The Gonzalez family has three children.on summer break they went to an amusement park.they bought 3 child tickets for $18.50 and 2 adult tickets.If they spent a total of $104.50, how much was the price of each adult ticket?

Answer: 0.4 miles

Step-by-step explanation:

You can use the equation y=1/5x to help you figure it out where x is the days and y is the length. y=1/5(2). y=2/5 or 0.4 miles. Please vote my answer as brainliest

The road construction crew would pave 2/5 of a mile in 2 days, as they pave 1/5 mile every day.

The road construction crew paves 1/5 mile each day. If they were to work for 2 days, to find out how much they would pave, you would simply multiply the pace per day by the number of days. So, 1/5 mile * 2 days = 2/5 miles. Therefore, the crew would pave 2/5 of a mile in 2 days.

To find out how much the road construction crew would pave in 2 days, we need to multiply the amount they pave in 1 day by 2. So, if they pave 1/5 mile every day, they would pave 1/5 * 2 = 2/5 mile in 2 days.

25 can go into 212 a total of 8 times with a remainder.

 To determine how many times 25 can go into 212, we perform the division of 212 by 25.

This is a simple division problem where we are looking for the quotient, which represents the number of times 25 can be subtracted from 212 before the remainder is less than 25.

  Let's perform the division:

 [tex]\( \frac{212}{25} = 8 \)[/tex] with a remainder of 12.

This means that 25 can be multiplied by 8 to get as close as possible to 212 without exceeding it.

The difference between 212 and 200 is 12, which is the remainder.

  Therefore, 25 can go into 212 a total of 8 times with a remainder of 12."

Answer:

7/8

Step-by-step explanation:

Step 1: Change the denominators so that they are the same for both fractions

7/8 x 15 = 105/120

13/15 x 8 = 104/120

Step 2: Compare

104/120 < 105/120 = 13/15 < 7/8

The fraction 7/8 is bigger than 13/15.

To determine which fraction is bigger between 7/8 and 13/15, we need to find a common denominator. The least common multiple of 8 and 15 is 120. Now, we can convert both fractions to have the same denominator:

7/8 = 105/120

13/15 = 104/120

Since 105/120 is larger than 104/120, the fraction 7/8 is bigger than 13/15.

Answer:

6x^2 - 4y^2 + 2x^2 + 6xy

Step-by-step explanation:

Each of the adjacent sides of the rectangle has a congruent, opposite sides. The perimeter is the sum of the lengths of the 4 sides.

P = 2(3x^2 - 2y^2) + 2(x^2 + 3xy)

P = 6x^2 - 4y^2 + 2x^2 + 6xy

24.

The perimeter of a rectangle l × w is P = 2l + 2w.

We have l = 3x² - 2y² and w = x² + 3xy. Substitute:

P = 2(3x² - 2y²) + 2(x² + 3xy)      use distributive property

P = (2)(3x²) + (2)(-2y²) + (2)(x²) + (2)(3xy)

P = 6x² - 4y² + 2x² + 6xy      combine like terms

Answer:

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Step-by-step explanation:

First step is to find the area of the circle

A = pi * r^2

A = pi * 6^2

A = 36* pi

We are missing 90  degrees of the circle  or 90 out of 360.

That means we keep 360 - 90 = 270  or 270/360

The fraction we are keeping simplifies to 3/4  (divide top and bottom by 90)

Multiply the area by the fraction that we kept.

36 pi * 3/4 = 27 * pi

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Answer:

red  1/2,

blue  2/5  

The lines do not have the same slope so they are  not parallel

Step-by-step explanation:

We can find the slope of the red line by using the formula

m = (y2-y1)/(x2-x1)

  We have the points (0,1) and (2,2)

m= (2-1)/ (2-0)

  = 1/2

We can find the slope of the blue line by using the formula

m = (y2-y1)/(x2-x1)

  We have the points (0,-5) and (5,-3)

m= (-3--5)/ (5-0)

  = (-3+5)/(5-0)

  = 2/5

The lines  do not have the same slope so they are  not parallel

[tex]5x^3 +9x^2 +15x+27[/tex]

Step-by-step explanation:

If m(x) = x2 + 3 and n(x) = 5x + 9,

(mn)(x) is (m times n)(x)= m(x) times n(x)

m(x)  * n(x)

Plug in m(x) and n(x). then multiply it

m(x)  * n(x)

(x^2 + 3)(5x+9)

Apply FOIL method to multiply it

x^2 * 5x = 5x^3

x^2 * 9 = 9x^2

3*5x= 15x

3*9 = 27

Answer:

The correct answer option is C. y<= -4x + 25.

Step-by-step explanation:

Firstly, we will find out the equation of the line with the help of using two points (0, 25) and (-6, 49).

The slope (m) = [tex]\frac{49-25}{-6-0} =-4[/tex].

We know the standard form of the equation is [tex]y=mx+c[/tex] so the y-intercept (c) can be found by putting in the values of the slope and the coordinates of a point.

[tex]25=-4(0)+c\\\\c=25[/tex]

Therefore, the equation of the line is y = -4x + 25.

Now since the inequality is dealing with the value of y and we know that the values of y go vertically (up and down). So if we look at the graph, the shaded area includes the smaller values of y and the line is a solid one.

Therefore, the inequality will be y<= -4x + 25.

If you don't understand it this way, you can pick up a point and test the inequality.

Taking the easiest point (0, 0) to check.

0 <= -4 (0) + 25

0 <= 25 --- True

or

280/100  = x/40 cross multiply

9600=100x divide by 100

x=96

Step-by-step explanation:

Answer:

Option B.

Step-by-step explanation:

The given graph is of a line which is parallel to the x axis.

Let the equation of the line is y = mx + c

where m is the slope and c is a constant representing y - intercept.

Since the graphed line is parallel to x = 0

So for the values of x = 0 equation of the line will be

y = c (constant)

Therefore, Option B. Linear constant is the answer.

Jake reaches the top of the escalator because he exceeds the height of the escalator if he travels at the rate of 8.33 inches/second.

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: Jake reaches 25 inches above the ground in 3 seconds.

The unit rate of Jake's ascend is = 25/3

                                                =8.33 inches/second

If Jake rides the escalator for 15 seconds then we would climb

=8.33×15

=124.95 inches

After 45 seconds Jake would have climbed =45×8.33

                                                                          =374.85 inches

Thus after 45 seconds Jake reaches the top of the escalator.

Hence, Jake reaches the top of the escalator because he exceeds the height of the escalator if he travels at the rate of 8.33 inches/second.
