Will a stand that can hold up to 40 pounds support a21-kilograms television? Explain. Use 2.2 lb=1kg.
Answer: No
Step-by-step explanation:
Weight limit = 40 Lb
Weight given = 21 kg
Conversion factor
2.2 Lb = 1 kg
2.2 x 21 = 46.2
46.2 Lb = 21 kg

Given lJK , which is an isosceles right triangle, IJ=4 and m
Answer:
[tex]IK = IJ\sqrt{2}[/tex]
Step-by-step explanation:
First, it's an isosceles right triangle, which means there is a 90 degree angle and the two other angles are equal.
To find what the two other angles are, you can set up a quick equation:
let x be angle
90 + 2x = 180, since the sum of the interior angles in a triangle is always 180.
then,
[tex]2x = 90\\x = 45[/tex]
Therefore, the triangle is a 45-45-90 triangle.
You have the measure of IJ, which is one of the legs of the triangle. The way you can find the length of the hypotenuse of a 45-45-90 triangle is by multiplying the length of one of the legs by [tex]\sqrt{2}[/tex].
This means the equation is [tex]IK = IJ\sqrt{2}[/tex]
Answer:
[tex]\sf IK=IJ\sqrt{2}[/tex]
Step-by-step explanation:
The interior angles of a triangle sum to 180°. Therefore, if ΔIJK is an isosceles right triangle where m∠J = 90°:
vertex is m∠J = 90°two base angles are m∠K and m∠ITo calculate the base angles:
⇒ m∠K + m∠I + m∠J = 180°
⇒ m∠K + m∠I + 90° = 180°
⇒ m∠K + m∠I = 90°
⇒ m∠K = m∠I = 45°
Therefore, IJ and JK are the legs of the right triangle and IK is the hypotenuse.
To find the length of the hypotenuse, use Pythagoras' Theorem.
Pythagoras’ Theorem: [tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = IJ = 4b = JK = 4c = IKSubstitute the given values into the formula and solve for IK:
[tex]\sf \implies IJ^2+JK^2=IK^2[/tex]
[tex]\sf \implies 4^2+4^2=IK^2[/tex]
[tex]\sf \implies IK^2=32[/tex]
[tex]\implies \sf IK=\sqrt{32}[/tex]
[tex]\implies \sf IK=\sqrt{16 \cdot 2}[/tex]
[tex]\implies \sf IK=\sqrt{16}\sqrt{2}[/tex]
[tex]\implies \sf IK=4\sqrt{2}[/tex]
As IJ = 4 then:
[tex]\implies \sf IK=IJ\sqrt{2}[/tex]
Two sets of values are given below.
set 1: 29 , 31 , 27 , 33 , 30
set 2: 33 , 31 , 26 , 31 , 29
Which of the following conclusions can be drawn about the means of these two sets?
A. The mean for set 2 is equal to the mean for set 1.
B. The medians of both sets are equal to the means of both sets.
C. The mean for set 2 is lower than the mean for set 1.
D. The mean for set 2 is higher than the mean for set 1.
The correct option is the mean for set 2 is equal to the mean for set 1. (option A).
What is the true option?
Mean is a measure of central tendency that is used to determine the average of a set of numbers.
Mean = sum of the numbers / total number
Mean of set 1 = (29 + 31 + 27 + 33 + 30) / 5
= 150 / 5 = 30
Mean of set 1 = (33 + 31 + 26 + 31 + 29) / 5
= 150 / 5 = 30
Median is the measure of center of a dataset. It determines the value that is at the center of a dataset that is arranged in either ascending or descending order.
Set 1 arranged in ascending order : 27, 29, 30, 31, 33
Median of set 1 = 30
Set 2 arranged in ascending order : 26, 29, 31, 31, 33
Median of set 2 = 31
Differnce in the median = 31 - 30 = 1

OB. y-6=3(x+4)
C. y+6=(x-4)
D. y+6=-3(x-4)
SUBMIT
Answer: y+6 = 1/3(x-4
The equation of line perpendicular to the given line and passes through the point P ( 4 , -6 ) is y + 6 = ( 1/3 ) ( x - 4 )
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y + 1 = -3 ( x - 5 )
So , the slope of the line is m = -3
Now , the lines are perpendicular , so the slope of the line m₂ is
m₂ = 1/3
Let the first point be P ( 4 , -6 )
And , the equation of line is y - y₁ = m ( x - x₁ )
On simplifying , we get
y - ( -6 ) = ( 1/3 ) ( x - 4 )
y + 6 = ( 1/3 ) ( x - 4 )
Hence , the equation of line is y + 6 = ( 1/3 ) ( x - 4 )

