Answer:

<DAB= 98

Step-by-step explanation:

Remark

I think you are supposed to assume that this is a parallelogram. In that case the two labeled angles are intended to be equal (one of the properties of a parallelogram).

Equation

2x + 36 = 3x - 5                    Add 5 to both sides

2x + 36 + 5 = 3x  - 5 + 5      Combine

2x + 41 = 3x                          Subtract 2x from both sides

2x - 2x + 41 = 3x - 2x           Combine

41 = x

Answer

<DAB = 2x + 36

<DAB = 2*41 + 36

<DAB = 82 + 36

<DAB = 98

is y=5/3x+3,20x+12y=12 a parallel, perpendicular.or a neither pair equation

Answers

Answer:

Neither

Step-by-step explanation:

y = 5/3 x + 3, this line has slope = 5/3

20x + 12y = 12

12y = -20x + 12

y = -20/12 x + 1

y = - 5/3 x + 1, this line has slope = - 5/3

Parralel ; same slopes

Perpendicular; slopes are opposite and reciprocal

So answer is neither pair parallel nor perpendicular

The pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel because they both have the same slope of 5/3 once the second equation is put into slope-intercept form.

To determine if the pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel, perpendicular, or neither, we must first put both equations into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. The equation y = 5/3x + 3 is already in slope-intercept form with a slope of 5/3. To convert the second equation into slope-intercept form, we can rewrite it as 12y = -20x + 12, and then y = (-20/12)x + 1, which simplifies to y = -5/3x + 1.

Now, comparing the slopes of these two lines, we see that both slopes are equal, meaning the lines are parallel to each other since they have the same slope but different y-intercepts.

A department store sells a pair of shoes with an 80% markup. If she store bought the pair of shoes for 55.25$, what is the selling price to the nearest dollar?

Answers

The selling price would be 99 dollars (rounded to the nearest dollar. It would be $99.45 if it is not rounded).

Explanation:

1. 55.25 is the original price in the problem, meaning it is 100%
2. If we need to find 80% of 55.25, we should set up a ration table.
3. 55.25 x
---------- = -------
100 80
4. From here, we need to cross multiply.
-55.25 times 80 is 4,420
-4,420 divided by 100 is 44.2
5. Since 44.20 is 80% of 55.25, we need to add the two prices together, because the store she bought them from marked them up (raised the price)
6. 44.20+55.25=99.45
7. Now, we round to the nearest dollar, which would be 99

Bhavik bought 33 liters of milk and 55 loaves of bread for a total of \$11$11. A month later, he bought 44 liters of milk and 44 loaves of bread at the same prices, for a total of \$10$10. How much does a liter of milk cost, and how much does a loaf of bread cost?

Answers

Answer: The cost of 1 liter milk is $ 0.75  and the cost of a loaf of bread is $1.75

Step-by-step explanation:

Let the cost of one liter of milk  is m dollar and the cost of one loaf of bread is b dollar.

Since, the total cost of the 3 liter milk and 5 loaf of bread = $ 11

That is, 3 m + 5 b = 11   ----------(1)

And, the cost of the 4 liter of milk and 4 loaf of bread = $ 10

That is, 4 m + 4 b = 10 -----------(2)

4 × Equation (1),

12 m + 20 b = 44 -----------(3)

3 × Equation (2),

12 m + 12 b = 30 --------------(4)

Equation (3) - Equation (4),

We get, 8 b = 14

⇒ b = 14/8 = 1.75

 By putting the value of b in equation (1)

We get,

3 m = 11 - 1.75×5 ⇒ m = 2.25/3 = 0.75

Thus, the price of one liter of milk = $ 0.75

And, the price of one loaf = $ 1.75

Answer:

The cost of 1 liter milk is $ 0.75  and the cost of a loaf of bread is $1.75

Suki rode her bike 4/5 mile. Claire rode her bike 1/3 mile. they want to compare how far they each rode their bikes using the Benchmark 1/2

Answers

Suki rode her bike a longer distance than Claire because when comparing each of their distances to the benchmark of 1/2 mile, Suki's distance (4/5 mile) is greater than the benchmark (1/2 mile), while Claire's distance (1/3 mile) is less than the benchmark. Therefore, Suki rode a longer distance than Claire in relation to the benchmark.

Suki's Distance with Benchmark (1/2):

Suki rode her bike for 4/5 miles.

The benchmark is 1/2 mile.

Comparison: [tex]\frac{4}{5} > \frac{1}{2}[/tex]

Interpretation: Suki's distance ( 4/5 miles) is greater than the benchmark 1/2 mile.

Claire's Distance with Benchmark (1/2):

Claire rode her bike for 1/3 mile.

The benchmark is 1/2 mile.

