Hello,
Volume of the square pyramid=
1/3×B×h where B represent Base and h represent height

Now, substitute the information that we had from this problem into the formula.
47.25=1/3×B×7
Times 3 from both side
141.75=7B
Divide B from both side
B=20.25 square inches
B=s^2
Square root it to get
s=4.5 inches. As a result, the side length of square base is 4.5 inches. Hope it help!

A phone cost 199$ and is on sale for 25% off. What is the sale price?
andrey2020 [161]

Answer:

<em>See below.</em>

Step-by-step explanation:

Divide the percentage by 100 to turn it into decimal form.

\frac{25}{100}=.25

Then, multiply the percentage by the original amount.

199*.25=49.75

Last, subtract that from the original price.

199-49.75=149.25

<em>Answer: </em>149.25

Can you guys give me a serious answer please?
grin007 [14]

Answer:

800 bacteria

Step-by-step explanation:

Answer of this question depend upon number of hours at the end of day

Let Take Full Day of 24 hrs

Colby bacteria will doubled 12 times ( doubled once in 2hrs => 24/2 = 12)

Colby bacteria at end of day = 50 * 2¹²

Jaquan bacteria will doubled 8 times ( doubled once in 3hrs => 24/3 = 8)

Let say Jaquan bacteria at start  of Day = J

Jaquan bacteria at end of day = J * 2⁸

Equating Both

J * 2⁸ = 50 * 2¹²

=> J = 50 * 2⁴

=> J = 50 * 16

=> J = 800

Jaquan will start  with 800 Bacteria
