3 coins are tossed and two six-sided dice are rolled. how many possible outcomes are there?​

Hello!

Answer:

x = 7

Step-by-step explanation:

Substitute y = 4 into the equation and solve for x

8x - (2 × 4) = 48

8x - 8 = 48 ( add 8 to both sides )

8x = 56 ( divide both sides by 8 )

x = 7

The answer is:

The solution to the equation is:

[tex]x=6[/tex]

To solve the problem, we must remember how to operate with fractions.

So, adding fractions we have:

[tex]\frac{a}{b}+-\frac{c}{d}=\frac{(a*d)+-(b*c)}{b*d}[/tex]

Now, we are given the expression:

[tex]\frac{3}{x} +\frac{1}{3}=\frac{5}{6}[/tex]

So, solving we have:

[tex]\frac{3}{x} +\frac{1}{3}=\frac{5}{6}\\\\\frac{3}{x}=\frac{5}{6}-\frac{1}{3}\\\\\frac{3}{x}=\frac{(5*3)-(6*1)}{6*3}\\\\\frac{3}{x}=\frac{15-6}{18}\\\\\frac{3}{x}=\frac{9}{18}\\\\\frac{3}{x}=\frac{1}{2} \\\\3*2=1*x\\\\x=6[/tex]

We have that the solution to the equation is:

[tex]x=6[/tex]

For this case we have by definition, that the volume of a square base pyramid is given by:

[tex]V = \frac {1} {3} * L ^ 2 * h[/tex]

Where:

L: It's the side of the base (square side)

h: It's the height of the pyramid

Substituting:

[tex]L = 6 \ ft\\h = 10 \ ft[/tex]

[tex]V = \frac {1} {3} * (6) ^ 2 * 10\\V = \frac {1} {3} * 36 * 10\\V = 120 \ ft ^ 3[/tex]

Answer:

[tex]V = 120 \ ft ^ 3[/tex]

Answer:

two distinct real roots

Step-by-step explanation:

The coefficients of the equation are ...

a = 1

b = -5

c = -3

So, the discriminant, b^2-4ac, has the value ...

(-5)^2 -4(1)(-3) = 25 +12 = 37

This number is positive, so the square root of it is non-zero and real. This means the two roots are real and distinct.

Answer:

B) x + 1/y times h/g+1

Step-by-step explanation:

We need to divide [tex]\frac{x+1}{y}[/tex] by [tex]\frac{g+1}{h}[/tex] then match with given choices to find the correct equivalent result.

where given choices are:

A) x/y times h/g

B) x + 1/y times h/g+1

C) x+ 1/y divided h/g+1

D) y/x+1 divided g+1/h

So let's divide  [tex]\frac{x+1}{y}[/tex] by [tex]\frac{g+1}{h}[/tex]

[tex]\frac{\left(\frac{x+1}{y}\right)}{\left(\frac{g+1}{h}\right)}[/tex]

we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:

[tex]=\left(\frac{x+1}{y}\right)\cdot\left(\frac{h}{g+1}\right)[/tex]

Hence correct choice is: B) x + 1/y times h/g+1

Let's start by simplifying the given expression step-by-step:
\[ \text{Given Expression:} \quad \frac{x + \frac{1}{y}}{g + \frac{1}{h}} \]
Firstly, we will find a common denominator for the numerator and denominator of the given fraction.
For the numerator, we already have a single term x and a fraction \( \frac{1}{y} \), which can be combined without altering the denominator.
For the denominator, we have term g and a fraction \( \frac{1}{h} \). To combine these, we need to multiply both terms by h to get a common denominator.
So, the expression becomes:
\[ \frac{x + \frac{1}{y}}{g + \frac{1}{h}} = \frac{xy + 1}{y} \cdot \frac{h}{gh + 1} \]
Next, we will multiply the separated fractions across the numerator and the denominator:
\[ \frac{xy + 1}{y} \cdot \frac{h}{gh + 1} = \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \]
Now, let's consider the given options and check which one is equivalent to our simplified expression:
Option A) \( \frac{x}{y} \times \frac{h}{g} \)
This option simplifies to \( \frac{xh}{yg} \), which is not equivalent to the expression we have because we have \( xy + 1 \) in the numerator, not just \( xh \).
Option B) \( (x + \frac{1}{y}) \times \frac{h}{g+1} \)
For this option, if we simplify, we do not obtain a single fraction with the term \( xy + 1 \) in the numerator and \( y(gh + 1) \) in the denominator, instead, this option gives us \( xh + \frac{h}{y(g+1)} \), which is different from our simplified expression.
Option C) \( \frac{x + \frac{1}{y}}{h/(g + 1)} \)
To simplify this option, we take the reciprocal of the denominator and multiply it with the numerator:
\[ \frac{x + \frac{1}{y}}{h/(g + 1)} = (x + \frac{1}{y}) \times \frac{g + 1}{h} \]
\[ = \frac{(x + \frac{1}{y})(g + 1)}{h} \]
\[ = \frac{xg + x + \frac{g}{y} + \frac{1}{y}}{h} \]
\[ = \frac{xg + x + \frac{g + 1}{y}}{h} \]
This is not equivalent to our simplified expression either because it involves terms like \( xg \) and \( x \), which do not appear in our expression and does not fit the form \( \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \).
Option D) \( \frac{y/(x+1)}{g + \frac{1}{h}} \)
To simplify this option, we multiply by the reciprocal of the denominator:
\[ \frac{y/(x+1)}{g + \frac{1}{h}} = \frac{y}{x+1} \times \frac{h}{gh + 1} \]
\[ = \frac{yh}{(x+1)(gh + 1)} \]
Again, this is not equivalent to our simplified expression, since the expressions \( y/(x+1) \) and \( (xy + 1)/y \) are different.
None of the options (A, B, C, or D) match the simplified form:
\[ \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \]
Therefore, none of the given options are equivalent to the original expression \( \frac{x + \frac{1}{y}}{g + \frac{1}{h}} \).

