Answer:

Step-by-step explanation:

Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]

                                           = 360 cm³

2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

   Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

                                                 = [tex]\frac{1}{2}(8)(5)[/tex]

                                                 = 20 cm²

   Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]

                                                             = 80 cm³

5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

    Here, r = radius of the circular base

    h = Height of the cone

    Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]

                                      = [tex]\frac{16\pi }{3}[/tex]

                                      = 16.76 cm³

Por Berta

Para reformar su cocina, Berta compró la semana pasada 2 cajas de baldosas de plaquetas para el suelo y 4 cajas de baldosas para la pared por 200 €.

2x + 4y = 200 ...... Ecuación 1

Hoy

Hoy compré 2 cajas más de plaquetas y otras 2 de tejas por 130 €.

2x + 2y = 130 ..... Ecuación 2

Resolvemos usando el método de Eliminación

2x + 4y = 200 ...... Ecuación 1

2x + 2y = 130 ..... Ecuación 2

Restar la ecuación 2 de 1

2 años = 70

y = 70/2

y = 35 €

Resolviendo para x

2x + 4y = 200 ...... Ecuación 1.

2x + 4 × 35 = 200

2x + 140 = 200

2x = 200 - 140

2x = 60

x = 60/2

x = 30 €

Step-by-step explanation:

Answer:

74 degrees

Step-by-step explanation:

Assuming we have the following

FD = 14

DE = 52

m<F = 90degrees

Required

m<D

DE = hypotenuse

FD = adjacent

Using the SOH CAH TOA identity

Cos m<D = adj/hyp

Cos m<D = 14/52

m<D = arccos(0.2692)

m<D = 74.38

m<D to the nearest degree is 74degrees

Answer:

24 and 42 represent one combination, but 2 permutations. Thus, the number of two-digit numbers that can be made with the digits 2, 4, 6, and 8 is: Therefore, 12 two-digit numbers can be made with the digits 2, 4, 6, and 8.

Step-by-step explanation:

please mark this answer as brainliest, leave a 5-start rating, and give a thanks

The number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

The given digits are 4, 6 and 8.

We know that, P(n, r)= n!/(n-r)!

Here, n=3 and r=2

Now, 3!/(3-2)!

= 3×2

= 6

Using C(n, r)= n!/r!(n-r)!

Now, 3!/2!(3-2)!

= 3

So, 6×3

= 18

Therefore, the number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Step-by-step explanation:

Calculate annual interest amount first:

                annual interest x 9/12=21

                Annual interest =21x12/9

                 annual interest amount=$28

calculate annual interest rate

                1400 x interest rate = annual interest

               $1400 x interest rate = $28

                interest rate =$28/1400

                interest rate=.02 or 2%

Initial co-ordinate of p = ( 2, -2)

Rule for rotation 180° about the origin

(x,y) ----> ( -x , -y )

Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN

* add - to the coordinates *

- ( 2 , -2 )

-1 * 2 = -2

-1 * -2 = 2

we end up with ( -2, 2 )

Hence the answer is B

For this one a rectangle was dilated and we have to find the scale factor and the new width.

We are given the pre image width (3) and length (4) and the new image length (12)

We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )

So scale factor = 12 / 4  or 3

Now to find the new image width

We can do this by multiplying the pre image width (3) by the scale factor (3)

So new image width = 3 * 3

3 * 3 = 9

Hence the width of the enlarged  print is C 9 inches

For this one we need to find x using angle rules

The angles shown are supplementary angles meaning that the sum of the two angles is 180

That being said we can create an equation to solve for x

180 = 64 + 4x + 16

Now we just solve using basic algebra

step 1 combine like terms

64 + 16 = 80

now we have 180 = 4x + 80

step 2 subtract 80 from each side

80 - 80 cancels out

180 - 80 = 100

now we have 100 = 4x

step 3 divide each side by 4

100/4 = 25

4x/4=x

we're left with x = 25

Answer:

The value of x is 15 .

Option (A) is correct.

Step-by-step explanation:

As given

∠1 and ∠2 are complementary.

i.e the sum of ∠1 and ∠2 is 90° .

Thus

∠1 + ∠2 = 90°

x° + (3x+30)° = 90°

x + 3x + 30 = 90

4x = 90-30

4x = 60

x = \frac{60}{4}x=

4

60

x = 15

Therefore the value of x is 15 .

Option (A) is correct.

Answer:

A. x=15

Step-by-step explanation:

To solve this problem, we can combine like terms.

3x + (1)x are like terms.

3x + (1)x = 4x.

Since 3x and (1)x are the only pair of like terms, we are done with this step.

Complementary angles have a sum of 90°.

4x + 30 = 90.

Next, we subtract 30 from 90.

90 - 30 = 60.

Then, we divide 60 from 4.

60 / 4 = 15.

15 is the final answer.

Therefore, the value of x is 15.

The median of the math scores is = 79%.

You can understand more about calculation of median of a set of numbers below.

The total number of sophomores is = 8

The percentage score of each sophomore = 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%.

To calculate the median of the percentage scores, arrange the scores in ascending order and pick the figure in the middle as the median math score.

72, 74, 76, 78, 80, 82, 92, 92

Here the median is two figures 78, and 80 which are located in the middle. The median is =>78 +80/2

= 158/2 = 79%

Therefore, the median of the math scores is = 79%

Answer:

P = 0.075     P = 7.5%

Step-by-step explanation:

We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.

We know for a fact that the probability that the quarterback fails the first attempt is:

p(1) = 0.5

and we know that the probability that the quarterback fails the second attempt after failing the first is:

p(2/1) = 0.15  

Then the probability of failure of both attempts is:

P(2/1) = p(1 and 2) / p(1)

p(1 and 2) = P(1) * P(1/2)

p(1 and 2) = 0.5 * 0.15

and that is

p(1 and 2) = 0.075

Answer:

27 and 18

Step-by-step explanation:

The range is the difference between the largest and smallest numbers

(10)

Given range = 18 and smallest number is 9 then

largest number = 9 + 18 = 27
