If we had AB: BC: CD, we could easily have solved that problem. In order to combine these ratios, we need to have the same number for BC. We can create this number by finding LCM (Least Common Multiple) for 5 and 3, which is 15. Then, we can write ratios of AB:BC = 6:15 and BC:CD=15:20. Now, we can easily combine these ratios. AB:BC:CD = 6:15:20. Then, 6k+15k+20k = 82 and k=2 cm. And BC = 30 cm

Viktor [21]
To find the volume of all 4 pans, you will use the formula for finding the volume of a rectangular prism and then multiply it by 4 because they are all the same size.

7 in. x 7 in. x 2 in. - 98 cubic inches

98 cubic inches x 4 = 392 cubic inches.

The expression that puts this all together is:

4 (7 x 7 x 2) or 4(98).

Part 7 math work 10th-grade work
Irina-Kira [14]

Answer:

x>11 is the solution to both equations.

Step-by-step explanation:

I apologize for late response I've been busy lately. Anyways here ya go! :

From what I understand it wants us to solve "9x-4>95" so that's what I'll do.

add 4 to each side

9x>99

divide each side by 9

x>11 is the solution to 9x-4>95

For 4x+10>54

subtract 10 from each side

4x>44

divide each side by 4

x>11 is the solution to 4x+10>54

bija089 [108]

As per the given information;

Bacteria triples every month.

Originally, there were 4 bacterial cells.

We are suppose to find how many there will be after 15 months.

Hence we can say , the number of bacteria after n month can be given using the exponential growth function

a_n=4*3^n

So number of bacteria after 15 month will be

a_{15}=4*3^{15}
