Find the number of non-prime factors of 4^10 x 7^3 x 5^9.​

Answer»

Answer:

2^5*3^7*3^4*11^4*13^3

2^5*3^11*11^4*13^3

Number of FACTORS: (5+1)(11+1)(4+1)(3+1)=6*12*5*4=1440

The only PRIME factors are 2, 3, 11, and 13. All other factors are not prime.

Therefore, there are 1440–4 = 1436 NON prime factors.

If 10A x 3 = 31A, then A is given bya) 0b) 3c)5c)1​

Answer»

Answer:

a)0

Step-by-step explanation:

because if you observe carefully you can see that the product of two different NUMBERS from a same number is EQUAL which is only possible when the second number is 0.

10A×3=31A

30A=31A=>30=31 which we know is fundamentally wrong.

this happens because A can only be ZERO and to cancel it from both sides MEAN dividing both sides by zero which is an INDETERMINATE.

Q.29 During a sale, a shop offered a discount of 10% on the marked prices of all the items. What would acustomer have to pay for a pair of jeans marked atRs 1450 and two shirt marked at Rs 850 each?​

Answer»

Answer:

For a pair of jeans

Marked price =Rs.1450

Discount =10% of Rs.1450

=

100

10

×1450

=Rs.145

∴ Sale price =1450−145

=Rs.1305

For two shirts

Marked price =(Rs.850)×2=Rs.1700

Discount =10% of Rs.1700

=

100

10

×1700

=Rs.170

∴ Sale price =1700−170

=Rs.1530

Total sale price =1305+1530

=Rs.2835

Thus, the CUSTOMER would have to PAY Rs.2835

find the area of triangle ABC whose coordinates are A(4,-6)B(3,-2)C(5,2) then find the length of the median AD​

Answer»

GIVEN :-

  • Coordinates of A = ( 4 , -6 )
  • Coordinates of B = ( 3 , -2 )
  • Coordinates of C = ( 5 , 2 )

To FIND :-

  • Area of the triangle ABC

Solution :-

\red\bigstar\: \boxed{\bf \green{Area = \frac{1}{2} \bigg[x_1(y_2 - y_3) + x_2(y_3 - y_1) +x_3(y_1 - y_2) \bigg ]}} \\

Here

  • x₁ = 4
  • x₂ = 3
  • x₃ = 5
  • y₁ = -6
  • y₂ = -2
  • y₃ = 2

Substitute values in formula

\longmapsto \sf Area = \frac{1}{2} \bigg[4(-2-2) + 3(2 + 6) +5( - 6 + 2) \bigg ] \\

\longmapsto \sf Area = \frac{1}{2} \bigg[4(-4) + 3(8) +5( - 4) \bigg ] \\

\longmapsto \sf Area = \frac{1}{2} \bigg[ - 16+24 - 20\bigg ] \\

\longmapsto \sf Area = \frac{1}{2} \bigg[ - 12\bigg ] \\

\longmapsto\boxed{\sf\purple{ Area =  - 6 \:  {unit}^{2}} }\\
