Answer:

C. j +2j + 3(2j) = 175

Step-by-step explanation:

Let j represent the amount of money Jim has.

Carroll has twice that amount, so has 2j.

Mike has 3 times the amount Carroll has, so has 3(2j).

The sum of these quantities is 175, so the equation can be written ...

j + 2j + 3(2j) = 175 . . . . . matches choice C

If (a+10) and (a+20)are supplementary angles,find them

motikmotik

Given:

(a+10) and (a+20) are supplementary

To find:

Each angle

Steps:

if 2 angles are supplementary that means they add up to 180°

(a + 10) + (a + 20) = 180

a + 10 + a + 20 = 180

2a + 30 = 180

2a = 180 - 30

2a = 150

a = 150/2

a = 75°

Now let's find value of each angle,

a + 10 = 75 + 10

= 85°

a + 20 = 75 + 20

= 95°

Therefore, the value of each angle is 85° and 95° respectively

Happy to help :)

Find the total surface area.

Ede4ka [16]

Hey love! <3

Answer:

The right answer is A = 49.6 π ft^2

Step-by-step explanation:

(Let pi = 3.1415926535898)

The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2

So if r = 4 ft

and h = 2.2 ft

A= 2π(4)(2.2)+2π(4)^2

Once we've plugged in our formulas our final surface area is A = 49.6 π ft2

Hope this helped you calculate the surface area! ◃┆◉◡◉┆▷ Sincerely, Kelsey from Brainly.

HELP ASAP : Find the largest value of n such that 5x^2+nx+48 can be factored as the product of two linear factors with integer c

Anna71 [15]

Answer:

$n=241$

Step-by-step explanation:

We are given

$5x^2+nx+48$

Let's assume it can be factored as

$5x^2+nx+48=(5x-s)(x-r)$

now, we can multiply right side

and then we can compare it

$5x^2+nx+48=5x^2-5rx-sx+rs$

$5x^2+nx+48=5x^2-(5r+s)x+rs$

now, we can compare coefficients

$rs=48$

$5r+s=-n$

$n=-(5r+s)$

now, we can find all possible factors of 48

and then we can assume possible prime factors of 48

$48=-+(1\times 48)$

$48=-+(2\times 24)$

$48=-+(3\times 16)$

$48=-+(4\times 12)$

$48=-+(6\times 8)$

Since, we have to find the largest value of n

So, we will get consider larger value of r because of 5r

and because n is negative of 5r+s

so, we will both n and r as negative

So, we can assume

r=-48 and s=-1

so, we get

$n=-(5\times -48-1)$

$n=241$
