Y varies directly with x. If y=40 when x=16, find x when y= -5

Answer:

[tex]10v^2-17v+3[/tex]

Step-by-step explanation:

To find the equivalent of this expression we have to use the FOIL method

So you multiply the first terms [tex]2v*5v[/tex]

Then multiply the outer terms [tex]2v*-1[/tex]

Then multiply the inner terms [tex]-3*5v[/tex]

Then multiply the last terms [tex]-3*-1[/tex]

Answer:

Step-by-step explanation:

- 38d - 57 ≥ - 19d + 76

- 38d + 38d - 57 - 76 ≥ - 19d + 38d + 76 - 76

-133 ≥ 19d

-133/19 ≥ 19/19d

-7 ≥ d

Answer:

[tex]d\leq -7[/tex]

Step-by-step explanation:

Move all terms containing [tex]d[/tex] to the left side of the inequality.

Add [tex]-19d[/tex] to both sides of the inequality.

[tex]-38d-57+19d\geq 76[/tex]

Add [tex]-38[/tex] and [tex]19d.[/tex]

Move all terms not containing  [tex]d[/tex]  to the right side of the inequality.

Add [tex]57[/tex] to both sides of the inequality.

[tex]-19d\geq 76+57[/tex]

Add [tex]76[/tex] and [tex]57.[/tex]

[tex]-19d\geq 133[/tex]

Divide each term by [tex]-19[/tex] and simplify.

Divide each term in [tex]-19d\geq 133[/tex] by [tex]-19[/tex]. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

[tex]\frac{-19d}{-19} \leq \frac{133}{-19}[/tex]

Cancel the common factor

[tex]\leq \frac{133}{-19}[/tex]

Divide [tex]133[/tex] by [tex]-19.[/tex]

[tex]d\leq -7[/tex]

The result can be shown in multiple forms.

Inequality Form:

[tex]d\leq -7[/tex]

Uisng the ratio concept, the number of charms that should be put into each group would be 12 and 18 respectively

Given the Parameters :

The group with 2 :

[2 ÷ (2+3)] × 30

(2 / 5) × 30

= 12

The group with 3 :

[3 ÷ (2+3)] × 30

(3 / 5) × 30

= 18

Hence, each group will have 12 and 18 charms respectively

Radius = 7cm , Circumference = 43.96cm

Step-by-step explanation:

To find the radius, you divide the diameter by 2.

14 / 2 = 7cm

To find the circumference, you multiply 兀 ( 3.14 ) with the diameter

兀d = 兀 x 14 = 43.96cm

Answer:

The third one

Step-by-step explanation:

Answer:

-24 does not equal 0, so therefore there's no solution.

Step-by-step explanation:

In order to get x by its self, you first have to subtract 6x on both sides to get -24 = 0. Next divide 12 on both sides to get -2 = x.

Hope this helps you :)

Using implicit differentiation, it is found that she must blow air at a rate of 251.33 cm³/sec.

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

The radius is half the diameter, hence:

[tex]r = \frac{d}{2}[/tex]

[tex]r^3 = \frac{d^3}{8}[/tex]

[tex]V = \frac{4\pi d^3}{24} = \frac{\pi d^3}{6}[/tex]

Applying implicit differentiation, the rate of change of the volume is:

[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]

The rate that she must blow air is:

[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]

[tex]\frac{dV}{dt} = \frac{4^2 \pi}{2}(10)[/tex]

[tex]\frac{dV}{dt} = 251.33[/tex]

She must blow air at a rate of 251.33 cm³/sec.

Answer:

1/8

Step-by-step explanation:

x-8y=-1

First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)

-8y = -x-1

y = 1/8x +1/8

The slope is 1/8 and the y intercept is 1/8

The slope for parallel lines is the same for all parallel lines

1/8

-2-2=0.5(3-5)

OR (-2-2)=1/2(3-5)

Step-by-step explanation:

m∠2 = m∠4

y + 10 = 3y - 24

y - 3y = -24 - 10

-2y = -34

y = -34/-2

y = 17

m∠2 = y + 10

m∠2 = 17 + 10

m∠2 = 27°

Answer:

Step-by-step explanation:

Let width = w

Length = w - 7

Perimeter = 2*(length + width)

2*(w-7 + w) = 50

2* (2w - 7) = 50

2*2w - 7*2 = 50

4w - 14 = 50

Add 14 to both the sides

4w = 50+ 14

4w = 64

Divide the entire equation by  4

w = 64/4

w = 16 units

Length = 16 - 7 = 9 units
