Answer:

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13     x = 13

   cos45 = 13/y     y = 13√2

12) sin30 = 4/x      x = 8

     tan30 = 4/y     y = 4√3

13) sin60 = 21/x    x = 21(2/√3) = 42/√3

    y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22   x = 22/√2

     sin45 = y/22   y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x   x = 12/√2

tan45 = y/12      y = 12

cos30 = z/24    z = 24(√(3)/2) = 12/√3

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

  To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag) 
5/25 x 100% (because you're trying to find probability of red) 
= 20% 

2) 5 + 8 = 13 (# of red AND blue) 
13/25 x 100% (divide out of the total) 
=52% 

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green) 
0.2 x 0.48 x 100% 
= 9.6% 

4) 10 + 12 + 28 = 50 (to find total number of trials) 
28/50 x 100% 
= 56% 

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner) 
= 35</span><span>Its B 20%

In February, Campus Cycle Repair had income from sales of $16,000. Expenses for the month included: rent, $1,250; utilities, $45
djyliett [7]

Answer:

Profit $5700

Step-by-step explanation:

To find loss/profit you subtract the expenses from the total income

Income from sales= $16000

Franchise fee= 5% of sales income

=\frac{5}{100} *16000=800

Rent=$1250

Utilities=$450

Wages=$4800

insurance=$300

supplies=$2700

Total expenses

=$1250+$450+$4800+$300+$2700+$800=$10300

Total income

=$16000

Profit

=$16000-$10300=$5700

Which of the following equations represents the greatest value of x?
jonny [76]
Hey mate!
You stuck?

^3 The cube root of 125=5
^2 The square root of 35=5.91
^3 The cube root of 64=4
^2 The square root of 38=6.16

Therefore your answer would be x2= 38, because 6.16 is greater than the other sums.



Hope this helps! :) (Don't forget Brainliest) :)
