Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed of 2 miles per hour. Brian is hiking downhill at a speed of 4 miles per hour. How long will it take for the two to meet?

Answers

Answer:

3.5 hours

Step-by-step explanation:

Distance = 21 miles

Speed * time

Speed * time = distance

Tom speed = 2 mph

Brian = 4 mph

Let time = t

Brian distance + Tom's distance = total distance

4t + 2t = 21

6t = 21

t = 21 / 6

t = 3.5 hours

Craig likes to collect vinyl records. Last year he had 63 records in his collection. No he has 112 records. What is the percent increase in his collection? Round to the nearest whole.

Answers

Answer:

Collection increased by 78%.

Step-by-step explanation:

Last year number of vinyl records in Craig's collection = 63

Now he has number of vinyl records = 112

Number of vinyl records increased = 112 - 63 = 49

Percentage increase in his collection = [tex]\frac{\text{Number of records increase}}{\text{Number of records last year}}\times 100[/tex]

= [tex]\frac{49}{63}\times 100[/tex]

= 77.8

≈ 78%

Therefore, his collection increased by 78%.

Given the equation y = 12x − 25, describe a real-life context that could be modeled by the equation and describe the meaning of the coefficient, variable, and constant term expressed in the equation.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

y = 12x − 25

The initial depth of groundwater being held by a storage tank which extends downward below the ground surface is - 25. The rate of change in depth the groundwater per unit of Rainfall is 12. Hence, a linear model which could model the depth of water in the tank in the described scenario is ;

y = 12x − 25

The rate of change in depth of ground water, y per unit change in number of Rainfall, x gives the slope Coefficient, which equals 12

The intercept value, which is the initial depth of groundwater before, it started raining is - 25

Find two integers whose sum is 20 and product is 99

Answers

Answer:

11 and 9

Step-by-step explanation:

X+Y=20

X*Y=99

Y=20-X

X*(20-X)=99

20X-X^2=99

20X-X^2–99=0

-(X - 11) (X - 9) = 0

Two solutions

X-11=0, X=11

X-9=0, X=9

Y=20-X, so if X is 9, Y is 11

Find the solution of the system of equations.
4x – 8y = -44
2x + 4y = -6

Answers

Answer:

x= -7/2

y= 5/4

Step-by-step explanation:

x-2y=-11

x+2y = -6

then isolate x and set equal to each other

-2y - 6 = 2y -11

4y = 5

y = 5/4

then solve for x using y.

x+5/2 = -6

x = -7/2
