a rectangle has perimeter 86 cm and length 37 cm. what is its width
Answer:
6 cm
Step-by-step explanation:
37 × 2 = 74 cm86 - 74 = 12 cm12 ÷ 2 = 6 cmSo, the width is 6 cmI hope this helps!
Answer:
The rectangle's width is 6.
Step-by-step explanation:
You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:
86 = 2(37) + 2w
86 = 74 + 2w
Subtract 74 on each side.
2w = 12
Then, divide each side by 2.
w = 6
Hopefully this helped. And good luck in your studies.

If f(1) = 2 and f(n+1) = f(n)^2 – 3 then find the value of f(3).
Answer:
The value of f(3) = -2.
Step-by-step explanation:
First of all, let's find f(2).
[tex]f(n+1)=f(n)^{2}-3[/tex]
[tex]f(1+1)=f(1)^{2}-3[/tex]
[tex]f(2)=f(1)^{2}-3=2^{2}-3=1[/tex]
Now, we can find f(3):
[tex]f(2+1)=f(2)^{2}-3[/tex]
[tex]f(3)=f(2)^{2}-3=1^{2}-3=-2[/tex]
Therefore, the value of f(3) = -2.
I hope it helps you!

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?
Answer:
7 paddleboards
Step-by-step explanation:
In order to solve this, you have to find the total amount that they earned by renting surfboards.
To find this you multiply 55 x 51 =2,805.
Then you use this factor and subtract it from the total amount they earned.
$3,300 - $2,805 = $495.
This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.
495/70 = 7
In conclusion, they rented out 7 paddle boards.

A deposit that is compounded semiannually at 8% for 4 years has a table value of 0.73503 true or false
Answer:
FALSE
Step-by-step explanation:
This answer is false. The interest rate per period is 4% (8% / 2), and the total number of compounding periods is 8 (4 years x 2 periods per year).
Therefore, find the intersection of 4% and 8, which is 0.73069.

Answer:
8.8= slope=1/3
y intercept=4/3
X intercept= -4
8.9 slope=1
Y intercept= 2
X intercept= -2
Step-by-step explanation:
compare the equation with the standard equation Y= MX + C
where M is the slope
to find Y intercept substitute the value of x as 0

write the algebraic expression: The difference of 5 times a number and 11 is 17
Answer:
5x - 11 = 17
Step-by-step explanation:
Answer:
5x - 11 = 17
Step-by-step explanation:
Five times a number is 5x when the number is unknown.
The difference between that number and 11 is (difference means subtract)
5x - 11
All of which = 17
5x - 11 = 17

An urn contains b black balls and r red balls. One of the balls is drawn at random, but when it is put back in the urn c additional balls of the same color are put in with it. Now suppose that we draw another ball.
Required:
Show that the probability that the first ball drawn was black given that the second ball drawn was red is b/(b r c).
Answer:
Please see the explanation below for proof
Step-by-step explanation:
Probability of choosing black ball from the bag
[tex]\frac{b}{b+r}[/tex]
Probability of choosing red ball from the bag
[tex]\frac{r}{b+r}[/tex]
After the addition of c balls of correspondent color –
P (R2/B1) [tex]= \frac{r}{(r+b+c)}[/tex]
P (R2/B2) [tex]=\frac{r+c}{(r+b+c)}[/tex]
B1 and B2 are mutually exclusive event
P (B1/R2) = [tex]\frac{\frac{r}{(r+b+c)} *\frac{b}{b+r}}{\frac{r}{(r+b+c)}*\frac{b}{b+r} + \frac{r+c}{(r+b+c)}* \frac{b}{b+r}}[/tex]
P (B1/R2) [tex]=\frac{b}{(r+b+c)}[/tex]
Hence, Proved
