One hour's cost for the trampoline gym will be $12.

The ratio can be defined as the number that can represent one quantity as a percentage of another. They can be compared only when the two numbers in a ratio have the same unit. Ratios are used to compare two objects.

Given, A trampoline gym charges $6 for 1/2 of an hour.

Since,

For 1/2 hour gym charges = 6$

So from the definition of the ratio

Thus,

For 1-hour gym will charge = 6*2

For 1 hour gym will charge = 12$

therefore, One hour cost for the gym will be $12.

Step-by-step explanation:

In standard form the first term is the term with the largest exponent.

The following terms are then in descending order of exponents.

The term with the largest exponent is 7[tex]x^{7}[/tex] ← first term

Answer:

Step-by-step explanation:

A triangle that has one of his angles to be 90° is known as a right angled triangle. The triangle has one right angle and two acute angles. The three sides of the triangle are namely the hypotenuse (which is the longest side), the opposite and the adjacent. One of the side of the triangle can be written in terms of the other using the theorem called pythagoras. According to the theorem;

[tex]hyp^{2} = opp^{2} + adj^{2} \\[/tex]

Based on the values of the sides given

hypotenuse = 5cm (being the longest side)

[tex]hyp^{2} = 3^{2}+4^{2} \\ hyp^{2} = 25\\hyp = \sqrt{25}\\ hyp = 5cm[/tex]

This shows that the triangle is a right angled triangle as described by Martin since we are able to express one side in terms of the other.

Answer:

8.5

Step-by-step explanation:

So the line segment that is tangent to the circle is 8, and AO is 11.7.

When you connect them, they are perpendicular, so you have a right triangle with one unknown leg that we will call X, a leg that is 8, and a hypotenuse that is 11.7.

If you use the Pythagorean Theorem, you will find that the leg is √72.89, which is approximately 8.5.

That leg is the radius.

This might be wrong so check it.

Answer:

D

Step-by-step explanation:

you have it right :)

The function with the coordinates (1, 8) and (0, 2) is [tex]f(x)=2\times(4)^x[/tex]. Therefore, option D is the correct answer.

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

From the given graph, the coordinate points are (1, 8) and (0, 2)

Using the formula [tex]y=a\times(b)^x[/tex]

Where, a is x-intercept

Substitute, a=2 and (x, y)=(1, 8) in [tex]y=a\times(b)^x[/tex], we get

[tex]8=2\times(b)^1[/tex]

⇒ b=4

Substitute a=2 and b=4 in [tex]y=a\times(b)^x[/tex], we get

[tex]y=2\times(4)^x[/tex]

⇒ [tex]f(x)=2\times(4)^x[/tex]

Therefore, the function for the given coordinates is [tex]f(x)=2\times(4)^x[/tex].

y=4x+5

Step-by-step explanation:

Liner graph, therefore, y=mx+b; b is the y intercept; m is the slope

b=5, another pair is (-1,1)

need to find m first

Substituting we get:

⇒1= m(-1) + 5

⇒1= -1m + 5

⇒1-5= -m

⇒-4 = -m

⇒m=4

Answer:

2

Step-by-step explanation:

Answer:

5.3

Step-by-step explanation:

You use the Pythagoras theorem which is a^2+b^2=c^2.

Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.

8^2 - 6^2 = b^2

64 - 36 = b^2

b = sqrt(28)

b = 5.2915.... = 5.3

Step-by-step explanation:

Answer:

La altura de la catedral es de 15119,97 m.

Step-by-step explanation:

Para una respuesta única, la pregunta se formula de la siguiente manera:

Una catedral se encuentra en la cima de una colina. Cuando se ve la parte superior de su torre desde la parte inferior de la colina, el ángulo de elevación es de 48 °. Cuando se ve desde un punto a 6096 m del pie del promontorio, el ángulo de elevación es de 41 °, la pendiente de la colina forma un ángulo de 32 ° Se aproxima a la altura de la catedral

Deje que la base de la colina = C

El punto 6096 m de la base = A

La cima de la catedral = B

∴ ∠A = 41 °

∠C = 180-48 = 132 °

∠B = 180 - (41 + 132) = 7 °

[tex]\dfrac{6096}{sin7} = \dfrac{CB}{sin41}[/tex]

∴ CB = 32816.59 m.

Punto E = Base de la catedral.

Punto D = Punto debajo de la base de la catedral al nivel del pie de la colina

Por lo tanto, la altura de la catedral = BE

 ∡ABE = 90-41 = 49 °

∡CED = 90-32 = 58 °

∴ ∡CEB = 180 - 58 ° = 122 °

De la regla seno tenemos;

[tex]\dfrac{CB}{sin(\angle CEB)} = \dfrac{BE}{sin(\angle ECB)}[/tex]

∠EBA = 90 - 48 = 42°

∠EBC = 42 - 7 = 35°

∠ECB = 180 - 35 - 122 = 23°

[tex]\therefore \dfrac{32816.59 }{sin(122)} = \dfrac{BE}{sin(23)}[/tex]

[tex]BE = \dfrac{32816.59 }{sin(122)} \times sin(23) = 15119.97 \ m[/tex]

La altura de la catedral = 15119,97 m.

Answer:

9 packages

Step-by-step explanation:

Each package will have 6 sheets, so to find the number of packages for 55 sheets, we can just use a rule of three:

1 package -> 6 sheets

x packages -> 55 sheets

x * 6 = 55 * 1

x = 55 / 6 = 9.17

Rounding down, we have x = 9 packages.

So it can be done a total of 9 packages, and there will be (55 - 9*6) = 1 sheet left.

Order of the matrices must be the same in order to add them up

Adding matrices mean adding corresponding elements together

Order of matrix is 4 rows and 1 column

Answer:

4 x 1  ( 4 rows and one column)

Step-by-step explanation:

Recall the definition for order of a matrix: The number of rows times the number of columns.

So, in this case, we are adding matrix A which is 4 rows and 1 column to matrix B which is also of 4 rows and one column, obtaining a third matrix that has also 4 rows and one column:

[tex]\left[\begin{array}{cccc}-9\\0\\3\\-1\end{array}\right] +\left[\begin{array}{cccc}0\\4\\-6\\2\end{array}\right] =\left[\begin{array}{cccc}-9\\4\\-3\\1\end{array}\right][/tex]

The resultant A + B is also of 4 rows and one column

Answer:

We need the picture.

Step-by-step explanation:

Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.

Answer

The median is 155

Step-by-step explanation:

You get the numbers from least to greatest then the middle number is your median.
