lucy rolls 2 fair dice and adds the results from each. work out the probability of getting a total of 10

Answer:

The triangle whose vertices are x(3,2) y(-1,0)and z(1,-12).

=> xy = sqrt(4^2 + 2^2) = 4.472

=> xz = sqrt(2^2 + 14^2) = 14.142

=> yz = sqrt(2^2 + 12^2) = 12.166

=> Perimeter/2 = P = (xy + yz + xz)/2 = (4.472 + 14.142 + 12.166)/2 = 15.39

=> Applying Heron's formula, the area of triangle would be:

A = sqrt(P*(P-xy)*(P-xz)*(P-yz))

   = sqrt(15.39*(15.39 - 4.472)*(15.39 - 14.142 )*(15.39 - 12.166))

   = 26.001

   = ~26

Hope this helps!

Answer:

393 1/8 miles

Step-by-step explanation:

Distance driven in 1 gallon of gas  = 23  1/8 miles

23  1/8 miles is mixed fraction.

converting 23  1/8 into improper fraction

23  1/8 = (23*8 + 1)/8 = 185/8

Thus 1 gallon of gas can drive 185/8  miles. ____________1

Since distance for 17 gallons is needed.

we multiply both gallon of gas and distance with 17.

1 *17 gallon of gas can drive 185/8*17  miles

17 gallon of gas can drive (185/8)*17  miles

=>17 gallon of gas can drive (3,145)/8 miles

converting (3,145)/8  miles into mixed fraction we have 393 1/8 .

Thus,  Logan's family can drive 393 1/8 miles on 17 gallons.

(To find the x-intercept, substitut in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y. As shown in the pictur)

The x-intercept and y-intercept of the equation will be (8, 0) and (0, 20).

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The school band is selling sweatshirts and baseball caps to raise $2000 to attend a band competition.

Sweatshirts cost $25 each and baseball caps cost $10 each.

The equation 25x + 10y = 2000 models this situation.

Where x is the number of sweatshirts sold and y is the number of baseball caps sold.

Then the x-intercept will be

25x = 200

x = 8

The x-intercept will be (8, 0).

And the y-intercept will be

10y = 200

y = 20

The y-intercept will be (0, 20).

The x-intercept and y-intercept of the equation will be (8, 0) and (0, 20).

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

5.  sin 31 = opp/ hyp

  sin 31 = 34 /x

x = 34 / sin 31

x =66.0145369

tan 31 = opp /adj

tan 31    = 34/y

y = 34/ tan 31

y= 56.5855024

6.  Pythagorean theorem to find z

9^2+12^2 = z^2

81+144 = z^2

225 = z^2

z =sqrt(225) =15

sin x = opp / hyp

sin x = 9/15

take the inverse sin

x = sin^ -1 (9/15) = 36.86989765

sin y = opp / hyp

sin y = 12/15

take the inverse sin

y = sin^ -1 (12/15) = 53.13010235

Answer:

1. sin(31) = opposite/hypotenuse

sin(31) = 34/x

x = 34/sin(31) = 66.0145369

x = 66.0°

tan(31) = opposite/adjacent

tan(31) = 34/y

y = 34/tan(31) = 56.5855024

y = 56.6°

2. tan(x) = opposite/adjacent

tan(x) = 9/12

x = 36.86989765

x = 36.9°

y = 180 - 90 - x

y = 53.13010235

y = 53.1°

z² = 9² + 12²

z² = 225

Answer:

The answer is option 3.

Step-by-step explanation:

First we have to find the area of both rectangle and triangle :

Rectangle,

[tex]area = base \times height[/tex]

Let base = 9,

Let height = 3,

[tex]area = 9 \times 3 \\ area = 27 \: {m}^{2} [/tex]

Triangle,

[tex]area = \frac{1}{2} \times base \times height[/tex]

Let base = 3,

Let height = 3,

[tex]area = \frac{1}{2} \times 3 \times 3 \\ area = \frac{1}{2} \times 9 \\ area = \frac{9}{2} \\ area = 4.5 \: {m}^{2} [/tex]

Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :

[tex]area = 27 - 4.5 \\ area = 22.5 \: {m}^{2} [/tex]

Answer:

Answer:

2,5

Step-by-step explanation:

2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.

To find the solution to the equation 3x - y = 1, we can choose a value for x and solve for y. By substituting x = 2, we find that the ordered pair (x, y) = (2, 5) is a solution.

To find an ordered pair (x, y) that is a solution to the equation 3x - y = 1, we first need to choose a value for x and then solve for y. Let's choose x = 2:

Therefore, the ordered pair (x, y) = (2, 5) is a solution to the equation 3x - y = 1.

