level is 14.7 pounds per square inch (psi). The pressure increases 0.445
psi for each foot of depth. Suppose the pressure on a diver is 32.5 psi. How deep is he?

Answer:

1/10

Step-by-step explanation:

8 black marbles, 5 white marbles and 12 red marbles = 25 marbles

P(red) = red/total = 12/25

Remove the marble

8 black marbles, 5 white marbles and 11 red marbles = 24 marbles

P(white) = white/total = 5/24

P(red, remove,white) = 12/25 * 5/24

                                   =12/24 * 5/25

                                   =1/2 * 1/5

                                   =1/10

Step-by-step explanation:

Total balls = 12 + 5 + 8 = 25 marbles

Probability of getting white marbles = 5/24

Probability of red marbles = 12/24 = 1/2

Now

Probability = 1/2 × 5/24 + 1

Probability = 1/2 × 5/25

Probability = 5/50

Probability = ⅒

Answer:

19, 20, 21

Step-by-step explanation:

You can trial-and-error this where you test each answer out step-by-step or you can graph it and you'll see it will be a line for x = 21 and a shaded region to the left of that (if you get what I mean) and from there, any point on the line x = 21 or any point in the shaded region, will be a viable solution.

Simplifying,

Answer:

-8 and -6.

Step-by-step explanation:

Let the first even integer be a.

Since the second is a consecutive even integer, it is given by (a + 2).

Half of the smaller (i.e. a) is equal to two more than the larger (i.e. a + 2). In other words:

[tex]\displaystyle \frac{a}{2} = (a + 2) + 2[/tex]

Solve for a:

[tex]\displaystyle \begin{aligned}\displaystyle \frac{a}{2} &= (a + 2) + 2\\ \\ \frac{a}{2} &= a + 4\\ \\ a &= 2a + 8 \\ \\ a &= -8 \end{aligned}[/tex]

In conclusion, the two even, consecutive integers are -8 and -6.

Answer:

the answers are a and c

Step-by-step explanation:

to find the proportions used, you would do 8/3 or 5/a, which are equal, so that gives c.

now, pretend that the second triangle is the original and the second one is the copy (proportionately). then, to find the proportions, you would do 3/8 or a/5, which gives you a.

Answer:

y is the dependent variable and x is the independent variable

Step-by-step explanation

The number on the right of the equal sign is always the independent variable and the number on the left is always the dependent variable.

independent variable = dependent variable +5

A.)

Total Number of students = 60

Since each candidate passed in atleast one of English and Math ; the none of the students failed.

Percentage who passed :.

Mathematics only = 20%

English only = 40%

Since, no one failed ; percentage that passed both = 100% - (40+20)% = 40%

Number who passed Mathematics only :

20% × 60 = 12 students

Number that passed English only :

40% × 60 = 24 students.

Number that passed both = (40% × 60) = 24 students

Number that passed English = (Number that passed English only + Number that passed both) = 24 + 24 = 48

.Number that passed mathematics = (Number that passed Maths only + Number that passed both) = 12 + 24 = 36

2.)

Total daddy has = 50

Half given to mummy = 1/2 × 50 = 25

Amount given to houseboy = 10

Amount left = 50 - (25 + 10) = 15

Fraction of Amount left = 15/50 = 3/10

C.)

Length of cuboid = 12

Height = 8 cm

Volume of cuboid = 480

Width = w

Recall :

Volume = Length × width × height

480 = 12 × 8  × w

480 = 96w

w = 490 / 96

w = 5

Width of the cuboid = 5

The surface area of a cuboid : 2(lh + lw + hw)

Hence,

2([(12×8) + (12×5) + (8 ×5)]

2(96 + 60 + 40)

2(190)

Answer:

Wilbur Wright was 36 and his brother Orville was 32 in 1903

Answer:

2,304in^3

Step-by-step explanation:

The formula for volume is [ b * l * h ]. We can use the values we are given to find the volume of both rectangles then add them both together.

12 * 12 * 6 = 864in^3

18 * 10 * 8 = 1,440in^3

Add them both together.

864 + 1440 = 2,304in^3

Answer:

A would be 2

B would be 8

Step-by-step explanation:

It's a little hard to explain, but take the function and put it where the variable is. So, for "A" the equation would be [tex]f(1)=2^1[/tex]

Answer:

40-15x=18

Step-by-step explanation:

Multiply both sides of 2 - 3/4x = 9/10 by twenty to get

20*2 - 20*3/4*x = 20*9/10

which is 40 - 15x = 18

This should be as far as you need to go, but incase you need to go further,

subtract 40 to both sides

multiply both sides by -1 to get rid of the negatives infront of the x

then divide both sides by 15 to get

x=22/15

and yes, when you solve for x, it is a fraction, but just incase if its needed, I included it. Hope this helps in the future! Let me know if any more questions you have on this problem.

Answer:

Ratio should be equal so ratio is 3:3

The ratio of the triangles to circles in the diagram below would be; 1: 1

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained.

Thus, there are three circles and three triangles shown in the figure.

Therefore, the ratio will be;

three circles: three triangle

3 : 3

1: 1

This formula for finding the end point from the midpoint and the other end can be derived from the fact that the midpoint is the average of the endpoints.

  M = (F+G)/2
