A quadrilateral with all sides is equal, opposite angles are congruent and diagonals bisected each at a right angle.

Answer:

B. 40

Step-by-step explanation:

It looks like a 90-degree angle so...

90 - 30 = 60

60 - 20 = 40

40 would be your final answer.

Answer:

Breadth = 12 m

Step-by-step explanation:

Area of a rectangle is given by the formula,

Area = Length × Width

Value of area and length of the rectangular park has been given in this question.

Therefore, by substituting these values in the formula,

300 = 25 × Width

Width = [tex]\frac{300}{25}[/tex]

          = 12 m

Therefore, width or breadth of the rectangular park will be 12 m.

Answer:

A: 171.75

B: 170

Step-by-step explanation:

The mean (or average) can be found by...

- add all the numbers together (we will call this y)

- divide the total sum (or y) by the total amount of numbers used to add

Formula:

(x₁ + x₂ + x₃ + ... + xₙ) ÷ n

For A:

(172 + 130 + 173 + 212) ÷ 4 = 171.75

For B:

(136 + 184 + 168 + 192) ÷ 4 = 170

Answer:

C) 15% off with a $15 rebate

Step-by-step explanation:

So a rebate is like a refund which means:

A) 120(.8) = 96         You use .8 because you’re paying 80%

B) 120-30= 90

C) 120(.85) = 102     you use .85 because you’re paying 85%, now

 102-15= 87         Subtract 15 since you get a $15 rebate

D) 120(.9)=108   You use .9 since you are paying 90%

    108-20= 88    Subtract 20 since you get a $20 rebate

since C ended up with the lowest price, the answer is C

Answer:

3.04 units

Step-by-step explanation:

h = volume / (3.14 x r^2)

86 / (3.14 x 3^3) = 3.04 units

Answer:

16.07 milligrams

Step-by-step explanation:

From the question,

Using the formula of radioactive decay,

R/R' = 2ᵃ/ᵇ..................... Equation 1

Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.

Make R' the subject of the equation

R' = R/(2ᵃ/ᵇ)................ Equation 2

Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days

Substitute these values into equation 2

R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)

R' = 100/(6.222)

R' = 16.07 milligrams of plonium-210

Answer:

The answer is "It must be shown that both [tex]j(k(x))\ and \ k(j(x))=x[/tex]"

Step-by-step explanation:

Given:

[tex]j(x) = 11.6 e^{x} \\\\k(x) =\ln\frac{x}{11.6}[/tex]

To show that both are equal functions, and  show that both[tex]j(k(x))\ and\ k(j(x)) =x,[/tex]

For [tex]j(k(x));[/tex]  

[tex]j(k(x)) = j[(\ln \frac{x}{11.6})]\\\\j[(\ln (\frac{x}{11.6})] = 11.6e^{\ln (\frac{x}{11.6})}\\\\j[(\ln \frac{x}{11.6})] = 11.6(\frac{x}{11.6})\\\\[/tex](The natural logarithm is canceled by exponential function)  

[tex]j[(\ln \frac{x}{11.6})] = 11.6 \times\frac{x}{11.6}\\\\j[(\ln \frac{x}{11.6})] = x\\\\j[k(x)] = x\\\\for\ \ k[j(x)]:\\\\k[j(x)] = k[11.6e^x]\\\\k[11.6e^x] = \ln (\frac{11.6e^x}{11.6})\\\\k[11.6e^x] = \ln(e^x)[/tex]

Its natural logarithm leaving x will nullify expanding universe.

[tex]k[11.6e^x] = x\\\\k[j(x)] = x[/tex]

In the question, it is seen that[tex]j[k(x)] = k[j(x)] = x[/tex], shows that the functions [tex]j(x) = 11.6 e^{x} \ and \ k(x) = \ln \frac{x}{11.6}[/tex] is inverse functions.

Answer:

There are 3,750 sweets in the carton

Step-by-step explanation:

Here, we want to get the total number of sweets

From the question, we have that individual box have 50 sweets

So the number of sweets in the carton have 75 boxes will be the product of the number of sweets and the number of boxes

Mathematically, we have this as;

50 * 75 = 3,750 sweets

Answer:

x=2√5

Step-by-step explanation:

1st method:

sin(30)=opposite/hypotenuse=√5/x

sin(30)x=√5

x=√5/sin(30)

x=2√5

2nd method:

cos(60)=adjacent/hypotenuse=√5/x

cos(60)x=√5

x=√5/cos(60)

x=2√5

3rd method:

This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5

Answer:

Answer:

(3x-7) (x+1)

Step-by-step explanation:

3x^2 - 4x - 7

First split the middle term

3x^2 + 3x - 7x - 7

Make into two separate expressions

(3x^2 + 3x) (-7x-7)

Take out what you can

3x (x+1) -7 (x+1)

Now you have your answers

(3x-7) (x+1)

The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

here, given that,

Round 245,675 to the nearest hundred thousand

we know,

Anything at or above 50 gets rounded up.

49 and below gets rounded down.

so, we get,

here, to the nearest hundred thousand means 675 > 500

so, it will be 5,675 => 6000

we have,

Rounding off 245,675 to the nearest hundred thousand is:

246000

Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Answer:

30%

Step-by-step explanation:

Find the percent discount by dividing the change in the price by the original price:

(684 - 478.6) / 684

205.4 / 684

= 0.3

So, the percent discount was approximately 30%
