A high school track is shaped as a rectangle with a half circle on either side. A rectangle has a length of 85 yards and width of 25 yards. 2 semicircles with diameters of 25 yards are on each end of the rectangle. Jasmine plans on running three laps. How many yards will Jasmine run? Use 3. 14 for Pi. 248. 5 yd 490. 5 yd 725. 5 yd 745. 5 yd.
perimeter=2(85)+π(12.5)=220+2×12.5π
=170+25×3.14

=248.5
distance ran=3×248.5=745.5 yards.

Justin has 64 ounces of lemonade to divide among 9 people. When he types 64÷9 into his calculator, the number that appears is 7.111111111. How much lemonade should he give to each person?
The number of lemonade should Justin give to each person is 7 with one lemonade still left.
It is given that Justin has 64 ounces of lemonade to divide among 9 people.
We have to find out that how much lemonade should he give to each person.
What will be the value of each part , if 120 is divided in 6 equal parts ?
The value of each part will be 120 divided by 6 or 120 ÷ 6 or 20 i.e., 120 is divided into 6 equal parts of 20 each.
As per the question ,
No. of ounces of lemonade to divide among 9 people = 64
No. of lemonade each people will get = 64 ÷ 9
or
64 ÷ 9 = 7.1111
So , we can't equally divide it because if 7 each is divided between 9 people , one lemonade will still be left.
i.e.,
7 × 9 = 63
64 - 63 = 1
1 still left
Thus , the number of lemonade should Justin give to each person is 7 with one lemonade still left.

Scott had a balance of $1910.30 in his bank account on August 1st. On August 12th, he wrote a check to the local car shop for $75.00, then on August 21st his friend gave him a check for deposit $41.50. Then he bought groceries for 210.25. How much money does she have in her bank account?
Answer: $1,666.55
Step-by-step explanation:
The amount of money that Scott will have in the bank will be the total of the money that was in the bank at the beginning of August plus any money received, less any money that was disbursed.
= Beginning balance + check from friend - check to local car shop - cash spent on groceries
= 1,910.30 + 41.50 - 75.00 - 210.25
= $1,666.55
Figure is assuming groceries were paid for by cash from bank account.
Cesar is excited that he only has 12 months left before he pays off his credit card completely. His current balance is $3,750 and his APR is 17. 5%. But when he is involved in a car accident, he is forced to use his credit card to pay a $1,000 deductible to get his car fixed. How much will Cesar’s minimum monthly payment increase if he still wants to pay off his credit card in 12 months? a. $83. 33 b. $91. 44 c. $342. 91 d. $434. 35.
The amount by Cesar’s minimum monthly payment increase will be $91.44.
What will be the amount?Cesar only has 12 months left before he pays off his credit card completely.
His current balance = $3,750
APR = 17.5%
Now we use the formula :
[tex]\rm Present \ value \ of \ anuity= P=( 1-\frac{1+r}{r} })^{-n}[/tex]
PV = Present Value
P = Periodic payment
r = rate per period
n = number of period
Now for the first case:
PV of annuity = $3,750
P =?
r = 17.5% annually = % monthly monthly
n = 12 months
Now we put the values in the formula
[tex]3750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]
[tex]P=\dfrac{3750}{\dfrac{1-0.8405}{0.01458} }[/tex]
[tex]P=342.91[/tex]
Now for the second Case :
PV of annuity = 3750 + 1000 = 4750
P =?
r = 17.5% annually = % monthly = monthly
n = 12 months
Putting the values in the formula
[tex]4750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]
[tex]P=\dfrac{4750}{1-\dfrac{1+\frac{17.5}{1200} }{\frac{17.5}{1200} } }[/tex]
[tex]P=\dfrac{4750}{\dfrac{0.1595}{0.01458} } =434.35[/tex]
Cesar's increased monthly payment will be
434.35 - 342.91 = 91.44
Hence, the amount by Cesar’s minimum monthly payment increase will be $91.44.

Given the figure below, find the values of x and z.
Answer:
make me brainlaiest.....
Answer:
The value of x = 5
The value of z = 107
Step-by-step explanation:
=> (6x+43)° +107° = 180° { linear pair }
=> 6x+43 +107 = 180
=> 6x + 150 = 180
=> 6x = 180-150
=> x = 30/6
=> x = 5
Now solve for z ,
107 = z { Vertically opposite angle }
yoko made $323 for 17 hours of work. at the same rat how much would she make for 8 hours of work
Answer:
$152
Step-by-step explanation:
To find Yoko's hourly pay, we will divide the $323 she made after working by 17, which is the number of hours she worked:
323 ÷ 17 = 19
We now know that Yoko makes $19 an hour (dang, she's probably a doctor or something) however, we're not done yet.
We will multiply $19 by 8 hours of work to see how much she'll make after 8 hours:
19 × 8 = 152
Yoko makes $152 after 8 hours of work.

find f(-1)+g(2)
f(x)=5x-20
g(x)=x^2+5x-11
Step-by-step explanation:
f(x) = 5x - 20
f(-1) = 5(-1) - 20 = - 5 - 20
= - 25
g(x) = x² + 5x - 11
g(2) = 2² + 5(2) - 11 = 4 + 10 - 11
= 3
Thus, f(-1) + g(2) = - 25 + 3 = - 22
Answer:
Step-by-step explanation:
Substituting x as -1 in f(x), f(-1)
F(-1)=5(-1)-20
F(-1)=-5-20
F(-1)=-25
Substituting x as2 into g(x), g(2)
G(x) =2^2+5(2)-11
G(x)=4+10-11
G(x)=3
F(-1)+g(2)=-25+3

where r= the radius, and h= the height of the cone. Determine the amount of liquid a paper cone can hold with a 3-inch diameter and a 5-inch height
Answer:
11.78 in³
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3(πr²h)
The cone's radius is half its diameter, so is 1.5 inches. The volume is ...
V = 1/3π(1.5 in)²(5 in) = 3.75π in³ ≈ 11.78 in³
The cone can hold about 11.78 cubic inches of liquid.
