The area of a square playground (in square feet) can be represented by x2 - 30x + 225. How many feet is the perimeter of the playground if x = 25?

Answer:

Mai is 12 and Mai's mother would be 40.

Answer:

8:00 in the morning .....

Answer:

7:20 pm

Step-by-step explanation:

the phrase "twenty to seven in the evening" implies that is twenty minutes before 7:00 pm, meaning the current time was 6:40 pm.

Adding the 40 minutes it took Harmony to get home, the time would have been 7:20 pm

Answer:

105$

Step-by-step explanation:

We are told that she starts with 50$

We are also that after 30 years she earns 110% on interest

Given this information we need to find the value of the bond after the 30 years

To do so we take 110% of the initial value (50$) and add that to the initial value

So the answer = 110%(50) + 50

110%*50=55

55+50=105

So in 30 years the bond will be worth 105$

Answer:

28in, 195in, 197in

Step-by-step explanation:

There's no "supereasy" way to solve it, except by computation or approximation.

e.g. 2 3 6 couldn't work, because 2+3 < 6 so it's not even a triangle

125^2 cannot equal 122^2 + 30^2, because 125^2 is odd and 122^2 and 30^2 are even

23^2 + 18^2 = 529 + 324 < 900 < 31^2

So it has to be the last one, and after verification we find it checks out and 28^2 + 195^2 = 197^2

Answer:

x=−8 and y=−4

Step-by-step explanation:

8x−17y=4;−8x+15y=4

add eqn1 and 2

to eliminate x

you will get y=-4

put it zin eqn 1

x=-8

-4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16 -17 -18 -19 -20

Answer:

A) y=2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-5)/(6-4)

m=4/2

m=2

y-y1=m(x-x1)

y-5=2(x-4)

y=2x-8+5

y=2x-3

Answer:

linear

Step-by-step explanation:

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

sum of angles on a straight line is 180° thus linear angle is also be 180° when the two angles a and b combine

The Greatest Common Factor (GCF) for 70 and 98, notation CGF(70,98), is 14.

Step-by-step explanation:

Answer:

A 21/4

Step-by-step explanation:

When forming a perfect square trinomial you need to "complete the square".

All of the steps to completing the square when solving an equation:

1.  The leading coefficient must be 1.  

2.  Divide b by 2.

3.  Square (b/2)

4.  Add (b/2)^2 to both sides to keep the polynomial balanced.

5.  You can now write the perfect square trinomial and solve.

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4

Answer:

x = 42.5

Step-by-step explanation:

A triangle formed inside of a circle using the diameter as one of its side lengths is a right triangle

The right angle would be the angle opposite of the diameter (∠C)

A right angle has a measure of 90°

That being said we use this equation to solve for x

90 = 2x + 5

step 1 subtract 5 from each side

90 - 5 = 85

5 - 5 cancels out

now we have 85 = 2x

step 2 divide each side by 2

85/2=42.5

2x/2=x

we're left with x = 42.5

Answer:

The function that describes the height of the ball in time is  [tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex].

Step-by-step explanation:

Let suppose that ball experiments a free fall motion, which means that the ball is accelerated because of gravity and gravitational acceleration can be considered constant since height reached by the object is too small in comparison with the radius of the Earth. Therefore, we can assume that ball is accelerated uniformly.

Hence, the kinematic formula for the height of the ball ([tex]h(t)[/tex]), in feet, is described below:

[tex]h(t) = s + v\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)

Where:

[tex]s[/tex] - Initial height with respect to the ground, in feet.

[tex]v[/tex] - Initial velocity, in feet per second.

[tex]t[/tex] - Time, in seconds.

[tex]g[/tex] - Gravitational acceleration, in feet per square second.

If we know that [tex]s = 0\,ft[/tex], [tex]v = 32\,\frac{ft}{s^{2}}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that describes the height of the ball in time is:

[tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex] (2)
