Find the radius of the circle which has the same area
as the combined area of a circle of radius 12 cm and a
circle of radius 5 cm.​

Answer:

-21 degrees

Step-by-step explanation:

-8+(-13)=-21

Answer:

Step-by-step explanation:

5)

21x + 4 = 22x - 2

6 = x

6)

x + 72 + x + 132 = 180

2x + 204 = 180

2x = -24

x = -12

7)

22x + 2 = 90

22x = 88

x = 4

8)

12x + 10 = 13x + 3

7 = x

9)

17x = 16x + 5

x = 5

17(5) = 85°

10)

20x = 21x - 6

-x = -6

x = 6

20(6) = 120º

Answer:

hi

Step-by-step explanation:

Answer:

$12500

Step-by-step explanation:

Given that:

Salary plan 1:

Weekly salary of $500.

And a commission of 4%.

Salary plan 2:

Straight commission of 8%.

To find:

Weekly sales for which both the plans will make the same sales?

Solution:

Let the weekly sales = $[tex]x[/tex]

As per question statement:

Salary as per Plan 1 = $500 + 4% of [tex]x[/tex]

Salary as per Plan 2 = 8% of [tex]x[/tex]

Putting both the salaries to equal to find the total weekly sales.

$500 + 4% of [tex]x[/tex] = 8% of [tex]x[/tex]

[tex]\Rightarrow 500 = 4\%\ of\ x\\\Rightarrow 500 = \dfrac{4}{100}x\\\Rightarrow x = \$12500[/tex]

Therefore, the answer is:

For the sales of $12500, the salary will be same from both the plans.

Answer:

4.11 cups of skim milk

Step-by-step explanation:

You can get the answer by knowing the value of a cup in milliliters first.

Let's convert 3.58 cups to ml by using the multiplication operation.

895 ml is 87% of skim milk.

Let's convert this into an equation. Let x be the amount of skim milk.

895 = 87% of x

895 = 0.87(x)

x = [tex]\frac{895}{0.87}[/tex]

x = 1,028.73 ml

Now that we know the amount of skim milk, let's convert it to cups.

1,028.73 ml ÷ 250 ml = 4.11 cups

Let's check.

4.11 cups of skim milk contain 3.58 cups of water.

Given,

Skim milk contain water is 87% of water = 0.87

We have to find ,

Total no. of Cups of skim of milk 3.58 cups of water.

According to the question .

The value of a cup in milliliters first.

We know that ,

1 cup = 250 ml  

Let's convert 3.58 cups to ml  

3.58 x 250 = 895 ml

895 ml is 87% of skim milk.

Let's convert this into an equation. Let x be the amount of skim milk.

895 = 87% of x

895 = 0.87(x)

[tex]x = \frac{895}{0.87}[/tex]

x = 1,028.73 ml

To know the amount of skim milk, let's convert it to cups.

1,028.73 ml ÷ 250 ml = 4.11 cups

The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

Given the preimage of a parallelogram with vertices (1,5), (3,3), (3,7), and (5,5).

If we plot in the coordinate plane as shown below.

Now plot the image of a parallelogram with vertices (−5,3), (−3,1), (−3,5), and (−1,3).

If we take only one vertex of the preimage to let's say (1,5) now if we look at the corresponding vertex in the image then it is (-5,3).

1 + x = -5 ⇒ x = -6 (6 units left)

5 + y = 3 ⇒ y = -2 (2 units down)

Hence "The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram".

Answer:

Solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

Step-by-step explanation:

We need to solve the equation [tex]15 = 3n + 6p[/tex] for variable n

Solving:

[tex]15 = 3n + 6p[/tex]

Subtract both sides by 6p

[tex]15-6p = 3n +6p -6p\\15-6p=3n[/tex]

Switch sides of equality

[tex]3n=15-6p[/tex]

Divide both sides by 3

[tex]\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p[/tex]

So, solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

Answer:

$150

Step-by-step explanation:

Given

Delivery amount = $120

Percent tip on the delivery amount = 15%

Tip amount = 15% * 120

Tip amount = 0.15 * 120 = $30

Total money paid = Delivery amount + Tip

Total money paid  = $120 + $30

Total money paid = $150

hence the total money you will give the delivery boy is $150

Answer: Answer: 2.0111 × 100 square kilometers (km²)

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x - 10 ← is in slope- intercept form

with slope m = 7

Parallel lines have equal slopes, thus

m = 7 and point on line is T(- 3, 3 )

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line, then

y - 3 = 7(x - (- 3) ), that is

y - 3 = 7(x + 3) → D

Answer:

A is 30 degrees.

Step-by-step explanation:

cot A = 1/ tan A

Therefore 3 tan A = 1 / tan A

3 tan^2 A = 1

tan^2 A = 1/3

tan A = 1 /√3   is A is acute.

A = 30 degrees.

This is about trigonometric identities.

A = 30°

Tan A = sin A/cos A

Cosec A = 1/sin A

Sec A = 1/cos A

Cot A = 1/tan A

3 tan A = cot A

But we know from above that Cot A = 1/tan A

Thus;

3 tan A = 1/tan A

Rearranging to get;

(tan A)² = 1/3

tan A = √(1/3)

tan A = 1/√3

sin 30° = cos 60° = 1/2

sin 60° = cos 60° = (√3)/2

sin 45° = cos 45° = 1/√2

tan 30° = 1/√3

tan 60° = √3

tan 45° = 1

A = 30°

A is said to be an acute angle which means it is less than 90° and so it is correct.

This is the answer.

In case your expression is:

[tex]x^2\:-\:xy\:+\:x^2\:-\:xy[/tex]

Solution:

Given the expression

[tex]x^2\:-\:xy\:+\:x^2\:-\:xy[/tex]

Group like terms

[tex]x^2\:-\:xy\:+\:x^2\:-\:xy=x^2+x^2-xy-xy[/tex]

Add similar elements: x²+x² = 2x²

Add similar elements: -xy-xy = -2xy

                                    [tex]=2x^2-2xy[/tex]

Thus,

[tex]x^2-xy+x^2-xy=2x^2-2xy[/tex]

In case your expression is:

Answer:

Step-by-step explanation:

Given that:

Price of car = $18,936

Upfront paid = $3000

Time taken to pay remaining balance = 4 years

Amount paid per month if the same amount is paid per month

Remaining balance :

($18,936 - $3000) = $15,936

Number of months in 4 years = (12 * 4). = 48 months

Amount paid per month :

$15,936 / 48

= $332
