Those values are exact. They approximate to:

10*sqrt(13) = 36.0555

10*sqrt(5) = 22.3607

====================================================

Explanation:

Part (a)

If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.

Apply the pythagorean theorem

a^2 + b^2 = c^2

20^2 + 30^2 = c^2

400 + 900 = c^2

1300 = c^2

c^2 = 1300

c = sqrt(1300)

c = sqrt(100*13)

c = sqrt(100)*sqrt(13)

c = 10*sqrt(13)  .... exact length

c = 36.0555 ...... approximate length

------------------------------------

Part (b)

If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.

Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.

a^2 + b^2 = c^2

20^2 + b^2 = 30^2

400 + b^2 = 900

b^2 = 900-400

b^2 = 500

b = sqrt(500)

b = sqrt(100*5)

b = sqrt(100)*sqrt(5)

b = 10*sqrt(5) ..... exact length

b = 22.3607 .......  approximate length

Answer:

circumference: 37.7

area: 113.1

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04

The individual income tax (or personal income tax) is a tax levied on the wages, salaries, dividends, interest, and other income a person earns throughout the year. The tax is generally imposed by the state in which the income is earned.

Step-by-step explanation:

Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

We have to give that,

To define Payroll tax.

Now, Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

These taxes are withheld to fund various government programs and services.

Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.

The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

These taxes are then remitted by the employer to the appropriate tax agencies on behalf of their employees.

They are specifically related to employment income and play a crucial role in funding important government initiatives and social programs.

When area is dilated you have to multiply the dialation factor by itself, in this case (12 x 12)

Answer:

The monthly cost (in dollars) of a long-distance phone plan is a linear function, which means that the cost is proportional to the total calling time (in minutes). To calculate the monthly cost for 66 minutes of calls, we can use the following equation:

Cost = m * Minutes + b

Where m is the slope of the line, and b is the y-intercept. To find m and b, we can use the two given points: (51, $17.32) and (79, $20.96).

Using the slope formula: m = (20.96 - 17.32)/(79 - 51) = 0.44

We can then use the y-intercept formula: b = 17.32 - 0.44*51 = -4.64

Now we can plug in 66 for Minutes and solve for Cost: Cost = 0.44*66 - 4.64 = $17.12

Therefore, the monthly cost for 66 minutes of calls is $17.12.

Answer:

-2/3n + 7 = 15

-2/3n = 15 + 7

-2/3n = 22

n = 2/3 + 22

n = 24/3

n = 8

Answer:

so we know that the bar in the left represent negative numbers and the bar on the right represents positive numbers.

Step-by-step explanation:

So if I do a problem like 3 to 4 I we would go were is the 3 and go up to 4 putting  a point next to that number which is 4] we would do the same thing over to negative numbers.

The value of x that is reasonable for this situation is 9.73.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the width of locker is x+ 10.

Then, we can consider the length as x.

Now, the area of of door = 192 square inches

So, x(x+10)= 192

x² + 10x = 192

x² + 10x - 192 = 0

Now, using Discriminant Method

x = (-10 ±√ 100 + 768) / 2

x= (-10 ± 868)/2

x= 9.73 or x= -19.73

So, the required value is 9.73 unit.

Answer:

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer:14

Step-by-step explanation:

\(3 \times (4 + 6) - 16 = \)

\(3 \times (10) - 16 = \)

\(3 \times 10 - 16 = \)

\((3 \times 10) - 16 = \)

\(30 - 16 = \)

\(14\)

Answer: d: 34= x + 18

Step-by-step explanation: 34 is the total, and she already made 18. So this means that it would be 34-18=x. OR 18+x=34 which can also be written as 34=18+x

Step-by-step explanation:

Answer:

£320

Step-by-step explanation:

So

The sale price is reduced 40% of the actual price

Actual price - 40% = £192

Actual price is the 100% price of the bike.

100% - 40% = £192

60% = £192

60% of the actual price of the bike is £192 but we need to find 100%.

To do that we need to find the price of 1%. To find this value we divide 60 into 192

\(192 \div 60 = 3.2\)

£ 3.2 is the 1% of the actual price.

To find the actual price (100%), you multiply 3.2 by 100

\(3.2 \times 100 = 320\)

So the actual price is £320

Hope this helps :)

Step-by-step explanation:

£192 = 60% of the original price (reduced by 40%).

1% of the original price = 60%/60 = 192/60 =

= 64/20 = 16/5 = 3.2

100% of the original price = 100×1% = 100×3.2 = £320

the bike cost £320 before the sale.
