if we subtract the didgit of a two digit number, we get 4. if we interchange the digits of the number and subtract the new number from the original number we get 44. What is the original number
Answer:
Assume that the two digits are x and y (x is at ones position and y is at tens position)
if we subtract the digit of a two digit number, we get 4.
this means,
x-y=4 ..................... (1)
if we interchange the digits of the number and subtract the new number from the original number we get 44.
this means,
old no. 10y+x
new no. 10x+y
10y+x-(10x+y)=44
10y+x-10x-y=44
9y-9x=44 ........................... (2)

Answer:
54 degrees.
Step-by-step explanation:
So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).
Given this, set these values equal to each other to get the value of a.
d = a + b
2a = (a+10)+44
2a = a + 54
a = 54
The measure of the exterior angle is 54 degrees.

When the sun is at a certain angle in the sky, a 50 foot building will cast a 20 foot shadow. What is the length of the shadow in feet cast by a 20 foot pole at the same time?
Answer:
Prepara a bar graph. (Mention the scale)
Potato= 25 per kg
Tomato= 40 per kg
Cauliflower= 10 per kg
Chilli= 15 per kg
Lemon= 30 per kg
Answer:
8 ft
Step-by-step explanation:
The height of the building/pole and shadow of each are in proportion.
let x be the length of shadow of the pole, then
[tex]\frac{50}{20}[/tex] = [tex]\frac{20}{x}[/tex] ( cross- multiply )
50x = 400 ( divide both sides by 50 )
x = 8
The shadow cast by the pole is 8 ft

A town has a population of 2000 and grows at 4% every year.
What would the exponential function be if you were trying to predict what the
town's population would be after 12 years?
A 2000(04)12
B 2000(0.4)12
C 2000(1.04)12 D 0.04(2000)12

Given the conversion factor 12/1 in over 1ft, which cube has the larger surface area?
Answer:
Solid A
Step-by-step explanation:
3 feet is 3 x 12 = 36 inches, which is less than 48 inches, so solid A has a larger surface area than solid B.

Answer:
Option DStep-by-step explanation:
The graph of a function should pass the vertical line test in order to be a function.
Option A
Fails as repeat x-values of 14 with different y-valuesOption B
Fails as repeat x-values of 15 with different y-valuesOption C
Fails as repeat x-values of 16 with different y-valuesOption D
All x-values are different so this is a functionThe rule is .
Every domain of the function should have an unique range i.e f(x)=y
#1
f(14) has two values hence not a function
#2
f(15) has two values hence not a function
#3
f(16) has two values hence not a function
#4
Yes it's a function,every domain has an unique range

f(x) = 35x + 25
g(x) = 22x + 18
f(4) is x = 4 for function f(x)
g(10) is x = 10 for function g(x)
Step 2: Find Function Values
f(4)
Substitute in x [Function f(x)]: f(4) = 35(4) + 25Multiply: f(4) = 140 + 25Add: 165g(10)
Substitute in x [Function g(x)]: g(10) = 22(10) + 18Multiply: g(10) = 220 + 18Add: g(10) = 238Step 3: Evaluate

Which values represent the independent variable? (–2, 4), (3, –2), (1, 0), (5, 5) A. {–2, 3, 1, 5} B. {4, –2, 0, 5} C. {–2, 4, 3, –2} D. {–2, –1, 0, 5}
Answer:
Option A: {-2, 3, 1, 5}
Step-by-step explanation:
A function is a relationship that maps elements from one set (the domain, set of the inputs, the independent variables) into elements from another set (the range, set of the outputs, the dependent variables ).
Such that the standard notation is (x, y)
This says that the function/relation maps the element x into the element y.
So here the independent variable is x.
Now, in a relation:
{ (x₁, y₁), (x₂, y₂), ..., (xₙ, yₙ)}
The independent variable is represented with the set:
{x₁, x₂, ..., xₙ}
then, in the relation:
(–2, 4), (3, –2), (1, 0), (5, 5)
The set that represents the independent variable is a set with the first elements from each one of these four points:
{-2, 3, 1, 5}
The correct option is A.
Write an inequality, in slope-intercept form, for the graph below. If necessary,

(-3,0)
X

(0, -3)

Given:
The graph of an inequality.
To find:
The inequality in slope intercept form.
Solution:
The slope intercept form is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\dfrac{-3-0}{0-(-3)}(x-(-3))[/tex]
[tex]y=\dfrac{-3}{3}(x+3)[/tex]
[tex]y=-1(x+3)[/tex]
[tex]y=-x-3[/tex]
From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".
[tex]y\geq -x-3[/tex]
Therefore, the required inequality is [tex]y\geq -x-3[/tex].

Answer:

Step-by-step explanation:
Hanna: 20 1/4 cups per 9 servings.
We divide 20 1/4 by 9 to find the amount per serving.
20 1/4 / 9 = 81/4 / 9/1 = 81/4 * 1/9 = 9/4
Hanna's recipe uses 9/4 cup per serving.
Pocahontas: 3/4 cup more per serving than Hanna
9/4 + 3/4 = 12/4 = 3
Pocahontas uses 3 cups per serving
3 * 8 = 24
Pocahontas uses 24 cups of flour for 8 servings.

approximate: V = 141.4 in.^3
Step-by-step explanation:
V = (pi)r^2h
r = d/2 = 6 in./2 = 3 in.
V = (pi) * (3 in.)^2 * 5 in.
V = 45pi in.^3

find the length of the diagonals of rectangle QRST
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=26
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=111
