When a volcano erupts, the height of the peak is reduced and the upper portion is removed. The height of a volcano after it erupted was 8,219.5 feet. This was 85% of the volcano's original height. What was the original height?
(answer this and show your work please thank you)
The original height was _answer this_ feet.
please help me with this thank you
Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
we translate word problem to equation.
8219.5 IS 85% of TOTAL
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
8219.5 = 0.85 * Total
Hence, total = [let total be 7]
8219.5 = 0.85 * t
t = 8219.5/0.85 = 9670 feet

Write a linear equation in slope-intercept form to represent the data shown in this table.
Bicycle Rental Costs
Time, x(hours) Total cost, y(dollars)
1 $8
2 $16
3 $24
Show your work.
Answer:
[tex]\displaystyle y=8x[/tex]
Step-by-step explanation:
We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.
So, we will first need to determine the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are two points.
We have three points: (1, 8), (2, 16), and (3, 24).
Let’s pick two. We can use (1, 8) and (2, 16).
So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{8}{1}=8[/tex]
So, our slope is 8.
Now, we can determine the equation using point-slope form:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
We know that the slope is 8, so we will substitute 8 for m.
We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:
[tex]\displaystyle y-8=8(x-1)[/tex]
Solve for y. Distribute the right:
[tex]\displaystyle y-8=8x-8[/tex]
Add 8 to both sides:
[tex]\displaystyle y=8x[/tex]
And we have our equation.
Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.

Bob paid $5.60 for 0.8 lb of fresh peaches. What is the constant of variation?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
y ∝ 7x
y = 7x
Where y is the cost of the fresh peaches and x is the number of pounds.
The constant of variation is 7.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Bob paid $5.60 for 0.8 lb of fresh peaches.
This means,
0.8 lb = 5.60
Divide 0.8 on both sides.
1 lb = 5.60/0.8
1 lb = $7
Now,
y ∝ 7x
y = 7x
Where y is the cost of the fresh peaches and x is the number of pounds.
The constant of variation is 7.
Thus,
y ∝ 7x
y = 7x
Where y is the cost of the fresh peaches and x is the number of pounds.
The constant of variation is 7.

Each pair of points lies on a line with the given slope. Find y.
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

Evaluate the expression for x = 1.7. Enter your answer in the box.
x2 + 3x
Answer:
7.99
Step-by-step explanation:
You have the following expression:
x^2 + 3x
In order to determine the value of the previous expression for x = 1.7, replace this value into the previous expression and simplify:
(1.7)^2 + 3(1.7) = 2.89 + 5.1 = 7.99
Hence, the result is 7.99
At a local bakery, Emily buys 6 cookies for $4.50. Each of the cookies costs the same amount.
Which equation represents the price, P, in dollars of c cookies?
P=c0.75
P=0.75c
P=c6
P=6c
Answer:
I don't know
Step-by-step explanation:
The correct equation to represents the price P in dollars of c cookies will be;
⇒ P = $0.75c
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The cost of 6 cookies = $4.50
Now,
Since, The cost of 6 cookies = $4.50
Hence, The cost of 1 cookies = $4.50/6
= $0.75
So, We can formulate;
The cost of c cookies = $0.75c
Hence, The equation to represents the price P in dollars of c cookies is;
⇒ P = $0.75c
Thus, The correct equation to represents the price P in dollars of c cookies will be;
⇒ P = $0.75c

Carla and George each went hiking.The expressions 4(ℎ + 2) – 2ℎ and 3(2 + ℎ) represent the respective distances Carla and George hiked each day. On what day number h will their distance hiking be the same?
plz help
Answer:
day 2
Step-by-step explanation:
4(h+2)-2 is 2h+8 and 3(2+h) is 3h+6, and if you do guess and check, when you fill h in as 2, both expressions equal 12.
On the 2nd day, their distance hiking is the same.
Given
Carla and George each went hiking.
The expressions [tex]4(h + 2) - 2h[/tex] and 3(2 + h) represent the respective distances Carla and George hiked each day.
Therefore,
On what day number h will their distance hiking be the same?
[tex]\rm 4(h+2)-2h = 3(2+h)\\\\4h+8-2h=6+3h\\\\2h+8=6+3h\\\\3h-2h=8-6\\\\h = 2[/tex]
Substitute the value of h in the equation first;
[tex]= 4(h+2)-2h\\\\= 4(2+2)-2\times 2\\\\=4(4)-4\\\\=16-4\\\\=12[/tex]
Substitute the value of h in the equation second
[tex]\rm =3(2+h)\\\\= 3(2+2)\\\\= 3\times 4\\\\= 12[/tex]

What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.
Rate for cart mart is (32 - 43)/(3 - 2) = - 11.
Car Mart sells 11 cars a day.
Winston's sells 10 cars per day.
Car Mart sells more cars per day.
As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.
As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.
