I believe the answer is 4 from what it looks like it should be because of three lengths on the sides

The missing length is 6ft

if you subtract 14ft from 8ft, you get 6ft which is the missing length

Leya [2.2K]

If there is a 5% drop every month, then the class becomes 1-5%=1-0.05=0.95 times the previous size.

The formula for $t$ months would be
$100*0.95^{t}$
so for 12 months it would be
$100*0.95^{12}\approx 54$

Find the value of two numbers if their sum is 19 and and their difference is 5

sergij07 [2.7K]

Answer:

7 and 12

Step-by-step explanation:

x - y = 5

y = (5+x)

x+ (5+x) = 19

2x +5 = 19

2x = 14

x = 7

19-7 = 12

12 +7 = 19

12-7 = 5

Solve using the quadratic formula:

timurjin [86]

Answer:

$\boxed{x_1 = \frac{7 + \sqrt{5} }{2} ~~or~~x_2 = \frac{7 - \sqrt{5} }{2} }$

Step-by-step explanation:

$x^2 - 7x + 11 = 0$

$x^2 - 7x = -11$

$(x - \frac{7}{2} )^2 - \frac{49}{4} = -11$

$(x - \frac{7}{2} )^2 = -11 + \frac{49}{4}$

$(x - \frac{7}{2} )^2 = \frac{5}{4}$

$x - \frac{7}{2} = \pm \sqrt{\frac{5}{4}}$

$x = \frac{7 \pm \sqrt{5} }{2}$

Find the volume of the following solid:

Nadya [2.5K]

Answer:

390cm³

Step-by-step explanation:

IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.

All you need to do is solve for the volume of each prism and add them up together.

The formula to use to get the volume of a rectangular prism is:

$V=whl$

Where:

V = Volume

w = width

l = length

h = height

Let's get the first one and double it because you have rectangular prisms with the same dimensions:

$V = wlh\\\\V= (5cm)(2cm)(12cm) = 120cm^3\\\\120cm^3 \times 2=240cm^3$

Next we get the rectangular prism in the middle:

Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.

12cm - (5cm + 2cm)

12 cm - 7cm = 5cm

Then we plug it into the formula

$V = wlh\\\\V= (5cm)(6cm)(5cm) = 150cm^3$
