Using the Fundamental Counting Theorem, it is found that he has 10 possible options to choose from.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem:

The total number of options is given by:

N = 2 x 5 = 10.

Answer:

Answer depends on the value you put

Step-by-step explanation:

let's say a= 3 and x =4 then,

or 3*4 -w = 3

or 12 - w = 3

or -w = 3- 12

or -w = -9

or w = 9

just put any value in a and x and you will get the answer

Answer:

B. There is only one base for a pyramid.

D. The faces of pyramids are traingles.

E. The faces of prisms are rectangles.

Step-by-step explanation:

The difference between a pyramid and a prism is:

There is only one base for a pyramid.

The faces of pyramids are triangles.

The faces of prisms are rectangles.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The number of vertices is always equal to the number of sides for a prism but not a pyramid.

The faces of pyramids are triangles while the faces of prisms are rectangles.

A prism has two parallel bases and its other faces are rectangles.

A pyramid has a single base and its faces are triangles.

A prism also has the same number of vertices as its number of sides, but this is not true for a pyramid.

Thus,

The difference between a pyramid and a prism is:

There is only one base for a pyramid.

The faces of pyramids are triangles.

The faces of prisms are rectangles.

Answer:

1500 * 0.07 = 105

105 + 1500 = 1605

Step-by-step explanation:

The value of the x of the equation x² + 2x = 24 is negative 5 and negative 1, then the correct option is A.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression equation is given below.

f(x) = x² + 6x + 5

On factorization, we have

     x² + 6x + 5 = 0

x² + 5x + x + 5 = 0

   (x + 5)(x + 1) =0                    

                    x = -1, -5

The value of x is –5 and –1.

Answer:

m∡DHE = 315°

Step-by-step explanation:

Angles around a point always add up to 360°.

⇒ m∡DHE = 360° - m∡ED

                  = 360° - 45°

                  = 315°

Answer:C. 38.14

Step-by-step explanation:

The required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Given that,
The number of hours the employee worked each week for seven consecutive weeks was 38, 37. 5, 38. 25, 35. 75, 39. 5, 39. 5, and 38. 5.

The mean of the values is the ratio of the total sum of values to the number of values.

here,
According to the question,
Mean = Sum of the working hours/number of weeks
Mean = 38 + 37. 5 + 38. 25 + 35. 75 + 39. 5 + 39. 5 + 38. 5 / 7
Mean = 267/7
Mean = 38.14

Thus, the required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Answer:

BC ≈ 18.7

Step-by-step explanation:

using the sine rule in Δ ABC

[tex]\frac{BC}{sinA}[/tex] = [tex]\frac{AC}{sinB}[/tex] ( substitute values )

[tex]\frac{BC}{sin67}[/tex] = [tex]\frac{20}{sin80}[/tex] ( cross- multiply )

BC × sin80° = 20 × sin67° ( divide both sides by sin80° )

BC = [tex]\frac{20sin67}{sin80}[/tex] ≈ 18.7 ( to the nearest tenth )

is given that the number of bacteria doubles every hour.

Therefore, the number of bacteria after every hour will form a G.P.

with first term (a=30) and common ratio (r=2)

∴a

2

=(30)(2)

Therefore, the number of bacteria at the end of 2nd hour will be 480.

Answer:

choose D

Step-by-step explanation:

x/(x²+3x+2) - 1/[(x+2)(x+1)]

x² + 3x + 2 = x² + 2x + x + 2

= x(x + 2) + (x + 2)

= (x + 2)(x + 1)

= x/[(x+2)(x+1)] - 1/[(x+2)(x+1)]

= (x-1)/[(x+2)(x+1)]

= (x-1)/(x²+3x+2)

Measure of an exterior Angle of a triangle is sum of two opposite interior angles of the same triangle ~

that is :

[tex]\qquad \tt \dashrightarrow \: \angle1 = 60 + 30[/tex]

[tex]\qquad \tt \dashrightarrow \: \angle1 = 90 \degree[/tex]

So, D is the correct choice ~

Step-by-step explanation:

As the sum of all angles of triangle is 180°

and we have been given 2 angles i.e 30° and 60°

So, Third angle will be 90°

Angle 1 = 180°-90° (as the value of angle made by a straight line is 180°)

Angle 1 = 90°
