8−4(−x+5)

Answer:

12

Step-by-step explanation:

The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!

What is 19 percent (calculated percentage %) of number 50? Answer: 9.5.

Step-by-step explanation:

Answer:

9.5

Step-by-step explanation:

19% of 50

Convert the percentage to a decimal.

19% = 0.19

Multiply the decimal by the number.

50 × 0.19 = 9.5

9.5 is the answer.

Answer:

216

Step-by-step explanation:

I think that it is 216 because if you add 18 and 10 you get 28 then multiply 28 by 12 then you get 336. Then you will find the area of the unshaded part which is 120. Then you will subtract 120 from 336 to get 216.

Omg, thank you so much

Step-by-step explanation:

We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.

We will use arc length formula to solve our given problem.

[tex]\text{Arc length}=2\pi r\cdot \frac{\theta}{360^{\circ}}[/tex], where,

r = Radius of circle,

[tex]\theta[/tex] = Central angle corresponding to arc.

We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.

[tex]78=2\cdot 3.14\cdot r\cdot \frac{70^{\circ}}{360^{\circ}}[/tex]

[tex]78=2\cdot 3.14\cdot r\cdot \frac{7}{36}[/tex]

[tex]78= 3.14\cdot r\cdot \frac{7}{18}[/tex]

[tex]78= r\cdot \frac{21.98}{18}[/tex]

[tex]r\cdot \frac{21.98}{18}=78[/tex]

[tex]r\cdot \frac{21.98}{18}\cdot \frac{18}{21.98}=78\cdot \frac{18}{21.98}[/tex]

[tex]r=63.8762511373[/tex]

Upon rounding to nearest hundredth, we will get:

[tex]r\approx 63.88[/tex]

Therefore, the radius of circle H is approximately 63.88 miles.

Answer:

the length of the side XY is 4 units

Step-by-step explanation:

To find the length of side XY, what we do is to find the distance between the points X and Y

To find this distance, we employ the use of the formula for finding the distance between two points on a Cartesian plane.

Mathematically, the distance d which represents the length XY is given by;

d = √{(x2-x1)^2 + (y2-y1)^2}

Where point X represents the coordinates (x1,y1) = (10,1) while point Y represents the coordinates (x2,y2) = (10,-3)

Plugging these values into the formula, we have;

d = √{(10-10)^2 + (-3-1)^2}

d = √{(0)^2 + (-4)^2}

d = √(0 + 16)

d = √(16)

d = ± 4

but since distance cannot be negative, we ignore the -4 and thus we choose 4 units as the length between the points XY

Answer:

4 units

Answer:

x= 2 and x= -6

Step-by-step explanation:

3(x+2)^2=48

1)   [3(x+2)^2]/3=48/3

2) (x+2)^2 = 16

3) √(x+2)^2 =+/-√16

4) x+2 = 4   and    x+2 = -4

5) x=2          and   x= - 6

Check:

3(x+2)^2=48

3(2+2)^2 = 48           and        3(-6+2)^2=48

48 = 48                                   48=48

Answer: The answer is 10,000

Step-by-step explanation:

10^4 is equal to 10,000

10^4 to the second power means that you have too add 4 zeros to the end of the number.

Since 10 already has a 0, you would add 3 more.

Therefore, the answer would be 10,000.

Answer:

1407.43

Step-by-step explanation:

The amount in equation is 5d + 3h + 8s = 231.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given:

Jeremy had 5 Roosevelt dimes,

3 Kennedy half dollars,

and 8 silver dollars in his coin.

Total amount = $231

As, let d be the collector value of a dime

let h be the collector value of a half dollar

let s be the collector value of a silver dollar

Now, to represent the amount in equation

5d + 3h + 8s = 231

Answer:

First Option; 40,

Second Option; x = 3,

Third Option; x = - 5,

Fourth Option; x = 0

Step-by-step explanation:

Given the expression x^2 + 3 * ( x + 4 ), where x = 4;

x^2 + 3 * ( x + 4 ) ⇒ Substitute the value of 4 in replacement of x,

( 4 )^2 + 3 * ( 4 + 4 ) ⇒ Add the terms in ( ), taking 4^2 at the same time,

16 + 3 * ( 8 ) ⇒ By PEMDAS, multiply 3 by 8 first,

16 + 24 ⇒ And now add the remaining terms,

Solution; 40

This next equation is given to be 5 * ( 2x - 1 ) = 25, where we must solve for x;

5 * ( 2x - 1 ) = 25 ⇒ Distribute the 5 to the terms in ( ),

10x - 5 = 25 ⇒ Add 5 on either side of the equation,

10x = 30 ⇒ Divide 10 on either side of equation,

Solution; x = 3

Here we must solve for the value of x provided the equation 6x + 4 - x = 2x - 11;

6x + 4 - x = 2x - 11 ⇒ Add 11 on either side,

6x + 15 - x = 2x ⇒ Add x on either side of equation,

6x + 15 = 3x ⇒ Subtract 6x on either side,

15 = - 3x ⇒ Divide 3 on either side,

Solution; x = - 5

Now we are given the equation 4 - ( 3x + 4 ) = - 9x, solving for the value of x;

4 - ( 3x + 4 ) = - 9x ⇒ Distribute the - 1 to all terms in ( ),

4 - 3x - 4 = - 9x ⇒ Add 3x on either side of equation,

4 - 4 = - 6x ⇒ Subtract 4 from 4,

0 = - 6x ⇒ Divide - 6 on either side,

Solution; x = 0

Answer:

Step-by-step explanation:

(1-3)/(5-1)= -2/4= -1/2

y - 3 = -1/2(x - 1)

y - 3 = (-1/2)x + 1/2

y - 6/2 = (-1/2)x + 1/2

y = (-1/2)x + 7/2

Answer:

Perimeter of the quadrilateral PQRS is 25 units

Step-by-step explanation:

From the figure attached,

PQ is a tangent to the given circle so m∠PQR = 90°

Now we apply Pythagoras theorem in the ΔPQR,

PR² = PQ² + QR²

(PT + TR)²= PQ² + 5²

(4 + 5)² = PQ² + 25

81 = PQ² + 25

PQ = √(81 - 25)

     = √56

     ≈ 7.5 units

PQ ≅ PS ≅ 7.5 units

[Since measures of tangents drawn from a point to a circle are always equal]

Perimeter of PQRS = PQ + QR + RS + PS

                                = 7.5 + 5 + 5 + 7.5

                                = 25 units

Therefore, perimeter of the quadrilateral PQRS is 25 units.

Answer:

so the person below or above me said 25 units and they are not wrong it just the did have it in a simple equation like this ^

so 4 square root 14 = 14.9 or 15

then 10 + 15 = 25 units
