Answer:

$4.257

Step-by-step explanation:

Given:

Items delivered per hour = 14

Fixed hourly costs​ = ​$47

variable cost = $0.90

Now,

at breakeven point, the profit = 0

or

Total revenue = total cost

let the charge at breakeven point be 'x'

thus,

x × 14 = $47 +  ($0.90 × 14)

or

x × 14 = $47 + $12.6

14x = $59.6

or

x = $4.257

Hence, the breakeven charges are $4.257

Find the measures of:<br><br>all angles if 3(m∠1+m∠3) = m∠2+m∠4
slavikrds [6]

Answer:

Part 1) m∠1=45°

Part 2) m∠3=45°

Part 3) m∠2=135°

Part 4) m∠4=135°

Step-by-step explanation:

we know that

m∠1=m∠3 -----> by vertical angles Equation A

m∠2=m∠4 -----> by vertical angles Equation B

m∠1+m∠2=180° ----> by supplementary angles (linear pair) Equation C

3(m∠1+m∠3) = m∠2+m∠4 ----> Equation D

Substitute equation A and equation B in equation D

3(m∠1+m∠1) = m∠2+m∠2

6(m∠1) = 2m∠2

3(m∠1) =m∠2 -----> equation E

Substitute equation E in equation C and solve for m∠1

m∠1+3(m∠1)=180°

4(m∠1)=180°

m∠1=45°

<em>Find the measure of m∠3</em>

Remember that

m∠1=m∠3 (equation A)

therefore

m∠3=45°

<em>Find the measure of m∠2</em>

Remember that

m∠2=3(m∠1) (equation E)

substitute the value of m∠1

m∠2=3(45°)=135°

<em>Find the measure of m∠4</em>

Remember that

m∠2=m∠4 (equation B)

therefore

m∠4=135°

Match the values associated with this data set to their correct descriptions
nordsb [41]
Put the numbers in order
6,7,15,36,41,43,47,49

Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile

difference of largest value and median.....(49 - 38.5) = 10.5

What is the distance between (0, 0) and (-7, -3)? Round your answer to the nearest tenth.
lyudmila [28]

Answer:

Distance = -7.6

Step-by-step explanation:

Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)

√((-7 - 0))^2 + (-3 - 0)^2) = 7.6
