The answer is 40

you go up what ever it equals so like

1+4=5 but 2+5=12 that does not make sense but wait

1+4=5 5+5+2=12 12+6+3=21 and 21+8+11=40

In the figure below, one side of the right triangle is a diameter of the semicircle.

olga55 [171]

Answer:

Option (A)

Step-by-step explanation:

One side of the given triangle is a diameter of the semicircle given.

Measure of the diameter = 10 units

Total area of the semicircle = $\frac{1}{2}\pi (r^{2})$

= $\frac{1}{2}\pi (5)^2$

= 39.27 square units

Area of the right triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(6)(8)$

= 24 square units

Area of the shaded region = Area of the semicircle - Area of the right triangle

= 39.27 - 24

= 15.27 square units

≈ 15 square units

Therefore, option (A) will be the answer.

Soloha48 [4]

Answer: 10

Step-by-step explanation:

1. Write the fractions as 2/9 times 45/1.

2. Cross cancel 45 and 9 by dividing by 5, which now gives you 2/1 and 5/1.

3. Multiply 2/1 and 5/1 and you get 10.

From Andys house to Billys hometown you can travel by 3 roads. And to get from Billys hometown to Willies's house you can travel

Rom4ik [11]

Andy to get to Willie's house = 15 ways

Andy to get to Willie's house = 45 ways

<h3>How to determine the ways</h3>

From the information given, we have that from

Andy's house to Billy's hometown = 3 roads

Billy's hometown to Willies house = 5 ways

To travel from Andy's house to Willies house, we should multiply the number of ways

= 3 × 5

= 15 ways

Dan's ranch to Andy's house = 1 road

To Willie's house = 2 roads

For Andy to get to Willie's house, we have;

= 3 × 15

= 45 ways

If Vector u=(5,-7) and v=(-11,3), 2v-6u=_____ and ||2v-6u||≈_____

Sauron [17]

<h2>Answer:</h2>

$2\vec{v}-6\vec{u}=(-52,48) \\ \\ ||2\vec{v}-6\vec{u}||=75.28}$

<h2>Step-by-step explanation:</h2>

In this problem we have two vectors:

$\vec{u}=(5,-7) \ and \ \vec{v}=(-11,3)$

So we need to find two things:

$2\vec{v}-6\vec{u}$

and:

$||2\vec{v}-6\vec{u}||$

FIRST:

In this case we have the multiplication of vectors by scalars. A scalar is a simple number, so:

$2\vec{v}-6\vec{u} \\ \\ Replace \ \vec{v} \ and \ \vec{u} \ by \ the \ given \ vectors: \\ \\ 2(-11,3)-6(5,-7) \\ \\ Multiply \ each \ component \ by \ the \ corresponding \ scalar:\\ \\ (2\times (-11),2\times 3)+(-6\times 5,-6\times (-7)) \\ \\ (-22,6)+(-30,42) \\ \\ Sum \ of \ vectors: \\ \\ (-22-30,6+42) \\ \\ \therefore \boxed{(-52,48)}$

SECOND:

If we name:

$\vec{w}=2\vec{v}-6\vec{u}$

Then, $||2\vec{v}-6\vec{u}||$ is the magnitude of the vector $\vec{w}$ . Therefore:

$||\vec{w}||=||2\vec{v}-6\vec{u}|| \\ \\ ||\vec{w}||=||(-52,48)|| \\ \\ ||\vec{w}||=\sqrt{(-58)^2+48^2} \\ \\ ||\vec{w}||=\sqrt{3364+2304} \\ \\ ||\vec{w}||=\sqrt{5668} \\ \\ \boxed{||\vec{w}||=75.28}$
