What is 2(W+5)+4W=4(3+W)

1 answer:

8 0

You will need to use the distributive property of multiplication over addition to solve this problem.
2w+10+4w=12+w
combine like terms using the associative property
6w+10=12+w
solve the equation
6w+10-10=12-10+w
6w÷6=2+w÷6
w=2+w/6

The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the

Naily [24]

Let r represent the radius of cylinder.

We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be $1.5r$ .

We will use lateral surface area of pyramid to solve our given problem.

$LSA=2\pi r h$ , where,

LSA = Lateral surface area of pyramid,

r = Radius,

h = height.

Upon substituting our given values in above formula, we will get:

$LSA=2\pi r\cdot (1.5)r$

Now we will find the total surface area of cylinder.

$TSA=2\pi r(r+h)$

$TSA=2\pi r(r+1.5r)$

$TSA=2\pi r(2.5r)$

$\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}$

$\frac{TSA}{LSA}=\frac{2.5r}{1.5r}$

$\frac{TSA}{LSA}=\frac{25}{15}$

$\frac{TSA}{LSA}=\frac{5}{3}$

Therefore, the ratio of total surface area to lateral surface area is $5:3$ .

solmaris [256]

if indeed two functions are inverse of each other, then their composite will render a result of "x", namely, if g(x) is indeed an inverse of f(x), then

$\bf (g\circ f)(x)=x\implies g(~~f(x)~~)=x \\\\\\ \begin{cases} f(x) = 3x\\ g(x)=\cfrac{1}{3}x \end{cases}\qquad \qquad g(~~f(x)~~)=\cfrac{1}{3}[f(x)]\implies g(~~f(x)~~)=\cfrac{1}{3}(3x)$

Dante has 60 baseball cards. this is at least six more than three time as many cards as Anna. write and solve an inequality to r

Anon25 [30]

D=dante's cards number
a=anna's cards number

d=60
this (d) is at least (smallest is, aka greater than or equal to or >) 6 more than (+6) 3 times as many as anna (3 times a or 3a)

d>6+3a
d=60
60>6+3a
subtract 6 from both sides
54>3a
divide both sides by 3
18>a
anna has at least 18 cards
