The area of a rectangular playground is 16 square yards. The length of the playground is 4 times longer than

Alexxandr [17]

length = 8 yd and width = 2 yd

So, Option D is correct.

Step-by-step explanation:

Area of rectangular playground = 16 square yards

Width of playground = w

Length of playground = l = 4w

We need to find length(l) and width(w)

The formula used is:

$Area = Length * Width$

Putting values:

$Area = Length * Width\\16=4w*w\\16=4w^2\\w^2=\frac{16}{4}\\w^2=4\\Taking\,\,square\,\,root:\\\sqrt{w^2}=\sqrt{4}\\ w=\pm 2$

Since width of rectangle is always positive, so we will take w = 2

So. Width = 2

Length = 4w = 4(2) = 8

Hence, length = 8 yd and width = 2 yd

So, Option D is correct.

Awsner this with step by step (can use calculator)

ss7ja [257]

Answer:

$x = 9.2$

$x =22.0$

$x = 8.7$

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

$\tan(57) = \frac{x}{6}$

Make x the subject

$x = 6 * \tan(57)$

$x = 6 * 1.5399$

$x = 9.2394$

$x = 9.2$ --- approximated

(b):

x is calculated using cosine formula

$\cos(60) = \frac{11}{x}$

Make x the subject

$x = \frac{11}{\cos(60)}$

$x = \frac{11}{0.5}$

$x =22.0$

(c):

x is calculated using sine formula

$\sin(60) = \frac{x}{10}$

Make x the subject

$x = 10 * \sin(60)$

$x = 10 * 0.8660$

$x = 8.660$

$x = 8.7$ --- approximated

Graph the equation (x - 3)^2 + (y - 2)^2 = 25 and y = 6.

Dmitriy789 [7]

Answer:

x=6, x=0

Step-by-step explanation:

$(x - 3) ^{2}$ + $(y - 2) ^{2}$ = 25

$(x - 3) ^{2}$ + $(6 - 2) ^{2}$ = 25

x=6, x=0
