On a certain hot​ summer's 439 day, people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $1021.00 How many children and how many adults swam at the public pool that​ day?

Answers

Answer:102 children and 337 adults swam at the publice pool that da

Step-by-step explanation:

let the number of children be x

and

the number of adults be y

such that the total number of people who came to use the public swimming pool be expressed as

x + y = 439----- Equation 1

and price  for swimming be expressed as

1.75x + 2.50y =1021----- Equation 2

Step 2

x + y = 439----- Equation 1

1.75x + 2.50y =1021----- Equation 2

First make x the subject formulae and put in equation 2

x= 439-y

1.75 (430-y) + 2.50y = 1021

Solving gives

768.25-1.75y+2.50y=1021

2.50y-1.75y=1021-768.25

0.75y=252.75

y =252.75/0.75  

y=337

To find x, put the value of y = 337 in equation 1

x+y= 439

x= 439-337

x=102

Therefore 102 children and 337 adults swam at the public pool that day

The measure of angle JLM is 140°. The measure of angle JKL is 75.

What is the measure of angle KJL

Enter your answer in the box.​

Answers

Answer:

KJL is 65 degrees

Step-by-step explanation:

If JLM is 140 deg. JLK is 40 deg  the two angles on transverse line must equal 180 total.

JKL being 75 degf, sum that with JLK of 40= 115 deg

180-115= 65 deg  Sum of interior angles on a triangle add up to 180 deg.

At least that is how I remember it, you can also graph it and check it out.

Circle theorems please help

Answers

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = [tex]\frac{1}{2}[/tex] (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28

Sal places $500 in a retirement account that offers a return of 3.5% compounded annually . He will not deposit or withdraw any money from the account . Which function represents f(t) , the amount of money in the account after years a f(t) = 500 * (0.035) ^ t c. F(t) = 500 + 0.035t f(t) = 500 * (1.035) ^ t d. F(t) = 500 + 1.035t

Answers

Answer:

f(t) = 500 * (1.035) ^ t

Step-by-step explanation:

A = p(1 + r/n)^nt

Where

A = future value = ?

P = principal = $500

r = interest rate = 3.5% = 0.035

n = number of periods = 1

t = number of years = t

A = p(1 + r/n)^nt

= 500(1 + 0.035/1)^1*t

= 500(1 + 0.035) ^t

= 500( 1.035)^t

= 500 * (1.035)^t

f(t) = 500 * (1.035) ^ t
