Enter your answer in the box
Answers
Answer:
3.29
Step-by-step explanation:
Turn 12% to 0.12.
Multiply 27.44 times 0.12.
Answer:
$24.50
Step-by-step explanation:
Total cost = food cost + (food cost x 12%)
27.44 = x + (x • 0.12)
(rearrange and distribute)
1x + 0.12x = 27.44
(solve for x)
1.12x = 27.44
x = 27.44 / 1.12 = 24.50
Original food cost is $24.50

Coach Brown had to buy baseballs for his team. He bought practice baseballs at $1.75 each, rubber pitching machine balls at $2.80 each, and leather game balls at $6.25 each. He bought 250 balls in total, and 20 fewer game balls than pitching machine balls.
If the total came to $974.65, then how many of each ball were ordered?
A. 130 practice, 113 machine, and 93 game balls
B. 44 practice, 113 machine, and 93 game balls
C. 206 practice, 113 machine, and 93 game balls
D. 114 practice, 113 machine, and 73 game balls
Answers
44 practice, 113 machine, and 93 game balls
===========================================================
Explanation:
x = number of practice baseballsy = number of pitching machine baseballsz = number of game ballsHe bought 20 fewer game balls than pitching machine baseballs, which means,
z = y-20
Since the coach bought 250 baseballs total we can also write
x+y+z = 250
Let's replace z with y-20 and simplify
x+y+z = 250
x+y+y-20 = 250
x+2y = 250+20
x+2y = 270
Now let's calculate the subtotal costs for each type of baseball
1.75x = cost of just the practice baseballs2.80y = cost of just the pitching machine baseballs6.25z = cost of just the leather game balls.Those subtotals add to this
1.75x+2.80y+6.25z = total cost = $974.65
1.75x+2.80y+6.25z = 974.65
Like before, I'll replace z with y-20
1.75x+2.80y+6.25(y-20) = 974.65
1.75x+2.80y+6.25y-125 = 974.65
1.75x+9.05y = 974.65+125
1.75x+9.05y = 1099.65
------------------------------
So far we have this system of equations
[tex]\begin{cases}x+2y = 270\\1.75x+9.05y = 1099.65\end{cases}[/tex]
I'll use substitution to solve the system.
Isolate x in equation (1)
x+2y = 270
x = 270-2y
Then plug this into equation (2) and solve for y.
1.75x+9.05y = 1099.65
1.75(270-2y)+9.05y = 1099.65
472.5-3.5y+9.05y = 1099.65
472.5+5.55y = 1099.65
5.55y = 1099.65-472.5
5.55y = 627.15
y = 627.15/5.55
y = 113
There are 113 pitching machine baseballs.
Use this y value to find x
x = 270-2y
x = 270-2(113)
x = 270-226
x = 44
There are 44 practice baseballs.
Also, we can say,
z = y-20
z = 113-20
z = 93
There are 93 game balls.
------------------------------
Check:
x+y+z = 44+113+93 = 250 baseballs total
A = 1.75*x = 1.75*44 = 77 = cost of just the practice baseballsB = 2.80*y = 2.80*113 = 316.40 = cost of just the pitching machine baseballsC = 6.25*z = 6.25*93 = 581.25 = cost of just the game ballsA+B+C = 77+316.40+581.25 = 974.65 = total cost
Everything checks out. Also note that value of z is 20 fewer than the value of y.

To convert a temperature measured in degrees Fahrenheit to degrees Celsius, there is a formula
C=5/9(F-32)
where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.
If a temperature is 113`F, what is that temperature measured in Celsius?
Answers
Answer:
113`F= 46.11° Celsius
Step-by-step explanation:
(Celsius°C × 9/5) + 32 = Fahrenheit
(Celsius°C × 9/5) + 32 = 113
(Celsius°C × 9/5) = 113 - 32
(Celsius°C × 9/5) = 83
Celsius = 5(83)/9
Celsius = 46.11° Celsius
[tex]\\ \tt\hookrightarrow C=5/9(F-32)[/tex]

(ii) How much does he save in a month ? (iii) How much does he save in 1 year ? (iv) If he spends 80% of his annual saving to buy a piece of land, What is the cost of the land ?
Answers
Answer:
a) i) Rs 8,640
ii) Rs 12,960
iii) Rs 155,520
iv) Rs 124,416
Step-by-step explanation:
Salary = Rs 21,600 per month
a) i)
Percentage of salary spent on education = 15%
⇒ 15% of 21600 = 0.15 x 21600 = 3240
Percentage of salary spent on food = 25%
⇒ 25% of 21600 = 0.25 x 21600 = 5400
Therefore, total monthly expenses = 3240 + 5400 = 8640
ii) Monthly savings = monthly salary - monthly expenses
= 21600 - 8640
= 12960
iii) 1 year savings = monthly savings x 12
= 12960 x 12
= 155520
iv) 80% of savings = 0.8 x 155520 = 124416

A bike was recently marked down $200. 00 from its initial price. If you have a coupon for an additional 30% off after the markdown, how much will the bike cost if it was originally $950. 00?.
Answers
Percentage is represented by '%' symbol. The final cost of the bike will be equal to $490.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
Given to us
The initial cost of the bike, P = $950
Additional coupon = 30%
Marked down = $200
We know the original cost of the bike which is $950. therefore, when the price of the bike was marked down, its cost will be,
$900 - $200 = $700
Thus, the marked-down cost of the bike will be $700.
As it is given that we have an additional 30% off after the markdown, therefore, cost of the bike will be 70% of the marked price,
[tex]70\%\ of\ \$700\\\\ = 0.70 \times 700\\\\= \$490[/tex]
Hence, the final cost of the bike will be equal to $490.

Answers
Answer:
mean : 55; median : 53
Step-by-step explanation:
Given inputs: 68, 41, 58, 75, 48, 40
total numbers of input = 6
total value = 68 + 41 + 58 + 75 + 48 + 40 = 330
Mean → total value / total numbers of input = 330 / 6
= 55
arrange in increasing order: 40, 41, 48, 58, 68, 75
we can see that the median is between, 48 and 58,
