Answer:

a) the ratio is 9:4

b) Hilda did save $16.

Step-by-step explanation:

Let's define the variables:

C = Cheryl's savings.

H = Hilda's savings.

We know that:

(1/3)*C = (3/4)*H

We also know that Cheryl saved $36, then we have:

C = $36

Now we can replace that in the above equation to get:

(1/3)*$36 = (3/4)*H

$12 = (3/4)*H

$12*(4/3) = H = $16

Then Hilda did save $16.

And the ratio between of Cheryl's savings to Hilda's savings is:

36 : 16

We can simplify this if we divide both by 2.

(36/2) : 16/2

18 : 8

Again, we can divide both by 2:

(18/2) : (8/2)

9 : 4

Then the ratio is 9 : 4

Answer:

P = A / (1 + r/100)ᵗ

Step-by-step explanation:

A = P(1 + r/100)ᵗ

We can make P the subject of the above expression as follow:

A = P(1 + r/100)ᵗ

Divide both side by (1 + r/100)ᵗ

P = A / (1 + r/100)ᵗ

Therefore, making P the subject of

A = P(1 + r/100)ᵗ, we have

P = A / (1 + r/100)ᵗ

Answer:

option a 21 is the right answer

Step-by-step explanation:

7/12.36

12 into 3 is 36

so 12 1's are and 12 3's are

now it'll become 7 into 3

which is 21

therefore 21 is the answer

Step-by-step explanation:

Step 1: Define

Center (2, -3) → x₁ = 2, y₁ = -3

Circumference point (-1, -2) → x₂ = -1, y₂ = -2

In this case, the distance d from the center to the circumference point would be the radius r of the circle.

Step 2: Find Radius r

Answer:

  (d)  x = 3

Step-by-step explanation:

The "vertex form" of the equation of a parabola is ...

  y = a(x -h)² +k

In this form, the vertex has coordinates (h, k).

Comparing the form to your equation, you see that h=3, k=4, so the vertex is (h, k) = (3, 4).

The line of symmetry is a vertical line through the vertex. It will have the same x-value as the x-coordinate of the vertex:

  x = 3

_____

In short, the equation of the line of symmetry has its constant equal to the opposite of the value added to x. Here, the added constant is -3, so the line of symmetry is x=3.

The values h and k in the vertex-form equation represent the amount of translation right and up from the parent function graph. When the graph is translated 3 units to the right, the line of symmetry moves from x=0 to x=3.

Answer:

48.14= $58.25

$97.92= 81.27 euro

Step-by-step explanation:

Giving the following information:

1 Euro is currently valued at 1.21 U.S. Dollars.

First, we need to calculate the dollar value of 48.14 euros.

Proportion equation used for answer below: 1e= 1.21d

48.14*1.21= $58.25

Now, the euro value of 97.72 dollars.

Proportion equation used for answer below: (1:1.21) 0.83

1 dollar equals 0.83 euro.

97.92*0.83= 81.27 euro

Answer:

Area = 1808.64 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference = 150.72

π = 3.14

r = radius

150.72 = 2 x 3.14 x r

150.72 = 6.28 r

r = 150.72/6.28

r = 24cm

Radius = 24

Area of a circle = πr²

Area = 3.14 x 24²

Area = 3.14 x 576

Area =1808.64 cm

Answer:

1808.64 cm

Answer:

C. 21π cm³

Step-by-step explanation:

Use volume formula for cone

[tex]V = \pi r^{2} \frac{h}{3}[/tex]

r = 3cm

h = 7cm

[tex]V = \pi (3)^{2} * \frac{7}{3}[/tex]

[tex]V = \pi 9 * \frac{7}{3}[/tex]

[tex]V = \pi \frac{63}{3}[/tex]

[tex]V = 21 \pi[/tex]

Answer:

[tex]t = \frac{1}{4}\sqrt d[/tex]

Time to reach 100ft is 2.5 seconds

Step-by-step explanation:

Given

[tex]d = 16t^2[/tex]

Solving (a): Determine the inverse function

[tex]d = 16t^2[/tex]

Swap the positions of d and t

[tex]t = 16d^2[/tex]

Make d the subject

[tex]\frac{t}{16} = d^2[/tex]

Take positive square root of both sides

[tex]\sqrt{\frac{t}{16}} = d[/tex]

[tex]d = \sqrt{\frac{t}{16}}[/tex]

[tex]d = \frac{1}{4}\sqrt t[/tex]

Swap the positions of d and t

[tex]t = \frac{1}{4}\sqrt d[/tex] --- The inverse function

Solving (b): Find t when d =100

Substitute 100 for d in [tex]t = \frac{1}{4}\sqrt d[/tex]

[tex]t = \frac{1}{4}\sqrt {100[/tex]

[tex]t = \frac{1}{4}* 10[/tex]

[tex]t = \frac{1* 10}{4}[/tex]

[tex]t = \frac{10}{4}[/tex]

[tex]t = 2.5[/tex]
