95 = b^2

sqrt(95) = b

The probability of rolling a number greater than 4 on a number cube is 1/3 or 0.33.

A number cube is a cube-shaped object with six sides, numbered from 1 to 6. When rolling the number cube, there are six possible outcomes, each with an equal chance of occurring. Since we are interested in finding the probability of rolling a number greater than 4, we need to determine how many of the six possible outcomes meet this condition.

There are two possible outcomes that satisfy the condition: rolling a 5 or rolling a 6.

So, as there are two outcomes = 2/6

= 1/3

Therefore, the probability of rolling a number greater than 4 is 1/3.

This can also be simplified to 0.33 or 33.3% as a decimal or percentage, respectively.

The values of the trigonometric identities are;

1. tan X = 10/17

2.  tan X = 29/25

3. sin A = 24/25

4. tan C = 15/17

5. sin A = 8/17

6. cos A = 9/41

7. cos Z = 3/4

Note that fractions are the part of a whole number.

Also,

sin θ = opposite/hypotenuse

cosθ = adjacent /hypotenuse

tan θ = opposite/adjacent

1. tan X = opposite/ adjacent

tan X = 30/21 = 10/7

2. tan X = 29/25

3. sin A = opposite/hypotenuse

sin A = 24/25

4. tan C = opposite/adjacent

tan C = 30/34

tan C = 15/17

5. sin A = 16/34

sin A = 8/17

6. cos A = adjacent/hypotenuse

cos A = 9/41

7. sin A = 21/35

8. cos Z = 21/28

cos Z = 3/4

Hence, the fractions takes the function of the trigonometric identities.

Answer:

$3

Step-by-step explanation:

3 dollars because

1 pound = 16 ounces

and 1 pound costs 1.5 dollars

if there are 32 ounces of broccoli, you divide the number of ounces by 16 and multiply that by 1.5

32/16 = 2 x 1.5 = 3

Answer:

$3.00

Step-by-step explanation:

Since 1 pound = 16 ounces and there are 32 ounces, by dividing 32/16 will equal to 2 pounds, hence $1.50 x 2 =$ 3.00

Step-by-step explanation:

Appling percentages, if Ms. Lama marked the price of a a cosmetic items 25% above it's cost price and the cost price of the cosmetic items was Rs.4400 sold with 13% VAT, the selling price is $6,215.

The selling price is determined by increasing the cost price by the markup percentage and then the VAT percentage.

Cost price of the cosmetic items = Rs.4,400

Markup = 25%

Markup factor = 1.25 (1 + 0.25)

Marked up price = Rs.5,500 (Rs.4,400 x 1.25)

VAT = 13%

Markup ith VAT factor = 1.13 (1 + 0.13)

Selling price = Rs.6,215 (Rs.5,500 x 1.13)

Thus, Ms. Lama sold the cosmetic items at Rs.6,215, 13% VAT inclusive.

Answer:

a

Step-by-step explanation:

- 6x + 2y = - 12 → (1)

6x + 5y = 117 → (2)

Add the 2 equations term by term to eliminate the x- term

0 + 7y = 105

7y = 105 ( divide both sides by 7 )

y = 15

Substitute y = 15 into either of the 2 equations and solve for x

Substituting into (2)

6x + 5(15) = 117

6x + 75 = 117 ( subtract 75 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

solution is (7, 15 ) → a

Answer:

363 feet = 11 seconds

Step-by-step explanation:

330 feet = 10 seconds

=> 330/10 feet = 10/10 seconds

=> 33 feet = 1 second

=> 33 × 11 feet = 11 × 1 second

=> 363 feet = 11 seconds.

Therefore, the Burj Khalifa can travel 363 feet in 11 seconds.

Answer:

\(363ft\)

Step-by-step explanation:

First we know that the elevator can travel 330 feet  in just 10 seconds. That's can be interpret as:

\(\frac{330ft}{10s} = \frac{33ft}{1s}\)

How you can see each second the elevator travel 33 feet so if you want to know how many travel in 11 second you only have to multiply by 11 the 33ft.

\(33ft \cdot 11s = 363ft\)

Answer:

(2,10) or x=2 y=10

Step-by-step explanation:

1. Pick one of your equations and solve for a variable. I chose the first equation and solved for x.

5x-2y=-10 (Move the -2y to the other side, you need to do the opposite so you add +2y to -10)

5x=2y-10 (Divide the 5 from the x)

x=2/5y-2

2. Now take what you got for x and plug it into the x variable on the other equation.

3(2/5y-2)+6y=66 (Multiply 3 by 2/5y and -2)

6/5y-6=6y=66 (Move the -6 to the other side and add 6/5y to 6y)

36/5y=72 (Since the number on the y is a fraction, you must do the opposite to the other side)

y=72/1 x 5/36 (Flip your fraction and multiply it by the 72)

y=10

3. Now that you have one of the variables solved for, in order to get the other we must plug in what we have to the first equation.

5x-2(10)=-10 (Multiple 2 by 10)

5x-20=-10 (Move -20 to the other side, since you do the opposite add +20 to the -10)

5x=10 ( Divide 10 by 5)

x= 2

4. If needed, plug in the values of x and y to check your solution.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

For question number 8 all you have to do is add all the sides and make them equal to 180 so when you make it into an equation it'll look like this...

\(10x-11+3x+1+3x-2=180\)

Now you combine like terms then solve...

\(10x-11+3x+1+3x-2=180\\16x-12=180\\16x=192\\x=12\)

So now you got x = 12.

___________________________________________________________

For question number 10 you should now that those two angles inside add up to the angle on the outside so if you know that those two angles add up to the outer angle, you should make an equation like this...

\(11x-1+20x-3=151\)

Now combine like terms and solve...

\(11x-1+20x-3=151\\31x-4=151\\31x=155\\x=5\)

So now you have x = 5.

The ratio of the height of the building to the number of floors is 15:1.

A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

A unit rate is a price for one unit of anything. This is written as a ratio with a denominator of one. The denominator of a unit rate is always 1.

The unit rate is the denominator of a ratio of two different units. For instance, kilometer/hour, meter/sec, mile/hour, salary/month, and so on.

The following can be deduced based on the information:

Number of floor = 9

Height of the building = 135

The ratio of the height to the floors will be:

= 135 : 9

This will be reduced to the lowest term and will give 15:1.

System of equation : 14x+23y = 213 and y = x-2

The cost of regular tickets is $7 and the cost of tickets with donation is $5.

Step-by-step explanation:

Let regular ticket's cost be x and tickets with donation's cost be y.

14x+23y = 213

y = x-2

Now,

14x+23y = 213

or, 14x+23(x-2) = 213

or, 14x + 23x - 46 = 213

or, 37x = 259

so, x = 7

again,

y = x-2

or, y = 7-2

so, y = 5