Answer:
B is correct.
AB is a common external tangent to circles D and C. The points of tangency are at A and B. DC = 13, BC = 2 and AD = 7.
Find AB.
Based on the calculations, the length of side AB is equal to 13.93 units.
How to find the length of AB?Since the points of tangency are at A and B, we would determine the side length of the point lying between side A and D as follows:
AM = AD - BC
AM = 7 - 2
AM = 5 units.
Now, we can determine the length of side AB by applying Pythagorean's Theorem:
AB² = BM² + AM²
AB² = 13² + 5²
AB² = 169 + 25
AB = √194
AB = 13.93 units.

Step-by-step explanation:
Finding the unit rate of the graph :
Take 2 points and find the slope⇒ (0,0) and (12, 25)⇒ m = 25 - 0 / 12 - 0⇒ m = 25/12The equation is : y = 25/12xNow, the equations with greater unit rates (in increasing order) are :

How many take
(a) All the three subject:
(b) Mathematics, but neither Physics nor Chemistry
(c) Physics, but neither Mathematics nor Chemistry
Answer:
(a) = 13
(b) = 8
(c) = 5
Step-by-step explanation:
Addition theorems on sets are
Theorem 1 :
n(AuB) = n(A) + n(B) - n(AnB)
Theorem 2 :
n(AuBuC) : = n(A) + n(B) + n(C) - n(AnB) - n(BnC) - n(AnC) + n(AnBnC)
Total number of students in the school is not given
so let there are 60 students in the school
using theorem 2
n(AuBuC) : = n(A) + n(B) + n(C) - n(AnB) - n(BnC) - n(AnC) + n(AnBnC)
let n(A) = Mathematics, n(B) =Physics and n(C) = Chemistry
so putting values,
60 = 40 + 42 + 38 - 20 - 28 - 25 + n(AnBnC)
60 +73 -120 = n(AnBnC)
13 = n(AnBnC)
therefore, there are total 13 students who take all three subjects
Number of students who had taken only Mathematics =
n(A) - n(AnB) - n(AnC) + n(AnBnC)
40 - 20 - 25 + 13
53 - 45 = 8 students
Number of students who had taken only Physics =
n(B) - n(BnA) - n(BnC) + n(AnBnC)
42 - 20 - 28 + 13
53 - 48 = 5 students

Skf theatre bought a movie license for rs. 1,500 per week. the cost of keeping the stuff and the hall is rs. 20,000 per month. if they charge rs. 10 per seat, then how many people would have to see the movie in the first four weeks in order for them to recoup the costs?
Answer:
21500
Step-by-step explanation:
21500 people would have to see the movie to recuperate their losses.
The number of people would have to see the movie is given by the equation A = 2600 people
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of people to see the movie in first four weeks be A
Now , the equation will be
The cost of movie license per week = ₹ 1500
The cost of movie license per month = 4 x ₹ 1500
The cost of movie license per month = ₹ 6000
And ,
The cost of keeping the stuff and hall for a month = ₹ 20,000
So ,
The cost of movie license and the hall for a month = 20,000 + 6000
The cost of movie license and the hall for a month = ₹26,000
The cost of charge of each seat = ₹ 10
So , the number of people to see the movie in the first four weeks in order for them to recoup the costs A = cost of movie license and the hall for a month / cost of charge of each seat
Substituting the values in the equation , we get
Number of people to see the movie in first four weeks A = 26000/10
Number of people to see the movie in first four weeks A = 2600 people
Hence , the number of people is 2600 people

If AC is a supplementary line, then
x + 90° + x = 180°
solution:
2x + 90° = 180° |subtract 90° from both sides
2x = 90° |divide both sides by 2
x = 45°
Answer:
[tex] \sf \: b) \: {45}^{o} [/tex]
Step-by-step explanation:
Now we have to,
→ find the required value of x.
Forming the equation,
→ x + x + 90° = 180°
Then the value of x will be,
→ x + x + 90° = 180°
→ 2x = 180° - 90°
→ 2x = 90°
→ x = 90° ÷ 2
→ [ x = 45° ]
Hence, the value of x is 45°.
