Answer:

you can go on a maximum of 11 rides

Step-by-step explanation:

you first have to subtract 30 from 100 since that is the admissons fee.

So now you are left with 70 dollars.

You divide 70 by 6 since you need 6 dollars to go on each ride.

and 70 divided by 6 is 11.6666666667 but round it to 11 since that the whole number you're left with.

hope this helped :)

Answer:

Step-by-step explanation:

Let the third interior angle be x

Since it's a triangle , all it's interior angles sum up to 180°

To find the third interior angle , add up the two of the equivalent angles that's 34 and subtract it from 180

We have

x + 34 + 34 = 180

x + 68 = 180

x = 180 - 68

We have the final answer as

Hope this helps you

Answer:

The Answer To This Question Would Be 116

Step-by-step explanation:

Step One. 34 + 34 = 68

Since Two Of The Angles Are Each 34 Degrees We Want To Add Them Both Up That Way We Get 68 Which Leads To Another Step To Find The Measure Of The Third Interior Angle.

Step Two. 180 - 68 = 116

We Got 180 Because Every Triangle No Matter What Type It Is It Will Always Equal To 180 Degrees.

With That Being Said, The Answer To This Is 116.

Answer:

  4 kg : 12 kg : 20 kg

Step-by-step explanation:

The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...

  (36 kg)/9 = 4 kg

Multiplying the given ratio by 4 kg will show the appropriate division:

  1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg

Let the number in the Spanish Class = x

Then the number in the Geometry Class = (4/5) x

Equation

x + (4/5)x < 54

Solution

x + (4/5)x < 54

4/5 = 0.8

x + 0.8x < 54

1.8x < 54                    Divide both sides by 1.8

1.8x / 1.8 < 54/1.8

x < 30

The sign used in the equation is less than, not less than or equal to.

The number of students taking Spanish cannot equal 30. There must be 29 in the Spanish Class.

\((x+8)+4x = 7x -16\\\\\implies 5x +8 = 7x -16\\\\\implies 7x -5x = 8+16 \\\\\implies 2x = 24\\\\\implies x = \dfrac{24}2\\\\\implies x= 12\)

It depends on the country and it depends on the act itself.

In US, there is such thing as freedom of speech (with some common-sense limitations), however same will get a person thrown in jail and sentenced to death in a country where any speaking out is deemed as illegal.

Then add -12 to 17 which equals 5

Use an additive or reduction formula to determine an expression as a fractional derivative of one number, which is provided as -1/2.

Now, According to the question:

What do trigonometry's fundamentals entail?

The three basic trigonometric operations are sine, cosine, and tangent. Cotangent, radial basis, and cotangent functions are all built on these three fundamental functions. All trigonometry concepts are built on top of these functions. The learning of trigonometry is not really easy until pupils are familiarized with all the terms and formulae. As a result, it is suggested that students learn each of these and practice responding to test questions from prior years.

The expression is given as:

cos(13/15)cos(-/5)-sin(13/15)sin(-/5)

This has the format of a trigonometry identity -

Cos (A+B) = Cos A Cos B - Sin A Sin B

Then = Cos ( 13π/15 + (-π/5) )

= Cos( 10π/15)

= Cos( 2π/3)

= Cos(120°)

= cos (90° + 30°)

=  -sin 30°

= -1/2

Hence, Cos(13/15)Cos(-/5)-Sin(13/15)Sin(-/5) = -1/2

There are 3,003 ways to choose 10 players out of 15 people to take the field.

There are different ways to approach this problem, but one common method is to use the combination formula.

The number of ways to choose 10 players out of 15 is given by the formula, where C(n, r) represents the number of combinations of k items that can be selected from a set of n items.

\(^{n}C_{r} =^{15}C_{10}\)

      = \(\frac{15!}{(15-10)!.10!}\)

      = \(\frac{15!}{(5)!.10!}\)

      = 15 x 14 x 13 x 12 x 11 / 5 x 4 x 3 x 2 x 1

      = 3,003 ways.

Therefore, there are 3,003 ways to choose 10 players out of a team of 15 players to take the field.

Answer:

3. (-4/5, -3) 6. (4, 12/-5)

Step-by-step explanation:

3. so first we have

-5x - 10y = 20

-5x - 8y = 14

so first we have to have the x's be opposite so we multiply the top one by -1 which gets us

5x + 10y = -20

-5x - 8y = 14

then we cancel out the x's and subtract 10 by 8 and -20 by 14 so it's now

2y = -6

then we divide by 2 on both sides so it's

y = -3

but now we have to solve for x so we substitute y in on the bottom equation so now it is

-5x - 8(-3) = 20

now we multiply

-5x + 24 = 20

subtract 24 from both sides

-5x = -4

divide by -5

x = -4/5

then put it in coordinates

(-4/5, -3)

6. so we have

x = 4

-4x - 5y = 4

so first we have to substitute the top in for the bottom so now we have

-4(4) - 5y = 4

distribute

-8 - 5y = 4

add 8 to both sides

-5y = 12

divide

y = 12/-5

coordinates

(4, 12/-5)

Perimeter = 2 (l + b)

2x² + 4x - 4y = 2 {(2x - 3y) + b}

2x² + 4x - 4y = (4x - 6y) + 2b

2x² + 4x - 4y - (4x - 6y) = 2b

2x² + 4x - 4y - 4x + 6y = 2b

2x² + 2y = 2b

(2x² + 2y)/2 = b

x² + y = b

No, a reaction does not occur when aqueous solutions of chromium(II) bromide and aluminum acetate are combined. To determine if a reaction occurs between chromium(II) bromide (CrBr2) and aluminum acetate (Al(CH3COO)3).

We need to consider the solubility rules and potential chemical reactions between the ions. According to the solubility rules, bromides (Br-) are generally soluble in water, and acetates (CH3COO-) are also soluble. Therefore, both chromium(II) bromide and aluminum acetate will dissociate into their respective ions when dissolved in water.

The ions present in chromium(II) bromides are Cr2+ and Br-. The ions present in aluminum acetate are Al3+ and CH3COO-. When these solutions are combined, there are no double replacement reactions or precipitation reactions that occur between the ions.

Since there is no reaction between the ions, we can conclude that no new compounds or products are formed. Hence, the answer is that no reaction occurs when aqueous solutions of chromium(II) bromide and aluminum acetate are combined. As no net ionic equation is required in this case, the explanation above is sufficient to state that there is no reaction between chromium(II) bromide and aluminum acetate.

Using the line of the best fit, we have"

(x, y) = (8, 1) and (0, 8)

A linear equation is represented as

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 9-x²

first, Area = x × y

Area = x(9-x²)

Now,
