Chris will take the train to willow lake. The train goes 60 miles an hour. If Chris takes the 2:20 train, about what time will he get to willow lake?

Answers

Answer 1

If Chris takes the 2:20 train, then he will get to willow lake at 2:28.

If Chris takes the 2:20 train, then we have to find at what time he will get to willow lake.

The distance from where Chris lives to willow lake is 48 miles.

Chris will take the train to willow lake. The train goes 60 miles an hour.

The distance = 48 miles

The speed of train = 60 miles an hour

Time = distance/speed

Time = 48/60

Time = 0.8 minutes

The train reach after 8 minutes in willow lake.

So the train reach 2:28.

Which of the following statements is true about the triangles below

Answers

Answer: ASA

Step-by-step explanation: Hello! You can use ASA to prove that the triangles ABC and ABD are congruent.  This is because you are given two angles of each triangle.  You know that your answer should be ASA or AAA, which are the only two triangle congruence postulates that involve two or more congruent angles.  Lastly, you can use the reflexive property.  An example of reflexive property is 3 = 3, which means anything is congruent to itself.  You know that both triangles share line segment AB, meaning that they have one side and two angles that are congruent.  Since you know that the two angles and the included side are congruent, ASA proves that both triangles ABC and ABD are congruent.  I hope this helps you!

On a​ team, 3 girls and 2 boys scored a total of 27 points. The difference between the number of points scored by the 3 girls and the number of points scored by the 2 boys is 15. Each girl scored the same number of points, and each boy scored the same number of points. Find the number of points scored by each girl and each boy.

Answers

Answer:

We can start solving the problem by using algebra. Let x be the number of points scored by each girl, and y be the number of points scored by each boy. Then, based on the information given in the problem, we have the following equations:

x + y = 27 (the total number of points scored by the team)

3x - 2y = 15 (the difference between the number of points scored by the 3 girls and the 2 boys)

To solve for x and y, we can use the second equation to eliminate one of the variables. Multiplying both sides of the second equation by 2, we get:

6x - 4y = 30

Now we can substitute this into the first equation:

6x - 4y + y = 27

6x = 27 + 4y

x = (27 + 4y)/6

Now we can substitute this back into the second equation:

3((27 + 4y)/6) - 2y = 15

27 + 2y - 2y = 15

27 = 15

This is a contradiction, so the given information is insufficient to find the number of points scored by each girl and each boy.

Find the measure of angles 1 and 2

Answers

Answer:

angle 1 = 118 deg

angle 2 = 62 deg

Step-by-step explanation:

To find angle one you must know that angles 1 and 118 deg are alternate angles. Therefore since these lines are parallel, angles 1 and 118 are equal.

To find angle 2 to you must know that angle 1 + angle 2 = 180.

angles on a straight line always equal 180 deg

therefore:

180

118 -

62 deg

hope this helps :)

Answer:

m<1 = 118°

m<2 = 62°

Step-by-step explanation:

The horizontal lines are parallel.

Angles 1 and 118° are alternate interior angles of parallel lines cut by a transversal, so they are congruent.

m<1 = m<2 = 118°

Angles 1 and 2 are a linear pair, so they are supplementary. That means that their measures add to 180°.

m<1 + m<2 = 180°

118° + m<2 = 180°

m<2 = 62°

Mary, Ana, and Nata work at a coffee shop. Each day from Monday to Friday exactly two of them come to work. Mary works 3 days per week and Ana works 4 days per week. How many days per week does Nata work?

Answers

Based on the information, it can be inferred that Nata has to work 7 days a week.

How to calculate how many days Nata works?

To calculate how many days Nata works we must perform the following mathematical operation.

We must find how many days in total Ana and Mary work together, that is, we must add the days that they work.

3 + 4 = 7

Based on the above, we can say that Ana and Mary work 7 days a week, so Ana could work Monday, Tuesday and Wednesday and Mary could work Thursday, Friday, Saturday and Sunday.

Lenny has 104 coins in his pocket made up of nickels and dimes worth
$22.00. Write and solve a system of equations to find out how many
nickels and quarters he has.

