BC Is Parallel To DE.what Is The Length Of CE?

Answers

Answer 1

Answer:

Option B [tex]2\frac{2}{3}\ units[/tex]

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and ADE are similar by AA Similarity Theorem

so

[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]

substitute the given values

[tex]\frac{3}{3+2}=\frac{4}{AE}[/tex]

Solve for AE

[tex]\frac{3}{5}=\frac{4}{AE}[/tex]

[tex]AE=5(4)/3[/tex]

[tex]AE=\frac{20}{3}\ units[/tex]

Find the length of CE

[tex]AE=AC+CE\\CE=AE-AC[/tex]

substitute the values

[tex]CE=\frac{20}{3}-4[/tex]

[tex]CE=\frac{8}{3}\ units[/tex]

Convert to mixed number

[tex]\frac{8}{3}\ units=\frac{6}{3}+\frac{2}{3}=2\frac{2}{3}\ units[/tex]

Answers

Answer:

Step-by-step explanation:

y ≤ x − 5

1<10-5

1<5

Pair: (10,1)

y ≤ −x − 4

-10<-1-5

-10<-6

Pair: (1,-10)

Answer:

(1, −10)

Step-by-step explanation:

If we graph this system of inequalities, we could find the solution.

From the graph you can deduct that the only right answer is the last one (1,-10), because the area of solution is only for negative values of y.

Therefore, the right choice is the last one.

If you can't graph, you can try another method. If we replace the value in the system, it should satisfy it, that is, it should gives us a true result like 0<1 for example. Let's try

For x=1 and y=-10, we have

-10 ≤ 1 − 5

-10 ≤ −1 − 4

-10 ≤ -4

-10 ≤ -5

As you can see, the result is true, because -10 is less than -4 and -5, so that's the right answer.

a countey fair charges $7 and $0.75 for each ride token. you have $15 write a exspression that represents the amount (in dollars) you have left after entering the fair and purchasing n tokens. how many tokens can you purchase? how much money do you have after purchasing 6 tokens​

Answers

Answer:

$3.50

Step-by-step explanation:

15.00 - 7.00 = 8.00

6 x .75 = 4.50

8.00- 4.5 = 3.50

The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7  where n is the total number of rides

The amount left after purchasing 6 tokens is $ 3.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be represented as = y

Now , the number of rides be = n

The cost of entry fee = $ 7

The cost for each ride = $ 0.75

The total amount available = $ 15

So , the equation will be

total amount = cost for each ride x number of rides + cost of entry fee

Substituting the values in the equation , we get

Total amount y = 0.75n + 7

y = 0.75n + 7

So , the equation is y = 0.75n + 7

Now , when purchasing 6 tokens , we get the remaining amount as

Substituting the value of n = 6 in the equation , we get

y = 0.75 x 6 + 7

y = 4.5 + 7

y = $ 11.5

So , the amount left = 15 - y

The total amount left = 15 - 11.5

The total amount left = $ 3.50

Hence , The equation for the total amount for the fair and rides is given by the relation y = 0.75n + 7  where n is the total number of rides

The amount left after purchasing 6 tokens is $ 3.50

The sale price of a trampoline before tax is $300 the sales tax is 4% find the sales tax in the total price of the trampoline

Answers

The trampoline will attract a sales tax of $12 which will take its total price to $312.

The trampoline costs $300 without taxes being accounted for yet.

The tax is 4%. In dollar terms this is:

= Sales tax percentage x Cost of trampoline

= 4% x 300

= $12

The total price of the trampoline will therefore be:

= Cost of trampoline + sales tax

= 300 + 12

= $312

In conclusion, the sales tax would be $12 and the total price would be $312.

A school is arranging a field trip to the zoo. The school spends 875.49 dollars on passes for 29 students and 4 teachers. The school also spends 279.56 dollars on lunch for just the students. How much money was spent on a pass and lunch for each student?

Answers

Answer:

Money spent on each student is $36.17

Step-by-step explanation:

$875.49 = 29 students & 4 teachers

33 people = $875.49

1 person = $26.53 (pass)

29 students = $279.56

1 student = $9.64 (lunch)

each student = $9.64 + $26.53

= $36.17

the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.

