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

548 + 29.5x=2023 should be the answer

($2,023-$548) / $29.50 = 50

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.

What's the slope (0,4) and (-8,-1)

Answers

slope = y2-y1 over x2-x1

-1 - 4= -5

-8-0 - -8

so you get -5/-8

negative divided by negative = positive

slope = 5/8

slope equals to 5/8 since it is rise over run subtract (-1-4) and the divide that by (-8-0)

A 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. Find the time it takes the scond car to reach the first.

Answers

The second car is 30 minutes

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

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

I believe the amount of income tax the doctor has to pay is $9,127.5

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]

The answer is: " [tex] \frac{4}{33} [/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]  .

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

Let x = volume of saline solution A,
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.

18/5 (or 3.6) liters of solution A should be diluted with solution B.

One wintry week a ski town got 15 1/2 inches of snow. On Monday the town got 2 3/4 inches on Tuesday it got 1 1/2 times as much and on Wednesday it got 7/8 inch. How much snow did the town get for the rest of the week

Answers

On Monday the town got 2 3/4 (2.75) inches of snow.
On Tuesday it got 1 1/2 (1.5) times as much: 2.75 x 1.5 = 1.375 (inch)
⇒ On Tuesday the town got 1.375 inch of snow.
On Wednesday it got 7/8 (0.875) inch of snow.
After Monday, Tuesday and Wednesday, the town got:
2.75 + 1.375 + 0.875 = 5 (inches of snow)
For the rest of the week, the town got:
15 1/2 - 5 = 10 1/2 = 10.5 (inches of snow)
