Answer:

  MN = 50

Step-by-step explanation:

You want the length of the base segment MN in triangle MNO, where MN is marked 41+3x and parallel midsegment PQ is marked 49-8x.

The midsegment is half the length of the parallel base segment. That means the base segment is double the length of the midsegment:

  MN = 2·PQ

  41 +3x = 2(49 -8x)

  41 +3x = 98 -16x

  19x = 57 . . . . . . . . add 16x-41

  x = 3

  MN = 41 +3x = 41 +3·3 = 50

The length of MN is 50 units.

The values of a and b in the expression x³ + ax³ + bx - 3 are a = 1 and b = -17

From the question, we have the following parameters that can be used in our computation:

x^3+ax^3+bx-3

Rewrite properly

So, we have

x³ + ax³ + bx - 3

The expression has a factor of x - 3

This means that

(3)³ + a(3)³ + b(3) - 3 = 0

So, we have

27 + 27a + 3b - 3 = 0

Evaluate the like terms

27a + 3b = -24

Divide by 3

9a + b = -8

The expression has a remainder of 15 when divided by x + 2

This means that

(-2)³ + a(-2)³ + b(-2) - 3 = 15

So, we have

-8 - 8a - 2b - 3 = 15

Evaluate the like terms

-8a - 2b = 26

Divide by -2

4a + b = -13

So, we have

9a + b = -8

4a + b = -13

Subtract the equations

5a = 5

Divide

a = 1

Recall that 4a + b = -13

So, we have

4(1) + b = -13

So, we have

b = -13 - 4

Evaluate

b = -17

Hence, the values are 1 and -17

Answer:

the slope is 0.5 or 1/2

Step-by-step explanation:

3x - 6y = 90

-6y = -3x + 90

y = 0.5x + 90

Answer:

slope= 1/2

Step-by-step explanation:

3x-6y=90

rewrite the equation into slope intercept form

y=1/2x-15

subtracting is the same as adding the opposites

y=1/2x+(-15)

since the equation is written in slope intercept form, y=mx+b, identify the slope of the line as the coefficient next to the variable x

y=1/2x+(-15), m=1/2

identify the y intercept of the lines as the constant term

y=1/2x+(-15),m(slope)=1/2,b=-15

The inequality best represents the possible ways the team can score more than 60 points.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

Given that, the Mid-High JV Team is playing in the state championship for football.

In order to beat their all-time points in a season record, they need to score more than 60 points in the game.

Considering a field goal (f) scores 3 points, a touchdown (t) scores 6 points, and a touchdown with an extra point (p) scores 7 points.

We need to find the inequality best represents the possible ways the team can score more than 60 points.

3f+6t+7p>60

Hence, 3f+6t+7p>60 is the inequality best represents the possible ways the team can score more than 60 points.

To find the distance from the ranger's station to the forest fire, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the forest fire, the height of the ranger's station above the ground, and the distance from the ranger's station to the forest fire to form a right triangle.

We can then use the tangent function to find the distance from the ranger's station to the forest fire as follows:

tan(35°) = opposite/adjacent

opposite = tan(35°) * adjacent

opposite = tan(35°) * 100 feet

opposite = 0.7392 * 100 feet

opposite = 73.92 feet

Therefore, the distance from the ranger's station to the forest fire is approximately 74 feet. To the nearest tenth of a foot, this is 73.9 feet.

Step-by-step explanation:

You want examples of use of the rules of logarithms:

  [tex]\begin{array}{ll}\vphantom{\dfrac{M}{gN}}1.&\log_b{(MN)}=\log_b{(M)}+\log_b{(N)}\\2.&\log_b{\left(\dfrac{M}{N}\right)}=\log_b{(M)}-\log_b{(N)}\\\vphantom{\dfrac{b}{g}}3.&\log_b{(M^a)}=a\cdot\log_b{(M)}\end{array}[/tex]

The point of these is that M and N and 'a' and 'b' can be anything. (Generally, 'b' will be a positive number greater than 1.) For the purpose here, we can let M ∈ {x^3y, (1+r)}, N ∈ {(x-4), r/n}, a ∈ {4, -3}, b ∈ {2, e}.

Using these values in various combinations, your examples could be ...

  [tex]\log_2{((x^3y)(x-4))}=\log_2{(x^3y)}+\log_2{(x-4)}\\\\\ln{((1+r)(r/n))}=\ln{(1+r)}+\ln{(r/n)}\\\\ \log_2{((x^3y)(r/n))}=\log_2{(x^3y)}+\log_2{(r/n)}[/tex]

Answer:

8

Step-by-step explanation:

The number 80 is called the numerator or dividend, and the number 9 is called the denominator or divisor.

The quotient (integer division) of 80/9 equals 8; the remainder (“left over”) is 8.

