Answer:
9/11
Step-by-step explanation:
Let r = number of red gems
Let n = number of green gems
Let p = number of gold gems
n= (1/3)r - - > multiply both sides by 3 - - > r = 3n
r = (1/6)p - - > multiply both sides by 6 - - > p = 6r
So the number of reds (r) is 3x the number of greens (n)
And the number of golds (p) is 6x the number of reds.
So for every 1 green, we have 3 reds and for every red we have 6 golds.
So for every 1 green, we have 3 reds and 18 golds.
So we add 1 + 3 + 18 = 22 gems.
Out of the 22 gems, 18 are gold.
18/22 = 9/11 are gold

Differentiate f() = ( − cos()) sin()
Answer:
1
Step-by-step explanation:
f'(x) = -d(cos(x))/dx*sin(x) + d(sin(x))/dx * cos(x)
f'(x) = sin(x) * sin(x) + cos(x)*cos(x)
f'(x) = 1

CAN SOMEONE TELL ME THE AREA PLEASE
Answer:
1.3 m²
Step-by-step explanation:
The shape is a trapezoid.
Area of a trapezoid = ½(a + b)*h
Where, a = 0.8 m
b = 1.8 m
h = height of the trapezoid which is not given.
Therefore, find h using trigonometric function with 45° as reference angle:
Hypotenuse = 1.4 m
Opposite = h
Apply SOH, which is:
Sin 45 = Opp/Hyp
Sin 45 = h/1.4
1.4*Sin 45 = h
0.989949493 = h
h ≈ 1.0 m
✔️Area of Trapezoid = ½(0.8 + 1.8)*1 = 1.3 m²

Answer:
x=10, y=-1
Step-by-step explanation:
Multiply both sides of the top equation by 2 to get 2x-2y=22
subtract the two equations
2x-2y=22
2x+y=19
-3y=3
y=-1
plug the -1 in any of the two equations (I'll do the second one)
2x-1=19
2x=20
x=10
x=10, y=-1

Find the values of m and n.
A. m = 60, n = 12
B. m = 50, n = 20
C. m = 50, n = 16
D. m = 60, n = 24
Answer:
D. m= 60, n= 24
Step-by-step explanation:
The angle marked with blue, will also be 2m° (Vertically opposite angles)
So, 2m = (4m- 120)°
2m = 120°
m = 60°
Now, (4m-120)° = 5n° (Vertically opposite angles)
[4(60)- 120]° = 5n°
240- 120 = 5n°
120/5° = n
n= 24°

Use the estimates from (c) and (d) to calculate the relative change in the average household
income from 2002 to 2012. Round to the nearest one percent. Indicate if the change is an
increase or decrease.
Answer:
it decreased by 5.55% change of 6%
The relative change is -6% Rounding to the nearest percent.
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
The relative change can be calculated by dividing the absolute change (the subtraction of the values) by the initial value.
The absolute change is the final value minus the initial value;
Absolute change = 51000 - 54000 = -3000
Now, calculating the relative change;
Relative = -3000/54000
Relative = - 0.0555
Since the relative change is negative, this change indicates a decrease.
Therefore, the relative change is -6% Rounding to the nearest percent.

Multiply the first equation by 3/2:
3/2×8x + 3/2×2y = 3/2×46 12x + 3y = 69Subtract the second equation:
12x - 7x = 69 - 475x = 22x = 4.4Find y:
4*4.4 + y = 23y = 23 - 17.6y = 5.42.
Double the second equation and subtract the first one:
14x - 4x = 94 - 6210x = 32x = 3.2Find y:
4*3.2 + 6y = 626y = 62 - 12.86y = 49.8y = 8.33.
Subtract the second equation from the first one:
4x - 2x = 62 - 762x = -14x = -7Find y:
4(-7) + 6y = 626y = 62 + 286y = 90y = 154.
Multiply the second equation by 4 and subtract the first one:
16y - y = 4(98) - 4315y = 349y = 349/15y = 23 4/15Find x:

