A prime number is a number which is only divideable by 1 or the number itself.

The prime numbers between 0 and 25 are:
2
3
5
7
11
13
17
19
23.
This are 9 numbers, so the answer is 9.

Calculate the area of a circle with a diameter of 6cm

7nadin3 [17]

Area of circle = πd²/4, where d = diameter

= π*6*6/4 = 9π ≈ 9 *3.1416 ≈ 28.2744 cm²

Area ≈ 28.27 cm²

Hope this explains it.

What is -8x - 2y= -4 when y equals -5x

PSYCHO15rus [73]

-8x - 2y = -4

When y = -5x
-8x - 2(-5x) = -4
- 8x + 10x = -4
2x = -4
x = -4/2 = -2

The M virus has a diameter of 5 x 10^-7meters, while the P virus measures about 2 x 10^-8meters in diameter. A) is the M virus o

Fynjy0 [20]

Answer:

(A) The M virus is larger than the P virus in diameter

(B) Diameter of virus M is 25 times the diameter of virus P

Step-by-step explanation:

Notice that the values given are in the so called "scientific notation", and which involves in this case negative exponents for the multiplier 10.

So we can write these values in decimal form for easier comparison of which one is he largest one:

Diameter of M virus = $5\,*\,10^{-7}\,m = 0.0000005\,\,m$

Diameter of P virus = $2\,*\,10^{-8}\,m = 0.00000002\,\,m$

Which clearly shows that virus M is larger than virus P in diameter

The quotient between diameters will give us the answer to how many times larger virus' M diameter is:

$\frac{M}{P} =\frac{0.0000005}{0.00000002} \\\frac{M}{P} =25$

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the po

cestrela7 [59]

Answer:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

x = 180/7.5

x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

= 360 ÷ 24

= 15
