Answer:
Step-by-step explanation:
think of this as a system of equations where the colors just represent a variable like x or y
I'll just arbitrarily set colors to some variable letter so we have
purple = x
green =y
blue =z
red = a
yellow = b
so we can now rewrite the 4 known equations of the system :)
Eq. 1) x+y = 13
Eq. 2) 2y+2z=18
Eq. 3) 2x+3y=31
Eq. 4) z + 4a = 12
Eq. 5) a * y = b
so solve the 1st eq for y => y =13-x then plug that into the 3rd eq and slove for x => 2x + 3(13-x) =31
2x + 39 -3x = 31
2x-3x = 31 - 39
-x = -8
x=8
plug 8 into Eq. 1 for x and solve for y
8+y = 13
y=5
plug y into Eq 1 and solve for z
2(5) +2z = 18
10 +2z = 18
2z = 8
z = 4
plug z into E1 4 and solve for a
4 + 4a = 12
4a = 8
a = 2
plug a and y into Eq 5 and solve b
2 * 5 = b
10=b
go to the drawing and plug in each of the color values that we put as variable letters above and get an A+ on your homework.. :)
7.74% of 789.13
Give your answer rounded to 2 DP.
Given :
A number 789.13 .
To Find :
7.74% of 789.13 .
Solution :
Let, 7.74% of 789.13 is x.
So,
[tex]x = \dfrac{789.13\times 7.74}{100}\\\\x = \dfrac{6107.8662}{100}\\\\x = 61.08[/tex]
Therefore, 7.74% of 789.13 upto 2 decimal place 61.08 .

10 builders can build a house in 20 days. How many builders
will you need build the house in 10 days?
Answer:
20 builders
Step-by-step explanation:
Answer: 20 builders.
Step-by-step explanation: For 10 builders to build a house in 20 days, the ratio is 1:2. For builders to build a house in 10 days, the ratio is x:10. You then cross multiply 1:2 and x:10. Then x=20 so 20 builders.

Bens living room is a rectangle measuring 9 yards by 150 inches. By how many feet does the length of the room exceed the width?
Answer:
14.5 ft or 14 1/2 ft
Step-by-step explanation:
36in= 1 yard
9x36= 324in (I'm guessing this is the length)
324in (length) -150in (width)= 174in
12 in= 1 ft
174/12= 14 ft 6 in
6 inches is half a foot
14.5 ft or 14 1/2 ft
answers for the 2 boxes please
Answer:
(4, 22)
Step-by-step explanation:
y = 5x + 2
y = 3x + 10
Since both equations are equal to y, we can have both equations equal to each other).
5x + 2 = 3x + 10
5x + 2 - 3x - 2 = 3x + 10 - 3x - 2
5x - 3x = 10 - 2
2x = 8
2x/2 = 8/2
x = 4
(Substitute the x value to any equation to solve for y).
y = 5x + 2
y = 5(4) + 2
y = 20 + 2
y = 22
So, the answer is (4, 22).

Step-by-step explanation:
-3t + 6 = 0
1. Subtract 6 from each side
-3t + 6 - 6 = 0 - 6
-3t = -6
2. Divide each side by -3 to isolate t and get the answer to the equation
-3t/-3 = -6/-3
t = 2
You can check your answer by plugging your calculated value back into the equation and evaluating to find that 0 = 0.

Answer: ↓↓↓
Step-by-step explanation:
Part A
131.5 or $131,500 is the starting value of the plane X before it started to depreciate.
Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)
b (m) = 177,233 (0.024)^m
$177,233 is the starting value of plane Y.
The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.
Part C
b (t) = 177,233 (0.024 x 12)^t
b (t) = 177,233 (0.288)^t
I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.
That's it! I hope I'm right because this took a lot of thinking lol

