Answer:

B) 6

Step-by-step explanation:

they make one stop every 150 miles

900/150 = 6 stops

The family will make 6 stops for a trip of 900 miles.

So, the answer is B. 6.

Given is table showing number of stops made and the number of miles the family traveled.

The number of times the family stops to rest during a trip is dependent upon the number of miles the family travels.

We need to determine the number of stops the family will make for a trip of 900 miles.

To predict the number of stops the family will make for a trip of 900 miles, we can observe the pattern in the given data.

From the table, we can see that the number of stops is increasing by 1 for every 150 miles traveled.

So, to find the number of stops for 900 miles, we can divide 900 by 150 and round up to the nearest whole number since the number of stops cannot be a fraction.

900 miles / 150 miles = 6

Therefore, the family will make 6 stops for a trip of 900 miles.

So, the answer is B. 6.

Answer:

1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.

Step-by-step explanation:

Okay so lets think about this by first looking at the graph we are given.

Whatever is going on, its going up, and steadily. There's no points were the line goes down or curves, right? So it's constant and forward. So now let's look at the possible answers.

1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.

Is is constant? Yes, the rate is 10 cm/hr. Does it stop? No, you don't take a break. Is it forward? Yes, you are making more of the necklace, not less.

Thinking of the y-axis as amount of necklace made, and x-axis as time spent, this is the right graph.

So this is your answer!! Just to be sure, let's look at the other possible answers.

2. The height of a balloon as it rises, gets caught in a tree, then continues to rise.

This is not constant, because it gets stuck and stops. But it is forward, because it is rising.

Thinking of the y-axis as the height of the balloon, and x-axis as time passed, this is NOT the right graph.

This is not the answer.

3. The total distance you are from home if you ride your bike three mi/hr for 1 hour, then stop for a rest.

It is not constant, because you stop and take a break. But it is forward, because you are moving forward.

Thinking of the y-axis as the speed or distance from home, and x-axis as time passed, this is NOT the right graph.

This is not the answer.

4. The volume of water in a bath tub as it is draining.

This one IS constant, but in the wrong direction. The tub is draining, not filling, so the amount is decreasing. This would be the correct graph, if the slope were negative and the line was like this \ and not like this /.

Thinking of the y-axis as the amount of water in the tub, and x-axis as time passed, this is NOT the right graph.

This is not the right answer.

These leave us with the first answer as being correct.

Answer:

does not represent a linear function.

Step-by-step explanation:

For the function to be linear, the slope must be the same for every poknt along the function. If is not, then is not a linear function.

Let us now calculate the slope;

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

We shall take the first two points

[tex]m = \frac{4 - 2}{2 - 1} \\ m = \frac{2}{1} \\ m = 2[/tex]

Next we shall take the 2nd and 3rd points

[tex]m = \frac{8 - 4}{3 - 2} \\ m = \frac{4}{1} \\ m = 4[/tex]

The slope is not the same for these two different point, hence this table does not represent a linear function.

Answer:

[tex]23^{o}[/tex] and [tex]23^{o}[/tex]

Step-by-step explanation:

An isosceles triangle has two of its sides and angles to be equal. Let each of the unknown equal angles be represented by x. Since one of its angles measures  134°, then;

x + x +  134° = [tex]180^{o}[/tex]

2x + 134° = [tex]180^{o}[/tex]

2x = [tex]180^{o}[/tex] - 134°

    = 46

x = [tex]\frac{46}{2}[/tex]

  = [tex]23^{o}[/tex]

x = [tex]23^{o}[/tex]

The other angles that could be in the isosceles triangle are [tex]23^{o}[/tex] and [tex]23^{o}[/tex].

12 are girls

16 are boys

the question is, what percent of 28 is 16

b/c that's how likely it would be to pick a boy in a random pick

16/28=0.571428

so about 57 %

or 57 out of 100

Answer: 16/28 or 8/14 or 57%

* they all are equal so it doesn’t matter with of the three you pick *

Steps:

28 - 12 = 16

16/28 = .5714

57.14%

Answer:

5.6715 * 10^26 kg

Step-by-step explanation:

Given that :

Mass of earth = 1/95 the mass of saturn

If Mass of earth = 5.97 x 10^24 kg

Let the mass of saturn = x

5.97 x 10^24 kg = 1/95 * x

5.97 x 10^24 kg = x / 95

x = 95 * 5.97 x 10^24 kg

x = 567.15 * 10^24

x = 5.6715 * 10^26 kg

Mass of saturn = 5.6715 * 10^26 kg

Answer:

Inequality representation :

18 + 25t ≤ 143 ;

t = 5

Step-by-step explanation:

Given that:

Initial dive, I = 18 feets

Descent rate, r = 25 feets / minute

Maximum depth reached = 143 feets

Time = t

Inequality representation :

18 + 25t ≤ 143

To solve for t

25t ≤ 143 - 18

25t ≤ 125

Divide both sides by 25

25t / 25 ≤ 125 / 25

t ≤ 5

Answer:

14 cm

Step-by-step explanation:

this is because of the far left side of the shape being 6cm and as well as with the 8 cm from one side of the shape being another component to the origin of the side length, this would give us the equation 6 + 8 with out sum coming out to 14 cm being identified as the right unknown length.

y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
