Answer:
The bearing of B from C is 22° counterclockwise
Step-by-step explanation:
∠CAB = 210 - 90 = 120°
Extend a line from A to the west.
drop a perpendicular line from that line to point C.
Let's call the point at the perpendicular point, M.
∠MAC = 180° - 120° = 60° because they are supplementary.
Now we have a right ∠CMA with a known hypotenuse and a known angle.
Solve for MA:
cos 60° = MA/3.8 = 1.9
Solve for MC:
sin 60° = MC/3.8 = 3.29
MB = 1.9 + 6.4 = 8.3
tan ABC = 3.29/8.3 = 21.62°

A $3,000 deposit for 66 months compounded at an annual interest rate of 1.6%. What is the interest and the account balance at the end of the 66 months
Answers
Answer:
interest: $275.77balance: $3,275.77Step-by-step explanation:
The account value is given by the compound interest formula:
A = P(1 +r/12)^n
Principal P invested at annual rate r compounded monthly for n months.
__
Using your parameters, the account balance would be ...
A = $3000(1 +0.016/12)^66 = $3275.77 . . . account balance
The interest is the difference between this balance and the original investment amount:
interest = $3000 -3275.77 = $275.77 . . . interest
Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each.
Answers
Step-by-step explanation:
here's your solution
=> total money received by them = $1600
=> the given ratio are 7:5:4
=> let the ratio be X ,now
=> Maria = 7X
=> Carolina = 5X
=> Pedro = 4X
=> we know whole money = $1600
=> so, adding all
=>. 7x + 5x + 4x = $1600
=> 16x = $1600
=> x= $1600/16
=>. x = $100
now Maria = 7*100 = $700
Carolina = 5*100 = $500
Pedro = 4*100 = $400

What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Fixed amount he earns per week = $15
Additional amount added depending on the number of subscription sold = $3
Let x be the number of subscription sold.
Amount earned in a week = 15 + 3x
If amount earned is $90,
15 + 3x = 90
3x = 75
x = 75 / 3 = 25
Hence the number of subscriptions is 25.

x+4y=−5
Divide each term by 7 and simplify.
y=17−5x/7
x+4y=−5
Subtract x from both sides of the equation.
y=1/7−5x/7
4y=−5−x
y=1/7−5x/7
Divide each term by 4 and simplify.
y=1/7−5x/7
y=−5/4−x/4
