The length of the longer ladder is 50 ft. Therefore, the answer is D.

Two ladders are leaning against the wall as shown below. The length of the longer ladder can be found as follows:

The triangles formed are right angle triangle. The triangles are similar to each other.

Similar triangles are the triangles that have corresponding sides in ratio to each other and corresponding angles congruent to each other.

Therefore, using proportion,

15 / x = 3 / 10

cross multiply

150 = 3x

divide both sides by 3

x = 150 / 3

x = 50

Therefore,

The mean of Xt is 0. The autocovariance of Xt is 0, and the autocorrelation is 0 for all lags. Mean: 0. Autocovariance: 2cos(2). Autocorrelation: 2cos²(2).

The mean of Xt is the expected value of the series, which is 0, since the uniform distribution has a mean of 0.5, and when it is multiplied by 2π, it becomes 0. The autocovariance of Xt is the expected value of the product of two variables at different lags, which is 0 because the two variables are uncorrelated. The autocorrelation of Xt is the expected value of the product of two variables at different lags, divided by the product of their variances, which is also 0 since the variables are uncorrelated.

Step-by-step explanation:

Assume n is a odd number then n-1 will be even and if odd number multiply with even it will be even. So that's for n(n-1) is a even number. If you assume n is an even number then (n-1) will be odd number..Then multiplication of odd and even number will be also even number.. So n(n-1) is always even .

By solving linear equations, we will see that Shanice and Brianna will have the same amount after 6 days.

We know that Shanice has $1,750 saved in her checking account for vacation. Each day, she withdraws $125 to pay for meals & entertainment expenses. Then the amount in her account after x days is modeled by the linear equation:

S = 1,750 - 125*x

And Brianna has $550 and adds $75 each day, so she as:

B = 550 + 75*x

Both of them will have the same amount when:

1,750 - 125*x = 550 + 75*x

1,750 - 550 = 75*x + 125*x

1200 = 200*x

1200/200 = x

6 = x

Step-by-step explanation:

Therefore , the solution of the given problem of equation comes out to be x value is 79/19 and y = 18/19.

The equal symbol (=) is used in mathematical equations to denote equality between two propositions. Mathematical equations, which seem to be expressions of reality, are used to demonstrate how different numerical elements can be compared. For instance, the equal sign splits the integer 12 or the equation y + 6 = 12 into 2 different halves. One can compute how many characters each edge of a symbol has. Contradictory meanings are common in symbols.

Here,

Given :

=> x = 7 -3y

and

=> 4x -7y = 10

=> 4(7-3y) - 7y = 10

=> 28 -12y - 7y = 10

=> 28 - 19y = 10

=> 18 = 19y

=> y = 18/19

=> x = 7 - 3(18/19)

=> x =  133 - 54 / 19

=> x = 79 /19

Conditional independence depends on the nature of the third event. If you roll two dice, one may assume that the two dice behave independently of each other. Looking at the results of one dice will not tell you about the result of the second dice. (That is, the two dice are independent.)

Answer:

recipe should have 5.76 cups of sugar.

Step-by-step explanation:

To find out how many cups of sugar should be in Molly's apple recipe, you can use the proportion of sugar to apples in the recipe. Since the recipe is 36% sugary, that means for every 100 cups of apples, 36 cups of it is sugar. We can set up the proportion as:

Sugar / Apples = 36 / 100

To find the number of cups of sugar in 16 cups of apples, we can cross-multiply and divide:

Sugar = (36/100) * Apples

Sugar = (36/100) * 16

Sugar = 5.76 cups

So the recipe should have 5.76 cups of sugar.

Answer:

-1.5 and 1.5

Step-by-step explanation:

Let's call the maximum value of the function "c." The equation for the parabola is now y = x^2 + ax + (b - c).

Using the point (1,1), we can solve for "a" and "b":

1 = 1^2 + a(1) + (b - c)

1 - a + b - c = 1

c - a + b = 0

c = -a + b

And using the fact that the maximum value is -3:

-3 = -a + b

a - b = 3

Combining these two equations:

-3 = -a + b = a - b

-3 = 2a

a = -1.5

Plugging in "a" to either equation:

-3 = -(-1.5) + b

-3 = -1.5 + b

b = -1.5 + 3 = 1.5

So the values of "a" and "b" are -1.5 and 1.5, respectively.

