Marty, Doc, and Einstein are all traveling very fast in
their cars. Marty and Doc's position over time are
shown below in the tables. Einstein only collected two
data points during his trip; after 3 hours he travelled
240 miles and after 4 hours he travelled 320 miles.
Who drove the fastest? Show work. Explain on the
lines below.
Answers
Answer:
Doc drove the fastest.
Step-by-step explanation:
The first thing you want to do is figure out how many milese they are traveling per hour. We know that Einstein has these two time stamps (hour/miles) ; 3/240 and 4/320.
so divide the hour by the number of miles:
3÷240=80
just to make sure I did the four hour one as well;
4÷320=80
Do the same thing for doc and marty!
Doc4÷340=85
Marty4÷100=0.04
The answer that you get from the division problems is the number of miles that they travel each hour.
Hope this helps!

A triangle has sides with lengths of 5 centimeters, 12 centimeters, and 15 centimeters. Is it a right triangle
Answers
Answer:
No
Step-by-step explanation:
You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.
This is not true since 144+25 is 169, not 196
Answer:
No, it is not a right triangle.
Step-by-step explanation:
You can determine whether a triangle is a right triangle by using the pythagorean theorem.
a^2 + b^2 = c^2
c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169
c = 13
C would be 13, not 15, so the triangle is not a right triangle

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.
Answers
Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.

Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?
Answers
Answer:
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Step-by-step explanation:
Let the cost of pencil be represented by P, and felt-tip by m. So that;
Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.
⇒ 10P + 7m = 19 .......... 1
Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.
⇒ 3P + 5m = 10.05 .......... 2
From equations 1 and 2,
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Multiply equation 1 by 3, and 2 by 10 to have;
30P + 21m = 57 ......... 3
30P + 50m = 100.5 ....... 4
Subtract equation 3 from 4,
30P - 30P + 50m - 21m = 100.5 - 57
29m =43.5
m = [tex]\frac{43.5}{29}[/tex]
= 1.5
m = 1.5
Substitute the value of m in equation 2,
3P + 5m = 10.05 .......... 2
3P + 5(1.5) = 10.05
3P = 7.5 = 10.05
3P = 3
P = 1.0
Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.