Final answer:

To calculate the number of 5-letter "words" with vowels on the ends from 'FORMULATED', you multiply the number of ways to choose the two vowels (4 x 3) by the number of ways to choose the three different consonants (6P3; 6 x 5 x 4), resulting in 1440 different possible "words."

Explanation:

To determine the number of 5-letter "words" that can be formed from the letters of the word FORMULATED with vowels at both ends, we need to consider two parts: the selection of vowels and the selection of consonants. The word FORMULATED contains four vowels (O, U, A, E) and six consonants (F, R, M, L, T, D).

First, we choose the vowels for the ends. There are 4 vowels, which means we can select the first vowel in 4 ways. After selecting the first vowel, we can still choose the second vowel from the remaining 3 vowels (since we are allowing repetitions). This gives us 4 x 3 possibilities for the vowels.

Now we select the consonants for the center three positions. We have 6 different consonants to choose from, and since each position must be filled with a unique letter, we can select these in 6P3 (6 permute 3) ways, which is calculated as 6 x 5 x 4.

Finally, to find the total number of 5-letter "words," we multiply the number of ways to choose the vowels by the number of ways to choose the consonants, giving us 4 x 3 x 6 x 5 x 4 which equals 1440 possible "words."

Answer:

5x + 2y = 3280

x+y = 785

x = 785 - y

5*(785 - y) + 2y = 3280

3925 - 5y + 2y = 3280

3925 - 3280 - 3y = 0

645 = 3y

y=645/3=215

x=785-215 = 570

Adults - 570 tickets, childs - 215 tickets.

Step-by-step explanation:

A)

The longest thing that can fit along the base of the box is sqrt ( 13^2 + 35^2) = 37.3, which is less than 38, so NO, the baton can't lay flat on a diagonal along the base of the box C. No, because the diagonal is 37.3 inches long.

B) The interior diagonal of the box is sqrt(13^2 + 13^2 + 35^2) = sqrt (1563), which is 39.5, which is greater than 38, so YES, the baton can fit along the interior diagonal of the box.

2.06 is equivalent to 2.060

The numbers 2.06 and 2.060 are equal. So, the correct symbol to represent their relationship is C. = (equal) Therefore, the correct answer is option c.

The numbers 2.06 and 2.060 have the same numerical value; they represent the same quantity. The difference between them is the way they are expressed in terms of decimal places.

2.06: This number has two decimal places.

2.060: This number has three decimal places.

However, since there are no digits beyond the third decimal place in either number, the extra zero in 2.060 doesn't change the value of the number. In other words, the two numbers are numerically identical.

Therefore, you can represent their relationship with the "equals" symbol ( = ), indicating that they are equal:

C. = (equal)

Therefore, the correct answer is option c.

Answer:

The symmetric property of congruence is:

If ∠A ≅ ∠B, then ∠B ≅ ∠A.

If, AB ≅ CB, then CB ≅ AB.

Step-by-step explanation:

Two triangles are said to be congruent if they have the same three sides and the same three angles, not necessarily the same sides or the same angles are equal.

The properties of congruence are:

Reflexive property:

For all angles A, ∠A ≅ ∠A. That is, all angles are congruent to themselves.

If AB is side of a triangle then, AB ≅ AB.

Symmetric Property:

For any angles A and B if, ∠A ≅ ∠B, then ∠B ≅ ∠A.

For sides AB and CB of a triangle if, AB ≅ CB, then CB ≅ AB.

Transitive property:

For any angles A, B and C if, ∠A ≅ ∠B, and ∠B ≅ ∠C then ∠A ≅ ∠C.

For sides AB, CB and CA of a triangle if, AB ≅ CB, and CB ≅ CA, then AB ≅ CA.

Thus, the symmetric property of congruence is:

If ∠A ≅ ∠B, then ∠B ≅ ∠A.

If, AB ≅ CB, then CB ≅ AB.

Final answer:

The symmetric property of congruence is represented by Option B: If AB ≡ CD, then CD ≡ AB, aligning with the principle that if one quantity equals another, the second equals the first as well.

Explanation:

The symmetric property of congruence states that if one geometric figure is congruent to another, then the second is also congruent to the first. This is a reflection of the more general symmetric property of equality in algebra, which states that if one quantity equals another, the second equals the first as well.

Looking at the provided options, the one that represents the symmetric property of congruence is:

Option B: If AB ≡ CD, then CD ≡ AB.

This option correctly reflects the symmetric property, which can be written as if p ≡ q, then q ≡ p where p and q are geometric figures or algebraic expressions.
