Answer:

60

Step-by-step explanation:

He needs to write 300*9 pages which is 2700

We know that he writes 45 pages a minute

his speed can be shown through the following equations

45x=pages typed

where x=minutes

so we set up our problem

45x=2700

we divide by 45 and get x=60

Tan 45=√2/n

n=√2

again

sin 45=√2/m

m=2

answer:<u> </u><u>m</u><u>=</u><u>2</u><u>,</u><u>n</u><u>=</u><u>√</u><u>2</u>

<u>2</u><u>.</u>

sin 45=x/3

x=3/√2=3√2/2

y=3√2/2

<u>a</u><u>n</u><u>s</u><u>:</u><u>x</u><u>=</u><u>3√2/2</u><u>,</u><u>y</u><u>=</u><u>3√2/</u><u>3</u>

What equation represents the line that passes through the points(6,-3) and (-4,-9)?
marysya [2.9K]
M = - 3 + 9 / 6 + 4
m = 6 / 10
m = 3/5

- 3 = 3/5 ( 6 ) + c
- 15 = 18 + 5c
5c = - 33
c = - 33/5
y = 3/5x - 33/5

14a - (2a +9)=2/3 (12a-18)​
Dmitrij [34]

Answer: a=-0.75

Step-by-step explanation:

14a - (2a +9)=2/3 (12a-18)​

14a - 2a -9=2/3 * 6(2a-3)​

12a-9=2*6/3 (2a-3)​

12a-9=2*2(2a-3)​

12a-9=4(2a-3)​

12a-9=8a-12

4a-9=-12

4a=-3

a=-3/4

a=-0.75
