Scott and his family went on a backpacking trip. They started hiking at 3:00 P.M. It took 1 hour and 55 minutes to reach their campsite. After they arrived, it took 1 hour and 10 minutes to set up the campsite. What time was it when Scott and his family finished setting up their campsite?

Answer:

  12.5°

Step-by-step explanation:

In any triangle, an exterior angle is the sum of the remote interior angles.

The exterior angle at the vertex angle of an isosceles triangle will be the sum of the two congruent base angles. Hence, each base angle is half the value of the exterior angle.

  25° = 2b

  b = 25°/2 = 12.5° . . . . the measure of each base angle

y = 2x-8

========================================================

Explanation:

Let's find the slope of the line through (2,7) and (4,11).

[tex](x_1,y_1) = (2,7) \text{ and } (x_2,y_2) = (4,11)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{11 - 7}{4 - 2}\\\\m = \frac{4}{2}\\\\m = 2\\\\[/tex]

The slope is 2.

Any line parallel to this current line will have the same slope, but different y intercept.

Choice B has the same slope (2), so this is why it's the final answer.

[tex] \qquad \sf  \dashrightarrow \: 4(5x - 2) = 2(9x + 3)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 20x - 8 = 18x + 6[/tex]

[tex]\qquad \sf  \dashrightarrow \: 20x - 18x = 6 + 8[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 14 \div 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 7[/tex]

Therefore value of x is 7

By solving the linear equation, we will see that the solution is x = 7.

Here we need to solve the equation:

[tex]4*(5x - 2) = 2*(9x + 3)[/tex]

First, we should distribute the two products to get:

[tex]4*5x - 4*2 = 2*9x + 2*3\\\\20x - 8 = 18x + 6[/tex]

Now we move the terms with x to the left, and the terms without x to the right.

[tex]20x - 8 = 18x + 6\\\\20x - 18x = 6 + 8\\\\2x = 14\\\\[/tex]

Now we can divide both sides by 2 to get:

[tex]x = 14/2 = 7\\x = 7[/tex]

So the solution of the linear equation is x = 7.

Step-by-step explanation:

Answer:

the answer is $8.29

Step-by-step explanation:

1.60 marked up by 60% in decimal form is .60

multiply that .60 by 1.60 and you get .64

you add .64 to 1.60 and you get 2.56

you multiply 2.56 by 3 and you get 7.68

you have a 8% sales tax so you multiply 0.08 by 7.68

you will get .61 you add that to 7.68 to get $8.29

Answer:

$2.05 × 3 is $6.15

therefore adding sales tax would make it $6.64

Answer:

h = 6 hours, A = $210

Step-by-step explanation:

The equation for Lady Luck Limousine's (LLL) total amount is A = 25h + 60, where h represents the hours.

The equation for Street Scene Limousine's (SSL) total amount is A = 35h.

To find the point at which the two services would be equal, we can use the equation 25h + 60 = 35h.

Solving for h = 6.

When we plug in 6 into either one of the equations, we get $210.

Answer:

x=12

y=6

Step-by-step explanation:

Let's first start by moving x and y to one side (I prefer having both variables on the same side and the other number on the other side):

3x-y=30

-3x+7y=6

Add the equations to eliminate x

6y=36

Divide both sides by 6

y=6

3x-30=6

Add 30 to both sides

3x=36

Divide both sides by 3

x=12

(x,y)=(12,6)

Answer:

x = -3.25

Step-by-step explanation:

2/5 = 0.4

0.4x - 0.2 = -2(3/4)

-2(3/4) = -2/1 * 3/4 = -6/4

0.4x - 0.2 = -6/4

Convert to fraction

2/5x - 1/5 = -6/4

Add 1/5 to both sides

-6/4 + 1/5 = -30/20 + 4/20 = -26/20

2/5x = -26/20

Convert to decimal

0.4x = -1.3

-1.3/0.4 = -3.25

x = -3.25

Proportional relationship are used to represent direct variations.

