X=4/5 Y=4/X+SQRT X +0.2 -5X What is the value of Y

1 answer:

5 0

You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:

y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

A stop sign is shown. Each side measures 12.4 inches and the distance from any side to the opposite is 30 inches. Divide the sto

Daniel [21]

A stop sign has a total of 8 sides measuring 12.4 inches on each side and 30 inches for the distance of each sides.

Given the measurement, the rectangle's dimensions are as follows:

If divided horizontally: Length = 12.4 inches, width = 30 inches

If divided vertically: Length = 30 inches, width = 12.4 inches

From the divided rectangle, we can produce a 3-side equal trapezoid. In this case, we will have a uniform measurement of 12.4 inches on each side and 30 inches for the longer side.

Write three numerical expressions that are equivalent to (0.0004) . (0.005)

yKpoI14uk [10]

The three equivalent numerical expressions are:

$(0.0004) . (0.005) = (\frac{4}{10000}).(\frac{5}{1000})$

$(0.0004) . (0.005)= (\frac{1}{2500}).(\frac{1}{200})$

$(0.0004) . (0.005) = (4 \times 10^{-4}).(5 \times 10^{-3})$

Solution:

We have to write three numerical expressions that are equivalent to (0.0004) . (0.005)

Given expression is:

(0.0004) . (0.005)

First numerical expression:

We know that 0.0004 can be written in fraction as:

$0.0004 = \frac{0.0004 \times 10000}{10000} = \frac{4}{10000}$

Similarly,

$0.005 = \frac{0.005 \times 1000}{1000} = \frac{5}{1000}$

Therefore,

$(0.0004) . (0.005) = (\frac{4}{10000}).(\frac{5}{1000})$

Second numerical expression:

The first numerical expression can be simplified to get second numerical expression

$(\frac{4}{10000}).(\frac{5}{1000}) = (\frac{1}{2500}).(\frac{1}{200})$

Third numerical expression:

The given expression can be expressed in scientific notation:

Steps for converting to scientific notation:

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

$0.0004 = 4 \times 10^{-4}\\\\0.005 = 5 \times 10^{-3}$

Therefore, third equivalent numerical expression is:

$(0.0004) . (0.005) = (4 \times 10^{-4}).(5 \times 10^{-3})$

The median number of baskets made by 7 players in a certain basketball game is 5. The range of the number of baskets made by tho

shepuryov [24]

This must be FALSE, because:

7 players x 4(which is the range) = 28 which means that the total number of baskets made is 28.

If the greatest is 8, we must do 28 - 8, which gives us 20. This means that the remaining 6 players (7 - 1 = 6) made a total of 20 baskets.

However, if the fewest is 4 baskets, this means that the remaining 5 players (6 - 1 = 5) must have made a total of 16 baskets (20 - 4 = 16) and that each player must have scored 4 or more baskets each (since 4 was the fewest number of baskets made).

But this is impossible because if the remaining 5 players scored 4 (fewest number possible) each, it would give us 20 (4 x 5). But they should have made 16, or else the total of all the baskets would not be 28 (look back at start).

This means that the statement is impossible and therefore FALSE.

Hope this helped :)

The function below represents the interest Kristina earns on an investment. Identify the term that represents the amount of mone

Elena-2011 [213]

Answer:

The amount of money originally invested which is the principal P = 5,000

Step-by-step explanation:

Using the compound interest formula, the return on investment can be represented on the interest function as;

f(x) = P(1+r)^x

Where

P is the principal which is the initial investment.

r = rate Proportion

x = time (number of years)

Comparing to the given function;

f(x) = 5,000(1 + 0.04)^x

We can see that;

Principal P = 5,000

Rate r = 0.04

time = x

The amount of money originally invested which is the principal P = 5,000

The sum of two numbers is 90. The larger number is 14 more than 3 times the smaller number. Find the numbers

e-lub [12.9K]

Answer:

The numbers are 19 and 71.

Step-by-step explanation:

Let x and y represent the two numbers. Then x + y = 90.

Also, if we assume that the larger number is y, then y = 3x + 14.

We must solve this system of linear equations. Since we already have the result of solution for y (y = 3x + 14), let's use the substitution method to find the solution:

x + y = 90 becomes x + 3x + 14 = 90, or:

4x = 76. Thus, x = 76/4, or 19. If x = 19, then y = 3(19) + 14, or y = 71.

The numbers are 19 and 71.

Note that these add up to 90, as they must, and that 71 is 14 more than 3 times 19.
