To find the value of the tangent of angle P in triangle OPQ, we can use the trigonometric function tangent, which is the ratio of the length of the opposite side to the length of the adjacent side. By substituting the given lengths into the formula, we can calculate the value of tangent to be approximately 0.8989.

In triangle OPQ, we are given that angle Q is a right angle (90 degrees), OQ is 39 units, QP is 80 units, and PO is 89 units. To find the value of the tangent of angle P, we need to use the trigonometric function tangent, which is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Tan(P) = Opposite/Adjacent

In this triangle, the opposite side of angle P is QP and the adjacent side is OP. Therefore, we can substitute the given lengths into the formula:

Tan(P) = 80/89

To find the value of tangent, we can divide 80 by 89 using a calculator or decimal approximation.

Tan(P) ≈ 0.8989 (rounded to the nearest hundredth)

Step-by-step explanation:

whrn you have a proble. you can tell me thank you have a nice day

To solve, find how many groups of 5 are in 145 girls (145 ÷ 5 = 29 groups of girls). Then, find how many boys are in these groups by multiplying the number of groups by the boys' ratio (4), thus 29 x 4 = 116 boys in the 6th grade.

To determine the number of boys in the 6th grade, we will make use of the ratio provided, 4:5. This ratio means that for every 4 boys, there are 5 girls. To translate this into actual numbers, take the total number of girls (145) and calculate how many groups of 5 you have, because that's how many groups of boys you would have also. To determine the number of boys, you multiply the number of groups by 4.

First, Divide 145 by 5 to find out how many groups of girls there are: 145 ÷ 5 = 29. These equate to groups of students based on the ratio. Second, Multiply the number of groups by the boys’ ratio number (4) to find the number of boys. So, 29 x 4 = 116. That's the total number of boys in the 6th grade.

Answer:

y = - 5x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5 and c = - 6, thus

y = - 5x - 6 ← equation in slope- intercept form

The slope intercept form is y = -5x-6

Given, y-intercept = (0, -6) & slope of the line = -5

The general form of an equation of line is, y = mx+c

where, m is the slope of the line & c is the y intercept

So, when x = 0 , y = -6

So, the line above passes through the point (0, -6)

Therefore, The slope intercept form is, y = -5x-6

The equation to solve how many boxes of candy Mr. Hermans's class needs to sell to reach their goal of $500 is 2.75C = 500. To solve for C (number of boxes), divide 500 by 2.75.

In order to figure out how many boxes of candy Mr. Hermans's class needs to sell, you can create an algebraic equation using your known values. Here you know that for each box of candy sold, the class earns $2.75 (represented in our equation as 2.75C) and that their fundraising goal is $500. This sets up the equation as 2.75C = 500. To solve this equation and find the number of boxes needed (represented by 'C'), you would divide each side of the equation by 2.75, which gives you C = 500 / 2.75.

The perimeter of a square is four times the side, since you have to sum all sides, and they're all the same length:

[tex]P=n+n+n+n=4n[/tex]

This is direct variation, because we have

[tex]P=4n \iff \dfrac{P}{n}=4[/tex]

and if the ratio between two variables is constant (in this case, 4), then the two variables are in direct variation.

The perimeter of a square is directly proportional to its side length, therefore it's an example of direct variation.

Yes, the perimeter (P) of a square with side length (n) is an example of direct variation. In this case, P is directly proportional to n. To understand this, think of a square. A square has four equal sides. Thus, its perimeter (P) is n times 4, or P = 4n. If n is increased, the perimeter also increases proportionally, which supports that it's a direct variation relationship. A change in one quantity leads to a proportional change in the other one.

Final answer:

To simplify 2.4 times 10¹³ divided by 8 times 10⁷, subtract exponents to get 2.4 times 10⁶, or adjust the numerator and divide by 8 to find 3 times 10⁵ as the result to perform the calculation mentally.