The equation that represents the proportional relationship is [tex]y = \frac{28}{17}x[/tex]

From the question,

When x = 34, y = 56

So, the proportionality constant (k) is calculated as:

[tex]k = \frac yx[/tex]

This gives

[tex]k = \frac {56}{34}[/tex]

Reduce the fraction

[tex]k = \frac {28}{17}[/tex]

The proportional relationship is then calculated as:

[tex]y = kx[/tex]

Exponential functions are functions defined by y = ab^x, where a represents the initial value, and b represents the rate

The initial population of the city is 10000, and the growth rate of the population is 4%.

So, the exponential equation is:

[tex]y = 10000 * 1.04^x[/tex]

The initial population of the city is 12000, and the decay rate of the population is 3%.

So, the exponential equation is:

[tex]y = 12000* 0.97^x[/tex]

The similarity in both equations is that, they both represent exponential function.

In (a) and (b), we have:

[tex]y = 10000 * 1.04^x[/tex] ---- city A

[tex]y = 12000* 0.97^x[/tex] --- city B

When city A exceeds city B, we have the following inequality

[tex]10000 * 1.04^x > 12000 * 0.97^x[/tex]

Divide both sides by 10000

[tex]1.04^x > 1.2 * 0.97^x[/tex]

Divide both sides by 0.97^x

[tex](\frac{1.04}{0.97})^x > 1.2[/tex]

[tex]1.07^x > 1.2[/tex]

Take the natural logarithm of both sides

[tex]\ln(1.07)^x > \ln(1.2)[/tex]

This gives

[tex]x\ln(1.07) > \ln(1.2)[/tex]

Solve for x

[tex]x > \frac{\ln(1.2)}{\ln(1.07)}[/tex]

[tex]x > 2.69[/tex]

This means that, the population of city A will exceed city B after 3 years

In (a) and (b), we have:

[tex]y = 10000 * 1.04^x[/tex] ---- city A

[tex]y = 12000* 0.97^x[/tex] --- city B

When city A is at least twice city B, we have the following inequality

[tex]10000 * 1.04^x \ge 2 * 12000 * 0.97^x[/tex]

[tex]10000 * 1.04^x \ge 24000 * 0.97^x[/tex]

Divide both sides by 10000

[tex]1.04^x \ge 2.4 * 0.97^x[/tex]

Divide both sides by 0.97^x

[tex](\frac{1.04}{ 0.97})^x \ge 2.4[/tex]

[tex]1.07^x \ge 2.4[/tex]

Take the natural logarithm of both sides

[tex]\ln(1.07)^x \ge \ln(2.4)[/tex]

This gives

[tex]x\ln(1.07) \ge \ln(2.4)[/tex]

Solve for x

[tex]x\ge \frac{\ln(2.4)}{\ln(1.07) }[/tex]

[tex]x\ge 12.9[/tex]

This means that, the population of city A will be at least twice city B after 13 years

If c is a constant, then

E[X - c] = E[X] - E[c]

… = E[X] - c

and

E[(X - c)²] = E[X² - 2cX + c²]

… = E[X²] - 2c E[X] + E[c²]

… = E[X²] - 2c E[X] + c²

Recall the definition of variance:

Var[X] = E[(X - E[X])²]

… = E[X² - 2X E[X] + E[X]²]

… = E[X²] - E[2X E[X]] + E[E[X]²]

… = E[X²] - 2E[X] E[X] + E[X]²

… = E[X²] - E[X]²

The standard deviation of X is 3.2, so Var[X] = 3.2² = 10.24.

By this definition,

Var[X - c] = E[(X - c)²] - E[X - c]²

but again because c is constant,

Var[X - c] = Var[X]

This is because

Var[X - c] = E[(X - c)²] - E[X - c]²

… = E[X² - 2cX + c²] - (E[X] - E[c])²

… = E[X²] - 2c E[X] + E[c²] - E[X]² + 2 E[X] E[c] - E[c]²

… = (E[X²] - E[X]²) - 2c E[X] + E[c]² + 2c E[X] - E[c]²

… = Var[X]

Then

10.24 = 3099.2 - E[X - c]²

⇒   E[X - c]² = 3088.96

⇒   E[X - c] = 55.5784