Comparison: [tex]\frac{1}{3} < \frac{1}{2}[/tex]

Interpretation: Claire's distance ( 1/3 mile) is less than the benchmark 1/2 mile.

Overall Comparison:

Suki's distance (4/5) is greater than Claire's distance (1/3).

Interpretation: Suki rode her bike a longer distance than Claire.

In summary, both Suki and Claire are comparing their distances to the benchmark of 1/2 mile. Suki's distance is greater than the benchmark, while Claire's distance is less than the benchmark. Therefore, Suki rode a longer distance than Claire.

simplify
a/5x−10 + a/6x−12

Answers

I think the answer is 22
Final answer:

To simplify the expression, find the common denominator, distribute the 'a' to each term, and combine like terms.

Explanation:

To simplify the expression  a/5x-10 + a/6x-12, we need to find a common denominator for the two terms. The common denominator is 30x(x-2). We then multiply each term by the appropriate factor to get a common denominator. This simplifies the expression to:

a(6x-12) + a(5x-10) / 30x(x-2)

Now, we can distribute the 'a' to each term:

6ax - 12a + 5ax - 10a / 30x(x-2)

Combining like terms, we get a(11x - 22) / 30x(x-2).

If f(x)=x+7 and g(x)=1/x-13, What is the domain of (f•g)(x)

Answers

Answer:

F(x) = x+7

g(x) = 1/(x-13)

fog(x) = [1/(x-13)] + 7

The denominator of the fraction cannot be equal to zero.

So, the domain of fog(x) is x∈R~{13}

Step-by-step explanation:


Final answer:

To find the domain of (f•g)(x), substitute g(x) into f(x) and identify any values of x that make the expression undefined.

Explanation:

The function (f•g)(x) represents the composition of two functions, f(x) and g(x). To find the domain of (f•g)(x), we need to determine the values of x for which the composition is defined.

The composition (f•g)(x) can be written as f(g(x)). Substituting g(x)=1/x-13 into f(x)=x+7, we have f(g(x))=(1/x-13)+7.

The domain of (f•g)(x) consists of all the values of x for which the expression (1/x-13)+7 is defined. Since division by zero is not defined, we need to exclude x=0 from the domain. Additionally, we need to exclude the value x=13 because the expression (1/x-13)+7 would lead to division by zero. Therefore, the domain of (f•g)(x) is x≠0, 13.

female comedy: 36 female drama: 24

Step-by-step explanation:

add f+m=100 total

31 males for comedy

40 males - 31 males = 9 males for drama

55% chose comedy so 55-31 males = 24 females for comedy

60 total females - 24 for comedy = 36 females for drama

Answer:

                         Dramas              Comedies

Males                   9                             31

Females             36                            24

Step-by-step explanation:

It is given that Lamar surveyed 40 males and 60 females about whether they prefer dramas or comedies.

Total males = 40

Total females = 60

Total people surveyed = 40 + 60 = 100

It is given that 55% of surveyed people preferred comedies.

People preferred comedies = [tex]100\times \frac{55}{100}=55[/tex]

It is given that males who preferred comedies = 31

Males who preferred drama is the difference of number of males and males who preferred comedies.

Males, drama = 40 - 31 = 9

Females who preferred comedies is the difference of people who preferred comedies and males who preferred comedies.

Females, comedies = 55 - 31 = 24

Females who preferred drama is the difference of number of females and females who preferred comedies.

Females, drama = 60 - 24 = 36

Therefore the table can be filled as

                         Dramas              Comedies

Two parallel lines are crossed by a transversal . What is the value of k?

Answers

Answer:

k = 60

Step-by-step explanation:

2k + 11 is a same side corresponding angle, hence

2k + 11 = 131 ( vertically opposite angles )

subtract 11 from both sides

2k = 120 ( divide both sides by 2 )

k = 60


Answer:

Option C. k = 60

Step-by-step explanation:

There are two lines Z and Y and crossed by a transverse x.

We have to find the value of k.

Since opposite angle of ( 2k + 11 ) is corresponding angle of 131°

so opposite angle of ( 2k + 11 ) will be = (2k + 11)

and corresponding angles are equal in measure.

So 2k + 11 = 131

    2k = 131 - 11

   2k = 120

    k = 60

Option C k = 60 is the answer.

Answer:

The two equal (same length) sides are 10.68 metres each.

Step-by-step explanation:

45.56 - 24.2 = 21.36 m (length of the 2 equal sides)

21.36 ÷ 2 = 10.68 metres

Answer:

10.68 m

Step-by-step explanation:

We are given that a perimeter of 5-sided figure =45.56 m

Two side of same length

Sum of three sides of given figure=24.2 m

We have to find the length of each side of the same length and explain.

Let x be the length of each side of same length

We know that

Perimeter of 5- sided figure=Sum of  length of  five sides

Therefore,

x+x+24.2=45.56
