The unit rate for calories per cup is 124 and 248 calories are there in 2 cups of the cereal.

Let the calories per cup of cereal = x

According to the question,

Calories in 3/4th serving of a cup of cereal = 93

Therefore, x*(3/4) = 93

                          x = 93*(4/3)

                          x = 31*4

                          x = 124

Calories per cup of cereal = 124

Calories in 2 cups of cereal = 124*2

                                              = 248

Hence, calories per cup of cereal i.e. unit rate for calories per cup of cereal is 124 and 248 calories are there in 2 cups of cereal.

Answer: To find the certain number, we need to subtract 53 - 65:

53 - 65 = -12

Therefore, the certain number that makes the statement true is -12.

Step-by-step explanation:

The Area of Square is 81 cm².

let the side of the square which is length for both rectangles be a.

let the width of rectangle be x and y.

So, x+ y= a

sum of perimeters= 54

2 (a +x ) + 2 (a+ y) = 54

2a+ 2x + 2a+ 2y = 54

2a + 2a + 2(x+ y) = 54

4a + 2 (a) = 54

4a + 2a = 54

6a = 54

a= 54/6

a= 9

So, area of square

= 9 x 9

La edad actual de José es de 30 años.

Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.

La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.

Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.

Resolviendo esta ecuación, podemos simplificarla y llegar a: 2(x + 10) = 3[(1/2)x + 10].

Al resolver la ecuación resultante, encontramos que x = 30.

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

\(v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s\)

So, the speed of a train is 0.416 m/s.

Answer:

C. No e = h + 2

Step-by-step explanation:

The answer is (No. e = h + 2) because first of all 4 times 2/3 is 6 but 8 multiplied by 2/3 is not 10, So, A is wrong.

B is also wrong because it is basically the same thing as A.

D is not right because 6 - 2 is not 8.

So, the answer is C. No e = h + 2.

Answer:

Hope I helped!~

Step-by-step explanation:

To find the equation of the line, we can use the slope-intercept form of the equation:

y = mx + b

where m is the slope of the line and b is the y-intercept.

Using the two data points given, we can calculate the slope:

m = (11.25 - 8.35) / (1995 - 1993) = 1.95

To find the y-intercept, we can use one of the data points:

8.35 = 1.95(1993) + b

b = -3884.65

So the equation of the line is:

y = 1.95x - 3884.65

To predict the price of a box of two pieces on July 1, 1999, we can substitute x = 6 (since 1999 is 6 years after 1993) into the equation:

y = 1.95(6) - 3884.65

y = 11.7 - 3884.65

y = -3872.95

This gives us a negative price, which obviously does not make sense. It is likely that the price of a box of two pieces was not linearly increasing during this time period, or that there were other factors influencing the price. Therefore, we cannot use this equation to accurately predict the price of a box of two pieces on July 1, 1999.

the probability that x lies in the interval [0, 1] and y lies in the interval [3, 6] is 1/13.

The probability that x lies in the interval [0, 1] and y lies in the interval [3, 6] can be calculated as follows: Since x is uniformly chosen from the interval [-1, 2], the probability that x lies in the interval [0, 1] is the ratio of the length of the interval [0, 1] to the length of the interval [-1, 2]: P(0 ≤ x ≤ 1) = (1 - 0)/(2 - (-1)) = 1/3. Similarly, since y is uniformly chosen from the interval [-2, 11], the probability that y lies in the interval [3, 6] is the ratio of the length of the interval [3, 6] to the length of the interval [-2, 11]: P(3 ≤ y ≤ 6) = (6 - 3)/(11 - (-2)) = 3/13. Since x and y are chosen independently, the probability that both events occur is the product of the individual probabilities: P(0 ≤ x ≤ 1 and 3 ≤ y ≤ 6) = P(0 ≤ x ≤ 1) * P(3 ≤ y ≤ 6) = (1/3) * (3/13) = 1/13.

The simplified Expression of 2.5 x 10² / 5 x \(10^{-5}\) is 5 x \(10^6\).

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as \(3^4\), where 4 is the exponent and 3 is the base.

Given:

2.5 x 10² / 5 x \(10^{-5}\)

Now, using Exponents and powers

\(a^{-m}\) = 1/ \(a^m\)

So, 2.5 x 10² / 5 x \(10^{-5}\)

= 2.5 /5 x \(10^{2-(-5)}\)

= 25/50 x \(10^{2+5]\)

= 1/2 x \(10^7\)

= 0.5 x \(10^7\)

= 5 x \(10^6\)

Multiplying M by any matrix A would return new matrix, B, in which

• the 1st row of B is equal to the 4th row of A,

• the 2nd row of B is equal to the 3rd row of A,

• the 3rd row of B is equal to the 2nd row of A,

• the 4th row of B is equal to the 5th row of A, and

• the 5th row of B is equal to the 1st row of A.

The pattern here is

1 => 4 => 5 => 1

2 => 3 => 2

Let {4, 3, 2, 5, 1} denote the matrix M, where each number refers to the row of the identity matrix, I.

Using this notation, the pattern above gives

M² = {5, 2, 3, 1, 4}

M³ = {1, 3, 2, 4, 5}

M⁴ = {4, 2, 3, 5, 1}

M⁵ = {5, 3, 2, 1, 4}

M⁶ = {1, 2, 3, 4, 5}

so that n = 6.

(Notice that the first cycle has length 3 and the second one has length 2; the minimum n needed here is then LCM(2, 3) = 6.)

Answer:

-2

Step-by-step explanation:

Using the slope formula (y1-y2)/(x1-x2), the slope of the line is (-10-8)/(9-0), which is equal to (-18)/9= -2.

Slope of the given coordinates (9,-10) and (0,8) is -2.

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Given, coordinates of the two points,

(x₁ , y₁) = (9, -10)

(x₂ , y₂) = (0, 8)

slope m = (y₂ - y₁)/(x₂ - x₁)

             = (8 - -10)/(0 - 9)

             = (8 + 10)/-9

             = 18/-9

slope m = -2

Hence, -2 is the slope for given coordinates (9,-10) and (0,8).