Answers

On solving the equations x + y = 104 and 0.05x + 0.25y = 22, the number of nickels and quarters Lenny has is 20 and 84 respectively.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The value of 1 nickel is = $0.05

The value of 1 quarter is = $0.25

The total amount of coins is = $22.0

The total number of coins is = 104

Let the number of nickel be = x

Let the number of quarter be = y

The equation for total number of coins =

x + y = 104 ....(1)

The equation for total amount of coins =

0.05x + 0.25y = 22 ...(2)

Multiply equation (1) by 0.05 -

0.05(x + y) = 104 × 0.05

0.05x + 0.05y = 5.2 ... (3)

Subtracting equation (3) from (2) -

0.05x + 0.25y - (0.05x + 0.05y) = 22 - 5.2

0.05x + 0.25y - 0.05x - 0.05y = 22 - 5.2

0.20y = 16.8

y = 84

Substitute the value of y in equation (1) -

x + 84 = 104

x = 104 - 84

x = 20

Therefore, the value for x and y is obtained as x = 20 and y = 84.

Your parents are taking you and some of your friends to the movies tonight. Your parents might bring your grandparents and other adults to the movies as well. Adult tickets cost $11 each, and children's tickets cost $8 each. Write an equation that represents the total cost for the movie tickets. What is one combination of tickets that would total $57?

Answers

Answer:

57 = 33+24 = 3a+3c

Step-by-step explanation:

Let a= adults, c = children

total costs = 11a+8c

57 = 33+24 = 3a+3c

Answer: We can use the variables x and y to represent the number of adult tickets and children's tickets, respectively. The cost of adult tickets is $11 each and the cost of children's tickets is $8 each. So, we can use the following equation to represent the total cost for the movie tickets:

C = 11x + 8y

Where C is the total cost of the tickets, x is the number of adult tickets and y is the number of children's tickets

One combination of tickets that would total $57 is:

C = 11x + 8y = $57

x + y = 7 (number of tickets)

One way to satisfy this equation is to have 5 adult tickets and 2 children's tickets

x = 5

y = 2

C = 115 + 82 = $57

So, 5 adult tickets and 2 children's tickets is one combination that would total $57.

If 479,000 people each receive an average refund of $4,500, based on an interest rate of 1 percent, what would be the lost annual income from savings on those refunds? (Do not round intermediate calculations. )

Answers

As per the compound interest, the lost annual income from savings on those refunds is $21,555,000

In math the term called compound interest is defined as a type of interest that not only accrues on the principal but also on the accrued interest and the interest rates on loans are quoted in terms of annual percentage rate, which does not account for the compounding of interest, and therefore understates the true cost of borrowing.

Here we know that the 479,000 people each receive an average refund of $4,500, based on an interest rate of 1 percent.

Then the lost annual income from savings on those refunds is calculated as,

As we all know that the lost annual income is the amount of interest these people could have earned on their income, in which  the extra tax had not been deducted.

Then With $4,500 each person,

Then the total amount of the deducted income is calculated as,

=> 479,000 x 4,500 = 2,155,500,000.

Here we have the  1% interest rate, then the net return on these fund if they were saved

=> 2,155,500,000 x 1% = 21,555,000.

Therefore the total lost annual income is 21,555,000

Define the term slope of the line?

Slope, usually referred to as rise over run, is the "steepness" of the line.

By dividing the difference in y values between two points by the difference in x values, we may determine slope.

A line's slope does not summarily characterize it. As a result, even if you know a line's slope, you cannot identify the exact spots the line passes through.Any two lines with the same slope are said to be parallel. When a line is rotated 90 degrees, it becomes perpendicular and becomes parallel. A horizontal line is one that has a slope of 0. Positive lines are those that rise as they move further to the right.The y-axis is an example of a vertical line that is believed to have an "undefined" slope.

Thus, as the line is passing through the y axis and parallel to the x axis, the slope of the given line is undefined.

Answers

If heights of a species of plant are approximately Normally distributed, have a mean of 9.31 cm, and standard deviation of 0.55 cm , If 20 of the plants are randomly selected , then the probability that the mean plant height is less than 9.5 cm is 0.9388  .

We can use the Z-score formula to find the probability that a randomly selected plant has a height less than 9.5 cm:

Z  = (x - mean)/(standard deviation/sqrt(sample size))  ;

Where x is the value we want to find the probability for, in this case x = 9.5

So , Z = (9.5 - 9.31)/(0.55/√20) = (0.19)/(0.123) = 1.54

Now we can use the standard normal table to find the probability that a Z-score is less than 1.54  .

From the z table ; we get , the p value is 0.9388  .
