How would I write Doubling the quantity of a number decreased by six is less than negative thirty-six

Answers

Answer 1

Answer: quantity of a number is represented by x
doubling x means 2 times x or 2x
decreased by 6 means minus 6 or 2x-6
is less than means <
negative 36 means -36

2x-6<-36
add 6
2x<-30
divide 2
x<15

Find the values of (x) for which the ball's height is 27
feet.
height (h)= 7+37x-16x^2

Answers

sett is to 27
27=7+37x-16x^2
multiply -1 both sides
-27=-7-37x+16x^2
add 27 both sides
16x^2-37x+20=0
use quadratic equation
if yo have
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}$

1=16
b=-37
c=20

x= $\frac{-(-37)+/- \sqrt{(-37)^(2)-4(16)(20)} }{2(16)}$
x= $(37+/- √(1369-1280) )/(32)$
x= $(37+/- √(89) )/(32)$
aprox
x=0.861438 or 1.45106

Sally earns graduated commission on her sales each month. She earns 6% commission on the first $45,000 in sales and 8% on anything over that. If Sally had $51,000 in sales this month, how much commission did she earn?

Answers

Sally earns commission depending on her sales per month.She said to be earning 6% for the first 45 000 dollars in her sales.Now, she will be receiveing another 8% on anything that is over the said sales.Given that Sally were able to reach 51 000 dollars sales.Let's find how much is her total commission:=> 45 000 dollars * .06 = 2700 dollars=> 51 000 dollars - 45 000 dollars = 6 000 dollars=> 6 000 dollars * .06 = 360 dollars=> 2 700 dollars + 360 = 3060 dollars.

Step-by-step explanation:

An automobile engineer is redesigning a conical chamber that was originally specified to be 12 inches long with a circular base of diameter 5.7 inches. In the new design, the chamber is scaled by a factor of 1.5. The volume of the original chamber is a.)102.02 b.)248.04 c.)306.06 d.)412.08 cubic inches. This is a.)242.47 b.)344.49 c.)432.16 d.)448.21 cubic inches less than the volume of the new chamber.

Answers

The answers are:
a.)102.02
a.)242.47

The volume of the cone can be expressed as:
$V = (1)/(3) \pi r^(2) h$
where:
V - the volume of the cone,
r - the radius of the cone,
h - the height of the cone.

It is given:
h = 12 in
R = 2r = 5.7 in ⇒ r = 5.7 in ÷ 2 = 2.85 in
π = 3.14

Therefore, the volume of the original conical chamber (V₁)
$V = (1)/(3) *3.14*(2.85) ^(2) *12 = 3.14*8.1225*4 = 102.02 in^(3)$

Further, the new chamber is scaled by a factor of 1.5. That means that radius and height of the original chamber are increased 1.5 times:
r₁ = r · 1.5 = 2.85 in · 1.5 = 4.275 in
h₁ = h · 1.5 = 12 in · 1.5 = 18 in

The volume of the new chamber is:
$V_1= (1)/(3) *3.14*(4.275) ^(2) *18 = 3.14*18.28*6=344.49 in ^(3)$

The difference between two chambers is:
V₁ - V = 344.49 - 102.02 = 242.47