Answer:

1. 1/4

2. 1/2

Step-by-step explanation:

If there are equal numbers of males and females, we can simplify that by saying there's one male and one female for each coat color.

1. What's the probability that both are males?

Well, there's a 1/2 chances the light-colored coat bear is a male and there's also a 1/2 chances the dark-colored coat bear is a male.  So, we can make this reference table:

Light             Dark

Male             Male

Male             Female

Female         Male

Female         Female

As you can see, the probability that both of the spotted bears are males is 1/4 (1/2 * 1/2).

2. If the light-colored bear, what are the odds both are males?

If we know for sure the light-one is male, then there's 1/2 chances the other is too, refer to the table above to verify.

Esther should save $125 each month to reach her goal of $3,000 in 2 years.

Esther wants to save $3,000 in 2 years and is determining the fixed monthly amount she should contribute to her savings. To find the monthly savings amount, we must divide the total savings goal by the total number of months in 2 years.

Total amount to save: $3,000
Total number of months: 2 years x 12 months/year = 24 months

Fixed monthly saving amount = Total savings goal / Total number of months
Fixed monthly saving amount = $3,000 / 24
Fixed monthly saving amount = $125

Answer:

Mindy uses more white beads

Step-by-step explanation:

For Mindy:

red : white = 4 : 5 = 12 : 15

For Daisy:

red : white = 6 : 7 = 12 : 14

When both use 12 red beads, Mindy uses 15 white beads and Daisy uses 14 white beads.

Mindy uses more white beads when both use 12 red beads.

When they each use 12 red beads, Mindy uses more white beads in her necklaces as per the given ratios. Mindy uses 15 white beads, while Daisy uses 14 white beads.

Mindy uses a ratio of 4 red beads to 5 white beads, and Daisy uses a ratio of 6 red beads to 7 white beads. If they each use 12 red beads, we can equate their ratios. For Mindy, the equivalent ratio would be 12 red beads to 15 white beads because 4 red beads go into 12 red beads three times and three times 5 gives 15 white beads. For Daisy, the equivalent ratio would be 12 red beads to 14 white beads as 6 red beads go into 12 red beads twice and twice 7 gives 14. Therefore, when they each use 12 red beads, Mindy uses more white beads in her necklaces using beads.

Answer:

Final answer is 1/8.

Step-by-step explanation:

Total number cards in deck of cards = 52

Total number of cards with a letter = 16

Total number of cards with red King and letter both = 2

Then probability of getting card with letter P(L) = 16/52

Then probability of getting card with letter and king both  P(K and L) = 2/52

Then required compound probability P(K|L) is given by formula:

P(K and L)= P(L)*P(K|L)

2/52= 16/52*P(K|L)

(2/52)*(52/16)=P(K|L)

2/16=P(K|L)

1/8=P(K|L)

Hence final answer is 1/8.

