-6-6=-12

Answer= -12

Step-by-step explanation:

Answer:

Factorise:

3a(b+c)-4d(b+c)

Last one.

Further on:

(3a-4d)(b+c)

The factor 3ab + 3ac – 4db – 4dc can be grouped as

a(3b + 3c) - d(4b + 4c).

We can break large polynomials into groups that transmit a common factor. This allows us to factor each separate group, then mix like terms. This exists named factoring by grouping.

Given: 3ab + 3ac - 4db - 4dc.

Expanding the equation a(3b + 3c):  3ab + 3 a c

=3 a b+3 a c-d(4 b+4 c)

Expanding the equation -d(4 b+4 c): -4bd - 4cd

a(3b + 3c) - d(4b + 4c) = 3ab + 3ac - 4bd - 4cd

Therefore, the correct answer is option b) a(3b + 3c) - d(4b + 4c).

Length of the hypotenuse - 10

Step-by-step explanation:

To find the hypotenuse, we need to use the Pythagorean theorem.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = c^2

c^2 = 100

c = 10

Answer:

x = 9.75

Step-by-step explanation:

We know that Triangle ABC and DEF are congruent, therefore;

[tex]\frac{CB}{FE} = \frac{AB}{DE}[/tex]

[tex]\frac{12}{9 }=\frac{13}{x}[/tex]

=> 12*x = 9*13

=> 12x = 117

=> x = 117 / 12

=> x = 9.75

The probability that the winning ticket belongs to Neil is 5%.

It is a branch of mathematics that deals with the occurrence of a random event.

There are a total of 2,000 tickets, and Neil and his 9 friends bought 10 tickets each, so they bought a total of 100 tickets (10 tickets/person x 10 people = 100 tickets).

The probability of Neil's group winning the car is equal to the number of tickets they bought divided by the total number of tickets sold:

Probability = Number of tickets bought by Neil's group / Total number of tickets sold

Probability = 100 / 2000

Probability = 0.05 or 5%

Therefore, the probability that the winning ticket belongs to Neil is 5%.

=======================================================

Explanation:

There are A = 13 hearts and B = 4 copies of "7"

The count A+B = 13+4 = 17 may seem like it's the count of hearts or "7" cards, but we're double counting the 7 of hearts. So the true count is actually 17-1 = 16

There are 16 cards we want (either a heart or a "7") out of 52 total. Therefore, the probability is 16/52 = (4*4)/(4*13) = 4/13

Answer:

79.4%

Step-by-step explanation:

the volume of a cylinder is as for any other regular 3D object

base area × height

the base area is for a cylinder a circle.

so, it is

pi×r² × height

the radius (r) is always half of the diameter.

so, volume of cylinder A is

Va = pi×(10/2)² × 8 = pi×25 × 8 = 200pi ft³

the volume of cylinder B is

Vb = pi×(12/2)² × 7 = pi×36 × 7 = 252pi ft³

therefore, in a volume of 252pi ft³ we have 200pi ft³ filled with water.

252pi = 100% filling

1% = 100%/100 = 252pi/100 = 2.52pi

how many % are 200pi ?

as many as times 1% fit into 200pi :

200pi/2.52pi = 200/2.52 = 79.36507937... ≈ 79.4%

Explanation:

Draw a horizontal line to cut the figure into a rectangle on top and a triangle down below.

The rectangle has length and width of 6 and 4 (horizontal and vertical components respectively). The area of this rectangle is 6*4 = 24 square units.

The triangle has a base of 6 and a height of 4. The base and height of any triangle are always perpendicular.

The area of the triangle is base*height/2 = 6*4/2 = 24/2 = 12 square units. If you were to cut out half of the triangle and rearrange things, you'll find that a rectangle can be formed. This rectangle is half in area that of the first rectangle we found. This is why we divide by 2 when finding the area of the triangle.

Once you know the two sub-areas, we add them up to get the overall area: 24+12 = 36 square units.
