Answer:
70
Step-by-step explanation:
2 quarters are 50¢
4 dimes are 40¢
1 nickel is 5¢
if you add it all together you will get 70¢
Profit = revenue (income) - expenses
profit = 189 - 27
profit = 162 <==
H=x and b=x+10
A=hb/2 so
A=x(x+10)/2
A=(x^2+10x)/2 and A=48 so
(x^2+10x)=96
x^2+10x-96-0
x^2-6x+16x-96=0
x(x-6)+16(x-6)=0
(x+16)(x-6)=0, since x>0
x=6in, and since the base is x+10
base=16in
Given:
Surface area = 4,362 yards
Length = 36 yard
Width = 21 yard
Height = c
To find:
Volume of the rectangular prism.
Solution:
Surface area formula:
Substitute the given values.
Subtract 1512 from both sides.
Divide by 114 on both sides, we get
25 = c
Height = 25
Volume = length × breadth × height
= 36 × 21 × 25
= 18900
Volume of rectangular prism is 18900 cubic yards.
Answer:
2x^2 / (3x-1)(x-2)
Step-by-step explanation:
You can simplify any rational expression (fraction/fraction) or (fraction/number) or
(number/fraction) or even (number/number) by using
KEEP-CHANGE-FLIP
KEEP the first fraction (or the one on top), CHANGE the ÷ to times. FLIP over the last fraction (or bottom expression) see image.
Keep the x/3x-1 the same, change to multiplication. Flip over the second term to be 2x / x-2.
To multiply, you multiply straight across: top×top and bottom×bottom. See image.
(the very small final answer is just in case you are expected to multiply out the denominator. I think the factored form is neater. See image.
