Answer:3000:2400

Step-by-step explanation:

The ratio of British army troops to colonial army troops at the Battle of Bunker Hill is 3,000:2,400, which simplifies to 5:4.

The ratio of the number of British army troops to the number of colonial army troops at the Battle of Bunker Hill is calculated by dividing the number of British troops by the number of colonial troops. With 3,000 British troops and 2,400 colonial troops, the ratio is 3,000:2,400.

To simplify the ratio, you could divide both sides by the greatest common divisor. In this case, both numbers can be divided by 1,200 (which is the greatest common divisor of 3,000 and 2,400) to give a simplified ratio.
After dividing both numbers by 1,200, the simplified ratio of British to colonial troops is 2.5:2 or, expressed as a fraction, 2.5/2, which simplifies further to 5:4.

Step-by-step explanation:

(2/3)*6=4

6-4=2

Answer:

(4, 0)

Step-by-step explanation:

To use elimination, you need to make the coefficients of one of the variables the same in each equation.  For example, we can multiply the first equation by 2 and the second equation by 3:

6x + 4y = 24

6x + 15y = 24

Now we can subtract the equations, eliminating the x terms.

(6x + 15y) − (6x + 4y) = 24 − 24

11y = 0

y = 0

Now plug into either equation to find x.

3x + 2y = 12

3x + 0 = 12

x = 4

Answer:

D.

Step-by-step explanation:

There were 26,101 people in the athletic center at the end of game.

Step-by-step explanation:

Number of people entered = 24196

Number of people left during second half = 2914

Remaining people = 24196 - 2914 = 21282

People entered during second half = 4819

Total people at the end of game = Remaining people + People entered during second half

Total people at the end of game = [tex]21282+4819=26101[/tex]

There were 26,101 people in the athletic center at the end of game.

Step-by-step explanation:

Answer:

The number of movies that can can fit on shelf of 5 feet is 9 .

Step-by-step explanation:

Given as :

The measure of each movies case = 7 inches wide

Let the number of movies for 5 feet wide = n

Now ,

∵ 1 feet = 12 inches

∴ 5 feet = 12 × 5 = 60 inches

I.e 5 feet = 60 inches

Now, Again

For 7 inches wide  , the number of movies = 1

So, for 1 inch wide case, the number of movies = [tex]\frac{1}{7}[/tex]

∴ For 60 inches wide case, the number of movies = [tex]\frac{1}{7}[/tex] × 60

I.e For 60 inches wide case, the number of movies = 8.57 ≈ 9

Hence the number of movies that can can fit on shelf of 5 feet is 9 . Answer

Step-by-step explanation:

The elements of matrices are represented in the form

[tex]a_{r,c}[/tex]

Here r is the row number and c is the column number.

Given matrix is:

[tex]A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right][/tex]

The elements of matrix will be represented by a_{r,c}

We have to find [tex]a_{1,3}[/tex]

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

The probability of not getting an outcome less than 3 is 2/3

Step-by-step explanation:

We can solve it by finding the probability of getting a number less than 3 and then taking its complement

So,

A die is rolled then

S = {1,2,3,4,5,6}

n(S) = 6

Let p be the probability of getting a number less than 3

The numbers less than 3 are {1,2}

So,

[tex]p =\frac{2}{6}\\p = \frac{1}{3}[/tex]

Let q be the complement of p,

The sum of probability of an event's occurrence and non-occurrence is 1

So,

p+q = 1

q = 1-p

[tex]q = 1 - \frac{1}{3}\\q = \frac{3-1}{3}\\q = \frac{2}{3}[/tex]

The probability of not getting an outcome less than 3 is 2/3

The probability of rolling a fair die and not getting an outcome less than 3 is 2/3, as there are four favorable outcomes (3, 4, 5, 6) out of six possible outcomes on a fair six-sided die.

To clarify, rolling a die and not getting an outcome less than 3 means getting a 3, 4, 5, or 6. Since a fair die has 6 sides, each side has an equal chance of landing facing up, so the probability of getting any specific number is 1/6.

