Solution:
Let the two digits of a number be X and Y
Let the digit at 10's place = X
Let the digit at 1's place = Y
The two digit number = 10X+Y
Given that
The sum of the digits = 9
⇛ X+Y = 9
⇛X = 9-Y →→→→eqn(i)
If 9 is added to the number the digits interchanged
⇛10X+Y +9 = 10Y+X
⇛10X+Y+9-10Y-X = 0
⇛9X-9Y +9 = 0
⇛9(X-Y+1) = 0
⇛X-Y+1 = 0
⇛9-Y-Y+1 = 0
⇛10-2Y = 0
⇛2Y = 10
⇛Y = 10/2
⇛Y = 5
Now
X = 9-5 = 4
Therefore the number = 45 Ans.

Jonita determined that the distance between her apartment and the nearest hospital was more than 1,600 meters but less than 1,900 meters. Which of the following could be a reasonable estimate for
the distance between her house and the hospital?
O 1.7 x 102 meters
O 1.8 x 103 meters
O 1.7 x 10-3 meters
O 1.8 x 10-2 meters
Answer: 1.8 x 103 meters
Step-by-step explanation:
The average of the two extremes is 1,700 meters. This would be 1.7x10^3 in scientific notation. None of the four options include this number. But three stand out as total losers. We can convert the answer options to see the difference:
O 1.7 x 102 meters = 170 meters [Loser]
O 1.8 x 103 meters = 1800 meters
O 1.7 x 10-3 meters = 0.0017 meters [Loser]
O 1.8 x 10-2 meters = 0.018 meters [Loser]

What is an equation of a line that passes through the point
(0,3) and is perpendicular to the line whose equation is
y = 2x - 1?
-
Answer: y = -(1/2)x + 3
Step-by-step explanation:
y = 2x - 1
This is in the format of y=mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).
Perpendicular lines have a slope that is the negative inverse of the reference line. The slope of this reference line is 2, so the slope of a perpendicular kline will be -(1/2).
This yields the equation y = -(1/2)x + b
To find the value of b, we can use the given point, (0,3) and use these values of x and y to solve for b:
y = -(1/2)x + b
3 = -(1/2)(0) + b
b = 3
The equation of a line perpendicular to y = 2x - 1 and goes through point (0,3) is:
y = -(1/2)x + 3
How can you split 20 into 3 groups
The answer is 6 per team with 2 left over, as (6 x 3) + 2 = 20
I thought of the largest amount that could be multiplied by 3, but the product would be less or equal to 20, that's how I got 6.
Then to find the left over remaining balls that are given out I subtracted 20-18 = 2.

Find the value of each variable in the given figures
Answer:
q = 22
Step-by-step explanation:
(7q - 46)° + (3q+6)° = 180 (linear pair property)
7q - 46 + 3q + 6 = 180
10q - 40 = 180
10q = 180 + 40
10q = 220
q = 220/10 = 22
m∠ABD = (7q - 46)° = 7(22) - 46 = 154 - 46 = 108°
m∠DBC = (3q + 6)° = 3(22) + 6 = 66 + 6 = 72°

Solve V = twh for w.
Answer:
w = V/lhStep-by-step explanation:
Given equation:
V = lwhSolve for w:
V/lh = lwh/lh Divide both sides by the lh to isolate the wV/lh = w Cancel same variablesw = V/lh Swap left and right sidesAnswer:
V/lh
Step-by-step explanation:
Given,
V = lwh
Here we know
V = volume
l = length
w = width
h = height
Now,
On solving for w
V = lwh
V = l × w × h
V/l = w × h
V/l × h = w
V/lh = w

====================================================
Explanation
x = measure of angle 1
y = measure of angle 2
x = 2y+18, since angle 1 is 18 more than twice that of angle 2
Assuming this is a parallelogram, the adjacent angles are supplementary. So,
x+y = 180
2y+18+y = 180
3y+18 = 180
3y = 180-18
3y = 162
y = 162/3
y = 54
This leads to,
x = 2y+18
x = 2*54+18
x = 108+18
x = 126
Note that x+y = 126+54 = 180
Another useful fact about parallelograms is that the opposite angles are the same measure. So angle 1 = angle 3 = 126 degrees
The measure of angle 3, if The measure of ∠1 is 18 more than twice the measure of ∠2 is 126°
What is polygon?
In geometry, a polygon is any closed curve made up of a collection of continuous line segments (sides) without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons are the three simplest polygons (five sides).
Given:
The measure of angle 1 = 2 × The measure of the angle 2 + 18
Write an equation for the above statement,
x = 2y + 18
Here, x is a measure of angle 1 and y is the measure of angle 2,
As you can see from the figure it is a parallelogram then,
x + y = 180 (The sum of supplementary angle)
Solve the equation by elimination method,
y = 54, x = 2 × 54 + 18 = 126
The opposite angle of a parallelogram are equal,
Measure of angle 3 = Measure of angle 1 = 126

how to find parallelogram height with angles and side length
Answer:
h = a * sin α
Step-by-step explanation:
The easiest answer is utilizing Law of Sines: a / Sin A = b / Sin B = c /Sin C
a and ∠α : known
∠AEB = 90°
a / Sin 90° = h / Sin α .. Sin 90° = 1
h = a * sin α
The swimming team has competed in 45 races this season. They have won 30 races so far. How many races will the team need to win today for the team to have a 75% success rate? 8 10 12 15.
The number of races the team need to win today for the team to have a 75% success rate is 15
Number of attempt = 45
Number of winnings = 30
Percentage won so far = 30/45 × 100
= 66.67%
let
x = Number of races that tfe team needs to win to have 75% success rate
(30 + x) / (45 + x) = 0.75
Cross product
30 + x = 0.75(45 + x)
30 + x = 33.75 + 0.75x
x - 0.75x = 33.75 - 30
0.25x = 3.75
x = 3.75 / 0.25
x = 15
Therefore, the number of races the team need to win today for the team to have a 75% success rate is 15