The parent exponential function of f(x)=2x has been transformed in the following ways:
-a vertical compression by a scale factor of 13
-a vertical translation of 3 units up
-and a horizontal translation of 3 units to the left
Answer:
The resulting expression is [tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]. We include the graph of both functions, the red line represents the parent exponential function, whereas the blue line is for the resulting function.
Step-by-step explanation:
Statement is incomplete. The question is missing. We infer that question is: What is the resulting expression? Let [tex]f(x) = 2^{x}[/tex], each operation is defined below:
Vertical compression
[tex]g(x) = k\cdot f(x)[/tex], where [tex]0 < k < 1[/tex]. (1)
Vertical translation upwards
[tex]g(x) = f(x) + c[/tex], where [tex]c > 0[/tex]. (2)
Horizontal translation leftwards
[tex]g(x) = f(x+b)[/tex], [tex]b > 0[/tex]. (3)
Now, we proceed to transform the parent exponential function:
(i) A vertical compression by a scale factor of 13 ([tex]k = \frac{1}{13}[/tex])
[tex]f'(x) = \frac{1}{13}\cdot 2^{x}[/tex]
(ii) Vertical translation of 3 units up
[tex]f'' (x) = \frac{1}{13}\cdot 2^{x} + 3[/tex]
(iii) Horizontal translation of 3 units to the left
[tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]
The resulting expression is [tex]g(x) = \frac{1}{13}\cdot 2^{x+3}+3[/tex]. We include the graph of both functions, the red line represents the parent exponential function, whereas the blue line is for the resulting function.

Answer: Melanie has the most money at the end of the week.
Step-by-step explanation:
Melanie gets the 1 weekly allowance. But it could also depend on how much her weekly allowance is. Your bus rides aren't a lot, so riding the bus 7 times doesn't take much money. She also gets paid for 2 hours, so she could be working somewhere with more money being paid by the hour. While on the other hand, Dana could be working a minimum wage job and wasting more money, because she also pays for food. She could be on her own and have to spend more money for her needs and the things she would need. (And because it says Melanie gets 1 weekly allowance that means she still lives with her parents so they pay for her benefits and things she needs.)

Calculate the amount of money you'll have at the end of the indicated time period, assuming that you earn simple interest. You deposit $3400 in an account with an annual interest of 4.5 % for 20years. The amount of money you'll have at the end of the years is
Answer:
The amount of money you'll have at the end of the years is 6460 dollars
Step-by-step explanation:
The total principal sum of money deposited = [tex]3400[/tex] dollars
The annual rate of interest is [tex]4.5[/tex] %
The time period for which the amount is invested [tex]= 20[/tex] years
As we know
[tex]A = P (1 + rt)[/tex]
where A is the amount after 20 years
P is the principal sum of money
r is the rate of interest and
t is time period in years
Substituting the given values in above equation, we get -
[tex]A = 3400 (1 + \frac{4.5}{100} * 20)\\A = 6460[/tex]dollars

What is the measure of angle 6, to the nearest degree?
9514 1404 393
Answer:
99°
Step-by-step explanation:
If we assume that angles 5 and 7 are vertical angles, they are congruent:
10x -9 = 9x
x = 9 . . . . . . . add 9-9x
Then angles 5 and 7 are ...
(10·9 -9)° = 9·9° = 81°
Angle 6 will be the supplement to this.
angle 6 = 180° -81°
angle 6 = 99°

the answer is not 99

Determine the multiplier in each situation below.
a. A 44% increase
b. A 93% decrease
Answer:
Step-by-step explanation:
%s can drive a person crazy.
44% increase
Cost = 100% * x + 44%x
Cost = x ( 100 / 100 + 44/100)
Cost = x (1 + 0.44)
Cost = 1.44 x
93% decrease
Cost = 100%x - 93%x
Cost = x * (100/100 - 93/100)
Cost = x * (1 - 0.93
Cost = 0.07 x
Answer:
1.44 and 0.07
Step-by-step explanation:
(a)
A 44% increase of the original amount (100%) is
100 + 44 = 144% = [tex]\frac{144}{100}[/tex] = 1.44 ← multiplier
(b)
A 93% decrease of the original amount (100%) is
100 - 93 = 7% = [tex]\frac{7}{100}[/tex] = 0.07 ← multiplier
