How many pennies are on the nth square? 2n 2n – 1 2n 1 2n – 1 2n 1
The number of pennies is on the [tex]\rm n^t^h[/tex]square is [tex]\rm 2^n^-^1[/tex].
I am assuming the:
1 penny = [tex]2^0[/tex]
2 pennies = [tex]2^1[/tex]
3 pennies = [tex]2^2[/tex]
and so on.
It is required to find how many pennies are on the [tex]\rm n^t^h[/tex] square.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have:
1 penny = [tex]2^0[/tex]
2 pennies = [tex]2^1[/tex]
3 pennies = [tex]2^2[/tex]
If we observe the pattern, we see it on the [tex]\rm n^t^h[/tex] square the number of pennies will be [tex]\rm 2^n^-^1[/tex]
[tex]\rm n^t^h= 2^n^-^1[/tex]
Thus, the number of pennies is on the [tex]\rm n^t^h[/tex]square is [tex]\rm 2^n^-^1[/tex].

Solve for the value of r.
(6r-7)
55°
Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)

A rectangular pool is 6 feet long and 5 feet wide. It is filled to a depth of 2 Teet. A cubic footof water is about 7.5 gallons. If the pool can be filled at a rate of about 10 gallons per minute,now long will it take to fill the pool to a depth of 2 feet? Explain your reasoning.
*QUICK*
Answer:
450 minutes
Step-by-step explanation:
First, let's calculate the volume of the pool when filled. Volume will be: (length x width x height).
Volume = 6' x 5' x 2 ' = 60 ft^3
1 ft^3 of water occupies 7.5 gallons. That's a conversion factor for water: (7.5 gal)/(1 ft^3).
The total gallons of water in a filled pool would be:\
(60 ft^3)*((7.5 gal)/(1 ft^3)) = 4500 gallons
At a rate of 10 gallons/min, it would take:
(4500 gallons)/(10 gallons/min) = 450 minutes, or 450/60 = 7.5 hours

Mr. Hayden's Bible class collected $11
in coins for a needy family. They col-
lected twice as many quarters as dimes
and 12 more nickels than dimes. How
many of each coin did the class collect?
This is the only way I can think of this mathematically. This took a good 20 minutes for me. You need to guess and check. Like try 17 quarters, 50 nickels, and 37 dimes etc. until you get 11.00. My numbers are mathematically correct but we both know you cant have 18.909 quarters so. lol
Answer:
Quarters: 18.909
Nickels: 49.818
Dimes: 37.818
Somewhere around those numbers.
Step-by-step explanation:
$11.00 total in coins
Nickel = $0.05
Dime = $0.10
Quarter = $0.25
(n*0.05) + (d*0.10) + (q*0.25)
Solve the equation for q.
[tex]q=\frac{1}{2} d[/tex]
(n*0.05) + (d*0.10) +( [tex]\frac{1}{2} d[/tex] *0.25)
Simplify the expression.
9d + 2n = 440
d - n = -12
Multiply both sides of the equation by -9.
-9d + 9n = 108
9d + 2n = 440
Sum the equations vertically to eliminate at least one variable.
11n = 548
[tex]n=\frac{548}{11}[/tex]
Substitute the given value of n into the equation d - n = -12
[tex]d-\frac{548}{11} =-12[/tex]
[tex]d=\frac{416}{11}[/tex]
Substitute the given value of n into the equation [tex]q=\frac{1}{2} d[/tex]
[tex]q=\frac{1}{2} *\frac{416}{11}[/tex]
[tex]q=\frac{208}{11}[/tex]
Finally
[tex]d=\frac{416}{11}[/tex] d = 37.818
[tex]n=\frac{548}{11}[/tex] n = 49.818
[tex]q=\frac{208}{11}[/tex] q = 18.909

Executives for a car dealership are interested in the sales for the type of vehicle, SUV or truck, and the type of power train, two-wheel drive (2WD), four-wheel drive (4WD), or all-wheel drive (AWD). The data from the
sales of 165 vehicles are displayed in the two-way table.
A vehicle is randomly selected. Let S be the event that
the vehicle is an SUV and let D be the event that the vehicle has 4WD. What is the value of P(S and Dc)?
O 0.04
O 0.23
O 0.38
O 0.41
Assuming S is the event that the vehicle is an SUV the value of P(S and D) is:0.38.
ProbabilityNumber of vehicles=165
Total number of SUV=10+23+52=85
Hence:
The event that vehicle is SUV(S)=85
The event that vehicle is 4WD(D)=23
Value of P(S and D)=85-23/165
Value of P(S and D)=62/165
Value of P(S and D)=0.375
Value of P(S and D)=0.38 (Approximately)

A triangle has two sides of length 2 and 14. What is the largest possible whole-number length for the third side?
Answer:
15
Step-by-step explanation:
Note that;
The sum of the lengths of 2 sides of a triangle must be greater than but not equal to the length of the third side.
As well as, the third side must be longer than the difference between the greater and the lesser of the other two sides
Given;
First side of the triangle = 17
Second side of the triangle = 2
Let us assume the third side of the triangle = T
Now, In any given triangle:
"Sum of any two sides of a triangle is strictly greater than the third side."
⇒ Sum of first side + Sum of second side > Third Side
or, m < 2 + 14
or, m < 16
Hence, the largest possible value for m = 15

Beverly has a bag of marbles that weighs 30 grams. She knows that each marble weighs 1.5 grams and the bag weighs 1.5 grams.
Which equation could she use to determine how many marbles are in the bag? Select all that apply.
(1.5)x + 1.5 = 30
30 – x = 2(1.5)
(1.5)(30) = 1.5x
1.5 + x = 30
1.5x = 30 – 1.5
This is slope
Weight of bag(fixed)=1.5The equation is
[tex]\\ \tt\Rrightarrow 1.5x+1.5=30[/tex]
Let's find out

Find the equation of the line through point (10,4) and parallel to 3x+5y=8. Use a slash ("/") for fractions (e.g. 1/2 for 12). DO not include spaces in your answers.
Answer:
3x + 5y = 50
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + 5y = 8 ( subtract 3x from both sides )
5y = - 3x + 8 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + [tex]\frac{8}{5}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{5}[/tex]
Parallel lines have equal slopes , then
y = - [tex]\frac{3}{5}[/tex] x + c ← is the partial equation
to fid c substitute (10, 4 ) into the partial equation
4 = - 6 + c ⇒ c = 4 + 6 = 10
y = - [tex]\frac{3}{5}[/tex] x + 10 ← equation of parallel line in slope- intercept form
multiply through by 5 to clear the fraction
5y = - 3x + 50 ( add 3x to both sides )
3x + 5y = 50 ← equation of parallel line in standard form
Solution:
Step-1: Convert the equation of the line into slope intercept form.
3x + 5y = 8=> 5y = -3x + 8=> y = -3x/5 + 8/5In this case, the slope we obtained is -3/5, which is -0.6. Let's use point slope form to find the original equation.
Step-2: Use point slope form.
y - y₁ = m(x - x₁)=> y - 4 = -0.6(x - 10)=> y - 4 = -0.6x + 6=> y = -0.6x + 10Type the correct answer in each box. Use numerals instead of words.

the parallel line is y = 8x + 6
Step-by-step explanation:
so to solve for a parallel line we already know that the slopes are the same. so rn we can write:
y = 8x + b
but since we do not know the y-intercept we can use the points given to find it
we substitute them
-2 = 8(-1) + b
-2 = -8 + b
b = 6
the parallel line is y = 8x + 6
