Ellie has 30 total toys and she divides them in 5 rows. How many toys did she divide into 5 rows to make it a total to 30?




sorry if it doesn't sound right.

Answer:

[tex]\frac{\sqrt{21} }{5}[/tex]

Step-by-step explanation:

Given

cosθ = - [tex]\frac{2}{5}[/tex]

Using the identity

sin²θ + cos²θ = 1 , then

sinθ = ± [tex]\sqrt{1-cos^20}[/tex]

       = ± [tex]\sqrt{1-(-\frac{2}{5})^2 }[/tex]

      = ± [tex]\sqrt{1-\frac{4}{25} }[/tex]

      = ± [tex]\sqrt{\frac{21}{25} }[/tex]

     = ± [tex]\frac{\sqrt{21} }{5}[/tex]

Since θ is in second quadrant the sinθ > 0 , thus

sinθ = [tex]\frac{\sqrt{21} }{5}[/tex]

Answer:

the elevation of the entrance is -21

Step-by-step explanation:

The computation of the elevation of the entrance is shown below;

-15 = -1 + 2 ÷ 3e

e = -21

Hence, the elevation of the entrance is -21

We simply applied the above equation so that we can determine the elevation of the entrance

Answer:

-3

Step-by-step explanation:

Divide through the equation by the leading coefficient to obtain:

y+3x-4=0

y=4-3x

and our gradient is -3

Answer:

$31.88

Step-by-step explanation:

Given

Consumer charges = 2530.16cents

Consumer charges in dollars = $25.3016

Interest rate per day = 0.042%

Interest gotten per day = 0.042×25.3016

Interest per day = $1.06266

Interest in 30 days = ,30×1.06266

Interest in 30 days = $31.88

Answer:

41.5

Step-by-step explanation:

you use the trigonometric equations. in this case, we will use SOH:

sin 49=opposite/adjacent

sin 49=x/55

55 sin 49=x

41.50=x

Therefore, x is equals to 41.50. And it is already to it's nearest hundredth.

The value of x is  41.25.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

We use the sin function.

Sin 49 = DE/DF

Sin 49 = x / 55

0.75 = x / 55

x = 0.75 x 55

x = 41.25

Thus,

The value of x is  41.25.

Answer:

15.6 inches

Step-by-step explanation:

Here we want to find the length of the missing side

Mathematically, we can use Pythagoras’ theorem

The theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Let the missing side be x

18 is the side that faces right angle and this is the hypotenuse

Thus, we have ;

x^2 + 9^2 = 18^2

x^2 = 324 - 81

x^2 = 243

x = √(243)

x = 15.6 in

The value of x assuming e that segments that appear to be tangent are tangent is 8

The triangle inside the circle is right angles since the side length "x" is tangential to the circle.

To determine the value of "x", we will use the Pythagorean theorem as shown:

17^2 = x^2 + 15^2

289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64

x = 8

Hence the value of x assuming e that segments that appear to be tangent are tangent is 8
