Answer:

1) C=2355    2) C=1570   3) C=157    4) C=40.82

Step-by-step explanation:

We use formula to find the Circumference of circle is :

i) C=(PI)d       ii) C=2(PI)r

1. d=750 m

C=(PI)d = (3.14)(750)=2355

2. d=500 kg

C=(PI)d=(3.14)(500)=1570

3. r=25 cm

C=2(PI)r

=2(3.14)25=157

4. r=6.5 m

C=2(PI)r

=2(3.14)(6.5)

=40.82

Identify the prime numbers in the following list 5 7 12 11
Elis [28]

Answer:

<h2>5, 7, 11</h2>

Step-by-step explanation:

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.

A prime number has only two divisors: 1 and itself.

Therefore, the prime numbers are:

5, 7 and 11.

12 is not a prime because 12 = 2 × 6 = 3 × 4.

12 has six divisors: 1, 2, 3, 4, 6 and 12.

Two thirds equals 18 over x plus 5
Wewaii [24]
Problem: 2/3= 18/(x+5)

First, I would multiply the (x+5) over

Making it 2/3(x+5)=18

Second, I would Divide by 2/3 (which is the same as multiplying by the reciprocal 3/2)

which shows up like this now (x+5)=18*3/2

third I would subtract the 5 over

which will give you your answer
