Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?


(Also if u can pls type out ur answer like "10 weeks and $100" hehe)

Answer: b = 9

Step-by-step explanation:

Given

12 + 5/3b + 11 - 18 = 20

Combine like terms

(12 + 11 - 18) + 5/3b = 20

5 + 5/3b = 20

Subtract 5 on both sides

5 + 5/3b - 5 = 20 - 5

5/3b = 15

Divide 5/3 on both sides

5/3b / (5/3) = 15 / (5/3)

b = 9

Answer:

x = 23

Step-by-step explanation:

7 + 2x = 53

7 + 2x - 7 = 53 - 7

2x = 46

2x / 2 = 46 / 2

x = 23

Answer:

x = √3

Step-by-step explanation:

Looking at the given triangle,

x is the adjacent side while 2 represents the hypotenuse side.

Now, from trigonometric ratios, we know that;

Adjacent/hypotenuse = cos θ

The angle here will be 30°

Thus;

x/2 = cos 30°

We are told to find x in simplest radical form with a rational denominator.

Thus means we will use the surf value of the angle.

cos 30° in surd form = (√3)/2

Thus;

x/2 = (√3)/2

x = 2 × (√3)/2

x = (√3)/1

x = √3

Answer:

the inequality will be X > 73

Step-by-step explanation:

when you move COUNTERclockwise, you go in the opposite direction that a clock goes, so you would go to the left instead of the right

Answer:

[tex]G' = (3,1)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I' = (-2,-3)[/tex]

Step-by-step explanation:

Given

See attachment for points G, H and E

Rotation: 90 degrees clock-wise

Required

Determine the coordinates after rotation

From the attachment:

[tex]G = (-1,3)[/tex]

[tex]H = (0,-4)[/tex]

[tex]I = (3,-2)[/tex]

When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)

So, we have:

[tex]G = (-1,3)[/tex]

[tex]G' = (3,1)[/tex]

[tex]H = (0,-4)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I = (3,-2)[/tex]

[tex]I' = (-2,-3)[/tex]

Answer:

James = £60, Ryan = £40 and Jill = £20

Step-by-step explanation:

James - 3, Ryan - 2 and Jill - 1

3 + 2 + 1 = 6

£120 / 6 = 20

Times 20 by each of the three numbers (3, 2 and 1)

3 x 20 = £60 (James)

2 x 20 = £40 (Ryan)

1 x 20 = £20 (Jill)

Answer:

James gets £60

Ryan gets £40

Jill gets £20

Step-by-step explanation:

Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20

All these should add up to your original sum and if they do you know you've done it right!

Answer:

[tex]v = 400000(2^\wedge d)[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Value = \$400000[/tex]

[tex]Rate = doubles[/tex] per decade

Required

Determine the equation of the function

The information given shows that the function is exponential and will be calculated using:

[tex]v = ab^d[/tex]

Where:

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So, we have:

[tex]v = 400000* 2^\wedge d[/tex]

[tex]v = 400000(2^\wedge d)[/tex]

The equation that represents the value of the home is v = $400,00(2^d).

The home is appreciating in value. This means that the price of the house is increasing with the passage of time.

The formula that can be used to represent the appreciation is:

FV = P (1 + r)^n

v = $400,000(2^d)

Vertices:[tex](0,\pm 1)[/tex]

Eccentricity, e=[tex]\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

We are given that

[tex]y^2-16x^2=1[/tex]

[tex]y^2-\frac{x^2}{(\frac{1}{4})^2}=1[/tex]

The equation of hyperbola is along y-axis because y is positive

Compare the equation with

[tex]y^2/a^2-x^2/b^2=1[/tex] (Along y-axis)

We get

a=1, b=1/4

[tex]a^2+b^2=c^2[/tex]

[tex]1+\frac{1}{16}=c^2[/tex]

[tex]\frac{16+1}{16}=c^2[/tex]

[tex]c^2=\frac{17}{16}[/tex]

[tex]c=\pm \frac{\sqrt{17}}{4}[/tex]

Therefore,

The coordinates of foci=[tex](0,\pm c)=(0,\pm\frac{\sqrt{17}}{4})[/tex]

The coordinated of vertices=[tex](0,\pm a)=(0,\pm 1)[/tex]

Eccentricity, e=c/a

[tex]e=\frac{\frac{\sqrt{17}}{4}}{1}=\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{2b^2}{a}[/tex]

Length of latus rectum=[tex]2\times \frac{1}{16}=\frac{1}{8}[/tex]
