what is one way to find the number of minutes in 7 hours?

Answer: Choice C

y = 4x

Direct variation

=====================================================

Explanation:

We add 4x to both sides to isolate y. That leads to y = 4x

This is a direct variation equation because it's in the form y = kx, for some constant k.

Answer:

Four possible numbers

-4

-32

-2

-10

Four numbers that are not possible

100

120

20

10

Step-by-step explanation:

I choose the 4 possible numbers because if you add a negative to a negative, the answer will always be a negative. However if you added a positive like 100 to -3, the answer wouldn't be negative so that's why I chose those numbers.

Answer:

Isabella

Step-by-step explanation:

4:2, is Isabella's ratio of honey:lime.

5:4, is Santiagio's ratio of honey:lime.

Therefore, Isabella has 6 equal parts over all and 4/6 of those parts are honey.

Santiago, has 9 equal parts, so he has 5/9 parts of honey.

Next is to make the denominators the same:

That would make the denominators 54 and then you just multiply the opposite denominator to the numerator:

5/9=36/54

4/6=30/54.

This means that Isabella's dressing is sweeter.

I think, I am no t sure

Rates of change are the change of a quantity over another.

The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

The given parameters are:

[tex]\mathbf{A = |5|}[/tex] -- the amplitude

[tex]\mathbf{T = \frac 13}[/tex] --- the period

The position of the mass is modeled by:

[tex]\mathbf{y= Acos(wt)}[/tex]

Where:

[tex]\mathbf{w = \frac{2\pi }{T}}[/tex]

So, we have:

[tex]\mathbf{w = \frac{2\pi}{1/3}}[/tex]

[tex]\mathbf{w = 6\pi }[/tex]

[tex]\mathbf{y= Acos(wt)}[/tex] becomes

[tex]\mathbf{y = |5|cos(6\pi t)}[/tex]

[tex]\mathbf{y = 5cos(6\pi t)}[/tex]

Differentiate

[tex]\mathbf{y' = 5 \times -sin(6\pi t) \times (6\pi)}[/tex]

[tex]\mathbf{y' = -30\pi sin(6\pi t) }[/tex]

When t = 2.1, we have:

[tex]\mathbf{y' = -30\pi sin(6\pi \times 2.1) }[/tex]

[tex]\mathbf{y' = -30\pi sin(12.6\pi) }[/tex]

[tex]\mathbf{y' = -30\pi \times 0.9510}[/tex]

[tex]\mathbf{y' = -89.6296}[/tex]

Approximate

[tex]\mathbf{y' = -89.6}[/tex]

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

Let's find the slope of the line using the points (0 , 4) and (-8 , 0) from the given graph :

Slope (m) :

hence, the correct choice is C

Answer:

To find the area of the shaded region

A = Area of circle - Area of square

12cm is the diagonal of the square and diameter of the circle.

To find the side of the square,

d = √2 * s

12cm = √2 * s

s = 8.49cm

Area of square = L²

As = (8.49)²

As = 72.1cm²

Area of circle = πr²

r = 6cm

Ac = (π*36)cm²

Ac = 113.1cm²

A = Ac - As

A = 113.1cm² - 72.1cm²

A = 41cm²

The area of the shaded region is 41cm².

Answer: I can't tell from the photo which is the shaded part. I'll answer on the assumption it is either the square in the circle, or the 4 areas defined by the semicircles outside the square, but inside the circle.

Step-by-step explanation: Note the caveat above.

Circle Area = pi*r^2 or (3.14)*(6cm)^2 = 113.1 cm^2

Area of the square: The 12cm line forms an hypotenuse with either side. The sides are all equal, so if x is 1 side, we can say the area is x^2. We also know tha x^2 + x^2 = 12

x^2 = 6 cm^2 (the area of the square)

The two possible answers:

1) Shaded portion is the square: 6 cm^2

2) Shaded area means the 4 semicircles outside the square but within the circle: 113.1 cm^2 - 6 cm^2 = 107.1 cm^2

Answer:

She is buying 7 bottles and 15 canvases of paint

Step-by-step explanation:

Answer:

7 bottles of paint and 15 canvases

Step-by-step explanation:

I'm letting x stand for the number of bottles of paint and y stand for the number of canvases

1.29x+1.89y=37.38

and y=x+8

Since the y value is isolated I can just substitute the right side of the y= equation into the original like so

1.29x+1.89(x+8)=37.38

I then distributed the 1.89 to each of the terms in the parentheses

1.29x+1.89x+15.12=37.38

I then combined like terms to get

3.18x+15.12=37.38

Then you subtract 15.12 from both sides to get

3.18x=22.26

and last we divide both sides by 3.18 to get

x=7

Now that we have x, we still need to solve for y, so I take the original equation y=x+8 and substitute in the value we solved for x to get

y=7+8

y=15

Answer:

Step-by-step explanation:

3x + x^2 + 2x

= x^2 + 5x

As x goes to negative infinity,

x^2 is always positive and will be higher than  5x as x  increases so

f(x) goes to infinity

Answer:

19y - 9

Step-by-step explanation:

Answer:

As it gets closer to the sun

Step-by-step explanation:

just trust me

The tail of comet will appear to become longer : (c) as it gets closer to sun.

The tail of a comet becomes longer and more pronounced as it gets closer to sun. Comets are made up of ice, dust, and volatile gases. As a comet approaches the sun, the sun's heat causes the ices within the comet to vaporize, creating a glowing coma (a cloud of gas and dust) around the nucleus.

The solar wind and radiation pressure then push the gas and dust particles away from the coma, forming the tail that points away from the sun due to the solar wind's influence. This tail becomes more visible and elongated as the comet gets closer to the sun, making it a sight in night sky.

Therefore, the correct option is (c).

Answer: $2/child and $4/adult

Step-by-step explanation:

The total fare is $14 for 2 adults and 3 children

x is the child's fare

y is the adults fare

We can say:

1)  3x + 2y = $14

2)  We are told that x = (1/2)y  [each child's fare is 1/2 each adult's fare]

3) use (2) in (1)

  3x + 2y = $14

  3(1/2)y + 2y = $14

 (3/2)y + 2y = $14

  (7/2)y = $14

  y = ($14)*(2/7)

  y = $4/adult

   x = (1/2)y; x = (1/2)(4)

   x = $2/child

Check:  Does 3x + 2y = $14 when x = $2/child and y = $4/adult?

    3x + 2y = $14

    3($2/child) + 2($4/adult) = $14

      $6   +   $8 = $14   YES
