Answer:
x=78.2
Step-by-step explanation:
Answer:
x = 8.94 inches
Step-by-step explanation:
Since it is already given that the area of the painting is 400 in² and the fact that area is length times width, we can make an equation and solve for x:
A=LW
400=(4x+9)(x)
400=4x^2+9x
0=4x^2+9x-400
Use the quadratic formula:
x=[-9±√(9²-4(4)(-400))]/2(4)
x=[-9±√(81+6400)]/8
x=[-9±√(6481)]/8
x = [-9+√(6481)]/8 = 8.938082281 = 8.94
x = [-9-√(6481)]/8 = -11.18808228 = -11.19
Since distance can only be positive, we will choose 8.94 as the correct solution. Therefore, x = 8.94 inches is the correct answer.

A math teacher said that 18 out of 25 students passed the test what percent did not pass the test
Answers
Answer:
28%
Step-by-step explanation:
18/25=.72 ->72% passed the test, so then we take 100 and subtract 72 from it which leaves us with 28% that did not pass the test
Answer:
28% of students did not pass.
Step-by-step explanation:
18/25 = 72/100
72% passed.
So, if 18/25 students passed, (72%) then 7/25 students did not pass (28%)

Answer:
x=-7
Step-by-step explanation:
-2(x−3)+4x=−(−x+1)
Step 1: Simplify both sides of the equation.
−2(x−3)+4x=−(−x+1)
−2)(x)+(−2)(−3)+4x=x+−1(Distribute)
−2x+6+4x=x+−1
(−2x+4x)+(6)=x−1(Combine Like Terms)
2x+6=x−1
2x+6=x−1
Step 2: Subtract x from both sides.
2x+6−x=x−1−x
x+6=−1
Step 3: Subtract 6 from both sides.
x+6−6=−1−6
x=-7
if I have a 53 in class what grade do I need to get in a test to get a 90
Answers
Answer:
you would have to make 100s on at least 5 tests or assignments
Step-by-step explanation:
Answer:
It depends.
Step-by-step explanation:
Basically, your grade is a result of the average score on all of your assignments and even attendance. Average is all scores added together, divided by the number of scores. Also, depending on the teacher, some scores weigh more, meaning a test counts for more than a worksheet does.
Also, even if you get a 100 on your test, you'll unlikely get a 90. :(
)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answers
Answer:
Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60
Initial value = $750
Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

The Salinas brothers, Juan and Carlos, have collected pledges for a bike rally they plan to have to raise money for their boy scout troop. Carlos's pledges total $11.50/mi and Juan's pledges total $9.75/mi. Carlos can peddle 10 mi/hr and Juan can peddle 12 mi/hr. If they plan to start and stop at the same time, how many hours will they have to bike if they want to raise at least $1000 together?
Answers
Answer:
5 hours
Step-by-step explanation:
Given that :
Juan:
Rate = 12mi/hr
$9.75/mi
Carlos :
Rate = 10mi/hr
$11.50/mi
To raise atleast $1000 altogether :
Let number of hours = h
Distance = rate * time
[(12*h) * 9.75] + [(10*h) * 11.50] ≥ 1000
[117h + 105h] ≥ 1000
222h ≥ 1000
h ≥ 1000/222
h ≥ 4.504
To earn atleast $1000 altogether, they must work for atleast 5 hours (nearest whole number).

Answers
Answer:
D) {-2, 1, 2, 5}
Step-by-step explanation:
The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.
In this case, the output refers to the y-values of the function.
Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.
Thus, choice D is correct.
