Answer:
each pencil almost costs 83 cents which is the value of p
Step-by-step explanation:
Here most important data that the amount which Kate had before the purchase of pencils is missing.
For our convenience i am assuming Kate had $10 before the purchase of pencil.
Since, after purchase the left with Kate = $4.20
Therefore, amount spend on purchase of pencils = $10-$4.20 = $5.80
In $5.80 Kate purchased 7 pencils
Therefore cost of each pencil p = 5.80/7 = $0.8285 ≅ $0.83
Therefore each pencil almost costs 83 cents which is the value of p
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?
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
9. Bella hiked a 13-kilometer trail at Great Peak. How many meters did Belle
hike? 1km = 1,000m
A 0.13
B 0.013
C 1,300
D 13,000
9.)
Answer:
D. 13,000
Step-by-step explanation:
If there are 1,000 m in 1 km, we can find the number of meters she hiked by multiplying 13 by 1,000:
13(1000)
= 13,000
So, Belle hiked 13,000 meters.
The correct answer is D. 13,000

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.
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

Step-by-step explanation:
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.
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%.
Write the equation of the line in Slope-Intercept form that passes through the point (4,-7) and has the same slope as y=1/4 x +3
Answer:
Step-by-step explanation:
y + 7 = 1/4(x - 4)
y + 7 = 1/4x - 1
y = 1/4x - 8

Find the solution of the system of equations.
4x – 8y = -44
2x + 4y = -6
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
10 is 6% of what number
Answer:
166.67
Step-by-step explanation:
We have, 6% × x = 10 or, 6/100 × x = 10
Multiplying both sides by 100 and dividing both sides by 6,
we have x = 10 × 100/6
x = 166.67
If you are using a calculator, simply enter 10 × 100 ÷ 6, which will give you the answer.
Hope this helps

Find two integers whose sum is 20 and product is 99
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
Y=20-X, so if X is 11, Y is 9
The two numbers are 11 and 9

At an amusement park, anyone who is taller than 5 feet is allowed to ride the rollercoasters. Write an algebraic inequality using y to represent those who are taller than 5 feet and can ride the rollercoaster.
Answer:
y > 5
Step-by-step explanation:
To ride the Rollercoaster, height must be above 5 feets
y = height
Hence, the inequality representing those who can ride the Rollercoaster is :
Height above 5 feets
y > 5
Hence, anybody for which the inequality statement is true can ride the Rollercoaster.
