Answer:
14 and 21
Step-by-step explanation:
This is not an easy question, but luckily we can have an idea to solve this.
In this case, we need to apply the relation between HCF and LCM, which is the following:
HCM * LCM = Number 1 * Number 2
In other words, the multiplication of both factors is equal to the multiplication of the given numbers that we are looking for. Now, we do not know the numbers but we can have an idea of which numbers can be when we calculate the product of the factors:
HCM * LCM = 42 * 7 = 294
We know that the products should result 294, and if the HCM is 7, means that both numbers can be divided by 7 as the highest factor, so, let's write the multiple of 7:
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
With these we can have an idea, if 42 * 7 = 294, all we just need is to find others two numbers that the result gives 294:
14 * 7 = 98
14 * 21 = 294
14 and 21 could be the numbers, but let's confirm writting their multiples
HCM of 14: 1, 2, 7, 14
HCM of 21: 1, 3, 7, 21
LCM of 14: 14, 28, 42, 56, 70
LCM of 21: 21, 42, 63, 84
As you can see, The HCM and LCM of 14 and 21 are 7 and 42, therefore the pair of numbers are:

4. The apples bought by Neetu was of weight 3 ¾ kg and the apples bought by Naren was of weight 2 ½ kg. Who bought more apples and by how much more did it weigh?
Answer:
5/4kg
Step-by-step explanation:
Given data
Weight of apples bought by Neetu= 3 ¾ kg
Weight of apples bought by Naren= 2 ½ kg
From the numbers/weights above, Neetu bought more apples
=3 ¾ kg to simple fraction
= 15/4 kg
=2 ½ kg kg to simple fraction
= 5/2 kg
The difference is
=15/4-5/2
=15-10/4
= 5/4kg
Hence Neetus Apples is 5/4kg morethan Narens Apples

find the unknown angles. QRT and SRV are congruent
Answer:
52
Step-by-step explanation:
so all of the angles added together will equal 180 and if angle qrt and angle srt are congruent then they are equal to each so first we subtract 76 from 180 and get 104. then we divide it by 2 because the two missing angles are congruent. 104/2=52 so h and j =52

An hour before show time, only 105 people have arrived to the concert. According to the statistics, 95% of the people have yet to arrive. How many tickets were sold for the concert?
Answer: 2,100 tickets
Step-by-step explanation:
105 people have arrived for the concert yet it is said that 95% of people are yet to arrive. This means that the 105 people are 5% of the tickets sold.
Assume the total number of tickets sold is x:
5% * x = 105
0.05x = 105
x = 105 / 0.05
x = 2,100 tickets
Answer:
2100
Step-by-step explanation:
x= 2,100
5% x = 105
0.05x = 105
x = 105/0.05

A TV and Washing machine were purchased for Rs 15000 each. If together, they are sold at Rs 35000, What is Profit and Profit%
Given:
A TV and Washing machine were purchased for Rs 15000 each.
Together, they are sold at Rs 35000.
To find:
The profit and profit%.
Solution:
A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is
[tex]C.P.=15000+15000[/tex]
[tex]C.P.=30000[/tex]
Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.
Now,
[tex]Profit=S.P.-C.P.[/tex]
[tex]Profit=35000-30000[/tex]
[tex]Profit=5000[/tex]
And,
[tex]Profit\%=\dfrac{Profit}{C.P.}\times 100[/tex]
[tex]Profit\%=\dfrac{5000}{30000}\times 100[/tex]
[tex]Profit\%=\dfrac{50}{3}[/tex]
[tex]Profit\%\approx 16.67[/tex]
Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.

The length of a rectangle is 5m longer than its width. If the perimeter of the rectangle is 54m, find its length and width.
Answer:
Width=11
Length=16
Step-by-step explanation:
P=2L+2W
54=2(5+w)+2w
Open the brackets
10+2w+2w=54
10+4w=54
Collect the like terms
4w=54-10
4w/4w=44/4
W=11
Since the length is 5m longer
Therefore:11+5=16
Width=11
Length=16

The base of a regular pyramid is a hexagon.
What is the area of the base of the pyramid?
Enter your answer in the box. Express your answer in radical form.
Answer:
Step-by-step explanation:
For the single triangle
sin60=h/14, h=14sin60
cos60=b/(2(14)), b/2=14cos60 so the total area is nhb/2 where n is the number of sides
A=n(14sin60)(14cos60), since n=6
A=6(14sin60)(14cos60)
A=114.75cm^2
The hexagon is divided into 6 equal triangles. Then the area of the base of the pyramid is 509 square cm.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The base of a regular pyramid is a hexagon.
The hexagon is divided into 6 equal triangles. Then the height of the triangle will be
[tex]\rm a = 14 \sin 60^o\\\\a = 12.12[/tex]
Then the area of the triangle will be
[tex]\rm Area \ of \ triangle = 0.5 \times 14 \times 12.12\\\\Area \ of \ triangle = 84.84 \ cm^2[/tex]
Then the area of the base of the pyramid will be
[tex]\rm Area \ of \ base \ pyramid = 6 \times Area \ of \ triangle\\\\Area \ of \ base \ pyramid = 6 \times 84.84\\\\Area \ of \ base \ pyramid = 509.04 \approx 509 \ \ cm^2[/tex]