To find out how much money was spent on a pass and lunch for each student, we need to calculate the total amount spent on passes and lunch and then divide it by the total number of students.

Given:

- Total amount spent on passes for 29 students and 4 teachers: $875.49

- Total amount spent on lunch for just the students: $279.56

- Total number of students: 29

1. First, let's find the total amount spent on passes for just the students:

  Total amount spent on passes for students and teachers = $875.49

  Total amount spent on passes for 4 teachers = ?

  Total amount spent on passes for students = $875.49 - (amount spent on passes for teachers)

  Since each pass costs the same amount for students and teachers, we can divide the total amount spent on passes by the total number of passes (students + teachers) to find the cost per pass.

  Total number of passes (students + teachers) = 29 students + 4 teachers = 33 passes

  Cost per pass = Total amount spent on passes / Total number of passes

                = $875.49 / 33

                ≈ $26.56 (rounded to two decimal places)

2. Now, let's find out how much money was spent on lunch for each student:

  Total amount spent on lunch for students = $279.56

  Cost per student for lunch = Total amount spent on lunch for students / Total number of students

                              = $279.56 / 29

                              ≈ $9.63 (rounded to two decimal places)

So, the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.

How much greater is the house number of the last house on Oak Street than the house
number of the last house on Maple Street

Answers

The last house on Oak Street has a house number 8 greater than the last house on Maple Street.

The correct answer is option C.

Let's denote the house numbers on Maple Street as M1, M2, M3, M4, and M5, where each house number is six more than the one to its left. Similarly, on Oak Street, denote the house numbers as O1, O2, O3, O4, and O5, where each house number is eight more than the one to its left.

For Maple Street:

M2 = M1 + 6

M3 = M2 + 6

M4 = M3 + 6

M5 = M4 + 6

For Oak Street:

O2 = O1 + 8

O3 = O2 + 8

O4 = O3 + 8

O5 = O4 + 8

Now, let's find the difference between the last house on Oak Street (O5) and the last house on Maple Street (M5):

The difference is (O4 + 8) - (M4 + 6) = (O3 + 8 + 8) - (M3 + 6 + 6) = (O2 + 8 + 8 + 8) - (M2 + 6 + 6 + 6) = (O1 + 8 + 8 + 8 + 8) - (M1 + 6 + 6 + 6 + 6).

Simplifying the expression, the constant terms cancel out, leaving:

The difference is O1 - M1 + (8 + 8 + 8 + 8) - (6 + 6 + 6 + 6) = O1 - M1 + 32 - 24 = O1 - M1 + 8.

So, the house number of the last house on Oak Street is 8 greater than the house number of the last house on Maple Street.

Each house number on maple street is six more than the house number to its left. Each house number on oak street is eigth more than the house number to its left.

Answer:

g(x) = |x+3| - 5

Step-by-step explanation:

Let y = f(x)

⇒y = |x+3|

When y is replaced by Y + k, the graph of y = f(x) shifts k units down

⇒ y replaced by Y + 5 translates the graph of y = f(x) 5 units down

∴ Y = g(x) is represented by Y + 5 = |x+3|

⇒ Y = |x+3| - 5

or g(x) = |x+3| - 5

A card is randomly selected from a standard deck of 52 playing cards. What is the probability that it is a face card or a spade?

Answers

Answer:

8/13.

There's 12 face cards & 26 black cards. In the 26 black cards, theres 6 face cards. Theres 32 cards overall that is either a black card or a face card. So in conclusion the answer is 8/13 because 52 (the total amt in the deck) divided by 32 = 8/13.

The probability of randomly selecting either a face card or a spade from a standard deck of 52 playing cards is approximately 0.4231.

The question involves calculating the probability of selecting either a face card or a spade from a standard deck of 52 playing cards. A standard deck consists of four suits (spades, hearts, diamonds, clubs), each with 13 cards, making a total of 52 cards. Among these, 12 are face cards (Jacks, Queens, Kings across all suits), and 13 are spades (including the spade face cards).

First, note that there are 3 face cards (Jack, Queen, King) in each suit, resulting in 12 face cards in total. However, 3 of these face cards are spades, and we must avoid double-counting them when adding the spade cards. Therefore, we have 12 face cards and 10 non-face card spades (since 3 spades are already counted among face cards), giving us a total of 22 unique cards that fulfill the conditions.

