4*10=40
Find the area of the Triangle
11*4=44
44÷2=22
Add
40+22=62
Solve the simultaneous equations
5x + y = 21
3x + y = 13
X =
Y =
Answer:
x=? y=?
5x+y=21 equation 13x+y=13y=13-3x
y=13-3x in equation 15x+(13-3x)=21
5x+13-3x=21
2x+13=21
2x=21-13
2x=8
x=8/2
x=4
x=4 in equation 15(4)+y=2120+y=21
y=21-20
y=1

Step-by-step explanation:
Fred purchased a piece of artwork for 6200, and it is expected to increase in value by 5% per year. Write a function y to represent the value of the piece of artwork after v years.
Answer:
y = a(1 + r) ^v
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v
Step-by-step explanation:
Fred purchased a piece of artwork for 6200, and it is expected to increase in value by 5% per year. Write a function y to represent the value of the piece of artwork after v years.
The function we can used to represent the above question is given as Exponential Growth function.
Where the number of years = v
The value of the artwork = y
y = a(1 + r) ^v
Where
a = Initial value of the artwork = 6200
r = Growth rate = 5% = 0.05
v = number of years
Therefore, the function y to represent the value of the piece of artwork after v years is written as:
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v

Jenny drives from Paris to Rochefort, a distance of 483 km. her average speed on the journey is 84 km/h, she leaves at 9:50. What time does she arrive in Rochefort
The correct answer is 3: 35
Explanation:
To calculate at what time Jenny will arrive in Rochefort, the first step is to calculate the approximate time of the trip. Now, to calculate this consider the time of a movement (t) equals to the distance (d) divided by the speed (s), the process is shown below:
t = 483 km / 84 km/h
t = 5.75 hours
In this number 5 refers to the hours and 0.75 represents 45 minutes considering 0.75 x 60 minutes in one hour = 45 minutes. Therefore, the total time from Paris to Rochefort is 5 hours and 45 minutes. Now, to calculate the time of arrival add this result to the time of departure.
Add the hours: 5 hours + 9 hours: 14 hours
Add the minutes: 50 minutes + 45 minutes =95 minutes
95 minutes are equivalent to 1 hour (60) minutes and 35 minutes
Calculate the total
Hours: 14 hours + 1 hour = 15 hours or 3 in the 12 hour system (15 hours - 12 hours = 3 p.m.)
Minutes: 35 minutes

Step-by-step explanation:
Mathematically;
csc 2 theta = 1 / sin 2 theta
Sin 2 theta = sin (theta + theta)
= 2sin theta cos theta
So therefore;
csc 2 theta = 1/2(sin theta cos theta)
= 1/2 * 1/sin theta * 1/ cos theta
1/sin theta = csc theta
1/cos theta = sec theta
Thus;
csc 2 theta = 1/2 * csc theta * sec theta
csc 2 theta = 1/2 sec theta csc theta
-x/6 + 6 = 32
What is the answer and how do I solve it
Answer:
x= -120
Step-by-step explanation:
-x/6+6+6=32
Use -a/b=a/-b= -a/-b to rewrite the fraction.-x/-6+6+6=32Add the two 6's then you get 12-x/-6+12=32Multiply both sides with the equation by 6 -x+72=192Move the constant to the right-hand side and change its side -x=192+72Subtract the numbers, -x=192-72-x=120Change the signs on both sides of the equationYou have your answer it is x= -120Nikki has $1100 and spends $35 per week. Mich has $520 and saves $55 per week. In about how many weeks, will Nikki and Micah have the
same amount of money?
(round to the nearest whole number)
Answer:
6 weeks
Step-by-step explanation:
Given that :
Nikki :
Initial amount = $1100 ;
Amount spent per week = $35
Mich:
Initial amount = $520
Amount saved per week = $55
Number of weeks they'll both have the same amount :
Let number of weeks = w
For Nikki who is spending :
1100 - 35w - - - (1)
For Mich who is saving :
520 + 55w - - - (2)
Equate (1) and (2)
1100 - 35w = 520 + 55w
1100 - 520 = 55w + 35w
580 = 90w
w = 580 / 90
w = 6.444
About 6 weeks

Equation Editor The coordinates of points A and B are (−7, 5) and (4, −3), respectively. What is the distance, in units, between the points?
Answer:
√185 = 13.6
Step-by-step explanation:
Distance² = (x' - x)² + (y' - y)²
Distance² = (-7 - 4)² + (5 - -3)² = (-11)² + (8)² = 121 + 64 = 185
Distance = √185

ok im not good at math but les see how this goes errr
Step-by-step explanation:welp i think it s35 beAZcausee im smART :))))
your welcome
you can thank me later :))\
=================================================
Explanation:
Let y be the unmarked angle to the right of (x+85). Since angle (x+85) and angle y form a straight angle, we know that (x+85)+y = 180.
We also know that y = 60 since line a is parallel to line b, and corresponding angles are congruent when we have parallel lines.
So (x+85)+y = 180 updates to (x+85)+60 = 180
-------
Let's solve for x
(x+85)+60 = 180
x+85+60 = 180
x+145 = 180
x = 180-145
x = 35
The Baking Club is selling pies during lunch to raise money to go to baking competition. Each pie is cut into 8 slices. The club made a certain amount of pies, and the cafeteria staff donated 2 pies. If there were a total of 80 pie pieces to sell, how many pies did the Baking Club make?
Answer:
the baking club made 8 pies
Step-by-step explanation:
80 (the total amount of peices) devided by 8 (the amount each is sliced into) is equal to 10
10 - 2(the two pies donated) = 8
the baking club baked 8 pies
