Hikers on a backpacking trip take 2 hours and 10 minutes to hike the first 2.6 miles of an 8-mile hike. At this pace, which amount of time best approximates how long they will take to hike the entire 8 miles of the trip.
A. 6 hours and 30 mins
B. 6 hours and 40 mins
C. 7 hours and 35 mins
D. 9 hours and 36 mins
Answers
Answer:
B. 6 hours and 40 mins
Step-by-step explanation:
Create a proportion where x is the amount of time to hike the entire 8 miles.
Represent the time in minutes:
[tex]\frac{130}{2.6}[/tex] = [tex]\frac{x}{8}[/tex]
Cross multiply and solve for x:
2.6x = 1040
x = 400
Convert this to hours:
400/60
= 6.67 (6 hours and 40 mins)
So, the correct answer is B. 6 hours and 40 mins

The solution of the equation is 17.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given an equation as;
(5x+17)+129+94+(7x-46)+(9x-11)=540
Solving;
5x+7x+9x+17+129+94-46-11=540

sixty-eight percent of valley creek school students attend this year's homecoming dance if 459 students attend the dance how many students are in the school?
Answers
The total number of students in the school will be 675.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that sixty-eight per cent of valley creek school students attend this year's homecoming dance if 459 students attend the dance.
The number of students will be calculated as,
68% ⇒ 459
1% ⇒ 459 / 68
100% ⇒ (459 x 100 ) / 68
100% ⇒ 675 students
Therefore, the total number of students in the school will be 675.

A group of friends are at a baseball game and are purchasing souvenirs. Olivia purchased 1 t-shirt and 5 baseball caps, spending a total of $165. Her Marco purchased 1 t-shirt and 4 baseball caps, which cost him a total of $137. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
Answers
Answer:
baseball cap = $28
t-shirt = $25
Step-by-step explanation:
Olivia: t +5b = 165
Marco: t + 4b = 137
isolate t in Olivia's equation
t = 165 - 5b
plug t into Marco's equation
165 - 5b + 4b = 137
165 - b = 137
b = 28
plug b into either equation
t + 4b = 137
t + 4(28) = 137
t + 112 = 137
t = 25

Answers
Answer:
y=6x+3
Step-by-step explanation:
1.6x-y=1 solve for y
-y=-6x+1 divide bot sides by -1
y=6x-1
slope is 6
the slopes of parallel lines are equal
y-(-3)=6(x-(-1))
y+3=6(x+1)
y+3=6x+6
y=6x+6-3

What is the slope of a line perpendicular to the line of the equation in the above ? Please help answer !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
- 4Step-by-step explanation:
Slopes of perpendicular lines are negative-reciprocals.If m is the slope of one line, the slope of the perpendicular line is -1/m.Let's find the slope of the given line:
x - 4y = -12Rewrite this in the slope-intercept form: y = mx + b
x - 4y = -124y = x + 12y = 1/4x + 3The slope is 1/4
The perpendicular line has slope
- 1/(1/4) = - 4
