A map of New York has a scale of 1/2 inch : 5 miles. Cindy knows the
distance to her grandmother's house is 85 miles. How many inches will the
distance be on the map?
Answer:
8.5 inches
Step-by-step explanation:
1/2 in = 5 miles
? = 85 miles.
So you would do 85/5 to figure out how many times you have to multiply 5 to get to 85.
85/5= 17
So then you would multiply 17 by 1/2 to get the answer 8.5. So that would b 8.5 inches

You found Genie hidden in a dungeon. Genie is offering two different options for you as a reward for finding him. There are two options shown for you to choose.
Which option would you choose? Explain your reasoning using the key features of exponential functions.
Answer:
The first option is
A(x) = 10000(1.05)ˣThe second option is:
B(0) = 1000B(1) = 1100The ratio is 1.1 and the zero term is 1000The equation for this option is:
B(x) = 1000(1.1)ˣNow, which option is better?
It depends on the number of x. It is assumed the genie is offering money or similar reward.
For the values of x below 50 option A is better and option B is much better for x > 50.
See the graph in the attachment, where green line represents the option A and red line is option B.

A rocket is launched from a hill, the hill is 80 ft high and the rocket has a velocity of 64 ft/s what is the maximum height of the rocket and when will it reach that height?
Answer:143.60 ft
Step-by-step explanation:
Given
Height of hill [tex]h=80\ ft[/tex]
the launch velocity of the rocket is [tex]u=64\ ft/s[/tex]
At maximum height, the velocity of the rocket is zero
using the third equation of motion [tex]v^2-u^2=2as[/tex]
[tex]\Rightarrow 0^2-64^2=2\times (-32.2)\times s\\\Rightarrow s=\dfrac{64^2}{64.4}=63.60\ ft[/tex]
The maximum height will be [tex]80+63.60=143.60\ ft[/tex]

To solve the system of equations below, Elena begins by multiplying the first equation by 5.
2x + 3y = 14
7x + 5y = 16
PART A
Elena wants to eliminate a variable by adding the equations together. By what integer could
Elena multiply the second equation?
PART B
Solve the system of equations algebraically. You may use Elena's strategy or one of your own.
Show your work.
Answer:
x = -2
y = 6
Step-by-step explanation:
Part A
If she multiplies the 1st equation by 5, then she should multiply the 2nd equation by -3. Then add the two results
(1) 2x + 3y = 14 (2) 7x + 5y = 16
10x + 15y = 70 -21x - 15y = -48
-21x - 15y = - 48
-11x = 22
x = - 2 7(-2) + 5y = 16
-14 + 5y = 16
5y = 30
y = 6

20
Step-by-step explanation:
Turn 40% into a decimal (.40) and then mulitply by 50.
.40 x 50 = 20
Eli is now one quarter of his father's age. In 5 years time his age will be one third of his father's age. How old is Eli now
Answer:
20 years old
Step-by-step explanation:
The age of Eli would be 20 years old
What is a numerical expression?A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Consider E and F represent Eli and his Father's current ages.
We are told that E = (1/4)F.
Eli is now one quarter of his father’s age.
But in 5 years, that will be:
(E+5) = (1/3)(F+5)
In 5 years’ time his age will be one third of his father’s age.
We have two equations and two unknowns.
To Find a way to eliminate one of the two variables and then solve for the remaining variable.
E = (1/4)F
(E+5) = (1/3)(F+5)
This seems to me the easiest would be to use the first equation's definition of E [=(1/4)F] in the second equation:
(E+5) = (1/3)(F+5)
((1/4)F+5) = (1/3)(F+5)
(1/4)F - (1/3)F = (1/3)*5 - 5
F - (4/3)F = (4/3)*5 - 20
-(1/3)F = (20/3) - (60/3)
-(1/3)F = (-40/3)
F = (120/3)
F = 40 years
E = 10 years (based on E = (1/4)F)
In five years, F is 45 and E is 15, that would make Eli 1/3 of his father's age in 5 years.

Solve for t.
4 = 2 + 2/5 t
Answer:
T = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4=2/5t + 2
Step 2: Flip the equation.
2/5t + 2 = 4
Step 3: Subtract 2 from both sides.
2/5t + 2 − 2 = 4 −2
2/5t = 2
Step 4: Multiply both sides by 5/2.
(5/2) *(2/5t)= (5/2) *(2)
Answer:
t=5
Answer:
t=5
Step-by-step explanation:
4=2+2/5 t
Subtract 2 from both sides
2=2/5 t
Multiply 2/5 by its reciprocal on both sides so multiply by 5/2
(5/2) times 2 is 5
so t is 5
