The president of a certain university receives a salary that is four times the salary of one of the department heads. The total

Viktor [21]

a. The salary of the department head is $105,000.

b. The salary of president is $420,000.

Step-by-step explanation:

Let,

x be the salary of president.

y be the salary of head of department.

According to given statement;

x=4y

a) What is the salary of the department head?

Salaries of two heads of department = $210000

$2y=210000$

Dividing both sides by 2;

$\frac{2y}{2}=\frac{210000}{2}\\y=105000$

The salary of the department head is $105,000.

b) What is the salary of the president of the university?

x=4y

$x=4(105000)\\x=420000$

The salary of president is $420,000.

Someone help me I will give a brainlist to whoever explains how to figure out the answer

ziro4ka [17]

Answer: see work

Step-by-step explanation:

Total area is 24x22=528

one circle area is (pi)3^2=9(pi)

that times 4 because of 4 circles =36(pi)

so the total are minus the circles now

in terms of pi the answer is 528-36(pi)

if pi = 3.14 the answer in 414.96

If the sin 60 agrees equals the square root of three over two which statement is true

torisob [31]

Given that
$\sin60^o= \frac{ \sqrt{3} }{2}$

$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,

$\cos 120^o =-\sin(180-120)^o=-\sin60^o=-\frac{ \sqrt{3} }{2}$ ,

$\cos30^o\neq0$ ,

$\cos120^o\neq0$

Therefore, the true statement is
$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,
because the cosine and sine are complements.

What do you need to subtract from 77/10 to make 7

ycow [4]

70/10= 7

So,

77/10-70/10= 7/10

You need to subtract 7/10 from 77/10 to make 7.

I hope this helps!
