A taxi driver records the time required to complete various and the distance for each trip. The best-given fit line by the equation y=0.467x + 0.417, where y represents the distance miles, and x represents the time for the trip in minutes. Estimate the distance for a trip that takes 20 minutes, show your reasoning
Answers
Using the line of best fit, it is found that the estimated distance for a trip that takes 20 minutes is of 9.757 miles.
What does the line of best fit gives?It gives the estimated distance in miles of a trip that takes x minutes, according to the following function?
y = 0.467x + 0.417.
In this problem, the trip took x = 20 minutes, hence the distance is given by:
y = 0.467 x 20 + 0.417 = 9.757 miles.

Aaron has three slabs of beeswax. He plans to melt them and use all of the wax to form 36 candles. If all the candles are the same size and weight, how much will each candle weigh?
Answers
Weight of slab of beeswax isn't given.
Assume slab of beeswax = 36 gram.
Answer:
3 gram
Step-by-step explanation:
Each slab of beeswax = 36 gram
Total weight of all 3 slabs = (3 * 36) = 108 g
Number of same-sized candles to make = 36
The weight of each candle will be ;
Total weight of slabs / number of candles
108 g / 36
= 3 grams

I'm supposed to complete the square but my teacher did not explain it well at all. It would be really great if you showed the steps to get the answer :)
Answers
Answer:
x= -74 or -84
Step-by-step explanation:
x^2+3x+37=-7x
x^2+3x+7x+37=0
x^2+10x+37=0
this convert to following
[tex]( - b + - \sqrt{ {b}^{2} } - 4 \times a \times c) \div 2 \times a[/tex]
-b= -(10), a= 1, c =37
according to that
x= -74 or x= -84

Given:
The equation is
[tex]\dfrac{5}{6}h+\dfrac{6}{7}h-\dfrac{9}{14}h=4[/tex]
To find:
The solution of the given equation.
Solution:
We have,
[tex]\dfrac{5}{6}h+\dfrac{6}{7}h-\dfrac{9}{14}h=4[/tex]
It can be written as
[tex]\left(\dfrac{5}{6}+\dfrac{6}{7}-\dfrac{9}{14}\right)h=4[/tex]
[tex]\left(\dfrac{35+36-27}{42}\right)h=4[/tex]
[tex]\left(\dfrac{44}{42}\right)h=4[/tex]
[tex]\dfrac{22}{21}h=4[/tex]
Multiply both sides by 21.
[tex]22h=84[/tex]
Divide both sides by 22.
[tex]h=\dfrac{84}{22}[/tex]
[tex]h=\dfrac{42}{11}[/tex]
Therefore, the solution of the given equation is [tex]h=\dfrac{42}{11}[/tex].
The sum of four consecutive odd integers is –72. Write an equation to model this situation, and find the values of the four integers.
A.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –23; n + 4 = –25; n + 6 = –27
B.
n + (n – 2) + (n – 4) + (n – 6) = –72; n = – 21; n – 2 = –23; n – 4 = –25; n – 6 = – 27
C.
n – (n + 2) – (n + 4) – (n + 6) = –72; n = –20; n + 2 = –18; n + 4 = –16; n + 6 = –14
D.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –19; n + 4 = –17; n + 6 = –15