Answer:

The measure of the central angle is 35° to the nearest degree

The area of the triangle formed is 28.7 inches²

Step-by-step explanation:

* Lets revise the cosine rule to solve the question

- In Δ ABC:

# AB² = BC² + AC² - 2(BC)(AC) cos∠C

- If you want to find m∠C, we can rearrange the rule

# cos∠C = BC² + AC² - AB²/2(BC)(AC)

* Now lets solve the problem

- The length of the radius of the circle is 10 inches

- The length of the chord is 6 inches

- The chord and the two radii drawn to the endpoints of the chord

 formed an isosceles triangle and the angle between the two radii

 is the central angle

- Lets use the cosine rule to find the measure of the central angle

- Let the name of the central angle is Ф

∵ cos Ф = r² + r² - (chord)²/2(r)(r)

∵ r = 10 inches and the chord = 6 inches

∴ cos Ф = (10)² + (10)² - (6)²/2(10)(10)

∴ cos Ф = (100+ 100 - 36)/200

∴ cos Ф = 164/200 = 41/50

- Find the measure of the Ф by using cos^-1 Ф

∴ m∠Ф = cos^-1 (41/50) ≅ 35°

* The measure of the central angle is 35° to the nearest degree

- To find the area of the triangle we will use the sine rule

# Area of any triangle by using the sine rule is

  A = 1/2 × (s1 × s2) × sin the included angle between them

∵ s1 = r , s2 = r and the angle between them is the central angle Ф

∴ Area of the triangle = 1/2 (r × r) × sin Ф

∵ r = 10 and Ф = 35°

∴ Area of the triangle = 1/2 × (10 × 10) × sin 35°

∴ Area of the triangle = 50(sin 35°) ≅ 28.7 inches²

* The area of the triangle formed is 28.7 inches²

[tex]4^2+6=2x-6+6[/tex]

[tex]22=2x[/tex]

It's a system of linear equations; let me write it out more neatly for you:

[tex]\left \{ {x + 2y = 7} \atop {x - 2y = -1}} \right.[/tex]  

Good. In order to solve a system of equations with two variables, we can find one variable and then use that variable to find the other. This wouldn't be the case if we just had one equation, note.  

Let's work on the top one first. There's multiple ways of solving this one, but here's the most simple way: isolating a single variable. The goal is to get either just x or just y on one side.  

[tex]x + 2y=7\\x = 7-2y[/tex]  

Nice. Now that we have a value of x, we can just plug it into the other equation -- since we know that x is equal to another expression, we can replace x in the other equation with the expression.  

[tex]x - 2y = -1\\(7-2y)-2y = -1\\7 - 2y - 2y = -1\\7 - 4y = -1 \\-4y = -8\\y = 2[/tex]  

Now that we have y, we can do the same thing for x. This time, however, we have the actual value of y, meaning we can just plug that in.  

[tex]x = 7 - 2y\\x = 7 - 2(2)\\x = 7 - 4 \\x = 3[/tex]  

Our solution is  

[tex]\left \{ {{x=3} \atop {y=2}} \right.[/tex]  

We can check this by plugging the values back into the equation.  

[tex]3 + 2(2) = 7\\3 + 4 = 7[/tex]  

and  

[tex]3 - 2(2) = -1\\3 - 4 = -1\\[/tex]  

That's it. There's another (easier) way to handle this specific equation, but this is the simplest way to do it.

Answer:

Step-by-step explanation:

ΔNPM and ΔABM are similar (AAA). Therefore the corresponding sides are in proportion:

[tex]\dfrac{NM}{AM}=\dfrac{PM}{BM}[/tex]

We have

[tex]NM=67.2m,\ AM=67.2m-32m=35.2m,\ PM=81.9m,\ BM=x[/tex]

Substitute:

[tex]\dfrac{67.2}{35.2}=\dfrac{81.9}{x}[/tex]          cross multiply

[tex]67.2x=(35.2)(81.9)[\tex]

[tex]67.2x=2882.88[/tex]              divide both sides by 67.2

[tex]x=42.9\ m[/tex]

1. The area of a circle is calculated using the formula:

[tex]Area = \frac{\pi \: {d}^{2} }{4} [/tex]

The diameter is d=11 feet.

This implies that,

[tex]Area = \frac{\pi \times {11}^{2} }{4} [/tex]

[tex]Area = \frac{121\pi}{4} = 95.03 {ft}^{2} [/tex]

2. For this second question the diameter is d=10.5 feet.

We substitute into the formula to get;

[tex]Area = \frac{\pi \times {10.5}^{2} }{4} [/tex]

[tex]Area = \frac{441\pi }{16} = 86.60 {in}^{2} [/tex]

3. The area of a circle is given by the formula,

[tex]Area =\pi \: {r}^{2} [/tex]

where the radius is r=6.3

This implies that,

[tex]Area =\pi \: {(6.3)}^{2} [/tex]

[tex]Area =36.69\pi = 124.69 {cm}^{2} [/tex]

4. The given circle has a radius of 3.25 yards.

[tex]Area =\pi \times {3.25}^{2} [/tex]

[tex]Area =10.5625 \pi = 33.18 {yd}^{2} [/tex]
