To find the first five multiples of ten, we can multiply 10 by the first five whole numbers.

0 × 10 = 0

1 × 10 = 10

2 × 10 = 20

3 × 10 = 30

4 × 10 = 40

Therefore, the first 5 multiples of 9 are 0, 10, 20, 30, 40.

The multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, amd so on. Each number is 10 more than the previous number.

The sum of 2 numbers is 48 and their difference is 24

Artemon [7]

Answer:

The numbers are 12 and 36

Step-by-step explanation:

x + y = 48

x - y = 24

Add y to both sides of the equation

x = 24 + y

Substitute new value for x into first equation

24 + y + y = 48

Add y's together

24 + 2y = 48

Subtract 24 from both sides of the equation

2y = 24

Divide both sides of the equation by 2

y = 12

48 - 12 = 36

The numbers are 12 and 36

Hope this helps :)

Find the midpoint of a line segment with given endpoints (4,-5) and (-6,3)

Mashcka [7]

The equation for the midpoint of a line segment is $( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$ . Thus, the midpoint of this segment is $(\frac{4 + (-6)}{2}, \frac{-5 + 3}{2}) = \boxed{(-1, -1)}$ .

If 3,000 bacteria, with a growth constant (k) of 2.8 per hour, are present at the beginning of an experiment, in how many hours

Ivenika [448]

Given:

Initial number of bacteria = 3000

With a growth constant (k) of 2.8 per hour.

To find:

The number of hours it will take to be 15,000 bacteria.

Solution:

Let P(t) be the number of bacteria after t number of hours.

The exponential growth model (continuously) is:

$P(t)=P_0e^{kt}$

Where, $P_0$ is the initial value, k is the growth constant and t is the number of years.

Putting $P(t)=15000,P_0=3000, k=2.8$ in the above formula, we get

$15000=3000e^{2.8t}$

$\dfrac{15000}{3000}=e^{2.8t}$

$5=e^{2.8t}$

Taking ln on both sides, we get

$\ln 5=\ln e^{2.8t}$

$1.609438=2.8t$ $[\because \ln e^x=x]$

$\dfrac{1.609438}{2.8}=t$

$0.574799=t$

$t\approx 0.575$

Therefore, the number of bacteria will be 15,000 after 0.575 hours.

Compare 2x+8>18 and 2x+8 greaterthan or equal to 18

Sergio039 [100]

2x + 8 > 18 2x+ 8 ≥ 18
2x > 18 -8     2x ≥ 18 - 8
2x > 10    2x ≥ 10
x > 10/2 x ≥ 10/2
x>5 x ≥ 5

   The answer that combines both inequality is x ≥ 5
