Answer:

h = 20 cm

Step-by-step explanation:

The volume (V) of a square based prism is

V = area of base × h ( h is the height )

area of square base = 9 × 9 = 81 cm²

Hence

81h = 1620 ← equation to be solved

Divide both sides by 81

h = 20 cm

There is no solution for the given equation |x+5|=−3.

Two or more expressions with an Equal sign is called as Equation.

The equation |x+5| = -3 has no solutions in the real number system because the absolute value of any real number is always non-negative, and can never be negative.

Therefore, there are no values of x that make the left-hand side of the equation equal to -3, and the equation has no solutions.

Graphically, this means that there is no point on the number line where the distance from that point to -5 is equal to -3.

The solution set for the equation |x+5| = -3 is the empty set .

Hence, for the given equation |x+5|=−3 has no solution.

Answer:

[tex]y = -\frac{1}{3}x - 5[/tex]

Step-by-step explanation:

To write the equation of a line use the point slope formula [tex]y - y_1 = m(x-x_1)[/tex]. Find m by using the slope formula with the points.

[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}[/tex]

Since the line is parallel, it will have the same slope.

Substitute m = -1/3 and (-3,-4).

[tex]y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5[/tex]

Final answer:

The equation of the line that passes through the point (-3, -4) and is parallel to a given line is y = -1/3x - 5. This is found by calculating the slope of the given line and then using the point-slope form to find the equation for the parallel line.

Explanation:

The student has asked for the equation of a line that passes through point
(-3, -4) and is parallel to another line. First, we need to find the slope of the given line that passes through points (-5, 1) and (7, -3). The slope (m) is calculated by using the difference in y-coordinates over the difference in x-coordinates (rise over run), which is:

m = (y2 - y1) / (x2 - x1) = (-3 - 1) / (7 - (-5))

m = (-4) / (12) = -1/3

Since parallel lines have the same slope, our new line will also have a slope of -1/3. Using the point-slope form of a line's equation, y - y1 = m(x - x1), and substituting the point (-3, -4) and the slope -1/3, we get the equation of the parallel line:

y - (-4) = -1/3(x - (-3))

y + 4 = -1/3(x + 3)

To write it in slope-intercept form (y = mx + b), we distribute the slope and simplify:

y + 4 = -1/3x - 1

y = -1/3x - 5

Therefore, the equation of the line parallel to the given line and passing through the point (-3, -4) is y = -1/3x - 5.

Answer:

Refer to step-by-step.

Step-by-step explanation:

12.  x = 28

BC = x

AB = 96

AC = 100

We use the Pythagorean theorem to find the value of x.

a² + b² = c²

x² + 96² = 100²

x² + 9216 = 10000

x² = 10000-9216

x² = 784

√x² = √784

x = 28

13. x = 64

a² + b² = c²

48² + x² = 80²

2304 + x² = 6400

x² = 6400 - 2304

x² = 4096

√x² = √4096

x = 64

14. YES and 25 = 25

a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

So this means that AB is tangent to the circle.

15. NO and 45 ≠ 49

a² + b² = c²

3² + 6² = 7²

9 + 36 = 49

45 = 49

So this means the AB is not tangent to the circle.

16. x = 4.5 and P = 52

To find the value of x, we need to determine the value of our hypotenuse.

QU is congruent to QT, therefore, QT = 4

UR is congruent with SR, therefore, UR = 13

PS is congruent to AB, therefore:

2x = 9

Divide both sides by 2

x = 4.5

The perimeter of a triangle is:

P = a + b + c

a = 9 + 4 or 13

b = 2(4.5) + 13 or 22

c = 4 + 13 or 17

P = 13 + 22 + 17

P = 52

17. x = 13 and P = 72

TJ is congruent to UJ, therefore, TJ = 13

x = 13

The perimeter of a parallelogram is:

P = 2(a+b)

a = HR + RK

b = KU + UJ

a = 13 + 5 or 18

b = 5 + 13 or 18

P = 2(18 + 18)

P = 2(36)

P = 72

18. x = 8 and P = 80

We know that part of the whole of 26 is 18 because one side is congruent to 18.

to find the value of the other half, we simply subtract 18 from 26.

