Harold has 2384 g of zinc for his science experiment how many kilograms of zinc does he have? PLEASE HELP I AM TAKING OVERDUE HOMEWORK

Answer:

Obtuse.

Step-by-step explanation:

If we have a vector v = (a, b, c)

The magnitude of the vector is:

|v| = √(a^2 + b^2 + c^2)

And the dot product of two vectors:

v = (a, b, c)

w = (c, d, e)

is:

v.w = |v|*|w|*cos(θ) = a*c + b*d + c*e

With that relation, we can find the angle between the two vectors.

In this case, we have:

v = ⟨−1,0,1⟩

then:

|v| = √( (-1)^2 + 0^2 + 1^2) = √2

And:

w = ⟨4,5,2⟩

then:

|w| = √( 4^2 + 5^2 +2^2) = √116

Then:

v.w = (√2)*(√116)*cos(θ) =  (-1)*(4) + 0*5 + 1*2

(√2)*(√116)*cos(θ) = -4 + 2 = -2

(15.23)*cos(θ) = -2

cos(θ) = -2/15.23

θ = Acos( -2/15.23) = 97.5°

Then the angle is larger than 90°, so the angle is obtuse.

Answer:

1680 ways

Step-by-step explanation:

By using the formula for permutation, which is nPr=n!/(n-r)!,

8P4=8!/(8-4)!

=8!/4!

=8×7×6×5

=1680

Or if you just want to use the multiplication rule (which is simpler).

8×7×6×5=1680

Answer:

Cada ángulo central tiene una medida de 40°.

Step-by-step explanation:

Un ángulo interno en un polígono regular comprende dos ángulos contiguos de igual medida de dos triángulos contiguos. Si el polígono regular tiene un ángulo interno de 140°, entonces cada triángulo tiene dos ángulos de 70°. El tercer ángulo corresponde al ángulo central. Por Geometría sabemos que la suma de las medidas de los ángulos internos de un triángulo es igual a 180°, entonces tenemos que la medida del ángulo central es:

[tex]\alpha = 180^{\circ} - 70^{\circ} - 70^{\circ}[/tex]

[tex]\alpha = 40^{\circ}[/tex]

Cada ángulo central tiene una medida de 40°.

Answer:

The answer is, 3/11 - 2.12.=1.847

Step-by-step explanation:

In mathematics, a fraction is used to represent a portion of something larger. It represents the whole's equal pieces. The numerator and denominator are the two elements of a fraction. The numerator is the number at the top, and the denominator is the number at the bottom. The numerator specifies the number of equal parts taken, whereas the denominator specifies the total number of equal parts in the total.

5/10, for example, is a fraction.

The numerator is 5 and the denominator is 10.

According to the question:

3/11 - 2.12.

Answer:

Step-by-step explanation:

  rectangle =  8x9 = 72

1/3 0f 72 =  24      (72-24=  48)

1/8 of 48 =6   48-6 =42

red-----24

green-----6

unpainted-----42

24+6+42+=72

The 42 squares are left unpainted.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The area of rectangle =  8 x 9 = 72

One-third of these squares are painted red, 1/8 of the remaining squares are painted green, and the others are left unpainted.

1/3 of 72

1/3 x 72 =  24      

(72-24=  48)

1/8 of 48

1/8 x 48 = 6  

( 48-6 =42)

So,

red = 24

green = 6

unpainted = 42

The 42 squares are left unpainted.

Step-by-step explanation:

10 % each month is $12.00 12 months in a year 12 x 12.00 = $144.00

The inequality to describe the total amount Samantha saves is s > 15.

The correct option is (A).

Inequalities are mathematical formulas in which neither side is equal. We compare two values in inequality.

As per the given data:

We are given that Samantha saves at least 10% of her monthly salary.

Samantha is earning $150 each month for a year.

To find the amount Samantha at least saves in a month:

= 10% of her monthly salary

= 10% × 150

= 10/100 × 150

= 15 dollars

As she is saving, at least 15 dollars, then the inequality to describe her savings is as follows:

savings > 15

The inequality to describe the total amount Samantha saves is s > 15.

Hence, The inequality to describe the total amount Samantha saves is

s > 15.
