2 answers:

5 0

A. Prime numbers have only 2 factors 1 and itself

B. Composite numbers have at least one divisor other than itself

C. 1 is neither prime nor composite because the only factor is 1 prime numbers have two factors another factor and its self not two of the same factors same with the composite what happens is that 1 should have more factors than just itself as of what composite is about! So 1 is neither prime nor composite

Really hope it helps!!

Calculate the shaded area

Anton [14]

----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the semicircle = 10 ÷ 2 = 5cm

----------------------------------------------------------------
Find Area of the semi circle :
----------------------------------------------------------------
Area of the semi circle = 1/2 πr²
Area of the semi circle = 1/2 x π x (5)²
Area of the semi circle = 12.5π cm²

----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the inner circle = 5 ÷ 2 = 2.5 cm

----------------------------------------------------------------
Find area of inner circle :
----------------------------------------------------------------
Area of the inner circle = πr²
Area of the inner circle = π x (2.5)²
Area of the inner circle = 6.25π

----------------------------------------------------------------
Area of the shaded region :
----------------------------------------------------------------
Area of the shaded region = 12.5π - 6.25π
Area of the shaded region = 6.25π
Area of the shaded region = 19.63 cm²

----------------------------------------------------------------
Answer: Area of the shaded region = 19.63 cm²

Answer:

y = 0.2·0.5^x

Step-by-step explanation:

An exponential function is generally of the form ...

y = a·b^x

where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.

In the given table, y = 0.2 for x = 0, so a = 0.2.

We find that the value for x = 1 is 0.1, so the value of b is ...

b = 0.1/0.2 = 0.5

Then the exponential function is ...

y = 0.2·0.5^x

Devin sent a total of 20 texts and emails on Monday. The number of texts was one less than twice the number of emails. Find the

anyanavicka [17]

Answer:

21 mails

Step-by-step explanation:

Let there are x no of texts and y no of emails.

Condition 1,

x+y = 20 ...(1)

Condition,

x=2y-1 ...(2)

Put the value of x from equation (2) in (1). So,

(2y-1)+y = 20

Taking like terms together,

2y-y=20+1

y=21

So, Devin sent 21 mails,.
