myrzilka [38]

Answer:

The revised drawing be larger or smaller than your original one

Step-by-step explanation:

The revised drawing be larger or smaller than your original one.

Because a drawing at a scale of:

1:10 means that the object is 10 times smaller than in real life scale 1:1

1: 8 means that the object is 8 times smaller than in real life scale 1:1

So it means the revised drawing be larger or smaller than your original one

Question 5

Temka [501]

Answer:

$B = \frac{31.5}{5.25}= 6$

$H = 18-6= 12$

So then Mark purchased 12 Hamburgers and 6 packages of buns

Step-by-step explanation:

For this case we can define the following notation:

B represent the number of packages buns

H represent the number of hamburgers

And from the information given we can set up the conditions into the following equations:

$6.75 H +1.50 B =90$ (1) represent the total cost

$H +B =18$ (2) represent the total number of items

Solving H from equation (2) we got:

$H = 18 -B$ (3)

And replacing equation (3) into equation (1) we got:

$6.75 (18-B) +1.5 B =90$

And dsitributing the terms we have:

$121.5 -6.75 B +1.5 B =90$

And solving for B we got:

$121.5-90 = 5.25 B$

And dividing by 5.25 we got:

$B = \frac{31.5}{5.25}= 6$

And replacing the value of B into equation (3) we got:

$H = 18-6= 12$

So then Mark purchased 12 Hamburgers and 6 packages of buns

Find the exact value by using a half-angle identity.<br><br> tan seven pi divided by eight

murzikaleks [220]

9514 1404 393

Answer:

1 -√2

Step-by-step explanation:

$\tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}$

tan(7π/8) = 1 -√2