80 is the dividend, and 9 is the divisor.

By using proportionality, it can be calculated that-

a) Constant of proportionality that relates the length of paver in the model and the actual length is k = [tex]\frac{4}{3}[/tex]

[tex]y = \frac{4}{3}x[/tex] is the required equation which relates the length of paver in the model and the actual length of the paver

b) Area of the rectangle = [tex]\frac{1}{3}[/tex] sq.feet

Constant of proportionality that relates the area of paver in the model and the actual area is k = [tex]\frac{9}{16}[/tex]

What is proportionality?

Suppose there are two quantities. Proportionality indicates that if there is a change in the value of one quantity, the value of other quantity also changes but maintaining a constant ratio

Proportionality can be direct or inverse

Direct proportion

Two quantities are said to be in direct proportion if on increasing the value of one quantity, the value of other quantity also increases and vice versa.

For example cost of a commodity and quantity of a commodity are in direct proportion

Inverse proportion

Two quantities are said to be in inverse proportion if on increasing the value of one quantity, the value of other quantity decreases and vice versa.

For example Number of men and number of days taken by those men to complete a job.

Length of paver in the model = [tex]\frac{2}{3}[/tex] ft

Actual length of paver = [tex]\frac{1}{2}[/tex] ft

Let the constant of proportionality be k

[tex]\frac{2}{3} = \frac{1}{2}k[/tex]

k = [tex]\frac{2}{3} \div \frac{1}{2}[/tex]

k = [tex]\frac{4}{3}[/tex]

Let y be the length of paver in the model and x is the actual length

[tex]y = \frac{4}{3}x[/tex] is the required equation which relates the length of paver in the model and the actual length of the paver

b) Area of the model = [tex]\frac{1}{2}\times \frac{3}{8} = \frac{3}{16}[/tex] sq. feet

Actual area = [tex]\frac{2}{3} \times \frac{1}{2} = \frac{1}{3}[/tex] sq.feet

Let the constant of proportionality be l

[tex]\frac{3}{16} = \frac{1}{3}l[/tex]

l = [tex]\frac{3 \times 3}{16}\\[/tex]

l = [tex]\frac{9}{16}[/tex]

By cross multiplication, the result for each pair of rational numbers are listed below:

Cross multiplication is a property involving multiplication and division between the terms of two rational numbers of the form:

a / b = c / d

Where a, b, c, d are real numbers. Combinations between a numerator and a denominator are multiplications and combinations between two numerators and two denominators are divisions. Now we proceed to solve on each case:

Case 11

4 / x = 2 / 7

4 · 7 = 2 · x

28 = 2 · x

x = 14

Case 12

19 / 10 = x / 12

19 · 12 = 10 · x

228 = 10 · x

x = 114 / 5

Case 13

(x - 1) / 6 = 13 / 19

(x - 1) · 19 = 13 · 6

(x - 1) · 19 = 78

x - 1 = 78 / 19

x = 1 + 78 / 19

x = 97 / 19

Case 14

5 / 17 = 19 / (x + 4)

5 · (x + 4) = 19 · 17

x + 4 = 323 / 5

x = 318 / 5

Case 15

10 / (2 · x - 9) = 20 / 9

10 · 9 = 20 · (2 · x - 9)

90 / 20 = 2 · x - 9

27 / 2 = 2 · x

27 / 4 = x

x = 27 / 4

Case 16

12 / 18 = (3 · x + 4) / 15

2 / 3 = (3 · x + 4) / 15

10 = 3 · x + 4

3 · x = 6

x = 2

Case 17

(x - 20) / 3 = (x - 11) / 18

18 · (x - 20) = 3 · (x - 11)

18 · x - 360 = 3 · x - 33

15 · x = 327

x = 109 / 5

Case 18

6 / (x + 16) = 7 / (3 · x + 3)

6 · (3 · x + 3) = 7 · (x + 16)

18 · x + 18 = 7 · x + 112

Answer:

$337.50

Step-by-step explanation:

To find the total cost of the uniforms, you will need to find the unit price of the shirts and the unit price of the shorts and then multiply each by the number of shirts and shorts, respectively.

The unit price of the shirts is the total cost divided by the number of shirts, or $180 / 15 shirts = 12/shirt.

The unit price of the shorts is

$12/shirt - $1.50/shirt = 10.5/shirt.

Since the coach bought the same number of shirts and shorts, the total number of shirts and shorts is 15 shirts + 15 shorts = 30 shirts and shorts.

The total cost of the shirts is $12/shirt * 15 shirts = $12*15 = 180.

The total cost of the shorts is $10.5/shirt * 15 shirts = 157.5

The total cost of the uniforms is the sum of the cost of the shirts and the cost of the shorts, or $180 + 157.5= 337.5.

Therefore, the total cost of the uniforms for the team is $337.5.
