Answer:

AC = 12

Step-by-step explanation:

If BC is parallel to DE then ∠D ≅ ∠B and ∠E ≅ ∠C. Therefore

ΔABC is similar to ΔADE.

The sides of smaller triangle are in proportion with sides of bigger triangle.

Therefore we have the equation:

AC/AE = AB/AD

Substitute the given numbers:

x/x+15 =8/18

18x= 8(x+15)

18x = 8x+120

10x = 120

x = 12

AC=12

Solution:

15 outfits

Step-by-step explanation:

i think the answer is this because:

5 pants x 3 pairs of blue and red socks equals to 5x3 = 15...

example of same question but different number of pairs of socks:

I have five pants with different colours and two pairs of pink socks and two pairs of yellow socks. how many ways can i dress if I want to wear socks with different colours?

solution:

5x4 = 20. so, 20 outfits

Answer:

  10

Step-by-step explanation:

We assume "I want to wear socks with different colors" means you want a red sock on one foot and a blue sock on the other foot. There are two ways to do that: RB or BR.

For each of those two ways to wear the socks, you can choose any of 5 pairs of pants. You can dress 2×5 = 10 different ways.

Answer:

$362.70

Step-by-step explanation:

21 + 39 = 60 minutes ( 1 hour)

So for the remaining time she lifted weights for about 2 hours.

3 hours = 180 minutes

180 - 60 = 120

About 66% of the remaining time Yael used to lift weights.

To be accurate 66.6% ( the last 6 repeating a infinite amount of time aka it doesnt end)

Answer:

x=6

Step-by-step explanation:

7+5(×-3)=22

expand the brackets:

7 + 5x - 15 = 22

simplify:

5x - 8 = 22

add 8 to both sides:

5x = 30

divide both sides by 5

x = 6

hope this helps

brainliest plz?

x

Answer:

7+5 (x-3)=22

7+5x-15=22

5x+ -8=22

5x=30

x=6

Step-by-step explanation:

PEMDAS

First distribute in the parentheses

Then add like terms together

once you have -8, add it on both sides

then divide 5 from both sides to leave the unknown variable by itself

Finally you have the answer

The answer is A.

An indefinite integral is a function that, when differentiated, equals the original function. It is denoted by ∫f(x)dx, where f(x) is the function to be integrated. An indefinite integral always has an arbitrary constant of integration, which is denoted by C. This is because the derivative of any constant is zero, so the derivative of ∫f(x)dx+C is still equal to f(x).

A definite integral is the limit of a Riemann sum as the number of terms tends to infinity. It is denoted by ∫

a

b

​

f(x)dx, where a and b are the limits of integration. A definite integral does not have an arbitrary constant of integration, because the limits of integration specify a unique value for the integral.

In other words, an indefinite integral is a family of functions that share the same derivative, while a definite integral is a single number.

Answer:

b)

Step-by-step explanation:

a) y = 4x +1 y= -4x + 1

Different slopes; same y-intercept; lines intersect at 1 point; there is 1 solution.

b) y= 2x + 7 y= 2x - 7

Same slopes; different y-intercepts; parallel lines do not intersect; no solution.

c) 3x + y =1 6x + 2y =2

Equations are the same; infinite number of solutions.

d) 5x + y =3 x + 5y = 15

Different slopes; lines intersect at 1 point; there is 1 solution.

