Solve the formula a(m+r) -t=s for a.
9514 1404 393
Answer:
a = (s +t)/(m +r)
Step-by-step explanation:
Add t, then divide by the coefficient of 'a'.
[tex]a(m+r)-t=s \qquad\text{given}\\\\a(m+r)=s+t \qquad\text{add $t$}\\\\\boxed{a=\dfrac{s+t}{m+r}} \qquad\text{divide by $m+r$}[/tex]

Marina Polyakova pays a total of $1150 per month for rent and electricity. It costs $650 more for rent per month than for electricity. What are the costs for each?
Answer:
900 and $250
Step-by-step explanation
Given data
Total cost of utilities per month =$1150
Let the cost of rent be x
And the cost of electricity be y
x+y=1150---------1
It costs $650 more for rent per month than for electricity
x=x+650-------2
From equation 1
x+x+650=1150
2x=1150-650
2X=$500
x=500/2
x=$250
Hence the cost of electricity is $250
And the cost of rent is $650+250
=$900
There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099
Can someone write logb(xy) as two logs (49 points)
Answer:
log b (xy) = log b (x) + log b (y)Step-by-step explanation:
Log of the product is equal to the sum of the logs
log b (xy) = log b (x) + log b (y)In which quadrant does 694 lie?
Answer: C. quadrant l
Step-by-step explanation:
Angle 694° lies Quadrant IV which is correct option (D)
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values
What is the quadrant?A quadrant is defined as an area contained by the x and y axes, which there are four quadrants in a graph.
For Quadrant I : the value of x and y both are positive ( +,+ )
For Quadrant II : the value of x is negative and y is positive ( -,+ )
For Quadrant III : the value of x is negative and y is negative ( -, - )
For Quadrant IV : the value of x is positive and y is negative ( +, - )
Locate the quadrant of the angle.
If the angle is greater than 360°,
Subtract 360° until the angle is less than 360°.
⇒ 694 - 360
⇒ 334°
Hence, angle 694° lies Quadrant IV

Mode ??
Median ??
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
Mode: no mode
No mode because there are no repeating numbers.
Median=7
Put in order from least to greatest- 1,6,7,42,81
Find the one in the middle- 7

What number is 56% of 400? Show ALL of your work.
Answer: 224
Step-by-step explanation:
56% is the same as saying (56/100). When finding a percent of a number, you’re really setting up a ratio with the value x:
(56/100)=(x/400)
Then you just cross multiply:
(56 x 400)/100=x
x=224

Answer:
i think (0,2)
Step-by-step explanation:
Write an equation that is perpendicular to the line y = 5x - 1 and passes through the point (10, 8)
Answer:
y = -1/5 x + 10
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given the equation y = 5x -1
Slope m = 5
Slope of the line perpendicular to the line will bw M = -1/5
Substitute into the equation
y - 8 = -1/5(x-10)
5(y-8) = -(x-10)
5y - 40 = -x+10
5y = -x+10+40
5y = -x+50
y = -1/5 x + 10
Hence the required equation is y = -1/5 x + 10

Find the values of x and y.
Answer:
x = 15; y = 21
Step-by-step explanation:
The vertical angles have the same measure.
The sum of the measures of the angles of a triangle is 180 deg.
Left triangle:
4y - 18 + y + 14 + 6x - 11 = 180 Equation 1
Right triangle:
6x - 11 + 81 + x + 5 = 180 Equation 2
Simplify Equation 1.
4y - 18 + y + 14 + 6x - 11 = 180
6x + 5y = 195 Equation 3
Simplify Equation 2.
6x - 11 + 81 + x + 5 = 180
7x = 105
Solve last equation for x.
7x/7 = 105/7
x = 15
Substitute 15 for x in Equation 3 and solve for y.
6x + 5y = 195
6(15) + 5y = 195
90 + 5y = 195
5y = 105
y = 21
Answer: x = 15; y = 21
