Answer:

  • A: 13 1/3 days
  • B: 40 days

Step-by-step explanation:

If person A can paint the house in 'a' days, then person B takes 3a days. Each day, the total amount of house painted when they work together is ...

  1/a + 1/(3a) = 1/10

  4/(3a) = 1/10 . . . combine terms

  40 = 3a . . . . . . . cross multiply

  a = 40/3 = 13 1/3 . . . . . divide by 3

A can paint the house in 13 1/3 days.

B can paint the house in 40 days.

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?
Llana [10]

Formula for the volume of cone is \frac{1}{3} \pi r^2h

Where r= radius of the cone

h = height of the cone

The value of pi is 3.14

Given volume of larger cone is 131 cm^3

Volume of larger cone = \frac{1}{3} \pi r^2h

131 = \frac{1}{3} \pi 5^2h

Solve for h

131 = 26.1667 *h

So h= 5 cm

The height of bigger cone = 5cm

Now we find the volume of smaller cone

Two cones similar so the sides are in proportional

\frac{radius(small)}{radius(large)}=  \frac{height(small)}{height(large)}

\frac{2}{5} =\frac{ height of small}{5}

Height of smaller cone = 2cm

volume of smaller cone = \frac{1}{3} \pi 2^2*2

= 8.38cm^3

How much is the difference in yearly median income for a female versus male at a masters degree level?
ale4655 [162]

Answer: the difference in yearly median income for a female vs male at a masters degree level is

$15,642.90/year

Step-by-step explanation:

there are roughly 52.143 week in a year.

the median weekly income for a female with a masters degree is : $901.00

the median weekly income for a male with a masters degree is :

$1,201

so if you multiply $901 x 52.143 you get :

$46,980.84, which is what a female makes in a year with a md

and if you multiply $1,201 x 52.143 you get :

$62,623.74, which is what a male makes in a year with a md

subtract $62,623.74 - $46,980.84 you get :

$15,642.90 / year
