What is the GFC for 80 and 96

Answers

Answer:

16

Step-by-step explanation:

Greatest common factor (GCF) of 80 and 96 is 16. We will now calculate the prime factors of 80 and 96, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 80 and 96.

16 is the greatest common factor !!

A scientist is studying bacteria in a dish and discovered they grow and can 3 be tracked using the formula: 5*(1.50)^x +10, where x represents every hour. How many bacteria will there be after 9 hours? (Round Your Answer To The Nearest Whole Number)
A) 38
B) 48
C) 192
D) 202​

Answers

Answer:

D

Step-by-step explanation:

if x= number of hours replace the x by 9

so you have 5×(1.50)^9+10=

5×(192.21)+10 = 202.21 so 202 will be nearest whole number

D) 202

Steps:

Formula 5*(1.50)^x + 10

1. Plug in 9 for x
5*(1.50)^9 +10

2. Solve exponents (38.443359375) and round to nearest hundredth
5*38.44+10

3. Multiply
192.2 +10

4. Add
202.2

5. Round to nearest whole number
202

Step-by-step explanation:

We can start with the fact that [tex]d = st[/tex], where d is the distance traveled at a speed of s for some amount of time t. If we want to solve for t, we can divide both sides of the equation by s to get the form [tex]t=d/s[/tex]. Plugging in the values of d = 12.5 m and s = 5 m/min gives us [tex]t=12.5/5=2.5[/tex] min.

Determine whether a triangle with the given vertices is a scalene, isosceles, or equilateral triangle. Check all that apply.

Answers

9514 1404 393

Answer:

  (a) isosceles

  (b), (c) scalene

Step-by-step explanation:

The lengths of the sides can be found from the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.

We find triangle (a) has two sides the same length, so it is isosceles.

The other two triangles have three different side lengths, so they are scalene.

Find the AROC for 6x-9 for the interval x=0 to x=2

Answer:

AROC =6

Step-by-step explanation:

Let f(x)=6x-9

When x=2

f(2) =6(2)-9 = 3

When x=0

f(0)=6(0)-9 =-9

So, average rate of change AROC=[tex]\frac{3-(-9)}{2-0} =\frac{12}{2}[/tex] =6

So, AROC=6
