The students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least
$600 to go on the trip. They have already raised $61. They make $14 for every car they wash.
The students want to know how many cars they need to wash to go on the trip.
Let c be the number of
cars the students wash. Write an inequality that represents the situation.
Answer:
14c + 61 is greater than or equal to (put the greater than symbol with the line underneath there) 600
The inequality for raising the money will be written as 14c + 61 > 600.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than the relation between variables and the numbers.
Given that the students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least $600 to go on the trip. They have already raised $61. They make $14 for every car they wash.

In a lab, 700 cells are present at the beginning of an experiment. During the first 7 hours,
the number of cells increased by 12% each hour.
Estimate the time when the number of cells is 1735.
Round answer to nearest whole hour.
Answer:
2 hours
Step-by-step explanation:
1=700
x=1735
1735=700x
1735/700
x=2.47
Answer:
Step-by-step explanation:
This is an exponential equation of the form, A=ar^t, where a is the initial amount and r is the common ratio or rate of growth and t is time. In this case.
A=700(1.12)^t and we want to find when A=1735
1735=700(1.12)^t
1735/700=1.12^t
ln(1735/700)=t(ln(1.12))
t=(ln(1735/700))/(ln(1.12))
t=8 hours

A rectangular garden has an area of 60 squared feet. The garden is 4 feet longer than it is wide. Which equation can be used to determine the length and width of the garden?
Answer: See explanation
Step-by-step explanation:
Let the width be x
Then, the length will be x+4
Area = Length × Width
Therefore,
x × (x+4) = 60
x² + 4x = 60
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0
x = 6
The width is 6feet
Length = 6+4 = 10 feet
Factor the following: 7k^2+3k-10
Step-by-step explanation:
7k² + 3k - 10
= 7k² + ( 10 - 7 ) k - 10
= 7k² + 10k - 7k - 10
= k( 7k + 10 ) - 1( 7k + 10)
= ( 7k + 10) ( k - 1)
Hope it will help :)
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem to determine the roots
k = 1,-10/7
7k^2+3k-10 = 7(k-1)(k+10/7) = (k-1)(7k+10)
