Answer:
2 and -5
4c and 7c
Step-by-step explanation:
2 and -5 have no coefficient
4 and 7 have the same coefficient which in this case is c.
therefore the two pairs are like terms.

Step-by-step explanation:
By the Triangle Midsegment Theorem, the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. Therefore, (1/2)FH ≡ IH, (1/2)HG ≡ HJ. Knowing that IJ = 8 gives you the presidence to solve for the perimeter.

A telephone pole casts a shadow that is 12 feet long. At the same time, a man standing nearby who is 6 feet tall casts a shadow that is 2 feet 4 inches long. How tall is the
telephone pole to the nearest foot?
The telephone pole is feet tall
Answer:
31 feets
Step-by-step explanation:
Given that :
Telephone shadow Ts = 12 feets
Man's height, Mh= 6 feets
Man's shadow, Ms = 2 feets 4 inches
Height of telephone, Th =?
Recall :
1 foot = 12 inches
x foot = 4 inches
12x = 4
x = 4/12 = 1/3 inches
Hence, man's shadow = 2 1/3 feets =
Using cross multiplication :
Mh / Ms = Th / Ts
6 / 7/3 = Th / 12
6 / 2.33333 = Th / 12
12 * 6 = 2.33333 * Th
72 = 2.33333 Th
Th = 72 / 2.333333
Th = 30.85
Height of telephone pole = 31 feets

in new england 47% of the houses have a garage and 36% of the houses have a garage and a backyard what is the probability that a house has a backyard given that has a garage probs and stats
Answer:
The probability that a house has a backyard given that has a garage is 76.60%.
Step-by-step explanation:
Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:
47 = 100
36 = X
(36 x 100) / 47 = X
3,600 / 47 = X
76.5957 = X
Therefore, the probability that a house has a backyard given that has a garage is 76.60%.
Garnet has a container with 15 1/2 cups of flour in it. She can make one dozen muffins with 2 1/2 cups of flour. How many dozens
of muffins can Garnet make with the flour she had?
Answer:6 1/5
Step-by-step explanation:
Lets start by saying that one dozen is 12 and not a bakers dozen (13)
We will first see how many times 2 1/2 can go into 15 1/2 by dividing the two
[tex]15\frac{1}{2} /2\frac{1}{2}=6\frac{1}{5}[/tex]
then we can verify by multiplying 2 1/2 and 6 1/5
[tex]2\frac{1}{2} *6\frac{1}{5} =15\frac{1}{2}[/tex]

What is the tenth term of the sequence described by the rule?
A(n)=−9+5(n−1)
Answer:
46
Step-by-step explanation:
Replace n by 10 in the rule a(n) = -9 + 5(n - 1):
a(10) = -9 + 5(9) = 45 - 9 = 46
2 x – 5y = –47
6 x – 5y = –71
Answer: x = - 6
y = 7
Step-by-step explanation:
Let 2x -5y = -47 be eq. 1
And 6x -5y = -71 be eq. 2
By substrate of 1 - 2:
2x-5y-6x+5y = -47+71
so -4x=24 and x= -6
Substitute x in any eq.
2(-6) - 5y = -47
-5y = -47 +12
-5y = -35 so y= 7
Find the measure of the exterior angle.
Step-by-step explanation:

Decreasing: [tex](0, 1)[/tex]
Concave Up: [tex](0, \infty)[/tex]
Concave Down: [tex](-\infty, 1)[/tex]
Step-by-step explanation:
Increasing intervals are intervals where the function is approaching positive infinity (upwards). Decreasing intervals are intervals where the function is approaching negative infinity (downwards). Concavity refers to intervals that resemble a parabola either opening upwards (Concave Up) or opening downwards (Concave Down).

A ball moves in a straight line has an acceleration of a(t) = 2t + 5. Find the position function of the ball if its initial velocity is -3 cm per second and it’s initial position is 12 cm.
Answer:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is [tex]a(t) = 2t + 5[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K[/tex]
In which K is the constant of integration, which is the initial velocity. So K = -3 and:
[tex]v(t) = t^2 + 5t - 3[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K[/tex]
In which K, the constant of integration, is the initial position. Since it is 12:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
