Daniel has 102 stamps. Manuel has twice as many stamps as Daniel. Kendra has twice as many stamps as Manuel. How many stamps do they have in all?

Answers

Answer 1

Answer:

They have 714  stamps in all.

Step-by-step explanation:

Daniel has 102 stamps, and since Manuel has twice that, u multiply it two.

102 x 2 = 204.

Multiply THIS amount by two to get kendra's amount.

204 x 2 = 408.

Then, add 102, 204, and 408.

102 + 204 + 408 =  714

Answer 2

Answer:

There are 714 total stamps.

Step-by-step explanation:

Daniel has 102 stamps, so 102 is our first number.

Manuel has 2x as many stamps as Daniel (who has 102) so we do...

102 x 2 = 204

204 is our second number.

Kendra has 2x as many as Manuel (who has 204).

204 x 2 = 408

408 is our third number.

Now we add the three stamp numbers together to get the total:

102 + 204 + 408 = 714

There are 714 total stamps.

Step-by-step explanation:

if y varies directly as x and y= 6 when x= 10 find x when y=18

Answers

First, you plug in the first set of numbers into the direct variation equation (y=kx). This will be 6 = k(10). Then, you solve for the variable k. Divide 6 by 10 to get k alone on the right side, and k equals 3/5. Then, you plug in y and k to find the new x number. This would be 18 = 3/5(x). Multiply both sides by the reciprocal of 3/5 to get x alone on the right side. This would make x = 30. If y = 18 and the variables vary directly, x would be equal to 30. Hope you have a great day!

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 5y is an equation.

2x + 4 + 9 is an equation.

We have

if y varies directly as x.

This can be written as,

y ∝ x

y = kx _____(1)

From (1),

y = 6 when x= 10

6 = 10k

k = 6/10

k = 0.6

Now,

y = 0.6x

when y = 18,

18 = 0.6x

Divide both sides by 0.6.

x = 18/0.6

x = 180/6

x = 30

Thus,

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles

Answers

Answer:

       First:  30°

 Second:   67°

      Third:  83°

Step-by-step explanation:

        First:   x

  Second:   y

      Third:   z = y + 16

Constraints:

   x + y + z  = 180

   y + z = 5x                  ===>    y = 5x - z

   

Substitution to find first angle x:

   x + y + z  = 180

   x + (5x - z) + z  = 180

   x + 5x - z + z = 180

   6x = 180

    x = 30

Substitution to find second angle y:

   y = 5x - z

   y = 5(30) - z

   y = 150 - z

   y = 150 - (y + 16)

   y = 150 - y - 16

   y = 134 - y

   2y = 134

     y = 67

Substitution to find third angle z:

  z = y + 16

  z = (67) + 16

  z = 83

Answer:

x=30 y=67 z=83

Step-by-step explanation:

The solution is therefore (30,67,83).


If y varies directly as the cube of x, and y=
54 when x = 3, find y when x= 5.​

Answers

Answer:

250

Step-by-step explanation:

From the question given above,

y varies directly as the cube of x. This can be written as

y ∝ x³

y = Kx³

Next, we shall determine the value of the constant (K) as follow:

y = 54

x = 3

K =?

y = Kx³

54 = K × 3³

54 = K × 27

Divide both side by 27

K = 54/72

K = 2

Finally, we shall determine the value of y when x is 5.​ This can be obtained as follow:

x = 5

K = 2

y =?

y = Kx³

y = 2 × 5³

y = 2 × 125

y = 250

Therefore, the value of y is 250

The probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.94.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that the statistics class has 50 students and among those students, 42 are business majors, and 8 like grilled cheese. Of the business majors, 3 like grilled cheese.

The probability will be calculated as:-

P(AUB) = P(A) + P(B) - P(A[tex]\cap[/tex]B)

[tex]P(AUB)=\dfrac{42}{50}+\dfrac{8}{50}-\dfrac{3}{50}[/tex]

[tex]P(AUB) = \dfrac{50-3}{50}[/tex]

[tex]P(AUB)=\dfrac{47}{50}[/tex]

P(AUB) = 0.94

Therefore the probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.94.

The dimensions of a box are 3 cm × 5 cm × 7 cm. The width, length, and height of the box must be increased by the same amount x in order for the box to have a volume of 693 cm cubed. Determine the value of x that will produce a box with a volume of 693 cm3

Answers

Answer:

its 6.6 (I think???)

Step-by-step explanation:

the volume of that box is 105 and 105 x 6.6 is 693. please forgive me if I'm wrong i havent learned this yet.

The dimensions of the new box are 7 cm, 9 cm, and 11 cm.

How to solve

The original volume of the box is 357 = 105 cm3. After the dimensions are increased by x, the new volume is (3+x)(5+x)(7+x) = 693 cm3.

Expanding the product gives [tex]x^3+15x^2+71x-588 = 0.[/tex]

This cubic equation can be solved for x, and the only real solution is x = 4.

Therefore, the value of x that will produce a box with a volume of 693 cm3 is 4. This means that the dimensions of the new box are 7 cm, 9 cm, and 11 cm.
