HELP ME PLEASE ITS DUE IN 1 HOUR I'VE BEEN DOING MY HOMEWORK FOR 5 HOURS WITH NO BREAKS

Answer:

130 minutes

Step-by-step explanation:

They watched 50% of movie, means 50% left unwatched

Remaining length = 65 minutes = 50% of movie

Movie length = 65 *2 = 130 minutes

By solving a percentage equation, we will see that the initial amount is $142.70

If we have an amount A, and we reduce it by X (where X is a percentage) then the new value is:

V = A*(1 - X/100%)

In this case, we know that the percentage reduced is 19.4%, and the new value is $115, replacing these values we will get:

$115 = A*(1 - 19.4%/100%)

Now we can solve that equation for A.

$115 = A*(1 - 19.4%/100%)

$115 = A*(0.806)

$115/(0.806) = A

$142.70 = A

The original value was $142.70

Answer: y=3.75x+1.9

Step-by-step explanation: the pick up fee would be the y-intercept and the per mile cost would be the slope.

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Pick up fee charges = $1.90

Charges per mile = $3.75

Total fare = $80.65

The number of miles traveled = x

We can write an equation as:

1.90 + 3.75x = 80.65

The number of miles traveled:

1.90 + 3.75x = 80.65

Subtract 1.90 on both sides.

1.90 + 3.75x - 1.90 = 80.65 - 1.90

3.75x = 78.75

Divide both sides by 3.75.

x = 21.

Thus,

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

Step-by-step explanation:

Based on the information given, we have a diagram with two sides labeled as 13.3 mm and 5.5 mm, and another side labeled as X mm.

To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.

Perimeter = 13.3 mm + 5.5 mm + X mm

The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.

To find X, we can subtract the sum of the known sides from the perimeter:

X mm = Perimeter - (13.3 mm + 5.5 mm)

Since the value of X is not given, we cannot calculate it without the perimeter value. If you provide the perimeter value, I can help you find the length of X.

Based on the cross-price elasticity of Demand, we can conclude that good X and good Y are substitutes.

Let's calculate the cross-price elasticity of demand using the given information:

a. Find the percentage change in quantity demanded of good Y:

Percentage Change in Quantity Demanded of Good Y = (New Quantity Demanded - Initial Quantity Demanded) / Initial Quantity Demanded * 100

Percentage Change in Quantity Demanded of Good Y = (6250 - 5000) / 5000 * 100 = 25%

b. Find the percentage change in the price of good X:

Percentage Change in Price of Good X = (New Price - Initial Price) / Initial Price * 100

Percentage Change in Price of Good X = (5 - 4) / 4 * 100 = 25%

Now, we can calculate the cross-price elasticity of demand:

Cross-Price Elasticity of Demand = Percentage Change in Quantity Demanded of Good Y / Percentage Change in Price of Good X

Cross-Price Elasticity of Demand = 25% / 25% = 1

b. Based on the calculated cross-price elasticity of demand, we can determine the types of goods:

If the cross-price elasticity of demand is positive (as in this case, where it is 1), it indicates that the two goods are substitutes. This means that when the price of good X increases, the quantity demanded of good Y also increases, suggesting that consumers view these goods as alternatives to each other.

Therefore, based on the cross-price elasticity of demand, we can conclude that good X and good Y are substitutes.

Answer:

22° + m<C = 90°

Step-by-step explanation:

We are given that <A (which is equal to 22°) and <B are vertical angles, and that <B is complementary to <C.

We want to write an equation that will help us solve <C.

Recall that vertical angles are congruent by vertical angles theorem.

This means that <A ≅ <B; it also means that the measure of <B is also 22°.

Also recall that complementary angles add up to 90°.

This means that m<B + m<C = 90°.

Since we deduced that m<B is 22°, we can substitute that value into the equation.

Hence, an equation that can be used to solve for <C is:

22° + m<C = 90°

Answer: PLATO/Edmentum

Step-by-step explanation:

The equation that best represents the relationship between x and y is:

y = -1/2x + 11

To determine the equation that best represents the relationship between the quantities x and y, we can examine the pattern in the table.

Looking at the x-values and their corresponding y-values, we can observe that as x increases by 2 units, y decreases by 1 unit.

Using this pattern, we can find the equation that represents the relationship.

When x = 2, y = 10

When x = 4, y = 9

When x = 6, y = 8

When x = 8, y = 7

Based on the pattern, we can see that y decreases by 1 unit for every 2 units increase in x.

Therefore, the equation that best represents the relationship is:

y = -1/2x + b

To find the value of b (the y-intercept), we can substitute the values of x and y from any point in the table. Let's use the first point (x = 2, y = 10):

10 = -1/2(2) + b

10 = -1 + b

b = 11

So the equation that best represents the relationship between x and y is:

y = -1/2x + 11

Therefore, the correct answer is: y = -1/2x + 11.
