Answer:
15:75
Step-by-step explanation:
120 = 3x plus 5x
120 = 8x
120/8 = x
x = 15
3*15 = 45 and 5*15 = 75

Answer:
A = 2x² + x - 45
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × breadth , thus
A = (2x - 9)(x + 5) ← expand using FOIL
= 2x² + 10x - 9x - 45 ← collect like terms
= 2x² + x - 45

the same amount of wages, y, by working the same number of hours, x, in one week?
O Yes, because the slopes of the equations are different so the system of equations will have one solution.
No, because the slopes of the equations are different so the system of equations will have no solutions.
O Yes, because the slopes of the equations are the same so the system of equations will have infinitely many solutions.
No, because the slopes of the equations are the same so the system of equations will have no solutions.
Answer:
first option
They will make the same amount in week 25

The value of the trigonometric equation after transformation is given by the value y = 3 [ sin ( x + 3 ) ] - 2
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be represented as f ( x )
Now , the value of the trigonometric function f ( x ) is
f ( x ) = 3sin ( x )
when the function is translated 3 units to the left and 2 units down , we get
y = 3 [ sin ( x + 3 ) ] - 2
Therefore , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2 and the graph is plotted
Hence , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2

The area of a rectangle is 20 mm2. If the width is 4 mm, find the length?
Answer:
length = 5 mm
Step-by-step explanation:
area = width x length
20 mm² = 4 mm x length
divide both sides of the equation by 4 mm:
length = 5 mm
Answer:
lenght 5

Choose the correct simplification of the expression a^9 multiplied by b^10/a^2 multiplied by b^7
A^11b^17
1/a^11b^17
1/a^7b^3
A^7b^3
Answer:
a^7 b^3
Step-by-step explanation:
The question can be interpreted as
[(a^9)( b ^10)] / [(a^2 )×( b ^7)]
Then we can bring the denominator up, which means the power on the denominator will become (-ve) once it comes to the numerator side. Then we have
a^(9-2) × b^(10-7)
We can simplify by performing substraction on the power
= a^7 b^3

f(x)= - x^2 - 10x
find f(-5)
Answer:
f(- 5) = 25
Step-by-step explanation:
To evaluate f(- 5) , substitute x = - 5 into f(x) , that is
f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

Answer/Step-by-step explanation:
1. B = 180 - (90 + 58) (sum of triangles)
B = 32°
Let's find a and b using trigonometric ratios:
Reference angle = 58°
Opposite = a = ?
Hypotenuse = c = 27
Adjacent = b = ?
✔️To find a, apply SOH:
Sin 58 = Opp/Hyp
Sin 58 = a/27
a = 27*Sin 58
a = 22.8972986 ≈ 22.9 (nearest tenth)
✔️To find b, apply CAH:
Cos 58 = Adj/Hyp
Cos 58 = b/27
b = 27*Cos58
b = 14.3 (nearest tenth)
2. B = 180 - (90 + 63) (sum of triangles)
B = 27°
Let's find a and b using trigonometric ratios:
Reference angle = 63°
Opposite = a = 11
Hypotenuse = c = ?
Adjacent = b = ?
✔️To find b, apply TOA:
Tan 63 = Opp/Adj
Tan 63 = 11/b
b = 11/Tan 63
b = 5.6 (nearest tenth)
✔️To find c, apply SOH:
Sin 63 = Opp/Hyp
Sin 63 = 11/c
c = 11/Sin 63
c = 12.3 (nearest tenth)

im not really sure how to explain it to you but the first one that were positive numbers you can just subtract them and get the answer which i gave the forst five to you and when you are this is just an example of the adding the negative numbers 4. -15 + n = -9 you can subtract it and you'll get -15 - (-9) = -6
but if you put negative six it's gonna be the wrong answer sooo you just switch it to a positive number 6 because if you put -15 + (-6) = -21 and when its like this -15 + n = -9 the answer is smaller that the bigger number sooo the only right thing to do it put the positive 6
i hope i got you understanding it a little more if i didnt im soory i tried but the 5 answers i gave you correct
Suppose you invest money in two accounts. One of the accounts pays 4% interest annually, and
the other account pays 5% interest annually. You have $ 2000 more invested in the account paying
4% than in the account paying 5%. How much do you have invested in the account paying 4% if
you earn $ 670 interest in a year?

It took a lot of plugging in and guessing
The formula used was 16750(1+.04)^1
That equaled 17420

The exact circumference of a circle is 34π meters. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
A = 907.46 [tex]m^{2}[/tex]
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A = [tex]\pi r^{2}[/tex] = 3.14([tex]17^{2}[/tex]) = 3.14(289) = 907.46 [tex]m^{2}[/tex]
One number is 60 more than another. If the larger number is divided by the smaller number, the quotient is 4.
What are the numbers?
Answer:
80 and 20
Step-by-step explanation:
Let the 1st no. be 'x'.
2nd no. should be 'x + 60'.
If the larger no.(x + 60) is divided by the smaller number(x), the quotient is 4.
=> (x + 60)/x = 4
=> x + 60 = 4x
=> 60=4x-x
=> 60=3x
=> 60/3 = x
=> 20 = x
No. are x = 20 and x+60 = 20+60= 80
