Answer:

yes

Step-by-step explanation:

Answer:

x = -17

y = -68

Step-by-step explanation:

x - y = 51

y/x = 4  so we can say that y = 4x

using substitution:

x - 4x = 51

-3x = 51

x = -17

find 'y':

-17 - y = 51

-y = 68

y = -68

check:

-17 - (-68) = 51

51 = 51

-68/-17 = 4

4 = 4

Answer:

15 mph

Step-by-step explanation:

You need to find how much each side of the table is changing each time and change that into a fraction. In this example, the change in time is .5 hours. Repeat with the other side to get 12.5 miles. Next you change it into a fraction with the distance over the time to get 12.5/.5. Type this into the calculator to get the answer which is 15 mph.

Answer:

  2

Step-by-step explanation:

y is the geometric mean of the segment lengths.

  y = √(4·1)

  y = 2

Answer:

9/15 or 60 percent

Step-by-step explanation:

Answer:

52

Step-by-step explanation:

so all of the angles added together will equal 180 and if angle qrt and angle srt are congruent then they are equal to each so first we subtract 76 from 180 and get 104. then we divide it by 2 because the two missing angles are congruent. 104/2=52 so h and j =52

Step-by-step explanation:

Answer:

10 hours

Step-by-step explanation:

The total number of hours the water is expected to reach a depth of 28 feet the second time is 2 hours and this can be determined by using the given data.

Given :

Substitute the value of y = 28 in the given function in order to determine the total number of hours water expected to reach a depth of 28 feet the second time.

[tex]\rm 28 = 7cos\dfrac{\pi x}{6}+25[/tex]

Subtract 25 on both sides in the above function.

[tex]\rm 3= 7cos\dfrac{\pi x}{6}[/tex]

Divide on both sides by 7 in the above expression.

[tex]\rm \dfrac{3}{7}= cos\dfrac{\pi x}{6}[/tex]

Further, simplify the above expression.

[tex]\rm 64.62= \dfrac{\pi x}{6}[/tex]

Cross multiply in the above expression.

[tex]\rm x = \dfrac{64.62\times 6 }{\pi}[/tex]

To convert into radian multiply the above expression by [tex]\pi/180[/tex].

[tex]\rm x = \dfrac{64.62\times 6 }{\pi}\times \dfrac{\pi}{180}[/tex]

x = 2.42 hours

x [tex]\approx[/tex] 2 hours (round off to the nearest hour)

Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]
