If I understand what you're saying. It would be the absolute value of -37, which is 37. Also, the absolute value of 37 is 37.

The absolue valor of 37 is 37

It is known that 60 minutes equals 1 hour.

Therefore, the first thing we do to solve the problem is to calculate how many hours are equivalent to 96 minutes.

For that we calculate:

[tex]96 minutes * \frac{1 hour}{60minutes}=\frac{96}{60}=1.6hours\\[/tex]

Thus:

96 minutes = 1.6 hours.

1.9 ounces of water are lost every 1.6 hours.

Therefore, in 8 hours the amount of water lost  is:

[tex]\frac{8hours}{1.6hours}*1.9 = 9.5\\[/tex] ounces of water

After 8 hours, 9.5 ounces of water are lost

Therefore, the amount of water left in the tank after 8 hours is:

[tex]80 000-9.5=79990.5[/tex] ounces

we know that

the equation of the line in point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

use the point B (7,7)

[tex]y-7=(-7/6)*(x-7)[/tex]

therefore

the answer part c) is

[tex]y-7=(-7/6)*(x-7)[/tex]

Part d)

we know that

the equation of the line in slope-intercept for is equal to

[tex]y=mx+b[/tex]

we have

[tex]y-7=(-7/6)*(x-7)[/tex]

[tex]y=(-7/6)x+(49/6)+7[/tex]

[tex]y=(-7/6)x+(91/6)[/tex]

therefore

the answer Part d) is

[tex]y=(-7/6)x+(91/6)[/tex] or [tex]y=-1.167x+15.167[/tex]

Answer:

Since discriminant is positive, therefore, the given quadratic equation has two real solutions. Correct answer is the last option.

Step-by-step explanation:

We have been given a quadratic equation and we need to figure out the number of real solutions of the equation.

[tex]2x^{2}+7x-15=0[/tex]

We know that discriminant of a general quadratic equation [tex]ax^{2}+bx+c=0[/tex] is given by [tex]D=b^{2}-4ac[/tex]

For the given quadratic equation [tex]2x^{2}+7x-15=0[/tex], we have [tex]a=2,b=7,c=-15[/tex]. Upon substituting these values in the formula for discriminant, we get:

[tex]D=7^{2}-4(2)(-15)[/tex]

[tex]D=49+120[/tex]

[tex]D=169[/tex]

Since discriminant is a positive number, therefore, the given quadratic equation has two real solutions. Hence, the last option is the correct answer.

Area is a squared number.  We know that from the label we use when we solve problems involving area.  Perimeter is a single unit label.  This single unit label can also be used to find scale factor, since single unit labels are one-to-one.  If the area of polygon F is 36, that means that the single unit measure was a number that was squared to get to the area.  Same goes for polygon G.  That means that in order to find the single unit measure of each of those we have to take the square root of the area.  The square root of 36 is 6, and the square root of 4 is 2.  6:2 is the scale factor, but that can be reduced to 3:1, larger to smaller.

There were 375 adult tickets sold.

This question involves a concept in basic algebra. Let's denote the number of adult tickets as A and the number student tickets as S. From the problem, we know that the total number of tickets sold is 676, so A+S=676. The problem also tells us that there were 74 fewer student tickets sold than adult tickets, so we know that S=A-74.

We can substitute the value of S from the second equation into the first equation which gives us A+(A-74)=676. By solving this equation we find that A=375, so there were 375 adult tickets sold.

Let's denote the number of adult tickets sold as x. Since there were 74 fewer student tickets sold, the number of student tickets sold is x - 74. The total number of tickets sold is the sum of the adult and student tickets, which is 676.

Therefore, we can write the equation:

x + (x - 74) = 676

Simplifying the equation:

2x - 74 = 676

Adding 74 to both sides:

2x = 750

Dividing by 2:

x = 375

So, 375 adult tickets were sold.

There is 1 serving of lemon juice to 3 cups water. Hence why it's 1:3 ratio.

Since it's 1:3, then 2 servings to 6 cups of water, so on and so forth.

Multiply your lemon juice servings by 3 to find out how many cups of water for the table.

To find how much lemon juice for 36 cups of water, just divide 36 by 3 to get 12. 12 servings of lemon juice is just right for your 36 cups of water.

Answer: There is 12 servings of lemon juice needed for 36 cups of water.

Step-by-step explanation:

Since we have given that

Number of cups of water to make lemonade = 36

Ratio of lemon juice to water = 1 : 3

So, number of lemon juice cups be x

number of cups of water be 3x.

According to question, it becomes,

[tex]3x=36\\\\x=\dfrac{36}{3}\\\\x=12[/tex]

Hence, there is 12 servings of lemon juice needed for 36 cups of water.

