Answer:

the answer is 192 , hope it helps

Step-by-step explanation:

so,

1/12 × $100

5/12 × $20

6/12 × $1

so the expected "payout" is

100/12 + 100/12 + 6/12 = 206/12 = 103/6 ≈ $17.17

minus the $2 entrance fee, the expected value is

17.17 - 2 = $15.17

but of course, there will be 6 losing $1 (while the other 6 will go home with a positive result).

Answer:

4 kg

Step-by-step explanation:

Since the mass of one small brick is 1.5 kg, the mass of 8 small bricks is 1.5 × 8, or 12 kg. Since 12 kg is the total mass of 3 large bricks, it follows that each large brick will have a mass of 12 ÷ 3, or 4 kg.

Inequalities help us to compare two unequal expressions. The correct option is D.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given expression can be solved as,

[tex]\dfrac{\sqrt{7x^2}}{\sqrt{3x}}\\\\= \dfrac{\sqrt{7}x}{\sqrt{3x}}\\\\= \sqrt{\dfrac{7x}{3}}[/tex]

Since the value of (7x/3) is needed to be positive, therefore, the inequality that represents all the values of x for the quotient is defined as x>1.

Hence, the correct option is D.

Answer: x>0

Step-by-step explanation:

Using translation concepts, it is found that the equation represented on the graph is of:

d. [tex]y = \sin{(x - \pi)}[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, we have a trigonometric function, with amplitude of 1, hence there was no vertical translation, which removes options a and b.

The function is of zero at the origin, 1 at [tex]\frac{\pi}{2}[/tex] and -1 at [tex]\frac{\pi}{2}[/tex]. The sine function is of 0 at [tex]-\pi[/tex], of -1 at [tex]-\frac{\pi}{2}[/tex] and of 1 at [tex]-\frac{3\pi}{2}[/tex], hence option d is correct.

The period is the distance between two peaks

Answer:

$420

Step-by-step explanation:

number of people = 5 (4 friends + serena)

number of cars = 2

cost of parking = 7 for each car = 7 * number of cars = 7 * 2 = 14

let t be the cost of each ticket

cost of tickets = t for each person = t * 5

total cost = cost of parking + cost of tickets

= 14 + t * 5

= 2114

2114 = 14 + 5t

subtract 14 from both sides to isolate the variable and its coefficient

2100 = 5t

divide both sides by 5 to isolate t

t = 2100/5 = 420

Hello!

The formula for the area of a circle is [tex]A = \pi r^2[/tex]

The radius is half of the diameter, given with the formula [tex]D = 2r[/tex]

Using the information, we can first solve for the radius.

The radius is 9

Now we can plug 9 into the area formula:

We are going to use 3.14 for pi

The area is 254.34cm².

We are going to round to the nearest whole centimeter, which is roughly 254cm² or [tex]\boxed{\text{Option B}}}[/tex]

What's the question?

Answer:

62.7

Step-by-step explanation:

Cos(ang) = Adjacent / hypotenuse

cos(37) = 48/x

x = 48 / cos(37)

x = 62.71

Answer:

x = 60.1

Step-by-step explanation:

- The provided side length is adjacent to given degree

- and we are lookin for the hypotenuse  

SOH CAH TOA stands for,

sinx = opposite / hypotenuse

cosx = adjacent / hypotenuse

tanx = opposite / adjacent

cosine fulfills everything we have provided so we will choose cos

NOTE: x in cosx represent the degree amount

Solving:

cosx = adjacent / hypotenuse

cos(37°) = 48 / x

multiply both sides by x,

cos(37°)x = 48

divided both sides by cos(37°) to get x alone

x = 48 / cos(37°)x

x = 60.1025

18 × 3 = 54

then the next denominator is

54 × 3 = 162

Answer:

162

Step-by-step explanation:

The multiplication number will be 3.

2x3=6

6x3=18

18x3=54

54x3=162. and so on.

Answer:

22.5

Step-by-step explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 11 women, with the mean being 19, we can see that the ages summed to 209:

11 x 19 = 209

And then we can do the same for men:

11 x 26 = 286

And now we can combine the sum and count of the men and women to find the mean for the office:

286 + 209 = 495

495/22 = 22.5

Step-by-step explanation:

How to Convert a Percent to a Decimal

Here are two ways to convert a percent to a decimal,

1. Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.

Example: 62.5% becomes 62.5/100 = 0.625

2. This way is easier and faster. Start by removing the percent sign and moving the decimal point 2 places to the left.

Example: 62.5%

⇒ 62.5

⇒ 6.25

⇒ .625

Hence, the answer is 0.625.

Step-by-step explanation:

in a parallelogram]

• opposite sides are congruent

• opposite angles are congruent

• consecutive angles are supplementary , sum to 180°

• diagonals bisect each other

Then

DC = AB = 15

BC = 2 × WC = 2 × 9 = 18

∠ BAC = ∠ BDC = 110°

∠ DCA = 180° - 110° = 70°

DC = 15 (opposite sides in a parallelogram is parallel and equal to each other)
BC = 18 (the diagonals in a parallogram bisect at their midpoints -> BW = WC = 9 -> BC = 9 + 9 = 18)
angle BAC = 110 (opposite angles are equal to each other)
angle DCA = 70 (consecutive angles add up to 180, angle BAC and angle DCA are consecutive -> 180 - 110 = 70)
