Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

A p

Step-by-step explanation:

We have

$12x {}^{ - 3} y {}^{ - 1}$

Remeber that

$x {}^{ - n} = \frac{1}{x {}^{n} }$

$12 \frac{1}{x {}^{3} } \frac{1}{y {}^{1} }$

Now, plug in

So now we plug in -1 for x and 5 for y

$12 \frac{1}{ { - 1}^{3} } \frac{1}{5 {}^{1} }$

Simplify

$- \frac{12}{5}$

A is the answer.

The initial point of a⃗ is (−2,4), and its terminal point is (−5,−2). What is the value of ‖a⃗ ‖? Give your answer as a simplifi

lyudmila [28]

Answer:

$3\sqrt{5}.$

Step-by-step explanation:

It is given that the initial point of $\vec{a}$ is (-2,4) and terminal point is (-5,-2). So, $\vec{a}$ is defined as

$\vec{a}=(-5-(-2))\hat{i}+(-2-4)\hat{j}$

$\vec{a}=(-5+2)\hat{i}+(-2-4)\hat{j}$

$\vec{a}=-3\hat{i}-6\hat{j}$

The magnitude of $\vec{v}=a\hat{i}+b\hat{j}$ is

$|\vec{v}|=\sqrt{a^2+b^2}$

The magnitude of $\vec{a}$ is

$|\vec{a}|=\sqrt{(-3)^2+(-6)^2}$

$|\vec{a}|=\sqrt{9+36}$

$|\vec{a}|=\sqrt{45}$

$|\vec{a}|=3\sqrt{5}$

Modulus of magnitude is

$||\vec{a}||=|3\sqrt{5}|=3\sqrt{5}$

So, the magnitude of $\vec{a}$ is $3\sqrt{5}.$

3/4 x 2/3 as a fraction

svet-max [94.6K]

Answer:

Hi, There!

Your Answer is $\frac{6}{12} ~or~\frac{1}{2}$

Step-by-step explanation:

$\frac{3}{4} ~x~\frac{2}{3} = \frac{3 ~x~2}{4~x~3}$

Which Equals

$\frac{6}{12}$

Now if you dived the numerator and denominator by 6 you Get...

$\frac{1}{2}$

Therefore, I hope this helps!

Take Care!

A swimming pool is being filled at a rate of 12 cubic feet per minute. If the pool is 18 yards long, 10 yards wide, and 3 yards

MakcuM [25]

12 cubic yards/minute = volume/time

Find the volume by multiplying width, height and length 
Volume = 18*10*3 = 540 cubic yards 

Back to original equation: 
12 = 540/time 
time = 540/12 

time = 45 minutes
