Answer:

7.07cm

Step-by-step explanation:

A=πr2

= 100 π

= 314.159265359/2 (squared)

50% = 157.07963268cm ^2

We look for radius in the area formula

A=πr2

(A / π ) = 157.07963268/ 3.14159265359 =  √50 = 7.07106781187

We do not need to half this as already has been squared.

Answer:

Follow steps 1, 2 and 3.

Step-by-step explanation:

What we must do we will follow in the following steps:

1. Draw a line and make 5 vertical marks about 1/2 inch.

2. Label the middle one 0 and then label the right ones zero 1 and 1.5.

3. Perform the same procedure from step two on the left but negative.

Answer:

1 3 /4

is equal to 1.75. I would plot 1.5 and 1.75 between 1 and 2, but 1.75 would be closer to 2. Since 1.75 is further to the right, it is greater than 1.5.

Answer:

The value of x is 40.

Step-by-step explanation:

These are vertical angles meaning that these are both the same angle. We can express this into an equation. (3x - 6) = 114, usually with an equation like this we add the 6 from (3x - 6) and also add it to 114 because whatever you do to one side of the equation you have to do to the other. Because we added 6 to (3x - 6) the 6 from there is gone and since we added 6 to 114 it is now 120 so now the equation is 3x = 120. Now we divide each side me 3 to get the value of x. 3x divided by 3 is x. 120 divided by 3 is 40. So now our equation looks like this, x=40. So this is how the value of x is 40. Let me know if it's right!!

One candle:

½ × 10 × 7 × 6

= 210 cm³

42 candles:

42 × 210

= 8,820 cm³

Answer:

8820 cm^3

Step-by-step explanation:

Volume of one prism = A(base prism)*height(prism)

A(base prism)= A(triangle) = 1/2*(base triangle)*Height(triangle)= 1/2*10*7 = 35 cm^2

Volume of one prism(or one candle) = A(base prism)*height(prism)= 35*6=210 cm^3

Volume of 42 candles = 210*42= 8820 cm^3

Answer:9x

Step-by-step explanation: u would just do 27-18

Answer:hey there

Step-by-step explanation:

Answer: 14 + 24 + 24 = 62

Step-by-step explanation:

I got that answer by doing 24 x 7.

We know that the area is 168, so to get the area you divide the length in half; now you have 7. (The length is 14)

All you have to do now is 168 divided by 7 and you get 24. So, now you know the rest of the sides are 24. So, 24 x 2 + 14 = 62

Please let me know if the answer is wrong, thank you.

Answer: height of the tower is 1064 feet

Step-by-step explanation:

We want to determine the height of the tower.

Assuming her line of sight of the top of the tower is a straight line, then a right angle triangle is formed. The height, h of the tower represents the opposite side of the triangle. Her distance from the foot of the tower represents the adjacent side of the triangle.

To determine h, we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Therefore,

Tan 85.7 = h/80

h = 80tan 85.7

h = 1064 feet

Answer:

The tower is 1063.97 feet.

The number of possible sets of four marbles from the bag is 126 sets, calculated using the combinations formula, C(9, 4) = 9! / [4! * (9-4)!].

To determine the number of possible sets of four marbles from a bag containing two red marbles, two green ones, one lavender one, two yellows, and two orange marbles, we can use the concept of combinations in mathematics. The formula for combinations is given by

C(n, k) = n! / [k! * (n-k)!]

where n represents the total number of items to choose from, k represents the number of items to choose, and ! indicates factorial which is the product of all positive integers up to the number.

First, we count the total number of marbles:

2 red 2 green 1 lavender 2 yellow 2 orange2 red

Thus, n=9 total marbles in the bag. We want to choose k=4 marbles out of these.

Applying the combination formula:

C(9, 4) = 9! / [4! * (9-4)!] = 126

Therefore, there are 126 possible sets of four marbles that can be chosen from the bag.

Answer:

D: (5/2x, 5/2y)

Step-by-step explanation:

A dilation is an enlargement only when the dilation factor > 1

Only 5/2 is greater than 1

Others are less than 1

Dilation is a transformation that changes the size of a figure without changing its shape. It is represented algebraically as 'y=a*x' or 'y=a*x+b', where 'a' is the scale factor. If 'a' is greater than 1, it represents an enlargement.

In algebra, a dilation is a transformation that changes the size of a figure without altering its shape. It can either enlarge (expansion) or reduce (contraction) a figure depending on the scale factor. If the scale factor is more than 1, the dilation is an enlargement. Any algebraic representation, such as 'y=a*x' or 'y=a*x+b' where 'a' is greater than 1, represents a dilation that is an enlargement. For instance, if we have y=2x, the '2' is the scale factor that determines the enlargement. The greater the number, the larger the image after dilation.

Step-by-step explanation:

Answe4.516439288 x 10²² ways

Step-by-step explanation:

The number of ways the songs in the playlist can be played involves a permutation, since order is involved.

8 rock songs can be played out of 20 in:

20P8 ways = 20!/(20-8)!

= 20!/12! = 6.033983155 x 10^13 ways

Similarly, 6 rap songs can be played from 18 in:

18P6 ways = 18!/(18-6)!

= 18!/12! = 8.892185702 x 10^12 ways

Hence, the number of ways 8 rock and 6 rap songs can be played from the disc's library is a multiplication of both permutations, which yields:

4.516439288 x 10²² ways

Answer: 5/6

Step-by-step explanation:

Over 2 there are 4 numbers 3,4,5,6 but it can be odd so also 1 works there are 6 numbers in total and 5 numbers work so

5/6

Answer:

5/6

Step-by-step explanation:

I got 5/6 because every number matches the conditions set except for two. If Glenn rolls a 1, it works because it is an odd number. If Glenn rolls a 2 it doesn't work because it's not an odd number and its not greater than 2. If Glenn rolls a 3 it works because 3 is an odd number and is greater than two, and every number after three will also work, because they are all greater than two. This way, the only number that will not match the conditions is 2, so the answer is 5/6, or 83.(3)%

The question seems to involve solving a trigonometric equation with an incomplete equation provided. It suggests the use of trigonometric identities and basic values of sin and cos at 0 degrees to simplify and solve trigonometric equations.

The question appears to be incorrectly phrased or incomplete. However, it seems to involve solving a trigonometric equation involving sine and cosine functions. To approach such equations, one common strategy is to use trigonometric identities to simplify the equation.

For instance the given expression sin x + 2 sin x cos x can be simplified using the double angle identity or factoring, allowing for easier solution. Yet, without a clear equation to solve or a specific value to find, it's challenging to provide a direct answer.

Solving trigonometric equations often requires understanding basic trigonometric functions like sin 0, which is 0, and cos, which is 1 at 0 degrees. These values are fundamental and help in simplifying equations to find solutions within a given domain, typically between 0° and 360° for high school mathematics problems.

Final answer:

The product of the provided series of numbers is 0, because multiplying any number by zero will always result in zero.

Explanation:

The product of a series of numbers is the result of multiplying all the numbers together. In this case, you have provided a list of numbers: -3, 4, 2, -5, 3, -2, 1, 0. To find their product, we multiply them one by one.

Multiplying any number by zero results in zero, which is an important mathematical rule. Since one of the numbers in the list is 0, the product of these numbers is 0 regardless of all other numbers.
