Answer:

x = 25

Step-by-step explanation:

The sum of the angles in a triangle are equal to 180 degrees. Since we know the value of one angle is 90 degrees, subtract 90 from 180 to get 90. Now we know the sum of the other two angles must equal 90 degrees. If we add the x and 2x + 15 together, we get 3x + 15 = 90. Subtract 15 from both sides to get 3x = 75. Divide both sides by 3 to get x = 25.

By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L

Relation between ml and litre is that 1 litre =1000 ml

we know that litre and ml are two units of volume and we can convert data from one to another using their relation

Now here given data is in ml

and data is 0.71 ml

We can convert 0.71 ml in litre as

71ml = 0.71/1000 litre

71ml= 0.00071 litre =0.00071 L

By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L

Answer:

  (c)  (4.92, -0.91)

Step-by-step explanation:

The conversion shown in the attached uses the complex number features of the calculator, so the y-coordinate is shown as an imaginary value. Rounded to 2 decimal places the conversion is ...

  (r; θ) ⇔ (x, y)

  (5; 6.1) ⇔ (4.92, -0.91)

__

The correct answer choice can be made without the use of technology. The sum of the magnitudes of the values of x and y must not be less than r, eliminating the first two choices. The angle 6.1 radians is near the angle 6.28 radians (2π), so is almost 360°. It will be a 4th-quadrant angle, so its y-component will be negative (eliminating the last choice).

The only viable choice for polar coordinates of radius 5 and angle 6.1 radians is the third choice: (4.92, -0.91).

Additional comment

The angle given has no units, so we assume it is given in radians. A calculator can only give a proper answer if it is set to radians mode for angles.

Answer: [tex]= 240x^2[/tex]

Step-by-step explanation:

Area of the entire frame = [tex](16x)^2 = 256x^2[/tex]

Area of the mirror = area of a circle = [tex]\pi r^2[/tex]

= [tex]\pi(4x)^2[/tex]

Area of the metal frame surrounding the mirror = square area - circle area

[tex]= (16x)^2-(4x)^2[/tex]

Answer:

If it travels 12.56 ft in one revolution, then the circumference of the tire is 12.56 ft.

Answer:

Miranda. Because she earns $10 per hour while Tommy earns $8 per hour.

Step-by-step explanation:

y = 10x <--- 10 is the amount she earns per every x, which is the number of hours she works.

Tommy's equation is y = 8x

Because if you plug in his values of time (x) and total cash earned (y) you get:

32=?4

Read the above ^ as " 32 = blank multiplied by four "

subtract both sides by four to find blank

Our blank equals 8, which is the amount Tommy makes per hour.

CHECK COMPLETE QUESTION BELOW;

sofia wants to rent an apartment. she visits Apartment a charges $200 for one-time deposit and $400 per month for rent. Apartment b charges $500 for a deposit, but only charges $350 per month in rent. Write in inequality that would determine how many months it would take for cumulative amount paid to be less for apartment b

APARTMENT "A"

✓From the question, the one time charge of appartment "a" = $200

and the monthly rent of the appartment = $400

✓ Let denote the number of months as " y"

We can find the TOTAL COST of the rent for apartment "a" as( 200+400y)

TOTAL COST= (200+400y)

APARTMENT "B"

From the question, the one time charge of the appartment is given as $500,The monthly rent of the appartment is given as $350

The total cost of the rent for the apartment can be expressed as (500+350y)

We need to write and solve an inequality that shows how many months it would take for the total paid to be less for apartment b.

Then the total cost of apartment "a" is less than "b" we can expressed it as;

200+400y<500+350y

Collect like terms, we have

400y-350y<500-200

50y<300

y<6

Hence, it takes less than 6 months it would take for the total paid to be less for apartment b.

Step-by-step explanation:

Formula:

Area of circle = (¶d^2)/4

The circumference of the circle is 106.76 km.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

The diameter of a circle is 34 kilometers.

Diameter of the circle = 34 kilometers

Radius of the circle = Half of diameter = 34 / 2 = 17 km

Circumference of the circle = 2πr, where r is the radius of the circle.

Circumference = 2π × 17

                         = 34π

                         = 106.76 km

Hence the circumference of the circle is 106.76 km.

Answer:

B.

Step-by-step explanation:

Check the picture I have provided for each letter assigned to a shape.

I noted every shape with letters.

A and C are squares and all 3 B's and E are rectangles.

Now we need to calculate the surface area of every shape in order to find out the area of the whole shape.

The surface area of A and C can be found by using the following formula:[tex]s^{2}[/tex] where s means side.

A = 16×16 = 256

C = 16×16 = 256

The surface area of B and E can be found by using the following formula: w×l where w = width and l = length.

A single B = 16×8 = 128

All 3 B's = 128×3 = 384

E = 16×8 = 128

The area of the main shape is = 256+256+384+128 = 1024 square cm.
