The height of a triangle is 3cm less than the length of its base and is area is 27m,find the height
Shkiper50 [21]
Area of a triangle=bh/2

27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0

x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.

Final answer: Height=6 m

what is the answer to the volleyball team at blue point high school has saved $680 and the team plans to spend no more then that
zloy xaker [14]

Answer:

6 x + 23 y  < $ 680  represents the combinations of x balls and y nets that can be purchased.

Step-by-step explanation:

The number of balls than can be purchased  = x

The number of nets than can be purchased  = y

Total savings  = $ 680

Now, the cost of 1 ball =$6

So, the cost of x balls = x ( cost of 1 ball) = x ( $6)  = 6 x

Also, the cost of 1 net =$23

So, the cost of y nets = y ( cost of 1 net = y ( $23)  = 23 y

So, the total amount spent on x balls  and y nets

= Amount spent on x balls + Amount on y nets

=  6 x + 23 y

Also, the saved amount is $680

⇒<u> 6 x + 23 y  < $ 680</u>

Hence, 6 x + 23 y  < $ 680  represents the combinations of x balls and y nets that can be purchased.

Solve the equation: 5/6 = 1/3 + D
Sauron [17]
Answer: \frac{1}{2} 
 
Explanation:
\frac{5}{6} =  \frac{1}{3}  + D 
\frac{5}{6}  -  \frac{1}{3} = \frac{1}{3}  -  \frac{1}{3} + D 
\frac{5}{6} -  \frac{1}{3} = D 
\frac{5}{6} - 2(\frac{1}{3}) = D
\frac{5}{6} - \frac{2}{6} = D 
\frac{3}{6} = D = \frac{1}{2}
