the difference of a positive integer and its inverse is 15/4. find the integer

Answers

Answer 1
If the integer is x, and the inverse is 1/x, we have x-1/x=15/4 (since difference is subtraction). Multiplying both sides by x, we get x²-1=15x/4. Next, we can subtract 15x/4=3.75x from both sides to get x²-3.75x-1=0. Using the quadratic formula, we get [tex]x= \frac{3.75+- \sqrt{(-3.75)^2-(4*-1*1)} }{2} = \frac{3.75+- \sqrt{14.0625+4} }{2} = 4, -0.25. [/tex]

Since it has to be a positive integer, we get x=4

The ratio of girls to boys in the junior high band is 5 to 7. At the beginning of the year, there were 72 students in the band. By the end of the year, the ratio of girls to boys was 3 to 4. If there are now 48 boys in the band, how many girls joined the band during the school year?

Answers

Ratio is 5girls:7boys with total 72 students 
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys

New ratio is 3:4 with 48 boys

48➗4= 12

So for girls 3x12= 36

So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.
36 is the amount of girls and 48 boys

the exact temperature of a glass of water in degrees Celsius

Answers

Final answer:

To find the exact temperature of a glass of water in degrees Celsius, a thermometer operating on the Celsius scale is used. The Celsius scale marks water's freezing point as 0 °C and it's boiling point as 100 °C with 100 equal intervals in-between these points. Note that the specific heat of water, the amount of heat needed to increase the temperature, is greater than many substances including glass.

Explanation:

In order to determine the exact temperature of a glass of water in degrees Celsius, you will use a thermometer that operates on the Celsius scale. The freezing and boiling points of water are key reference points on this scale. When using the Celsius scale, the freezing point of water is defined as 0 °C and the boiling point as 100 °C. The space between these two temperatures is divided into 100 equal intervals, which we define as degrees. Likewise, the Fahrenheit scale has the freezing point of water at 32 °F and the boiling point at 212 °F, a 180-interval scope which is also divided into degrees. Consequently, one degree difference on the Celsius scale is equivalent to 1.8 degrees Fahrenheit difference. Furthermore, the SI unit of temperature is the kelvin (K), but also widely used is the degree Celsius (°C).

The specific heat of a substance, in this case water, also plays a role. The specific heat of water is noticeably higher than that of glass, meaning that more heat is required to raise the temperature of water than glass by an equal number of degrees. Exact values of specific heat for different substances, including water, often have to be looked up in tables because there is no straightforward way to calculate them.

Final answer:

The algebraic expression for how many candies each girl gets if Sam, Liz, and Ann, who initially had s, l, and a candies respectively, share all their candies evenly is (s + l + a) / 3.

Explanation:

This question is referring to a problem in basic algebra. Here we have three individuals: Sam, Liz, and Ann. They each start with a certain number of candies, represented by the variables s, l, and a respectively. The question is asking how many candies each girl has if they all share their candies evenly.

To find this, you would first add up all the candies, which can be represented algebraically as (s + l + a). Since they share equally, you would divide the total number of candies by the number of girls which is three in this scenario. The algebraic expression to represent this would be (s + l + a) / 3. So, each girl gets (s + l + a) / 3 candies.

−dx+3x=m−9

Step 3: Factor out variable x.x(−d+3)=m−9

Step 4: Divide both sides by -d+3.

the answer is x=m-9/-d+3

plz mark brainliest 

Answer:

[tex]x=\frac{m-9}{3-d}[/tex]

Step-by-step explanation:

We have been given an equation [tex]m=9+3x-dx[/tex]. We are asked to solve the given equation for x.

Subtract 9 from both sides:

[tex]m-9=9-9+3x-dx[/tex]

[tex]m-9=3x-dx[/tex]

Factor out x from right side:

[tex]m-9=x(3-d)[/tex]

Switch sides:

[tex]x(3-d)=m-9[/tex]

Divide both sides by [tex](3-d)[/tex]:

[tex]\frac{x(3-d)}{3-d}=\frac{m-9}{3-d}[/tex]

[tex]x=\frac{m-9}{3-d}[/tex]

Therefore, the value of x is [tex]\frac{m-9}{3-d}[/tex].

Kayla has a standard deck of 52 cards and a six-sided die. What is the probability that she will pull a diamond from the deck of cards and roll a 1?

Answers

Probability( Pulling a diamond) = 1/4
Propability(Rolling a 1)  = 1/6 

The 2 events are independent so the probabilities are mulitplied:-

Required probability  = 1/4 * 1/6 = 1/24 Answer


Answer: 4.2%

Step-by-step explanation:

The deck has 52 cards, and a standard deck has 13 cards of each type, so there are 13 diamond cards.

Then the probability of drawing a random card that is a diamond card is equal to the number of diamonds card divided by the total number of cards:

p1 = 13/52 = 0.25

now, for the dice we have that the dice has 6 sides, but only one side has a 1, so the probability is;

p2 = 1/6 = 0.167

Now, the probability of both events happening at the same time, is equal to the product of both probabilities is:

P = p1*p2 = 0.25*0.167 = 0.042

So the probability is 0.042*100% = 4.2%

where, m is slope and b is y-intercept.

From the given graph it is clear that the graph intersect the y-axis at (0,2). So, the y-intercept of the line is 2.

The line passes through the points (0,2) and (4,3). So, the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{3-2}{4-0}[/tex]

[tex]m=\frac{1}{4}[/tex]

Substitute [tex]m=\frac{1}{4}[/tex] and b=2 in equation 1.

The equation of line is [tex]y=\frac{1}{4}x+2[/tex].
