Answer:
Sound waves need a medium to travel, but light waves do not.
Step-by-step explanation:
Sound waves need a medium to travel because they cannot travel through a vacuum. This is because sound travels by producing vibration in the molecules of the medium surrounding it and there are virtually no molecules in a vacuum. Light doesn't need a medium through which to travel because the speed of light is experimentally constant.
Solve for g. Show your work!
g+7 4=15
Answer:
g = 12
Step-by-step explanation:
g + 7 - 4 = 15
Combine like terms
g +3 = 15
Subtract 3 from each side to isolate g
g+3-3 = 15-3
g = 12
Answer:
g = -59
Step-by-step explanation:
g + 74 = 15
subtract 74 from both sides
g = -59

a number x divided by 8 is less than -2
Answer: x/ 8 < -2 and x< -16
Step-by-step explanation:
A numer x is divided by 8 is the same as x/ 8 and x/8 has to be the less than -2 so it will be x/8 < -2
x/8 < -2 TO solve the inequality, multiply 8 on both sides to get
x < -16
The solution of expression is,
⇒ x < - 16
We have to given that,
An algebraic expression is,
''a number x divided by 8 is less than -2''
We can write as,
⇒ x / 8 < - 2
Solve for x,
⇒ x/8 < - 2
Multiply by 8;
⇒ x < - 2×8
⇒ x < - 16
Therefore, The solution of expression is,
⇒ x < - 16

Which would be used to solve this equation? Check all that apply.
subtracting 3 from both sides of the equation
multiplying both sides of the equation by 3
dividing both sides of the equation by 3
substituting 4 for p to check the solution
substituting 36 for p to check the solution
Answer:
1 3 4
Step-by-step explanation:
umm i suck at explaining sorry
Answer: Multiplying both sides of the equation by 3
substituting 36 for p to check the solution
Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.
Then you have 3(p/3) = 3(12)
p = 36 simplify
To check this work, you can substitute 36 for p:
36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

Can someone please explain the Slope formula? Don't quite get it. I'm working on edge Physical science grade 8
Answer:
ok is that a question or not but if it is i may be help u
Answer:What About y = mx + b ? You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis.

A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?
Answer:
Each friend bought 3.45 bushels of corn.
Step-by-step explanation:
12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1
