38.25 because both numbers are negative and a negative number times a negative number is a positive number.
Step-by-step explanation:
When you multiply just forget about them being negative for a little, and move the decimal to the right until you have a integer (a whole number not a fraction/decimal). Than multiply it how you normally multiply, now that you have 3825 you have to add the number of spots you moved the decimals which is two one for the top one for the bottom, which is 2 places and then move the decimal 2 places to the left in our number which will make it 38.25. Both numbers are negative and a negative number times a negative number is a positive number. So yeah. :D

Find the volume of a hemisphere with a radius of 8. Round to the nearest tenth.
Answers
Answer:
V(hemisphere) = 1072.3in^3
Step-by-step explanation:
To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.
The volume of a sphere is:
[tex]V(sphere) = \frac{4}{3} \pi r^3[/tex]
Let's plug in the radium of 8 into the equation and solve:
[tex]V(sphere) = \frac{4}{3} \pi (8)^3\\V(sphere) = \frac{4}{3}\pi 512 \\V(sphere) = 2144.660585[/tex]
Now, divide it by 2
V(sphere) = (2144.660585)/2
V(hemisphere) = 1072.3in^3
I hope this helps!!

Answer:
the answer is V(hemisphere) = 1072.3in^3

A construction crew is extending a highway sound barrier that is 13 miles long. the crew builds 1/2 of a mile per week. Write an equation the represents the length Y (in miles) of the barrier after X weeks.
Answers
Answer:
y= 1/2x + 13
because the barrier is already 13 miles long, and they're adding 1/2 miles every week
The equation the represents the length Y (in miles) of the barrier after X weeks is y = (1/2)x + 13
A linear equation is in the form:
y = mx + b;
where m is the slope, b is the y intercept and y, x are variables.
Let y represent the length of the barrier after x weeks.
Since the crew builds 1/2 of a mile per week hence m = 1/2, Also the barrier is 13 miles long, hence b = 13, hence:
y = (1/2)x + 13
The equation the represents the length Y (in miles) of the barrier after X weeks is y = (1/2)x + 13

The test tube is cold best describes what is felt.
Option A is the correct answer.
What is a chemical reaction?A chemical reaction is a process that leads to the transformation of one set of chemical substances into another.
In other words, it is the process of breaking and forming chemical bonds between atoms to create new compounds with different properties than the original substances.
We have,
An endothermic reaction is a type of chemical reaction that absorbs heat from the surrounding environment, resulting in a decrease in temperature.
In this case,
The chemical reaction that occurred in the test tube absorbed heat from the surroundings, including the air and the test tube itself.
As a result, the temperature of the test tube decreased, making it feel cold to the touch.
Thus,

Answer:
s=3
hope u have a great day
Answer:
s = 3
Step-by-step explanation:
STEPS FOR SOLVING LINEAR EQUATION
6.49s+8.32=27.79
Subtract 8.32 from both sides.
6.49s=27.79−8.32
Subtract 8.32 from 27.79 to get 19.47.
6.49s=19.47
Divide both sides by 6.49.
s=
6.49
19.47
Expand
6.49

by multiplying both numerator and the denominator by 100.

Answer:
x=−6/5Step-by-step explanation:
[tex]\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\[/tex]
Simplify both sides of the equation:[tex]\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3[/tex]
[tex]\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3[/tex]
[tex]( 1/3x + 1/2x ) + ( −2+6 ) = 3[/tex] (Combine Like Terms)[tex]5/6 x + 4 = 3[/tex]
Subtract 4 from both sides:[tex]5/6x + 4−4= 3−4[/tex]
[tex]5/6x = −1[/tex]
Multiply both sides by 6/5:[tex](6/5) * (5/6x) = (6/5) * (−1)[/tex]
