F is a force of 3N pulling an object due north and F is a force of 5N pulling an object 60 east of north.
Determine the direction (measured clockwise from north) and magnitude of the resultant force.

The direction of the force is given as = 38.21⁰ while the magnitude is given as 7N
The magnitude of the resultant force is given as
Fr = [tex]\sqrt{F1^2+F2^2+2F1F2CosO}[/tex]

If you pull a card from a standard deck of 52 and then pull a second card without replacing the first card, you have about a ____ chance(round to nearest percent) of pulling out a face card, followed by on ace.
The probability that you pull a card from a standard deck of 52 and then pull a second card without replacing the first card is 2%
How to determine the probability?The given parameters are:
Cards = 52
Face card = 12
Ace = 4
The probability of selecting a face card is:
P(Face card) = 12/52
Now, there are 51 cards.
The probability of selecting an ace is:
P(Ace) = 4/51
The required probability is:
P = 12/52 * 4/51
Evaluate
P = 0.0181
Express as percentage
P = 1.81%
Approximate
P = 2%

Ingrid Nilsen purchased a $4,000 hydroponic system for her garden. The down payment is 20%, and the
installment loan has an APR of 10% for 36 months. Find the a) down payment, b) amount financed, c) monthly
payment, d) total amount repaid, and e) finance charge.
The purchase of the hydroponic system by Ingrid Nilsen for $4,000 with a 20% down payment at 10% APR for 36 months, and the related calculations, are as follows:
a) down payment = $800.00 ($4,000 x 20%)
b) amount financed = $3,200 ($4,000 - $800)
c) monthly payment = $103.25
d) total amount repaid = $4,517
e) finance charge = $517
How is periodic payment computed?The amount of the periodic payment, finance charge, and total repayment can be computed using an online finance calculator as follows:
Data and Calculations:
Auto Price = $4,000
Loan Term = 36 months
Interest Rate = 10%
Down Payment = $800 ($4,000 x 20%)
Monthly Payment = $103.25
Total Loan Amount $3,200.00
Upfront Payment = $800.00 ($4,000 x 20%)
Total of 36 Loan Payments = $3,717. ($103.25 x 36)
Total Loan Interest = $517
Total Cost (price, interest, tax, fees) = $4,517
Thus, Ingrid Nilsen repaid a total of $4,517 with $517 in interest (finance charge).

what is the surface area of a square based pyramid if the square side is 8 and the pyramid height is 12.
a) 266.39
b) 294.76
c) 525.51
d) 304
Answer:
A) 266.39
Step-by-step explanation:
Answer:
a) 266.39 unit^2.
Step-by-step explanation:
Area of the base = 8^2 = 64 .
There are 4 triangular sides.
To find the area of 1 side we need to know the slant height s of the triangle, This can be found using the Pythagoras Theorem
s^2 = 4^2 + 12^2 = 160
s = √160
So the area of 1 side = 1/2 * base * s
= 1/2 * 8 * √160
and
area of 4 sides
= 4 * 1/2 * 8 * √160
= 202.386
So the Surface area of the pyramid
= 64 + 202.386
= 266.386

Answer:

Step-by-step explanation:
First, we expand everything. The left-hand side is -3(2t) - 1(-3), and we expand it to be -6t+3. The right-hand side is t+t+t+3, and we can reduce it to 3t+3. Now that we have both sides of the equation, we set them to each other.
-6t+3=3t+3 (subtract 3 on both sides)
-6t=3t (add 6t to both sides)

The triangle and the trapezoid have the same area what is the base b of the triangle
Answer:
b =22
Step-by-step explanation:
The formula to calculate the area of a trapezoid:
1/2*(a+b)*h : (a: base, b: base, h: height)
The formula to calculate the area of a triangle:
1/2*a*h (a: base, h: height)
All inputs are given for trapezoid so let's first find the area of trapezoid then we can find the value of b:
1/2*(10+12)*7 = 77 cm^2 is the area of trapezoid
now for the area of triangle:
1/2*b*7 = 77 (it was given that the areas are equal)
first we multiply both sides by 2
7*b = 154 now divide both sides by 7
b = 22
