Answer:

x=4

Step-by-step explanation:

4(5x+2)=14x+32

20x+8 = 14x+32

20x-14x+8=14x-14x +32 (Both side +14x)

6x+8=32 (cancel 14x -14x)

6x+8-8=32 -8(both side -8)

6x=24 (both side divide 6)

6x/6=24/6

x=4

Answer:

34x+34

Step-by-step

20x+2=14x+32

20x+14x=2+32

34x+2+32

2+32=34

34x=34

Answer:

37 m

Step-by-step explanation:

First, use trigonometric ratio to find the distance between the top of the shorter silo to the top of the taller silo.

Let the distance between the top of the smaller silo and the top of the taller silo be x.

Thus, we would have:

Tan 30 = opp/adj = x/25

Tan 30 = x/25

Multiply both sides by 25

25*Tan 30 = x

x = 14 m (nearest meter)

The height of the taller silo = height of the smaller silo + x

= 23 m + 14 m

= 37 m

Calculator Use

Calculate the sale price you will pay for an item based on the type of discount in the sale promotion:

Percent off list price

Fraction off list price

Multi-item discount

You can also compare discounts to find the lowest price for an item. Enter a percentage off price, fraction off price, multiple items for the price of one or other "two-for" type discounts. Compare the final discounted price for each in the answer table.

Sale Price Formulas and Calculations

Percent Off Price Formula

Discounted price = List price - (List price x (percentage / 100))

Example: Sale price is 25% off list price of $130

Convert 25% to a decimal by dividing by 100: 25/100 = 0.25

Multiply list price by decimal percent: 130*0.25 = 32.50

Subtract discount amount from list price: 130 - 32.50 = 97.50

With the formula:

130 - (130*(25/100)) =

130 - (130*0.25) =

130 - 32.50 = 97.50

25% off $130 is $97.50

Answer:

103.96

Step-by-step explanation:

100% (full price)                                                             --> 129.95

80% (retail price = 100%(full price) - 20% (discount)) --> x

x = 80*129.95/100 = 103.96

Answer:

Since slopes of both lines are not negative reciprocals. Therefore Lines are not perpendicular to each other

Step-by-step explanation:

Slope of -7x-2y=-8 is -7/2

Slope of 2x+7y=-3 is -2/7

For perpendicular lines slopes are negative reciprocals of each other

Answer:

  15.8 ÷ 3.9

Step-by-step explanation:

To make up this problem, we can start with two numbers whose quotient we know is 4, such as 16 and 4. Then we can choose two numbers that round to these values, such as 15.8 and 3.9

__

The problem 15.8 ÷ 3.9 has an estimated quotient of 4. The estimate is found by rounding each value to the nearest integer and finding the quotient of those numbers: 16/4 = 4.

_____

Additional comment

The actual quotient is 4 2/39, about 4.05128.

You haven't listed the information in the table, but that's okay :). I believe I can still help you.

To find the average score on the test for this group you would have to add up all the test scores listed in the chart, then divide that sum by the number of people in the group.

Here's an example;

I'll make a list of people with some test scores

Jimmy- 80

Andrea- 44

Samuel- 15

Jerica- 65

To find the average of their scores, I'll first add up their points:

80+44+15+65 = 204

Once I've calculated my sum, I will divided that sum by the number of people who took the test. In this case it's 4 different people, so :

204÷4= 51

So in my made up scenario the average score in my group was 51.

Now you can apply this process into your problem.

(Hope this helps :). Please let me know if you need more help on this problem)

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Answer:

The answers are that x = 8 and y = 7%

Step-by-step explanation:

To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).

1.36/17% = 8

And now to find y, we divide 1.05 by 15

1.05/15 = 7%

Answer:

i think its 32 pints

Step-by-step explanation:

im pretty sure but sorry if im wrong ❤️

The remaining honey in the beehive is 4 gallons and 2 quarts, or 4 quarts and 2 ounces.

we need to convert the given measurements to quarts and ounces and then subtract them from the original 5 gallons.

1 gallon is equal to 4 quarts, and 1 quart is equal to 32 ounces.

4 gallons can be converted to quarts by multiplying by 4:

4 gallons × 4 quarts/gallon = 16 quarts

1 pint is equal to 2 cups, and 1 cup is equal to 8 fluid ounces.

1 pint and 2 ounces can be converted to ounces:

1 pint × 2 cups/pint × 8 ounces/cup = 16 ounces

2 ounces (already in ounces) = 2 ounces

Now, let's add up the converted measurements:

16 quarts + 16 ounces + 2 ounces = 16 quarts and 18 ounces

To find the remaining honey, we subtract the converted measurements from the original 5 gallons:

5 gallons - 16 quarts - 18 ounces = 4 gallons and 2 quarts

Answer:

2.5v + 5 < 5v is the correct answer.

Step-by-step explanation:

Given that:

Cost to rent one game at store S = $2.50

Monthly fee = $5.00

Let,

v be the number of video games.

Total cost = 2.50v + 5

Cost to rent one game at store T = $5.00

y = 5v

Now,

Store S < Store T

2.50v + 5 < 5v

Hence,

2.5v + 5 < 5v is the correct answer.

Answer:

The diameter of each coin is approximately 2.778 centimeters.

Step-by-step explanation:

According to the statement, 0.12 cubic meters ([tex]1.20\times 10^{8}\,mm^{3}[/tex]) were used to produce 99000 coins. First, we calculate the volume of each coin ([tex]V_{c}[/tex]), measured in cubic meters, by dividing the total volume by the number of coins. That is:

[tex]V_{c} = \frac{1.20\times 10^{8}\,mm^{3}}{99000}[/tex]

[tex]V_{c} =1212.121\,mm^{3}[/tex]

Then, diameter ([tex]D[/tex]), measured in milimeters, can be derived from the following volume formula:

[tex]V_{c} = \frac{\pi}{4}\cdot D^{2}\cdot h[/tex] (1)

Where [tex]h[/tex] is the thickness of the coin, measured in milimeters.

If we know that [tex]h = 2\,mm[/tex] and [tex]V_{c} =1212.121\,mm^{3}[/tex], then the diameter of each coin is:

[tex]D^{2} = \frac{4\cdot V_{c}}{\pi\cdot h}[/tex]

[tex]D = 2\cdot \sqrt{\frac{V_{c}}{\pi\cdot h} }[/tex]

[tex]D = 2\cdot\sqrt{\frac{1212.121\,mm^{3}}{\pi\cdot (2\,mm)} }[/tex]

[tex]D \approx 27.779\,mm[/tex]

The diameter of each coin is approximately 2.778 centimeters.

Answer:

The 90% confidence interval for pis (0.7342, 0.8658).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

100 rats mothers, 80 went right. So [tex]n = 100, \pi = \frac{80}{100} = 0.8[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 - 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.7342[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 + 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.8658[/tex]

The 90% confidence interval for pis (0.7342, 0.8658).

Answer:

TRUE

Step-by-step explanation:

Standard deviation is defined as the measure of spread. In other words, it shows and determines how spread out the numbers are, i.e. the amount of dispersion or variation of a given set of numbers.

The standard deviation ranges from zero to any number. So it is possible to have a standard deviation of number 445,000 because the standard deviation can be of any value greater than or equal to zero.

Using the standard deviation concept, it is found that since the standard deviation is always a positive value or zero, the statement is true.

Hence, considering that  the standard deviation is always a positive value or zero, the statement is true.
