Answer:

Daughter is 12 and mother is 48.

Step-by-step explanation:

Let the daughters age be x years now then the mothers age is 4x.

6 years ago the daughter was x-6 years  and the mother was 4x - 6.

So we have the equation:

x - 6 + 4x - 6 = 48

5x - 12 = 48

5x = 60

x = 12

So the daughter is 12 and the mother is 4*12 = 48.

Answer:

Monomial, Binomial, and Trinomial.

Answer:

d ≈ 9.5

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (8, 2) and (x₂, y₂ ) = (- 1, 5)

d = [tex]\sqrt{(-1-8)^2+(5-2)^2}[/tex]

   = [tex]\sqrt{(-9)^2+3^2}[/tex]

   = [tex]\sqrt{81+9}[/tex]

    = [tex]\sqrt{90}[/tex]

    ≈ 9.5 ( to the nearest tenth )

Answer:

x = 0, 2π/3, 4π/3, 2π.

Step-by-step explanation:

cos 2x = 2cos^2x - 1 so

2cos^2x - 1 = cos x

2cos^2x - cos x - 1 = 0

(2cosx + 1)(cos x - 1) =0

cos x = -1/2, 1.

When cos x = 1, x = 0, 2π

when cos x = -1/2, x = 2π/3, 4π/3.

Answer:

70 pi cm

219.80 cm

219.9114858 cm

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

C = pi * 70cm

Using 3.14 for pi

C = 219.80cm

Using the pi button

219.9114858cm

Circumference of circle = 2πr

Hence , r is 35 cm

⇛Circumference of circle = 2πr

⇛Circumference of circle = 2*3.14*35

⇛Circumference of circle = 6.28*35

⇛Circumference of circle = 219.8 cm

Hence , Circumference of circle is 219.8 cm

Answer:

Step-by-step explanation:

The child graph is shifted 9 units to the right. That's what the nine does. The graph also shifts 3 units down when compared to g(x).

I have put a graph in so that you can see the shifts for yourself.

The red line is g(x) = x^4

The blue line is f(x) = (x - 9)^4 - 3

Answer:

20 seconds

Step-by-step explanation:

h(t) = -16t2 + 640t

to find the maximum value =>

h'(t) = 0

-32t + 640 = 0

-32(t -20)= 0

t-20 = 0

t = 20 seconds

Find derivative of h(t)

[tex]\\ \rm\longmapsto \dfrac{d}{dx}(-16t^2+640t)[/tex]

[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]

[tex]\\ \rm\longmapsto -32t+640[/tex]

[tex]\\ \rm\longmapsto -32t+640=0[/tex]

[tex]\\ \rm\longmapsto -32t=-640[/tex]

[tex]\\ \rm\longmapsto t=\dfrac{-640}{-32}[/tex]

[tex]\\ \rm\longmapsto t=20s[/tex]

Answer:

[tex]herre \: total \: angle \: in \: circle = 360 \\ then \\ \: 6x + 1 + x - 19 + 35 = 360 \\ 7x - 18 + 35 = 360 \\ 7x + 17 = 360 \\ 7x = 343 \\ x = \frac{343}{7} = 49 \\ x = 49degree \\ thank \: you[/tex]

6x + 1° + x - 19° + 35° = 360°

6x + x + 1° - 19° + 35° = 360°

7x + 1° - 19° + 35° = 360°

7x + (-18)° + 35° = 360°

7x + 17° = 360°

7x = 360° - 17°

7x = 343°

x = 343° : 7

x = 49°

Answer:

First take 0.23 as 0.23/1

Then Multiply the numerator and denominator by any number, Let us say 100

So it becomes,

0.23 x 100/100

=> 23/100

Part A : D.)

Part B : Length of the sandbox is 10 feet.

Step-by-step explanation:

Given,

Perimeter = 29 ft

We need to find the equation for the perimeter and also the length of the sandbox.

Solution,

Let the width of the sandbox be 'w'.

Now as per question said;

The length of the sandbox is 1 foot longer than twice the width of the sandbox.

So we can say that;

Length =

Now we know that the perimeter is equal to the sum of twice of length and width.

framing in equation form, we get;

Perimeter =

we have given the perimeter, so on substituting the value, we get;

Hence The equation used to find the width is  .

Now we solve for 'w'.

Applying distributive property, we get;

Subtracting both side by '2' we get

Dividing both side by 6 we get;

Width of the sandbox = 4.5 ft

Length of the sandbox =

Hence Length of the sandbox is 10 feet.

Answer:

x = 7

Step-by-step explanation:

Because the points are collinear:

AB + BC = AC

We'll plug in the expressions in terms of x.

(-1 + 2x) + (11) = (3x + 3)

And solve for x. Combine like terms on the left

2x + 10 = 3x + 3

Subtract 3 on both sides

2x + 7 = 3x

Subtract 2x on both sides

7 = x

Hi,

Answer is $0.19

Step-by-step explanation:-

We know that:-

15 dimes = $1.50

20 nickels = $1.00

8 quarters = $2.00

half dollar = $0.50

19 pennies = $0.19

Total = $5.19

Since Billy spended $5, so,

$5.19 - $5 = $0.19