The outcomes that meet our condition are 3, 4, 5, and 6, which are four possible outcomes out of six. Therefore, the probability is calculated as the number of favorable outcomes over the total number of outcomes, which is 4/6. To simplify 4/6, we divide both the numerator and the denominator by the common factor of 2, which gives us 2/3.

Thus, the probability of rolling a number that is not less than 3 is 2/3.

Step-by-step explanation:

Answer:

No solution.

Step-by-step explanation:

Add similar elements: 2y + 3y = 5y

5y - 6 (y + 2) = -y + 6

Apply the distributive Law:

6y - 6 x 2 = 6y - 12

5y - 6y - 12 = -y + 6

Add similar elements: 5y - 6y = -y

-y - 12 = -y + 6

Add 12 to both sides:

-y - 12 + 12 = -y + 6 + 12

Simplify:

-y = -y + 18

Add y to both side:

-y + y = -y + 18 + y

Simplify:

0 = 18

Answer:

The value of  x = 6.

The measure of side J K = K L = J L = 83 units

Step-by-step explanation:

Here, Δ JKL is an Equilateral Triangle.

So, all sides of the triangle are equal to each other.

⇒ J K =  K L = L J

Substituting the values of each side , we get:

13 x + 5 = 17 x - 19  = 8 x + 35

Now, comparing first and second term of the above expression,we get:

13 x + 5 = 17 x - 19

⇒ 5 + 19 = 17 x- 13 x

or, 24 = 4 x

⇒ x = 24/4 = 6 , or x = 6

So, the measure of side J K = 13x   + 5 = 13(6) + 5  = 83 units

      the measure of side K L = 17x  -19 = 17(6) -19  = 83 units

       the measure of side J L = 8x  +35 = 8(6) +35   = 83 units

The inequality that models all possible prices,p, in dollars, for a pair of pants that casey can afford is P ≤ 20

Given that, Casey has at most $50 to spend on pants.  

She wants but 3 identical pairs of pants and has a $10 off coupon.  

We have to find which inequality models all possible prices,p, in dollars, for a pair of pants that casey can afford

"p" represents the price in dollars for a pair of pants that casey can afford

Now, we know that,  

Money spent casey ≤ $ 50

Cost of 3 identical pairs of pants – coupon worth ≤ 50

3 x cost of 1 pair of pant – 10 ≤ 50

3 x cost of 1 pair of pant ≤ 50 + 10

3 x cost of 1 pair of pant ≤ 60

Cost of 1 pair of pant ≤ 60/3

$ P ≤ 20

P ≤ 20

Hence, the inequality is P ≤ 20

Final answer:

The student's request for fractions between -8/10 and -4/5 cannot be fulfilled because these two fractions are equivalent. To provide a meaningful answer, it's assumed that the intended question is to find fractions between -8/10 and -9/10, for which examples are given.

Explanation:

The question is asking for five fractions that are between -8/10 and -4/5. First, notice that -8/10 is equivalent to -4/5, so we actually need to find fractions between two identical values. This is not possible as no fractions can exist between two identical numbers. However, assuming that the question intends for incremental fractions between two different numerators with the same denominator, we could consider finding fractions between -8/10 and -9/10, or between -7/10 and -8/10.

For simplicity, let's find five fractions between -8/10 and -9/10:

-17/20

-18/20

-19/20

-39/40

-79/80

These fractions are chosen because they simplify to values that lie between -8/10 and -9/10 when reduced to the same denominator.

Answer:

The value of x  in the given figure is  110°

Step-by-step explanation:

Here, In ΔABD,

AB=AD and  ∠ ABD =  35°

Now, ANGLES OPPOSITE TO EQUAL SIDES ARE EQUAL.

      As,  AB=AD

⇒ ∠ ABD =   ∠ ADB =    35°  

Now, In ΔABD,  by ANGLE SUM PROPERTY:

∠ ABD  + ∠ ADB +   ∠ DAB  =  180°

⇒ 35°   + 35°   + x  = 180°  

or,  x = 180°  - 70°  = 110°

⇒ x  = 110°

Hence, the value of x  =  110°

Answer:

110

Step-by-step explanation:

Since AB=AD, AB = 35 so that means AD = 35. 35+35=70. A triangle is 180, so 180-70=110
