Answer:

2x +5x-20+3x=180(angle of triangle)

10x-20=180

10x=180+20

10x=200

x=200/10

x=20

Answer:

[tex]x = 20[/tex]

Step-by-step explanation:

Angles in a triangle is added up to 180 degrees

So, You can simply Solve it like this

[tex]2x + 3x + 5x - 20 = 180 \\ 10x = 180 + 20 \\ 10x = 200 \\ \frac{10x}{10} = \frac{200}{10} \\ x = 20[/tex]

Hope this helps you.

Have a nice day!

Answer:

  45 yd²

Step-by-step explanation:

The area of a rectangle is the product of its length and width. If your given measures are the length and with of a rectangle, the area is found by multiplying them.

  A = LW

  A = (9 yd)(5 yd) = 9·5 yd·yd = 45 yd²

The area of a 9 yd by 5 yd rectangle is 45 square yards.

Answer:

Step-by-step explanation:

Length of chain Jesse needs = 10 1/4 feet

Length of chain Jesse has:

Two small pieces each measuring 2 1/8 feet

= 2 × 2 1/8 feet

= 2 × 17/8

= 34/8 feet

Third piece measuring 3 3/4 feet

Total Length of chain Jesse has = 34/8 feet + 3 3/4 feet

= 34/8 + 15/4

= 34+30/8

= 64/8

= 8 feet

Total Length of chain Jesse has = 8 feet

Length of chain Jesse needs to purchase = Length of chain Jesse needs - Total Length of chain Jesse has

= 10 1/4 feet - 8 feet

= 2 1/4 feet

Length of chain Jesse needs to purchase = 2 1/4 feet

Answer:

260 of dollars it costs to rent the house for 10 days

The number of dollars it costs to rent the house for 10 days

Step-by-step explanation:

F(x) = 10 + 25x

F(10) = 10 + 25*(10)

F(10) = 10 + 250

F(10) = 260 of dollars it costs to rent the house for 10 days

Here f (10) represent 260 of dollars it costs to rent the house for 10 days

Given that,

Based on the above information, the calculation is as follows:

F(x) = 10 + 25x

= 10 + 25(10)

= 10 + 250

 = 260 of dollars it costs to rent the house for 10 days

Answer:

A 90

Step-by-step explanation:

multiple ways to prove this.

e.g. since the angle between the two lines from the center of the circle to the 2 tangent touching points is 90 degrees (that is the meaning of these 90 degrees here as the angle of the circle segment defined by the 2 tangent touching points and the circle center), the tangents have the same "behavior" as tan and cot = the tangents at the norm circle at 0 and 90 degrees. they hit each other outside of the circle again at 90 degrees.

another way

imagine the two right triangles of the tangents crossing point to the circle center and the tangent/circle touching points.

the Hypotenuse of each triangle is cutting the 90 degree angle of the circle segment exactly in half (due to the symmetry principle). so the angle between radius side and Hypotenuse is 90/2 = 45 degrees.

that means also the angle of such a right triangle at the tangent crossing point is 45 degrees (as the sum of all angles in a triangle must be 180, we have the remainder of 180 - 90 - 45 = 45 degrees).

the angles of both right triangles at that point are the same, and so we can add 45+45 = 90 degrees for the total angle at the tangent crossing point.

Answer:

Sam is  yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister

Step-by-step explanation:

The relationship between the ages of the brothers are;

Sam's age + Dean's age = Their sister's age

Dean's age + 10 = Dean's age + Sam's age

Therefore, we have;

Sam's age = Dean's age + 10 - Dean's age = 10

Sam's age = 10 years

Let 'x' represent their sisters age, we get;

Sam's age + Dean's age = x

10 + Dean's age = x

Dean's age (in variable form) = x - 10

The Slope of DC: -1/5

The Slope of BC: 2/3

The Slope of AD: 2/3

The quadrilateral is a trapezoid because (only one pair of opposite sides is parallel)

Answer:

B

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 )

Here m = - 4 , then

y = - 4x + c ← is the partial equation

To find c substitute (- 2, - 5) into the partial equation

- 5 = 8 + c ⇒ c = - 5 - 8 = - 13

y = - 4x - 13 → B

Answer:

0.56

Step-by-step explanation:

The r-value that represents the most moderate correlation is 0.56

Correlation is represented with r.

And the range of values of r is:

-1 ≤ r ≤ 1

This means that r can take any value from -1 to 1

-1 and 1 are considered strong correlation

While values closer to 0.5 or - 0.5 are moderate

From the list of options,

0.56 is closer to 0.5 than others

Hence, the r-value that represents the most moderate correlation is 0.56

Answer:

x =12

Step-by-step explanation:

The two angles add to 90 degrees

4x+4 + 5x-22 = 90

Combine like terms

9x - 18 = 90

Add 18 to each side

9x -18+18 = 90+18

9x = 108

Divide each side by 9

9x/9 = 108/9

x =12

Answer:

C.) 52°

Step-by-step explanation:

find x first

4x + 4 + 5x - 22 = 90

9x - 18 = 90

9x = 108

x = 12

plug it into the expression

4(12) + 4

[tex]x = 7 + - \sqrt{30} [/tex]

The roots of f(x) are 7+root 30 and 7 -root 30.

We have given that the quadratic equation is

[tex]f(x)=x^2-14x+19[/tex]

We have to find the zeros of the given f(x)

Compaire the given equation with the general form of quadratic equation

[tex]ax^2+bx+c=0[/tex]

So we get,a=1,b=-14,c=19

We find the roots by using the quadratic formula method

[tex]x_{1,2}=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]

Use the value of a,b and c in above formula we get,

[tex]x_{1,2}=\frac{-(-14)\±\sqrt{(-14)^2-4(1)(19)} }{2(1)}[/tex]

[tex]x_{1,\:2}=\frac{-\left(-14\right)\pm \:2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]x_1=\frac{-\left(-14\right)+2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]=\frac{14+2\sqrt{30}}{2}[/tex]

[tex]=\frac{14+2\sqrt{30}}{2}[/tex]

[tex]=\frac{2\left(7+\sqrt{30}\right)}{2}[/tex]

[tex]=7+\sqrt{30}[/tex]

Similarly, we get,

[tex]x_2=\frac{-\left(-14\right)-2\sqrt{30}}{2\cdot \:1}[/tex]

[tex]x_2=7-\sqrt{30}[/tex]

Therefore the roots of f(x) are 7+root 30 and 7 -root 30.

To find:

The cost price of the item.

Solution:

Let x be the cost price of the item.

The item was sold at a loss of 20%. Then selling selling price is:

[tex]S.P.=x-\dfrac{20}{100}x[/tex]

[tex]S.P.=x-0.2x[/tex]

[tex]S.P.=0.8x[/tex]

If a the item is sold for 5% profit, then the selling price is:

[tex]S.P.=x+\dfrac{5}{100}x[/tex]

[tex]S.P.=x+0.05x[/tex]

[tex]S.P.=1.05x[/tex]

It is given that, if the item is sol for Rs. 50 more then, the profit would have been 5%. So,

[tex]0.8x+50=1.05x[/tex]

[tex]50=1.05x-0.8x[/tex]