\( \sf \longrightarrow \: 5 \bigg( \: n - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{n}{1} - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10 \times n - 1 \times 1}{1 \times 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10n - 1}{ 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: \: \frac{50n - 5}{ 10} = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: \: 2(50n - 5) =1(10) \\ \)

\( \sf \longrightarrow \: \: 2(50n - 5) =10 \\ \)

\( \sf \longrightarrow \: \: 100n - 10=10 \\ \)

\( \sf \longrightarrow \: \: 100n =10 + 10\\ \)

\( \sf \longrightarrow \: \: 100n =20\\ \)

\( \sf \longrightarrow \: \:n = \frac{2 \cancel{0}}{10 \cancel{0}} \\ \)

\( \sf \longrightarrow \: \:n = \frac{1}{5} \\ \)

Answer:-

To solve the equation \(\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\\) for \(\sf n \\\), we can follow these steps:

Step 1: Distribute the 5 on the left side:

\(\sf 5n - \frac{1}{2} = \frac{1}{2} \\\)

Step 2: Add \(\sf \frac{1}{2} \\\) to both sides of the equation:

\(\sf 5n = \frac{1}{2} + \frac{1}{2} \\\)

\(\sf 5n = 1 \\\)

Step 3: Divide both sides of the equation by 5 to isolate \(\sf n \\\):

\(\sf \frac{5n}{5} = \frac{1}{5} \\\)

\(\sf n = \frac{1}{5} \\\)

Therefore, the solution to the equation \(\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\\) is \(\sf n = \frac{1}{5} \\\), which corresponds to option (d).

Answer:

Step-by-step explanation:

Each hour, Jim does 1/3 of the job if working alone.

Each hour, John does 1/5 of the job if working alone.

Let x = number of hours to do the job if they work together.  So, each hour, they do 1/x of the job when they work together.

We get the equation:  1/3 + 1/5 = 1/x

Multiply the equation by the LCD, 15x:   5x + 3x = 15

                                                                             8x = 15

                                                                               x = 15/8 = 1 7/8 hrs

Step-by-step explanation:

this is because one quart is 4 cups and 4 quarts are one gallon. this means that if you use three quarts, you have one left over. one quart is the same as 4 cups

that "photo" is a danger to your device

One quart is the same as the 4 cups of milk she has leftover, the option C is the correct answer.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Sondra has 1 gallon of milk. Her pudding recipe calls for 1 quart of milk, but she triples the recipe.

1 gallon of milk = 1 quart of milk,

one quart is 4 cups and 4 quarts is one gallon which means that if you use three quarts, you have one leftover.

one quart is the same as 4 cups.

The average rate of change of the function over the interval is 4

From the question, we have the following parameters that can be used in our computation:

y = 4x + 1

The interval is given as

[-1, 1)

The function is a linear function

This means that it has a constant average rate of change

From y = 4x + 1, we have

Rate = 4

Hence, the rate is 4

The linear function y = 2x + 5 shows that Sarah charges $5 as fixed amount before she begins selling newspapers.

The table representing amount of money which Sarah charges her customers to sell newspapers.

Let us consider 'x' represents the time per hour charges taken by Sarah from customers.

In the table,

For zero hours charges are $5.

It means Fixed charges taken by Sarah to sell newspaper.

Difference between the rate per hour is,

$7 - $5 = $2

$9 - $7 = $2

It represents for Sarah charges $2 per hour.

let us consider 'y' that represents total amount charges by Sarah.

Required linear function for selling news paper and charging amount is

y = $5 + 2x

⇒ y = 2x  + 5

Therefore, the linear function y = 2x + 5 represents option 1. Sarah charges $5 before she begins selling newspapers.

Sets are defined as in mathematical and logical collection of elements or objects, numbers or functions.

The members of a set are listed in enclosed braces.

The elements and objects of a set are well-defined and fixed.

Given the sets as;

S= [E1, E2, E3, E4, E5, E6, E7, E8, E9, E10]

A = [E1, E3, E6, E9]

A is defined as a subset of the sample space, S

a. It is important to note that the intersection of two sets involves the elements or objects that are common between them.

Given that;

A = [E1, E3, E7, E9]

B = [E2. E3, E, E9]

A∩B = { E3, E9}

b. Note that the union of sets involves the collection of the elements of both sets without repetition.

A∪B = {E,  E1, E2, E3,E7, E9}

c. The union of the sets A and B are together exhaustive as it contains all the elements in both sets.
