The dry cleaning fee for three pairs of pants is $18. How much will it cost to clean 11 pairs of pants?
2m+(m-15)=90 solve for m
Answer:
m = 35
Step-by-step explanation:
2m + m -15 = 90
3m -15 = 90
+15 +15
3m = 105
/3 /3
m = 35
To check the work just insert 35 for m:
2(35) + 35 -15 = 90
70 + 35 -15 = 90
105 - 15 = 90
90 = 90

1 The graph shows the relationship between the weights of 5 packages and the shipping charge for each package. Is the relationship represented by the graph a function? Explain. I
Answer:
Step-by-step explanation:
Yes, each input value is paired with only one output value.
The function represent the given graph is f(x)=0.67x+1.83.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the graph, the coordinate points are (1, 2.5) and (2.5, 3.5)
Here, slope m=(3.5-2.5)/(2.5-1)
= 1/1.5
= 0.67
Substitute m=0.67 and (x, y)=(1, 2.5) in y=mx+c, we get
2.5=0.67+c
c=1.83
Substitute m=0.67 and c=1.83 in y=mx+c, we get
y=0.67x+1.83
Therefore, the function represent the given graph is f(x)=0.67x+1.83.

of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm
Answer:
G. 12 cm
Step-by-step explanation:
Length of one leg of right triangle = a = 9 cm
Length of hypotenuse = c = 15 cm
Length of the other leg = b = ?
Applying pythagorean theorem, c² = a² + b², we have:
15² = 9² + b²
15² - 9² = b²
144 = b²
b = √144
b = 12

After taking a 70 point test, a student guesses that he got 65 points correct. Later he finds out he got 67 points
correct. Calculate the percent error of his guess to 3sf.
Answer:
Percent error = 4.29%
Step-by-step explanation:
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 67
Theoretical value = 70
Substituting into the equation, we have;
[tex] Percent \; error = \frac {67 - 70 }{ 70} *100[/tex]
[tex] Percent \; error = \frac {3}{70} *100[/tex]
[tex] Percent \; error = 0.04286 *100[/tex]
Percent error = 4.29%
Find sin D and sin E. Write each answer as a fraction and as a decimal. Round to four decimals places.
Answer/Step-by-step explanation:
✔️Sin D = opp/hyp
Opp = 12
Hyp = 15
Sin D = 12/15 = 4/5 (as fraction )
Sin D = 0.8 (as decimal)
✔️Sin E = opp/hyp
Opp = 9
Hyp = 15
Sin E = 9/15 = 3/5 (as fraction)
Sin E = 0.6 (as decimal)
One of the legs of a right triangle is 9 cm. If the area of the triangle is 225 cm², then the length of the other leg is
if you tell correctly I will give brainlist
Given:
One of the legs of a right triangle is 9 cm.
The area of the triangle is 225 cm².
To find:
The length of the other leg.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]
The area of a right triangle is
[tex]Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)[/tex]
Let x be the length of other leg.
[tex]225=\dfrac{1}{2}\times (9)\times (x)[/tex]
[tex]2\times 225=9x[/tex]
[tex]\dfrac{450}{9}=x[/tex]
[tex]50=x[/tex]
Therefore, the length of the other leg is 50 cm.

Consider the following equation
3x + 9y = 8y - 2
Step 2 of 2: Find the equation of the line which passes through the point (13,5) and is perpendicular to the given line. Express your answer in
slope-intercept form. Simplify your answer.
Answer:
The perpendicular line is:
y = 1/3 x + 2/3
Step-by-step explanation:
The given equation can be reduced to its slope-intercept form as shown below:
3x + 9y = 8y - 2
subtract 8 y from both sides
3 x + y = -2
subtract 3 x from both sides
y = - 3 x -2
therefore we know that the slope of this line is -3, and then, a perpendicular line to it must have slope given by the "opposite of the reciprocal" of this slope. That is, the slope of any perpendicular line to this one must be: 1/3
We use this slope to find the equation of the line passing through the point (13. 5)
y = 1/3 x + b
passing through (13, 5) means:
5 = 1/3 (13) + b
therefore, we can find b from the above equation
b = 5 - 13/3 = 15/3 - 13/3 = 2/3
Then the equation of this perpendicular line is:
y = 1/3 x + 2/3

[3(x+2)*10*7]÷70 - 2(x+2)
= 3(x+2)*70÷70 - 2(x+2)
