mr Goodwill [35]

Answer:

decrease of 80%

Step-by-step explanation:

See image.

Use variables for the fraction.

Numerator means the top number.

Denominator means the bottom number.

Change percents to decimals to calculate.

.8 is 80%.

80% will make the whole fraction smaller.

Find the distance between the points (-3, 9) and (6,-5). Round the answer to the nearest tenth.

inna [77]

Answer:

D. 16.6

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-3,9)$

$(x_2,y_2) = (6,-5)$

Replacing these values in the distance formula

$D =\sqrt{(-3-6)^2+(9-(-5))^2}$

$D =\sqrt{(-9)^2+(9+5)^2}$

$D =\sqrt{(-9)^2+(14)^2}$

$D =\sqrt{81+196}$

$D =\sqrt{277}$

$D= 16.6433$

Hence the Distance is 16.60 units

A rectangular swimming pool has a perimeter of 96 ft. The area of the pool is 504 ft2. Which system of equations models this sit

gregori [183]

Answer:

2l + 2w = 96 ..... eqn1

lw = 504 ...... eqn2

Step-by-step explanation:

To model this case where we have two unknowns l and w, we need two equations.

Firstly, the perimeter of a rectangle is given by

2l + 2w = p

Where l,w and p are length, width and perimeter of the rectangle respectively.

Hence,

2l + 2w = 96 ... eqn1

Secondly, the area of a rectangle is given by

Length × width = Area

Hence,

l × w = 504

lw = 504 ... eqn2

With these two equations the solutions to the length and width of the rectangular pool can be derived.
