The brand new team operates at a speed of 1/12 apt/hr.
On the other hand, the experienced team functions at a pace of 1/6 apt/hr.

Let x represent the time taken to paint the apartment when both teams collaborate.

Thus, 
(1/12 + 1/6 apt/hr)*(x hr) = (1 apt)
(3/12)x = 1
(1/4)x = 1
x = 4 hours

Answer: 4 hours

Logan can read at a rate of 2/3 page per minute. At that rate, how many pages can he read in 2 hours?
Inessa [12570]

Response:

240- 360

Step-by-step breakdown:

First, determine how many minutes are in an hour, which is 60. Multiply that by 2 to find the total for 2 hours, resulting in 120 minutes. Next, you calculate the total for 2 hours by multiplying 2 by 120, yielding 240. Then, multiply 3 by 120 for a total of 360.

I'm unsure if this answer is accurate, but that's my approach.:)

The gravitational force between Pluto and Charon is 3.61 × 1018 N. Pluto has a mass of 1.3 × 1022 kg, which is only slightly gre
lawyer [12517]
The formula for gravitational force is F = G * m1 * m2 / r². The gravitational constant is G = 6.67 * 10^(-11) m³/kgs². Thus, we find r = sqrt(G * m1 * m2 / F) = sqrt(6.67 * 10^(-11) m³/kgs² * 1.3 * 10^(22) kg * 1.6 * 10^(21) / 3.61 * 10^(18) N) = sqrt(3.84 * 10^(14)) = 1.96 * 10^(7) m, which is approximately 2 * 10^(7) m.

A survey conducted five years ago by the health center at a university showed that 18% of the students smoked at the time. This
tester [12383]
The test statistic (Z) is 2.5767, and the p-value of the test is 0.009975. The null hypothesis suggests that the smoking rate among students has not changed, while the alternative indicates otherwise. The z-statistic for the sampled proportion is computed, yielding z ≈ 2.5767. As we investigate whether the smoking percentage has shifted over the preceding five years, the two-tailed p-value is found to be 0.009975. This result is significant at a 99% confidence level, demonstrating substantial evidence that the percentage of smoking students has changed.

A. Given directed line segment MN with M(-6,-2) and N(3,1), find point P that partitions the segment into a ratio of 1:2. Explai
AnnZ [12381]

1. According to the definition, a specific point that splits a line segment into a ratio of a:b is indicated by the following x-coordinate:

x1+\frac{a}{a+b} (x2-x1)

And the y-coordinate:

y1+\frac{a}{a+b}(y2-y1)

2. Keeping this in mind, you have:

A) x-coordinate:

-6+(\frac{1}{1+2}) (3+6)=-3

y-coordinate:

-2+(\frac{1}{1+2} )(1+2)=-1

The answer is: P(-3,-1)

B) The x-coordinate is:

-1+(\frac{3}{3+1} )(3+1)=2

The y-coordinate is:

6+(\frac{3}{3+1} )(-2-6)=0

The answer is: L(2,0)

The sum of 48 and itself its half and half of the hal is added to 18​
babunello [11817]

Answer:

150

Step-by-step explanation:

We perform addition.

a) The total of 48 added to itself

= 48 + 48 = 96

b) Its half plus half of the half

= 96 + (1/2 × 48) + (1/2 × (1/2 × 48)

= 96 + 24 + (1/2 × 24)

= 96 + 24 + 12

= 132

c) plus 18

= 132 + 18

= 150

Thus, adding 48 to itself, its half, and half of that to 18 results in 150.
