The blueprint of a rectangular fountain shows that the length will be 7 feet longer than twice it's width. The area of the recta

bazaltina [42]

Answer:

D .(w)(2w+7)=85

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a rectangle: width x length

Since the length will be 7 feet longer than twice its width (w).

So, to obtain the length we have to multiply the width by 2 (twice) and add 7.

Mathematically speaking:

Length: 2w+7

Back with the area formula:

Area of a rectangle: length x width

Replacing with the values given:

85 = w (2w+7)

Note: option D correct equation is D .(w)(2w+7)=85, since we don't have x variables.

Susan was thinking of a number that when she multiplies it by two and then

Gnesinka [82]

Answer:

-4

Step-by-step explanation:

Let the number be x

If she multiplies the number by 2, it will become 2x

If divided by 4, it will be 2x/4, if she multiplies the result by itself, we will have:

2x/4(2x/4) = 4x/16

If she subtract the original number from 6 and divide by 10, we will have;

x-6/10

Equating both expressions

4x/16 = x-6/10

Cross multiply

4x(10)= 16(x-6)

40x =16x-96

40x-16x = -96

24x = -96

x = -96/24

x = -4

Hence the number is -4

A circle has a sector with area 1/2π and central angle of 1/9π radians . What is the area of the circle? Either enter an exact a

Agata [3.3K]

Answer:

$9\pi$

Step-by-step explanation:

The area of a sector is given by;

$A= \frac{1}{2} {r}^{2} \theta$

From the given information, the central angle is

$\theta = \frac{ \pi}{9}$

and

$A= \frac{\pi}{2}$

Let us substitute and solve for the radius, r.

$\frac{ \pi}{2} = \frac{1}{2} \times {r}^{2} \times \frac{ \pi}{9}$

$1 = \frac{ {r}^{2} }{9}$

${r}^{2} = 9$

$r = \sqrt{9} = 3 \: units$

The area of a circle is given by:

$= \pi \: {r}^{2}$

Substitute the radius to get:

$= \pi \times {3}^{2} \\ = 9\pi$

Answer: m=6.2t, 148.8 miles

Step-by-step explanation:

to figure out the equation we do 93/15=6.2 and we make it into a equation which is m=6.2t. since we know the butterfly travels 6.2 per hour we do 6.2 x 24 = 148.8

sorry if it's wrong
