Alice was sitting on a dock looking at a lake. She picked up a stone and through it in the air and out

toward the lake. It seemed like it was in the air for a long time. The equation that can be used to

model the height of the stone (in feet) as it relates to the time in the air in seconds) is given by

h(t) = 5 + 50 - 16t2. In order to solve for how long the stone was in the air, Alice will need to use the

quadratic equation which is:

Answer:

B which is 2/4.

Step-by-step explanation:

Elin: worked for 2/4 + 1/4 = 3/4 of an hour on an assignment

Jocyln worked for 5/4 of an hour the same   assignment

The difference in time is 5/4 - 3/4 = 2/4 or 1/2 hour.

Note: when you subtract fractions, the denominators must be the same. What you subtract is the numerators (top part of the fraction).

Answer:

135ft^2

Step-by-step explanation:

area of trapzoid= (a+b)/(2)×h

area of traingle= 1/2(b)(h)

area of the shaded region equals (a+b)/(2)×h-1/2(b)(h)

so

(8+18)/(2)×15-(1/2)(8)(15)

=135ft^2

Answer:

The value of x = 110°

Step-by-step explanation:

=> x° + 90° + 90° + 70° = 360 ° { sum of angles of a quadrilateral is 360 }

=> x + 250° = 360°

=> x = 360 - 250

=> x = 110°

Answer:

468 m²

Step-by-step explanation:

Given:

→ Base = 26 m

→ Height = 18 m

Formula:

[tex]\text{Area of parallelogram: Base} \times \text{Height}[/tex]

To determine the area of the parallelogram, we need to substitute the base and the height in the formula.

Substitute the measures in the formula:

[tex]\implies \text{Area of parallelogram: Base} \times \text{Height}[/tex]

[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]

Evaluate the area of the parallelogram:

[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]

[tex]\implies \text{Area of parallelogram}= \bold{468 \ \text{m}^{2}}[/tex]

Answer:

468 m²

Step-by-step explanation:

Given,

Base ( b ) = 26 m

Height ( h ) = 18 m

To find : The area of parallelogram

Formula : -

Area of parallelogram = bh

Area of paralleogram

= 26 x 18

= 468 m²

Therefore,

the area of the parallelogram is 468 m².

Answer:

false, because cos(x) has no definite answer, and equations aren't identities

Step-by-step explanation:

Answer:

180-20 = 160 = sum of the other two angles

3/(3+5) = 3/8 x 160 = 60 degrees

5/(3+5) = 5/8 x 160 = 100 degrees

or in radians the other two angles are pi/3 and 5pi/9

1 pound = .73 dollars rounded.

Step-by-step explanation:

This is like a rate question. Speed is in miles / hour only the units for this question is pound / dollar.

pounds = 33

dollars = 45

1 pound is 33/45

1 pound = 0.73

Step-by-step explanation:

Sonia will take $57, and his grandparents will give another $78. 57 + 78 = 135. Sonia will have 135 dollars, but it is a 9 day vacation, so 135/9 = 15

Sonia will spend 15 dollars a day.

Answer:

C. Chloe forgot to arrange the numbers in ascending order. The median is 44.

Step-by-step explanation:

We arrange the 9 numbers of the data from the least to the greatest

Then we spot the middle number (5th number) which is 44:

34 < 37 < 38 < 42 < 44 < 51 < 55 < 56 < 57

An equation is formed of two equal expressions. The solution of the equation √(x+12)=x is x=4.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of the equation √(x+12)=x can be done as,

[tex]\sqrt{x+12} = x\\\\\text{Square both the sides of the equation}\\\\x+12=x^2\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x-4)(x+3)=0[/tex]

Equate each of the factors with 0,

[tex](x-4)=0\\x=4\\\\(x+3)=0\\x=-3[/tex]

Now, if we substitute the value of x in the equation given, only the value of x as 4 will satisfy the equation.

Thus, the solution of the equation √(x+12)=x is x=4.

Answer:

95

Step-by-step explanation:

So if you wanted to figure the average of the 3 tests, you would add 91+85+89 to get 265 & then divide by 3 tests  to get an average of 88.

So that means for four tests, 91+85+89+4th test = answer that divided by 4 tests will equal 90.  90 x 4 = 360.  Then 360 -265 (sum for 1st 3 tests) = 95

Answer:

Step-by-step explanation:

Remark

The way to solve the shaded region is to find the area of the square first and subtract the area of the circle from it.

Area of the square

Area = s^2

s = 12

Area of the square = 12 * 12

Area of the square = 144 yd^2

Area of the circle = pi * r^2

r = d/2

d is actually the same as the side length of the square

r = 12/2

r = 6

pi = 3.14

Area of the circle = pi * 6^2

Area of the circle = 3.14 * 36

Area of the circle = 113.04

Area of the shaded region

Area of shaded region = area of the square - area of circle

Area of shaded region = 144 - 113.04

Answer: Area of the shaded region 30.96
