Answer:

4 rides

Step-by-step explanation:

Total amount = $21.50

Entry charge = $20.50

Amount left = $21.50 - 20.50 = $1

Number of rides

[tex]r = \frac{1}{0.25} = \frac{100}{25} = 4 \\ [/tex]

Another way:

[tex] 0.25\:r + 20.50 = 21.50\\

0.25\:r = 21.50 - 20.50\\

0.25\:r = 1\\

r = \frac{1}{0.25}\\

r = \frac{100}{25}\\

r = 4\\[/tex]

Answer:

15 feet

Step-by-step explanation:

Since, it's a right triangle, we will use the Pythagorean theorem formula:

[tex]a^2+b^2=c^2[/tex]

a and b are the straight sides and c is the ladder (hypotenuse).

[tex](8)^2+b^2=(17)^2[/tex]

Solve for [tex]x[/tex]:

[tex]64+b^2=289[/tex]

[tex]b^2=225[/tex]

[tex]\sqrt{b^2} =\sqrt{225}[/tex]

[tex]b=15[/tex]

The distance between the ground and the top of the ladder is 25 feet.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

Hypotenuse= 17 foot

Base = 8 feet

Now, using pythagoras theorem

H² = P² + B²

17² = P² + 8²

289 - 64 = P²

P= √225

P= 25 foot

Hence, the distance between the ground and the top of the ladder is 25 feet.

Answer:

x-intercept=-74

Step-by-step explanation:

for x-intercept (y=0)

y=83x+9

0=83x+9

-83x=-0+9

-83x=9

x=9/-83

x=-0.1

Answer:

x = -27/8

Step-by-step explanation:

y = [tex]\frac{8}{3} x + 9[/tex]

to find x intercept let y = 0 then solve for x

0 = [tex]\frac{8}{3} x + 9[/tex]

-9 = [tex]\frac{8}{3} x[/tex]

divide both sides by 3

-9x3 = 8x

-27 = 8x

Answer:

D No. as there are only 12 bolts longer than 1inch.

Mr. Slivka needs 16 bolts of greater than 1 measure, and there are only 12.

Step-by-step explanation:

We cannot include 1 inch data as this is not over 1 inch like the 1inch 2/8 and 1inch 4/8 etc. the greater measures of over 1 inch count to 12.

We know they are greater as they do not have a negative sign next to the added fraction of 1 2/8 or 1 4/8.

Answer:

1075 ft^2

Step-by-step explanation:

The figure shows two rectangles. In order to get the two areas, we should be able to find the area of each and add them together.

The formula of the area of the rectangle = L * W

First rectangle [tex]= 25 * 8[/tex] = 200

Second rectangle =  25 * 35 = 875

Adding them together would yield 1075 sq ft.

Answer:

It is x > -5

Step-by-step explanation:

Equation: -3x + 8 < 23

First, we have to move the constant to the other side. By moving it to the other side, the sign also changes becoming -3x < 23 - 8.

Now we simplify: 23 - 8 becomes 15

New equation: -3x < 15

Finally, we want the X by itself, and to do that, we must divide -3 to both sides. Keep in mind that when we multiply or divide, the sign '<' also changes.

[tex]\frac{-3x}{-3}[/tex]<[tex]\frac{15}{-3}[/tex] = x > -5

Answer:

B) f(x) ≥ 3x + 4

g of x is less than or equal to negative one half times x minus 5

Step-by-step explanation:

From the above graph,  

If point B is the solution of the system of inequalities, then point B must satisfies both inequalities  

We can see from the graph that

Point B is located above (≥) the boundary line for f(x) and is also below (≤) the boundary line for g(x).

So we can say,

Point b satisfies the inequalities

Therefore,  

The system is  

 f(x) ≥ (3x+4)

 g(x) ≤ (-1/2x -5)

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute (1, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of line

Answer:

-7y/3z

Step-by-step explanation:

When dividing fractions, we flip the second one so that we can multiply the 2 fractions. When we do this, we get 7y/6 * -2/z. When we multiply the numerators and denominators, we get -14y/6z. Simplifying (dividing the numerator and denominator by 2), we get -7y/3z.

X is 10 so both angles are 29. This means that the other angles are 151 because the whole thing must add up to 360.

Angles a, f and b also add up to 180°

Answer:

Step-by-step explanation:

Probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .

" Probability is defined as the mathematical statement which represents the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Total number of spinning colour in a spinner = 12

Number of green spinner = 3

Substitute the value in the formula to get the probability we get,

Probability of spinning green = [tex]\frac{3}{12}[/tex]

                                                 =  [tex]\frac{1}{4}[/tex]

Hence, probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .

Answer:

Direct variation: y = 3x, y = (2/7)x, and -0.5x = y

Not direct variation: x = -1, y = 2.2x + 7, and y = 4

Step-by-step explanation:

We know that the equation for direct variation is y = k · x, where you can fill in for k whatever number you want.

So, let’s figure this out by looking at the equations.

Equation 1: y = 3x

We know this is a direct variation equation because it all fits together and the 3 is a substitute for the variable, k.

Equation 2: x = -1

This is not an example of direct variation because:

1) the variable by itself on one side is x, when it is supposed to be y

2) there is only one number, -1, when instead it should say, -1x.

Equation 3: y= (2/7)x

This is an example of direct variation because the 2/7 is filling in for the k, and everything else matched the direct variation equation.

Equation 4: -0.5x = y

Since it doesn’t matter on which side y is, let’s just turn the equation around to make it simpler.

Now we have:

y = -0.5x

This makes sense because we have everything a direct variation equation needs to have plus the -0.5 substituting in for the k.

Equation 5: y = 2.2x + 7

This is also not an example of direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.

Equation 6: y = 4

This is not an example of direct variation because there is no variable x in here! We have a k, but not an x!

Hope this helps! :)

The equations represent Direct variation are y = 3x, y = (2/7)x, and -0.5x = y

The equations represent Not direct variation: x = -1, y = 2.2x + 7, and y = 4

An equation is an expression that shows the relationship between two or more numbers and variables.

We know that the equation for direct variation can be written as;

y = kx,  

Equation 1; y = 3x

This is a direct variation equation because the 3 is a correct value for the variable, k.

Equation 2: x = -1

This is not an example of direct variation because the variable by itself on one side is x, when it is supposed to be y at that place.

Equation 3: y= (2/7)x

This is direct variation because the 2/7 is filling in for the k.

Equation 4: -0.5x = y

Since it doesn’t matter on which side y is, then just turn the equation around to make it simpler.

Now we have;

y = -0.5x

This is a direct variation equation that needs to have plus the -0.5 substituting in for the k.

Equation 5: y = 2.2x + 7

This is also a direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.

Equation 6: y = 4

This is not an example of direct variation because there is no variable x. We have a k, but not an x!
