Answer:

146

Step-by-step explanation:

becuase it's parallel, so x = 146

The number of cases they go through in (x > 18.75 ) 30 days is greater than 18.75.

In this problem, Renata and her family go through an average of more than 15 cans of sparkling water each day. This means that in 30 days, they will go through a total of more than 15 * 30 = 450 cans of sparkling water.

They buy the sparkling water in cases of 24 cans each, and each case costs $3.5. To calculate the number of cases they need to buy, we divide the total number of cans they need by the number of cans in each case.

450 cans ÷ 24 cans per case = 18.75 cases

Since they need to buy more than 18.75 cases, we use the inequality symbol ">" to express this as:

x > 18.75

where x represents the number of cases of sparkling water they go through in 30 days.

A true statement on the mean number of lessons for the dogs is The mean number of lessons for group A is greater than the mean for group B by 1 MAD.

The difference in the mean number of lessons between the two groups being Group A and Group B is :

= Mean number of lessons Group A - Mean number of lessons Group B

= 5 - 3

= 2

The mean absolute deviation for Group B is 2. The mean number of lessons of group A related to this is :

= 2 / 2

= 1

This shows that the mean number of lessons for group A is greater than the mean for group B by 1 MAD.

The supplied document states that Juan must pay $265.32 in total for the instrument.

Any transaction in which goods or services are exchanged for cash is referred to as a sale. In other words, a transaction is any activity that involves transferring ownership of a good or service to the buyer in exchange for cash.

The instrument costs $329.99 at standard pricing.

$329 * 25% = $82.50

The guitar's discount price is thus $329.99 less $82.50, or $247.49.

7.25% of the purchase price is used to compute sales tax.

Therefore, $247.49 * 7.25% = $17.83

As a result, we eventually tack on the taxation to the purchase price to determine Juan's final obligation to pay for the guitar.

$247.49 + $17.83 = $265.32

The total price that Juan shall pay for something like the guitar is thus $265.32.

The expression 32.6/10 - 5 x 8 - 9.16 + 88.9 has the value of 43.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Let's the expression to be found be "y".

An expression that, when evaluated, gives us a value of 43 is required.

Start by manipulating the given expression to isolate the value of "y".

Use the order of operations (PEMDAS) to simplify the expression -

32.6/10 - 5 × 8 - 9.16

3.26 - 40 - 9.16 (since 5 × 8 = 40)

-45.9

So the value of the given expression is -45.9.

To make the expression equal to 43, add a constant term to it -

y = 32.6/10 - 5 × 8 - 9.16 + 88.9

Evaluate this expression -

y = 3.26 - 40 - 9.16 + 88.9

= 43

Therefore, the expression obtained is 32.6/10 - 5 x 8 - 9.16 + 88.9.

The domain of the equation A = 25/ ( y - 9 ) is y < 9 or y > 9 and the interval notation is ( -∝ , 9 ) ∪ ( 9 , ∝ )

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 25/ ( y - 9 )   be equation (1)

when y = 0 , the equation is undefined

So , the domain of the function will be y < 9 or y > 9 and the interval notation is ( -∝ , 9 ) ∪ ( 9 , ∝ )

Answer:

138

Step-by-step explanation:

720 - all the angles added up gives you the missing angle

Answer:

x = 138°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 6 , then

sum = 180° × (6 - 2) = 180° × 4 = 720°

sum the interior angles and equate to 720°

x + 85° + 135° + 125° + 85° + 152° = 720°

x + 582° = 720° ( subtract 582° from both sides )

x = 138°

Ryan rides his bike for 30 minutes and travels a distance of 4 miles. He was traveling 8 miles per hours.

Ryan rides his bike for 30 minutes and travels a distance of 4 miles.

We have to determine how fast he was traveling.

Time = 30 minutes

First we convert the minutes in hours.

As we know that;

1 hour = 60 minutes.

So 1 minute = 1/60 hours

30 minutes = 30/60 hours

30 minutes = 1/2 hours

Distance = 4 miles

The formula of speed is;

Speed = Distance/Time

Speed = 4/(1/2) miles per hours

Speed = 4 × 2 miles per hours

Speed = 8 miles per hours

Let's call the number of first-class tickets Sarah purchased x. Then the number of coach tickets purchased is 9 - x.

The total cost of the first-class tickets was x * $980 and the total cost of the coach tickets was (9 - x) * $120.

The total budget for airfare was $6240, so we can set up the following equation:

x * $980 + (9 - x) * $120 = $6240

Solving for x, we get:

x = 5

So, Sarah purchased 5 first-class tickets and 9 - x = 4 coach tickets.

Answer:

Step-by-step explanation:

Perimeter of the rectangle= 42 cm

                               Length= x

                              Breadth= y

                                  2(x+y)= 42

                                     x+y= 42/2= 21 (Let it be the first equation)

Perimeter of the triangle= 36 cm

                         x+y+2y-3= 36 cm (Let it be the second equation)

Substitute equation 1 in 2.

 x+y+2y-3= 36

⇒ 21+2y-3= 36

            2y= 36-21+3

            2y= 18

              y= 18/2

              y= 9

x+y= 21

x+9= 21

   x= 21-9

   x= 12

∴ the values of x and y are 12 and 9 respectively.

After buying x bottles of water, the money will remain in her checking account is equals to the $(250 - 2x). So, the correct answer is option (b).

We have Denise has a checking account.

The amount on her checking account = $250

The price of each water bottle = $2

Number of boltes bought by Denise = x

Let the total remaining money after the spend by Denise on water bottles be " $y". Total cost of x bottles = number of bottles × cost of one bottle

= x× $2 = $ 2x

We have to determine the value of y. The money remaining in her account = total amount in her checking account - spends money

=> y = $ 250 - $2x

which is a two variable linear equation, when we know that how many bottles she buy, i.e., value of x then we will determine the value of y. So, the required value is $ 250 - $2x .

2(3w-6)

2 • (3w - 6)

2 • 3w - 2 • 6

6w - 12

The expression 2(3w-6) can be expanded by first multiplying the two together. This is done by multiplying the coefficient of 2 with each of the terms inside the parentheses. This results in 2 • 3w - 2 • 6. Next, the terms inside the parentheses can be combined. Since they are both being multiplied by 2, we can simply add the two terms together, resulting in 6w - 12.

The proportion of minor arc ZPSR is equivalent to 48 degrees.

Given a circle Q with focus Q and minor curve PR with a proportion of 48 degrees, the objective is to find the proportion of ZPSR, the focal point that compares to the minor circular segment PR.

Since the focal point and the circular segment length of a circle are corresponding, the proportion of ZPSR can be found by partitioning the proportion of the minor curve PR by 360 degrees and afterward duplicating by the all out number of degrees all around, which is 360.

The recipe for the focal point comparing to a minor circular segment is given by:

mZPSR = (mPR/360) × 360

Subbing the given worth of mPR = 48, we get:

mZPSR = (48/360) × 360

Answer:

Step-by-step explanation:

The answer is Graph B.

First the equation needs to be in standard form.

x² + 8x= -20

becomes    y = x² + 8x + 20

The leading coefficient is positive - a positve one is in front of the x.

So the parabola opens upward.

solve for the x coordinate of the minimun by using the formula

x = -b/2a

x = -8/2(1) =  - 8/2 =   -4

substitute -4 into the original equation.

y = (-4)² + 8(-4) + 20

y = 16 + -32 + 20

y = -16 + 20

y = 4

so the minimun - or bottom of the parabola is (-4, 4)

Correct choice is graph B
