Answer:

<h2>Original price = $ 120</h2>

Step-by-step explanation:

To find the original price given the new price and percentage discount we use the formula

$original \: \: price = \frac{100}{(100 - x)} \times new \: \: price \\$

where

x is the percentage discount

From the question

new price = $ 84

% discount = 30%

Substitute the values into the above formula and solve

That's

$original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10$

We have the final answer as

<h3>Original price = $ 120</h3>

Hope this helps you

If the same BLANK number is multiplied to each side of a true inequality, the inequality sign is reversed to make the resulting

Maurinko [17]

Answer: Negative
If the same negative number is multiplied to each side of a true inequality, then the inequality sign flips to make the new inequality true as well

Example:
Take 1 < 5 and multiply both sides by -2 and we get -2 > -10. The "less than" sign flips to "greater than" since -2 < -10 is false. The value of -10 is further to the left of -2 so -10 is smaller in value. The negative basically takes the complete opposite which is why the flip must happen.

This sign flip rule does not happen if you multiply both sides by a positive number.

The amount of lateral expansion (mils) was determined for a sample of n = 8 pulsed-power gas metal arc welds used in LNG ship co

Alona [7]

Answer:

95% Confidence interval for the variance:

$3.6511\leq \sigma^2\leq 34.5972$

95% Confidence interval for the standard deviation:

$1.9108\leq \sigma \leq 5.8819$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the standard deviation σ and the variance σ².

The sample, of size n=8, has a standard deviation of s=2.89 miles.

Then, the variance of the sample is

$s^2=2.89^2=8.3521$

The confidence interval for the variance is:

$\dfrac{ (n - 1) s^2}{ \chi_{\alpha/2}^2} \leq \sigma^2 \leq \dfrac{ (n - 1) s^2}{\chi_{1-\alpha/2}^2}$

The critical values for the Chi-square distribution for a 95% confidence (α=0.05) interval are:

$\chi_{0.025}=1.6899\\\\\chi_{0.975}=16.0128$

Then, the confidence interval can be calculated as:

$\dfrac{ (8 - 1) 8.3521}{ 16.0128} \leq \sigma^2 \leq \dfrac{ (8 - 1) 8.3521}{1.6899}\\\\\\3.6511\leq \sigma^2\leq 34.5972$

If we calculate the square root for each bound we will have the confidence interval for the standard deviation:

$\sqrt{3.6511}\leq \sigma\leq \sqrt{34.5972}\\\\\\1.9108\leq \sigma \leq 5.8819$

If i am making $4 billion / sec then how much money would i have in 10 minutes? if i am making $6 billion / sec then how much mo

Ghella [55]

If you are making 4 billion a second do 4,000,000,000 x 60 = 240,000,000,000
Then times that by 10 which equals. 2,400,000,000,000

Is the answer for the second one
6,000,000,000 x 60 x 60 x 2 = 1,296,000,000,000,000

Triangle ABC is similar to Triangle FGH. What is the value of x in centimeters?

EleoNora [17]

<u>Given</u>:

Given that the triangle ABC is similar to triangle FGH.

We need to determine the value of x.

<u>Value of x:</u>

Since, the triangles are similar, then their sides are proportional.

Thus, we have;

$\frac{AC}{FH}=\frac{AB}{GF}=\frac{BC}{GH}$

Let us consider the proportion $\frac{AB}{GF}=\frac{BC}{GH}$ to determine the value of x.

Substituting AB = 9 cm, GF = 13.5 cm, BC = 15 cm and GH = x, we get;

$\frac{9}{13.5}=\frac{15}{x}$

Cross multiplying, we get;

$9x=15 \times 13.5$

$9x=202.5$

$x=22.5 \ cm$

Thus, the value of x is 22.5 cm

Hence, Option F is the correct answer.

Integrate 2x/sqrt(1-x^2) dx from 0 to ½.

8_murik_8 [283]

A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
