Andrew jogs 25 5/6 kilometers a week. Yen jogs 13 3/4 kilometers a week. What is the total distance they jog in a week?

Answers

Answer: 39 7/12km

Step-by-step explanation:

From the question, we are informed that Andrew jogs 25 5/6 kilometers a week while Yen jogs 13 3/4 kilometers a week.

The total distance they jog in a week will be the addition of the distance that each person jogged. This will be:

= 25 5/6 + 13 3/4

= 25 10/12 + 13 9/12

= 38 19/12

= 38 + 1 7/12

= 39 7/12

The total Distance covered by both of them is 39 7/12 kilometers

New Orleans averages 77% humidity in the mornings, but it decreases by 20% in the afternoon. What is the average relative humidity in the afternoon in New Orleans? (enter a percent rounded to the tenths place)

Answers

Answer: 61.6%

Step-by-step explanation:

The afternoon humidity average is 20% of the morning average.

The morning average is 77% so the afternoon average must be:

= Morning average * ( 1 - percentage decrease)

= 77% * (1 - 20%)

= 77% * 80%

= 61.6%

Rewrite the following equation in slope-intercept form.
y + 3 = }(x + 6)
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

Slope-intercept form is

y = mx + b

We want to get the y by itself on one side of the equation.

0 = 18x + 6y – 2

First let's subtract 6y from both sides.

-6y = 18x – 2

Next let's divide both sides by -6.

y = (18 / -6)x - (2 / -6)

y = -3x + 1/3

What will a $160,000 house cost 8 years from now if the price appreciation for homes over that period averages ​7% compounded​ annually?

Answers

Answer:

Step-by-step explanation:

We will use the A=P*(1+r/n)^nt formula

P = 160,000

R = the rate 7%

N= the times compounded. Since it is annually it is 1

T = 8 years

Filling in the information...

A = 160,000 x (1 + .07)^1*8

   = 160,000 x 1.07^8

   = 160,000 x 1.71818617983

   = 274909.788773

Felicia, these questions are tough for a lot of reasons, so it makes sense to me that nobody is giving you the right answers.   here is a right one  :)

Step-by-step explanation:

1st we need a strategy.  brainstorm :P   we are given the cost of material for boxes in area,  we are asked how much 12 boxes would cost.  let's find the area of the material for one box multiply that by the given cost. and then multiply that by 12  for the total cost.  seem good?  Yes there are other good ways to solve this problem if you're thinking that.  this is just how I'm arbitrarily choosing to solve it.

1) surface area of prism box

1a) triangles on ends

1/2* b*p  ( I think 6.2 is P for you, not positive about that)

1/2*6.4*6.2= 19.84  

1b) flat sides

6.4*25 =160 ( this is B )

1c) add up the 5 sides

160*3 + 19.84 * 2  = 839.68 [tex]cm^{2}[/tex]

2) find the cost on 1 box

839.68 [tex]cm^{2}[/tex] *  $0.0001 = 0.8397

about $0.84

3) find the cost for 12 boxes

0.8397 * 12 = 10.076

about $10.08

try those answers :)
