Answer:

Jay could be thinking of 11  

Step-by-step explanation:

Prime numbers are the numbers that have two factors only, 1 and itself as

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................

All prime numbers can divide by 1 and itself only

∵ A number is a prime number

∵ The sum of its digits is 1 more a square number

∴ The sum of its digits = 1 + x, where x is a square number

→ We will start with the first prime number of 2-digits

∵ 11 is a prime number

∵ The sum of its digits = 1 + 1 = 2

→ Substitute it in the equation above to find x

∴ 2 = 1 + x

→ Subtract 1 from both sides

∵ 2 - 1 = 1 - 1 + x

∴ 1 = x

∵ 1 is the square of 1

∴ Jay could be thinking of 11  

You can check some of the other prime numbers to find another number

Answer: 1,120 frogs

Step-by-step explanation:

If 12 out of every 180 frogs in the population have spots on their backs, the number that do not are;

= 180 - 12

= 168 frogs

168 frogs out of every 180 do not have spots. Out of 1,200 that would be;

= 168/180 * 1,200

= 1,120 frogs

Answer:

2160 degrees

Step-by-step explanation:

The general equation to find the sum of interior angles in a polygon is;

[tex](n - 2) * 180[/tex]

Where "n" is the sides of the polygon.

Substitute in 14 for "n"

( 14 - 2 ) * 180

Solve;

( 14 - 2 ) * 180

12 * 180

2160

Answer:  [tex]385cm^{2}[/tex]

Step-by-step explanation:

given data:

AB= 10 cm.

BC = 22 cm.

volume of a cylinder V = [tex]\pi r^{2} h[/tex]

h = 10.

solution

base of the circumference = 22cm

circumference of a circle = [tex]2\pi r[/tex]

r = radius is unknown.

[tex]2\pi r = 22[/tex] .........................eq1

where [tex]\pi = \frac{22}{7}[/tex] insert this into eq1.

[tex]2* \frac{22}{7}* r = 22[/tex]

[tex]\frac{44}{7} r = 22[/tex]

[tex]r = \frac{22}{\frac{44}{7} }[/tex]

[tex]r= 3.5cm[/tex]

next we solve for the volume of the cylinder.

recall   [tex]V = \pi r^{2} h[/tex]

h = 10cm

r = 3.5cm

[tex]V = \frac{22}{7} * (3.5)^{2} *10[/tex]

[tex]V = 385cm^{2}[/tex]

Answer:

Step-by-step explanation:

Answer:

The producer wrote 20 songs

The Singer wrote 34 songs

Step-by-step explanation:

Let

Number of songs the producer wrote = x

Number of songs the singer wrote = 2x - 6

Total songs written by singer and the producer = 54

54 = x + (2x - 6)

54 = x + 2x - 6

54 + 6 = 3x

60 = 3x

Divide both sides by 3

x = 60/3

= 20

x = 20 songs

Number of songs the producer wrote = x = 20 songs

Number of songs the singer wrote = 2x - 6

= 2(20) - 6

= 40 - 6

= 34 songs

The producer wrote 20 songs

The Singer wrote 34 songs

Answer:

First = 49/4

Second = 539

Step-by-step explanation:

The dot product is 539, and the scalar projection of a onto b is 49/4

Vector is a quantity that has both magnitude and direction.

The scalar projection of a onto b is given by

[tex]\dfrac {a.b}{|b|}[/tex]

a.b = |a| |b| cos[tex]\rm \theta[/tex]

a.b = 21 *44 *(7/12)

a.b = 539

The dot product of a and b is 539.

The scalar projection is

= 539 / 44

= 49/4

Therefore, the dot product is 539, and the scalar projection of a onto b is 49/4.