26 - 18 = 8

x is congruent to 8, therefore x = 8

The line segment 14 is congruent to the opposite segment of x, therefore making the value 14.

So then we have:

a = 8 + 14 or 22

b = 26

c = 18 + 14 or 32

P = a + b + c

P = 22 + 26 + 32

P = 80

19. x = 6 and P = 52

Now we have the case of x + 2 is congruent to 8.

x + 2 = 8

Combine like terms.

x = 8 - 2

x = 6

Now that we have the value of x, we can simply look for the value of the line segment attached to it.

4 is congruent to the line segment attached to x + 2, therefore the value is 4.

To find the perimeter we have to add all sides together.

P = (8+5)+(5+9)+(9+4)+(8+4)

P = 52

20. x = 5, y = 2, z =10, and P = 68

Let's take this one step at a time.

First we look for x.

2x + 2 = 3x - 3

Combine like terms.

2x - 3x = -3 - 2

-x = -5

Divide both sides by -1.

x = 5

Now let's get the value of y.

5y - 2 = 3y + 2

Combine like terms.

5y - 3y = 2 + 2

2y = 4

Divide both sides by 2.

y = 2

Now let's look for z.

34 - 2z = z + 4

Combine like terms.

-2z - z = 4 - 34

-3z = -30

Divide both sides by -3.

z = 10

Now that we have the values of x, y, and z. We can substitute them to find the values of our segments.

2x + 2

2(5) + 2 = 12

3x - 3

3(5)-3 = 12

5y - 2

5(2) - 2 = 8

3y + 2

3(2) + 2 = 8

z + 4

10 + 4 = 14

34 - 2z

34 - 2(10)

34 - 20 = 14

Now that we have our values let's look for our perimeter.

P = a + b + c

P = (12 + 8) + (12 + 14) + (14 + 8)

P = 20 + 26 + 22

P = 68

Answer: 2/33 hoped this helped you

Step-by-step explanation:

The probability that Lucia picks a red marble first and a white marble second from the bag without replacement is

2 / 33, found by multiplying the individual probabilities of each event. Hence option C is correct.

The question asks about the probability that Lucia randomly picks a red marble first and a white marble second from a bag containing marbles of various colors, without replacement. To calculate this probability, we need to consider the total number of marbles and the number of favorable outcomes for both events happening consecutively.

With 4 red and 2 white marbles in the bag, the probability of picking a red marble first is

P(Red) = Number of red marbles / Total number of marbles

P(Red) = 4 / 12 = 1 / 3

After picking a red marble, there are 11 marbles left, including 2 white marbles. The probability of then picking a white marble is

P(White | Red) = Number of white marbles / Total number of marbles remaining

P(White | Red) = 2 / 11

The combined probability is then the product of the two individual probabilities:

P(Red and White) = P(Red) X P(White | Red)

P(Red and White) = (4 / 12) X (2 / 11)

P(Red and White) = 8 / 132 =  2 / 33.

Thus, the correct answer is 2 / 33, which corresponds to option C.

Step-by-step explanation:

360 Oranges=40L

40*3/2=60

360*3/2=540

Answer:

540

Step-by-step explanation:

First you have to divide 360 by 40. 360/40 = 9. So that means 9 oranges are needed to make 1 L of fresh squeezed juice.

Now since you know how many oranges are needed for 1 L, you have to find out how many are for 60. To do that you need to multiply 60 and 9. 60*9 = 540.

540 is your answer.

Answer:

11, 13 and 15.

Step-by-step explanation:

Let's say that the odd number is "x". If x is for example 15, then the next ODD number would be 15+2=17 and the one after that would be 15+2+2=15+4=19.

Applying that here, we get:

Odd number* the next odd number*the next odd number=2145

x*(x+2)*(x+4)=2145

x*(x^2+4x+2x+8)=2145

x^3+6x^2+8x=2145

By solving the polynomial, you get x=11.

Which makes our three numbers: 11, 13 and 15.

11*13*15=2145. The answer checks.

Final answer:

To find the three consecutive odd numbers whose product is 2,145, set up and solve an equation for n, the first odd number. The solution is n = 11, so the three consecutive odd numbers are 11, 13, and 15.