Rabbit populations can double every 30 days. If there are 26 rabbits on a farm, how many rabbits will be on the farm after 240 days? Use the Formula: Future Amount = { ](1+__)^{ }
Answer: 6,656 rabbits.
Step-by-step explanation:
The initial number of rabbits is 26.
We know that every 30 days, this number is doubled.
Then after 30 days, the population of rabbits is: 2*26
After other 30 days, the population will be: 2*(2*26) = 26*(2)^2
After another 30 days, the population will be: 2*26*(2)^2 = 26*(26)^3
The equation for this population can be written as:
P = A*(1 + 1)^(d/30)
where:
A is the initial population, in this case, 26
d is the number of days that have ben passed.
the denominator of 30 is because the population doubles every 3 days, so when d = 30, we will have that d/30 = 1, this is the first time that the population is doubled. When d = 60, d/30 = 2, this is the second time that the population is doubled, and so on.
Then our equation is:
P(d) = 26*(2)^(d/30)
The population after 240 days will be:
P(240) = 26*(2)^(240/30) = 6,656
So after 240 days, there will be 6,656 rabbits.

Answer:
Even if a right solid became oblique, the volume would not change, because the cross sectional area and height would remain the same. Therefore, by Cavalieri's principle, the volume is the same as the original solid.

A circle has equation x2 + y2 = 25
The circle passes through the points A, B, C and D.
Complete the coordinates for A, B, C and D.
A. (5,_)
B.(_,-5).
C. (_,0)
D(0,_)
Answer: A. (5; 0), B. (0; - 5), C. (-5; 0), D. (0; 5).
Step-by-step explanation:
A. (5; _) [x = 5; y - ?]
x² + y² = 25
5² + y² = 25
25 + y² = 25
25 + y² - 25 = 25 - 25
y² = 0
y = 0
A. (5; 0)
B. (_; -5) [x - ?; y = -5]
x² + y² = 25
x² + (- 5)² = 25
x² + 25 = 25
x² + 25 = 25
x² + 25 - 25 = 25 - 25
x² = 0
x = 0
B. (0; - 5)
C. (_; 0) [x - ?; y = 0]
x² + y² = 25
x² + 0² = 25
x² + 0 = 25
x² = 25
x = ± √25 = ± 5
C. (-5; 0) or (5; 0)
Point A has coordinates (5; 0), which means that
point C has coordinates (-5; 0).
D. (0; _) [x = 0; y - ?]
x² + y² = 25
0² + y² = 25
0 + y² = 25
y² = 25
y = ± √25 = ± 5
D. (0; - 5) or (0; 5)
Point B has coordinates (0; -5), which means that
point D has coordinates (0; 5).

Step-by-step explanation:
Find ghe solution to the system. Write your solution as an ordered pair (x,y) with no spaces,no solution,or infinitely many.y=4x and 3x+2y=55
Answer:
The solution of the system is (5, 20).
Step-by-step explanation:
y = 4x and 3x + 2y = 55 are simultaneous equations. To find the unknowns, we have to solve these equations simultaneously.
The first can be rewritten as
4x – y = 0.
Therefore, we have:
4x – y = 0
3x + 2y = 55
Multiplying the first equation by 2 all through, we have
8x – 2y = 0.
So we can now combine the second equation with the first multiplied by 2.
8x – 2y = 0
3x + 2y = 55
Adding these equations we have:
11x = 55
Divide both sides by 11 and we have
x = 5
Substitute x = 5 in equation 1, we have
4(5) – y = 0
y = 20.
Therefore, x = 5 and y = 20.
The solution of the system is (5, 20).
start with x, subtract y, multiply by a, then add z
Robin saves $500 at a yearly simple interest rate of 4%. What is the total amount of money she has after 20 years?
Answer:
Use the equation 500x0.04x20 and then 500x20 and add the sums up and get 10,400 i believe is im wrong sorry :/
$900 is the total amount of money she has after 20 years.
What is simple interest?Simple interest is, by definition, the amount of interest paid on a specific principal sum of money when an interest rate is applied. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
From the formula of simple interest A = P(1 + rt)
Where A = amount earned
P = principal amount
r = rate of interest
t = time
In our case
P = 500
r = 4%
t = 20
Thus,
Amount earned after 20 years = 500(1 + 4*20/100)
Amount earned after 20 years = 500(1 + 4/5)
Amount earned after 20 years = 900
therefore, the total amount of money she has after 20 years is $900.
