Answer:

  about 11.856 time units

Step-by-step explanation:

We have to assume the equation has something to do with the path of the ball relative to the ground. Perhaps it represents height, with t representing time. The height (h) will be zero for the values of t that satisfy ...

  0 = -t^2 +10t +22

Using the quadratic formula, we can find the values of t that satisfy this equation:

  t = (-10 ±√(10² -4(-1)(22)))/(2(-1)) = (-10 ±√188)/-2 = 5±√47

The value of h is zero for t ≈ 11.856.

About the quadratic formula

The quadratic formula tells you the solution to ...

  ax^2 +bx +c = 0

is given by ...

  x = (-b ±√(b^2 -4ac))/(2a)

Matching this form to the given equation, we see a=-1, b=10, c=22. The variable used in the given equation is t, instead of x.

Answer:

x=28

Step-by-step explanation:

The interior angles of a triangle must add to 180 degrees.

Therefore,

x+95+57=180

Add 95 and 57

x+152=180

We are trying to find x. In order to do this, we must get x by itself. 152 is being added to x. The opposite of addition is subtraction. So subtract 152 from both sides.

x+152-152=180-152

x=180-152

x=28

Let’s check our answer. Add all the angles together, to be sure they add to 180 degrees.

x+95+57=180

Substitute 28 for x

28+95+57=180

180=180

The equation above is true, so we know that x is equal to 28.

____________________________________

Hey!!

Solution:

X+95+57=180 (sum of angle in triangle)

or,X+152=180

or,X=180-152

X=28 degree.

The value of X is 28 degree.

Answer:

Step-by-step explanation:

Let ∠A = x

Therefore, ∠A = ∠B = ∠C = x

The sum of all angles of a quadrilateral is 360

∠D + ∠A + ∠B + ∠C =360

150 +x + x + x =360

150 + 3x = 360

3x = 360 - 150

3x = 210

x = 210/3

x = 70

∠A = ∠B = ∠C = x = 70°

Answer:

540°

Step-by-step explanation:

The sum of all the interior angles in a pentagon with 5 sides is 540°.

Answer:

540°

Step-by-step explanation:

Using the formula for finding the sum of interior angles of polygons

(n-2)×180

Where n is no. Of sides

For pentagon (5 sides) it will be

=(5-2)×180

=(3)×180

=540

So angles of a pentagon add up to 540°

Answer:

G > 16

Step-by-step explanation:

The expression "more than" 16 gold pieces per day means that the number of gold pieces Kwame earns each day (G) must be greater than 16. In order to represent that as an inequality, we should use the greater-than sign: >.

The inequality that describes the number of gold pieces Kwame must earn per day  is G > 16.

Answer:

On the first equation, which is (c-d)/5 - 2 = 0 Let's start by solving c.

First, you need to add 1/5d to both sides:

1/5 c + -1/5 d - 2 + 1/5 d = 0 + 1/5 d

1/5 c - 2 = 1/5 d

Next, add 2 to both sides:

1/5 c - 2 + 2 = 1/5 d + 2

1/5 c = 1/5 d + 2

Now, divide both sides by 1/5:

1/5 c/ 1/5 = 1/5 d + 2/ 1/5

c = d + 10

so, therefore, your answer is c = d + 10

____________________________________________________________

Now we are going to do the 2nd equation, which is c-6d=0 Lets solve c.

The only thing you need to do is you need to add 6d to both sides:

c − 6d + 6d = 0 + 6d

c = 6d

So, therefore, your answer is c = 6d

Answer:

0 ≤ x ≤ 18

Step-by-step explanation:

Let 'x' be the number of youth tickets purchased at the zoo and 'y' be the number of adult tickets purchased at the zoo.

At a zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. We can write as

5x + 9y = 90

to find x we divide both side by 5

x = (90-9y)/5 =>  90/5 - 9y/5

x = 18 - 9y/5

The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is

0 ≤ x ≤ 18

At x = 0, it means only adult tickets were purchased.

At x = 18, it means only youth tickets were purchased.

Answer:

0 ≤ x ≤ 18

d = 3√2

Step-by-step explanation:

Distance formula: [tex]d = \sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]

Answer:

523.8 miles

Step-by-step explanation:

The drawing attached represents the question. We create a triangle with the distances from each pair of cities, and we call the distance from B to C by 'd'.

First, we need to find the angle BAC:

55° + BAC + 7° = 90°

BAC = 28°

Then, we can use the law of cosines to find the value of d:

d^2 = 470^2 + 890^2 - 2*470*890*cos(BAC)

d^2 = 470^2 + 890^2 - 2*470*890*0.8829

d^2 = 274365.86

d = 523.8 miles

Answer:

Step-by-step explanation:

what language are you speaking what the heck

Answer:

Option A

radius = 13 units

height = 20 units

Volume of the cylinder = πr²h

= π (13)² ×20

=3380π cu. units

The volume of the cylinder will be 3380 π cubic units. Then the correct option is A.

Let r be the radius and h be the height of the cylinder.

Then the volume of the cylinder will be

V = π r²h cubic units

The radius is 13 and height is 20.

Then the volume of the cylinder will be

V = π (13)² x 20

V = 3380 π cubic units

Then the correct option is A.

Answer:

Options (A), (B) and (C)

Step-by-step explanation:

In the given figure,

Length of side AD = 16 units

If this side is scaled by a factor = k

Then the length of the corresponding side will be = 16k

If 0 < k < 1,

Then length of the corresponding side will be less than 16.

[Example: If k = [tex]\frac{1}{4}[/tex]

Therefore, scaled side of the corresponding side of the quadrilateral = [tex]16\times \frac{1}{4}[/tex] = 4]

That means length of corresponding sides may be 4, 6.5 and 12.

Options (A), (B) and (C) will be the answer.
