Ryder shot a model rocket over an area that consists of two grassy areas, shown in green, and an area with no grass, shown in white. a square is split into 3 sections. the bottom section is 5 acres, the middle section is 30 acres, and the top section is 15 acres. the top and bottom sections are shaded. what is the probability that his model rocket has landed in a grassy area? 0.2 0.3 0.4 0.6

Answer:

250

Step-by-step explanation:

1. Find the total amount of people interviewed

You asked 15 students over 4 periods of lunch. That means you have to multiply:

15 x 4 = 60. You asked 60 people total.

2. Solve

You know that 25 people chose pizza out of the 60 people that you interviewed. That would make a fraction: 25/60

Now, there are 600 people, and the question is asking you how many people will get pizza based on the ratio of 25/60

So, in this case, 25/60 = x/600

You have to multiply 60 by 10 to get 600 as your denominator.

So, similarly, you have to multiply 25 by 10 to keep the same ratio.  

25 x 10 = 250

Hence, 250/600 people will buy pizza.

Answer:

x = 6

Step-by-step explanation:

: 4(x + 5) = 9x + 4x − 34

Combine Like Terms:

- 4x + 20 = 9x + 4x − 34

- 4x + 20 = 13x − 34

Subtract 20 from both sides:

- 4x + 20-20 = 13x − 34-20

Subtract The numbers:

= 4x = 13x - 54

Subtract 13x from both sides:

= 4x-13x = 13x - 54-13x

Combine Like terms:

- 9x = -54

Divide both sides by the same factor:

-9x / -9 = -54 / -9

Cancel terms that are in both the numerator and denominator:

x = -54/-9

Answer:

The answer is D because if you reflect across the y-axis then the x-axis you get D

Answer:

C

Step-by-step explanation:

the 50 miles don't really matter in this situation. 180$ per hour will be 180h (as we don't know the number of hours used) and the 50$ gas fee, which is what C is representing.

Answer:

C:  C = 180h + 50

Step-by-step explanation:

180 per hour, with h representing how many hours, and then  you need a $50 gas fee. So, the answer would be C = 180h + 50

The domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)

Range of a function is the set of all the possible output values which are valid for that function.

The function given in the problem is,

[tex]y=\sqrt{x+5}[/tex]

This function is defined when the value of √(x+5) is greater than or equal to 0.

[tex]\sqrt{x+5}\ge0[/tex]

Solve it further,

[tex]\sqrt{x+5}\ge0\\(x+5)\ge0\\x\ge-5[/tex]

Thus, the domain of the equation is [-5,0). Now for the range,

[tex]x+5\ge0\\\sqrt{x+5}\ge0\\y\ge0[/tex]

Thus the range is  [0,∞).

Hence, the domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)

Step-by-step explanation:

due to her having triplits it will be a 1/3 chance that they will all be boys because you need to take in account the three children

Answer:

Step-by-step explanation:

There are 8 different ways that the order of the children is 1/8 for each one.

So for boy * boy * boy = 1/2 * 1/2 * 1/2 = 1/8

All of the other possibilities also produce 1/8 because each child has a possibility of 1/2 to be a boy or a girl.

The value of k, the constant of variation from the given joint variation as evident from the task content is -2.

a = k × b × c

Step-by-step explanation:

you would call those alternate exterior angles meaning that they are the same angle, so all you have to do is reverse the equation meaning you do 75-15=60 and you would then divide by 2 to get X so 60/2=30, so x=30

Answer:

x = 30

Step-by-step explanation:

2x+15 should be vertical to angle 5

75 is vertical to angle 4.

If we were to look at angles 4 and 5 those are alternate interior which means they have to be congruent.

Step-by-step explanation:

Hello!

An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.

Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.

A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.

x-intercept : (-1.2,0)
