Answer:

Lets firts mention that the rule presented in the question does not apply for all real numbers

But, we can see that in some cases it might be true.

Let

a = 1

b = 0

√1 + √0  = 1 + 0 = 1

Likewise,

√(1 + 0)  =  √(1) = 1

And we see that the result is the same.

Answer:

πx miles

Step-by-step explanation:

Given in the question,

radius of a circle = x/2 miles

To find circumference of a circle we will use following formula

2π * r

where π is constant = 3.14

            r is radius of circle

Plug values in the formula

2(3.14)(x/2)

2 will cancel out

30k just multiply the 2 by 15 and get 30k

Answer:

9√3 unit^2.

Step-by-step explanation:

The area  = 1/2 6^2 sin 60

= 1/2 * 36 * √3/2

= 9√3

The area is [tex]9\sqrt{3}un^2.[/tex]

Note that: triangle AOB is an equilateral triangle because:

OA = OB (both are radius)

So ∠OAB = ∠OBA

Given that ∠AOB=60 degree.

The sum of three angles of a triangle is 180 degrees.

So,

∠OAB + ∠OBA + ∠AOB = 180

∠OAB + ∠OBA + 60 = 180

∠OAB + ∠OBA = 120

∠OAB + ∠OAB = 120

2∠OAB = 120

∠OAB = 60

It means ∠OAB = ∠OBA  =60.

Since all the angles of these triangle is 60 degree, so triangle AOB is an equilateral triangle.

Given: side length = a = 6.

The area of the triangle is: [tex]\frac{\sqrt{3}}{4}a^{2}=\frac{\sqrt{3}}{4}\left(6^{2}\right)=\frac{\sqrt{3}}{4}\left(36\right)=9\sqrt{3}[/tex]

Answer:

the amount the grocer spend on marketing last year = $ 1048.38

Step-by-step explanation:

To find the budget we will subtract the current marketing budget number from 100

As 38% = 0.38

i.e, 100 - 0.38= 0.62

Now divide the previous year budget amount percentage found by the amount spent this year

=650 / 0.62

= 1048.38

Final answer:

To find out how much the grocer spent on marketing last year, divide the current amount he spent by the remaining percentage of the original amount before the cut.

Explanation:

To find out how much the grocer spent on marketing last year, we need to determine the original amount before the 38% cut. Let's assume the original amount is x. If the grocer cut the marketing budget by 38%, it means he spent 100% - 38% = 62% of the original amount. The equation can be set up as: 0.62x = $650. To solve for x, divide both sides of the equation by 0.62. So, x = $650 ÷ 0.62 = $1048.39.

product is the answer to a multiplication problem mx6=90

The sentence 'The product of Mabel's score and 6 is 90' translates into the equation 'm * 6 = 90' in mathematics, where m represents Mabel's score.

The sentence provided can be translated into an equation. In mathematics, the phrase 'the product of' means to multiply. Here, Mabel's score is represented by the variable m. The 'product of Mabel's score and 6' is the same as saying 'm multiplied by 6'. This is said to be equal to 90. Therefore, the equation that represents this sentence is m * 6 = 90.

To translate the sentence 'The product of Mabel's score and 6 is 90' into an equation using the variable m to represent Mabel's score, we can write:

6m = 90

This equation states that the product of Mabel's score (m) and 6 is equal to 90.

Is 34 the diameter or radius?

the area of ABCD is 135

Answer:

2212.5 cm²

Step-by-step explanation:

ABCD is constructed from 2 right triangles ABD and BCD

The area (A ) of a triangle is calculated using the formula

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

In ΔABD, b = AD = 60 and h = AB = 25, hence

A = [tex]\frac{1}{2}[/tex] × 60 × 25 = 30 × 25 = 750 cm²

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

In ΔBCD, b = BD = 65 and h = CE = 45, hence

A = [tex]\frac{1}{2}[/tex] × 65 × 45 = 1462.5 cm²

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

The area of figure ABCD = area of ΔABD + area of ΔBCD

A = 750 + 1462.5 = 2212.5 cm²

Answer: 26.8 feet

Step-by-step explanation:

In the figure attached you can see two right triangles  triangle ABD and a triangle ACD.

You are located at point B and the other person at point C.

The approximate height of the lifeguard station is x.

Keep on mind that:

[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]

Therefore:

For the triangle ABD:

[tex]tan(36\°)=\frac{x}{DC+11}[/tex]    [EQUATION 1]

For the triangle ACD:

[tex]tan(46\°)=\frac{x}{DC}[/tex]    [EQUATION 2]

Solve from DC from [EQUATION 2]:

[tex]DC=\frac{x}{tan(46\°)}[/tex]

Substitute into [EQUATION 1] and solve for x:

[tex]tan(36\°)=\frac{x}{(\frac{x}{tan(46\°)}+11)}\\tan(36\°)(\frac{x}{tan(46\°)}+11)=x\\11*tan(36\°)=x-\frac{xtan(36\°)}{tan(46\°)}\\7.991=0.298x[/tex]

Answer:

0.266

Step-by-step explanation:

Total No of seats in class = 8+10+12 = 30

probability that first student will be assigned first row will be: 8/30 = 0.266

because there are 8 front row seats and total seats are 30.

The probability that the first student who enters the classroom will be assigned a seat in the front row is; Option D; 4/15

We are told;

Number of front row seats = 8 seats

Number of middle row seats = 10 seats

Number of back row seats = 12 seats

Thus;

Total number of seats in classroom = 8 + 10 + 12

>> 30 seats

Now, we want to find the probability that the first student who enters the classroom will be assigned a seat in the front row.

Thus;

P(1st student sits in front row) = 8/30

This can be reduced to get;

P(1st student sits in front row) = 4/15

C ($6,250)

Step-by-step explanation:

25 cartons with 5 stereos per carton=125 stereos total

profit for one stereo=80-30=50

125*50= 6250

After selling all the stereos, the company's profit will be $ 6250.

Profit is considered as the gain amount from any business activity. Whenever a shopkeeper sells a product, his motive is to gain some benefit from the buyer in the name of profit.

Here, Ray have 25 cartons with 5 stereos per carton

          So total Ray have,  25 X5 = 125 stereos

      profit on one stereo = 80 - 30 = $50

        Total profit on 125 stereos = 125*50=  $ 6250

Thus, after selling all the stereos, the company's profit will be $ 6250.

Answer: 1/5

Step-by-step explanation:

Answer:

1/500

Step-by-step explanation:

if you add a %, multiply the number by 100 (or move to the right 2 decimal places)

if you remove the %, divide the number by 100 (or move to the left 2 decimal places)

example .5 to a percent is .5(100) = 50%

to make this a fraction, first change the number to a decimal, then divide by 100, or multiply by 1/100.  

.20 is the fractional number of two tenths or 2/10%.  

(2/10)(1/100)  = 2 / 1000    this can reduce to 1/500