The probability of drawing either a spade or a face card from a deck of 52 cards is calculated by dividing the number of favorable outcomes (22) by the total number of outcomes (52), which is 22/52 or approximately 0.4231.

Answers

Answer:

The distance between the two buildings is 9.563 yards.

AB and CD are two buildings AC distance apart.

Now, AC = ED.

The angle of depression of clothesline BD is 17 Degrees.

Mitch paid $ 33600 altogether

Solution:

Given that mitch took out a school laon for $ 24000

The interest rate on the loan was 8%

Number of years = 5

To find: total amount paid altogether

We can use simple interest to calculate the total amount

Total amount paid altogether = simple interest + principal amount

The simple interest is calculated as:

[tex]\text { simple interest }=\frac{\text { principal } \times \text {rate of interest } \times \text {number of years}}{100}[/tex]

Plugging in values, we get

[tex]\text { simple interest }=\frac{24000 \times 8 \times 5}{100}=240 \times 8 \times 5=9600[/tex]

Total amount paid altogether = simple interest + principal amount

Total amount paid altogether = 9600 + 24000 = 33600

Thus Mitch paid $ 33600 altogether

1. What is the percent change from 1000 to 80?
2. What is the percent change from 45 to 63?
3. What is the percent change from 250 to 60?
4. What is the percent change from 60 to 99?

Answers

Step-by-step explanation:

1.-92%

2.40%

3.-76%

4.65%

The percent changes for each scenario is: 1. From 1000 to 80: -92% 2. From 45 to 63: +40% 3. From 250 to 60: -76% 4. From 60 to 99: +65%.

To calculate the percent change between two values, we use the formula:

[tex]\[ \text{Percent Change} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100\% \][/tex]

1. The percent change from 1000 to 80 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{80 - 1000}{1000} \right) \times 100\% = \left( \frac{-920}{1000} \right) \times 100\% = -92\% \][/tex]

So, the percent change is a 92% decrease.

2. The percent change from 45 to 63 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{63 - 45}{45} \right) \times 100\% = \left( \frac{18}{45} \right) \times 100\% = \frac{2}{5} \times 100\% = 40\% \][/tex]

So, the percent change is a 40% increase.

3. The percent change from 250 to 60 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{60 - 250}{250} \right) \times 100\% = \left( \frac{-190}{250} \right) \times 100\% = -76\% \][/tex]

So, the percent change is a 76% decrease.

4. The percent change from 60 to 99 is calculated as follows:

[tex]\[ \text{Percent Change} = \left( \frac{99 - 60}{60} \right) \times 100\% = \left( \frac{39}{60} \right) \times 100\% = \frac{13}{20} \times 100\% = 65\% \][/tex]

So, the percent change is a 65% increase.

Answer:

2462.4 square inches

Step-by-step explanation:

To find the length of the longer wall use the following ratio and solve for x.

x/36= 4.75/ 2.5

x= 68.4

Area of a rectangle = l(w)

68.4(36)= 2462.4 square inches

The area of the wall is the product of its dimension.

The area of the actual wall is  2462.4 square inches

The scale is given as:

Multiply both sides by 36

[tex]\mathbf{Long= 36 \times \frac{4.75 }{ 2.5}}[/tex]

[tex]\mathbf{Long= 68.4}[/tex]

So, we have:

[tex]\mathbf{Long= 68.4}[/tex]

[tex]\mathbf{Short= 36}[/tex]

The area is then calculated as:

[tex]\mathbf{Area = 68.4 \times 36}[/tex]

[tex]\mathbf{Area = 2462.4in^2}[/tex]

Hence, the area of the actual wall is  2462.4 square inches

In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.9 and f (C2) = 0.1. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0.a.Assuming the population begins in H?W equilibrium, what is C1 allele frequency after one generation of natural selection?b.Assuming the population begins in H?W equilibrium, what is C2 allele frequency after one generation of natural selection?c.Assuming random mating takes place among survivors, what is the genotype C1C1 frequency in the second generation?d.Assuming random mating takes place among survivors, what is the genotype C1C2 frequency in the second generation?e.Assuming random mating takes place among survivors, what is the genotype C2C2 frequency in the second generation?
