The value of the missing length is 20

Let the missing length be x

From Parallel lines and transversal theorem, we have that

If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.

Then, we can write that

$\frac{x}{15} =\frac{16}{12}$

∴ $x = \frac{15\times 16}{12}$

x = 20

Hence, the value of the missing length is 20

PLEASE NO LINKS I LOST SO MANY POINTS

Answer:

We will split the trapezoid into right angle triangle and rectangle

Traingle with base 3cm and height 10 - 6 = 4cm

Area of traingle

= $\frac{1}{2}*base *height = \frac{1}{2} * 3 * 4 = 6cm^{2}$

Area of rectangle with sides 6cm and 3cm

= $6 * 3 = 18cm^{2}$

Therefore, area of the trapezoid

= $6+18 = 24cm^{2}$

Area of the semi circle with radius 3/2 = 1.5cm

= $\frac{1}{2}\pi r^{2} = \frac{1*\pi *1.5*1.5}{2} = 1.125\pi cm^{2}$

$Total area = 24 + 1.125\pi =27.53cm^{2}$

There is 12/15 of a pizza left. How many 3/10 pieces can be made from the leftover pizza? Show work please!

Katyanochek1 [597]

How many 1/3 pieces can be made from 2 pizzas, we know it is 6 and it is arrived by dividing 2 by 1/3 or multiplying by its reciprocal 3/1.

Hence to find how many 3/10 pieces can be made from 12/15 pizza, we have to divide 12/15 by 3/10 or multiplying by its reciprocal 10/3, i.e.

12/15 times 10/3= 8/3 or 2 2/3

What does that mean? This means that while 2 three-tenths pieces can be made, 2/3of 3/10 i.e. <span>2/3×3/10=2/10=1/5</span> or one-fifth of pizza will be left out.

So the answer is 2 three-tenths pieces can be made, and one-fifth pizza will be left out.

Answer:

The % growth rate is 15.8%.

Step-by-step explanation:

Let the function is given by $f(w) = a(b)^{w}$ , where f(w) is the number of a specific product produced after w weeks.

Now, given for w = 0, f(0) = 190 = a

So, the function becomes $f(w) = 190(b)^{w}$ ............. (1)

Now, it is also give that at w = 1, f(1) = 220.

So, from equation (1) we get,

$220 = 190 (b)^{1} = 190b$

⇒ b = 1.15789.

Now, b = 1 + r

⇒ 1.15789 = 1 + r

⇒ r = 0.15789

Therefore, the % growth rate is 0.15789 × 100% = 15.8% (Approx.)

When does the proportion form of newton's second law take the form of an equation?

Brrunno [24]

Newton's law of motion has three parts. The second of which states that the force needed to move an object is directly proportional to the acceleration of the motion. The proportion can be written as,
F = ka
where k is the constant of proportionality. This can be substituted with the mass of the object such that the equation would become.
F = ma
where F is force, m is mass, and a is acceleration.