Answer: The candle will take 16.5 cm of wax to burn out.

The initial speed of the uniform solid ball rolling smoothly along a floor inclined at 32° is 5.3 m/s.

We can use the conservation of mechanical energy to solve for the initial speed of the ball. The initial mechanical energy of the ball is equal to the final mechanical energy of the ball when it reaches the top of the ramp.

Initial mechanical energy = Final mechanical energy

1/2 mv^2 = mgh + 1/2 mv'^2

where

m = mass of the ball

v = initial speed

g = acceleration due to gravity (9.8 m/s^2)

h = height of the ramp (2.70sin(32°) = 1.43  m)

v' = final speed = 0 m/s

Solving for the initial speed, we get:

v = √(2gh) = √(2 * 9.8 * 1.43) = √(28.04) = 5.3 m/s.

So, the initial speed of the ball is 5.3 m/s.

Answer:

[tex]\sqrt{27}[/tex]

Step-by-step explanation:

because [tex]\sqrt{27} = 5.19[/tex]

so 5.19<5.34

Answer:

5.34

Step-by-step explanation:

Step 1:

First, we need to find the perfect square that is closest to but less than 27. The closest perfect square is 25 (5^2).

Step 2:

Now we need to divide the number we are trying to find the square root of (27) by the closest perfect square (25). In this case: 27/25 = 1.08

Step 3:

We can now find an approximate value for the square root of 27 by multiplying the closest perfect square (5) by the quotient obtained in step 2 (1.08). So, the approximate value of √27 is 5.40

Step 4:

In order to find a more accurate value of the square root, we can use the long division method.

Step 5:

We set up a long division problem with the dividend being 27 and the divisor being 5.

27 5

2 5

So, the quotient is 5 and the remainder is 2.

Step 6:

Now we bring down the next two digits (0) to get a new dividend of 20.

27 5

20

Step 7:

We divide 20 by 5 and get 4 as the quotient.

Step 8:

The final value of the square root of 27 is 5.4 (5 + 4/10)

Note: The process above is providing the approximate value of square root of 27, while the exact value of the square root of 27 is √27 = √(3^3) = 3.

That's why our answer is 5.34

Answer:

Answer:

37.5%

Step-by-step explanation:

General Explanation:

(1m = 100cm

2m = 200cm)

= (75cm ÷ 2m) × 100

= (75 ÷ 200 ) × 100

= 75 ÷ 2%

= 37.5%

_________________________________

Easier Explanation (Decimal to Percentage):

(1m = 100cm

2m = 200cm)

= 75cm ÷ 200cm

= 75 ÷ 200

= 0.375 (3/8 as a fraction)

= 37.5%

Andrew invested $3520 at 7.5% and $19,480 at 13%.

Let's call the amount invested in the 7.5% bond "A" and the amount invested in the 13% bond "B".

We know that:

A + B = 23,000

0.075A + 0.13B = 2,880

We can use the second equation to solve for one of the variables, then substitute that value back into the first equation to solve for the other. For example:

0.075A + 0.13B = 2,880

0.13B = 2,880 - 0.075A

B = (2880 - 0.075A) / 0.13

Substituting this expression for B back into the first equation:

A + (2880 - 0.075A) / 0.13 = 23,000

0.875A + 2880 / 0.13 = 23,000 * 0.13

0.875A = 23,000 * 0.13 - 2880 / 0.13

0.875A = 3080

A = 3520

So Andrew invested $3520 at 7.5% and $23,000 - $3520 = $19,480 at 13%.

To prove this, we can use a logical contrapositive argument. Assume that s2 is not a subset of s1, meaning there exists at least one element in set s2 that is not in set s1. Then, this means that s1 is not a subset of s2, which contradicts our original assumption that s1 ⊆ s2. Thus, we conclude that if s1 ⊆ s2, then s2 ⊆ s1.
