Answer:
7.390
Step-by-step explanation:
Answer:
7.39
Step-by-step explanation:
The hundredths place of 7.393 is the 9.
To round off to the nearest hundredth, drop all decimal place to the right of the hundredths place.

Answer ASAP Which is a y-intercept of the continuous function in the table? (5, 0) (0, 1) (0, 5) (1, 0)
Answer:
(0, 5 )
Step-by-step explanation:
The y- intercept is where the function crosses the y- axis.
This occurs when x = 0 , thus
From the table when x = 0 , f(x) = 5 , thus
y- intercept is (0, 5 )
y- intercept is (0, 5 )

Kendal is waiting at a crosswalk 540 meters away from the library. She begins riding her bike toward the library and then passes the
library at a constant rate of 6 meters/second.
Kendal will be 60 meters away from the library after
seconds and again after
seconds.
Answer
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
Let t represent time in seconds. Kendal is riding at a rate of 6 meters/second, so 6t represents the distance she can travel in t seconds.
The distance to the library is 540 meters. Because Kendal is riding toward the library, subtract 6t from 540 to find the distance between Kendal and the library before she passes it:
540 − 6t.
Kendal will be 60 meters away from the library twice, once as she approaches it and again after she passes it. The absolute value of the difference 540 − 6t represents Kendal's distance from the library. To find the time after which Kendal will be 60 meters away from the library, form an absolute value equation:
|540 − 6t| = 60.
Solve an absolute value equation by writing it as two separate linear equations and solving each one:
540 − 6t = -60 540 − 6t = 60
-6t = -600 -6t = -480
t = 100 t = 80
Let t represent time in seconds. Kendal is riding at a rate of 6 meters/second, so 6t represents the distance she can travel in t seconds.
The distance to the library is 540 meters. Because Kendal is riding toward the library, subtract 6t from 540 to find the distance between Kendal and the library before she passes it:

The answer is 80
What is Algebra?algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. it involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
Given:
Kendal is riding at a rate of 6 meters/second
The distance to the library is 540 meters.
Let x represent time in seconds
So, kendal travel = 6x
So, distance between Kendal and the library before she passes it:
=540 − 6x.
Now, Kendal will be 60 meters away from the library.
Kendal will be 60 meters away from the library
540 − 6x= 60
-6x= 60-540
-6x= -480
x= -480/-6
x= 80
Hence, the answer is 80

Answer:
See Below (Isolate the variables)
Step-by-step explanation:
13) d = 4AM solve for M
Divide both sides by 4A
[tex]\frac{d= 4AM}{4A}[/tex]
[tex]\frac{d}{4A} = M[/tex]
14) [tex]\frac{A}{6}[/tex] = f+h solve for A

Step-by-step explanation:
Find the value of x.
(2x + 4)
(3x + 1)
Answer: x= 17°
Step-by-step explanation:
The interior angle of a triangle adds up to 180 degrees. It indicates that it is a right triangle so it already has a 90 degree angle and if you add it to the two other angles they have to equal 180 degrees.
(2x + 4 ) ( 3x + 1) + 90 = 180
5x + 95 = 180
-95 -95
5x = 85
x = 17

The robotics team needs to purchase $350 of new equipment. Each of the students on the team plans to fundraise and contribute equally to the purchase. Which expression represents the amount that each student needs to fundraise? Which expression represents the amount that each student needs to fundraise? Explain your thinking.
Answer:
s = students, m = money they pay
S(M)=350
The expression that represents the amount that each student needs to fundraise is - y = [tex]$\frac{350}{x}[/tex]
We have robotics team who needs to purchase $350 of new equipment.
We have to determine the expression which represents the amount that each student needs to fundraise.
In a class of 50 students, it was asked to collect a total of $3000 for NGO funding. Find the amount contributed by each student assuming they all pay the equal amount.Assume the amount paid by each student be x. Then -
50x = 3000
x = $60
According to the question, we have -
Assume that the number of students in the robotics team are x.
Assume that the money contributed by each member is $y.
Then, the expression represents the amount that each student needs to fundraise is -
xy = 350
y = [tex]$\frac{350}{x}[/tex]

A square patio has an area of 135 square feet.How ling is each side of the patio to the nearest tenth?
Answer:
[tex]\boxed {\tt 11.6 \ feet}[/tex]
Step-by-step explanation:
The area of a square can be found using the following formula.
[tex]A=s^2[/tex]
We know the area of the patio is 135 square feet. Substitute 135 ft² in for A.
[tex]135 \ ft^2=s^2[/tex]
We want to find the side length. We must isolate the variable, [tex]s[/tex]. on one side of the equation.
s is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.
[tex]\sqrt{135 \ ft^2} =\sqrt{s^2}[/tex]
[tex]\sqrt{135 \ ft^2} =s[/tex]
[tex]11.61895 \ ft =s[/tex]
Round to the nearest tenth. The 1 in the hundredth place tells us to leave the 6 in the tenth place.
[tex]11.6 \ ft \approx s[/tex]
Each side of the patio is about 11.6 feet.

Solve -9(t - 2) = 4(1-15).
Answer:
t = 74 / 9
Step-by-step explanation:
-9(t - 2) = 4(1 - 15)
-9t + 18 = 4 - 60
-9t + 18 = -56
-18 -18
-9t = -74
/-9 /-9
t = 74 / 9
t = 8.22
Answer:
t = 74 / 9 ~= 8.222
Step-by-step explanation:
-9 ( t - 2 ) = 4 ( 1 - 15 )
-9 * t + -9 * -2 = 4 * 1 + 4 * -15
-9t + 18 = 4 + -60
-9t + 18 = -56
-9t = -56 + -18
-9t = -74
t = 74 / 9
Alternatively:
-9 ( t - 2 ) = 4 ( 1 - 15 )
-9 * t + -9 * -2 = 4 ( - 14 )
-9t + 18 = -56
-9t = -56 + -18
-9t = -74
t = 74 /9
