[tex]\angle A + \angle B + \angle C = 180[/tex] (angles of a triangle sum to [tex]180^{\circ}[/tex])

[tex]\angle A + 100 + 30 = 180[/tex]

[tex]\angle A = 50^{\circ}[/tex]

Circumference = Perimeter

Perimeter of Circle

= 550cm

Also,

Perimeter of Circle

= 2πr

Now,

2πr = 550

πr = 550/2

πr = 275

r = 275/π

r = 275/ 22/7

r = 275 × 7/22

r = 87.5cm

Answer:

Step-by-step explanation:

using the formula of slope Y2-Y1/X2- X1

The measurement which is closest to the  height of this cylinder is: C. 48 in.

Given the following data:

To determine the measurement which is closest to the  height of this cylinder in inches:

Mathematically, the volume of a cylinder is given by the formula:

[tex]Volume = \pi r^2h[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]8478 = 15^2h\\\\8478 = 225h\\\\h=\frac{8478}{225}[/tex]

Height, h = 37.38 inches.

Closest height = 48 inches.

Answer:

=3x^2\left(3+x\right)

Step-by-step explanation:

There is a circumference of 69.167 miles per degree of latitude.

Firstly, we assume that the earth is a spherical form to simplify calculations as spheres have constant radii of curvature, because the real form of the planet is similar to a oblate spheroid, a kind of ellipsoid. In addition, the circular arc (s), in miles, is directly proportional to the measure of the central angle (θ), in degrees, that is:

s ∝ θ

s = k · θ         (1)

Where k is the constant of proportionality, in miles.

Now we eliminate the constant of proportionality and we calculate the circular arc afterwards:

s / 24900 mi = 1° / 360°

s = 1 / 360 × 24900 mi

s = 69.167 mi

There is a circumference of 69.167 miles per degree of latitude.

Answer:

Investment A = 3650

Investment B = 1350

Step-by-step explanation:

Given that:

Total interest earned = 332.50

Total Principal invested = 5000

Investment A:

Rate = 8%

Time = 1 year

Principal = a

Interest earned = 0.08a

Investment B:

Rate = 3%

Time = 1 year

Principal = b

Interest earned = 0.03b

a + b = 5000 ____(1)

0.08a + 0.03b = 332.50 - - - (2)

From (1)

a = 5000 - b

Into (2)

0.08(5000 - b) + 0.03b = 332.50

400 - 0.08b + 0.03b = 332.50

400 - 0.05b = 332.50

-0.05b = - 67.5

b = $1350

a = 5000 - b

a = 5000 - 1350

a = $3650

( 7 , 8) ( 9 , 14)

x1 y1. x2 y2

Answer: (I worked left-right instead of column 1, then column 2. That's why the answers are jumbled up. 2 on my work corresponds to 4 in the pic, 3 corresponds to 2, 4 corresponds to 5, and 5 corresponds to 3.)

1. 75 degrees

2. 112 degrees

3. 89 degrees

4. x is 8, so 111 degrees

5. x is 3 in both cases, so 90 degrees each

6. x is -7, so 130 degrees

Step-by-step explanation:

1. Adjacent angles are the same measurement. Since the one labeled is 75 degrees, and the question marked angle is adjacent, it is also 75 degrees.

2. The angles shown are complementary, so they both equal 180 degrees. To find the angle marked with "?", subtract 68 from 180 for 112 degrees.

3. The angle labeled is 89 degrees. The one labeled with "?" should be the same, as it is below it, and on the same point as the labeled one. So, 89 degrees is the measurement.

4. The labeled angle is 69 degrees. 180 - 69 is 111 degrees. The equation shown now becomes 12x + 15 = 111. 111 - 15 is 96, which means 12x = 96. Divide both sides by 12 to get x equalling 8.

5. These lines are all perpendicular, so they're all 90 degrees. 29x + 3 = 90, and 31x - 3 = 90 are the new equations. I will attempt x as 3, to see if it's a true value. 29(3) is 87, and 87 + 3 is 90, so 3 is true there. 31(3) is 93, and 93 - 3 is also 90. So x is 3 in both cases

6. We already know one of the angles is 50 degrees. These are complementary, so subtract 50 from 180 to get 130 degrees. So, the equation is x + 137 = 130, which then becomes, 137 + -x = 130. 137 minus 30 is 7, so x is -7.

Answer:

1.) 75°

2.) 89°

3.) 90°  x = 3

4.) 112°

5.) 111°   x = 8

6.) 130°  x = -7

Step-by-step explanation:

1.) They are vertical so they measure the same

2.) They are corresponding angles so they equal the same

3.) They should equal up to 180.

29x + 3 = 31x - 3 (subtract 29x on both sides)

3 = 2x - 3 (add 3 on both sides)

6 = 2x (divide by 2 on both sides)

3 = x Plug in. 29(3) + 3 = 90 Both angles equal 90 degrees

4.) They should equal up to 180. 180 - 68 = 112

5.) They should equal up to 180. They are same side interior angles.                                                                             69 + 12x + 15 = 180 (collect like terms)

84 + 12x = 180 (subtract 84 on both sides)

12x = 96 (divide by 12 on both sides)

x = 8 Plug in 12(8) + 15 = 111 degrees

6.) They should equal up to 180.

x + 137 + 50 = 180 (collect like terms)

x + 187 = 180 (subtract 187 on both sides)

x = -7 Plug in -7 + 137 + 50 = 180 (collect like terms) 180= 180

Answer: 11/12

Step-by-step explanation:

7/12 and 1/3 don’t have the same denominator, so you can’t just add them right away. You have to give them the same bottom number. 1/3 = 4/12, so you can do it like this:

7/12 + 4/12 = 11/12

11/12 is in simplest form, so that should be correct! Hope this helps! :)

Answer:

[tex]Profit\% = 25\%[/tex]

Step-by-step explanation:

Given

Let the cost price be x

The profit be y

Required

Determine the profit percentage:

According to the question; profit =  1/4 of cost price.

So:

[tex]y =\frac{1}{4}x[/tex]

The percentage profit is then calculated as:

[tex]Profit\% = \frac{Profit}{Cost\ Price} * 100\%[/tex]

This gives:

[tex]Profit\% = \frac{Profit}{Cost\ Price} * 100\%[/tex]

Substitute values for profit and cost price

[tex]Profit\% = \frac{\frac{1}{4}x}{x} * 100\%[/tex]

[tex]Profit\% = \frac{1}{4} * 100\%[/tex]

[tex]Profit\% = \frac{1 * 100\%}{4}[/tex]

[tex]Profit\% = 25\%[/tex]

Step-by-step explanation:

The two integers 143m, 143n  = a, b  have only the factor of 143 in common.....and it is the g c d of both given , two positive integers of a and b is = 1001 factors 0f 1001is = 7 x 11 x 13 So.....143 is the greatest proper divisor of 1001.This means, that we have  143( m + n)  = 143m + 143m = a + b = 1001,  where ( m + n) = 7  and,

 m + n are two positive integers whose sum = 7,

they are relatively prime to each other.

Therefore, these two integer 143m, 143n  = a, b  have only the factor of 143 in common.....and it is the g c d of both

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.

Integers come in three types: Zero (0) Positive Integers (Natural numbers) Negative Integers (Additive inverse of Natural Numbers)

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043. A set of integers, which is represented as Z, includes: Positive Numbers: A number is positive if it is greater than zero.
