How many pounds is in 0.75 tons

Well, darling, the value of the 7 in 72 is 7. It's not rocket science, honey. It's just basic math. Next question, please!

In financial notation, "2.5k" represents 2,500 dollars. The "k" in this context stands for "thousand," so when you see "2.5k," it means 2.5 thousand dollars. This shorthand is commonly used in informal or abbreviated financial discussions or notations.

7 x 25 = 175

Well, isn't that a happy little number! When we round 6.12 to one decimal place, we see that it becomes 6.1. Just like painting a beautiful landscape, sometimes simplifying things can bring a sense of peace and clarity.

To write the number 18,000,000 in words, you would say "eighteen million." This number is composed of two parts: "eighteen," which represents the number of millions, and "million," which indicates the magnitude of the number. It is important to note the placement of commas in large numbers to separate the digits into manageable groups.

The value of the underlined digit 5 in 755, 204 is times the value of the digit 5 that is not underlined.

A vector is a mathematical entity that has both magnitude and direction, often represented graphically as an arrow. Common examples of vectors include velocity, which describes the speed and direction of an object, and force, which indicates the push or pull applied to an object in a specific direction. Other examples include displacement and acceleration, both of which convey how far and in what direction something moves.

The SBR number on an SSS (Social Security System) form in the Philippines stands for "Statement of Benefits Received." It is a unique identifier assigned to track the benefits availed by a member. This number is essential for processing claims, ensuring accurate record-keeping, and facilitating communication regarding a member's benefits and contributions.

The answer for 7 multiplied by 8 is 56.

if the balls are in the ratio of 7:10, then in every 7+10 = 17 of them 7 are white and 10 are black.

With 136 marbles there are 136 ÷ 17 = 8 lots

→ there are 8 lots × 7 white/lot = 56 white.

Rule

#1 . Use The SAME coefficient in all cases

#2 ; When multiplying ; add the radicals

#3 ; When dividing subtract the radicals

#4 ; When 'nesting' multiply the radicals.

Here is an example /

3^(4) X 3^(7)

Rule 1 ; '3' is the coefficient

Rule 2 ; multiplying 3^(4 + 7) = 3^(11)

4^(5) divide 4 ^(7)

Rule 1 ; same doefficient '4;

Rule 3 ; 4^(5-7) = 4^(-2) or 1/4^(2)

[5^(3)]^(2)

Rule 1 ; same coefficient '5'

Rule 4 ; Nesting ; 5^(3X2)= 5^(6)

NB You CANNOT do 2^*3) X 3^(2) by saying 6^(6) WRONG Answer!!!!!

x^(2) = 201.64

find square root of both sides.

Hence

x = sqrt( 201.64(

x = 14.2

y = kx + 1

y^(2) = 8x

Square up the linear eq'n and substitute.

Hence

y^(2) = ( kx + 1)^(2)

(kx + 1)^(2) = 8x

Square out the brackets

(kx)^(2) + 2kx + 1 = 8x

(kx)^(2) + (2k-8)x + 1 = 0

Apply the discriminant

b^(2) -4ac = 0

(2k - 8)^(2) - 4(k)^(2)(1)

4k^(2) - 32k + 64 - 4k^(2) = 0

32k - 64 = 0

32k = 64

k = 2

=64

The product of 1000000000000000000000000000000 and 100000000000000000000000000000000000000000000000000000000000000 is 1 x 10^48, or 1 followed by 48 zeros. This can be obtained by adding the exponents of 10 from each number: 30 + 50 = 80. Therefore, the result is 1 with 48 zeros after it.

25% of 2,000,000 = 0.5 million - 500,000 ( five hundred thousand).

a^(3) + a^(2)

Factors to

a^(2) [ a^(2) + 1 ]

NB THe terms in the square brackets do NOT factor. Reason, Any ywo squared terms with a positive (+) between then does NOT factor

Think of a^(2) + 1 as a^(2) + 1^(2) .

A pair of squared terms with a negative between them DOES factor.

So if you initial expression was a^(4) - a^(2)

Then

a^(2) [ a^(2) - 1^(2)]

a^(2)[a - 1)(a + 1) Fully factored.

Note the two different signs.
