Now I used Desmos to solve this, im sure theres a way to find it the legit way but i'm too lazy. Here's the image of what the graph is like:
brush =$20.21,. sketchbook =$6.21 , paint set=$9.32
Step-by-step explanation:
let the cost of the brush=x
the cost of the sketchbook=y
the cost of the paint set= z
total money used= $39.75-$4.00
=$35.75
x= 14+y
but y=2/3z
x= 14+2/3z
14+2/3z +2/3z +z =35.75
3×14 +3×2/3z+3×2/3z×3z=3×35.75
42 +2z +2z +3z =107.25
7z=107.25-42
7z=65.25
z=65.25/7
z=$9.32
y=$2/3×9.32
y=$6.21
x=14+y
x=14+6.21
x=$20.21
b + 1.5 = 6
solve the equation and find the value of the variable
Answer:
[tex]\boxed{\sf{b=4.5}}[/tex]Step-by-step explanation:
To find the value of variable, you have to isolate the term of b from one side of the equation.
b+1.5=6First, you subtract by 1.5 from both sides.
→ b+1.5-1.5=6-1.5
Solve.
Subtract the numbers from left to right.
⇒ 6-1.5=4.5
⇒ b=4.5
Therefore, the correct answer is b=4.5.I hope this helps you! Let me know if my answer is wrong or not.
Find the average rate of change from x = 1 to x=5
Answer:
The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
Therefore the slope, or the average rate of change, between these points is 2.

A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
16)
One angle = 90 degrees
So,
The other two angles' sum must be 90 degrees.
So,
Angle classification: right angle
Side classification : isosceles
17)
We see that all sides are equal.
So,
All angles must be equal and the sum is 180.
So,
Angle classification: acute angle
Side classification: equilateral
18)
One angle is greater than 90.
So,
Angle classification: obtuse angle
Side classification: scalene
Thus,

Mr. Alexander was traveling home from a business
trip. A taxi driver took him from his hotel room to a
bus station that was 18 miles away. The taxi traveled at an average rate of 60 miles an hour.
Mr. Alexander waited 15 minutes at the bus station
before leaving on a 178-mile bus ride.
Mr. Alexander's trip took a total of 5 hours from the time he left the hotel to the time the bus arrived at its destination. At
what average rate did the bus travel? Explain or show calculations to support the answer.
Using the relation between velocity, distance and time, it is found that the bus traveled at a rate of 40 miles per hour.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
The taxi took 18 minutes(60 miles per hour = 1 mile per minute), while he waited for 15 minutes at the station. Thus, the 178-mile bus trip took 4 hours and 27 minutes, so t is given by:
[tex]t = 4 + \frac{27}{60} = 4.45[/tex]
Hence, the velocity is given by:
[tex]v = \frac{d}{t} = \frac{178}{4.45} = 40[/tex]
The bus traveled at a rate of 40 miles per hour.

Jack has $15,000 to invest. If he invests two-thirds of it into a high-yield savings account with an annual interest rate of 8%, compound continuously, and the other third in a regular savings account at 6% simple interest, how much does Jack earn after one year?
Based on the amounts that Jack invested into the different investment vehicles, the amount Jack earns a year would be $1,132.87.
How much does Jack earn from the high-yield savings account?The amount invested is:
= 2 / 3 x 15,000
= $10,000
Amount after a year:
= Amount x e ^ (rate x time)
= 10,000 x e ⁰.⁰⁸ ˣ ¹
= $10,832.87
How much does Jack make from the regular savings account?Amount invested:
= 1/3 x 15,000
= $5,000
Amount after a year:
= 5,000 x (1 + 6%)
= $5,300
How much did Jack earn in a year:= (10,832.87 + 5,300) - 15,000
= $1,132.87

The circumference of the Earth is 2.4x10^4 miles. If you traveled at an average of 8.5x10 miles per hour, how long would it take for you to go around the Earth? Round your answer to the nearest whole number.
It will take approximately 282.352 hours for one to go round the earth, this is equivalent to 11.764 days
Speed, Distance and TimeGiven Data
Circumference of Earth = 2.4x10^4 milesDistance round the earth = 2.4x10^4 milesSpeed = 8.5x10 miles per hourWe know that the relationship between speed, distance and time is given as
Speed = Distance/Time
Hence,
Time = Distance/Speed

a maxicool consists of a cone full of ice cream with a hemisphere of ice cream on top. the radius of a hemisphere is 3cm. The height of the cone is 10cm. calculate the total volume of the ice cream round your answer to the nearest tenth
According to the information, it can be inferred that the volume of the ice cream is close to 207.33 cm³
How to calculate the volume of the maxicool?To calculate the volume of the maxicool, we must calculate the volume of the sphere of ice cream, and the volume of the cone that is filled with ice cream.
Volumen of the sphereV = [tex]\frac{4}{3}[/tex] × π × R³
V = [tex]\frac{4}{3}[/tex] × π × 3³
V = 113.09 cm³
Cone volume
V = [tex]\frac{1}{3}[/tex] × π × R² × h
V = [tex]\frac{1}{3}[/tex] × π × 3² × 10
V= 94.24 cm³
Finally we must add both values to know the total volume of the maxicool.
113.09 + 94.24 = 207.33 cm³
