Suzi starts her hike at 240 feet below sea level. When she reaches the end of the hike, she is still below sea
level at - 143 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the
hike?
Answer:
383ft
Step-by-step explanation:
Given parameters:
Elevation = 240ft at the start
Elevation at the end = -143ft
Unknown:
Change in elevation:
Solution:
The change in elevation is the difference between the two hiking milestone;
change in elevation = Elevation at the start - Elevation at the end
= 240ft - (-)143ft
= 240 + 143
= 383ft
BRAINLIEST ANSWER!!
During the summer, you work 30 hours per week at the gas station and earn $8.75 per hour. You also work as a landscaper for $11 per hour and can work as many hours as you want. You want to earn a total of $400 per week. How many hours, t, must you work as a landscaper?
Identify an equation that can be used to answer the question.
A) 30t=400-8.75(11)
B) 8.75+11+400=30+t
C) 8.75t+11t=400
D) 30(8.75)+11t=400
Solve the equation to find the number of hours you must work as a landscaper.
You must work ___ hours as a landscaper.
Answer:
1. 30(8.75) + 11t = 400
2. 12.5 hours
Step-by-step explanation:
1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.
30 hours and $8.75 an hour would be equivalent to 30(8.75)
We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t
Finally, you want to earn a total of $400 a week, which means the sum equals 400
30(8.75) + 11t = 400
2. 30(8.75) = 262.5
400 - 262.5 = 137.5
137.5 / 11 = 12.5
2x/3+x/2=5/6
Please solve for x as a fraction!
Answer:
the value of x is 5/7 which is in fraction
Answer: x = 5/7
Step-by-step explanation: 2x/3 + x/2 =5/6
To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.
for 2x/3 6÷3=2 2×2x=4x so that becomes 4x/6
for x/2 6÷2=3 3× (invisible) 1 = 3x, so that becomes 3x/6
combine 4x/6 + 3x/6 = 7x/6
Back to the original equation, substituting the calculated term:
7x/6 = 5/6 Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"
7x = 5 . Divide both sides by 7 to solve for x 7x/7 = 5/7
x = 5/7

The length of cell A is 8x10 to the power of negavtive 6 m. The length of cell B is0.0000004 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
Answer:
Ratio of length of cell A to cell B is 20 : 1
Step-by-step explanation:
Length of cell A = [tex]8\times 10^{-6}[/tex] m
Length of cell B = 0.0000004 m
Convert the length of cell B into scientific notation.
Length of cell B = [tex]4.0\times 10^{-7}[/tex]
Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]
= [tex]2\times 10^{7-6}[/tex]
= 20
Therefore, ratio of length of cell A to cell B is 20 : 1

Write an equation for the line that is parallel to the given line and passes through the given point . Write the equation of the line in y=mx+b form
y=5x-7;(2,-2)
A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).
Point-slope is:
y-y₁=m(x-x₁)
Plug in our known values:
y-(-2)=5(x-(2))
Distribute and set it equal to y:
y+2=5x-10
y=5x-12

what is the solution of the inequality 4+5x<-19
Answer: x>−3
Step-by-step explanation:
Pull out like factors :
-15 - 5x = -5 • (x + 3)
Divide both sides by -5
Remember to flip the inequality sign
Subtract 3 from both sides

Select all of the zeros of the function f(x)=(3x−4)(x+2).
(I NEED TO SHOW MY WORK SO PLEASE SHOW HOW YOU GOT THE ANWSER)
Select all that apply:
4
2
43
− 43
− 2
− 4
Answer:
The zeros of the function are x = 4/3 or x = -2
Step-by-step explanation:
To find the zeros of the function, we set f(x) to zero
Thus;
(3x-4)(x + 2) = 0
3x - 4 = 0
or x + 2 = 0
3x = 4 or x = -2
x = 4/3 or x = -2

Answer:
D
Step-by-step explanation:
The constant of proportionality is 8 as seen by the equation:
y = 8x
8 will constantly be multiplied by x (the number of dollars earned) to solve for y (number of tickets sold)
The number 8 will not change
Therefore, 8 is the constant ot proportionality

7x-130=110+9x. show with steps
Answer:
x=-120
Step-by-step explanation:
7x-130=110+9x
add 130 to both sides of the equation
7x-130+130=110+9x+130
Simplify
7x=9x+240
Subtract 9x from both sides
7x-9x=9x+240-9x
Simplify
-2x=240
divide both sides by -2
-2/-2=240/-2
simplify
x=-120

Answer:
3x(2+n)+[7+n]
Step-by-step explanation:
The answer is kind of self-explanatory, but think of it this way. If n=5, then the equation would be 3x(2+5)+[7+5]. First we would solve 2+5 which is 7. Then we would do 7+5 which is 12. We are now left with 3x7+5.