To find the constant 'a' in the function g(x) = 5x + a, you can substitute the known values into the function. Here, it leads us to the equation 5*4 + a = 31. Solving this equation gives 'a' = 11.

The question gives us the value of g(4) and asks us to find the constant 'a' in the function g(x) = 5x + a.

To solve for 'a', we can substitute the known values into the equation. We know that g(4) = 31, and the function g(x) is defined as 5x + a. Therefore, we replace 'x' with 4 in the function. This gives us 5*4 + a = 31.

Solving this equation, we find that 20 + a = 31. By subtracting 20 from both sides of the equation, we can solve for 'a', giving us 'a' = 31 - 20 = 11.

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

Hence y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

In probability, the outcomes of rolling a die are considered. The probability of getting a number less than 7 is 1 or 100% and the probability of rolling a number greater than or equal to 3 is 2/3 or approximately 66.67%

This question falls under the topic of probability in Mathematics. In the case of a single die, there are 6 possible outcomes because a die has 6 faces.

For the probability of getting a number less than 7, all outcomes (1,2,3,4,5,6) are less than 7. Thus, the probability is 6 out of 6 or 1.

For the probability of getting a number that's greater than or equal to 3, the favorable outcomes are 3,4,5,6. So, there are 4 such outcomes. The probability, in this case, is 4 out of 6, which simplifies to 2/3.

ANSWER TO QUESTION 2.

The scale factor is the ratio of the image length to the object length.

[tex]Scale\: factor=\frac{|P'Q'|}{|PQ|}[/tex].

We need to use the distance formula to determine the two lengths.

[tex]|P'Q'|=\sqrt{(3-4)^2+(1-0)^2}[/tex]

[tex]|P'Q'|=\sqrt{(-1)^2+(1)^2}[/tex]

[tex]|P'Q'|=\sqrt{1+1}[/tex]

[tex]|P'Q'|=\sqrt{2}[/tex]

[tex]|PQ|=\sqrt{(6-8)^2+(2-0)^2}[/tex]

[tex]|PQ|=\sqrt{(-2)^2+(2)^2}[/tex]

[tex]|PQ|=\sqrt{4+4}[/tex]

[tex]|PQ|=\sqrt{8}[/tex]

[tex]|PQ|=2\sqrt{2}[/tex]

ANSWER TO QUESTION 3

For a reflection in the y-axis we negate the x-coordinates. That means we are using the y-axis as our mirror line. The mapping is given as follows:

[tex]P'(4,0)\rightarrow P''(-4,0)[/tex]

[tex]Q'(3,1)\rightarrow Q''(-3,1)[/tex]

and

[tex]R(-1,-2)\rightarrow R''(1,-2)[/tex]

ANSWER TO QUESTION 4

We can see from the diagram that, PQR is bigger than P"Q"R".

The reason is that PQR was reduced by scale factor of half and then reflected in the y-axis to obtain P"Q"R".

Since dilation is not a rigid motion, the two triangles PQR and P''Q''R" are not equal in all respect, therefore they are not congruent.

2w + 2l = 25

2 * 2 + 2l = 25

Simplfiy.

4 + 2l = 25

Subtract 4 from both sides.

2l = 21

Divide both sides by 2.

l = 10.5

Now that we have the value of l, we can find the area.

A = lw

A = 10.5 * 2

A = 21.

The length is 10.5cm.

The area of the rectangle is 21cm^2

First, let's convert the radical terms to exponents. Remember the following:

[tex]\sqrt[n]{x^m} = x^\frac{m}{n}[/tex]

[tex]\sqrt{x^5} = x^{\frac{5}{2}}[/tex]

[tex]\sqrt[4]{x^9} = x^{\frac{9}{4}}[/tex]

[tex]\sqrt[6]{x^5} = x^{\frac{5}{6}}[/tex]

After substituting in the values we just found, our expression looks like:

[tex]\dfrac{(x^{\frac{5}{2}})(x^{\frac{9}{4}})}{x^{\frac{5}{6}}}[/tex]

Now, remember that we can add the exponents of terms that have the same base and are being multiplied by each other. Also, remember that we can subtract the exponents of terms with the same base that are being divided by each other. This is represented as:

[tex]x^a \cdot x^b = x^{(a + b)}[/tex]

[tex]\dfrac{x^c}{x^d} = x^{(c - d)}[/tex]

Thus, we can simplify our expression even more:

[tex]\dfrac{(x^{\frac{5}{2}})(x^{\frac{9}{4}})}{x^{\frac{5}{6}}}[/tex]

[tex]\dfrac{x^{\frac{19}{4}}}{x^{\frac{5}{6}}}[/tex]

[tex]x^{\frac{47}{12}}[/tex]

Our answer is [tex]\boxed{m = \dfrac{47}{12}}[/tex].
