Answer:
Step-by-step explanation:
Let shall be considering the Cosine rule in this situation.
a^2 = b^2+c^2- 2bc.cosA
Where a = ?
b = 21km
c 45km
A = 131
a^2 = 21^2+45^2-2(21*45).cos131
a^2 = 441+2025-1890(-0.6560)
a^2 = 2466+1239.951
a^2 = 3705.951
a= 60.876km
Finding the bearing of the port from the ship.
We shall be considering the Sine rule
Sin A/a = Sin B/b
Where A = ?
a = 45km
B = 131°
b = 60.876km
Sin A/45 = sin131/60.876
SinA×60.876 = 45×sin131
SinA×60.876= 45×0.7547
SinA×60.876 = 33.961
SinA= 33.961/60.876
SinA = 0.5578
A = sin^-1 0.5578
A = 33.9°

What does the 49 days until Fourth of July there are seven days in a week and how many weeks will it be Fourth of July
Answer:
It will be Fourth of July in 7 weeks.
Step-by-step explanation:
Since you know that there are seven days in a week, you can use a rule of three to find the amount of weeks in 49 days that is the number of days until Fourth of July:
7 days → 1 week
49 days → x
x=(49*1)/7
x=7
According to this, the answer is that it will be Fourth of July in 7 weeks.

0.73 recurring can be writeen as 11/15
Answer:
yes , see explanation
Step-by-step explanation:
We require 2 equations with the recurring 3 placed after the decimal point.
let x = 0.7333.. ( multiply both sides by 10 and 100 )
10x = 7.333... → (1)
100x = 73.333.... → (2)
Subtract (1) from (2) , eliminating the recurring 3
90x = 66 ( divide both sides by 90 )
x = [tex]\frac{66}{90}[/tex] = [tex]\frac{11}{15}[/tex]

Quadrilateral ABCD is inscribed in circle O.
What is m∠A ?
Answer:
42 degrees (check attachements) hope it helps!
Step-by-step explanation:
Answer:
42
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. We use that information and angles B and D to find the value of x. Then we use the value of x to find the measure of angle A.
m<B + m<D = 180
2x + 3x - 5 = 180
5x = 185
x = 37
m<A = x + 5
m<A = 37 + 5
m<A = 42

Marcus receives an inheritance of $3,000. He decides to invest this money in a 11 -year certificate of deposit (CD) that pays 5.0 % interest compounded monthly. How much money will Marcus receive when he redeems the CD at the end of the 11 years?
Marcus will receive $5,193.82 when he redeems the CD at the end of the 11 years.
What is compound interest?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
A=P(1+r/n[tex])^{nt}[/tex]
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Marcus receives an inheritance of $3,000.
He decides to invest this money in an 11 -year certificate of deposit (CD) that pays 5.0 % interest compounded monthly.
P = $3,000
r =5%
t = 11 years
A=P(1+r/n[tex])^{nt}[/tex]
Substitute the values of P, r and t in the formula,
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A=P(1+r/n[tex])^{nt}[/tex]
A = 3,000.00(1 + 0.05/12[tex])^{(12)(11)}[/tex]
A = 3,000.00(1 + 0.0041666666666667[tex])^{132}[/tex]
A = $5,193.82
Therefore, Marcus will receive $5,193.82.

Cindy owns a rectangular lot that is 18 yards long and 45 feet wide.
She is going to cover the lot with square pieces of sod. If the sod costs $12 per square yard, how much will Cindy pay to completely cover the lot with sod?
Answer:
$3240
Step-by-step explanation:
First you need to find the area of that lot. Area of a rectangle = length x width. But you also have mixed units...yards and feet. Since the price of the sod is in square yards, we'll convert the 45 feet to yards. 3 feet = 1 yard, so divide 45 by 3, = 15 yards.
18 x 15 = 270 square yards
then you multiply that by the $12/square yard
270 x 12 = $3,240

month?
PLEASE ANSWER ASAP!
Answer: y= 100x +1500
Step-by-step explanation:
The 1500 value never changes, so it doesn’t need a variable
The 100 value will change based on how many he sells, so it needs a variable
Answer:
its the first one.
Step-by-step explanation:
the 1500 stays the same so it would be 100×how ever many tractors so 100z+1500

Here is a system of linear equations: -2x + y = 7
6x + y = 11
What is the solution to the system of equations shown?
A
(1/4, 7 1/2)
B.
(2, 11)
c.
(1/2, 8)
D.
(3, -7)
Yes
Answer:
c. (1/2, 8)
Step-by-step explanation:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
-2x + y = 7
Step 1: Subtract y from both sides of the equation.
-2x = -y + 7
Step 2: Divide both sides by -2
x = 1/2y - 7/2
Substitute what you see above this statement for y in the other equation.
6(1/2y - 7/2) + y = 11
Step 3: Multiply 6 by 1/2y - 7/2.
3y - 21 + y = 11
Step 4: Combine y and 3y.
4y - 21 = 11
Step 5: Add 21 to both sides
4y = 11 + 21
4y = 32
Step 6: Divide both sides by 4.
y = 32/4
y = 8
Step 7: Substitute 8 for y in x = 1/2y - 7/2 Because the resulting equation contains only one variable, you can solve for x directly.
x = 1/2(8) - 7/2
Step 8: Multiply 1/2 by 8.
x = 4 - 7/2
Step 9: Add -7/2 to 4.
x = 1/2
The system is now solved, and we get C (1/2, 8) as our answer.

Answer:
Middle answer is right
Step-by-step explanation:
The first answer is obliviously wrong so therefore it is the last two options
-(x+1)^2
= -(x^2+2x+1)
= -x^2-2x-1-3 (add the -3)
= x^2-2x-4
y intercept make x=0 therefore y=-4
AOS is x= -b/2a
x=2/2 which is 1
therefore it isthe middle answer

Here is it 13 more to go
Step-by-step explanation:
Formula for simple interest:
[tex]a = p(1 + rt)[/tex]
where
a = final amount
p = principal amount
r = interest rate per annum
t = time in years
Now, we are finding a, the final amount, and given,
p = $650
r = 5.5% (5.5/100)
t = 4 years
[tex]a = 650(1 + (\frac{5.5}{100} )(4)) \\ = 650(1 + (0.055)(4)) \\ = 650(1 + 0.22) \\ = 650(1.22) \\ = 793 \: dollars[/tex]
Answer:
C.$793
Step-by-step explanation:
were looking to 5.5% of 650 but in order to do that first we need to find 1%, we can do that by dividing by 100
650=100%
/100 /100
6.5=1%
now we can multiply by 5.5 to get 5.5%
6.5 = 1%
x5.5 x5.5
35.75=5.5%
now we are looking to find how much money is in the account total after 4 years
so the equation is
(35.75x4)+650
143+650
$793 in total
