The swimming team has competed in 45 races this season. They have won 30 races so far. How many races will the team need to win today for the team to have a 75% success rate? 8 10 12 15.

Answers

Answer 1

The number of races the team need to win today for the team to have a 75% success rate is 15

Number of attempt = 45

Number of winnings = 30

Percentage won so far = 30/45 × 100

= 66.67%

let

x = Number of races that tfe team needs to win to have 75% success rate

(30 + x) / (45 + x) = 0.75

Cross product

30 + x = 0.75(45 + x)

30 + x = 33.75 + 0.75x

x - 0.75x = 33.75 - 30

0.25x = 3.75

x = 3.75 / 0.25

x = 15

Therefore, the number of races the team need to win today for the team to have a 75% success rate is 15

[] To round, we look at the number right the place. If it is less than 5, keep it the same. If it is five or greater , round up.

[] In this case it is a 3, so we keep it the same. We get an answer of 68,500

     I hope this is what you are looking for, but if not - comment! I will edit and update  my answer accordingly. (ノ^∇^)

The answer is:

68,500

Explanation:

When counting, the digit 5 is in the hundredth place in the entire number.

For example:

$500 (five hundred dollars)
$6,500 (six thousand, five hundred dollars).

Therefore, whatever comes after the number 5 would become a zero.

a box of snacks contained 20 individual packages. the newly designed box contains 28 individual packages by what percent did the individual packages increase

Answers

Answer:

40%

Step-by-step explanation:

increased amount = 28 - 20 = 8

to get the percentage we have to divide the increased amount by original amount which will be 8/20 = 0.4

0.4 is 40%

The percentage increase is given as:

= [ (Final value - Initial value) / Initial value] x 100

The percentage increase in the number of individual packages is 40%

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Number of initial individuals packages = 20

Number of final individuals packages = 28

The percentage increase is given as:

= [ (Final value - Initial value) / Initial value] x 100

The percentage increase in the number of individual packages:

= [(28 - 20) / 20] x 100

= (8/20) x 100

= 40%

We can cross-check:

100% = 20 packages

140% = 140/100 x 20 packages

140% = 28 packages.

Thus,

The percentage increase in the number of individual packages is 40%

y=120+30

y=150 - Therefore, the water temperature will be 150°C after 12 minutes

Let cost of watch=w
Let cost of watch=r

w+r=500
but w=r-150

So;r-150+r=500
2r=500+150
2r=650
r=650/2
r=325

If r=325,
then w+r=500
w+325=500
w=500-325
w=175

Cost of watch=rs175
Cost of radio=rs325

= 5(2h) + 5(8) < 60

SUBTRACT 40 to BOTH SIDES

= 10h + 40 - 40 < 60 - 40

CANCEL out: 40 - 40 because it gives you 0

KEEP: 60 - 40 because it helps solve for the h-value.

Area of the figure = Area of the rectangle+Area of the trapeziumA = aw+h(a+b)/2..................... Equation 1

Where:

a = Length of the rectangle = Length of on of the side of the trapezium = 10 inb = Length of the other side of the trapezium = 6 inh = Height of the trapezium = 5 inw = Width of the rectangle = 5 in
