find the value of q in the following system x-3y=4

Answer:

The 3 angles are 55°, 55° and 70°

Explanation:

Let the angles of the triangle be a, a and c since two of the angles are the same we can use the same letter to describe the relationships

Sum of all angles of a triangle = 180

a + a + c ==> 2a + c = 180    (1)

We also know c = a + 15

Substituting for c in equation (1) yields

2a + (a + 15) = 180  ==> 3a + 15 = 180 ==> a = (180-15)/3 = 165/3  55°

c = 55 + 15 = 70°

Therefore the 3 angles are 55°, 55° and 70°

The Gulag system was a network of forced labor camps in the Soviet Union, primarily active from the 1930s to the 1950s.

These camps were located in remote regions of Siberia and other parts of the country. The Gulag system was distinct from other forms of punishment due to its scale, brutality, and political nature. It targeted individuals considered enemies of the state, including political dissidents, intellectuals, and perceived threats to the Soviet regime. People were often imprisoned without fair trials, subjected to harsh conditions, forced labor, and widespread human rights abuses. The Gulag system served as a tool of repression and control, suppressing dissent and reinforcing the authority of the Soviet government. It had a devastating impact on the lives of millions of people.

Answer:so what is your question

Explanation:

Answer:

put some rice in a pot

Then mix it up with some sauce

pour in some dirt

and you'll get some sweet plant

Explanation:

Ideally, you need at least 40 continuous days of warm temps over 70 F. (21 C.) to grow rice.

First, you need to find one or several plastic containers without holes. One or several depends upon how many miniature pseudo rice paddies you want to create. Next, either purchase rice seed from a gardening supplier or buy long grain brown rice from a bulk foods store or in a bag. Organically grown rice is best and it can’t be white rice, which has been processed.

Fill the bucket or plastic container with 6 inches (15 cm.) of dirt or potting soil. Add water up to 2 inches (5 cm.) over the soil level. Add a handful of the long grain rice to the bucket. The rice will sink to the dirt. Keep the bucket in a warm, sunny area and move it to a warm place at night.

Rice plants don’t need too much care from here on out. Keep the water level at 2 inches (5 cm.) or so above the dirt. When the rice plants are 5-6 inches (12.5-15 cm.) tall, increase the water depth to 4 inches (10 cm.). Then, allow the water level to lower on its own over a period of time. Ideally, by the time you harvest them, the plants should no longer be in standing water.

If all goes well, rice is ready to harvest in its fourth month. The stalks will go from green to gold to indicate it is time to harvest. Harvesting rice means cutting and gathering the panicles attached to the stalks. To harvest the rice, cut the stalks and allow them to dry, wrapped in a newspaper, for two to three weeks in a warm, dry place.

Once the rice stalks have dried, roast in a very low heat oven (under 200 F./93 C.) for around an hour, then remove the hulls by hand. That’s it; you can now cook with your very own home grown, long grain brown rice.

There were two parts to this test. The first part was where Rosenhan had eight research investors go into a physiocratic hospital and pretend that they were patients. After a while they reported that they were starting to hear voices. After this the five people were sent to a hospital in five different states and then reported that they had felt perfectly fine.  The second stage was when he went to a hospital and told the hospital what was going to happen. The people at the hospital said they could never be fooled. After a short while some of the people had forty-one people that they believed they were Rosenhan collogues. However, he never sent anyone out at all. The conclusion was that the hospital would not be able to tell the difference between a sane person to an insane person. The experiment also showed that once you have an impression on someone it is hard to change that impression.

2. the product will be greater than the fraction and less than the mixed number.

Explanation:

1. Since Nancy needs 4 lengths of fabric that are each 7¾ feet. That means the total length will be:

= 7¾ × 4

= 31/4 × 4

= 31 feet

Since she already has a 36 foot bolt, the number of feet that will be left will be: = 36 - 31 = 5 feet

2. Since the question is about a fraction less than 1 multiplied by a mix number. Let's say the fraction less than 1 is ½ and the mixed number is 2½. Let's multiply them together. This will be:

= ½ × 2½

= ½ × 5/2

= 5/4

= 1 ¼

Base on this calculation, the correct answer is that the product will be greater than the fraction but less than the mixed number.

3. To solve this question, we need to convert 1 ⅔ hours to minutes. Since 60 minutes = 1 hour, 1⅔ hours = 1 ⅔ × 60 minutes = 5/3 × 60 = 100 minutes

Therefore, the number of minutes played before power went out will be:

= 3/4 × 100 minutes

= 75 minutes

Explanation:

Answer:

B. -24

Explanation:

\((5+3i)(-2-4i)\) expands to \(-10 -20i -6i - 12i^2\)

i is the square root of -1, so the \(i^2\) will simplify further and make the equation:\(-10 -20i-6i+12\).

This can be simplified because there are 2 constants, -10 and +12, as well as 2 coefficients to the same variable.

So, the equation becomes:

\(2-26i\)

The question asks of you, what is a+b from the parent expression a+bi.

b is the coefficient that is linked with the variable i.

a has no variable, so it must be the constant.

Here, the value of the "b" coefficient is -26. And the value of the constant is positive 2.

So we have to plug these 2 values into the equation a+b:

\(2+(-26)\)

This solves out as, -24

So, the answer to this question is B.

The value of a + b for i = square root -1 is -24 (Option B)

To determine the value of a + b, we'll begin by obtaining the value of a and b. This can be obtained as illustrated below

(5 + 3i)(-2 - 4i) = a + bi

Expand

5(-2 - 4i) + 3i(-2 - 4i) = a + bi

-10 - 20i - 6i - 12i² = a + bi

-10 - 26i - 12i² = a + bi

But

i = √-1

i² = -1

Thus, we have:

-10 - 26i - 12(-1) = a + bi

-10 - 26i + 12 = a + bi

-10 + 12 - 26i = a + bi

2 - 26i = a + bi

From the above,

Therefore,

a + b = 2 + (-26)

a + b = 2 - 26

a + b = -24

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Answer:

Explanation:

If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.

Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

\(140\% = 1.40\)

John spent $3500.

140% of $3500 is $4900.

So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.

However, the question asks for the price of a single pine.  To find the unit price of a single pine, divide the total revenue by 15.

\(\frac{\$4900}{15pines}=\frac{\$326.\bar{6}}{pine}=\$326.66 \text{ per pine}\)

The average rate of change on interval [1, 6] is equal to 2.

An average rate of change is also referred to as slope and it can be defined as a type of function that describes the average rate at which a quantity changes (decreases or increases) with respect to another quantity, over a period of time (interval).

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by:

Average rate of change = [f(b) - f(a)]/(b - a)

For f(a), we have:

f(a) = f(1) = 1² - 5(1) + 8

f(1) = 1 - 5 + 8

f(1) = 4

For f(b), we have:

f(b) = f(6) = 6² - 5(6) + 8

f(6) = 36 - 30 + 8

f(6) = 14

Substituting the parameters into the formula, we have;

Average rate of change = [f(b) - f(a)]/(b - a)

Average rate of change = [14 - 4]/(6 - 1)

Average rate of change = 10/5

Average rate of change = 2
