A school bought $548 in basketball equipment and uniforms costing $29.50 each. The total cost was $2,023. Write an equation you can use to find the number of uniforms the school purchased.
Answers
What the equation means: Since we already know they spent $548 in basketball equipment, we can subtract that from the total cost to find out how much they spent for the uniforms. After that, we have to divide the money used to buy the uniforms by the cost of each uniforms. Your final answer would be 50 uniforms.

Saline solution A is 10% strength and saline solution B is 5% strength. I have an order for 6 litres of an 8% saline solution. To fill the order how many litres of solution A should be diluted with solution B? (Hint. Assume a 1% solution contains r grams of salt per litre.)
Answers
y = volume of saline solution B.
We're going to set up two equations.
Firstly, x + y = 6. That gives us y = 6 – x (1)
Second, 0.1x + 0.05y = 0.08•6,
or 0.1x + 0.05y = 0.48 (2)
Substitute (1) into (2):
0.1x + 0.05(6 – x) = 0.48
0.1x + 0.3 – 0.05x = 0.48
0.05x + 0.3 = 0.48
Subtract 0.3 from both sides:
0.05x = 0.18
x = 3.6
Then y = 6 – 3.6 = 2.4
So we have to use 3.6 litres of solution A and 2.4 litres of solution B.

A doctor has an annual income of $152,125. The income tax the doctor has to pay is 6% , what is the amount of income tax in dollars and cents that the doctor has to pay ?
( this is a griddable question by the way )
Answers
Answer:
The amount of income tax is $9127.50 or 912750 cents.
Step-by-step explanation:
Amount of annual income = [tex]\$152,125[/tex]
Rate of income tax = [tex]6\%[/tex]
So, the amount of income tax in dollars
[tex]= 6\%[/tex] of [tex]\$152,125[/tex]
[tex]=(\frac{6}{100}\times \$152125 )= \$9,127.50[/tex]
and in cents [tex]=(9127.50\times 100) cents = 912750cents[/tex]

______________________________
Given: 0.1212121212..... repeating ; write that value as a fraction;
______________________________________________________
In other words; we are given: "0.1212121212..... repeating infinitely" ;
→ that is to say; "0.12 ... ; {the "12" decimal portion repeats infinitely} ;
_______________________________________________________
→ We write this value, as a fraction, as: "12/99" ;
__________________________________________
→Explanation:
__________________________________________
Note: "0.99999999...... repeating infinitely; = "1" .
_________________________________________
→Since:
Let us say that we have:
"x = 0.999999 ; repeating infinitely;
In order words, let us say we have: "x = 0.9.... ; the "9" decimal repeats infinitely;
_____________________________________________________
Then "10x" ; (that is: "10" multlipled by "x"; or "10*x" or "10x" ); is equal to:
"10" * (0.999999.....) = 9.99999999...... (the "9" decimal repeats infinitely);
in other words: 10x = 9.99999999....
Divide each side by "10" ;
to get "x = 0.9999999....." ; the decimal "9" repeats indefinitely...." ;
But if you have: "10x = 10" ; divide each side of the equation by "10" ;
you get: "x = 1" .
____________________
Also, if "x = 0.9999...(repeating infinitely);
then: 10x = 9.99999.
_______________________________________________
10x = 9.999999999999999......
− x = 0.999999999999999.......
_____________________________________
9x = 9.00000000000000000000.....
→ 9x = 9 ;
Divide each side of the equation; to get;
9x /9 = 9/ 9 ; to get: x = 1 ; and we have: x = 0.9999.... ; so
x= 0.99999.... = 1 ;
__________________________________________________
So, if the numbers "12" is repeating, we divie "12" by "99" ;
that is; we divide "12" by "two 9's" ; since "12" is a "TWO-digit number"; a "two-digit number" is being repeated infinitely.
________________________________________
So; 0.12121212.....(the "12" is the decimal that repeats infinitely);
= 12/99 ; which can be simplified;
Divide each side (both the numerator AND the denominator); by "3" ;
_________________________________________
" 12/99 " = "(12÷3) / (99÷3) = 4/33 " .
_________________________________________
The answer is: [tex] \frac{4}{33} [/tex] .

During a canned food drive, Bob collected 6 times as many cans as Tom. If t represents the number of cans that Tom collected, which algebraic expression represents the number of cans that Bob collected?
Answers
The algebraic expression that represents the number of cans that Bob collected, given that t represents the number of cans that Tom collected, is 6t.
Explanation:The algebraic expression that represents the number of cans that Bob collected, given that t represents the number of cans that Tom collected, is 6t. Since Bob collected 6 times as many cans as Tom, we can multiply the number of cans Tom collected by 6 to get the number of cans Bob collected.
If Bob collected 6 times as many cans as Tom, and if we represent the number of cans Tom collected with the variable t, then the algebraic expression that represents the number of cans that Bob collected is 6t. This is because if Tom collected t cans, then Bob, having collected 6 times more, would have collected 6 multiplied by t, which is simply represented as 6t.
The algebraic expression that represents the number of cans that Bob collected is 6t.
Explanation:The algebraic expression that represents the number of cans that Bob collected is 6t. Since Bob collected 6 times as many cans as Tom, we can represent the number of cans that Bob collected by multiplying Tom's number of cans by 6. Hence, if t represents the number of cans that Tom collected, the expression 6t represents the number of cans that Bob collected.

Answers
The time it takes the second car to reach the first is 9 hour.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken
We are given that car leaves a city with a speed of 90 mph. Three hours later and our of the same city another car in pursuit of the first leaves with a speed of 120 mph.
Consider t be the time since the first car leaves
Distance of first car = 90t
Distance of second car:
120(t - 3)
Therefore, 90t = 120(t - 3)
90t = 120t - 360
360 = 30t
t = 12
The second car takes 12-3 = 9 hours to reach it
