At an elevation of 1221.4 feet, Lake Mead will hold 28,945,000 acre-feet of water. Which number is the best estimate of this amo

dsp73

The estimate of the amount 28,945,000 is 3 × 10⁷

<h3>What is an estimate of a value?</h3>

An estimate is a rough or approximate calculation or judgement value.

The question is with regards to the scientific notation which is of the form a × 10ᵇ, where absolute a is of a value 1 ≤ a < 10

The scientific notation form of a number is found as follows;

The decimal point on the number is moved from its position to the point such that the number of non zero numbers to the left of the decimal point is 1

The number b is the number of places to which the decimal point is moved.

b is positive when the decimal point is moved to the left

b is negative when the decimal point in the number is moved to the right

b is zero when the decimal point is not moved

The scientific notation number formed, a × 10ᵇ, which is read as a times 10 raised to the power b.

The zeros in the tail to the right of the decimal point are removed

The number 28,945,000 in scientific notation is 2.8945 × 10⁷

The number part of the scientific notation is approximated to the next higher whole number, as follows;

The first digit to the right of the decimal point is 8 which is larger than 5, therefore the 2 is increased to 3

The approximated number is therefore;

3 × 10⁷

Rachel has 10 sweets in a bag.

LenKa [72]

Using it's concept, it is found that there is a 0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.

<h3>What is a probability?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

One sweet, the probability is 3/10.

For two, the probability is 7/10 then 3/9.

For three, it is 7/10 then 6/9 then 3/8.

So:

$p = \frac{3}{10} + \frac{7}{10} \times \frac{3}{9} + \frac{7}{10} \times \frac{6}{9} \times \frac{3}{8} = 0.713$

0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.

Solve the system of equations.

Brilliant_brown [7]

Answer: B

Step-by-step explanation:

Setting the equations equal to each other,

-5x-8 = 4x+1

-8 = 9x + 1

-9 = 9x

x = -1, meaning y=-5(-1)-8 = -3.

What number must be added to the expression below to complete the square? x^2+x. a.1/4 b.1/2 c.2 d.1

torisob [31]

Option a. 1/4 is the right answer

Step-by-step explanation:

Given expression is:

$x^2+x$

Here

we know that

a = x

In order to find the number which should be added

comparing with the formula

$(a+b)^2 = a^2+2ab+b^2$

$2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}$

So, we will add the square of 1/2 which is 1/4

Hence,

Option a. 1/4 is the right answer
