Answer:

x = -6

Step-by-step explanation:

Answer:

x = 49

Step-by-step explanation:

Given the mathematical expression and data;

y = 1/√x

y = 7 and x = 64

First of all, we would find the constant of proportionality, k;

y = k/√x

7 = k/√64

7 = k/8

k = 7 * 8

k = 56

Next, to find the value of x, when y = 8

y = k/√x

Substituting the values, we have;

8 = 56/√x

Cross-multiplying, we have;

8 * √x = 56

√x = 56/8

√x = 7

Taking the square of both sides, we have;

(√x)² = 7²

x = 49

Answer:

25 :)

Step-by-step explanation:

Answer:

x = 75°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

78° + 27° + x° = 180°

Add like terms

105 + x = 180

105 + x - 105 = 180 - 105 (substraction property of equality)

x = 75°

Answer:

B. Parallelogram

Step-by-step explanation:

The opposite sides of the quadrilateral are equal and so the quadrilateral is a rectangle, the correct option is A.

A quadrilateral is a polygon with four sides.

The coordinates of a quadrilateral are:

A(7,0), B(3, 1), C(4,7), and D(8, 6)

The distance between the coordinates has to be determined to identify the type of quadrilateral

The distance formula is

[tex]\rm D = \sqrt { ( x- x_1)^2 + (y-y_1)^2}[/tex]

[tex]\rm AB = \sqrt { (3-7)^2 + (1-0)^2}\\AB = \sqrt { 17}[/tex]

[tex]\rm BC = \sqrt { ( 1)^2 + (6)^2}\\BC = \sqrt {37}[/tex]

Similarly,

[tex]\rm CD= \sqrt { 17}\\\\AD = \sqrt{37}[/tex]

The opposite sides of the quadrilateral are equal and so it is a rectangle.

Answer:

the object will fall 792 feet in 17 seconds

Step-by-step explanation:

first you can do 144 multiplied by 5 because that would be 15 of those seconds next you would do 144 divided by 2 because you only need 2 seconds to reach 17 your answer would be 72 then you would do 720+72=792 so it would fall 792ft in 17 seconds

Step-by-step explanation:

Assuming the Height is denoted by "h" and the time by "t" , h=kt² since h varies as t².

When h=144ft , t=3

k=h/t²

k=144/3²

k= 16

This implies that h=16t² is the relation to be used.

Therefore when t= 17s, h=16*17²

h=4624ft

Answer:

V = 3085 in³

Step-by-step explanation:

The volume is given by:

[tex] V = A*h [/tex]

Where:

A: is the area

h: is the height = 7 in

The area of the polygon can be found by using the given equation:

[tex] A = \frac{1}{2}a*p [/tex]

Where:  

a: is the apothem = 11.3 in

p: is the perimeter

The perimeter is:

[tex] p = 13*6 = 78 in [/tex]      

Hence, the volume is:

[tex] V = A*h = \frac{1}{2}a*p*h = \frac{1}{2}11.3 in*78 in*7 in = 3085 in^{3} [/tex]

Step-by-step explanation:

Answer: -18.27 per year

Step-by-step explanation:

The difference in years is:

= 2015 - 2004

= 11 years

In those 11 years, the runs decreased from 949 to 748.

The total decrease is:

= 949 - 748

= 201 runs

The rate of change is:

= 201 / 11

= 18.27 per year

Since it is reducing, the rate is:

= -18.27 per year

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Answer:

B. $16.13

Step-by-step explanation:

The Total Students= 82+74+96+99=351

Sum of earnings of 82 seniors = $26.75 x 82 = $ 2193.5

Sum of earnings of 74 juniors = $ 12.25 x 74 = $ 906.5

Sum of earnings of 96 sophomores = $15.50 x 96 = $ 1488

Sum of earnings of 99 freshmen= $ 10.85 x 99 = $ 1074.15

Total earnings = $2193.5 + $ 906.5 + $1488 + $ 1074.15 = $ 5662.15

( Total Earnings) ÷ (Total Students)

= $5662.15 ÷ 351

= $16.13