Explanation:

When dealing with the division of expressions involving powers of ten, using exponent subtraction is often useful to simplify the problem. For the expression 2.4 times 10¹³ divided by 8 times 10⁷, one approach is to directly subtract the lower exponent from the higher one, yielding 2.4 times 10¹³⁻⁷, which simplifies to 2.4 times 10⁶. However, to perform in my head, an alternative way is to adjust the numerator by dividing it by 8, which results in 0.3 times 10¹³. Moving the decimal point in the numerator gives 3 times 10¹², and then dividing by 10⁷ gives a final result of 3 times 10⁵.

first off, those two points above do not give that point-slope form, however, the issue is just what's the standard form.

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

[tex]\bf y+1=\cfrac{2}{3}(x-8)\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y+1)=3\left( \cfrac{2}{3}(x-8) \right)}\implies 3y+3=2(x-8) \\\\\\ 3y+3=2x-16\implies 3y=2x-19\implies -2x+3y=-19 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 2x-3y=19~\hfill[/tex]

The equation of the line that passes through the points (8,1) and (2,-5) in standard form is 2x - 3y = 13.

To find the equation of the line that passes through the given points we need to understand the slope (rise over run) and the y-intercept. The provided equation, y + 1 = 2/3(x - 8), is in point-slope form (which is y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line). To transform to the standard form, we distribute the 2/3 on the right side, subtract 1 from both sides to move y to the left side.

Following these steps, we get: 2x - 3y = 13, as the equation of the line in the standard form.

If we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Step-by-step explanation:

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object.

We can find axis of symmetry with the help of formula:

x = -b/2a

We know that the quadratic equation is written like:

ax^2+bx+c

where a,b are coefficients: c is constant term and x is variable

Now look at the function f(x)= 3x^2

For this function we have a= 3, b =0 , c=0

Put the values in the above mentioned formula:

x = -b/2a

x = - (0)/2(3)

x = 0/6 = 0

Thus the axis of symmetry for f(x) = 0

Now  g(x) = x2 - 4x + 5

a = 1 , b = -4 , c =5

x = -b/2a

x = -(-4)/2(1)

x = 4/2

x = 2

Axis of symmetry for g(x) = 2

h(x) = -2x2 + 4x + 1

a = -2 , b =4 , c=1

x = -b/2a

x = -(4)/2 (-2)

x = -4 /-4

x = 1

Axis of symmetry for h(x) = 1

So if we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Answer:it will be -18 gallons

Step-by-step explanation:

Answer:

482 gallons

Step-by-step explanation:

if the total amount in the pool is 500 gallons and it is leaking at -3 gallons per hour then we can solve for how much it has lost in 6 hours by using this equation:

-3(amount loss per hour) x 6(number of hours)= -18

Now we do 500(total)-18(amount lost in 6 hours)= 482 gallons

Which means there are 482 gallons of water left after 6 hours.

Answer:

Step-by-step explanation:

-3.3m = -1.1

Divide both sides by -3.3

m = -1.1

-3.3

The solution to the equation -3.3m = -1.1 is m = 1/3 or approximately 0.33. This was determined by dividing both sides of the equation by -3.3.

The problem -3.3m = -1.1 is a simple one-step equation which can be solved by isolating the variable. Here the variable is m. Dividing both sides of the equation by -3.3, we get m = (-1.1/-3.3). This simplifies to m = 1/3 ≈ 0.33. So, the solution to the equation is m = 0.33.

What we did here is an application of the principle that whatever you do to one side of an equation, you should do to the other side as well. This principle is essential in solving mathematical equations.

= 7.5 * 6 = 45 Miles

Final answer:

To find the distance traveled by the bicycle rider, multiply the average speed of 7.5 mph by the time of travel of 6 hours, resulting in a total distance of 45 miles.

Explanation:

Calculating Distance Traveled

To calculate the distance traveled by the bicycle rider, we use the formula that relates average speed, distance traveled, and time of travel:

Average speed = Distance traveled / Time of travel

In this scenario, the bicycle rider's average speed is given as 7.5 mph, and the time of travel is 6 hours. Therefore, the distance traveled can be calculated by multiplying the average speed by the time of travel:

Distance traveled = Average speed × Time of travel

Distance traveled = 7.5 mph × 6 h = 45 miles

Therefore, the bicycle rider traveled a total of 45 miles.
