Answer:
10.5 Inches of snow after 6 hours
Step-by-step explanation:
First you would divide
7/4=1.75
Then you would multiply by 6
1.75*6=10.5
10.5 inches of snow would be the total
Hope this helped! :D
The amount of snowfall in 6 hours, if the amount of snowfall is directly proportional to the time, is 10.5 inches.
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.
Given:
In a winter storm, the amount of snowfall is directly proportional to the time,
After 4 hours, a total of 7 inches of snow had fallen,
Calculate the amount of snowfall in one hour as shown below,
amount of snowfall in one hour = 7 / 4
Calculate the amount of snowfall that occurs in 6 hours,
Amount of snowfall in 6 hours = 7 / 4 × 6
Amount of snowfall in 6 hours = 10.5 inches

What pair of points have a slope of -3/5
Answer:
(5,0) and (0,3) have a slope of -3/5
Step-by-step explanation:
Here, we want to state a pair of points that have a slope of -3/5
Mathematically, we can have the slope of a straight line calculated as;
m = y2-y1/(x2-x1)
This could give points like (5,0) and (0,3)

Given: g(x) = Vx – 4 and h(x) = 2x – 8.
What is g(h(10))?
Answer:
g(h(10)) = 43
Step-by-step explanation:
Given: g(x) = 4x – 4 and h(x) = 2x – 8.
We are to find g(h(10))
First we need to get g(h(x))
g(h(x)) = g(2x-8)
Replace x in g(x) with 2x-8 as shown:
g(2x-8) = 4(2x-8)-4
g(2x-8)= 8x-32-5
g(2x-8) = 8x-37
Hence g(h(x)) = 8x-37
g(h(10)) = 8(10)-37
g(h(10)) = 80-37
g(h(10)) = 43
Hence g(h(10)) is 43

The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3. Find the distance of PQ.
Answer:
5 units
Step-by-step explanation:
Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are
P (4 , 0) and Q(0 , 3)
The formula to calculate distance between two points
[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]
IMPORTANT!
As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.

"A number x increased by 6, and then doubled."
A)
2x + 6
B
B)
2x - 6
2(x + 6)
D)
246 - x)
Answer:
(X + 6 ) ×2
It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)
The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.
To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:
Step 1:
Let the number be x.
Increase the number x by 6:
x + 6.
Step 2 :
Double the result by multiply the expression:
(x + 6)2,
Remove brackets by BODMASS gives:
2* x + 2 *6
On multiplying gives:
2x+12
ON taking common factors 2 gives:
2(x+6)
Therefore, the correct expression is 2(x + 6).
Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