Explanation:

To find the three consecutive odd numbers whose product is 2,145, we can set up an equation and solve for n, the first odd number:

Let n be the first odd number

Then, the next two consecutive odd numbers would be n + 2 and n + 4

We can write the equation as: n x (n + 2) x (n + 4) = 2,145

Expanding this equation, we have: n³ + 6n² + 8n - 2,145 = 0

By factoring or using a numerical method, we can find that n = 11

So, the three consecutive odd numbers are 11, 13, and 15.

Answer:

The answer is C.

Step-by-step explanation:

Think about it as substitution.

The equation given to you is 15n=10.

They are telling you that n is equal to 2/3.

So now, this is where you do the substitution.

1. Substitute 2/3 in for n.

  15(2/3)=10

2. Determine if true.

  15·2/3=10

3. Are they the same?

  10=10

So now you know your answer is C. :)

Your answer is A

Answer:

l = 7 in; w = 3 in

Step-by-step explanation:

The formula for the area of a rectangle is

A = lw

Data:

A = 21 in²

l = w + 4

Calculation:

                 21 = (w + 4) × w

                 21 = w² + 4w

w² + 4w - 21 = 0

(w + 7)(w - 3) = 0

w + 7 = 0     w - 3 = 0

      w = -7         w = 3

We reject the negative value, so w = 3 in.

21 = l × 3

l = 7

The rectangle is 7 in long and 3 in wide.

Amanda could eat 3/8 of her pizza and Lauren could eat 2/3 of her pizza.

To find out how much pizza Amanda and Lauren each eat, let's start with Cami who eats 1/2 of her pizza. Since Amanda eats less than Cami, we can represent her fraction as a fraction smaller than 1/2. For example, Amanda could eat 3/8 of her pizza. On the other hand, since Lauren eats more than Cami, we can represent her fraction as a fraction larger than 1/2. For example, Lauren could eat 2/3 of her pizza.

The measure of angle ALO = 35°

Step-by-step explanation:

* Lets talk about the tangents to a circle drawn from a point

 outside the circle:

- They are equal in length

- They are perpendicular to the radii at the point of tang-ency

- If we join the points of tang-ency withe the center of the circle

 and join the outside point with center of the circle, we

 formed two congruent triangles

* Now lets check our problem

- AL and LB are two tangents to the circle O ant points A and B

∴ LA = LB ⇒ (1)

- OA and OB are radii in circle O

∴ OA = OB ⇒ (2)

∴ OA ⊥ AL and OB ⊥ BL ⇒ radius and tangent

∴ m∠OAL = 90° , m∠OBL = 90

∴ m∠OAL = m∠OBL ⇒ (3)

* From (1) , (2) , (3)

- The two triangles LAO and LBO are congruent ⇒ SAS

- SAS is one case of congruence

∵ The lengths of two sides and the measure of the including

  angle between them in one triangle equal to the

  corresponding sides and angles in the second triangle,

  then the two triangles are congruent

∴ m∠LOA = m∠LOB

∵ m∠AOB = 110°

∴ m∠LOA = m∠LOB = 110/2 = 55°

* In ΔLAO

∵ m∠ LAO = 90° , m∠LOA = 55°

∴ m∠ALO = 180 - (90 + 55) = 180 - 145 = 35°

* The measure of angle ALO = 35°

Answer:

  1400 km/hour to the east

Step-by-step explanation:

We assume the jet is flying directly toward US airspace, so is flying east. The speed is ...

  speed = distance/time

  speed = ((8400 km)/3)/(2 h) = 1400 km/h

The jet's velocity is 1400 km per hour to the east.

Final answer:

The velocity of the supersonic jet traveling one-third of the way to U.S. airspace is 1400 km/h to the east, calculated by dividing the distance covered (2800 km) by the time taken (2 hours).

Explanation:

The supersonic jet's velocity can be determined by calculating the distance it flew and the time taken to cover that distance. The jet started 8400 km west of U.S. airspace and flew one-third of that distance, which is 2800 km (8400 km / 3). It took 2 hours for the jet to cover this distance. So, to find the velocity, we use the formula velocity = distance / time.

V = 2800 km / 2 hours = 1400 km/h to the east.
